    service. The Constitution and laws of the United States, however, deny him
    that power.
    At the Founding, few issues garnered more attention and debate than
    did the Constitution’s allocation of power over the military. The Federalists
    and Anti-Federalists feared that a standing army would lead ineluctably to
    tyranny. The Founders also recognized, however, that our then-fledgling
    Nation needed a strong national defense. The Constitution’s solution to this
    dilemma is embodied in its Militia Clauses. Those clauses reflect a delicate
    compromise that gives the States power over their respective militias—
    subject to the President’s power to call those militias into national service
    when necessary.
    In this case, President Biden imposed and then repealed a mandate
    requiring State militiamen to take the COVID-19 vaccine. And now that the
    President has rescinded the vaccine requirement, he wants to retain the
    power to punish militia members who refused to get the shots while the
    mandate was in effect—all without calling them into national service. We
    reject the President’s assertion of power because it would undermine one of
    the most important compromises in the Constitution. If the Constitution’s
    text, history, and tradition make anything clear, it’s that the President can
    punish members of the Texas militia only after calling them into federal
    service.
    It’s also important to clarify at the outset what this case is not about.
    This is not a case about “military readiness.” The Government repeatedly
    emphasizes that our national government has set military readiness standards
    since the Founding. That’s equal parts true and irrelevant. It’s of course true,
    for example, that Congress in 1792 adopted Baron von Steuben’s “Rules of
    Discipline,” which included a host of military instructions intended to make
    militias ready for national service if and when called to perform it. But it’s
    2
    Case: 22-40399      Document: 00516783843           Page: 3    Date Filed: 06/12/2023
    No. 22-40399
    equally true that the States—and the States alone—retained power to
    implement those readiness requirements. And crucially, the States—and the
    States alone—retained power to punish members of their militias who fell
    short of those standards. Thus, while it appears common ground between the
    parties that the President can impose vaccine requirements as part of the
    national effort to ensure military readiness, only the States can punish non-
    federalized Guardsmen who fall short of that standard. That’s especially true
    in this case because the Secretary of Defense conceded that COVID shots are
    no longer necessary to military readiness when he repealed the mandate.
    I.
    A.
    The relationship among the National Guard, the States, and the
    federal military is complex. See Perpich v. Dep’t of Def., 
    496 U.S. 334
     (1990).
    But in broad strokes, the National Guard includes two “overlapping but
    distinct organizations”—the National Guards of the various States and the
    National Guard of the United States. 
    Id. at 345
    . All who enlist in a State’s
    National Guard must simultaneously enlist in the National Guard of the
    United States, ibid., which is a “reserve component[] of the armed forces,”
    
    10 U.S.C. § 10101
    . Although the State National Guard is funded largely by
    the federal government, “the Governor remains in charge of the National
    Guard in each [S]tate except when the Guard is called into active federal
    service.” Holdiness v. Stroud, 
    808 F.2d 417
    , 421 (5th Cir. 1987); see also, e.g.,
    Blackwell v. United States, 
    321 F.2d 96
    , 98 (5th Cir. 1963) (“The rule is well
    established that a member of the National Guard who . . . has not been called
    into federal service is not an employee of the United States within the
    meaning of the Federal Tort Claims Act.”).
    The State of Texas, for example, trains members of the Texas
    National Guard (which we refer to as the “Texas militia” or “Texas
    3
    Case: 22-40399         Document: 00516783843                Page: 4       Date Filed: 06/12/2023

    Guard”) and appoints its officers. U.S. Const. art. I, § 8, cl. 15; Tex.
    Gov’t Code § 437.003(c); 
    32 U.S.C. §§ 501
    –02. The Governor also
    retains the authority to activate the State’s Guardsmen to assist with State
    missions (such as responding to natural disasters, riots, terrorist attacks,
    &c.). See 
    38 U.S.C. § 4303
    (15); Tex. Gov’t Code §§ 437.004–.005. That
    is why we’ve said “the [N]ational [G]uard is the militia, in modern-day form,
    that is reserved to the [S]tates by Art. I § 8, cls. 15, 16 of the Constitution.”
    Lipscomb v. FLRA, 
    333 F.3d 611
    , 613 (5th Cir. 2003).1 It’s also why Texas law
    recognizes the Governor as “Commander-in-Chief of the military forces of
    the State.” Tex. Const. art. IV, § 7; see also Tex. Gov’t Code
    § 437.001(14).
    The President of the United States is Commander in Chief of the
    United States Armed Forces at all times. He’s Commander in Chief of the
    National Guard of the United States at all times. But he’s Commander in
    Chief of the State Guards only at limited times. Specifically, the President
    becomes “Commander in Chief . . . of the Militia of the several States, when
    called into the actual Service of the United States.” U.S. Const. art. II, § 2,
    cl. 1 (emphasis added); see also Tex. Const. art. IV, § 7 (“[The Governor]
    shall be Commander-in-Chief of the military forces of the State, except when
    1
    The Texas “State militia” also includes the “reserve militia,” which is comprised
    of “persons liable to serve, but not serving, in the state military forces.” Tex. Gov’t
    Code § 431.001(1); see also id. § 431.001(3) (“‘State military forces’ means the Texas
    National Guard, the Texas State Guard, and any other active militia or military force
    organized under state law.”). The “State militia” likewise includes the Texas State
    Guard—“the volunteer military forces that provide community service and emergency
    response activities for th[e] [S]tate.” Id. § 437.001(16); see also id. § 437.001(14); 
    32 U.S.C. § 109
    (c) (authorizing States to “organize and maintain defense forces” to be “used within
    the jurisdiction concerned”). The Texas State Guard is not part of the Texas National
    Guard and is not federally funded. Nor may it be “called, ordered, or drafted into the armed
    forces.” 
    32 U.S.C. § 109
    (c). The Government’s COVID-19 vaccine mandate does not
    apply to either the reserve militia or the Texas State Guard.

    Case: 22-40399        Document: 00516783843             Page: 5      Date Filed: 06/12/2023
    No. 22-40399
    they are called into actual service of the United States.” (emphasis added)). The
    Constitution in turn assigns Congress the power “[t]o provide for calling
    forth the Militia to execute the Laws of the Union, suppress Insurrections
    and repel Invasions.” U.S. Const. art. I, § 8, cl. 15. And when the
    President calls the State Guards into the service of the United States—
    colloquially termed “federalizing”—those Guardsmen temporarily become
    part of the Army and Air Force. See 
    10 U.S.C. §§ 10106
    , 10112.
    B.
    On August 24, 2021, the Secretary of Defense ordered all members of
    the military to take COVID vaccines. “[W]ith the support of the President,”
    Secretary of Defense Lloyd Austin “direct[ed] the Secretaries of the Military
    Departments to immediately begin full vaccination of all members of the
    Armed Forces under DoD authority on active duty or in the Ready Reserve,
    including the National Guard.” Memorandum, Secretary of Defense,
    Mandatory Coronavirus Disease 2019 Vaccination of Department of Defense
    Service Members (Aug. 24, 2021) (emphasis added). Secretary Austin
    explained that “[t]o defend this Nation, we need a healthy and ready force.”
    Ibid.2
    The next day, on August 25, 2021, Texas Governor Greg Abbott
    issued Executive Order GA-39. He commanded that “on a statewide basis
    2
    The Constitution gives Congress the power “[t]o provide for organizing, arming,
    and disciplining, the Militia, and for governing such Part of them as may be employed in
    the Service of the United States.” U.S. Const. art. I, § 8, cl. 16. And Congress, in turn,
    gave the President the power to “prescribe regulations, and issue orders, necessary to
    organize, discipline, and govern the National Guard.” 
    32 U.S.C. § 110
    ; see also 
    10 U.S.C. § 10202
    (a) (“Subject to standards, policies, and procedures prescribed by the Secretary of
    Defense, the Secretary of each military department shall prescribe such regulations as the
    Secretary considers necessary to carry out provisions of law relating to the reserve
    components under the Secretary’s jurisdiction.”). Here, the Department of Defense is
    exercising that authority on behalf of the President.
    5
    Case: 22-40399        Document: 00516783843             Page: 6      Date Filed: 06/12/2023
    No. 22-40399
    . . . [n]o governmental entity can compel any individual to receive a COVID-
    19 vaccine.” Under his power as Commander in Chief of the State’s military
    forces, Governor Abbott later clarified that GA-39 applies to all members of
    Texas’s militia, including the Texas National Guard.
    On November 30, 2021, Secretary Austin directed the Army and Air
    Force to create “policies and implementation guidance to address the failure
    to maintain this military medical readiness requirement by members of the
    non-federalized National Guard who remain unvaccinated.” Memorandum,
    Secretary of Defense, Coronavirus Disease 2019 Vaccination for Members of
    the National Guard and the Ready Reserve (Nov. 30, 2021). The
    Government eventually threatened five consequences against noncompliant
    Guardsmen and States (collectively, “the enforcement measures”):
    (1) Courts-martial. 
    32 U.S.C. §§ 326
    –27.
    (2) Discharge from the National Guard. 
    Id.
     §§ 322–24.
    (3) Prohibiting Guardsmen from participating in drills,
    training, and other duties. Id. §§ 501–02.
    (4) Withholding pay from individual Guardsmen. Id. § 108.
    (5) Withholding funds from individual States. Ibid.
    Governor Abbott filed suit on January 4, 2022.3 He alleged that the
    military vaccine mandate is arbitrary and capricious within the meaning of
    the Administrative Procedure Act (“APA”). He also alleged that all but one
    of the Government’s planned enforcement measures violate the
    Constitution. For relief, Governor Abbott sought an order declaring the
    vaccination requirement and the challenged enforcement measures unlawful,
    3
    Alaska Governor Mike Dunleavy joined the suit. Governor Dunleavy is not a party
    to this appeal, however.
    6
    Case: 22-40399      Document: 00516783843           Page: 7   Date Filed: 06/12/2023
    No. 22-40399
    setting them aside, and enjoining their enforcement as to non-federalized
    Guardsmen. He also requested costs, attorneys’ fees, and any other relief the
    court deems proper.
    Governor Abbott then moved for an order preliminarily enjoining the
    defendants from enforcing the vaccine mandate against members of the
    Texas militia not in federal service. The district court denied the motion. The
    Governor appealed under 
    28 U.S.C. § 1292
    (a)(1).
    After our court heard oral argument, President Biden and Congress
    directed Secretary Austin to rescind the COVID vaccine mandate for
    military service members. See James M. Inhofe National Defense
    Authorization Act for Fiscal Year 2023, 
    Pub. L. No. 117-263, § 525
    , 
    136 Stat. 2395
    , 2571–72 (2022). On January 10, 2023, Secretary Austin rescinded his
    earlier memos. Memorandum, Secretary of Defense, Rescission of August
    24, 2021, and November 30, 2021, Coronavirus Disease 2019 Vaccination
    Requirements for Members of the Armed Forces (Jan. 10, 2023). He left
    undisturbed “[o]ther standing Departmental policies, procedures, and
    processes regarding immunizations.” 
    Ibid.
     And he also clarified that “[n]o
    individuals currently serving in the Armed Forces shall be separated solely
    on the basis of their refusal to receive the COVID-19 vaccination if they
    sought an accommodation on religious, administrative, or medical grounds.”

    “Jurisdiction is always first.” Carswell v. Camp, 
    54 F.4th 307
    , 310 (5th
    Cir. 2022) (quotation omitted). Mootness is a jurisdictional question because
    “[t]he inability of the federal judiciary to review moot cases derives from the
    requirement of Art. III of the Constitution under which the exercise of
    judicial power depends upon the existence of a case or controversy.” DeFunis
    v. Odegaard, 
    416 U.S. 312
    , 316 (1974) (per curiam) (quotation omitted).

    Case: 22-40399      Document: 00516783843           Page: 8    Date Filed: 06/12/2023
    No. 22-40399
    To invoke the jurisdiction of the federal courts under Article III, a
    plaintiff “must have suffered, or be threatened with, an actual injury
    traceable to the defendant and likely to be redressed by a favorable judicial
    decision.” Lewis v. Cont’l Bank Corp., 
    494 U.S. 472
    , 477 (1990). That’s
    standing. The mootness doctrine, by contrast, requires that a plaintiff’s
    interest in a suit “exist[] throughout the proceedings.” Uzuegbunam v.
    Preczewski, 
    141 S. Ct. 792
    , 796 (2021). That means a case becomes moot
    “when it is impossible for a court to grant ‘any effectual relief whatever to
    the prevailing party.’” Knox v. Serv. Emps. Int’l Union, Local 1000, 
    567 U.S. 298
    , 307 (2012) (quoting Erie v. Pap’s A.M., 
    529 U.S. 277
    , 287 (2000)).
    The Government claims this appeal is moot. That’s so, it says,
    because Governor Abbott seeks to enjoin the Government from enforcing the
    vaccine mandate against Texas’s militia; but after Governor Abbott filed suit,
    President Biden signed into law a statute that ordered Secretary Austin to
    rescind that very mandate. See § 525, 136 Stat. at 2571–72 (“Not later than
    30 days after the date of the enactment of this Act, the Secretary of Defense
    shall rescind the mandate that members of the Armed Forces be vaccinated
    against COVID-19.”). The Government asserts that “[b]ecause the Texas
    National Guard is no longer subject to the challenged requirement, Governor
    Abbott has obtained all the relief that he sought in this appeal.”
    If that were true, it would very likely moot this appeal. See, e.g., Spell
    v. Edwards, 
    962 F.3d 175
    , 179 (5th Cir. 2020) (“[A] case challenging a statute,
    executive order, or local ordinance usually becomes moot if the challenged
    law has expired or been repealed.”); Amawi v. Paxton, 
    956 F.3d 816
    , 821–22
    (5th Cir. 2020) (holding the case moot because an intervening law “provided
    the plaintiffs the very relief their lawsuit sought”). But it’s not true.
    Secretary Austin did not simply rescind the vaccine mandate and all related
    enforcement measures. Instead, he reserved the ability to punish Guardsmen
    who didn’t seek a religious, administrative, or medical accommodation while
    8
    Case: 22-40399      Document: 00516783843           Page: 9    Date Filed: 06/12/2023
    No. 22-40399
    the mandate was operative. See Memorandum, Secretary of Defense,
    Rescission of August 24, 2021 and November 30, 2021 Coronavirus Disease
    2019 Vaccination Requirements for Members of the Armed Forces (Jan. 10,
    2023); see also Leo Shane III, Troops Who Refused COVID Vaccines Still
    Could Face Punishment, Military Times (Feb. 28, 2023), https://www.
    militarytimes.com/news/coronavirus/2023/02/28/troops-who-refused-
    covid-vaccines-still-could-face-punishment/. According to Major General
    Thomas Suelzer—Adjunct General of the Texas National Guard—over
    1,000 Texas Guardsmen remain unvaccinated, never sought an
    accommodation while the mandate was in effect, and hence remain under
    Secretary Austin’s Damoclean sword.
    As such, many Texas militiamen still face the same enforcement
    measures that Governor Abbott seeks to enjoin. This appeal therefore isn’t
    moot because we can still grant “effectual relief.” Pap’s A.M., 
    529 U.S. at 287
     (quotation omitted); see also Dailey v. Vought Aircraft Co., 
    141 F.3d 224
    ,
    226–29 (5th Cir. 1998); First Nat’l Bank of Lamarque v. Smith, 
    610 F.2d 1258
    ,
    1262–63 (5th Cir. 1980). We therefore have jurisdiction.
    III.
    We turn to the preliminary injunction. “A preliminary injunction is an
    extraordinary remedy never awarded as of right.” Winter v. Nat. Res. Def.
    Council, 
    555 U.S. 7
    , 24 (2008). “A plaintiff seeking a preliminary injunction
    must establish that he is likely to succeed on the merits, that he is likely to
    suffer irreparable harm in the absence of preliminary relief, that the balance
    of equities tips in his favor, and that an injunction is in the public interest.”
    
    Id. at 20
    . “[T]he ultimate decision whether to grant or deny a preliminary
    injunction is reviewed only for abuse of discretion.” Speaks v. Kruse, 
    445 F.3d 396
    , 399 (5th Cir. 2006) (quotation omitted). But “a decision grounded in
    erroneous legal principles is reviewed de novo,” ibid., and factual findings are
    9
    Case: 22-40399     Document: 00516783843            Page: 10    Date Filed: 06/12/2023
    No. 22-40399
    reviewed for clear error, Texans for Free Enter. v. Tex. Ethics Comm’n, 
    732 F.3d 535
    , 537 (5th Cir. 2013).
    The only factor the district court considered is likelihood of success
    on the merits. Governor Abbott asserts (A) an APA challenge and (B) a
    constitutional one. We remand as to both so the district court can apply the
    correct legal standards.
    A.
    We first must ensure that Governor Abbott’s APA claims are
    justiciable. See Meister v. Tex. Adjutant Gen.’s Dep’t, 
    233 F.3d 332
    , 335 (5th
    Cir. 2000). The Government could have argued (but failed to argue) that the
    Governor’s APA claims are non-justiciable because the APA explicitly carves
    out from its coverage “a military or foreign affairs function of the United
    States.” See 
    5 U.S.C. § 553
    (a)(1) (rulemaking); accord 
    id.
     § 554(a)(4)
    (adjudication). The APA also carves out decisions that are “committed to
    agency discretion by law.” Id. § 701(a)(2).
    These carveouts are forfeitable. That’s because, where the carveouts
    apply, they deprive a would-be APA plaintiff of his cause of action; and
    arguments against a plaintiff’s cause of action go to the forfeitable merits, not
    non-forfeitable jurisdiction. See Air Courier Conf. of Am. v. Am. Postal Workers
    Union AFL-CIO, 
    498 U.S. 517
    , 517 n.3 (1991); see also Steel Co. v. Citizens for
    a Better Env’t, 
    523 U.S. 83
    , 89 (1998); Bell v. Hood, 
    327 U.S. 678
    , 682 (1946)
    (“Jurisdiction, therefore, is not defeated . . . by the possibility that the
    averments might fail to state a cause of action on which petitioners could
    actually recover. For it is well settled that the failure to state a proper cause
    of action calls for a judgment on the merits and not for a dismissal for want of
    jurisdiction.”). By invoking neither carveout, the Government forfeited both.
    Hamer v. Neighborhood Hous. Servs. of Chicago, 
    138 S. Ct. 13
    , 17 (2017)
    10
    Case: 22-40399      Document: 00516783843          Page: 11   Date Filed: 06/12/2023
    No. 22-40399
    (discussing forfeiture of non-jurisdictional defects). We therefore hold the
    case is justiciable.
    Assured that Governor Abbott’s APA claims are justiciable, we turn
    to the applicable standards. The APA instructs courts to “hold unlawful and
    set aside” agency actions that are “arbitrary” or “capricious.” 
    5 U.S.C. § 706
    (2)(A). This so-called “arbitrary-and-capricious standard requires that
    agency action be reasonable and reasonably explained.” FCC v. Prometheus
    Radio Project, 
    141 S. Ct. 1150
    , 1158 (2021); see also Wages & White Lion Invs.,
    LLC v. FDA, 
    16 F.4th 1130
    , 1136 (5th Cir. 2021) (“We must not ‘substitute’
    our ‘own policy judgment for that of the agency.’ Still, we must ensure that
    ‘the agency has acted within a zone of reasonableness and, in particular, has
    reasonably considered the relevant issues and reasonably explained the
    decision.’” (quoting Prometheus, 141 S. Ct. at 1158)). For example, courts
    must set aside agency actions that lack “a rational connection between the
    facts found and the choice made,” Motor Vehicle Mfrs. Ass’n v. State Farm
    Mut. Ins., 
    463 U.S. 29
    , 43 (1983) (quotation omitted), contain “unexplained

    a structural injunction—“a broad call on judicial power to assume continuing

    are obviously inappropriate because they transgress the Constitution’s limits
    on the judicial power. See Gilligan, 
    413 U.S. at
    8–10.
    Governor Abbott’s request is far more modest. He does not request a
    structural injunction or a nationwide one. He also does not request any relief
    that would inhibit the President’s power over the federalized Guard. Rather,
    he asks only to protect the Guardsmen who are in the State’s service from
    unlawful regulation by a President who has not federalized them. This is far
    afield from Gilligan.
    The district court concluded otherwise. It briefly mentioned the APA
    and then cited Gilligan for the proposition that “[j]udgments about military
    readiness . . . warrant particular humility in judicial review.” The court then
    pointed to Secretary Austin’s statements regarding a “healthy” military.4
    From this, the district court concluded: “Federal officials simply balanced
    the policy interests differently than would Governor Abbott.”
    The APA requires more. As the Governor argued:
    Defendants “entirely failed to consider an important aspect of
    the problem,” Motor Veh. Mfrs. Assn. v. State Farm Mut. Auto.
    Ins. Co., 
    463 U.S. 29
    , 43 (1983): Guardsmen are not a mere
    supplement to the federal military, but a vital part of each
    State’s ability to secure its citizens’ property, liberty, and
    lives—a vitality that is sapped by drumming Guardsmen out of
    militia service. The Defendants’ failure to weigh those
    considerations before upending the Texas National Guard’s
    chain of command requires that the Enforcement Memoranda
    be set aside.
    4
    Specifically, Secretary Austin said: “To defend this Nation, we need a healthy
    and ready force,” “Vaccination is essential to the health and readiness of the Force,” and
    “Vaccination of the Force will save lives and is essential to our readiness.”

    We remand the Governor’s APA claims so the district court can
    consider these points more fully.
    B.
    Next the Constitution. Governor Abbott acknowledges that Congress
    can set readiness requirements for the Texas Guard. And he further
    recognizes that the erstwhile COVID vaccine mandate was one such
    requirement. But the Governor argues that the Constitution forbids the
    Government from stepping into his shoes and directly enforcing readiness
    requirements against non-federalized Guardsmen. We agree. Unless and until
    the Texas militia is federalized, Governor Abbott retains exclusive authority
    to punish his militiamen and otherwise govern them. That’s because (1) the
    Constitution’s text clearly says so, and (2) Founding-era history reinforces
    that straightforward reading of the text.
    1.
    “[O]ur duty [is] to interpret the Constitution in light of its text,
    structure, and original understanding”—as informed by history and
    tradition. NLRB v. Noel Canning, 
    573 U.S. 513

    142 S. Ct. 2111 (2022)
     (evaluating text, history, and tradition). Here, as in all of law, text
    is king. See Martin v. Hunter’s Lessee, 
    14 U.S. (1 Wheat.) 304
    , 338–39 (1816)

    142 S. Ct. 2228
    , 2244–45 (2022)
    (“Constitutional analysis must begin with ‘the language of the instrument,’
    which offers a ‘fixed standard’ for ascertaining what our founding document

    , 186–89 (1824);
    then quoting        1   Joseph    Story,     Commentaries            on    the
    Constitution of the United States § 399 (1833))); Bruen, 142 S.
    Ct. at 2137 (“[T]o the extent later history contradicts what the text says, the
    text controls.”).
    Here, the relevant text appears in the Constitution’s two Militia
    Clauses. You might reasonably wonder why a case about the National Guard
    turns on constitutional provisions governing the militia. The answer: “[T]he
    [N]ational [G]uard is the militia, in modern-day form, that is reserved to the
    [S]tates by Art. I § 8, cls. 15, 16 of the Constitution.” Lipscomb, 
    333 F.3d at 613
    ; accord Maryland ex rel. Levin v. United States, 
    381 U.S. 41
    , 46, vacated on
    other grounds, 
    382 U.S. 159
     (1965) (“The National Guard is the modern
    Militia reserved to the States by Art. I, § 8, cl[s]. 15, 16, of the
    Constitution.”).
    Accordingly, both the Government and Governor Abbott agree that
    Clauses 15 and 16 of Article I, Section 8 directly control this dispute. We refer
    to the first of these as the “Calling Forth Clause”; it assigns Congress the
    power:
    To provide for calling forth the Militia to execute the Laws of
    the Union, suppress Insurrections and repel Invasions[.]
    U.S. Const. art. I, § 8, cl. 15. We refer to the second relevant clause as the
    “Organizing Clause”; it assigns Congress the power:
    14
    Case: 22-40399          Document: 00516783843              Page: 15       Date Filed: 06/12/2023
    No. 22-40399
    To provide for organizing, arming, and disciplining, the
    Militia, and for governing such Part of them as may be
    employed in the Service of the United States, reserving to the
    States respectively, the Appointment of the Officers, and the
    Authority of training the Militia according to the discipline
    prescribed by Congress[.]
    U.S. Const. art. I, § 8, cl. 16;5 see also 
    32 U.S.C. § 110.6
    Altogether, the Calling Forth and Organizing Clauses empower
    Congress to provide for “organizing,” “arming,” and “disciplining” the
    militia at all times; Congress can also provide for “governing” the militia, but
    only when the militia is federalized. U.S. Const. art. I, § 8, cls. 15, 16
    (emphasis added). The States, by contrast, retain exclusive power to appoint
    5
    The militia is mentioned three other times in the Constitution. See U.S. Const.
    art. II, § 2, cl. 1 (“The President shall be Commander in Chief of the Army and Navy of
    the United States, and of the Militia of the several States, when called into the actual
    Service of the United States[.]”); U.S. Const. amend. II (“A well regulated Militia,
    being necessary to the security of a free State, the right of the people to keep and bear Arms,
    shall not be infringed.”); U.S. Const. amend. V (“No person shall be held to answer for
    a capital, or otherwise infamous crime, unless on a presentment or indictment of a Grand
    Jury, except in cases arising in the land or naval forces, or in the Militia, when in actual
    service in time of War or public danger[.]”).
    6
    The federal militia statute, 
    10 U.S.C. § 246
    , provides:
    (a) The militia of the United States consists of all able-bodied males at least
    17 years of age and, except as provided in section 313 of title 32, under 45
    years of age who are, or who have made a declaration of intention to
    become, citizens of the United States and of female citizens of the United
    States who are members of the National Guard.
    (b) The classes of the militia are—
    (1) the organized militia, which consists of the National Guard and
    the Naval Militia; and
    (2) the unorganized militia, which consists of the members of the
    militia who are not members of the National Guard or the Naval
    Militia.

    officers, train militiamen, and govern the non-federalized militia; the States
    also share concurrent authority with Congress to provide for organizing,
    arming, and disciplining the militia—so long as the States’ rules aren’t
    inconsistent with Congress’s.7 Of course, Congress has the distinct
    constitutional power to “provide for the common Defence.” U.S. Const.
    art. I, § 8, cl. 1. But it cannot deploy that power in a manner that itself violates
    the Constitution or is otherwise coercive. See Pace v. Bogalusa City Sch. Bd.,
    
    403 F.3d 272
    , 279 (5th Cir. 2005).
    At the Founding, each of the above-italicized terms had a well
    understood meaning in the military domain. We (a) define each in the context
    of the Organizing Clause and then (b) analyze the Government’s
    enforcement measures.
    a.
    “As always, we start with the original public meaning of the
    Constitution’s text.” NetChoice, LLC v. Paxton, 
    49 F.4th 439
    , 452–53 (5th
    Cir. 2022). When the Organizing Clause was drafted, the words
    (i) “organize,” (ii) “arm,” (iii) “discipline,” and (iv) “govern” had well-
    understood meanings—especially in the military context.
    7
    As the Supreme Court said long ago in Houston v. Moore: “[T]he powers of
    legislation over [the militia] are concurrent in the general and State government. . . . [A]s
    State militia, the power of the State governments to legislate on the same subjects, having
    existed prior to the formation of the constitution, and not having been prohibited by that
    instrument, it remains with the States, subordinate nevertheless to the paramount law of
    the general government, operating upon the same subject.”

    , 16–17
    (1820) (Washington, J.); see also 
    id. at 50
     (Story, J.) (noting a point of agreement with the
    majority) (“It is almost too plain for argument, that the power here given to Congress over
    the militia; is of a limited nature, and confined to the objects specified in these clauses; and
    that in all other respects, and for all other purposes, the militia are subject to the control
    and government of the State authorities.”); United States v. Emerson,

    i.
    Organize: At the Founding, to “organize” generally meant “To
    construct so as that one part co-operates with another.” 2 Samuel
    Johnson, A Dictionary of the English Language 243 (6th ed.
    1785). And so in the military context, “organizing” included such things as
    “distribut[ing] [the whole] into suitable parts and appoint[ing] proper
    officers, that the whole may act as one body; as, to organize an army.”
    2 Noah Webster, An American Dictionary of the English
    Language 214 (1828); see also Records of the Federal Convention, reprinted
    in 3 The Founders’ Constitution 205, 206 (Philip B. Kurland &
    Ralph Lerner eds., 1987) (“Mr. King, by way of explanation, said that by
    organizing the Committee meant, proportioning the officers & men.”).
    Indeed, Congress in 1792 exercised its constitutional authority to “provide
    for organizing . . . the Militia” by passing a law requiring that “the militia of
    the respective states shall be arranged into divisions, brigades, regiments,
    battalions and companies.” Act of May 8, 1792, ch. 33, § 3, 
    1 Stat. 271
    , 272;
    cf. 2 Webster, supra, at 127 (defining “militia” as “the able bodied men
    organized into companies, regiments and brigades” (emphasis added)).
    Congress again leaned on the “organizing” power in the twentieth century
    when it reorganized the militia into the modern National Guard. See Perpich,
    
    496 U.S. at 342
    ; Frederick Bernays Wiener, The Militia Clause of the
    Constitution, 
    54 Harv. L. Rev. 181
     (1940).
    ii.
    Arm: “Arm” had much the same meaning at the Founding as it does
    today. Samuel Johnson’s 1785 dictionary defined “arm” as “To furnish with
    armour of defence, or weapons of offence.” 1 Johnson, supra, at 178;
    accord 1 Webster, supra, at 185 (“To furnish or equip with weapons of
    offense, or defense; as, to arm the militia.” (emphasis added)). Noah
    17
    Case: 22-40399        Document: 00516783843              Page: 18       Date Filed: 06/12/2023
    No. 22-40399
    Webster’s post-Founding 1828 dictionary defined “arming” similarly. 1
    Webster, supra, at 186 (“Equipping with arms; providing with the means
    of defense or attack.”). Accordingly, one might think that the Organizing
    Clause simply authorizes Congress to furnish weapons and other military
    equipment to the militia. It certainly does allow that; but because the
    Organizing Clause gives Congress the power to “provide for . . . arming,”
    U.S. Const. art. I, § 8, cl. 16, it also gives Congress authority to require
    that the militia be armed in other ways. As Rufus King explained at the
    Constitutional Convention, “arming” in this context “meant not only to
    provide for uniformity of arms, but included authority to regulate the modes
    of furnishing, either by the militia themselves, the State Governments, or the
    National Treasury.” Records of the Federal Convention, supra, at 206. Initially,
    Congress required militiamen to arm and equip themselves, at their own
    expense.8 Congress later appropriated “funding to support the [S]tates’
    National Guard, including the issue of arms, other military supplies, and
    other expenses.” Ass’n of Civilian Technicians, Inc. v. United States, 
    603 F.3d 989
    , 993 (D.C. Cir. 2010); see also

    “That every citizen so enrolled and notified, shall, within six months thereafter,
    provide himself with a good musket or firelock, a sufficient bayonet and belt, two spare
    flints, and a knapsack, a pouch with a box therein to contain not less than twenty-four
    cartridges, suited to the bore of his musket or firelock, each cartridge to contain a proper
    quantity of powder and ball; or with a good rifle, knapsack, shot-pouch and powder-horn,
    twenty balls suited to the bore of his rifle, and a quarter of a pound of powder; and shall
    appear, so armed, accoutred and provided, when called out to exercise, or into service,

    knapsack. That the commissioned officers shall severally be armed with a sword or hanger
    and espontoon, and that from and after five years from the passing of this act, all muskets
    for arming the militia as herein required, shall be of bores sufficient for balls of the
    eighteenth part of a pound.” Act of May 8, 1792, § 1, 1 Stat. at 271–72.

    iii.
    Govern: The Organizing Clause equips Congress with the power to
    “provide for . . . governing” the federalized militia. U.S. Const. art. I, § 8,
    cl. 16. And it reserves to the States the same power with respect to the non-
    federalized militia. See Holdiness, 
    808 F.2d at 421
     (“[T]he Governor remains
    in charge of the National Guard in each [S]tate except when the Guard is
    called into active federal service.”); 3 The Debates in the Several
    State Conventions on the Adoption of the Federal
    Constitution 424 (Jonathan Elliot ed., 1836) [hereinafter Elliot’s
    Debates] (James Madison, Virginia) (“The state governments are to
    govern the militia when not called forth for general national purposes; and
    Congress is to govern such part only as may be in the actual service of the
    Union. Nothing can be more certain and positive than this.”). Thomas
    Dyche and William Pardon’s 1740 dictionary offers a representative
    definition of “govern” as “to rule over, direct, keep in awe or subjection, to
    manage or take care of.” Thomas Dyche & William Pardon, A
    New General English Dictionary 358 (3d ed. 1740).9 That’s why
    we call the executive head of each State “Governor”—because he has the
    power to advance and enforce the laws. See 1 Webster, supra, at 840
    (defining “governor” as “One who is invested with supreme authority to
    administer or enforce the laws”).
    9
    Cf. 1 Johnson, supra, at 892 (defining “To govern” as “To rule as a chief
    magistrate” and “To regulate; to influence; to direct”); Nathan Bailey, An
    Universal Etymological English Dictionary 385 (4th ed. 1763) (defining
    “To govern” as “to rule, manage, look to, take care of”); 1 Webster, supra, at 840
    (defining “govern” as “To direct and control, as the actions or conduct of men, either by
    established laws or by arbitrary will; to regulate by authority; to keep within the limits
    prescribed by law or sovereign will. Thus in free states, men are governed by the constitution
    and laws; in despotic states, men are governed by the edicts or commands of a monarch”).

    Governing in the military context was understood (and still is)
    similarly. The Founding generation understood the “governing” power to
    encompass, inter alia, the power to command and control the troops10 as well
    as to enforce the relevant laws against them.11 They also understood the
    authority to enforce the law as naturally entailing the power to punish—or
    otherwise impose consequences upon—those subject to it.12 “Govern” is
    10
    E.g., 3 Story, supra, § 1208 (“The power to govern the militia, when in the
    actual service of the United States, is denied by no one to be an exclusive one. Indeed, from
    its very nature, it must be so construed; for the notion of distinct and independent orders
    from authorities wholly unconnected, would be utterly inconsistent with that unity of
    command and action, on which the success of all military operations must essentially
    depend.”); id. § 1210 (discussing the President’s authority to “govern[] and command[]”
    the federalized militia); U.S. Const. art. II, § 2, cl. 1 (the President is the “Commander
    in Chief” of the Army, Navy, and federalized militia (emphasis added)).
    11
    E.g., Moore, 18 U.S. (5 Wheat.) at 9 (“The power of governing the militia, is the
    power of subjecting it to the rules and articles of war.”); Sir Matthew Hale, The
    History of the Common Law of England 26–27 (Charles M. Gray ed., 1971)
    (“[F]or others who had not listed under the army had no color or reason to be bound by
    military constitutions applicable only to the army, whereof they were not parts, but they
    were to be ordered and governed according to the laws to which they were subject, though
    it were a time of war.”).
    12
    E.g., Charles Pinckney, Observations on the Plan of Government Submitted to the
    Federal Convention of May 28, 1787, reprinted in 3 The Founders’ Constitution,
    supra, at 207, 207–08 (arguing that “[t]he exclusive right of establishing regulations for the
    Government of the Militia of the United States, ought certainly to be ves[t]ed in the Federal
    Councils” because it is only then that the federal government would have “coercive
    Power” over the militia (emphasis added)); An Act for Establishing Rules and Articles for
    the Government of the Armies of the United States, ch. 20, 
    2 Stat. 359
     (1806) (listing the
    “articles for the government” of the military, including consequences and punishments for
    various offenses (emphasis added)); 1 William Blackstone, Commentaries

    law “establishe[d] . . . for their government,” including that, “if any officer and soldier shall
    excite, or join any mutiny, or, knowing of it, shall not give notice to the commanding officer;
    or shall desert, or list in any other regiment, or sleep upon his post, or leave it before he is
    relieved, or hold correspondence with a rebel or enemy, or strike or use violence to his
    superior officer, or shall disobey his lawful commands; such offender shall suffer such
    punishment as a court martial shall inflict, though it extend to death itself” (emphasis

    No. 22-40399
    used the same way earlier in the Constitution. Article I, Section 8, Clause 14
    assigns Congress the authority “[t]o make Rules for the Government and
    Regulation of the land and naval Forces.” And as the Supreme Court
    explained in Tarble’s Case, such power includes the ability to “define what
    shall constitute military offences, and prescribe their punishment.” 
    80 U.S. (13 Wall.) 397
    , 408 (1871).
    And so, because the Constitution only grants the United States
    governing authority over the militia after the militia has successfully been
    called forth “to execute the Laws of the Union, suppress Insurrections and
    repel Invasions,” U.S. Const. art. I, § 8, cls. 15, 16, it follows that “the
    Constitution gave the federal government no power to punish the militia in
    peacetime,” Benjamin Daus, Note, The Militia Clauses and the Original War
    Powers, 11 J. Nat’l Security L. & Pol’y 489, 508 (2021); see also, e.g.,
    Houston v. Moore, 
    18 U.S. (5 Wheat.) 1
    , 9 (1820) (“[I]t is a principle
    manifestly implied in the constitution, that the militia cannot be subject to
    martial law, except when in actual service, in time of war, rebellion, or
    invasion.”).
    iv.
    Discipline: Lastly, Congress can also “provide for . . . disciplining” the
    militia. U.S. Const. art. I, § 8, cl. 16. Founding-era dictionaries primarily
    associate “discipline” with education and instruction. For example, Samuel
    Johnson’s 1785 dictionary lists the first definition of “discipline” as
    “Education; instruction; the act of cultivating the mind; the act of forming
    the manners.” 1 Johnson, supra, at 601. Other dictionaries of that era are
    added)); see also Benjamin Daus, Note, The Militia Clauses and the Original War Powers, 11
    J. Nat’l Security L. & Pol’y 489, 508 (2021) (“In the Organizing Clause, . . .
    ‘govern’ refers to the power to punish.”).

    No. 22-40399
    of a piece.13 But those same dictionaries include other definitions associating
    “discipline” with punishment. Samuel Johnson’s fourth listed definition of
    “discipline,” for instance, is “A state of subjection.” 1 Johnson, supra, at
    602. And his sixth definition is “Punishment; chastisement; correction.”
    Ibid.14 So Congress’s “disciplining” power could mean either the ability to
    provide for the militia’s education and instruction or the authority to provide
    for their punishment—or both.
    In context, however, it appears clear that the Organizing Clause uses
    “discipline” to mean instruction and not punishment. U.S. Const. art. I,
    § 8, cl. 16. The end of the Organizing Clause reserves to the States “the
    Authority of training the Militia according to the discipline prescribed by
    Congress.” Ibid. (emphasis added). It makes little sense to train someone
    “according to the [punishments] prescribed by Congress.” Ibid. But it makes
    perfect sense to educate and teach the militia by training them “according to
    the [instructions] prescribed by Congress.” Ibid.; see also Daus, supra, at 508–
    09, 509 n.131 (arguing that in the Organizing Clause, the word “‘discipline’
    mean[s] skill or training” rather than “punishment” in large part because the
    “Constitution’s text itself link[s] training and discipline”).
    Moreover, if “discipline” included punishment, it would render the
    “governing” power largely superfluous. U.S. Const. art. I, § 8, cl. 16. As
    13
    See Dyche & Pardon, supra, at 229 (“education, instruction, teaching”);
    Bailey, supra, at 264 (“Education, Instruction, Management, strict Order”);
    1 Webster, supra, at 579 (“To instruct or educate; to inform the mind; to prepare by
    instructing in correct principles and habits; as, to discipline youth for a profession, or for
    future usefulness.”).
    14
    See also Dyche & Pardon, supra, at 229 (“also scourging or whipping, used
    by those who dwell in monasteries, by way of mortification”); Bailey, supra, at 264 (“to
    order or rule; to correct, scourge, or whip”); 1 Webster, supra, at 579 (“To correct; to
    chastise; to punish”).

    No. 22-40399
    explained above, the original public meaning of “governing” in the military
    context was the power to command troops and enforce laws against them,
    which included the ability to punish the troops and otherwise impose
    consequences for failure to obey the relevant rules of discipline. See supra
    notes 10–12 and accompanying text. That’s why the Supreme Court has said
    that “the rules of discipline” are those “by which the militia is to be
    governed.” Moore, 18 U.S. (5 Wheat.) at 14 (emphasis added); accord Orloff v.
    Willoughby, 
    345 U.S. 83
    , 94 (1953) (“The military constitutes a specialized
    community governed by a separate discipline from that of the civilian.”
    (emphasis added)). Therefore, while Congress can always “provide for . . .
    disciplining” the militia, it’s only when the militia is federalized that
    Congress can also “govern[]” them by punishing those who fail to conform
    to their prescribed discipline. U.S. Const. art. I, § 8, cl. 16 (only providing
    for “governing” the militia “employed in the Service of the United States”).
    This understanding of “discipline” tracks how the word was typically
    used in the military context at the Founding. The above-mentioned
    dictionaries, for example, primarily equate military discipline with teaching
    and instructing.15 As did the Founders and others during the Founding era.16
    15
    See 1 Webster, supra, at 579 (“military discipline, which includes instruction in
    manual exercise, evolutions and subordination”); ibid. (“To instruct and govern; to teach
    rules and practice, and accustom to order and subordination; as, to discipline troops or an
    army.”); 2 Webster, supra, at 126 (defining “militia” as “The body of soldiers in a state
    enrolled for discipline . . .”); 1 Johnson, supra, at 602 (“Military regulation.”); Dyche
    & Pardon, supra, at 229 (“the order or management observed in an army”).
    16
    Especially after the Revolutionary War, many Founders were worried about
    poorly trained soldiers, whom they described as “undisciplined.” See, e.g., George
    Washington, General Orders (Apr. 4, 1780) (“Commanding officers of Corps are
    immediately to put their new and undisciplined men in training.”); Letter from George
    Washington to Samuel Washington (Aug. 31, 1780) (“We are always without an Army—
    or have a raw and undisciplined one, engaged for so short a time that we are not fit either
    for the purposes of offence or defence, much less is it in our power to project schemes &

    execute plans which depend upon well disciplined and permanent Troops.”); Letter from
    John Adams to Colonel Hitchcock (Oct. 1, 1776) (“There is a Way, of introducing
    Discipline into the most irregular Army . . . . The first is . . . train[ing] your Regiments and
    Brigades to the manual Exercises and the Manoeuvres.”); Letter from Brigadier General
    George Weedon to George Washington (Dec. 1, 1777) (“Troops undisciplined [and] worn-
    out by service, deprived of every comfort which is necessary to restore health & vigor,
    cannot be supposed to support an attack against those who thro’ the Winter have been in
    comfortable quarters, constantly trained in Manœvreing & other exercises.”); 3 Elliot’s
    Debates, supra, at 51 (Patrick Henry, Virginia) (“Will your mace-bearer be a match for
    a disciplined regiment?”); The Federalist No. 29, at 143 (Alexander Hamilton)
    (George W. Carey & James McClellan eds., 2001) (“[I]t will be possible to have an
    excellent body of well trained militia, ready to take the field whenever the defence of the
    state shall require it. This will not only lessen the call for military establishments; but if
    circumstances should at any time oblige the government to form an army of any magnitude,
    that army can never be formidable to the liberties of the people, while there is a large body
    of citizens, little, if at all, inferior to them in discipline and the use of arms, who stand ready
    to defend their own rights, and those of their fellow citizens.”); Letter from Gouverneur
    Morris to Moss Kent (Jan. 12, 1815) (“But to rely on undisciplined, ill-officered men,
    though each were individually as brave as Caesar, to resist the well-directed impulse of
    veterans, is to act in defiance of reason and experience.”); Letter from W.H. Sumner to
    John Adams (May 3, 1823) (“[F]or what purpose did the convention maintain the right in
    congress, to prescribe [the militia’s] discipline? This right could be of no use, if the militia
    be not trained accordingly. . . . The value of our militia, as an example should be estimated
    by the superiority of its discipline. If what was said of the Massachusetts militia during the
    war, by one, who had seen that of the other states, was true, ‘that its spirit and drill was as
    much superior to that of most other parts of the country, as the value of its specie currency
    was above their unredeemed bills,’ our pride, as well as interest should be engaged in
    supporting its elevated standard.”).
    The Founders also sought to ensure that the militia be trained according to a
    uniform discipline so they could act in concert when federalized. See, e.g., Pinckney, supra,
    at 207 (“[A] uniformity in Discipline and Regulations should pervade the whole, otherwise,
    when the Militia of several States are required to act together, it will be difficult to combine
    their operations from the confusion a difference of Discipline and Military Habits will
    produce.”); The Federalist No. 29, at 140 (Alexander Hamilton) (“It requires no
    skill in the science of war to discern, that uniformity in the organization and discipline of
    the militia, would be attended with the most beneficial effects, whenever they were called
    into service for the public defence. It would enable them to discharge the duties of the camp
    and of the field with mutual intelligence and concert . . . an advantage of peculiar moment
    in the operations of an army; and it would fit them much sooner to acquire the degree of
    proficiency in military functions, which would be essential to their usefulness.”); 2
    Elliot’s Debates, supra, at 521 (James Wilson, Pennsylvania) (“[M]en without a

    So too did Congress. For example, Congress in 1792 passed “An Act
    more effectually to provide for the National Defence by establishing an
    Uniform Militia throughout the United States.” 
    1 Stat. 271
    . In § 7 of that Act,
    Congress adopted “Baron von Steuben’s ‘Rules of Discipline,’ which had
    originally been adopted by [the Continental] Congress in 1779.” Wiener,
    supra, at 214 n.188 (citing 13 Journals of the Continental
    Congress 384–85).17 Von Steuben’s disciplinary rules were a “150-plus-
    page manual regulat[ing] all manner of military operations,” from “the
    proper positioning of soldiers within a company and a regiment on the
    battlefield” to detailed “instructions for loading and firing rifles.” Saikrishna
    Bangalore Prakash, The Separation and Overlap of War and Military Powers,
    
    87 Tex. L. Rev. 299
    , 332 (2008); see also Joseph R. Riling, Baron
    von Steuben and His Regulations (1966) (including a complete
    facsimile of von Steuben’s Regulations). Here again, as elsewhere, the
    Founding generation understood militia “discipline” as the instructions and
    standards the United States wanted the militia to learn in state training so
    they would be uniformly prepared when “call[ed] forth.” U.S. Const. art.
    I, § 8, cl. 15.

    17
    See § 7, 1 Stat. at 273 (“And be it further enacted, That the rules of discipline,
    approved and established by Congress in their resolution of the twenty-ninth of March,
    [1779], shall be the rules of the discipline to be observed by the militia . . . . It shall be the
    duty of the commanding officer at every muster, whether by battalion, regiment, or single
    company, to cause the militia to be exercised and trained agreeably to the said rules of
    discipline.”).
    25
    Case: 22-40399       Document: 00516783843             Page: 26      Date Filed: 06/12/2023
    No. 22-40399
    set readiness requirements for non-federalized Guardsmen by dint of the
    “disciplining” power.18 And Governor Abbott stipulates that the erstwhile
    vaccine mandate was one such readiness requirement.
    The parties differ, however, on how to classify most of the
    enforcement measures. Recall that the Government has threatened five
    consequences against those who refused to get COVID injections while the
    mandate was in effect and who never sought an accommodation: (1) courts-
    martial; (2) discharge from the Guard; (3) prohibiting Guardsmen from
    participating in drills, training, and other duties; (4) withholding pay from
    individual Guardsmen; and (5) withholding funds from individual States.
    Governor Abbott stipulates that the fifth measure is constitutional. But he
    argues that the first four are impermissible “governing” of the non-
    federalized militia, and that the third measure additionally impedes upon the
    States’ “training” authority.
    We agree with the Governor. As explained above, the “governing”
    power encompasses the authority to punish the militia and otherwise enforce
    the relevant laws against them. See supra Part III.B.1.a.iii. On this
    understanding, both court-martialing and firing noncompliant Guardsmen
    are punishments. So are preventing those Guardsmen from training and
    withholding their pay. Accordingly, the Government’s enforcement orders
    unlawfully usurp Governor Abbott’s exclusive constitutional authority to
    “govern” the non-federalized Texas militia.
    18
    As the Government points out, “The Department of Defense and the military
    services have long required service members, including members of the National Guard, to
    meet stringent medical and physical fitness standards so that they remain ready to defend
    the nation.” These standards include height and weight requirements, fitness tests, and a
    range of immunizations.

    Founding-era history supports this understanding of the Organizing
    Clause. See Gamble v. United States, 
    139 S. Ct. 1960 (2019)
     (beginning with
    text before turning to history); Bruen, 
    142 S. Ct. 2111
     (same). We (a) begin
    with the background concerns that informed the Organizing and Calling
    Forth Clauses. Then we (b) discuss the Founders’ constitutional
    compromise, which gave the United States significant war powers but
    deprived the new national government the power to punish non-federalized
    militiamen.
    a.
    The Revolutionary War exposed many defects in the Articles of
    Confederation—chief among them its decentralized military structure. The
    Articles gave the federal government power to declare war and “make
    requisition from each state for its quota [of militiamen].” Articles of
    Confederation of 1781 art. IX, para. 5; see also 
    id.
     art. VI, para. 5.; 
    id.
     art.
    IX para. 1; The Federalist No. 22, at 105 (Alexander Hamilton)
    (George W. Carey & James McClellan eds., 2001) (“The power of raising
    armies [in the Articles] . . . is merely a power of making requisitions upon the
    states for quotas of men.”). And the States, in turn, were required to “always
    keep up a well regulated and disciplined militia, sufficiently armed and
    accoutred.” Articles of Confederation of 1781 art. VI, para. 4.
    “The problem of course was that the Articles of Confederation stopped
    midstream. Congress was empowered to wage war but was dependent on the
    cooperation of the [S]tates to do so.” Jason Mazzone, The Security
    Constitution, 
    53 UCLA L. Rev. 29
    , 76 (2005). That’s because there was
    “no mechanism to force the [S]tates to comply.” 
    Ibid.
    This system proved costly and cumbersome. For one, it produced a
    collective action problem: “The States near the seat of war, influenced by
    27
    Case: 22-40399        Document: 00516783843               Page: 28        Date Filed: 06/12/2023
    No. 22-40399
    motives of self-preservation, made efforts to furnish their quotas, which even
    exceeded their abilities; while those at a distance from danger were, for the
    most part, as remiss as the others were diligent, in their exertions.”
    Federalist No. 22, at 106 (Alexander Hamilton). This led to “scanty
    levies of men” in “the most critical emergencies.” 
    Ibid.
     Relatedly, because
    there was little to no national coordination of the militia’s preparation, the
    Revolutionary War exposed a concomitant “lack of uniformity in [the
    militia’s] organization, equipment and training.” Francis X. Conway, A
    State’s Power of Defense Under the Constitution, 
    11 Fordham L. Rev. 169
    ,
    174 (1942).19 As early as September of 1776, George Washington expressed
    his frustrations about the militia to John Hancock: “To place any dependance
    upon Militia, is, assuredly, resting upon a broken staff.” Letter from George
    Washington to John Hancock (Sept. 25, 1776). Although Washington’s
    statement proved hyperbolic—the militia had its share of triumphs during
    the Revolution20—the sentiment rang true: the new Constitution needed to
    give the United States greater power to provide for national security.
    19
    At the Constitutional Convention, for example, Charles Pinckney “mentioned a
    case during the war in which a dissimilarity in the militia of different States had produced
    the most serious mischiefs.” Records of the Federal Convention, supra, at 205. Others
    including George Mason, James Madison, and Alexander Hamilton expressed similar
    sentiments about military uniformity and discipline. See id. at 205–06; The Federalist
    No. 29, at 140 (Alexander Hamilton) (“This desirable uniformity can only be
    accomplished, by confiding the regulation of the militia to the direction of the national
    authority.”); see also supra note 16.
    20
    See Daus, supra, at 501 (“During the war, the militia won a mixed record, and
    those frustrated with the institution contemplated its reform, not its abolition. For each
    humiliating rout[] like the one at Guilford Courthouse came a modest triumph against the
    Cherokee, loyalist militias, or British Regulars in guerilla campaigns. A remark by Lord
    Cornwallis captured the record’s ambivalence: ‘I will not say much in praise of the militia
    . . . but the list of British officers and soldiers killed and wounded by them . . . proves but
    too fatally they are not wholly contemptible.’”).

    On the other hand, “[a]mong the ratifying generation, support for a
    [stronger] national military coexisted with widespread fears of a standing
    army.” Mazzone, supra, at 65; see also United States v. Miller, 
    307 U.S. 174
    ,
    179 (1939) (“The sentiment of the time strongly disfavored standing armies;
    the common view was that adequate defense of country and laws could be
    secured through the Militia-civilians primarily, soldiers on occasion.”);
    District of Columbia v. Heller, 
    554 U.S. 570
    , 597–99 (2008). Informed in no
    small part by their experiences with British troops on American soil, see
    Declaration of Independence paras. 13, 14, 16 (U.S. 1776), the
    Founding generation worried that professional soldiers would imperil the
    promises of a free government, see Akhil R. Amar, The Bill of
    Rights: Creation and Reconstruction 53–56 (1998). That’s
    because professional soldiers—unlike the citizen-populated militia—were
    “removed from the freedoms enjoyed by the republican political community
    that they were defending.” Robert Leider, Federalism and the Military Power
    of the United States, 
    73 Vand. L. Rev. 989
    , 996 (2020); see also 1 William
    Blackstone, Commentaries *414–17. The Founding generation
    thought this weakened the soldiers’ ties to the rest of society and rendered
    them vulnerable to manipulation by tyrants. Thus, as Samuel Adams wrote:
    A standing Army . . . is always dangerous to the Liberties of the
    People. Soldiers are apt to consider themselves as a Body
    distinct from the rest of the Citizens. They have their Arms
    always in their hands. Their Rules and their Discipline is
    severe. They soon become attachd to their officers and disposd
    to yield implicit Obedience to their Commands. Such a Power
    should be watchd with a jealous Eye. . . . Men who have been
    long subject to military Laws and inured to military Customs
    and Habits, may lose the Spirit and Feeling of Citizens. . . .
    [But] [t]he Militia is composd of free Citizens. There is
    therefore no Danger of their making use of their Power to the

    destruction of their own Rights, or suffering others to invade
    them.
    Letter from Samuel Adams to James Warren (Jan. 7, 1776). Federalists and
    Anti-Federalists alike expressed the same concerns.21 As did generations of
    their forefathers “[t]hroughout English history.” Conway, supra, at 174.
    The Federalists and Anti-Federalists also agreed on this: They
    “prized and cherished” the militia as “the palladium of liberty.” Ibid.
    Inspired by the storied militia system of Mother England, every colony (save
    for Pennsylvania) organized a militia as early as the seventeenth century. See
    Mazzone, supra, at 70–71 (“Every able-bodied, white male was required to
    arm himself, enroll in the local unit, participate in training exercises, and go
    to fight when called.”). The Founders continued to believe that such a large
    group of armed and trained men intensely loyal to their States and localities
    would “enable the people to resist and triumph over” sudden “foreign

    See, e.g., 3 Elliot’s Debates, supra, at 381 (James Madison, Virginia) (“[A]
    standing army is one of the greatest mischiefs that can possibly happen.”); id. at 401

    member in the federal Convention, who did not feel indignation at such an institution.”);

    238–39 & nn.44–45 (collecting statements from various Anti-
    Federalists expressing “fear[] that the federal government’s standing army could be used
    to tyrannize and oppress the American people”); 3 Elliot’s Debates, supra, at 379
    (George Mason, Virginia) (“There are various ways of destroying the militia. A standing
    army may be perpetually established in their stead. I abominate and detest the idea of a
    government, where there is a standing army.”); John DeWitt, To the Free Citizens of the
    Commonwealth of Massachusetts (1787), reprinted in 4 The Complete Anti-
    Federalist 34, 37–38 (Herbert J. Storing ed., 1981) (“[S]tanding armies are a solecism
    in any government . . . . [N]o nation ever supported them, that did not resort to, rely on,
    and finally become a prey to them. . . . They are brought up to obedience and unconditional
    submission.—With arms in their hands, they are taught to feel the weight of rigid
    discipline:—They are excluded from the enjoyments which liberty gives to its votaries,
    they, in consequence, hate and envy the rest of the community in which they are placed,
    and indulge a malignant pleasure in destroying those privileges to which they never can be
    admitted.”).

    (Paul L. Ford ed., 1888) (“The supreme power in America cannot enforce
    unjust laws by the sword; because the whole body of the people are armed,
    and constitute a force superior to any band of regular troops that can be, on
    any pretence, raised in the United States.”).
    But the militia was more than just a check against tyranny. The
    Founding generation also considered it an essential civic institution and a
    source of pride. Where the contemporary military is national, hierarchical,
    and professional, the early-American militia was local, democratic, and
    unapologetically amateur. In the minds of the Founding generation, the
    militia thus sparked notions of civic duty, self-reliance, and republican virtue.

    98. Even those most comfortable with standing armies and professional
    soldiers (like Hamilton and Washington22) paid their respects to the militia.23
    The Constitution thus must be understood in this tripartite historical
    context. (1) The Founding generation understood the need for a strong
    national defense. (2) Yet the Founders loathed and feared standing armies.
    The bridge between those two propositions? (3) They cherished and trusted
    the militia, which was first and foremost a state prerogative—unless and until
    federalized by the general government.

    See, e.g., The Federalist No. 25, at 125 (Alexander Hamilton) (“The
    steady operations of war against a regular and disciplined army, can only be successfully
    conducted by a force of the same kind. . . . War, like most other things, is a science to be
    acquired and perfected by diligence, by perseverance, by time, and by practice.”);

    (“Regular Troops alone are equal to the exigencies of modern war, as well for defence as
    offence, and whenever a substitute is attempted it must prove illusory and ruinous. No
    Militia will ever acquire the habits necessary to resist a regular force. . . . The firmness
    requisite for the real business of fighting is only to be attained by a constant course of
    discipline and service.”).

    people, while there is a large body of citizens, little, if at all, inferior to them in discipline
    and the use of arms, who stand ready to defend their own rights and those of their fellow-
    citizens. This appears to me the only substitute that can be devised for a standing army;
    and the best possible security against it, if it should exist.”); George Washington,

    Militia, we might not only shew the propriety of the measure from our peculiar local
    situation, but we might have recourse to the Histories of Greece and Rome in their most
    virtuous and Patrioic ages to demonstrate the Utility of such Establishments.”).

    The Constitution reflects all three propositions. To ensure the United
    States can adequately defend itself, the Constitution assigns Congress the
    power to “raise and support” an Army and Navy. U.S. Const. art. I, § 8,
    cl. 12. But to force Congress to “periodically debat[e] whether to continue
    funding a standing army,” Leider, supra, at 1000, that power is subject to the
    limitation that “no Appropriation of Money to that Use shall be for a longer
    Term than two Years,” U.S. Const. art. I, § 8, cl. 12.
    The Constitution also preserves the militia as another check on the
    standing Army. But unlike the Articles of Confederation, the Constitution
    more substantially bifurcates authority over the militia between the state and
    federal governments. Primary control resides with the States, but the United
    States can use and control the militia in certain circumstances. To dampen
    the need for a standing army, Congress can provide for “calling forth” the
    militia into federal service and for “governing” such part of them in federal
    service. Id. cls. 15–16. The “calling forth” power, however, is in turn limited
    to three purposes: “execut[ing] the Laws of the Union, suppress[ing]
    insurrections[,] and repel[ling] invasions.” Id. cl. 15.
    What about the lack of training and uniformity that plagued the militia
    during the Revolution? The Constitution addresses this by authorizing
    Congress to provide uniform standards for the organizing, arming, and
    disciplining of the militia. Id. cl. 16. But to keep the militia tethered to its state
    and local roots and to insulate it from national capture, the States retained
    the right to conduct the militia’s training, appoint officers, and govern the
    non-federalized militia. Ibid.24 Such state control—alongside other
    24
    See, e.g., 3 Story, supra, § 1202 (“The appointment of the officers of the militia
    was exclusively in the states; and how could it be presumed, that such men would ever
    consent to the destruction of the rights or privileges of their fellow-citizens. The power to

    constitutional assurances like the Second Amendment, see Heller, 
    554 U.S. at
    599—was intended to make the militia a potent counterweight to any abuses
    of national military power.25
    Here, as in so many areas of constitutional interpretation, the
    Federalist–Anti-Federalist debates are illuminating. The Anti-Federalists
    worried that the federal government would arrogate to itself too much power
    discipline and train the militia, except when in the actual service of the United States, was
    also exclusively vested in the states; and under such circumstances, it was secure against
    any serious abuses.”); The Federalist No. 29, at 143 (Alexander Hamilton) (“What
    shadow of danger can there be from men, who are daily mingling with the rest of their
    countrymen; and who participate with them in the same feelings, sentiments, habits and
    interests? What reasonable cause of apprehension can be inferred from a power in the union
    to prescribe regulations for the militia, and to command its services when necessary; while
    the particular states are to have the sole and exclusive appointment of the officers? If it were
    possible seriously to indulge a jealousy of the militia, upon any conceivable establishment
    under the federal government, the circumstance of the officers being in the appointment of
    the states, ought at once to extinguish it. There can be no doubt, that this circumstance will
    always secure to them a preponderating influence over the militia.”); A Native of Virginia,
    Observations Upon the Proposed Plan of Federal Government (1788), reprinted in 1 The
    Writings of James Monroe, 349, 371–72 (Stanislaus Murray Hamilton ed., 1898)
    (“How can the command of Congress over the militia be either absolute or unqualified,
    when its officers are appointed by the States, and consequently can by no possibility become
    its creatures? They will generally be men of property and probity: And can any one for a
    moment suppose that such men will ever be so lost to a sense of liberty, the rights of their
    country, and their own dignity, as to become the instruments of arbitrary measures?
    Whenever that shall be the case, we may in vain contend for forms of government; the spirit
    of liberty will have taken its flight from America, and nothing but an arbitrary government
    will be fit for such a people, however accurately defined the powers of her Constitution may
    be.”).

    “In fact two of the strongest champions of a regular army, Hamilton and
    Madison, went so far as to make persuasive pleas in The Federalist for the grant of power to
    Congress to raise a standing army on the premise that the militia of the several states would
    be adequate protection against any encroachment by the Federal Government through its
    use of a regular army.” Conway, supra, at 174–75; see also The Federalist No. 29

    over the States’ militias. The Federalists insisted that would never happen
    and that non-federalized militias would remain the States’ domain.
    Let’s start with the Anti-Federalists’ concerns. At the constitutional
    convention, for example, the great Anti-Federalist Elbridge Gerry exclaimed
    that if too much control over the militia was taken away from the States, the
    Constitution would “have as black a mark as was set on Cain.” Records of the
    Federal Convention, supra, at 206; see also Luther Martin’s Letter on the
    Federal Convention of 1787, reprinted in 1 Elliot’s Debates, supra, at
    344, 372 (“[If too much] power over the militia should be taken away from
    the [S]tates, and also given to the general government, it ought to be
    considered as the last coup de grace to the State governments.”). The Anti-
    Federalists also worried that if the United States was given too much control
    over the militia, it would attempt to subvert the institution by, inter alia,
    “making militia service so unpleasant that the people would demand a
    standing army.” United States v. Emerson, 
    270 F.3d 203
    , 238 (2001); see also
    
    id.
     at 237–39. And the Anti-Federalists feared that the United States might
    fine, court-martial, and otherwise punish non-federalized militiamen as a way
    “to cow the militia, destroy it, or convert it into a tool of oppression.” Daus,
    supra, at 509.26
    26
    See, e.g., 3 Elliot’s Debates, supra, at 400 (Virginia Ratifying Convention)
    (“[I]t is feared that the militia are to be subjected to martial law when not in service.”); id.
    at 402 (George Mason, Virginia) (“[A]fter having read the clause which gives Congress
    power to provide for arming, organizing, and disciplining the militia, and governing those
    in actual service of the Union, [Mason] declared it as his firm belief, that it included the
    power of annexing punishments . . . . If so, he asked if Congress could not inflict the most
    ignominious punishments on the most worthy citizens of the community. . . . It might be
    thought a strained construction, but it was no more than Congress might put upon it. He
    thought such severities might be exercised on the militia as would make them wish the use
    of the militia to be utterly abolished, and assent to the establishment of a standing army.”);

    In response, the Federalists assured the Anti-Federalists time and
    again that the Organizing Clause would only authorize punishment after the
    militia had been “called forth”—and the “governing” power had been
    unlocked. At the Virginia Ratifying Convention, for example, Anti-Federalist
    George Mason worried that the Organizing Clause countenanced “the power
    of annexing punishments” against the militia. 3 Elliot’s Debates,
    supra, at 402 (he did, however, admit this was a “strained construction” of
    that Clause). Henry Lee then quickly and forcefully retorted that Mason was
    “mistaken.” Id. at 407. Lee proclaimed: “Suffice it to say, [the Organizing
    Clause] does not include the infliction of punishments. The militia will be
    subject to the common regulations of war when in actual service; but not in
    time of peace.” Ibid. A chorus of other Federalists made similar arguments.27
    at 145, 164 (“The absolute unqualified command that Congress have over the militia may
    be made instrumental to the destruction of all liberty . . . . As militia they may be subjected
    to fines to any amount, levied in a military manner; they may be subjected to corporal
    punishments of the most disgraceful and humiliating kind, and to death itself, by the
    sentence of a court martial.”); Letter from George Mason to Thomas Jefferson (May 26,
    1788) (“There are many other things very objectionable in the proposed new Constitution;
    particularly the almost unlimited Authority over the Militia of the several States; whereby,
    under Colour of regulating they may disarm, or render useless the Militia, the more easily
    to govern by a standing Army; or they may harrass the Militia, by such rigid Regulations

    powers only amount to this—that they can only call them forth in these three cases, and
    that they can only govern such part of them as may be in the actual service of the United

    can bear such a construction. Congress has only the power of arming and disciplining them.
    The states have the appointment of the officers, and the authority of training the militia,
    according to the discipline prescribed by Congress. When called into the actual service of

    Soon after the Constitution was ratified, Congress provided
    punishments for those in the Army and the federalized militia only.28
    (Tellingly, many of those punishments mirror those the Government has
    here threatened against Texas’s Guardsmen—including courts martial,
    discharge, and withholding pay.) Although Congress in 1792 “did pass a
    statute that purported to establish ‘an Uniform Militia throughout the
    United States,’ . . . [it] was virtually ignored for more than a century.”

    ; see supra Part III.B.1.a.iv (discussing Congress’s
    adoption of Baron von Steuben’s “Rules of Discipline”). And the
    Government hasn’t cited a single example of the United States punishing
    such delinquency during those hundred-odd years.
    In fact, the only time the Founding-era Congress provided any
    punishments for non-federalized militiamen was when they refused the
    President’s call to serve. See Act of May 2, 1792, ch. 28,

    . But as the
    Revolutionary War demonstrated, the young Nation’s defense depended
    equally upon the militia’s discipline and its willingness to serve when called
    by the President. See supra Part III.B.2.a; see also supra note 16. Yet the
    ratifying generation only punished the latter. Why? Because the Constitution
    only gave them authority to do the latter.29
    Thus, the Constitution’s text, history, and tradition instruct that
    States retain exclusive authority to punish militiamen—unless and until
    called into national service. If and when the militia is called into federal
    service, the President can punish either the refusal to heed his call or the
    refusal to meet his standards. But that power exists only when the militia is
    called into national service. That’s why President Biden is “Commander in
    Chief . . . of the Militia of the several States” only “when called into the actual
    Service of the United States.” U.S. Const. art II, § 2 (emphasis added). And
    it’s also why Governor Abbott remains “Commander-in-Chief of the military
    forces of the State” at all other times. Tex. Const. art IV, § 7; see

    suitable penalties to disobedience of their orders, and direct the manner, in which the

    The Constitution forbids President Biden from treating the non-
    federalized militia just like the Army. One of the Constitution’s most
    foundational compromises reserved substantial authority over the militia to
    the States. As demonstrated at length above, the plain meaning of the
    Organizing Clause as well as pre-ratification and post-ratification history all
    point in the same direction: Governor Abbott retains exclusive power to
    punish his non-federalized Guardsmen and otherwise govern them.
    Governor Abbott is thus likely to succeed on his claim that the Government’s
    challenged enforcement measures are unconstitutional.
    C.
    Against the Constitution’s text, history, and tradition, President
    Biden offers four counterarguments. None is persuasive.
    1.
    The Government claims that the Founding-era history discussed
    above isn’t relevant because the modern National Guard didn’t exist at the
    Founding. True, but irrelevant. “The National Guard is the modern Militia
    reserved to the States by Art. I, § 8, cl. 15, 16 of the Constitution.” Maryland,
    
    381 U.S. at 46
     (emphasis added). And everyone agrees that the modern
    militia, to the same degree as the militia of the late 1700s, is subject to Article
    I, Section 8, Clause 16 of the United States Constitution. That Clause
    couldn’t be clearer: when Congress exercises its “organizing” power (as it
    did when it created the modern National Guard), it doesn’t also unlock some
    new “governing” power. U.S. Const. art. I, § 8, cl. 16; see Moore, 18 U.S.
    (5 Wheat.) at 48 (Story, J.) (“[W]e are not at liberty to add one jot of power
    to the national government beyond what the people have granted by the
    constitution.”).

    No. 22-40399
    Moreover, the above history does shed light on this dispute. The
    Founders created a vertical separation of powers over the militia precisely to
    prevent the federal government from treating the militia just like the Army.
    See supra Part III.B.2. Today—just as in 1789—the Organizing Clause
    ensures that the militia remains under state governance unless and until it is
    properly federalized. And it’s hard to imagine a more obvious exercise of the
    “governing” power than punishing someone for disobedience.
    2.
    The Government next contends that its threatened enforcement
    measures are not “punishments,” but instead are mere “consequences”
    emanating from its “disciplining” power. That’s so, it says, because
    “disciplining” “naturally includes the ability to impose consequences for
    non-compliance with the rules prescribed.” Red Br. 31. Or as the
    Government put it elsewhere, “[a] necessary corollary to the ability to set
    readiness standards is the ability to enforce readiness standards.” Id. at 23.
    That reasoning is flawed for a host of reasons. We’ll highlight three.
    First, as a textual matter, the Government’s capacious understanding
    of the “disciplining” power contravenes the original public meaning of
    “discipline”—the skills and standards the United States wanted the militia
    to learn in state training. See supra Part III.B.1.a.iv. It also robs the
    “governing” power of its original meaning by rendering it largely
    superfluous. See supra Part III.B.1.a.iii. Worse yet, this reading rips the
    otherwise cohesive constitutional fabric by giving the term “govern”
    radically distinct meanings just two sentences apart. Ibid. Compare U.S.
    Const. art. I, § 8, cl. 14, with id. cl. 16. See also Akhil R. Amar,
    Intratextualism,

     (1999).
    Second, and crucially, the Government obviously does not consider
    the COVID vaccine mandate a “readiness standard” because the Government
    41
    Case: 22-40399      Document: 00516783843            Page: 42     Date Filed: 06/12/2023
    No. 22-40399
    repealed the mandate. Indeed, the Government hasn’t threatened any
    “consequences” against (A) unvaccinated Guardsmen hired after the
    mandate’s repeal. But the Government has threatened to impose
    “consequences” against (B) those Guardsmen who didn’t get injections
    while the mandate was in effect. How could the mandate constitute a
    “readiness requirement” if Guardsmen A can freely ignore it, but
    Guardsmen B can’t? Thus—contrary to the Government’s frequent pre-
    repeal statements—the mandate has nothing to do with “ensur[ing] that
    National Guard members are ready to integrate into U.S. military operations
    and to serve the nation on short notice” because members of that military
    now have diametrically different vaccination statuses. Nor are the
    enforcement measures mere “consequences” in furtherance of military
    readiness. Instead, they’re punishments for disobedience—pure and
    simple. See Leo Shane III, Troops Who Refused COVID Vaccines Still Could
    Face Punishment, Military Times (Feb. 28, 2023), https://www.militar
    ytimes.com/news/coronavirus/2023/02/28/troops-who-refused-covid-
    vaccines-still-could-face-punishment/ (“[T]hose who refused [vaccination]
    in the past could still be booted for ‘disobeying a lawful order’ . . . . ‘It’s very
    important that our service members follow orders when they are lawful, and
    there are thousands that did not,’ Gilbert Cisneros Jr., Under Secretary of
    Defense for Personnel, told members of the House Armed Services
    Committee.”). The only thing that differentiates Guardsmen A and
    Guardsmen B is obedience—not readiness.
    Finally, as a structural matter, even if the power to “provide for . . .
    disciplining” the militia included the ability to punish disobedience, the
    Constitution commands that the States alone can mete out that discipline to
    non-federalized Guardsmen. And States do that, of course, by (1) “training
    the Militia according to the discipline prescribed by Congress” and
    (2) otherwise “governing” them. U.S. Const. art. I, § 8, cl. 16; see also
    42
    Case: 22-40399     Document: 00516783843           Page: 43    Date Filed: 06/12/2023
    No. 22-40399
    supra Parts III.B.1.a.iii–iv. So call them “punishments” or call them
    “consequences,” the Constitution is clear that only the States can enforce
    the discipline Congress enacts. If President Biden wants to do it himself, he
    must first federalize the Texas Guard. But if President Biden is unwilling or
    unable to do so, he cannot punish Guardsmen B as if he’d federalized the
    Guard. If the Constitution makes anything clear, it’s that federalization
    matters.
    To all this, the Government defends its capacious reading of
    “discipline” by arguing that “governing” would still have some meaning
    under its interpretation: “When the federal government is ‘governing’ the
    militia, the National Guard is under the exclusive control of the federal
    government in ways that the non-federalized National Guard is not.” Red Br.
    33. But even if the Government’s interpretation gives “governing” some
    meaning, it’s still unconstitutional if it doesn’t give “governing” the right
    meaning. Regardless, if the Government could simply bypass the States’
    Governors and enforce any requirement it liked directly against the States’
    Guardsmen, it’s unclear what new power the Government unlocks once it
    federalizes the Guard. U.S. Const. art. I, § 8, cl. 16 (granting Congress
    the power “[t]o provide for . . . governing such Part of [the militia] as may be
    employed in the Service of the United States”). Nor is it clear why the
    Founders took such care to separate “governing” from “disciplining” in this
    context and reserve the former to the States by default. Cf. U.S. Const.
    art. I, § 8, cl. 14 (assigning the governing power with no mention of
    “disciplining”); see also supra Part III.B.2. “This strange treatment of the
    constitutional text cannot be justified.” Fulton v. City of Philadelphia, 
    141 S. Ct. 1868
    , 1894 (2021) (Alito, J., concurring); see also Wright v. United States,
    
    302 U.S. 583
    , 588 (1938) (“To disregard such a deliberate choice of words
    and their natural meaning would be a departure from the first principle of

    Case: 22-40399       Document: 00516783843          Page: 44    Date Filed: 06/12/2023
    No. 22-40399
    constitutional interpretation”—that “every word must have its due force,
    and appropriate meaning.” (quotation omitted)).
    3.
    The Government alternatively frames its threatened punishments as
    “merely the enforcement of conditions on the receipt of federal funds.” The
    district court did too: “looking past labels, the consequences at issue are only
    an inability to receive federal pay, benefits, and recognition for militia service
    not compliant with federal regulations.” But it is an elementary proposition
    of constitutional law that “conditions attached to Spending Clause legislation
    are valid only if they are . . . not in violation of an independent constitutional
    provision.” Miller v. Tex. Tech Univ. Health Scis. Ctr., 
    421 F.3d 342
    , 348 n.15
    (5th Cir. 2005) (en banc) (citing South Dakota v. Dole, 
    483 U.S. 203
    , 207–08
    (1987)). Here, the Organizing Clause imposes an independent constitutional
    bar against governing the non-federalized militia. If the Government is
    unwilling or unable to federalize the noncompliant Guardsmen, the most the
    Government could do is withhold money from the State’s Guard. See 
    32 U.S.C. § 108
    . Governor Abbott could then either make up that funding from
    the State’s fisc; or he could decide where the consequences of that financial
    cut would fall.
    The Government protests that Congress gave it the statutory
    authority to do more than simply withhold funding from the States.
    Specifically, the Government points to 
    32 U.S.C. §§ 322
    –24 to justify its
    authority to withdraw Guardsmen’s federal recognition and discharge them;
    to §§ 501–02 for its authority to prohibit Guardsmen from participating in
    drills, training, and other duties; and to § 108 for its authority to withhold pay
    from individual Guardsmen. It’s unclear that the Government has the best
    reading of these statutes. But in any event, this mode of reasoning is deficient
    for the same reason as the last: Regardless of whether the Government’s
    44
    Case: 22-40399      Document: 00516783843            Page: 45    Date Filed: 06/12/2023
    No. 22-40399
    reading of these statutes is correct, the Constitution forbids President Biden
    from bypassing the States, stepping into Governor Abbott’s shoes, and
    directly governing Texas’s non-federalized militiamen.
    4.
    Finally, the court below based its decision in large part on its
    understanding that the Government has not threatened to court martial any
    non-federalized Guardsmen. As the district court explained, “the
    vaccination requirement at issue is enforced only through a denial of federal
    pay, federal benefits, and federal recognition that enables those federal pay
    and benefits.” That was error. In its opposition to Governor Abbott’s
    preliminary injunction motion, the Government attached a declaration of
    Colonel Mulcahy, who summarized the “various means for the federal
    government to ensure that state National Guards comply with federal
    military regulations when they are performing federally authorized training
    and missions in a Title 32 status.” Among other things, Colonel Mulcahy
    listed “courts-martial of National Guard service members who are not in
    Federal service” and cited the statutory authority for courts-martial, 
    32 U.S.C. §§ 326
    –27. Relying on this declaration, the Government said in no
    uncertain terms that “failure to comply with federal regulations can lead to
    individual adverse actions, including formal written reprimands up to court
    martial.” If this is not a threat, it’s unclear what else it could be.
    As a backup argument, the Government qualifies Colonel Mulcahy’s
    declaration by explaining that “[a]lthough Congress [in 
    32 U.S.C. §§ 326
    –
    27] has provided the means for court-martial of non-federalized National
    Guard members, any consequences imposed under those statutory
    provisions would be imposed by the state through its own court-martial
    regime and as provided by state law.” Thus, the Government says, there’s
    “no risk” that the non-federalized Guardsmen “would be punished by the
    45
    Case: 22-40399     Document: 00516783843              Page: 46   Date Filed: 06/12/2023
    No. 22-40399
    federal government.” That’s also incorrect. Sections 326 and 327 make clear
    that while the ultimate punishment would be “as provided by the laws of the
    respective States,” 
    32 U.S.C. § 326
    , the federal government would be the
    one convening the courts-martial imposing the punishments, see 
    id.
     § 327(b)
    (“In the National Guard not in Federal service . . . general courts-martial may
    be convened by the President.”). The Mulcahy declaration reaffirms this
    reading by listing courts-martial as one of the “means for the federal
    government to ensure that state National Guards comply with federal military
    regulations.”
    IV.
    In addition to likelihood of success on the merits, Governor Abbott
    must also demonstrate “that he is likely to suffer irreparable harm in the
    absence of preliminary relief, that the balance of equities tips in his favor, and
    that an injunction is in the public interest.” Winter, 
    555 U.S. at 20
    . Because
    the district court only considered the likelihood-of-success prong, we remand
    so the district court can consider the other three in the first instance. E.g.,
    Sambrano v. United Airlines, Inc., 
    2022 WL 486610
     (5th Cir. 2022) (per
    curiam) (remanding for consideration of the not-yet-evaluated preliminary
    injunction factors).
    We do, however, note that the situation is materially different now
    than it was when the district court first considered Governor Abbott’s
    preliminary injunction motion. That’s because the Government repealed the
    vaccine mandate whilst still threatening punishment for past disobedience.
    That obviously changes the nature of all three remaining preliminary-
    injunction factors.
    *        *         *
    The Government conceded that its erstwhile vaccine mandate is
    unnecessary to military readiness by repealing it. The question, therefore, is
    46
    Case: 22-40399     Document: 00516783843           Page: 47    Date Filed: 06/12/2023
    No. 22-40399
    whether the President can punish non-federalized Guardsmen in Texas who
    refused to get COVID injections before the President and Congress deemed
    such injections unnecessary. For the reasons given above, we hold that the
    Constitution’s text, history, and tradition foreclose the President’s efforts to
    impose such punishments.
    We VACATE the district court’s order denying Governor Abbott’s
    motion for a preliminary injunction and REMAND for further proceedings
    consistent with this opinion.
