    Congressional Oversight of the White House
    Congressional oversight of the White House is subject to greater constitutional limitations
    than oversight of the departments and agencies of the Executive Branch, in light of the
    White House staff’s important role in advising and assisting the President in the dis-
    charge of his constitutional responsibilities, the need to ensure the independence of the
    Presidency, and the heightened confidentiality interests in White House communica-
    tions.

    MEMORANDUM OPINION FOR THE COUNSEL TO THE PRESIDENT
    This memorandum opinion summarizes the principles and practices
    governing congressional oversight of the White House. The White House,
    as we use the term here, refers to those components within the Executive
    Office of the President (“EOP”), such as the White House Office and the
    National Security Council, whose principal function is to advise and assist
    the President in the discharge of the duties of his office. All three branch-
    es of government have recognized that the White House has a role and
    status distinct from the executive branch departments and agencies, and
    this Office has long recognized those distinctions to be critical to the
    development of principles and practices for congressional oversight
    addressed to the White House.
    The Constitution vests all of “[t]he executive Power” in the President
    and charges him alone with the responsibility to “take Care that the Laws
    be faithfully executed.” U.S. Const. art. II, § 1, cl. 1; id. § 3. In carrying
    out that charge, the President necessarily depends on “the assistance of
    subordinates,” Myers v. United States, 
    272 U.S. 52
    , 117 (1926), most of
    whom are his appointed officials in the executive departments and agen-
    cies. Yet the size and complexity of modern federal administration have
    required the establishment of the White House as an organizational appa-
    ratus to directly support the President in the discharge of his responsibili-
    ties. White House personnel work in close proximity to the President and
    advise and assist him in the development of presidential policy, in super-
    vising and guiding the affairs of the executive branch departments and
    agencies, and in communicating with Congress, the American public, and
    foreign governments.

    45 Op. O.L.C. __ (Jan. 8, 2021)
    The White House’s important role in advising and assisting the Presi-
    dent has special significance for congressional oversight. Each House of
    Congress has, as an adjunct to its legislative power, the constitutional
    authority to obtain information, a power typically carried out through its
    committees. But this investigative authority, often referred to as “over-
    sight” authority, is subject to limitations. A congressional information
    request “is valid only if it is ‘related to, and in furtherance of, a legitimate
    task of the Congress.’” Trump v. Mazars USA, LLP, 
    140 S. Ct. 2019
    , 2031
    (2020) (quoting Watkins v. United States, 
    354 U.S. 178
    , 187 (1957)).
    Consequently, the Executive Branch must scrutinize the asserted legisla-
    tive purpose underlying a congressional request by examining the objec-
    tive fit between that purpose and the information sought. Because Con-
    gress may conduct oversight investigations only with respect to
    “‘subject[s] on which legislation could be had,’” 
    id.
     (quoting Eastland v.
    U.S. Servicemen’s Fund, 
    421 U.S. 491
    , 506 (1975)), Congress may not
    conduct such investigations for the purpose of reviewing the discharge of
    functions exclusively entrusted to the President by the Constitution. See,
    e.g., Assertion of Executive Privilege with Respect to Clemency Decision,
    
    23 Op. O.L.C. 1
    , 2 (1999) (Reno, Att’y Gen.) (“Clemency Decision”). 1 It
    follows that the activities of White House advisers are less likely than the
    activities of the departments’ and agencies’ staffs to involve matters
    within Congress’s oversight authority.
    Even when Congress operates within the appropriate scope of its over-
    sight authority, the Constitution places additional separation of powers
    constraints on inquiries directed at the White House. The Supreme Court
    1  This memorandum addresses Congress’s authority to investigate in furtherance of its
    power to legislate. See McGrain v. Daugherty, 
    273 U.S. 135
    , 175 (1927). We do not
    consider Congress’s parallel authority to obtain the information necessary to the discharge
    of its other powers, such as the House’s power to impeach, although we have recognized
    that similar principles apply in those areas. See, e.g., Exclusion of Agency Counsel from
    Congressional Depositions in the Impeachment Context, 43 Op. O.L.C. __, at *3 (Nov. 1,
    2019) (recognizing “that a congressional committee must likewise make a showing of
    need that is sufficient to overcome [executive] privilege in connection with an impeach-
    ment inquiry”); Letter for Pat A. Cipollone, Counsel to the President, from Steven A.
    Engel, Assistant Attorney General, Office of Legal Counsel at 2 (Nov. 3, 2019) (recogniz-
    ing that the immunity of certain presidential advisers from compelled congressional
    testimony “applies in an impeachment inquiry just as it applies in a legislative oversight
    inquiry”).
    2
    Congressional Oversight of the White House
    has recognized the importance of “the Executive Branch’s interests in
    maintaining the autonomy of [the Presidency] and safeguarding the confi-
    dentiality of its communications.” Cheney v. U.S. Dist. Ct., 
    542 U.S. 367
    ,
    385 (2004). These concerns are particularly acute with respect to White
    House advisers. Congressional oversight directed at the White House
    must be conducted in a way that protects the ability of the White House to
    function effectively in advising and assisting the President as he carries
    out his responsibilities under the Constitution.
    Congressional inquiries are also constrained by the heightened confi-
    dentiality interests in White House communications. See 
    id.
     At the core of
    those interests is the presidential communications component of executive
    privilege, which covers many White House communications involving
    presidential decision-making. Congressional inquiries directed to the
    White House must take account of the presumptive application of execu-
    tive privilege to White House communications, as well as the President’s
    interests in autonomy and independence. Even when the White House
    may have relevant information, these separation of powers and privilege
    concerns weigh in favor of Congress seeking available information first
    from the departments and agencies before proceeding with White House
    requests. 2
    This memorandum proceeds in four Parts. Part I describes the devel-
    opment of the White House as an organization and its central role in
    advising and assisting the President. Part II discusses the scope of con-
    gressional oversight authority and the limits on that authority as it applies
    to matters related to the discharge of the President’s constitutional func-
    tions. Part III explains that when Congress directs its oversight requests to
    the White House, the constitutionally mandated “accommodation process”
    should take into account the limitations imposed on those requests by
    separation of powers principles and the heightened executive privilege
    interests attending the communications of the White House.
    2 Although this memorandum addresses the EOP components whose principal function
    is to advise and assist the President, many of the principles discussed here would apply as
    well to so-called “dual hat” presidential advisers in other components who “exercise
    substantial independent authority or perform other functions in addition to advising the
    President.” In re Sealed Case, 
    121 F.3d 729
    , 752 (D.C. Cir. 1997). To the extent that
    Congress directs oversight efforts at activities implicating the advising “hat” of those
    officials, many of the same principles governing oversight would apply.

    45 Op. O.L.C. __ (Jan. 8, 2021)
    Finally, Part IV assesses the mechanisms for enforcing congressional
    subpoenas and discusses legal issues commonly raised by congressional
    subpoenas directed to White House staff. Historically, Congress has had
    no shortage of ways to use its powers to press executive branch officials
    to negotiate and to comply with appropriate informational demands.
    Although congressional committees have recently sued to enforce several
    subpoenas against executive officials, those lawsuits lack a foundation in
    our Nation’s history and fall outside the constitutional and statutory
    jurisdiction of the federal courts. Congress and the Executive Branch have
    traditionally worked out their disputes through negotiation and compro-
    mise, and the Department of Justice believes that those time-tested meth-
    ods are the appropriate means for resolving disputes over congressional
    information requests, no matter whether directed at the White House or
    the departments and agencies within the Executive Branch.
    I. Historical Background
    Article II of the Constitution establishes a unitary Executive Branch
    headed by the President, and it assigns to him an array of important func-
    tions, including responsibility for the Nation’s foreign relations, military
    affairs, and law enforcement. See Seila Law LLC v. Consumer Fin. Prot.
    Bureau, 
    140 S. Ct. 2183
    , 2197 (2020) (“The entire ‘executive Power’
    belongs to the President alone.”); Nixon v. Adm’r of Gen. Servs., 
    433 U.S. 425
    , 550–51 (1977) (Rehnquist, J., dissenting) (“[T]he President is made
    the sole repository of the executive powers of the United States, and the
    powers entrusted to him as well as the duties imposed upon him are awe-
    some indeed.”). It is no surprise that, in a “world of extraordinary admin-
    istrative complexity and near-incalculable presidential responsibilities,”
    Presidents have consistently and increasingly turned to the “assistance of
    close aides” in the White House to carry out their duties. Elena Kagan,
    Presidential Administration, 
    114 Harv. L. Rev. 2245
    , 2273 (2001).
    The White House’s modern organizational form traces to the EOP’s
    creation in 1939 as “an institutional response to needs felt by every occu-
    pant of the Oval Office . . . . [T]hese were, and remain, needs for advice
    and assistance.” Harold C. Relyea, The Executive Office Concept, in The
    Executive Office of the President: A Historical, Biographical, and Biblio-
    graphical Guide 4 (Harold C. Relyea ed., 1997). As one leading scholar
    4
    Congressional Oversight of the White House
    put it a decade after its establishment, “[t]he creation of the Executive
    Office of the President was a milestone in the history of the Presidency.”
    George A. Graham, The Presidency and the Executive Office of the Presi-
    dent, 12 J. Pol. 599, 603 (1950); see also Wayne Coy, Federal Executive
    Reorganization Re-examined: Basic Problems, 40 Am. Pol. Sci. Rev.
    1124, 1131–32 (1946) (“[T]he largest step toward enabling the President
    to ‘take care’ of the effective operation of the administrative system
    occurred in 1939, with the establishment of the Executive Office of the
    President.”).
    Long before the EOP’s establishment, Presidents received confidential
    advice and assistance from individuals other than department and agency
    heads. President Jackson sought help from a group of informal advisers
    known as the “Kitchen Cabinet,” which “performed most of the functions
    of a modern staff, serving his personal and political needs.” Richard B.
    Latner, The Kitchen Cabinet and Andrew Jackson’s Advisory System, 65
    J. Am. Hist. 367, 379 (1978). Historians have characterized this group of
    informal advisers “as an early prototype of the President’s White House
    staff, a group of personal aides providing the President with a variety of
    services.” Id. at 378; see also id. (noting that Jackson’s informal advisers
    shared his “perspective in overseeing the general direction of his admin-
    istration, instead of the more limited perspective of department heads”).
    The tradition of Jackson-style kitchen cabinets continued for nearly a
    century: “John Tyler had his ‘Virginia Schoolmasters’; Grover Cleveland
    maintained a ‘Fishing Cabinet’; Teddy Roosevelt sported the ‘Tennis
    Cabinet’; Warren Harding encouraged a ‘Poker Cabinet’; [and] Herbert
    Hoover instituted a ‘Medicine Ball Cabinet.’” Relyea, The Executive
    Office Concept at 43.
    During the 1920s, Congress considered several proposals to more for-
    mally establish the “administrative machinery” needed “to enable the
    President to discharge his managerial duties.” Edward H. Hobbs, An
    Historical Review of Plans for Presidential Staffing, 21 L. & Contemp.
    Probs. 663, 670 (1956). Although these initial proposals were not adopted,
    the advent of the New Deal spurred lasting action. As the administrative
    state dramatically expanded, President Franklin D. Roosevelt realized that
    he needed more staff to enable him to carry out his mounting responsibili-
    ties. In early 1936, he established a three-member committee charged with
    “investigat[ing] and report[ing]” upon “the organization for the perfor-
    5
    45 Op. O.L.C. __ (Jan. 8, 2021)
    mance of the duties imposed upon the President in exercising the execu-
    tive power vested in him by the Constitution of the United States.” Presi-
    dent’s Committee on Administrative Management, Administrative Man-
    agement in the Government of the United States 2 (1937) (“Brownlow
    Report”). The President’s Committee on Administrative Management,
    more commonly known as the Brownlow Committee after its chair, “sur-
    veyed the landscape immediately after the spate of New Deal reforms,
    [and] found a President who although ‘now ha[ving] popular responsibil-
    ity’ for the ‘direction and control of all departments and agencies of the
    Executive Branch . . . [was] not equipped with adequate legal authority or
    administrative machinery to enable him to exercise it.’” Kagan, Presiden-
    tial Administration, 114 Harv. L. Rev. at 2275.
    The Brownlow Committee “drafted a blueprint for an administrative
    staff agency, which [it] labeled the Executive Office.” Hobbs, Plans for
    Presidential Staffing, 21 L. & Contemp. Probs. at 674. The Committee’s
    final report recommended that Congress “[e]xpand the White House
    staff so that the President may have a sufficient group of able assistants
    in his own office to keep him in closer and easier touch with the wide-
    spread affairs of administration and to make a speedier clearance of the
    knowledge needed for executive decision.” Brownlow Report at 46.
    Stressing the urgent need for reform, the Committee included in its
    report a warning: “The President needs help. His immediate staff assis-
    tance is entirely inadequate.” Id. at 5. 3
    President Roosevelt strongly endorsed the Committee’s recommenda-
    tions. He stated that “[t]he plain fact is that the present organization and
    equipment of the Executive Branch of the Government defeat the Consti-
    tutional intent that there be a single responsible Chief Executive to coor-
    dinate and manage the departments and activities in accordance with the
    laws enacted by the Congress.” A Recommendation for Legislation to
    Reorganize the Executive Branch of the Government (Jan. 12, 1937),
    5 Pub. Papers of Pres. Franklin D. Roosevelt 668, 670 (1938).
    3 Louis Brownlow later recounted that the EOP’s mission as contemplated by his
    Committee was to ensure that the President could “control the policies of his departments,
    while leaving to the head of each department the decisions which are peculiar to its
    activity and the work incidental thereto.” Louis Brownlow, The Executive Office of the
    President: A General View, 1 Pub. Admin. Rev. 101, 104 (1941).
    6
    Congressional Oversight of the White House
    Congress authorized President Roosevelt to establish the EOP under the
    Reorganization Act of 1939, Pub. L. No. 76-19, 
    53 Stat. 561
    ; soon there-
    after, he issued Reorganization Plan No. 1, which became effective in July
    1939, 
    4 Fed. Reg. 2727
    , 
    53 Stat. 1423
    . President Roosevelt implemented
    the reorganization plan by executive order, organizing the EOP into five
    divisions, each charged with a distinct mission. Notably, the White House
    Office would “serve the President in an intimate capacity in the perfor-
    mance of the many detailed activities incident to his immediate office.”
    Exec. Order No. 8248, 
    4 Fed. Reg. 3864
    , 3864 (Sept. 8, 1939). The Order
    provided that presidential assistants would hold “no authority over anyone
    in any department or agency” and should “[i]n no event . . . be interposed
    between the President and the head of any department or agency.” 
    Id.
    EOP officials soon came to take a leading role in developing and coor-
    dinating policy recommendations for the President. Within its first dec-
    ade, the EOP expanded to include entities specifically created for those
    purposes. The Council of Economic Advisers, for example, was estab-
    lished in the EOP in 1946 to “analyze and interpret economic develop-
    ments” and “formulate and recommend national economic policy to
    promote full employment, production, and purchasing power under free
    competitive enterprise.” Employment Act of 1946, Pub. L. No. 79-304,
    § 4(a), 
    60 Stat. 23
    , 24. A year later, the National Security Council was
    created to “advise the President with respect to the integration of domes-
    tic, foreign, and military policies relating to the national security so as to
    enable the military services and the other departments and agencies of the
    Government to cooperate more effectively in matters involving the na-
    tional security.” National Security Act of 1947, Pub. L. No. 80-253,
    § 101(a), 
    61 Stat. 495
    , 496. 4 By the end of the Truman Administration,
    the EOP had grown to eleven principal units. Harold C. Relyea, Cong.
    Research Serv., 98-606 GOV, The Executive Office of the President: An
    Historical Overview 9 (updated Nov. 26, 2008).
    As the White House developed as an organization, all three branches of
    government recognized that it should be viewed differently from the
    departments and agencies of the Executive Branch. With respect to con-
    gressional oversight specifically, in the 1970s Assistant Attorneys General
    4 The National Security Council formally became an EOP component upon the adop-
    tion of Reorganization Plan No. 4 of 1949, 
    63 Stat. 1067
    .
    7
    45 Op. O.L.C. __ (Jan. 8, 2021)
    William Rehnquist and Antonin Scalia, among others, recognized that the
    President’s immediate White House advisers must be treated differently
    from officials of the departments and agencies when Congress seeks their
    testimony. See Memorandum for John D. Ehrlichman, Assistant to the
    President for Domestic Affairs, from William H. Rehnquist, Assistant
    Attorney General, Office of Legal Counsel, Re: Power of Congressional
    Committee to Compel Appearance or Testimony of “White House Staff ”
    (Feb. 5, 1971); Letter for Phillip E. Areeda, Counsel to the President,
    from Antonin Scalia, Assistant Attorney General, Office of Legal Counsel
    (Sept. 25, 1974); see also infra Part IV.B.
    Congress and the federal courts similarly recognized the need to treat
    the President’s inner circle of advisers differently under other federal
    laws. “Article II not only gives the President the ability to consult with his
    advisers confidentially, but also, as a corollary, it gives him the flexibility
    to organize his advisers and seek advice from them as he wishes.” Ass’n
    of Am. Physicians & Surgeons, Inc. v. Clinton, 
    997 F.2d 898
    , 909 (D.C.
    Cir. 1993). Thus, although the Freedom of Information Act (“FOIA”) by
    its terms applies to the EOP, 
    5 U.S.C. § 552
    (f )(1), the Supreme Court
    held that Congress did not include “‘the President’s immediate personal
    staff or units in the Executive Office whose sole function is to advise and
    assist the President.’” Kissinger v. Reporters Comm. for Freedom of the
    Press, 
    445 U.S. 136
    , 156 (1980) (quoting H.R. Rep. 93-1380, at 15 (1974)
    (Conf. Rep.)). Federal courts have accordingly limited FOIA to exclude
    various EOP components, making this determination by considering “how
    close operationally the [component] is to the President, what the nature of
    its delegation from the President is, and whether it has a self-contained
    structure.” Meyer v. Bush, 
    981 F.2d 1288
    , 1293 (D.C. Cir. 1993); see also,
    e.g., Judicial Watch, Inc. v. U.S. Secret Serv., 
    726 F.3d 208
     (D.C. Cir.
    2013) (holding that Secret Service logs of visitors to such advise-and-
    assist EOP offices are not “agency records” for purposes of FOIA).
    Congress similarly recognized that the President should have plenary
    discretion when it comes to hiring, paying, and organizing certain White
    House staff. In 1978, Congress authorized the President “to appoint and
    fix the pay of employees in the White House Office without regard to any
    other provision of law.” Pub. L. No. 95-570, 
    92 Stat. 2445
    , 2445 (codified
    at 
    3 U.S.C. § 105
    (a)). As this Office later observed, that statute “reflect[s]
    Congress’s judgment that the President should have complete discretion
    8
    Congressional Oversight of the White House
    in hiring staff with whom he interacts on a continuing basis.” Applicabil-
    ity of the Presidential Records Act to the White House Usher’s Office, 
    31 Op. O.L.C. 194
    , 197 (2007). As in the FOIA context, Congress thus
    viewed the advise-and-assist components of the White House as not only
    different from the departments and agencies, but also different from the
    other components of the EOP. See Citizens for Responsibility & Ethics in
    Wash. v. Office of Admin., 
    566 F.3d 219
    , 223 (D.C. Cir. 2009). Congress
    has continued to recognize that distinction up to the present day. See, e.g.,
    Presidential and Federal Records Act Amendments of 2014, Pub. L. No.
    113-187, § 2(e), 
    128 Stat. 2003
    , 2006–07 (codified at 
    44 U.S.C. § 2209
    )
    (prohibiting “the immediate staff of the President” and any “unit or indi-
    vidual of the Executive Office of the President whose function is to advise
    and assist the President” from sending presidential records using non-
    official electronic message accounts).
    The White House continues to play a unique role in the Executive
    Branch, providing the President with close and confidential advice and
    assistance on a daily basis. The White House acts as the President’s
    primary information-gathering and policy-development arm, and serves as
    “something of a central nervous system of the executive branch. . . . [It] is
    a ‘force multiplier.’ Without it, the President would be greatly weakened
    in his struggle to instantiate his preferences within the executive branch.”
    Saikrishna B. Prakash, Fragmented Features of the Constitution’s Unitary
    Executive, 
    45 Willamette L. Rev. 701
    , 714, 716 (2009). This memoran-
    dum opinion’s remaining Parts explain how the White House’s special
    status affects congressional oversight.
    II. Scope of Congressional Oversight Authority
    Although “Congress has no enumerated constitutional power to conduct
    investigations or issue subpoenas,” each House has implied authority to
    secure the information “needed” to legislate. Mazars, 140 S. Ct. at 2031
    (internal quotation marks omitted); McGrain v. Daugherty, 
    273 U.S. 135
    ,
    160–61 (1927). Each House may “make investigations and exact testimo-
    ny, to the end that it may exercise its legislative function advisedly and
    effectively.” McGrain, 
    273 U.S. at 161
    ; see also Scope of Congressional
    Oversight and Investigative Power with Respect to the Executive Branch,
    
    9 Op. O.L.C. 60
    , 60 (1985) (“Scope of Congressional Oversight ”) (“It is
    9
    45 Op. O.L.C. __ (Jan. 8, 2021)
    beyond dispute that Congress may conduct investigations in order to
    obtain facts pertinent to possible legislation and in order to evaluate the
    effectiveness of current laws.”). The House and Senate typically exercise
    their investigative functions through delegations to committees, each of
    which has jurisdiction over identified legislative subjects and agencies.
    The investigative authority of each committee is bounded by its subject
    matter jurisdiction, as identified by the rules and resolutions of the rele-
    vant congressional chamber.
    Congress’s authority to investigate in furtherance of its power to legis-
    late has come to be known as its “oversight” authority, but that shorthand
    term does not imply a general authority to review the actions of the Exec-
    utive Branch. Congress may direct the departments and agencies through
    the enactment of appropriate legislation, but the Constitution does not
    otherwise confer on Congress or its committees an authority to “oversee”
    or direct the Executive Branch in the conduct of its assigned duties and
    responsibilities under Article II. Rather, because Congress enjoys an
    implied power of investigation that “is ‘justified solely as an adjunct to
    the legislative process,’ it is subject to several limitations.” Mazars, 140
    S. Ct. at 2031 (quoting Watkins, 
    354 U.S. at 197
    ). Two of these limita-
    tions have particular significance for congressional oversight of the White
    House. First, because a congressional oversight request “is valid only if it
    is ‘related to, and in furtherance of, a legitimate task of the Congress,’” it
    “must serve a ‘valid legislative purpose.’” 
    Id.
     (quoting Watkins, 
    354 U.S. at 187
    ; Quinn v. United States, 
    349 U.S. 155
    , 161 (1955)). Second, and
    relatedly, the scope of oversight authority is limited to subjects “on which
    legislation could be had,” McGrain,

    , and therefore Con-
    gress “cannot inquire into matters which are within the exclusive province
    of one of the other branches of the Government,” Barenblatt v. United

    5 Congressional oversight authority may encompass inquiries into the Executive
    Branch’s use of appropriated funds with respect to statutory programs as well as inquiries
    relevant to future appropriations. However, as Barenblatt makes clear, the fact that the
    President or the federal courts may rely upon appropriated funds to carry out their activi-
    ties does not mean that everything they do falls within the scope of the oversight authori-
    ty. Otherwise, no matter would fall within the “exclusive province of one of the other
    branches of the Government.” Barenblatt,

    Congressional Oversight of the White House
    A. Legitimate Legislative Purpose
    Congress may conduct investigations only for legitimate legislative
    purposes. This Office has long counseled that “a threshold inquiry that
    should be made [by the Executive] upon receipt of any congressional
    request for information is whether the request is supported by any legiti-
    mate legislative purpose.” Response to Congressional Requests for Infor-
    mation Regarding Decisions Made Under the Independent Counsel Act,
    
    10 Op. O.L.C. 68
    , 74 (1986) (“Independent Counsel Act Requests”). As
    Assistant Attorney General William Barr explained, the Executive Branch
    need only assess its “interest in keeping [requested] information confiden-
    tial” after “it is established that Congress has a legitimate legislative pur-
    pose for its oversight inquiry” in the first place. Congressional Requests
    for Confidential Executive Branch Information, 
    13 Op. O.L.C. 153

    Request for the President’s Tax Returns Under 
    26 U.S.C. § 6103
    (f ), 43
    Op. O.L.C. __, at *21 (June 13, 2019) (“President’s Tax Returns”) (reiter-
    ating this position).
    Because Congress may obtain information only where it will advance a
    legitimate legislative purpose, the other branches of government must
    review congressional information requests to ensure that they are not
    motivated by an illegitimate purpose. As the Supreme Court recently
    explained in Trump v. Mazars:
    Congress has no “‘general’ power to inquire into private affairs and
    compel disclosures,” [McGrain, 273 U.S.] at 173–174, and “there is
    no congressional power to expose for the sake of exposure,” Wat-
    kins, 
    354 U.S. at 200
    . “Investigations conducted solely for the per-
    only investigate into those areas in which it may potentially legislate or appropriate, it
    cannot inquire into matters which are within the [Executive’s] exclusive province[.]” 
    Id.
    at 111–12 (emphasis added). Therefore, the limits placed on Congress when conducting
    oversight pursuant to its general legislative power also apply to oversight conducted
    pursuant to its appropriations authority. While Congress may, pursuant to its appropria-
    tions authority, review manpower statistics and other non-substantive data regarding the
    resources that Presidents historically invest in areas of exclusive executive authority,
    Congress lacks the authority to inquire into the Executive’s substantive decision-making
    in these areas.

    408 U.S. 665
    , 699 –700
    (1972) (a legislative committee “abuse[s] its proper function” when it
    exposes for the sake of exposure). Without these limits, the Court cau-
    tioned, “Congress could ‘exert an imperious controul’ over the Executive
    Branch and aggrandize itself at the President’s expense[.]” Mazars, 140
    S. Ct. at 2034 (quoting The Federalist No. 71, at 484 (Alexander Hamil-
    ton) (Jacob E. Cooke ed., 1961)). 6
    Although courts, in reviewing subpoenas directed at private parties,
    have traditionally deferred to Congress’s perceptions of its need for the
    information being sought, see, e.g., Barenblatt, 
    360 U.S. at 132
    , the
    Supreme Court in Mazars suggested that such a deferential approach does
    not extend to congressional subpoenas directed at the President’s personal
    information because of the separation of powers principles at stake in any
    such request, see 140 S. Ct. at 2031; see also id. at 2034–36. In such
    cases, a court must “be attentive to the nature of the evidence offered by
    Congress to establish that a subpoena advances a valid legislative pur-
    pose”; “[t]he more detailed and substantial the evidence of Congress’s
    legislative purpose, the better.” Id. at 2036. Moreover, “unless Congress
    adequately identifies its aims and explains why the President’s infor-
    mation will advance its consideration of the possible legislation,” it will
    be “impossible to conclude that a subpoena is designed to advance a valid
    legislative purpose.” Id. (internal quotation marks omitted); see also
    Watkins, 
    354 U.S. at 201
    , 205–06 (reversing a contempt charge due to,
    among other things, a “vague” and “broad” committee charter that ren-
    dered it “impossible . . . to ascertain whether any legislative purpose
    justifie[d] the disclosures sought and, if so, the importance of that infor-
    mation to the Congress in furtherance of its legislative function”).
    6 In the course of its oversight activities, Congress may “inquire into and publicize
    corruption, maladministration or inefficiency in agencies of the Government.” Watkins,
    
    354 U.S. at
    200 n.33. It may not, however, conduct oversight solely for the purpose of
    making information public. The Supreme Court has made clear that Congress “may only
    investigate into those areas in which it may potentially legislate or appropriate,” Baren-
    blatt, 
    360 U.S. at 111
    , and transmitting information “to inform the public . . . is not a part
    of the legislative function,” Hutchinson v. Proxmire, 
    443 U.S. 111
    , 133 (1979).
    12
    Congressional Oversight of the White House
    The Supreme Court’s review in Mazars of a House committee’s pursuit
    of the President’s financial information was consistent with how the
    Executive Branch has reviewed similar requests from Congress directed at
    the Executive Branch. Although the Executive Branch should seek to
    accommodate legitimate requests for information concerning the depart-
    ments and agencies, this Office has advised that such accommodation may
    not be required where congressional committees’ requests appear to fall
    outside their delegated legislative jurisdiction or lack a legitimate legisla-
    tive purpose.
    For instance, shortly before the Mazars decision, we concluded, based
    on reasoning similar to Mazars, that a request from the House Ways and
    Means Committee to the Department of the Treasury for the President’s
    tax returns was not supported by a legitimate legislative purpose. Presi-
    dent’s Tax Returns, 43 Op. O.L.C. __, at *3. Although the committee
    sought records similar to those at issue in Mazars, the Chairman proffered
    a different reason for the request, claiming that the committee sought to
    evaluate the Internal Revenue Service’s practice of auditing Presidents’
    tax returns. Id. at *2, *26–27. We advised that executive branch officials
    were not obliged simply to accept the committee’s proffered legislative
    purpose at face value, but instead must “examine the objective fit between
    that purpose and the information sought, as well as any other evidence
    that may bear upon the Committee’s true objective.” Id. at *17; see also
    id. at *20 (noting the Executive Branch’s obligation to “confirm[] the
    legitimacy of an investigative request,” especially “when deferring to the
    request would effectively surrender the Executive’s obligations to a
    Member of Congress”). In that case, the Chairman and other House lead-
    ers had made numerous public statements suggesting that the request was
    aimed at publicly exposing the President’s tax returns, so “[n]o one could
    reasonably believe that the Committee [sought] six years of President
    Trump’s tax returns because of a newly discovered interest in legislating
    on the presidential-audit process.” Id. at *16–17. We also stressed that the
    institutional reasons that have sometimes led courts to defer to Congress’s
    stated legislative purpose in cases involving private parties do not apply
    to the Executive Branch, “which operates as a politically accountable
    check on the Legislative Branch.” Id. at *25. We concluded that the
    Chairman’s stated legislative purpose for his request for the President’s
    13
    45 Op. O.L.C. __ (Jan. 8, 2021)
    tax returns “blink[ed] reality” and was “pretextual,” id. at *16, and there-
    fore was not legitimate.
    This Office similarly questioned the legislative purpose underlying
    three House committees’ joint request for documents related to American
    foreign and defense policy with respect to Ukraine. There, the three com-
    mittees had announced an investigation into the impeachment of the
    President, even though the full House had not delegated any such investi-
    gative jurisdiction to any of them. House Committees’ Authority to Inves-
    tigate for Impeachment, 44 Op. O.L.C. __, at *47–49 (Jan. 19, 2020)
    (“Authority to Investigate for Impeachment ”). In view of this basic legal
    defect in the requests, see id., the committees supplemented them by
    claiming that they fell within their “oversight and legislative jurisdiction.”
    Id. at *8, *47 (internal quotation marks omitted).
    We concluded that this attempt to justify the request did not establish a
    legitimate legislative purpose, even though some of the requested materi-
    als might well have fallen within the oversight jurisdiction of one or more
    of the committees. The committee chairs had “made clear” in their official
    correspondence “that the committees were interested in the requested
    materials to support an investigation into the potential impeachment of the
    President, not to uncover information necessary for potential legislation
    within their respective areas of legislative jurisdiction.” Id. at *48. We
    explained that “[t]he Executive Branch need not presume that [a legisla-
    tive] purpose exists or accept a makeweight assertion of legislative juris-
    diction.” Id. at *47 (internal quotation marks omitted). We thus found that
    the committee chairmen were “seeking to do precisely what they said—
    compel the production of information to further an impeachment inquiry.”
    Id. at *48. The inquiry therefore was made not to advance a legitimate
    legislative purpose, but instead to further an impeachment investigation
    that had not been authorized at the time the subpoenas were issued. Id. at
    *48–49.
    We also emphasized the importance of committee jurisdiction, noting
    that “[a] congressional committee’s ‘right to exact testimony and to call
    for the production of documents’ is limited by the ‘controlling charter’ the
    committee has received from the House.” Id. at *2 (quoting United States
    v. Rumely, 
    345 U.S. 41
    , 44 (1953)); see also 
    id.
     at *18–19 (discussing the
    committee jurisdiction requirement in the oversight and impeachment
    contexts); Watkins, 
    354 U.S. at 206
     (“Plainly [the House’s] committees
    14
    Congressional Oversight of the White House
    are restricted to the missions delegated to them . . . . No witness can be
    compelled to make disclosures on matters outside that area.”).
    We think that the separation of powers principles described in Mazars
    and our recent opinions guide the appropriate approach to congressional
    oversight requests directed at the White House, which inherently raise
    separation of powers concerns. “[I]n assessing whether a subpoena di-
    rected” at the White House “is related to, and in furtherance of, a legiti-
    mate task of Congress,” the White House “must perform a careful analysis
    that takes adequate account of the separation of powers principles at
    stake, including both the significant legislative interests of Congress and
    the unique position of the President.” Mazars, 140 S. Ct. at 2035 (internal
    quotation marks omitted). Although Mazars addressed a subpoena that
    sought the President’s personal financial information, there is no reason to
    think that a lesser standard would apply to oversight requests directed at
    the White House and its staff—requests that bear even more closely upon
    interests of confidentiality and the autonomy of the Executive Branch.
    The Court made clear that “congressional subpoenas for the President’s
    information unavoidably pit the political branches against one another,”
    id. at 2034, and therefore, all such requests necessarily raise separation of
    powers concerns. See also id. at 2030 (describing certain congressional
    requests for official documents as seeking “the President’s information”).
    And the case for closely scrutinizing such requests is even stronger where
    it is not, as in Mazars, a court that is evaluating the request, but instead
    the Executive Branch during the constitutionally required accommodation
    process—one purpose of which is to provide a process for the Executive
    Branch to check an implied investigative power that otherwise has limited
    counterweights. See President’s Tax Returns, 43 Op. O.L.C. __, at *25–
    26; see also infra Part III.C (discussing the accommodation process).
    In such instances, we have advised that Congress may be expected to
    clearly articulate its legislative purpose, and the Executive Branch may
    independently review the proffered purpose. In considering a committee’s
    legislative purpose, the White House should “be attentive to the nature of
    the evidence offered by Congress to establish that a subpoena advances a
    valid legislative purpose.” Mazars, 140 S. Ct. at 2036. “The more detailed
    and substantial the evidence of Congress’s legislative purpose, the better.”
    Id. The White House may fairly expect that the committee will provide a
    statement that “adequately identifies its aims and explains why the Presi-
    15
    45 Op. O.L.C. __ (Jan. 8, 2021)
    dent’s information will advance its consideration of the possible legisla-
    tion.” Id. In reviewing such a statement, the White House may take into
    account all relevant facts and circumstances in ensuring that the congres-
    sional request serves a legitimate legislative purpose within the appropri-
    ate authority of the requesting committee.
    B. Exclusive Executive Functions
    Because congressional requests for information must “concern[] a sub-
    ject on which legislation could be had,” U.S. Servicemen’s Fund, 
    421 U.S. at 506
     (internal quotation marks omitted), Congress may not conduct
    oversight of the President’s discharge of his exclusive constitutional
    authority. “Since Congress may only investigate into those areas in which
    it may potentially legislate or appropriate, it cannot inquire into matters
    which are within the exclusive province of one of the other branches of
    the Government.” Barenblatt, 
    360 U.S. at
    111−12; see also Scope of
    Congressional Oversight, 9 Op. O.L.C. at 62 (congressional oversight
    authority does not extend to “functions fall[ing] within the Executive’s
    exclusive domain”). Congressional requests to the White House often run
    into this limitation to the extent they are directed at the President’s exer-
    cise of his constitutional, rather than statutory, authorities.
    This Office has observed that “[t]he Constitution assigns a variety of
    powers exclusively to the President” and “Congress may not intrude upon
    the President’s exercise of [those] exclusive powers.” Letter for Andrew
    Fois, Assistant Attorney General, Office of Legislative Affairs, from Ran-
    dolph D. Moss, Deputy Assistant Attorney General, Office of Legal
    Counsel, Re: Inspector General for the Executive Office of the President
    at 3 (July 24, 1996) (advising that proposed legislation to establish an
    inspector general for the EOP raised serious constitutional concerns). As
    we explained, “where the President is exercising, or has exercised, exclu-
    sive constitutional authority, Congress is wholly without authority to
    impose [disclosure] requirements on the President or the President’s
    advisors.” Id. Because Congress may not legislate with respect to the
    President’s discharge of his exclusive constitutional functions, it similarly
    may not seek information from White House staff concerning the deci-
    sion-making process in connection with the President’s performance of
    those functions in particular matters.
    16
    Congressional Oversight of the White House
    Attorney General Janet Reno drew this line in advising President Clin-
    ton with respect to a congressional subpoena seeking predecisional docu-
    ments relating to a grant of clemency. The President’s clemency decision,
    which is rooted in the pardon power, is a quintessential example of an
    exclusive executive power. See Schick v. Reed, 
    419 U.S. 256
    , 266 (1974)
    (the pardon power “flows from the Constitution . . . and . . . cannot be
    modified, abridged, or diminished by the Congress”). Attorney General
    Reno advised that Congress lacked the authority to subpoena the docu-
    ments in question, because “[t]he granting of clemency pursuant to the
    pardon power is unquestionably an exclusive province of the executive
    branch,” and thus “[a] compelling argument can be made . . . that Con-
    gress has no authority whatsoever to review a President’s clemency deci-
    sion.” Clemency Decision, 23 Op. O.L.C. at 2. 7 Consistent with this
    conclusion, she explained, “it appears that Congress’ oversight authority
    does not extend to the process employed in connection with a particular
    clemency decision, to the materials generated or the discussions that took
    place as part of that process, or to the advice or views the President re-
    ceived in connection with a clemency decision.” Id. at 3–4. 8
    In 2007, Acting Attorney General Paul Clement cited the President’s
    exclusive constitutional powers in advising President Bush regarding an
    assertion of executive privilege with respect to internal White House
    communications concerning the possible exercise of the President’s
    7 As a formal matter, the President asserted executive privilege in declining to provide
    the subpoenaed documents, which related to the deliberations over the President’s grant of
    clemency to sixteen members of the FALN terrorist group. Letter for Dan Burton, Chair-
    man, Committee on Government Reform, U.S. House of Representatives, from Cheryl
    Mills, Deputy Counsel to the President at 1 (Sept. 16, 1999) (relying on the “vital public
    interest in assuring that the President receives candid advice from his advisors”). But the
    White House Counsel’s Office also raised the jurisdictional issue in objecting to the
    subpoena, stating that “[p]ursuant to the Constitution and the separation of powers
    doctrine, the President’s authority to grant clemency is not subject to legislative over-
    sight.” Id.
    8 This position also served as the basis for the Justice Department’s refusal the next
    year to answer certain questions posed by the House Judiciary Committee regarding a
    pending clemency petition. See Letter for Henry J. Hyde, Chairman, Committee on
    Judiciary, U.S. House of Representatives, from Robert Raben, Assistant Attorney Gen-
    eral, Office of Legislative Affairs at 2 (June 21, 2000) (“[B]ecause Congress cannot
    legislate regarding the process by which the Department assists the President on clemency
    matters, Congress’ oversight authority does not extend to that process.”).
    17
    45 Op. O.L.C. __ (Jan. 8, 2021)
    exclusive authority to nominate and to dismiss U.S. Attorneys: “[T]here is
    reason to question whether Congress has oversight authority to investigate
    deliberations by White House officials concerning proposals to dismiss
    and replace U.S. Attorneys, because such deliberations necessarily relate
    to the potential exercise by the President of an authority assigned to him
    alone.” Assertion of Executive Privilege Concerning the Dismissal and
    Replacement of U.S. Attorneys, 
    31 Op. O.L.C. 1
    , 3 (2007). As Acting
    Attorney General Clement explained:
    The Senate has the authority to approve or reject the appointment of
    officers whose appointment by law requires the advice and consent
    of the Senate (which has been the case for U.S. Attorneys since the
    founding of the Republic), but it is for the President to decide whom
    to nominate to such positions and whether to remove such officers
    once appointed. Though the President traditionally consults with
    members of Congress about the selection of potential U.S. Attorney
    nominees as a matter of courtesy or in an effort to secure their con-
    firmation, that does not confer upon Congress authority to inquire in-
    to the deliberations of the President with respect to the exercise of
    his power to remove or nominate a U.S. Attorney.
    
    Id.
    This principle limiting the scope of Congress’s oversight authority is
    consistent with the Supreme Court’s refusal to tolerate legislation that
    intrudes on the President’s exclusive constitutional powers and duties.
    Where the Constitution’s text commits a power to the President exclusive-
    ly, courts “refuse[] to tolerate any intrusion by the Legislative Branch.”
    Pub. Citizen v. Dep’t of Justice, 
    491 U.S. 440
    , 485 (1989) (Kennedy, J.,
    concurring in the judgment, joined by Rehnquist, C.J., and O’Connor, J.);
    see also Marbury v. Madison, 5 U.S. (1 Cranch) 137, 165–66 (1803) (“By
    the constitution of the United States, the President is invested with certain
    important political powers, in the exercise of which he is to use his own
    discretion, and is accountable only to his country in his political character,
    and to his own conscience.”).
    The President’s exclusive powers include the powers to pardon, to sign
    or veto legislation, to nominate and appoint officers of the United States,
    and to remove officers and other officials. See Schick, 
    419 U.S. at 266
    ;

    462 U.S. 919
    , 946–48, 957–59 (1983) (holding the legisla-

    tive veto an unconstitutional interference with President’s duties pursuant
    to the Presentment Clause); Buckley v. Valeo, 
    424 U.S. 1
    , 138–39 (1976)
    (per curiam) (“Congress’ power under [the Necessary and Proper] Clause
    is inevitably bounded by the express language of [the Appointments
    Clause],” and consequently Congress cannot provide for the appointment
    of “‘Officers of the United States’” except through a procedure that
    “comports with” the Appointments Clause); Myers, 
    272 U.S. at 161
     (“The
    authority of Congress given by the excepting clause to vest the appoint-
    ment of such inferior officers in the heads of departments” does not “ena-
    ble[] Congress to draw to itself, or to either branch of it, the power to
    remove or the right to participate in the exercise of that power. To do this
    would be . . . to infringe the constitutional principle of the separation of
    governmental powers.”). Thus, while Congress may request information
    pertaining to the broad range of matters about which it may legislate, that
    authority does not extend to authorities exclusively vested in the Presi-
    dent, including the work that the White House staff does in advising and
    assisting the President in connection with the execution of those constitu-
    tional authorities.
    The President’s exclusive authorities also include his powers in the area
    of diplomacy and national defense, although in many cases those powers
    closely abut areas in which Congress may legislate. The Constitution
    entrusts the President with the “‘vast share of responsibility for the con-
    duct of our foreign relations.’” Am. Ins. Ass’n v. Garamendi, 
    539 U.S. 396
    , 414 (2003) (quoting Youngstown Sheet & Tube Co. v. Sawyer, 
    343 U.S. 579
    , 610 (1952) (Frankfurter, J., concurring)). And that responsibil-
    ity includes the “exclusive authority to conduct diplomacy on behalf of
    the United States.” Congressionally Mandated Notice Period for With-
    drawing from the Open Skies Treaty, 44 Op. O.L.C. __, at *11 (Sept. 22,

    clusive authority to determine the time, scope, and objectives of interna-
    tional negotiations” (internal quotation marks omitted)). The President’s
    authority as Commander in Chief and Chief Executive also includes broad
    authority over the deployment and control of the military in protecting
    American persons and interests abroad. See, e.g., Training of British
    Flying Students in the United States, 40 Op. Att’y Gen. 58, 61–62 (1941)

    has consistently asserted the President’s exclusive authority in these areas,
    and the Supreme Court has endorsed those principles. 9
    At the same time, Congress also has overlapping authority to legislate
    in matters touching upon foreign affairs and the national defense. Con-

    tion 8, with respect to foreign trade; the raising, supporting, and regula-
    tion of the armed forces; and the declaration of war, among other powers.
    Congress’s legislative authority in these areas provides a basis for seeking
    information in connection with these areas, and such oversight requests
    may sometimes reach the White House.

    Congressional Oversight of the White House
    We have previously advised on these areas of exclusive and overlap-
    ping authority in connection with congressional oversight requests related
    to the protection of classified information. The Supreme Court has ex-
    plained that the President may “classify and control access to information
    bearing on national security and . . . determine whether an individual is
    sufficiently trustworthy to occupy a position in the Executive Branch that
    will give that person access to such information[.]” Dep’t of the Navy v.
    Egan, 
    484 U.S. 518
    , 527 (1988). This exclusive power primarily derives
    from his constitutional authority as “‘Commander in Chief of the Army
    and Navy of the United States,’” 
    id.
     (quoting U.S. Const. art. II, § 2,
    cl. 1), and “exists quite apart from any explicit congressional grant,” id.
    Although Congress does not “entirely lack[] authority to legislate in a
    manner that touches upon disclosure of classified information,” it cannot
    intrude—through legislation or oversight—upon the President’s control
    over national security information. Security Clearance Adjudications by
    the DOJ Access Review Committee, 
    35 Op. O.L.C. 86
    , 95–96 (2011); see
    The Department of Defense’s Authority to Conduct Background Investiga-
    tions for Its Personnel, 42 Op. O.L.C. __, at *9 (Feb. 7, 2018) (“while
    Congress is not entirely disabled from participating in the system for
    protecting classified information, Congress may not impair the President’s
    control over national security information”).
    In summary, because Congress’s oversight authority extends only to
    those subjects “on which legislation could be had,” McGrain, 
    273 U.S. at 177
    , the Executive Branch may properly review an oversight request
    directed at the White House to evaluate whether the request is directed at
    the discharge of an exclusive constitutional authority of the President or
    instead concerns a subject about which Congress may legislate.
    III. Constitutional Limits on
    Congressional Oversight of the White House
    Even when a congressional inquiry advances a legitimate legislative
    purpose, the separation of powers imposes other constraints on oversight
    of the White House. The accommodation process requires that “each
    branch . . . take cognizance of an implicit constitutional mandate to seek
    optimal accommodation through a realistic evaluation of the needs of the
    conflicting branches in the particular fact situation.” United States v. Am.
    21
    45 Op. O.L.C. __ (Jan. 8, 2021)
    Tel. & Tel. Co. (“AT&T ”), 
    567 F.2d 121
    , 127 (D.C. Cir. 1977). As dis-
    cussed below, the President’s strong interests in the independence and
    autonomy of his office, as well as the confidentiality of his communica-
    tions, justify corresponding restrictions on oversight of the White House.
    Congressional requests for information from the White House are con-
    strained by “the Executive Branch’s interests in maintaining the autonomy
    of [the] office [of the President] and safeguarding the confidentiality of its
    communications.” Cheney, 
    542 U.S. at 385
    . In addition, oversight di-
    rected at the White House implicates heightened executive branch confi-
    dentiality interests, which are particularly strong with respect to White
    House communications. Accordingly, when oversight involves the White
    House, congressional committees and the White House must work to
    respect these constraints while accommodating the committees’ legitimate
    information needs. These considerations mean that oversight requests
    directed to the White House are typically the exception, rather than the
    norm. Congress should generally seek information from the departments
    and agencies first before turning to the White House, and oversight re-
    quests to the White House must be tailored to accommodate the Presi-
    dent’s need for autonomy and confidentiality.
    A. Separation of Powers Principles
    The President is the head of a co-equal branch of government. Congress
    and the President thus “have an ongoing institutional relationship as the
    ‘opposite and rival’ political branches established by the Constitution.”
    Mazars, 140 S. Ct. at 2033–34 (quoting The Federalist No. 51, at 349
    (James Madison)). Consequently, congressional requests for information
    directed at the President and the White House are not “run-of-the-mill
    legislative effort[s]” and “differ markedly from” congressional requests
    directed toward others. Id. at 2034. The “significant separation of powers
    issues” raised by such requests “necessarily inform[]” the scope of and
    manner in which Congress may request such information. Id. at 2026,
    2033. If Congress could freely demand the President’s information, it
    would “‘exert an imperious controul’ over the Executive Branch and
    aggrandize itself at the President’s expense, just as the Framers feared.”
    Id. at 2034 (quoting The Federalist No. 71, at 484). In the same way that
    the President must respect Congress’s institutional prerogatives, Congress
    22
    Congressional Oversight of the White House
    too must conduct oversight mindful of the independence and autonomy of
    the office of the President.
    Although the Supreme Court’s opinion in Mazars discussed these prin-
    ciples in the context of congressional requests for the President’s personal
    information, these separation of powers concerns also apply to requests
    for information from White House advisers, who assist the President “on a
    daily basis in the formulation of executive policy and resolution of mat-
    ters affecting the military, foreign affairs, and national security and other
    aspects of his discharge of his constitutional responsibilities.” Testimonial
    Immunity Before Congress of the Former Counsel to the President, 43 Op.
    O.L.C. __, at *5 (May 20, 2019) (“Immunity of the Former Counsel ”)
    (internal quotation marks omitted).
    The Supreme Court recognized as much in Cheney, which addressed
    the special consideration owed to the White House in connection with
    demands for information made in a civil action. The Court held that the
    Judicial Branch must treat civil discovery requests directed at the Presi-
    dent’s senior advisers differently from discovery matters involving other
    executive branch personnel:
    This is not a routine discovery dispute. The discovery requests are
    directed to the Vice President and other senior Government officials
    who . . . give advice and make recommendations to the President.
    The Executive Branch, at its highest level, is seeking the aid of the
    courts to protect its constitutional prerogatives. . . . [S]pecial consid-
    erations control when the Executive Branch’s interests in maintain-
    ing the autonomy of its office and safeguarding the confidentiality of
    its communications are implicated. This Court has held, on more
    than one occasion, that “[t]he high respect that is owed to the office
    of the Chief Executive . . . is a matter that should inform the conduct
    of the entire proceeding, including the timing and scope of discov-
    ery,” and that the Executive’s “constitutional responsibilities and
    status [are] factors counseling judicial deference and restraint” in the
    conduct of litigation against it.
    
    542 U.S. at 385
     (citations omitted). While the purposes of congressional
    oversight and civil discovery are distinct, both involve requests from
    outside the Executive Branch. Just as separation of powers principles
    require the Judicial Branch to adjust the “timing and scope of discovery”
    23
    45 Op. O.L.C. __ (Jan. 8, 2021)
    directed at presidential advisers in civil litigation, congressional commit-
    tees and White House personnel also must tailor the timing and scope of
    their oversight accommodations in ways that respect the President’s
    interests in autonomy and confidentiality.
    In Cheney, the Supreme Court reviewed the D.C. Circuit’s denial of the
    Vice President’s petition for a writ of mandamus vacating certain discov-
    ery orders issued by a district court. The plaintiffs had sued the Vice
    President and others alleging that the President’s National Energy Policy
    Development Group had not complied with the disclosure requirements of
    the Federal Advisory Committee Act, 5 U.S.C. app. §§ 1–15. The district
    court ordered the plaintiffs to “submit a proposed discovery plan” for the
    court’s approval. Judicial Watch, Inc. v. Nat’l Energy Policy Dev. Group,
    
    219 F. Supp. 2d 20
    , 56 (D.D.C. 2002). Under the Federal Rules of Civil
    Procedure, a litigant “may obtain discovery regarding any nonprivileged
    matter that is relevant to any party’s claim or defense.” Fed. R. Civ. P.
    26(b)(1). Pursuant to this broad standard governing civil discovery, the
    plaintiffs in Cheney proposed a wide-ranging discovery plan, which called
    for the production of all documents and information concerning commu-
    nications between individual National Energy Policy Development Group
    members outside the context of group meetings, between members and
    agency personnel, and between members and non-governmental individu-
    als. The plaintiffs tried to use discovery to uncover confidential infor-
    mation concerning the deliberations of the President’s closest advisers.
    The Government objected to the plan to the extent that it sought docu-
    ments from the Vice President and White House officials and argued,
    among other things, “that in order to protect the separation of powers, the
    President should not be forced to consider the [executive] privilege ques-
    tion in response to unnecessarily broad or otherwise improper discovery.”
    See In re Cheney, 
    334 F.3d 1096
    , 1105 (D.C. Cir. 2003) (internal quota-
    tion marks omitted).
    The district court nonetheless approved the discovery plan and directed
    that the Vice President and White House officials either “fully comply
    with” the discovery requests, “file detailed and precise objections to
    particular requests,” or “identify and explain their invocations of privilege
    with particularity.” Id. at 1000 (internal quotation marks omitted). The
    Vice President petitioned the D.C. Circuit for a writ of mandamus vacat-
    ing the discovery orders on the ground that the broad requests violated the
    24
    Congressional Oversight of the White House
    separation of powers by unduly interfering with the President’s constitu-
    tional prerogatives, but the D.C. Circuit denied the petition. See id. at
    1109.
    The Supreme Court reversed and remanded for the D.C. Circuit to con-
    sider whether the discovery orders “constituted an unwarranted impair-
    ment of another branch in the performance of its constitutional duties.”
    Cheney, 
    542 U.S. at 390
    . In so holding, the Court rejected the lower
    courts’ view that executive branch interests could have been adequately
    protected by “invoking executive privilege and filing objections to the
    discovery orders with ‘detailed precision.’” 
    Id. at 377
     (quoting In re
    Cheney, 334 F.3d at 1105). The Court explained that “special considera-
    tions control” when White House staff and other high-level officials are
    the subject of civil discovery requests, and that separation of powers
    concerns might necessitate narrowing or denying requests for information
    directed to such officials before there should arise any need to consider
    invoking executive privilege. See id. at 385, 390. Because the information
    “requests [were] directed to the Vice President and other senior Govern-
    ment officials who served on the [Group] to give advice and make rec-
    ommendations to the President,” the broad discovery orders threatened to
    impinge on the Executive’s “interests in maintaining the autonomy of its
    office and safeguarding the confidentiality of its communications.” Id. at
    385. Therefore, the D.C. Circuit was obliged to consider whether allowing
    the requests to go forward would be “an unwarranted impairment” of the
    Executive Branch’s discharge of its constitutional responsibilities. Id. at
    390.
    The Court’s reasoning in Cheney, which instructs courts to consider the
    President’s interests in autonomy and confidentiality when fashioning
    orders authorizing civil discovery directed at the White House, applies
    with at least equal force to congressional oversight requests for infor-
    mation from the White House. Both congressional oversight and civil
    litigation often concern wide-ranging information requests that involve
    the production of documents and the taking of testimony. Just as civil
    litigation against the “Vice President and other senior Government offi-
    cials who . . . give advice and make recommendations to the President”
    does not entail “a routine discovery dispute,” neither may congressional
    oversight of the White House be viewed as comparable to routine over-
    sight of executive branch agencies. Cf. Immunity of the Former Counsel,
    25
    45 Op. O.L.C. __ (Jan. 8, 2021)
    43 Op. O.L.C. __, at *4 (“[T]he President’s immediate advisers are consti-
    tutionally distinct from the heads of executive departments and agen-
    cies.”). In both situations, far-reaching inquiries threaten presidential
    autonomy and confidentiality. Thus, the separation of powers concerns
    recognized in Cheney support significant limitations on the timing and
    scope of congressional oversight inquiries directed to the White House.
    If anything, the concerns underlying the Court’s decision in Cheney
    apply with even greater force to congressional inquiries. Congress is the
    President’s constitutional “rival” in a manner distinct from the Judiciary.
    Mazars, 140 S. Ct. at 2033 (internal quotation marks omitted). When
    Congress conducts oversight, a neutral decision-maker is not readily
    available to appropriately balance each party’s interests. And unlike the
    courts’ express authority to order discovery, Congress’s subpoena power
    is an implied adjunct to its legislative powers that is justified as “an
    essential and appropriate auxiliary to the legislative function.” Id. at 2031
    (quoting McGrain, 
    273 U.S. 174
    ); cf. Nat’l Fed’n of Indep. Bus. v. Sebe-
    lius, 
    567 U.S. 519
    , 559 (2012) (opinion of Roberts, C.J.) (implied powers
    under the Necessary and Proper Clause are “incidental” and cannot be
    “great substantive and independent powers” (internal quotation marks
    omitted)). A plaintiff in a civil action, moreover, may well have a greater
    need for documents and other information than a congressional committee
    conducting oversight. Congressional oversight gathers information so that
    Congress may “exercise its legislative function advisedly and effectively,”
    McGrain, 
    273 U.S. at 161
    ; see also Mazars, 140 S. Ct. at 2031–32, while
    the purpose of civil discovery is to disclose “the basic issues and facts” to
    “the fullest practicable extent,” United States v. Procter & Gamble Co.,
    
    356 U.S. 677
    , 682 (1958). As the D.C. Circuit thus has recognized, “legis-
    lative judgments normally depend more on the predicted consequences of
    proposed legislative actions and their political acceptability[] than on
    precise reconstruction of past events.” Senate Select Comm. on Presiden-
    tial Campaign Activities v. Nixon, 
    498 F.2d 725
    , 732 (D.C. Cir. 1974) (en
    banc). “[E]fforts to craft legislation involve predictive policy judgments
    that are not hampered in quite the same way when every scrap of poten-
    tially relevant evidence is not available [to Congress].” Mazars, 140 S. Ct.
    at 2036 (alterations and internal quotation marks omitted).
    Furthermore, because Congress may not conduct oversight of the Presi-
    dent’s exclusive constitutional functions, legitimate congressional over-
    26
    Congressional Oversight of the White House
    sight inquiries will almost always pertain to executive branch implemen-
    tation of statutory programs. But the departments and agencies, not the
    White House, principally administer such programs, and thus it is general-
    ly unnecessary for congressional committees to request information
    directly from the White House unless they are unable to obtain the infor-
    mation from agencies. As Mazars determined with respect to the Presi-
    dent’s personal information, to avoid unnecessary confrontation between
    the branches, “Congress may not rely on the President’s information if
    other sources could reasonably provide Congress the information it
    needs.” Id. at 2035–36. That reasoning also applies to congressional
    requests for White House information. Because congressional oversight
    needs generally may be satisfied through requests to the departments and
    agencies, requests for information about programs administered outside
    the White House should be directed there in the first instance.
    Mazars and Cheney are the latest in a line of judicial precedent recog-
    nizing the separation of powers concerns underlying litigation or related
    requests directed at the President. But the Supreme Court has long recog-
    nized that safeguarding presidential autonomy and confidentiality is
    critical to honoring the separation of powers. See Cheney, 
    542 U.S. at 385
    . This principle was first articulated in United States v. Burr, where
    Chief Justice John Marshall, sitting at trial as a Circuit Justice, stated that
    “[i]n no case of this kind would a court be required to proceed against the
    president as against an ordinary individual.” 
    25 F. Cas. 187
    , 192 (C.C. Va.
    1807) (No. 14,694). In Nixon v. Fitzgerald, 
    457 U.S. 731
     (1982), the
    Court held that a sitting or former President is absolutely immune from
    civil actions for damages arising from his official acts. Underlying this
    bright-line rule is the rationale that “[b]ecause of the singular importance
    of the President’s duties, diversion of his energies . . . would raise unique
    risks to the effective functioning of government.” 
    Id. at 751
    . 10 The Presi-
    10 The Supreme Court has held that presidential aides are generally treated differently
    from the President for purposes of immunity in civil litigation, receiving qualified im-
    munity rather than absolute immunity. Harlow, 
    457 U.S. at 809
    . But see 
    id.
     at 812 & n.19
    (acknowledging that “[f ]or aides entrusted with discretionary authority in such sensitive
    areas as national security or foreign policy, absolute immunity might well be justified to
    protect the unhesitating performance of functions vital to the national interest”). Yet that
    distinction is entirely consistent with Cheney’s holding that “special considerations” apply
    to civil discovery requests directed to White House officials and others who “give advice
    27
    45 Op. O.L.C. __ (Jan. 8, 2021)
    dent’s energies may be inappropriately diverted by congressional over-
    sight just as they may be by private litigation. See Immunity of the Former
    Counsel, 43 Op. O.L.C. __, at *5 (explaining that permitting congression-
    al committees to compel the President’s immediate advisers to testify
    would allow the committees to “harass those advisers in an effort to
    influence their conduct, retaliate for actions the committee disliked, or
    embarrass and weaken the President for partisan gain” and would force
    the advisers “to divert time and attention from their duties to the Presi-
    dent” (internal quotation marks omitted)).
    In the oversight context, the President’s interest in the White House’s
    autonomy may be compromised not only by congressional inquiries that
    distract personnel and drain critical resources, but also by the potential
    “chilling effect” such demands would have on the interactions between
    the President and his advisers. See Testimonial Immunity Before Congress
    of the Assistant to the President and Senior Counselor to the President,
    43 Op. O.L.C. __, at *2 (July 12, 2019) (“Congressional questioning of
    the President’s senior advisers would . . . undermine the independence and
    candor of executive branch deliberations.”). Intrusive congressional over-
    sight of the White House’s interaction with departments and agencies may
    cause White House staff members to conform their information-gathering
    and policy-formulation processes to the demands of Congress instead of
    the needs of the President. Yet the President needs his staff to provide him
    with frank and candid judgments to “accomplish[] [his] constitutionally
    assigned functions.” Nixon v. Adm’r of Gen. Servs., 
    433 U.S. at 443
    .
    There is little doubt that intrusive oversight inquiries could chill and
    otherwise undermine these kinds of White House staff activities. See
    Scope of Congressional Oversight, 9 Op. O.L.C. at 62 (“Congress’ power
    of inquiry must not be permitted to negate the President’s constitutional
    and make recommendations to the President.” 
    542 U.S. at 385
    . As we have explained in
    declining to apply Harlow to narrow the traditional constraints governing the congres-
    sional testimony of senior presidential advisers, “the prospect of compelled congressional
    testimony raises separation of powers concerns that are not present in a civil damages
    lawsuit brought by a private party.” Immunity of the Former Counsel, 43 Op. O.L.C. __,
    at *13. Compelled congressional testimony “threatens to subject presidential advisers to
    coercion and harassment, create a heightened impression of presidential subordination to
    Congress, and cause public disclosure of confidential presidential communications in a
    way that the careful development of evidence through a judicially monitored [proceeding]
    does not.”

    responsibility for managing and controlling affairs committed to the
    Executive Branch.”).
    Closely related to the President’s interest in securing the White House’s
    autonomy is his interest in “safeguarding the confidentiality of its com-
    munications.” Cheney, 
    542 U.S. at 385
    . The Supreme Court has made
    clear that the President’s interest in the confidentiality of his decision-
    making is a central component of the constitutional separation of powers.
    In United States v. Nixon, the Court stressed that “[a] President and those
    who assist him must be free to explore alternatives in the process of
    shaping policies and making decisions and to do so in a way many would
    be unwilling to express except privately.” 
    418 U.S. 683
    , 708 (1974).
    Although Nixon concerned a judicial demand for documents protected by
    executive privilege, this Office has long expressed the view that “[the]
    reasons for the constitutional privilege have at least as much force when it
    is Congress, instead of a court, that is seeking information.” Congression-
    al Requests, 13 Op. O.L.C. at 156. Indeed, “the prospect that predeci-
    sional deliberative communications will be disclosed to Congress is, if
    anything, more likely to chill internal debate among executive branch
    advisers than the possibility of disclosure to the judicial branch.” Memo-
    randum for Janet Reno, Attorney General, from Walter Dellinger, Assis-
    tant Attorney General, Office of Legal Counsel, Re: Congressional De-
    mands to Interview Prosecutors and Review Deliberative Documents in
    Closed Cases at 14–15 (Nov. 23, 1993). 11 Because many White House
    11   As this Office has explained more fully:
    When the Supreme Court held that the need for presidential communications in the
    criminal trial of President Nixon’s close aides outweighed the constitutional privi-
    lege, an important premise of its decision was that it did not believe that advisers
    will be moved to temper the candor of their remarks by the infrequent occasions of
    disclosure because of the possibility that such conversations will be called for in the
    context of a criminal prosecution. By contrast, congressional requests for executive
    branch deliberative information are anything but infrequent. Moreover, compared
    to a criminal prosecution, a congressional investigation is usually sweeping; its is-
    sues are seldom narrowly defined, and the inquiry is not restricted by the rules of
    evidence. Finally, when Congress is investigating, it is by its own account often in
    an adversarial position to the executive branch and initiating action to override
    judgments made by the executive branch. This increases the likelihood that candid
    advice from executive branch advisers will be taken out of context or misconstrued.

    staff members enjoy extensive access to the President, play important
    roles in developing presidential policy, and often serve as the President’s
    alter ego, the President’s interest in the confidentiality of White House
    activities must be afforded considerable weight in assessing the legitima-
    cy of an exercise of Congress’s oversight functions.
    B. Executive Privilege and White House Information
    The heightened executive privilege interests that apply to White House
    communications provide an additional basis for distinguishing oversight
    inquiries directed at the White House from oversight of departments and
    agencies. Presidents have invoked executive privilege since the earliest
    days of the Republic, and the Supreme Court has recognized the privilege
    and held it to be an implied power under the Constitution. See Nixon, 
    418 U.S. at 705, 708
    ; see also 
    id. at 711
     (“Nowhere in the Constitution . . . is
    there any explicit reference to a privilege of confidentiality, yet to the
    extent this interest relates to the effective discharge of a President’s
    powers, it is constitutionally based.”); Congressional Requests, 13 Op.
    O.L.C. at 154 (explaining that the existence of executive privilege is a
    “necessary corollary of the executive function vested in the President by
    Article II of the Constitution”). The Court has described the privilege as
    “deriv[ing] from the supremacy of each branch within its own assigned
    area of constitutional duties,” “fundamental to the operation of Govern-
    ment,” “and inextricably rooted in the separation of powers under the
    Constitution.” Nixon,

    . The privilege “safeguards the
    public interest in candid, confidential deliberations within the Executive
    Branch,” and, as a result, “information subject to executive privilege
    deserves the greatest protection consistent with the fair administration of
    justice.” Mazars, 140 S. Ct. at 2032 (internal quotation marks omitted).
    There are at least five well-recognized, and sometimes overlapping,
    components of executive privilege: national security and foreign affairs,
    law enforcement, deliberative process, attorney-client communications
    and attorney work product, and presidential communications. See At-
    tempted Exclusion of Agency Counsel from Congressional Depositions of

    clusion of Agency Counsel ”); Assertion of Executive Privilege Concerning

    92nd Cong. 420 (1971) (statement of William Rehnquist, Assistant Attor-
    ney General, Office of Legal Counsel). Generally speaking, the national
    security and foreign affairs component provides absolute protection for
    materials the release of which would jeopardize sensitive diplomatic,
    national security, or military matters, including classified information and
    diplomatic communications. 12 Similarly, the law enforcement component
    of the privilege gives the Executive Branch a near-absolute right to with-
    hold from Congress information that would compromise ongoing law
    enforcement activities. 13 Both of these components of executive privilege
    are deeply rooted in the Constitution and the Nation’s history.

    484 U.S. at 527

    Congressional inquiries to the White House more often implicate the
    deliberative process, the attorney-client communications and attorney
    work product, and particularly the presidential communications compo-
    nents of executive privilege. These components are also deeply rooted,
    and they protect from disclosure internal communications and information
    concerning presidential and other executive branch decision-making.
    They are based on the principle that the effective operation of the Execu-
    tive Branch depends on shielding deliberative communications and advice
    from disclosure. See Confidentiality of the Attorney General’s Communi-
    cations in Counseling the President, 
    6 Op. O.L.C. 481
    , 484–97 (1982)
    (“Attorney General’s Communications”).
    The deliberative process component of executive privilege “safeguards
    the public interest in candid, confidential deliberations within the Execu-
    tive Branch” and protects all executive branch documents that reflect
    advisory opinions, recommendations, and other deliberative communica-
    tions generated during governmental decision-making. Mazars, 140 S. Ct.
    at 2032; see In re Sealed Case, 
    121 F.3d 729

    also Congressional Requests, 13 Op. O.L.C. at 156–57 & n.3 (explaining
    the applicability of this component in the context of congressional re-
    quests for information). The deliberative process component is premised
    on the fact that disclosing the “communications and the ingredients of the
    decisionmaking process” would inevitably cause “injury to the quality of
    agency decisions” by inhibiting “‘frank discussion of legal or policy
    law enforcement files, it has been the policy of the executive branch throughout our
    Nation’s history to protect these files from any breach of confidentiality, except in
    extraordinary circumstances.”); Independent Counsel Act Requests, 10 Op. O.L.C. at 75–

    (citation omitted). As the Supreme Court explained in Nixon:
    [There is a] valid need for protection of communications between
    high Government officials and those who advise and assist them in
    the performance of their manifold duties; the importance of this con-
    fidentiality is too plain to require further discussion. Human experi-
    ence teaches that those who expect public dissemination of their re-
    marks may well temper candor with a concern for appearances and
    for their own interests to the detriment of the decisionmaking pro-
    cess.

    ; see also Dep’t of the Interior v. Klamath Water Users
    Protective Ass’n, 
    532 U.S. 1

    process component “rests on the obvious realization that officials will not
    communicate candidly among themselves if each remark is a potential
    item of discovery and front page news, and its object is to enhance the
    quality of agency decisions, by protecting open and frank discussion
    among those who make them” (internal quotation marks and citation
    omitted)). The deliberative process component of executive privilege
    applies especially strongly when the deliberations in question are ongo-
    ing. See Publication of a Report to the President on the Effect of Automo-
    bile and Automobile-Part Imports on the National Security, 44 Op. O.L.C.
    __, at *10–11 (Jan. 17, 2020) (“Publication of Report on Imports”). But
    the deliberative process component has certain limits: It protects predeci-
    sional and deliberative materials and typically does not “shield documents
    that simply state or explain a decision the government has already made
    or protect material that is purely factual.” Sealed Case, 121 F.3d at 737.
    Agencies may withhold factual information only to the extent it is “so
    inextricably intertwined with the deliberative sections of documents that
    its disclosure would inevitably reveal the government’s deliberations.” Id.
    The attorney-client communications and attorney work product compo-
    nent of executive privilege protects executive branch communications and
    documents that involve legal analysis, legal advice, and other attorney
    communications or work product. See Assertion of Executive Privilege
    Regarding White House Counsel’s Office Documents, 
    20 Op. O.L.C. 2
    , 3
    (1996) (Reno, Att’y Gen.) (recognizing that “[e]xecutive privilege ap-
    plies” to certain documents “because of their deliberative nature, and
    33
    45 Op. O.L.C. __ (Jan. 8, 2021)
    because they fall within the scope of the attorney-client privilege and the
    work-product doctrine”). Often, such communications will be protected
    by the deliberative process component in addition to the attorney-client
    and attorney work product component. Yet “‘the reasons for the constitu-
    tional privilege against the compelled disclosure of executive branch
    deliberations have special force when legal advice is involved,’” because
    “‘legal matters are likely to be among those on which high government
    officials most need, and should be encouraged to seek, objective, expert
    advice.’” Attorney General’s Communications, 6 Op. O.L.C. at 490 n.17

    branch officials are to execute their constitutional and statutory responsi-
    bilities, they must have access to candid and confidential legal advice and
    assistance.”).
    The presidential communications component of executive privilege,
    which is the most salient component for White House purposes, protects
    communications made in connection with presidential decision-making.
    See Nixon, 
    418 U.S. at 708
     (explaining importance of presidential com-
    munications privilege in government operations); Sealed Case, 121 F.3d
    at 746 (explaining that the “presidential [communications] privilege
    affords greater protection against disclosure” than the deliberative pro-
    cess privilege); Memorandum for the Attorney General from John M.
    Harmon, Assistant Attorney General, Office of Legal Counsel, Re: The
    Constitutional Privilege for Executive Branch Deliberations: The Dis-
    pute with a House Subcommittee over Documents Concerning the Gaso-
    line Conservation Fee at 13 (Jan. 13, 1981) (“Executive Branch Deliber-
    ations”). Although the presidential communications component applies
    only to presidential decision-making, it is broader than the deliberative
    process component in terms of the types of communications that are
    protected. All presidential communications are “presumptively privi-
    leged” and protected from disclosure, including post-decisional exchang-
    es and documents conveying purely factual information. Nixon, 
    418 U.S. at 708
    , 713–14 (explaining that a presumptive privilege applies to the
    President’s “conversations and correspondence”); see also Sealed Case,
    121 F.3d at 745 (“[U]nlike the deliberative process privilege, the presi-
    dential communications privilege applies to documents in their entirety,
    and covers final and post-decisional materials as well as pre-deliberative
    34
    Congressional Oversight of the White House
    ones.”). In addition, this component of executive privilege covers com-
    munications between the President and agencies concerning presidential
    decision-making, including communications concerning the exercise of
    statutory authority. See Publication of Report on Imports, 44 Op. O.L.C.
    __, at *7–9.
    The presidential communications component of executive privilege is
    not limited to exchanges directly involving the President. The Supreme
    Court emphasized in Nixon that the “President and those who assist him
    must be free to explore alternatives in the process of shaping policies and
    making decisions,” 
    418 U.S. at 708
     (emphasis added), and explicitly
    described the privilege as protecting communications within the Presi-
    dent’s “office,” 
    id.
     at 712–13. We have consistently recognized that for
    the President to obtain full, frank, and complete advice, the presidential
    communications component must apply to deliberations among the Presi-
    dent’s advisers and their staffs. See, e.g., Attorney General’s Communica-
    tions, 6 Op. O.L.C. at 485–86 & n.11 (explaining that the presidential
    communications privilege protects the presidential “decisionmaking
    process” and, therefore, can apply to the work of presidential advisers).
    The D.C. Circuit agreed in 1997, when it held that “communications
    made by presidential advisers in the course of preparing advice for the
    President come under the presidential communications privilege, even
    when these communications are not made directly to the President.”
    Sealed Case, 121 F.3d at 751–52. In reaching this conclusion, the court,
    echoing the Supreme Court’s analysis in Nixon, warned that “[i]f presi-
    dential advisers must assume they will be held to account publicly for all
    approaches that were advanced, considered, but ultimately rejected, they
    will almost inevitably be inclined to avoid serious consideration of novel
    or controversial approaches to presidential problems.” Id. at 750. Exclud-
    ing presidential advisers and their staffs from the presidential communica-
    tions component would hinder the President’s “access to honest and
    informed advice” and limit his “ability to explore possible policy op-
    tions.” Id. at 751. A narrower privilege would “impede . . . the presiden-
    cy,” id., and diminish the quality of presidential decisions:
    Presidential advisers do not explore alternatives only in conversa-
    tions with the President or pull their final advice to him out of thin
    air—if they do, their advice is not likely to be worth much. Rather,
    35
    45 Op. O.L.C. __ (Jan. 8, 2021)
    the most valuable advisers will investigate the factual context of a
    problem in detail, obtain input from all others with significant exper-
    tise in the area, and perform detailed analyses of several different
    policy options before coming to closure on a recommendation for the
    Chief Executive. The President himself must make decisions relying
    substantially, if not entirely, on the information and analysis sup-
    plied by advisers.
    Id. at 750. 14
    Against this backdrop, communications within the White House and
    between White House staff and other EOP components that concern
    possible presidential decision-making will normally fall under the presi-
    dential communications component of executive privilege, and not just
    the deliberative process or attorney-client communications and attorney
    work product components that apply to all government agencies and that
    are most commonly implicated when congressional committees make
    oversight requests of executive agencies. See Executive Branch Delibera-
    tions at 12 (concluding that “‘presidential’ communications . . . presuma-
    bly [include] discussions among the President’s aides and officials in the
    Executive Office of the President ” (emphasis added)). Consequently, a
    congressional request for internal White House communications and intra-
    EOP communications will frequently implicate the presidential communi-
    cations component of executive privilege. As a result, oversight directed
    at the White House will typically involve privilege interests that are, on
    the whole, considerably greater than those arising solely in the agency
    context, where other components are more commonly implicated.
    14 In Judicial Watch, Inc. v. Department of Justice, 
    365 F.3d 1108
     (D.C. Cir. 2004), the
    D.C. Circuit in dictum construed Sealed Case’s use of the phrase “White House adviser”
    when describing the scope of the presidential communications privilege as restricting the
    privilege to the President’s “immediate advisers in the Office of the President” (a compo-
    nent of the EOP also called the White House Office). 
    Id. at 1123
    ; see 
    id.
     at 1109 n.1,
    1116–17, 1123–24. This assumption misinterprets Sealed Case. Its explicit holding that
    communications by “presidential advisers” and “their staff ” made “in the course of
    preparing advice for the President come under the presidential communications privilege”
    indicates that the privilege must encompass advisers in EOP entities outside the Office of
    the President whose primary function is to advise and assist the President. See 121 F.3d at
    751–52.

    Congressional Oversight of the White House
    C. The Accommodation Process
    for Oversight of the White House
    Given the President’s interests in autonomy and confidentiality, the ac-
    commodation process will often lead to a different balance when applied
    to the White House as compared to the departments and agencies. It is
    long-standing executive branch policy that upon receipt of an authorized
    oversight request that is in furtherance of a legitimate legislative purpose,
    departments and agencies should “comply with Congressional requests for
    information to the fullest extent consistent with the constitutional and
    statutory obligations of the Executive Branch.” Memorandum for Heads
    of Executive Departments and Agencies from Ronald Reagan, Re: Proce-
    dures Governing Responses to Congressional Requests for Information
    at 1 (Nov. 4, 1982) (“Reagan Memorandum”). The manner of that com-
    pliance is determined by the operation of the accommodation process
    mandated by the Constitution, recognized by the Judicial Branch, and
    practiced by the Executive and Legislative Branches. “Historically, good
    faith negotiations between Congress and the Executive Branch have
    minimized the need for invoking executive privilege,” and “this tradition
    of accommodation” has remained “the primary means of resolving con-
    flicts between the Branches.” Id.
    The Supreme Court has also recognized that disputes over congression-
    al demands for executive documents ordinarily “have been hashed out in
    the ‘hurly-burly, the give-and-take of the political process between the
    legislative and the executive.’” Mazars, 140 S. Ct. at 2029 (quoting Exec-
    utive Privilege—Secrecy in Government: Hearings on S. 2170, S. 2378,
    and S. 2420 Before the Subcomm. on Intergovernmental Relations of the
    S. Comm. on Gov’t Operations, 94th Cong. 87 (1975) (statement of Anto-
    nin Scalia, Assistant Attorney General, Office of Legal Counsel)). Since
    the Washington Administration, the Executive Branch has resisted con-
    gressional information demands that were overly burdensome or threat-
    ened to impair “the public good.” Id. at 2029–30 (internal quotation marks
    omitted). Executive branch resistance, in turn, has often been met by
    congressional pressure, which was then followed by subsequent negotia-
    tions between the branches. In most instances, Congress and the Execu-
    tive Branch have reached a compromise in which Congress might, for
    example, narrow the scope of its request or better articulate its needs, and
    37
    45 Op. O.L.C. __ (Jan. 8, 2021)
    the Executive Branch might, for example, supply a subset of the requested
    documents, provide summaries of the information requested, or permit in
    camera review of particular documents. Id. This long-standing “tradition
    of negotiation and compromise” stands at the heart of the accommodation
    process. Id. at 2031.
    In AT&T, the D.C. Circuit discussed the constitutional foundations for
    the accommodation process. 
    567 F.2d 121
    . There, the Department of
    Justice sought to enjoin AT&T from complying with a congressional
    subpoena that the Executive Branch believed implicated highly classified
    information, the disclosure of which would be detrimental to national
    security. The D.C. Circuit declined to decide the case on the merits and
    instead mandated a “procedure giv[ing] promise of satisfying the substan-
    tial needs of both [branches].” Id. at 123. The court stated:
    The framers . . . expect[ed] that where conflicts in scope of authority
    arose between the coordinate branches, a spirit of dynamic compro-
    mise would promote resolution of the dispute in the manner most
    likely to result in efficient and effective functioning of our govern-
    mental system. . . . [E]ach branch should take cognizance of an im-
    plicit constitutional mandate to seek optimal accommodation through
    a realistic evaluation of the needs of the conflicting branches in the
    particular fact situation.
    Id. at 127. “[T]he resolution of conflict between the coordinate branches
    in these situations must be regarded as an opportunity for a constructive
    modus vivendi, which positively promotes the functioning of our system.”
    Id. at 130.
    In light of this history and precedent, both the Executive Branch and
    Congress have recognized their respective constitutional obligations to
    seek accommodation through good faith negotiations over their respective
    interests. See, e.g., Elizabeth B. Bazan & Morton Rosenberg, Cong.
    Research Serv., Congressional Oversight of Judges and Justices 10 (May
    31, 2005) (“Although the accommodation process between Congress and
    the Executive Branch is conducted in a highly political atmosphere, the
    arguments made by each side are usually grounded in legal doctrine and
    rely heavily on their interpretations and past experiences. At times, the
    Executive Branch is able to persuade Congress that a particular request is
    insufficiently weighty[.]”); Congressional Requests, 13 Op. O.L.C. at 159
    38
    Congressional Oversight of the White House
    (“The process of accommodation requires that each branch explain to the
    other why it believes its needs to be legitimate. Without such an explana-
    tion, it may be difficult or impossible to assess the needs of one branch
    and relate them to those of the other.”); Assertion of Executive Privilege
    in Response to a Congressional Subpoena, 
    5 Op. O.L.C. 27
    , 31 (1981)
    (Smith, Att’y Gen.) (“The accommodation required is not simply an
    exchange of concessions or a test of political strength. It is an obligation
    of each branch to make a principled effort to acknowledge, and if possible
    to meet, the legitimate needs of the other branch.”). The accommodation
    process has usually proved successful in reconciling congressional infor-
    mational needs with the Executive Branch’s interests, and so congression-
    al committees rarely pursue citing executive branch officials for contempt
    of Congress to enforce their document and testimonial subpoenas, see
    infra Part IV.A, and Presidents rarely invoke executive privilege.
    Because the accommodation process is premised upon working out
    each branch’s needs and interests, the outcome of that process may differ
    when it comes to the White House. As explained in Part I, the White
    House functions separately from the departments and agencies and histor-
    ically has been “a combined administrative, advisory, planning, and
    policy-formulating office serving the President in an intimate, indispensa-
    ble capacity.” Clinton L. Rossiter, The Constitutional Significance of the
    Executive Office of the President, 43 Am. Pol. Sci. Rev. 1206, 1215
    (1949). To a much greater degree than other parts of the Executive
    Branch, the White House serves to advise and assist the President, par-
    ticularly in the discharge of his constitutional functions. Although there
    may be occasions when a congressional committee can appropriately seek
    information from the White House, particularly where the President is
    charged with the discharge of statutory functions, the separation of pow-
    ers principles discussed above impose significant constraints on White
    House oversight, as reflected in long-standing practice. 15 The timing and
    15 See, e.g., Letter for John W. Byrnes, House of Representatives, from Joseph Camp-
    bell, Comptroller General of the United States at 2 (Sept. 18, 1962) (“[W]e are certain you
    understand that [Comptroller General] investigations of White House activities are not
    subject to the same techniques as those conducted in the various departments and agen-
    cies. Files of the White House Office, with the exception of financial records, are normal-
    ly not available to us. Also, White House personnel are not always available for inter-
    view. This has been the situation in all recent Administrations.”); see also Cong. Research
    39
    45 Op. O.L.C. __ (Jan. 8, 2021)
    scope of inquiries directed to the White House, and the accommodations
    offered by the White House, must be sensitive to the President’s interests
    in autonomy and confidentiality, as well as the heightened confidentiality
    interests in White House communications. They also must reflect the
    different balance of needs and interests that applies to oversight of the
    White House: Congressional needs are often more attenuated (because it
    is the departments and agencies that administer most statutory programs),
    and the Executive Branch’s institutional interests are greater (based on the
    President’s need for autonomy and the heightened confidentiality inter-
    ests).
    As with all oversight requests, the White House may properly insist
    that a congressional committee articulate a legitimate legislative purpose
    for inquiries directed at the White House. See Barenblatt, 
    360 U.S. at
    111–12; Watkins, 
    354 U.S. at 187
    . The committee’s legislative purpose
    should be “carefully assess[ed],” whether or not the information sought is
    likely to be protected by executive privilege. Mazars, 140 S. Ct. at 2035.
    The White House should independently “examine the objective fit be-
    tween that purpose and the information sought, as well as any other evi-
    dence that may bear upon the Committee’s true objective.” President’s
    Tax Returns, 43 Op. O.L.C. __, at *17. If the legitimate purpose underly-
    ing the oversight request appears unclear, White House staff may request
    that the committee clarify that purpose. See id. at *26 (“The separation of
    powers would be dramatically impaired were the Executive required to
    . . . accept[] the legitimacy of any reason proffered by Congress, even in
    the face of clear evidence to the contrary.”). The White House must take
    care to ensure that the requests involve a legitimate legislative purpose
    Serv., RL31351, Presidential Advisers’ Testimony Before Congressional Committees: An
    Overview 21 (Dec. 15, 2014) (“Given the tradition of comity between the executive and
    legislative branches, Congress often elects not to request the appearance of presidential
    aides. When Congress has requested the appearance of such aides, Presidents and their
    aides have at times resisted, asserting the separation of powers doctrine and/or executive
    privilege.” (footnote omitted)); Louis Fisher, White House Aides Testifying Before Con-

    and do not intrude upon the exclusive constitutional prerogatives of the
    President.
    In addition, because any congressional inquiry must respect the “auton-
    omy” of the President’s close advisers and “the confidentiality of [their]
    communications,” Cheney, 
    542 U.S. at 385
    , a congressional committee
    seeking information about a statutory program should generally be di-
    rected first to the agency that administers the program in question. See
    Mazars, 140 S. Ct. at 2035–36 (explaining that “[o]ccasion[s] for consti-
    tutional confrontation between the two branches should be avoided when-
    ever possible” and that “Congress may not rely on the President’s infor-
    mation if other sources could reasonably provide Congress the
    information it needs” (internal quotation marks omitted)). This practice of
    exhaustion is rooted in separation of powers principles and the practical
    realities of White House operations. It is crucial to the functioning of the
    Executive Branch that White House staff members be able to perform
    their functions independently and effectively in service of the President.
    Congressional efforts to conduct extensive and time-consuming oversight
    of the White House could seriously interfere with that mission. When
    information Congress seeks is available from an agency, there is no rea-
    son to subject the President’s advisers to potentially burdensome over-
    sight requests, especially because aspects of their work are far more likely
    to implicate the presidential communications component of executive
    privilege. 16
    Accordingly, when faced with a congressional request for information
    that reasonably could be acquired from a department or agency, White
    House staff often advise the relevant committee that it should pursue its
    request there. Only if the committee has exhausted the possibility of
    obtaining the necessary information elsewhere, and has determined that
    the necessary information may be obtained only from the White House,
    should the committee direct its inquiry to the White House.
    16 Courts have credited these concerns in a series of cases discussing FOIA requests.
    The D.C. Circuit, for instance, has declined to allow FOIA requests for the President’s
    White House visitor logs—even though the logs were held by the Secret Service, which is
    housed within the Department of Homeland Security, rather than the White House—
    because such requests “could render FOIA a potentially serious congressional intrusion
    into the conduct of the President’s daily operations.” Judicial Watch, Inc. v. U.S. Secret
    Serv., 726 F.3d at 226.
    41
    45 Op. O.L.C. __ (Jan. 8, 2021)
    When a committee’s request to the White House concerns statutory
    functions, is within the committee’s delegated oversight authority, and
    rests on a legitimate legislative purpose—and after the committee has
    attempted to seek such information from any relevant agencies—then the
    White House should consider how to accommodate the committee’s needs
    in a manner consistent with the interests of the Executive Branch. See
    AT&T, 
    567 F.2d at 127
    . An important feature of the accommodation
    process is the dialogue that takes place between the committee and the
    White House to ensure that information requests are not “unnecessarily
    broad.” Cheney, 
    542 U.S. at 390
    . Given the separation of powers princi-
    ples at stake, these negotiations can help “narrow the scope of possible
    conflict between the branches,” and ensure that a request is “no broader
    than reasonably necessary to support Congress’s legislative objective.”
    Mazars, 140 S. Ct. at 2036.
    The accommodation process has several rules of the road. First, the
    White House may properly demand that Congress’s request be reasonably
    specific. “The specificity of [a committee’s] request ‘serves as an im-
    portant safeguard against unnecessary intrusion into the operation of the
    Office of the President.’” Id. (quoting Cheney, 
    542 U.S. at 387
    ). A com-
    mittee should clearly explain the nature and scope of its request and
    provide the White House with an opportunity to seek further explanation
    if the White House believes that the request is vague or otherwise ambig-
    uous. Second, the “burdens imposed by a congressional [request] should
    be carefully scrutinized, for they stem from a rival political branch that
    has an ongoing relationship with the President and incentives to use
    subpoenas [or other requests] for institutional advantage.” 
    Id.
     Finally,
    given the relatively small staff and resources available in the White
    House, the committee must afford the White House sufficient time to
    respond to its inquiry and flexibility in its manner and mode of response.
    In light of these considerations, the White House typically seeks to ac-
    commodate congressional requests by providing written responses or oral
    briefings on relevant activities or policies, supplemented sometimes by
    the production of specific non-privileged documents. The White House
    does not ordinarily undertake the burden of reviewing and producing
    e-mails and other documents, which generally will consist primarily of
    deliberative communications within the White House or between the
    42
    Congressional Oversight of the White House
    White House and other parts of the Executive Branch. Searching through
    and processing the thousands of presumptively privileged e-mails likely to
    be responsive to a single request undoubtedly would divert the relatively
    small White House staff from its important work for the President. Fur-
    ther, the practice of providing written responses and oral briefings instead
    of e-mails and other internal communications helps preserve the Presi-
    dent’s ability to obtain full and frank advice from White House staff. This
    is critical to avoid chilling the candor of White House communications,
    since “[t]he President himself must make decisions relying substantially,
    if not entirely, on the information and analysis supplied by advisers.”
    Sealed Case, 121 F.3d at 750.
    Such responses and briefings, in lieu of documents, are generally suffi-
    cient to satisfy the legitimate information needs of congressional commit-
    tees. As noted above, because the purpose of oversight is to enable Con-
    gress to “exercise its legislative function advisedly and effectively,”
    McGrain, 
    273 U.S. at 161
    , rarely do the “legislative judgments” informed
    by the oversight process depend on a “precise reconstruction of past
    events,” Senate Select Comm., 
    498 F.2d at 732
    ; see Mazars, 140 S. Ct. at
    2036; Authority to Investigate for Impeachment, 44 Op. O.L.C. __, at *10.
    Moreover, “‘Congress will seldom have any legitimate legislative interest
    in knowing the precise predecisional positions and statements of particu-
    lar executive branch officials.’” Congressional Requests, 13 Op. O.L.C. at
    159 (citation omitted). Although in appropriate circumstances agencies
    may offer the accommodation of access to deliberative materials (permit-
    ting them to be read but not copied, for example), such an accommodation
    would be quite unusual for internal White House and intra-EOP delibera-
    tive communications because of the President’s unique need for autonomy
    and heightened confidentiality interests.
    IV. Congressional Subpoenas to the White House
    We next turn to consider the procedures by which congressional com-
    mittees may issue and seek to enforce subpoenas. Drawing on the consti-
    tutional principles discussed in the prior Parts, we outline some of the
    grounds on which the Executive Branch has commonly objected to the
    scope or enforceability of congressional subpoenas.
    43
    45 Op. O.L.C. __ (Jan. 8, 2021)
    A. Issuance and Enforcement of Subpoenas
    Congress’s subpoena power is inherent in its investigative authority.
    See Mazars, 140 S. Ct. at 2031; U.S. Servicemen’s Fund, 
    421 U.S. at 504
    (observing that the issuance of subpoenas “has long been held to be a
    legitimate use by Congress of its power to investigate”); Independent
    Counsel Act Requests, 10 Op. O.L.C. at 81–82 (discussing congressional
    authority to issue subpoenas). Because the authority to issue subpoenas is
    an inherent constitutional power, Congress does not need statutory author-
    ization to issue a subpoena, but any “exercise of subpoena power must be
    authorized by the relevant House.” Independent Counsel Act Requests, 10
    Op. O.L.C. at 82 (citing Reed v. Cty. Comm’rs, 
    277 U.S. 376
    , 389 (1928);
    McGrain, 
    273 U.S. at 158
    ); see also Authority to Investigate for Im-
    peachment, 44 Op. O.L.C. __, at *19 (“a committee’s authority to compel
    the production of documents and testimony depends entirely upon the
    jurisdiction provided by the terms of the House’s delegation”).
    The Senate rules provide committees with the authority to subpoena
    witnesses, “correspondence, books, papers, and documents,” Senate Rule
    XXVI(1), and similarly the rules of the House of Representatives author-
    ize committees to subpoena “witnesses and the production of such books,
    records, correspondence, memoranda, papers, and documents as [they]
    consider[] necessary,” House Rule XI.2(m)(1)(B). The precise procedures
    for issuing a subpoena vary depending on the rules of the chamber and
    committee involved. See Michael L. Koempel, Cong. Research Serv.,
    R44247, A Survey of House and Senate Committee Rules on Subpoenas 5–
    16 (Jan. 29, 2018) (“Survey of Committee Rules”) (detailing House and
    Senate chamber and committee rules on subpoena procedures). In the
    House, subpoenas generally may be issued by a committee “only when
    authorized by the committee . . . , a majority being present,” but commit-
    tees may delegate that power to “the chair of the committee under such
    rules and under such limitations as the committee may prescribe.” House
    Rule XI.2(m)(3)(A)(i); see also Survey of Committee Rules at 1 (“[m]ost
    House committees” have delegated subpoena power to their chairs). The
    Senate’s standing rules delegate to each committee responsibility for
    establishing subpoena procedures, and the procedures vary widely. See
    Senate Rule XXVI(2).
    44
    Congressional Oversight of the White House
    During Watergate and on several occasions more recently, congression-
    al committees have turned to the federal courts seeking the enforcement
    of subpoenas against executive branch officials. This is a marked depar-
    ture from long-standing practice: “Historically, disputes over congres-
    sional demands for presidential documents have not ended up in court.”
    Mazars, 140 S. Ct. at 2029; see Comm. on the Judiciary v. McGahn, 
    968 F.3d 755
    , 777 (D.C. Cir. 2020) (en banc) (noting that “there have been
    relatively few” such cases). The Supreme Court has recognized that
    “Congress and the Executive have nonetheless managed for over two
    centuries to resolve” privilege disputes without recourse to the Supreme
    Court. Mazars, 140 S. Ct. at 2031. And although Mazars arose in an
    unusual posture that made it justiciable—because the President in his
    personal capacity sought to require his accountants to comply with their
    confidentiality obligations—that case was the first such dispute to reach
    the Supreme Court. See id. (“we have never considered a dispute over a
    congressional subpoena for the President’s records”).
    In recent decades, the Department of Justice has maintained that a con-
    gressional suit to enforce a subpoena against the Executive Branch is not
    justiciable. 17 First, such a lawsuit typically alleges an abstract “type of
    institutional injury (the diminution of legislative power)” that does not
    constitute a “‘concrete and particularized’” legal injury as required for
    Article III standing—a doctrine that applies “especially rigorous[ly]” in
    separation of powers cases. Raines v. Byrd, 
    521 U.S. 811
    , 819–21 (1997)
    (quoting Lujan v. Defs. of Wildlife, 
    504 U.S. 555
    , 560 (1992)). Second, as
    noted above, such suits were nearly unprecedented as a historical matter,
    despite the history of oversight disputes between Congress and the Execu-
    17 Although a congressional committee may not seek judicial enforcement of a subpoe-
    na against the Executive Branch, there are some cases, such as Mazars, where a suit
    involving a congressional subpoena would be justiciable. The dispute there no doubt
    presented “significant separation of powers issues” and was in meaningful respects an
    inter-branch dispute, 140 S. Ct. at 2033–34, but as noted, it involved the President’s
    private right in his personal papers and the legal obligations owed to him by third parties
    that were the actual recipients of the subpoenas, see id. at 2027–28; see also Comm. on
    the Judiciary v. McGahn, 
    951 F.3d 510
    , 531 (D.C. Cir. 2020) (“we may adjudicate cases
    concerning congressional subpoenas if they implicate the rights of private parties”),
    vacated on reh’g en banc,

    ; United States v. Am. Tel. & Tel. Co., 
    551 F.2d 384
    , 390–91 (D.C. Cir. 1976) (holding that an executive branch suit to enjoin a third party
    from complying with a congressional subpoena was justiciable).

    ally thought to be capable of resolution through the judicial process.’” Id.

    554 U.S. 269
    , 274 (2008) (“history
    and tradition offer a meaningful guide to the types of cases that Article III
    empowers federal courts to consider”). It was not until 1974—almost two
    centuries after the Constitution’s ratification—that a committee of Con-
    gress appears to have first brought a civil action attempting to compel
    executive branch compliance with a subpoena. See Senate Select Comm.,
    
    498 F.2d 725
    . In that case, a statute purported to give the District Court
    for the District of Columbia jurisdiction in “any civil action” brought by
    the Senate committee investigating the Watergate scandal to “enforce and
    secure a declaration concerning the validity of any subpoena.” Pub. L. No.
    93-190, § (a), 
    87 Stat. 736
    , 736 (1973); see also Senate Select Comm., 
    498 F.2d at
    727–28 (explaining the jurisdiction conferred by the special law).
    The court of appeals did not address whether the case was justiciable as a
    constitutional matter. No committee of Congress brought a subpoena-
    enforcement action again until 2008, when House committees began filing
    such suits with some regularity. 18
    Earlier this year, a panel of the D.C. Circuit agreed with the Depart-
    ment and dismissed a congressional suit seeking enforcement of a sub-
    poena to the former Counsel to the President. Comm. on the Judiciary v.
    McGahn, 
    951 F.3d 510
     (D.C. Cir. 2020), vacated on reh’g en banc, 
    968 F.3d 755
    . The panel concluded that “separation-of-powers principles and
    historical practice” bar federal courts from exercising jurisdiction over
    committee suits “to enforce a congressional subpoena against the Execu-
    tive Branch.” Id. at 522. The court reheard the case en banc and vacated
    that ruling, holding that congressional committees could assert informa-
    tional injuries no less than private parties because the constitutional
    separation of powers erects no “structural barrier to judicial involvement
    in informational disputes between the elected branches.” McGahn, 968
    18 See Complaint for Declaratory and Injunctive Relief, Comm. on the Judiciary v.
    Miers, No. 08-0409 (D.D.C. Mar. 10, 2008); Complaint, Comm. on Oversight & Gov’t

    F.3d at 768. But see id. at 783–84 (Griffith, J., dissenting) (faulting the
    majority for “its neglect of the interbranch nature of this dispute”). On
    remand, however, the panel held that congressional committees nonethe-
    less lack a cause of action to seek judicial enforcement of a subpoena in
    this context. McGahn, 
    973 F.3d 121
     (D.C. Cir. 2020), reh’g en banc
    granted, No. 19-5331 (Oct. 15, 2020).
    As the panel recognized, even if congressional suits to enforce subpoe-
    nas to the Executive Branch were justiciable, they fall outside the statuto-
    ry jurisdiction of the federal courts and are unsupported by any cause of
    action. Although committees have relied upon the federal-question statute,
    
    28 U.S.C. § 1331
    , as a basis for subject-matter jurisdiction, a more specif-
    ic statute governs jurisdiction over congressional subpoena-enforcement
    suits, 
    id.
     § 1365(a). This latter statute provides jurisdiction only for Sen-
    ate actions, and more importantly excludes all actions to enforce subpoe-
    nas against executive branch officials who raise “a governmental privi-
    lege.” Id.; see McGahn, 951 F.3d at 522 (“The obvious effect of section
    1365(a)’s carve-out is to keep interbranch information disputes like this
    one out of court.”). Indeed, the carve-out sought to accommodate the
    Executive Branch’s view, expressed by then-Assistant Attorney General
    Scalia, that “the Supreme Court should not and would not undertake to
    adjudicate the validity of the assertion of executive privilege against the
    Congress.” Executive Privilege—Secrecy in Government: Hearings on S.
    2170, S. 2378, and S. 2420 Before the Subcomm. on Intergovernmental
    Relations of the S. Comm. on Gov’t Operations, 94th Cong. 83 (1975)
    (statement of Assistant Attorney General Scalia); see also id. at 84
    (“[T]he courts are precisely not the forum in which this issue should be
    resolved.”).
    Moreover, in addition to lacking a statutory basis for jurisdiction,
    House committees lack any cause of action to enforce their subpoenas.
    The statute that provides a cause of action to enforce Senate subpoenas,
    2 U.S.C. § 288d, like section 1365(a), applies only to the Senate (and
    imposes various restrictions). That limitation (among other considera-
    tions) also makes clear, as the McGahn panel explained, that neither an
    implied cause of action under Article I of the Constitution nor an equita-
    ble cause of action is available to the House in this context. See 973 F.3d
    at 123–24; see also id. at 124–25 (applying Supreme Court and circuit
    precedent to reject the argument that the Declaratory Judgment Act, 28
    47
    45 Op. O.L.C. __ (Jan. 8, 2021)
    U.S.C. § 2201, provides a cause of action). As the Supreme Court has
    recognized, Congress’s authority “to compel production of evidence
    differs widely from authority to invoke judicial power for that purpose.”
    Reed, 
    277 U.S. at 389
    .
    In the 1980s, this Office opined that these civil suits do lie within the
    constitutional and statutory jurisdiction of the federal courts and are
    appropriate for judicial resolution. See Independent Counsel Act Requests,
    10 Op. O.L.C. at 87–89; Prosecution for Contempt of Congress of an
    Executive Branch Official Who Has Asserted a Claim of Executive Privi-
    lege, 
    8 Op. O.L.C. 101
    , 137 (1984) (“Prosecution for Contempt of Con-
    gress”). 19 But those statements preceded significant decisions in which the
    Supreme Court clarified the requirements of Article III standing (most
    notably Raines v. Byrd ) and amendments to 
    28 U.S.C. § 1365
    (a) enacted
    in 1996 that confirm Congress’s intent to bar inter-branch informational
    disputes from federal court. See McGahn, 951 F.3d at 522 (discussing
    1996 legislative history). In fact, the author of one such OLC opinion,
    Assistant Attorney General Theodore Olson, argued while later serving as
    Solicitor General that these developments in the law undermined the
    Department’s earlier view. See Defendant’s Memorandum of Points &
    Auths. in Reply to Plaintiff ’s Opposition to Motion to Dismiss, Walker v.
    Cheney, 
    230 F. Supp. 2d 51
     (D.D.C. 2002) (No. 02-340), 
    2002 WL 32388026
     (relying on Raines to argue that a suit brought by the Comptrol-
    ler General against executive branch officials was nonjusticiable). This
    Office was consulted on that brief at the time, and we continue to think
    that these developments in the law support the Department’s current view
    that Congress may not properly seek to enforce its subpoenas in federal
    court against executive branch officials.
    Congress has increasingly turned to civil enforcement suits as an alter-
    native to traditional efforts to compel executive branch officials to pro-
    vide information that Congress has requested. Historically, Congress has
    had no shortage of ways to use its powers to press executive branch
    officials to negotiate and to comply with appropriate informational de-
    The Department of Justice even attempted to bring an analogous suit against the
    19
    House in 1983. See United States v. House of Representatives, 
    556 F. Supp. 150
     (D.D.C.
    1983) (dismissing, on prudential grounds, a suit seeking a declaratory judgment that the
    Administrator of the Environmental Protection Agency had lawfully withheld privileged
    documents from Congress).
    48

    mands. Congress has the power of the purse, see U.S. Const. art. I, § 9,
    cl. 7 (“No Money shall be drawn from the Treasury, but in Consequence
    of Appropriations made by Law”), as well as the power to impeach and
    remove executive officers, see id. § 2, cl. 5; id. § 3, cls. 6–7, and the
    Senate’s consent is necessary for the appointments of many senior execu-
    tive officers, see id. art. II, § 2, cl. 2. Congress also may press its case
    directly to the press and to the public at large. Those powers have fre-
    quently been deployed as a means of ensuring that the Executive Branch
    acts in accord with the “tradition of negotiation and compromise,”
    Mazars, 140 S. Ct. at 2031, that has led to the successful resolution of
    many oversight disputes.
    Congress also has other, more direct means of ensuring compliance
    with subpoenas. One theoretical option would be for the House or Senate
    to invoke its inherent contempt powers and instruct the Sergeant-at-Arms
    to arrest an individual cited for contempt. See Jurney v. MacCracken, 
    294 U.S. 125
     (1935); Anderson v. Dunn, 19 U.S. (6 Wheat.) 204 (1821). How-
    ever, Congress has not sought to arrest any person for contempt in more
    than 80 years, see Independent Counsel Act Requests, 10 Op. O.L.C. at
    86, and has not sought to arrest an executive branch official in more than
    a century, see McGahn, 968 F.3d at 776. Any effort by Congress to arrest
    a White House official for noncompliance with a subpoena based upon a
    legitimate separation of powers objection would, besides raising serious
    practical concerns, likely be unconstitutional. See Immunity of the Former
    Counsel, 43 Op. O.L.C. __, at *20–21 (“The constitutional separation of
    powers bars Congress from exercising its inherent contempt power in the
    face of a presidential assertion of executive privilege. An attempt to
    exercise inherent contempt powers in such a circumstance would be
    without precedent and would immeasurably burden the President’s ability
    to assert the privilege and to carry out his constitutional functions.” (in-
    ternal quotation marks omitted)). Congressional authority to arrest execu-
    tive officials for actions properly taken to protect the prerogatives of the
    Executive Branch is the type of “great substantive and independent pow-
    er[]” that the Constitution would not have left to mere implication. Nat’l

    2 U.S.C. § 192
    . Under the statute, where a
    person who is summoned to give testimony or to produce papers and
    “willfully makes default, or who, having appeared, refuses to answer any
    question pertinent to the question under inquiry,” 
    id.,
     the President of the
    Senate or the Speaker of the House may refer to an “appropriate United
    States attorney” for prosecution an individual who refuses to comply with
    a subpoena. 
    Id.
     § 194. Congress has invoked the criminal contempt statute
    against private parties and executive branch officials as well.
    We have long maintained, however, that the contempt statute does not
    apply to executive branch officials who resist congressional subpoenas in
    order to protect the prerogatives of the Executive Branch. See Prosecution
    for Contempt of Congress, 8 Op. O.L.C. at 129–42. Moreover, given that
    the prosecution authority is part of the executive power, Congress may
    only refer an individual to a United States Attorney for a contempt prose-
    cution; the Department of Justice ultimately has the prosecutorial discre-
    tion to decide whether a person should be indicted and prosecuted. See
    Nixon, 
    418 U.S. at 693
     (“the Executive Branch has exclusive authority
    and absolute discretion to decide whether to prosecute a case”); Prosecu-
    tion for Contempt of Congress, 8 Op. O.L.C. at 119–20 (Department of
    Justice controls whether any contempt prosecution will be brought). In
    response to criminal referrals for two White House officials in 2008, for
    instance, Attorney General Michael Mukasey notified the Speaker of the
    House that the Department of Justice would “not bring the congressional
    contempt citations before a grand jury or take any other action to prose-
    cute,” because, in light of the President’s assertions of executive privi-
    lege, the “non-compliance by [the President’s Chief of Staff ] and [the
    former Counsel to the President] . . . did not constitute a crime.” Letter
    for Nancy Pelosi, Speaker of the House, from Michael B. Mukasey,
    Attorney General at 2 (Feb. 29, 2008); see also Prosecution for Contempt
    of Congress, 8 Op. O.L.C. at 128 (contempt statute does not override the

    Congressional committees have generally sought enforcement of sub-
    poenas against noncompliant witnesses only with an authorization from
    the full House or Senate. See 2 U.S.C. § 288b(b) (requiring “adoption of a
    resolution by the Senate” to authorize a Senate subpoena-enforcement
    50
    Congressional Oversight of the White House
    suit); House Rule XI.2(m)(3)(C) (“Compliance with a subpoena issued by
    a [House] committee or subcommittee . . . may be enforced only as au-
    thorized or directed by the House.”); Cong. Research Serv., RL30548,
    Hearings in the U.S. Senate: A Guide for Preparation and Procedure 11
    (Mar. 18, 2010) (“Compliance with a [Senate committee] subpoena can be
    enforced only at the direction of the Senate.”); Independent Counsel Act
    Requests, 10 Op. O.L.C. at 82–83 (discussing procedures for enforcing
    House subpoenas). 20 If the committee seeks to enforce the subpoena by
    holding the recipient in contempt, the committee (by a majority vote)
    must seek such approval by “report[ing] a resolution of contempt to the
    floor.” Louis Fisher, Cong. Research Serv., Congressional Investigations:
    Subpoenas and Contempt Power 7 (Apr. 2, 2003) (“Subpoenas and Con-
    tempt Power”); see also 
    2 U.S.C. § 194
     (requiring, for a contempt of
    Congress prosecution, that noncompliance with a subpoena be reported to
    the House or Senate, or House or Senate leadership if Congress is not in
    session). The full House or Senate must then “vote in support of the
    contempt citation” before the contempt may be referred to the U.S. Attor-
    ney. Subpoenas and Contempt Power at 7; see also Wilson v. United
    States,

    , 203 (D.C. Cir. 1966) (explaining that a chamber-
    wide vote provides “a ‘check’ on hasty action by a committee” and avoids
    a situation where “the allegedly insulted committee . . . provide[s] the sole
    legislative determination whether to initiate proceedings to prosecute for
    contempt”).
    Committees of Congress have issued and likely will continue to issue
    subpoenas for documents and testimony to White House personnel. Less
    certain, however, is whether congressional entities have any authority to
    seek to compel compliance with such subpoenas in court. We believe that
    congressional suits to enforce subpoenas to executive branch officials fall
    outside the constitutional and statutory jurisdiction of the federal courts;
    20 Where recourse has been made to the courts, the House or Senate has typically au-
    thorized such an action by resolution. Todd Garvey, Cong. Research Serv., R45653,
    Congressional Subpoenas: Enforcing Executive Branch Compliance 5 (Mar. 27, 2019);
    see, e.g., H.R. Res. 706, 112th Cong. (2012) (authorizing suit to enforce subpoena to
    Attorney General Holder). In the 116th Congress, however, the House broke from this
    practice by adopting a resolution enabling committees to file suit whenever authorized by
    the Bipartisan Legal Advisory Group, H.R. Res. 430 (2019), which comprises the House
    Speaker and majority and minority leaderships, House Rule II.8(b).

    45 Op. O.L.C. __ (Jan. 8, 2021)
    the inherent contempt mechanism appears to have fallen into desuetude,
    and would present grave constitutional concerns if deployed against
    executive branch officials acting to protect the lawful prerogatives of the
    Executive; and the Executive Branch has discretion to refuse to bring a
    contempt of Congress criminal prosecution against one of its officials in
    such circumstances.
    B. Validity of Subpoenas Issued to the White House
    It is the Executive Branch’s settled policy to work to accommodate
    congressional requests for information in a manner consistent with the
    Executive’s constitutional and statutory obligations. Historically, how-
    ever, congressional subpoenas to executive branch officials have raised
    a variety of separation of powers concerns. This section identifies and
    discusses a number of legal defects, several of which are discussed at
    greater length above, that have commonly arisen in subpoenas involv-
    ing the White House. These limitations on Congress’s oversight powers
    are rooted in the separation of powers, and observing them serves to
    prevent Congress from “aggrandiz[ing] itself at the [Executive’s] ex-
    pense.” Mazars, 140 S. Ct. at 2034.
    Lack of Oversight Authority or Legitimate Legislative Purpose. As we
    have discussed, all congressional oversight inquiries must be conducted in
    support of Congress’s legislative authority under Article I of the Constitu-
    tion. See id. at 2031–32, 2035–36; McGrain, 
    273 U.S. at 177
    . A subpoena
    that seeks material or testimony on matters beyond Congress’s legislative
    authority, such as the exercise of a constitutional power vested exclusive-
    ly in the Executive Branch, is beyond Congress’s oversight authority. See
    Barenblatt, 
    360 U.S. at
    111–12.
    Infringement of Presidential Autonomy and Confidentiality. Congres-
    sional inquiries to the White House are constrained by “the Executive
    Branch’s interests in maintaining the autonomy of its office and safe-
    guarding the confidentiality of its communications.” Cheney, 
    542 U.S. at 385
    . In certain circumstances, compliance with a congressional subpoena
    directed at the White House may unduly impair the Executive’s “ability to
    discharge its constitutional responsibilities.” 
    Id. at 382
    . For example,
    compliance with a subpoena that is excessively broad or intrusive might
    burden White House personnel to a degree that prevents them from effec-
    52
    Congressional Oversight of the White House
    tively advising and assisting the President in the performance of his
    constitutional duties. In that circumstance, it would be unconstitutional to
    enforce such an unduly broad subpoena. Of course, the accommodation
    process serves to ensure that congressional requests are tailored or nar-
    rowed so as to avoid infringement of presidential autonomy and confiden-
    tiality while satisfying Congress’s legitimate needs for relevant infor-
    mation.
    Immunity of White House Officials from Compelled Testimony. Re-
    latedly, the White House has consistently resisted subpoenas that seek to
    compel the President’s immediate advisers to testify before congressional
    committees. The White House has declined to make many of the Presi-
    dent’s immediate advisers available since the establishment of the EOP,
    and for almost 50 years, the Department of Justice has articulated this
    position as a legal immunity—that “the President and his immediate
    advisers are absolutely immune from testimonial compulsion by a Con-
    gressional committee on matters related to their official duties.” Immunity
    of the Former Counsel, 43 Op. O.L.C. __, at *3 (internal quotation marks
    omitted). 21 As Assistant Attorney General Rehnquist explained:
    The President and his immediate advisers—that is, those who cus-
    tomarily meet with the President on a regular or frequent basis—
    should be deemed absolutely immune from testimonial compulsion
    by a congressional committee. They not only may not be examined
    with respect to their official duties, but they may not even be com-
    pelled to appear before a congressional committee.
    Memorandum for John D. Ehrlichman, Assistant to the President for
    Domestic Affairs, from William H. Rehnquist, Assistant Attorney Gen-
    eral, Office of Legal Counsel, Re: Power of Congressional Committee to
    Compel Appearance or Testimony of “White House Staff ” at 7 (Feb. 5,
    1971); see also Immunity of the Former Counsel, 43 Op. O.L.C. __, at *7–
    21 Although this Office has spoken of this protection from compelled congressional
    testimony in terms of “immunity,” it may equally be viewed as a limitation on the breadth
    of Congress’s implied power to compel testimony. Cf. New York v. United States, 
    505 U.S. 144
    , 159 (1992) (“it makes no difference whether one views” a federalism question
    as turning upon “the limits of the power delegated to the Federal Government under the
    affirmative provisions of the Constitution” or the scope of the “sovereignty retained by
    the States under the Tenth Amendment”).

    45 Op. O.L.C. __ (Jan. 8, 2021)
    11 (listing historical examples of immediate presidential advisers refusing
    to testify); Letter for Phillip E. Areeda, Counsel to the President, from
    Antonin Scalia, Assistant Attorney General, Office of Legal Counsel, att.
    at 6 (Sept. 25, 1974) (“at least since the Truman Administration,” presi-
    dential advisers “have appeared before congressional committees only
    where the inquiry related to their own private affairs or where they had
    received Presidential permission”).
    Consequently, in addition to invoking executive privilege over particu-
    lar questions, the President “can also direct them not even to appear
    before the committee.” Memorandum for Margaret McKenna, Deputy
    Counsel to the President, from John M. Harmon, Assistant Attorney
    General, Office of Legal Counsel, Re: Dual-Purpose Presidential Advis-
    ers app. at 7 (Aug. 11, 1977). For example, in 1981, Martin Anderson,
    President Reagan’s assistant for policy development, refused to appear
    before a House appropriations subcommittee responsible for funding his
    office. White House Counsel Fred F. Fielding explained that “[f ]rom the
    Administration of George Washington to the present day, it has been a
    central tenet of the doctrine of separation of powers among the three
    branches of the Federal Government that the President is not subject to
    questioning as to the manner in which he formulates Executive policy”;
    this principle “founded in practicality as well as tradition and law” “has
    also been applied to senior members of the President’s personal staff, who
    participate in the deliberative process through which such policies are
    developed.” Letter for Edward R. Roybal, Chairman, Subcommittee on
    Treasury, Postal Service, General Government, U.S. House of Representa-
    tives, from Fred F. Fielding, Counsel to the President (July 8, 1981),
    reprinted in H.R. Rep. No. 97-171, at 61 (1981). This testimonial im-
    munity safeguards the constitutional separation of powers by protecting
    the independence and autonomy of the Presidency from congressional
    interference; it also “protects the Executive Branch’s strong interests in
    confidentiality as well as the President’s ability to obtain sound and
    candid advice.” Immunity of the Former Counsel, 43 Op. O.L.C. __, at *5;
    accord Immunity of the Director of the Office of Political Strategy and
    Outreach from Congressional Subpoena, 
    38 Op. O.L.C. 5
    , 7–9 (2014).
    Immediate advisers to the President remain immune from compelled
    testimony about their official duties in that capacity even after they leave
    the White House. See Immunity of the Former Counsel, 43 Op. O.L.C. __,
    54
    Congressional Oversight of the White House
    at *15–16 (explaining that “the risk to the separation of powers and to the
    President’s autonomy posed by a former adviser’s testimony on official
    matters continues after the conclusion of that adviser’s tenure”). In deter-
    mining whether a person qualifies for this immunity, we have considered
    the day-to-day responsibilities of the adviser and the extent of his or her
    regular interaction with the President. Although most members of the
    White House staff do not qualify for immunity from compelled testimony,
    as a matter of policy the White House has generally opposed making any
    members of the White House staff available to testify, subject to the
    accommodation process.
    The Executive Branch’s position on immunity is well established by
    our precedent and practice, but the federal courts have looked less favora-
    bly on this position in the two cases in which the House sought to test it in
    court. The district courts to consider the question have held that senior
    presidential advisers do not, at least as a categorical matter, enjoy abso-
    lute immunity from compelled congressional testimony. See Comm. on
    the Judiciary v. Miers, 
    558 F. Supp. 2d 53
    , 105–06 (D.D.C. 2008); Comm.
    on the Judiciary v. McGahn, 
    415 F. Supp. 3d 148
    , 200–14 (D.D.C. 2019).
    But the first of those decisions was stayed pending appeal, Comm. on the
    Judiciary v. Miers, 
    542 F.3d 909
     (D.C. Cir. 2008) (per curiam), and then
    settled without enforcement of the subpoena, 
    2009 WL 3568649
     (D.C.
    Cir. Oct. 14, 2009). The second decision remains under review in the D.C.
    Circuit. In the latter case, two judges sitting on the D.C. Circuit panel
    similarly expressed doubt about the existence of this absolute immunity.
    See McGahn, 951 F.3d at 538–42 (Henderson, J., concurring); id. at 558
    (Rogers, J., dissenting). No precedential ruling has addressed the Execu-
    tive Branch’s position, however, which for decades has governed the
    Executive Branch’s negotiations with congressional committees seeking
    the testimony of the President’s immediate advisers.
    Exclusion of Counsel from Depositions. Although historically Con-
    gress has sought to obtain testimony from executive branch officials by
    means of voluntary interviews and public hearings, committees in recent
    years have made increasing use of depositions. See, e.g., H.R. Res. 6,
    116th Cong. § 103(a)(1) (2019) (authorizing committee chairs to “order
    the taking of depositions, including pursuant to subpoena, by a member or
    counsel of such committee”). And certain committees, based on the cur-
    rent House rules governing depositions, have attempted to bar executive
    55
    45 Op. O.L.C. __ (Jan. 8, 2021)
    branch witnesses from being accompanied by agency counsel at their
    depositions, allowing only private counsel. 165 Cong. Rec. H1216 (daily
    ed. Jan. 25, 2019) (“counsel for government agencies . . . may not at-
    tend”); see also, e.g., H. Comm. on Oversight & Reform Rule 15(e),
    116th Cong. (2019) (counsel “for agencies under investigation . . . may
    not attend”). The Executive Branch has repeatedly resisted this practice
    and sought to maintain the “[l]ongstanding Executive Branch policy and
    practice” of agency counsel accompanying agency officials when they are
    questioned by Congress. Letter for Henry Waxman, Chairman, Committee
    on Oversight and Government Reform, U.S. House of Representatives,
    from Dinah Bear, General Counsel, Council on Environmental Quality at
    2 (Mar. 12, 2007).
    This Office has advised that barring agency counsel from congressional
    depositions is unconstitutional because it “compromise[s] the President’s
    constitutional authority to control the disclosure of privileged information
    and to supervise the Executive Branch’s communications with congres-
    sional entities.” Exclusion of Agency Counsel, 43 Op. O.L.C. __, at *2;
    see also Authority of the Department of Health and Human Services to
    Pay for Private Counsel to Represent an Employee Before Congressional
    Committees, 41 Op. O.L.C. __, at *5 n.6 (Jan. 18, 2017) (noting that
    excluding agency counsel may raise “constitutional concerns” but reserv-
    ing the question). This principle of course applies to depositions of White
    House officials. In Exclusion of Agency Counsel, for example, we advised
    that a subpoena issued by the House Committee on Oversight and Reform
    to the former head of the White House Personnel Security Office was
    invalid on this basis. See 43 Op. O.L.C. __, at *2, *6. Subpoenas requiring
    White House personnel to testify without agency counsel are therefore
    without legal effect and may not constitutionally be enforced, civilly or
    criminally, against their recipients. See id. at *13–14.
    Failure to Exhaust the Accommodation Process. The White House
    often has responded to congressional requests by insisting that committees
    engage in the accommodation process. See supra Part III.C. A congres-
    sional committee may not avoid its obligation to participate in this consti-
    tutionally mandated process by issuing or seeking to enforce a subpoena
    before the accommodation process has run its course. Thus, White House
    officials have often cited a committee’s failure to exhaust the accommo-
    dation process in objecting to a congressional subpoena.
    56
    Congressional Oversight of the White House
    The accommodation process encompasses the exhaustion principle that
    we have discussed above. The White House may object to a committee’s
    refusal to seek necessary information from the relevant executive branch
    departments and agencies before directing requests to the White House.
    See Mazars, 140 S. Ct. at 2035–36 (“Congress may not rely on the Presi-
    dent’s information if other sources could reasonably provide Congress the
    information it needs in light of its particular legislative objective.”).
    Where a committee declines to honor its obligation to accommodate the
    legitimate needs of the White House, the committee may not lawfully
    begin the contempt process based upon good faith objections raised by
    White House officials.
    Assertion of Executive Privilege. An assertion of executive privilege
    authorized by the President is a well-established ground for resisting a
    congressional subpoena. See id. at 2032 (“recipients [of legislative sub-
    poenas] have long been understood to retain common law and constitu-
    tional privileges with respect to certain materials, such as . . . governmen-
    tal communications protected by executive privilege”). Executive
    privilege consists of several components, which vary in scope and the
    extent of protection from disclosure. See supra Part III.B. As relevant to
    the White House, a congressional committee may overcome an assertion
    of executive privilege based on the presidential communications compo-
    nent of the privilege only by “demonstrat[ing] that the information sought
    is ‘demonstrably critical to the responsible fulfillment of the Committee’s
    functions.’” Assertion of Executive Privilege for Documents Concerning
    Conduct of Foreign Affairs with Respect to Haiti, 
    20 Op. O.L.C. 5
    , 6
    (1996) (Reno, Att’y Gen.) (quoting Senate Select Comm., 
    498 F.2d at 731
    ). White House officials have an obligation to minimize the disclosure
    of privileged information and to protect the President’s authority to de-
    termine when it would be in the public interest to provide such infor-
    mation as an accommodation.
    This is not to say that the Executive Branch must or should claim exec-
    utive privilege as a prerequisite to asserting any confidentiality interests
    in connection with congressional oversight. A formal assertion of execu-
    tive privilege is a last resort in the sense that it is typically only needed
    when the Executive Branch has already asserted its confidentiality inter-
    ests, but the accommodation process has failed to produce a resolution
    and the relevant committee moves to initiate enforcement action by voting
    57
    45 Op. O.L.C. __ (Jan. 8, 2021)
    to recommend that the recipient of the subpoena be cited for contempt of
    Congress. 22 However, a formal assertion of privilege does not preclude
    the possibility of further negotiation and accommodation.
    Unreasonable Burden to Comply. White House officials also may de-
    cline to comply fully with the terms of a subpoena based on a concern that
    compliance would be unreasonably burdensome or impossible. Compared
    to the departments and agencies, White House components have small
    staffs who are primarily devoted to advising and assisting the President.
    Exempt from FOIA, these White House components do not have trained
    standing units devoted to document review and response work. Instead,
    these White House components need to divert staff from their work for
    the President to process congressional oversight requests. The White
    House is thus less likely than other parts of the Executive Branch to have
    the resources available to comply fully with subpoenas that are broad in
    scope and have urgent return dates.
    The federal courts’ rules of procedure for both civil and criminal cases
    relieve parties of the obligation to comply with a subpoena where the
    scope of the request and the return date make compliance unreasonably
    burdensome or impossible. See Fed. R. Civ. P. 45(d)(3)(A) (court “must
    quash or modify a subpoena that . . . fails to allow a reasonable time to
    comply”); Fed. R. Crim. P. 17(c)(2) (“court may quash or modify the
    subpoena if compliance would be unreasonable or oppressive”). Further, a
    party may not be held in contempt for noncompliance with a subpoena
    when compliance is an impossibility. See, e.g., In re Marc Rich & Co.,
    
    736 F.2d 864
    , 866 (2d Cir. 1984) (noting that the district court “made it
    perfectly clear that [a contemnor] simply had to produce appropriate
    affidavits attesting to the impossibility of compliance and the [contempt]
    judgment would be lifted”). Similar principles apply in the context of
    22 When this course of events moves too quickly to allow for an adequate executive
    privilege review, the President may make a “protective” assertion of executive privilege
    over a class of documents in order “to ensure [his] ability to make a final decision, after
    consultation with the Attorney General, as to which specific documents are deserving of a
    conclusive claim of executive privilege.” Protective Assertion of Executive Privilege

    It has long been the Executive Branch’s policy to “comply with Con-
    gressional requests for information to the fullest extent consistent with the
    constitutional and statutory obligations of the Executive Branch.” Reagan
    Memorandum at 1. But the critical functions that White House staff mem-
    bers play when advising and assisting the President in the performance of
    his constitutional duties require that congressional oversight of the White
    House be conducted differently from oversight of the departments and
    agencies. The necessary approach has been described at length in this
    memorandum opinion, but the core principle is that congressional com-
    mittees and the White House must work together to accommodate con-
    gressional needs for information about the Executive Branch’s discharge
    of statutory obligations in a manner that does not undermine the White
    House staff ’s ability to advise and assist the President.
