    On Appeal from the United States District Court
    for the Southern District of New York
    ARGUED: MARCH 22, 2022
    DECIDED: APRIL 20, 2022
    Before: CABRANES, RAGGI, Circuit Judges, and KORMAN, District Judge. 1
    The initial appeals of Defendants-Appellants Carl David
    Stillwell, Adam Samia, and Joseph Manuel Hunter (together,
    “Defendants”) were interrupted in October 2019, when we became
    aware that the Narcotic and Dangerous Drug Section (“NDDS”) of the
    U.S. Department of Justice had advised this Court that the District
    Court for the Southern District of New York (Ronnie Abrams, Judge)
    had entered a sealed protective order upon the filing of a post-trial, ex
    parte motion by the NDDS, which barred prosecutors in the U.S.
    Attorney’s Office for the Southern District of New York (“SDNY”) and
    defense counsel from reviewing certain classified documents.
    We vacated the District Court’s protective order and ordered
    those documents disclosed to both parties, leading defense counsel to
    argue for the first time on appeal that the prosecution had withheld
    the information in violation of Brady v. Maryland, 
    373 U.S. 83
     (1963). In
    an opinion of January 27, 2021, we remanded the case to the District
    Court with a limited mandate to determine, in the first instance,
    1  Judge Edward R. Korman, of the United States District Court for the
    Eastern District of New York, sitting by designation.

    suppressed, or both.” United States v. Stillwell, 
    986 F.3d 196
    , 201 (2d Cir.
    2021) (“Stillwell”).
    On remand, Defendants filed motions for a new trial under Rule
    33 of the Federal Rules of Criminal Procedure, which the District Court
    denied in a December 14, 2021 order, and a redacted version of that
    order was entered December 28, 2021.
    With jurisdiction now restored to us, we turn back to
    Defendants’ initial appeals from their judgments of conviction, and
    address those claims by summary order, entered the same day that this
    opinion is filed. We write separately here to address claims raised by
    Defendants Hunter and Stillwell in appealing the District Court’s Rule
    33 Order. In the unusual circumstances presented by this case, we are
    skeptical of the Government’s argument that the information withheld
    by the NDDS was not “suppressed” within the meaning of Brady.
    Nevertheless, we find that question unnecessary to resolve because we
    conclude that Defendants were not prejudiced by the withheld
    information, and it was therefore not material. Accordingly, we
    AFFIRM the December 14, 2021 order of the District Court denying
    Defendants’ motions under Rule 33.

    JOSÉ A. CABRANES, Circuit Judge:
    The initial appeals of Defendants-Appellants Carl David
    Stillwell, Adam Samia, and Joseph Manuel Hunter (together,
    “Defendants”) were interrupted in October 2019, when we became
    aware that the Narcotic and Dangerous Drug Section (“NDDS”) of the

    Attorney’s Office for the Southern District of New York (“SDNY”) and

    We vacated the District Court’s protective order and ordered
    those documents disclosed to both parties, leading defense counsel to

    post-trial motions pursuant to Federal Rules of Criminal Procedure 29 and 33,
    Stillwell filed a post-trial motion pursuant to Rule 29, and Samia joined those
    motions, all unrelated to Brady, which were all denied by the District Court. See

    2018 WL 4961453

    (“Post-Trial Opinion”). For clarity, we refer to the District Court’s October 15, 2018
    opinion and order denying those motions as its “Post-Trial Opinion,” and we refer
    to the District Court’s December 14, 2021 order denying the Rule 33 motions based
    on Brady claims made following our remand in Stillwell as its “Rule 33 Order.”

    With jurisdiction now restored to us, we turn back to
    Defendants’ initial appeals from their judgments of conviction, and
    address those claims by summary order, entered the same day that this
    opinion is filed. We write separately here to address claims raised by
    Defendants Hunter and Stillwell in appealing the District Court’s Rule
    33 Order. In the unusual circumstances presented by this case, we are
    skeptical of the Government’s argument that the information withheld
    by the NDDS was not “suppressed” within the meaning of Brady.
    Nevertheless, we find that question unnecessary to resolve because we
    conclude that Defendants were not prejudiced by the withheld
    information, and it was therefore not material. Accordingly, we
    AFFIRM the December 14, 2021 order of the District Court denying
    Defendants’ motions under Rule 33.
    I.    BACKGROUND
    A. Murder-for-Hire and Trial
    Paul Calder LeRoux (“LeRoux”) ran a transnational criminal
    organization engaged in money laundering, drug and weapons
    trafficking, and various acts of violence, including murder. The scale
    and variety of his outrageous criminal conduct defies an easy
    summary, and includes arms and technology dealings with Iran and
    North Korea, attempts at minor warlordism in Africa, and the plotting
    of a coup d’état in the Seychelles. As the District Court has aptly
    6
    characterized it, he committed “an array of crimes worthy of a James
    Bond villain.” 4
    In September 2012, the U.S. Drug Enforcement Administration
    (“DEA”) arrested LeRoux in Liberia and he began cooperating with
    authorities. The DEA used LeRoux’s cooperation to target various
    other members of his criminal organization.
    Defendants are among the members of that organization
    arrested by the DEA and jointly tried on five counts: (1) conspiracy to
    commit murder-for-hire, in violation of 
    18 U.S.C. § 1958
    (a); 5 (2)
    murder-for-hire, in violation of 
    18 U.S.C. § 1958
    (a); (3) conspiracy to
    murder and kidnap in a foreign country, in violation of 
    18 U.S.C. § 956
    (a); 6 (4) causing death with a firearm during and in relation to a
    4   Rule 33 Order, No. 13-cr-521-RA, ECF 796, at 22.
    5“Whoever travels in . . . interstate or foreign commerce, or uses . . . the mail
    or any facility of interstate or foreign commerce, with intent that a murder be
    committed in violation of the laws of any State or the United States as consideration
    for the receipt of, or as consideration for a promise or agreement to pay, anything
    of pecuniary value, or who conspires to do so . . . and if death results, shall be
    punished by death or life imprisonment, or shall be fined not more than $250,000,
    or both.” 
    18 U.S.C. § 1958
    (a).
    6 “Whoever, within the jurisdiction of the United States, conspires with one
    or more other persons . . . to commit at any place outside the United States an act
    that would constitute the offense of murder [or] kidnapping . . . if committed in the
    special maritime and territorial jurisdiction of the United States shall, if any of the
    conspirators commits an act within the jurisdiction of the United States to effect any
    object of the conspiracy, be punished [by] . . . imprisonment for any term of years
    or for life.” 
    18 U.S.C. § 956
    (a).
    7
    crime of violence, in violation of 
    18 U.S.C. § 924
    (j); 7 and (5) conspiracy
    to launder money, in violation of 
    18 U.S.C. § 1956
    (h). 8
    In particular, the Government alleged that in late 2011 and early
    2012, Hunter, Samia, and Stillwell conspired to commit murders-for-
    hire, for which purpose they traveled from the U.S. to the Philippines;
    that while there, Hunter provided Samia and Stillwell with “target
    packages” of individuals to kill; and that on February 12, 2012, Samia
    and Stillwell shot and killed Catherine Lee, a Filipino real estate
    agent. 9
    At trial, only Samia (who does not now appeal the District
    Court’s Rule 33 Order) maintained his actual innocence. Hunter and
    Stillwell both admitted involvement in Lee’s murder, but argued that
    the Government had failed to establish the jurisdictional element of
    7   “A person who, in the course of a violation of [
    18 U.S.C. § 924
    (c)] causes
    the death of a person through the use of a firearm, shall if the killing is a murder
    . . . be punished by death or by imprisonment for any term of years or for life.” 
    18 U.S.C. § 924
    (j).
    
    18 U.S.C. § 924
    (c) provides that “any person who, during and in relation to
    any crime of violence . . . uses or carries a firearm, or who, in furtherance of any
    such crime, possesses a firearm, shall, in addition to the punishment provided for
    such crime of violence[,] . . . if the firearm is discharged, be sentenced to a term of
    imprisonment of not less than 10 years.” 
    18 U.S.C. § 924
    (c).
    8 “Any person who conspires to commit [a money laundering offense] shall
    be subject to the same penalties as those prescribed for the offense the commission
    of which was the object of the conspiracy.” 
    18 U.S.C. § 1956
    (h); see 
    18 U.S.C. §§ 1956
    (a), 1957(a) (defining relevant money laundering offenses).

    8
    the 
    18 U.S.C. § 956
    (a) count, by not demonstrating that they had
    engaged in the conspiracy while in the U.S. 10
    The Government’s case advanced various items of evidence to
    establish the jurisdictional element of that count. In particular, as
    relevant to the arguments made by Hunter and Stillwell in appealing
    the Rule 33 Order, the Government submitted evidence that Hunter
    had flown to the U.S. on Korean Airlines Flight 35 on December 10,
    2011, and that he had met with Stillwell and Samia in North Carolina
    later that month. Further, LeRoux testified that a previous statement
    he had made to authorities in 2015 as part of a proffer—that Stillwell
    did not know about the murderous purpose of his trip to the
    Philippines until after leaving the U.S. (the “2015 Statement”)—had
    been a lie.
    Following a jury trial in April 2018, the three Defendants were
    convicted on all counts and sentenced principally to life in prison. 11
    Defendants timely filed their initial appeals.
    10  The parties agreed that Counts 1, 2, and 4 of the indictment were
    predicated on Count 3, the 
    18 U.S.C. § 956
    (a) count. Post-Trial Opinion, 
    2018 WL 4961453
    , at *2 n.4. As is relevant to Defendants’ appeal, the District Court instructed
    that in order to sustain a conviction on that count, the Government had to prove
    that a defendant “conspired with one or more members of the conspiracy while that
    defendant was physically present in the United States.” Joint App’x 974 (Trial Tr.
    2011:10–13).
    11 Hunter was not charged with Count 5. Judgments entered on October 12,
    2018 (Stillwell), November 14, 2018 (Samia), and March 25, 2019 (Hunter).
    9
    B. Appeal and Remand
    We heard oral argument on the initial appeals of Samia and
    Stillwell on October 30, 2019. 12
    As we described in Stillwell, soon after this, we became aware
    that in October 2018, the NDDS had filed a notice with this Court
    advising us that the District Court had entered a sealed protective
    order in the case barring prosecutors from the U.S. Attorney’s Office
    for the SDNY and defense counsel from reviewing certain classified
    documents. That protective order had been granted pursuant to
    Section 4 of the Classified Information Procedures Act (“CIPA”), 18
    U.S.C. app. 3 §§ 1 et seq., and Federal Rule of Criminal Procedure
    16(d), 13 upon the filing of a post-trial ex parte motion by an NDDS
    attorney, with no notice to counsel of record for any of the parties.
    12  Hunter’s notice of appeal was filed later, and his case was therefore not
    consolidated with Samia and Stillwell’s until April 30, 2020. On August 11, 2020,
    we ordered a modified briefing schedule as to Hunter, allowing him and his
    counsel additional time to receive and respond to disclosures of previously-
    withheld information. As of November 19, 2020, Hunter’s initial appeal was fully
    briefed, and his counsel was able to argue issues related to the Rule 33 Order and
    the initial appeal at oral argument before us on March 22, 2022.
    13 See 18 U.S.C. app. 3 § 4 (“The court, upon a sufficient showing, may
    authorize the United States to delete specified items of classified information from
    documents to be made available to the defendant through discovery under the
    Federal Rules of Criminal Procedure, to substitute a summary of the information
    for such classified documents, or to substitute a statement admitting relevant facts
    that the classified information would tend to prove. The court may permit the
    United States to make a request for such authorization in the form of a written
    statement to be inspected by the court alone.”); Fed. R. Crim. P. 16(d)(1) (“At any
    10
    In Stillwell, we described the complete procedural background,
    including a series of Orders to Show Cause that we subsequently
    issued, and a series of disclosures that followed. 14 In short, and as is
    relevant here, we vacated the District Court’s protective order and
    eventually ordered that the withheld information be disclosed, first to
    the U.S. Attorney’s Office for the SDNY, and then to defense counsel.
    The supplemental briefing and disclosure we ordered were
    completed—with some delay due to the COVID-19 pandemic—by
    December 2020. At that point, Defendants raised their Brady claims in
    our Court.
    On January 27, 2021, we issued our opinion in Stillwell,
    remanding the case to the District Court to “consider the Brady claims
    in the first instance on an appropriate post-trial motion by
    Defendants” and to “determine whether any evidence favorable to the
    Defendants was material, suppressed, or both.” 15
    time the court may, for good cause, deny, restrict, or defer discovery or inspection,
    or grant other appropriate relief. The court may permit a party to show good cause
    by a written statement that the court will inspect ex parte. If relief is granted, the
    court must preserve the entire text of the party’s statement under seal.”).

    15   Id. at 201–02.
    11
    C. Developments Post-Remand
    In the District Court, Defendants submitted motions for a new
    trial under Rule 33, making Brady claims based on the withheld
    information.
    On November 18, 2021, the District Court held a classified
    hearing on those motions.
    Defendants referred to the withheld information to advance a
    series of arguments about LeRoux and his role in their trial. Two
    categories of information are relevant to the instant arguments of
    Hunter and Stillwell on appeal.
    First, the withheld information contains what the District Court
    usefully termed “Management and Manipulation Material”—that is,
    evidence that LeRoux was in firm control of his criminal empire and
    that he was willing to deceive, manipulate, and lie in order to advance
    his own interests.
    Many documents tend to show that LeRoux took an active hand
    in managing his organization. For example, LeRoux appears to have
    required certain employees to seek his approval before acting, and
    LeRoux had several in-depth conversations with his associates about
    wire transfers and other means of moving money. Several other
    documents tend to show that LeRoux had a detailed knowledge of
    legal systems and a willingness to manipulate them. For example,
    LeRoux had discussions with his wife about an investigation he was
    then facing in Hong Kong; he mentioned the lawyers he had employed
    12
    to deal with that investigation, compared his ability to affect the
    outcome of the investigation in Hong Kong as opposed to the
    Philippines, and talked about the impact that getting a divorce might
    have on the investigation.
    Second, a particular document reflects a conversation that
    Stillwell contends is about the disposal of the Lee murder weapon. In
    the communication, LeRoux had a discussion with an unidentified
    man, who told LeRoux that he was “going to throw the candles to the
    river.” 16 LeRoux appeared to reply affirmatively, urging him to throw
    “the other steel shit” in the river. 17
    The parties also submitted information to the District Court
    about the withheld information itself, including how the government
    came by the information, what governmental entities possessed that
    information, and the relationships between those governmental
    entities and the prosecution of the legal case against Defendants.
    In particular, the Government submitted that the DEA agents
    who possessed the withheld information prior to its disclosure to the
    parties were members of the DEA’s Special Project Section (“DEA-
    SPS”), whereas the DEA agents who helped build the case against
    Defendants were members of the DEA’s Bilateral Investigations Unit
    16 Gov’t Br. Ex. B, PC #2012-79691 at 2, United States v. Hunter, No. 13-cr-521-
    RA, ECF 764. Unless otherwise noted, “Gov’t Br.” refers to the Government’s
    classified memorandum of law filed in the District Court on April 5, 2021 in
    opposition to Defendants’ Rule 33 motions on remand.
    17   Id.
    13
    (“DEA-BIU”). The Government submitted an affidavit from the
    Assistant Special Agent in Charge of the DEA-SPS explaining that
    while the DEA-SPS and DEA-BIU are both part of the DEA’s Special
    Operations Division [DEA-SOD], they are “separate and distinct” and
    “[p]ersonnel assigned to the [DEA-BIU] were not read on nor given
    access to information available to and collected by personnel assigned
    to the [DEA-SPS]” in this case. 18
    On December 14, 2021, following its classified hearing, the
    District Court issued its Rule 33 Order denying Defendants’ motions.19
    On December 28, 2021, Hunter and Stillwell filed a motion in
    our Court to recall the mandate. They simultaneously moved for us to
    vacate certain counts of conviction in light of the Supreme Court’s
    decision in United States v. Davis 20 and to remand for resentencing.
    Also on December 28, 2021, Samia filed a separate motion to
    recall the mandate in which he simultaneously moved to
    unconsolidate his appeal from that of the other two Defendants.
    On January 7, 2022, we denied the motions to recall the mandate
    as moot, noting that the District Court’s Rule 33 Order had
    automatically restored jurisdiction to our panel pursuant to our remand

    14
    order in Stillwell. 21 We denied Defendants’ motions to vacate and
    remand, and to unconsolidate, without prejudice. With the cause again
    before us, we instructed any Defendants wishing to appeal the District
    Court’s Rule 33 Order to submit supplemental letter briefs addressing
    that issue, and provided a schedule for the parties to respond and
    reply.
    That supplemental briefing was completed March 2, 2022, at
    which point all three Defendants’ fully-briefed initial appeals, as well
    as Hunter’s and Stillwell’s appeals from the Rule 33 Order, were all
    pending before our Court. On March 22, 2022 we heard oral argument.
    In a summary order filed the same day as this opinion, we
    address Defendants’ claims in their initial appeals. And we proceed in
    this opinion to examine in particular the claims of Hunter and Stillwell
    on appeal of the Rule 33 Order.
    II. DISCUSSION
    Rule 33 of the Federal Rules of Criminal Procedure provides that
    “[o]n the defendant’s motion, the court may vacate any judgment and
    grant a new trial to that defendant if the interest of justice so
    requires.” 22 On such a motion, “[t]he defendant bears the burden of
    proving that he is entitled to a new trial,” and in order to grant a new
    See Jacobson, 
    15 F.3d at 22
     (explaining a mechanism for the “automatic
    21
    restoration of appellate jurisdiction” following a remand “seek[ing]
    supplementation of the record”).
    22   Fed. R. Crim. P. 33.
    15
    trial, “a district court must find that there is a real concern that an
    innocent person may have been convicted.” 23
    As we have explained, “[w]e review challenges to a district
    court’s denial of a Rule 33 motion for an abuse of discretion and accept
    the district court’s factual findings unless they are clearly erroneous.” 24
    It is well-established by Brady and related authorities that in a
    criminal prosecution, “the government has an affirmative duty” under
    the Due Process Clause “to disclose favorable evidence known to it,
    even if no specific disclosure request is made by the defense.” 25 If this
    obligation is violated, the district court may grant a new trial. That
    said, not all instances of governmental nondisclosure violate Brady, or
    warrant        such     relief..26   “There       are   three    components     of   a
    true Brady violation: The evidence at issue must be favorable to the
    accused, either because it is exculpatory, or because it is impeaching;
    that evidence must have been suppressed by the State, either willfully
    or inadvertently; and prejudice must have ensued.” 27 In other words,

    true Brady material must be (1) favorable, (2) suppressed, and (3)
    prejudicial.
    Before the District Court and on appeal, the parties agree that
    the withheld information was “favorable” and dispute only the second
    and third points. The District Court held that the withheld information
    was neither “suppressed” within the meaning of Brady, nor
    prejudicial, and therefore denied Defendants’ motions. We address
    both of these conclusions, beginning with prejudice.
    A. Prejudice
    Under Brady, the prosecution is required to disclose evidence
    “where the evidence is material either to guilt or to punishment.” 28 To
    establish “materiality,” a defendant must show that he was prejudiced
    by the prosecution’s failure to disclose.
    Evidence is “material” within the meaning of Brady when there
    is a reasonable probability that, had the evidence been disclosed,
    the result of the proceeding would have been different. A
    “reasonable probability” of a different result is one in which the
    suppressed evidence undermines confidence in the outcome of
    the trial. In other words, [Defendants] . . . are entitled to a new
    28   Brady, 
    373 U.S. at 87
     (emphasis added).
    17
    trial only if they establish the prejudice necessary to satisfy the
    “materiality” inquiry. 29
    This inquiry presents a mixed question of law and fact. 30 “While the
    trial judge's factual conclusions as to the effect of nondisclosure are
    entitled to great weight, we examine the record de novo to determine
    whether the evidence in question is material as a matter of law.” 31 We
    conclude that neither Stillwell nor Hunter have met their burden. The
    evidence against both of them at trial, considered next to whatever
    favorable uses they might have had for the withheld information, does
    not permit us to conclude that there is a “reasonable probability” that
    even one juror would have voted to acquit either of them. 32
    Hunter and Stillwell both argue that the withheld information
    would have primarily supplied impeachment evidence against
    LeRoux. Hunter argues, for example, that “the undisclosed
    materials . . . demonstrate that LeRoux was a master at manipulating
    the system,” which, if shown to a jury, would have cast doubt on
    LeRoux’s testimony relevant to establishing the jurisdictional element

    with regard to Hunter. 33 Stillwell similarly argues that “the jury at a
    new trial through impeachment [could] conclude that LeRoux” only
    recanted his “2015 Statement” (that Stillwell was unaware of the
    purpose of his trip to the Philippines prior to his departure) in order
    to make himself a more useful government witness. 34 In other words,
    Stillwell claims the recantation was the actual lie, and this argument
    might have undermined the jurisdictional element of the prosecution’s
    case against him.
    We assess these arguments and the withheld information “in
    light of the entire record,” 35 and easily conclude, as the District Court
    did, that there was significant additional evidence against both
    Defendants, such that simply impeaching LeRoux as described would
    not have sufficed to upset the trial verdict. “Where the evidence
    against the defendant is ample or overwhelming, the withheld Brady
    material is less likely to be material than if the evidence of guilt is
    thin.” 36 Here, substantial other evidence existed to establish the
    jurisdictional elements of the conspiracy charges as to both
    Defendants, and LeRoux was already thoroughly impeached at trial.
    The District Court was therefore correct to deny the Rule 33 motions
    on remand. We examine in turn the Defendants’ arguments in the

    context of other evidence presented against them individually, and
    then generally discuss the cumulativeness of impeaching LeRoux.
    1. Hunter
    As the District Court explained in its Rule 33 Order, “[t]he
    jurisdictional case against Hunter . . . did not rest on . . . LeRoux’s
    testimony.” 37 Rather, significant additional evidence established that
    Hunter engaged in the murder conspiracy while in the U.S.
    The Government submitted evidence that Hunter had taken
    Korean Airlines flight 35 to the U.S. on December 10, 2011, and that he
    met with Samia and Stillwell later that month in North Carolina to plot
    murders-for-hire in the Philippines. That evidence included records
    from the Treasury Enforcement Communications Systems (“TECS”)
    database showing Hunter’s name and a Korean Airlines manifest
    indicating Hunter had been on the flight. It also included the
    testimony of a cooperator from LeRoux’s organization, Timothy
    Vamvakias, who testified to receiving a December 2011 call from
    Hunter from a Kentucky area-code. Vamvakias testified that Hunter
    confirmed during the phone call that he was home in Owensboro,
    Kentucky and stated that he was on his way to “Carolina” to meet with
    Samia. 38
    Defendants argued extensively at trial that Hunter was not on
    the Korean Airlines flight, and that he did not actually attend the
    37   Rule 33 Order, No. 13-cr-521-RA, ECF 796, at 14.

    December 2011 meeting. Even if we were to accept Hunter’s version of
    the evidence on the December 2011 meeting—which we cannot, given
    the “great weight” afforded the District Court’s factual findings 39—the
    Government still presented ample additional evidence to satisfy the
    jurisdictional element.
    Most critically, even though the parties at trial focused intensely
    on the North Carolina meeting based on its temporal proximity to the
    Lee murder, the Government established that Hunter began
    conspiring with LeRoux to commit murders-for-hire as early as
    December 2009. For example, the Government introduced emails from
    December 2009 between a former murder-for-hire leader in the
    LeRoux organization named David Smith, Hunter, and Samia about
    “bonus” jobs. 40 It further introduced evidence that in the time between
    December 2009 and December 2011, Hunter remained involved in
    LeRoux’s murder-for-hire conspiracy, eventually replacing Smith in a
    leadership role. 41 The Government’s evidence also showed that
    Hunter was in the U.S. at multiple points between then and his trip to
    the Philippines, notably in February 2011. 42

    21
    In other words, this was a not a case where the Government’s
    ability to establish the jurisdictional element of Hunter’s murder
    conspiracy charge depended on LeRoux’s testimony about the
    December 2011 meeting. To the contrary, in light of the Government’s
    other evidence there is no reasonable probability that disclosure
    would have caused a different result at trial.
    2. Stillwell
    Similarly, the District Court concluded in its Rule 33 Order that
    “LeRoux’s testimony at trial was not a critical aspect of the
    government’s case against Stillwell as to the jurisdictional element” of
    the conspiracy charge, 43 and we agree. As with Hunter, Stillwell’s
    presence in the U.S. when he conspired to commit murder was
    established by multiple items of evidence.
    The government submitted substantial evidence from Stillwell’s
    laptop computer, including a file titled “Hitman,” kept in a folder
    titled “Interesting Stuff,” which contained instructions on how to
    commit murder. 44 Those instructions corresponded exactly to the
    manner in which the Lee murder was carried out. These files were
    accessed—if not necessarily opened—in October 2011, prior to
    43  Rule 33 Order, No. 13-cr-521-RA, ECF 796, at 18 (brackets omitted)

    Stillwell’s and Samia’s departure from the U.S. for the Philippines. 45
    Stillwell then brought the laptop with him to the Philippines and the
    files were accessed again in February 2012, days before Lee was killed.
    The Government also provided evidence that Stillwell and
    Samia worked together closely while in the U.S. to prepare for their
    Philippines trip. This included evidence of a phone call between them
    on September 30, 2011, the same day Samia paid for Stillwell to apply
    for a passport for the first time in his life. It also included email traffic
    between Samia, Hunter, and LeRoux, discussing the timing of the
    Philippines trip in the context of when Samia’s “partner” would be
    “ready” for the two of them to “come [to the Philippines] together for
    [n]inja stuff.” 46 Stillwell essentially argues that he and Samia engaged
    in this extensive joint preparation for the Philippines, but Samia kept
    him completely in the dark as to the real reason for the trip, viz., to
    commit murder. In light of the evidence, and considering that Samia
    and Stillwell had known each other for more than seven years and
    worked closely together before, there is not a reasonable probability
    that disclosure before trial would have produced a different result.

    3. Impeaching LeRoux
    As a general matter, the withheld information was non-
    prejudicial not only because other evidence existed to establish the
    jurisdictional elements of Hunter and Stillwell’s crimes, but also
    because significant impeachment evidence against LeRoux already
    existed at trial, where he was extensively impeached. In other words,
    impeachment based on the withheld information would have been
    cumulative. 47
    As we have previously explained specifically with regard to
    withheld impeachment evidence, “a new trial is generally not required
    when the testimony of the witness is corroborated by other testimony,
    or when the suppressed impeachment evidence merely furnishes an
    additional basis on which to impeach a witness whose credibility has
    already been shown to be questionable.” 48 In LeRoux’s case, the
    evidence at trial left little doubt that he was untrustworthy. For
    example, the “2015 Statement”—and LeRoux’s recantation of it—was
    the subject of close cross-examination by attorneys for several of the
    Defendants. 49
    Attorneys for the Government and several Defendants also
    cross-examined LeRoux about his vast international criminal
    47  See United States v. Avellino, 
    136 F.3d 249
    , 257 (2d Cir. 1998)
    (“[U]ndisclosed evidence may be cumulative, and hence not material.”).

    24
    organization. During the course of that testimony, LeRoux admitted to
    a host of deceitful and manipulative acts, including murdering a
    witness; framing individuals for crimes they did not commit; bribing
    multiple foreign authorities, including a judge; and attempting to
    secure diplomatic privileges for himself by supporting a coup in the
    Seychelles. And all of this is to say nothing of the litany of generally
    violent and nefarious acts to which he also admitted, including
    arranging for numerous other murders; personally committing
    murder; extensive trafficking in weapons and narcotics; and dealing
    in weapons with Iran and North Korea. Hunter and Stillwell would
    have us believe that additional evidence merely demonstrating that
    LeRoux was a liar, manipulative, or a perjurer would somehow have
    been the straw that broke the camel’s back with the jury—finally
    causing them to distrust Paul LeRoux. We are unpersuaded. 50
    50 Our conclusion is unaltered by Stillwell’s argument that the withheld
    information would have shown that LeRoux perjured himself at trial. Stillwell
    refers to an instance where an unidentified person tells LeRoux that he will “throw
    the candles to the river.” Gov’t Br. Ex. B, PC #2012-79691, at 2. LeRoux agrees, and
    urges his interlocutor to throw “the other steel shit” in the river. 
    Id.
     Stillwell claims
    that LeRoux and his interlocutor are discussing the disposal of the Lee murder
    weapon, that LeRoux therefore perjured himself when he testified at trial that the
    weapon was returned to a warehouse, and that the nondisclosure prejudiced
    Stillwell by preventing him from making this argument to the jury.
    We disagree. Stillwell’s argument under Brady requires multiple
    assumptions, including that the word “candles” as used in the communication
    meant guns and that the guns at issue included the Lee murder weapon. This,
    despite the fact there was no concrete connection between LeRoux’s interlocutor
    and the Lee murder, and three months had elapsed between the Lee murder and
    the communication. LeRoux’s criminal network and dealings were extensive. The
    25
    In sum, we recall that, “strictly speaking, there is never a real
    ‘Brady violation’ unless the nondisclosure was so serious that there is
    a reasonable probability that the suppressed evidence would have
    produced a different verdict.” 51 The withheld information would not
    have produced a different verdict here, it was not “material” under
    Brady, and the District Court on remand was right to deny Defendants’
    Rule 33 motions.
    B. Suppression
    Because we have determined that the withheld information was
    not “material,” we need not determine whether it was “suppressed”
    in order to decide this appeal. 52 Still, because the District Court
    concluded that Defendants established neither materiality nor
    suppression, we briefly examine the latter conclusion. 53
    assumptions required to make this communication relevant to the Lee murder and
    Stillwell’s case are not particularly persuasive, especially when taken together.
    51 See Strickler, 
    527 U.S. at 281
    ; United States v. Coppa, 
    267 F.3d 132
    , 140 (2d
    Cir. 2001).
    52  See, e.g., United States v. Gonzalez, 
    110 F.3d 936
    , 944 (2d Cir. 1997) (“We
    need not decide whether or not the evidence was suppressed, however, because we
    believe, in any event, that the evidence was not material.”).
    53Rule 33 Order, No. 13-cr-521-RA, ECF 796, at 33 (“Defendants have failed
    to demonstrate the suppression of evidence or materiality necessary to establish a
    Brady violation.”).
    26
    “The Brady obligation extends only to material evidence . . . that
    is known to the prosecutor.” 54 Because “the prosecution . . . alone can
    know what is undisclosed,” it “must be assigned the consequent
    responsibility to gauge the likely net effect of [undisclosed] evidence
    and make disclosure when the point of ‘reasonable probability’ is
    reached.” 55 In other words, the onus is naturally on the prosecutor to
    determine what must be disclosed. The Supreme Court has thus
    counseled several times that “the prudent prosecutor will resolve
    doubtful questions in favor of disclosure.” 56
    Moreover, as the Supreme Court explained in Kyles v. Whitley, 57
    the fact that the prosecutor has a monopoly on potentially material
    information prior to its disclosure imposes a further burden: “the
    individual prosecutor has a duty to learn of any favorable evidence
    known to the others acting on the government’s behalf in the case,
    including the police.” 58
    But who is “acting on the government’s behalf” in a case?
    Indeed, we have previously observed that answering this question

    defies “a broad, categorial approach,” and instead requires us to
    “examin[e] the specific circumstances of the person alleged to be an
    ‘arm of the prosecutor,’” 59 or, as we have also articulated it, part of the
    “prosecution team.” 60
    We have long rejected the notion that “knowledge of any part of
    the government is equivalent to knowledge on the part of th[e]
    prosecutor.” 61 And this circumscription on the Kyles duty is ultimately
    grounded in a prudential concern:
    [K]nowledge on the part of persons employed by a different
    office of the government does not in all instances warrant the
    imputation of knowledge to the prosecutor, for the imposition
    of an unlimited duty on a prosecutor to inquire of other offices
    not working with the prosecutor’s office on the case in question
    would inappropriately require us to adopt “a monolithic view
    of government” that would “condemn the prosecution of
    criminal cases to a state of paralysis.” 62

    Thus, while a prosecutor has a duty under Kyles to learn information
    when that information is possessed by others on the “prosecution
    team,” undisclosed information that is not known to anyone on that
    team does not give rise to a Brady violation. 63
    We have also made clear that the imputation of knowledge to
    the prosecutor “does not turn on the status of the person with actual
    knowledge, such as a law enforcement officer, prosecutor or other
    government official. In other words, the relevant inquiry is what the
    person did, not who the person is.” 64
    We discussed this point in United States v. Locascio, 65 a case in
    which a team of prosecutors in the U.S. Attorney’s Office for the
    Eastern District of New York (“EDNY”) entered into a plea bargain
    with Salvatore Gravano, the consigliere of the Gambino crime family
    and a cooperator. In his plea, he stated that he had admitted to all the
    crimes he had committed. Gravano subsequently testified at the trial
    of Gambino crime family “boss” John Gotti and “underboss” Frank
    Locascio.
    FBI reports prepared by agents working in another district
    contained evidence that Gravano had, in fact, committed other crimes,
    in addition to those to which he had confessed. The work of those

    agents and the existence of their reports were entirely unknown to the
    EDNY prosecution team throughout their prosecution of Gotti and
    Locascio. After sentencing, an EDNY prosecutor encountered the
    reports, confirmed no one on his prosecution team had been aware of
    them, and disclosed them to counsel for Gotti and Locascio. They then
    filed a motion for a new trial, arguing that the government had
    suppressed favorable, material information in violation of Brady. We
    affirmed the district court’s denial of that motion because “there [was]
    no evidence that the prosecution team . . . was aware of the reports that
    ha[d] subsequently come to light.” 66
    The District Court here, relying in part on Locasio, held that this
    was the sort of situation that faced the SDNY U.S. Attorney’s Office.
    Indeed, we understand the position of the SDNY prosecutors, and also
    their frustration—the protective order sought and obtained by the
    Washington-based NDDS from the District Court specifically barred
    the disclosure of the withheld information to prosecutors from that
    office.
    The harder question, however, is whether the NDDS—and the
    DEA agents in the DEA-SPS who possessed the undisclosed
    information—should themselves be considered part of the prosecution
    team, SDNY’s position to the contrary notwithstanding.
    We disagree with Defendants’ suggestion that the question
    should be answered in the affirmative because “the DEA-BIU . . . and
    66   Locascio, 
    6 F.3d at 949
    .
    30
    the DEA-SPS . . . are part of the same subdivision of the DEA, i.e.[,] the
    DEA-SOD.” 67 This “bureaucratic proximity” argument may be
    relevant in other circumstances, but as a general matter, and as applied
    in this case, it tells us little about the actual relationship between the
    prosecutors on the one hand, and the agencies, divisions, and
    subdivisions at issue, on the other. 68 Relying solely on bureaucratic
    proximity would ultimately undercut our clear pronouncement in
    Stewart that “the relevant inquiry is what the person did, not who the
    person is.” 69
    However, Stewart simultaneously informs our skepticism that
    the withheld material was not “suppressed.” If we are to look at what
    the DEA-SPS and attorneys from the NDDS actually did, then we
    should start—most obviously—with their decision to approach the
    District Court and seek a protective order for their withheld
    information.
    Limiting disclosure obligations to the “prosecution team”
    prudently prevents a prosecutor from needing to search the “whole-
    of-government” for possibly material information in myriad cases and
    controversies before the courts. Such an obligation would clearly be an
    unworkable encumbrance on the system of justice. Whether an item of

    information is material is the sort of thing a member of the
    “prosecution team” can (and must) know—not the sort of thing a far-
    flung member of the executive branch can (or can be expected to)
    know. Here, though, such concerns about the NDDS’s ability to
    determine its own relevance, and that of the information in the DEA-
    SPS’s possession, are not present, because it was the NDDS that
    approached the court. Unexpected and unbidden, they—in effect—
    proclaimed their relevance. And despite that, they then asked the
    courts to approve their nondisclosure. Clearly someone at NDDS
    thought they or their information might be relevant in the case
    pending in the SDNY, or they would not have thought to come to the
    District Court (or us) ex parte and in camera at all.
    In this published opinion, we express our doubt that the
    NDDS—or any similarly-situated organ of the executive branch, for
    that matter—having stepped out of the shadows at least to the extent
    of asking the judiciary to bless its act of nondisclosure, even from local
    prosecutors and agents in the case, could then successfully draw a
    curtain of secrecy over “evidence . . . material either to guilt or to
    punishment” by invoking our Brady jurisprudence.
    To the extent filings and arguments before the District Court
    suggest that the NDDS, in the normal course of its business, seeks
    protective orders such as the one at issue here, we are troubled. By
    contrast, we were encouraged to learn from SDNY prosecutors at the
    most recent oral argument in our Court on this matter that our
    message of concern “has been delivered both to the Department of
    Justice and to the NDDS by the executive leadership” of the SDNY,
    32
    and that “the message has been received.” Oral Arg. at 48:20-40. As we
    suggested in Stillwell and re-affirm here, we strongly question
    whether—had          the    withheld      information        been     material—our
    jurisprudence circumscribing the “prosecution team” would have
    been adequate to protect Defendants’ rights in the circumstances
    presented here. 70
    Ultimately, however, we raise this question only by way of
    caveat. It is clearly not necessary for us to answer this question today.
    Because we have firmly concluded that the withheld information was
    not prejudicial, it was not “material” information under Brady, and we
    are able to affirm the District Court’s Rule 33 Order on that basis.
    70  This is not the first time our court and district courts in this circuit have
    raised such concern. See United States v. Zagari, 
    111 F.3d 307
    , 320 n. 13 (2d Cir. 1997)
    (“The extent to which knowledge may be imputed from one federal investigative
    agency to another for Brady purposes is as yet unclear.”); see also United States v.
    Morgan, 
    302 F.R.D. 300
    , 304 (S.D.N.Y. 2014) (“There is no clear test to determine
    whether or not an individual or agency is a member of the prosecution team.”);
    United States v. Meregildo, 
    920 F. Supp. 2d 434
    , 441 (S.D.N.Y. 2013) (same); United
    States v. Bin Laden, 
    397 F. Supp. 2d 434
    , 484 (S.D.N.Y. 2013) (noting the Second
    Circuit is “lacking a clearly articulated imputation test”); Chandras v. McGinnis, No.
    01 Civ. 2519(LBS), 
    2002 WL 31946711
    , at *7 (E.D.N.Y. Nov. 13, 2002) (“[T]he exact
    point at which government agents can fairly be categorized as acting on behalf of
    the prosecution . . . is uncertain.”). One has only to imagine the information in
    NDDS’s possession being actually exculpatory rather than cumulatively
    impeaching to bring this concern into sharp relief.

    III. CONCLUSION
    To summarize:
    1. We hold that the withheld information was not
    prejudicial,   and   it    was   therefore   not   “material”
    information under Brady.
    2. We AFFIRM the District Court’s December 14, 2021 order
    denying Defendants’ Rule 33 motions for a new trial.
    3. The cause is REMANDED for resentencing, pursuant to
    the summary order entered the same day this opinion is
    filed, for reasons explained in that summary order.
