Over a year ago, the President of the United States proclaimed
Venezuelan citizens in this country “immediate[ly]” removable “[a]lien
[e]nemies” if they were members of a certain gang and “not actually
naturalized or lawful permanent residents.” That Proclamation has
generated litigation around the country in federal courts at all levels. Here,
three “Venezuelan national[s]” sued the President and other
federal-government defendants, on petitioners’ own behalf and that of a
putative class, claiming that the Proclamation violates, as relevant here, the
Alien Enemies Act of 1798 and due-process guarantees. Petitioners
unsuccessfully sought preliminary injunctive relief against summary removal
under the AEA in the district court and our court before the Supreme Court
returned the case to us.
Now, on remand, the Supreme Court has specifically asked us to
answer two questions: (1) whether the named petitioners’ claims that the
President violated the AEA warrant a preliminary injunction and (2) whether
the President’s Proclamation violates due process as to a putative class. But

No. 25-10534
after oral argument before the en banc court, we learned that the government
has removed all three named petitioners under the Immigration and
Nationality Act—that is, not the AEA. This development is unobjectionable:
The Supreme Court expressly said that the government could remove the
named petitioners and putative class under other laws. And petitioners point
out no infirmities in their removal.
We DISMISS the appeal for lack of jurisdiction.
I
A
On March 14, 2025, the President issued a proclamation invoking the
AEA against “all” citizens of Venezuela fourteen years of age or older within
the United States who “are not actually naturalized or lawful permanent
residents of the United States” and “are members of” Tren de Aragua.
Invocation of the Alien Enemies Act Regarding the Invasion of the United States
by Tren de Aragua, 90 Fed. Reg. 13033, 13034 (Mar. 14, 2025). Tren de
Aragua, a designated foreign terrorist organization, id. at 13033; Foreign
Terrorist Organizations, U.S. Dep’t of State, https://www.state.gov/foreign-
terrorist-organizations (last visited Aug. 11, 2026), began as a Venezuelan
prison gang and has since “bec[o]me Venezuela’s most powerful criminal
enterprise,” a “feared criminal organization focused on sex trafficking,
human smuggling[,] and the drug trade,” Luis Ferré-Sadurní & Chelsia Rose
Marcius, Venezuelan Gang’s Path to U.S. Stokes Fear, Crime and Border
Politics, N.Y. Times (Sep. 22, 2024), https://perma.cc/QM86-NGAG.
According to the Proclamation, Venezuelan authorities have gradually
“ceded ever-greater control over their territories” to this group, resulting in
“a hybrid criminal state that is perpetrating an invasion of and predatory
incursion into the United States, and which poses a substantial danger to the
United States.” 90 Fed. Reg. at 13033. The President said that “TdA has
3
Case: 25-10534 Document: 366-1 Page: 4 Date Filed: 08/13/2026
No. 25-10534
engaged in and continues to engage in mass illegal migration to the United
States”; has “invaded the United States and continues to invade, attempt to
invade, and threaten to invade the country; [has] perpetrated irregular
warfare within the country; and [has] used drug trafficking as a weapon
against our citizens.” Id.
Invoking “the full extent of [his] authority to conduct the Nation’s
foreign affairs under the Constitution,” the President “f[ound] and
declare[d] that TdA is perpetrating, attempting, and threatening an invasion
or predatory incursion against the territory of the United States.” Id. at
13034. TdA is accomplishing this, according to the Proclamation, by
“undertaking hostile actions and conducting irregular warfare against the
territory of the United States both directly and at the direction, clandestine
or otherwise,” of the then-current Venezuelan government. Id. The
President thus “proclaim[ed] that all Venezuelan citizens 14 years of age or
older who are members of TdA, are within the United States, and are not
actually naturalized or lawful permanent residents of the United States are
liable to be apprehended, restrained, secured, and removed as [a]lien
[e]nemies” under the AEA. Id.
The President directed that all such individuals “are subject to
immediate apprehension, detention, and removal, and further that they shall
not be permitted residence in the United States.” Id. Moreover, the
Proclamation stated, “[t]he Secretary of Homeland Security retains
discretion to apprehend and remove any [a]lien [e]nemy under any separate
authority.” Id.

W.M.M., F.G.M., and A.R.P.—three “Venezuelan national[s]”
whom the government alleges are TdA members and who were then detained

in Anson, Texas—filed a habeas petition. 1 Specifically, they purported to file
a habeas petition as a class action. Indeed, their habeas petition bears the title
“Complaint-Class Action: Class Petition for Writ of Habeas Corpus and
Complaint for Declaratory and Injunctive Relief.” 2 They claim, among other
things, that the Proclamation does not satisfy the AEA and violates due
process. They also moved to certify a class of “[a]ll noncitizens in custody
in the Northern District of Texas who were, are, or will be subject to” the
President’s Proclamation “and/or its implementation.”
Almost immediately, litigation in this case assumed a breakneck pace.
On April 17, 2025, the day after petitioners filed their habeas petition, the
district court denied their motion, on their own behalf and that of the putative
class, for a temporary restraining order “against summary removal under the
AEA.” A.A.R.P. v. Trump (A.A.R.P. III), 605 U.S. 91, 92 (2025). The next
day, April 18, at 12:34 a.m. central time, petitioners moved for an emergency
TRO—again on their own behalf and that of the putative class. Id. At 12:48
p.m., they asked for “a ruling on that motion or a status conference by 1:30
p.m.” Id. At 3:02 p.m., they appealed the district court’s “constructive
denia[l]” of the emergency TRO to our court and sought a temporary
administrative stay and an injunction pending appeal. Id. at 92–93 (alteration

The district court granted the named petitioners’ motion to proceed under
pseudonyms. In district court, A.R.P. initially went by the initials “A.A.R.P.,” but the
district court granted a motion to change his pseudonym to “A.R.P.”
2
Generally, habeas proceedings involve only one petitioner against one
respondent. See, e.g., Rumsfeld v. Padilla, 542 U.S. 426, 434 (2004) (“[T]he proper
respondent to a habeas petition is ‘the person who has custody over [the petitioner].’ The
consistent use of the definite article in reference to the custodian indicates that there is
generally only one proper respondent to a given prisoner’s habeas petition.” (second
alteration in original) (citation omitted) (quoting 28 U.S.C. § 2242)). But W.M.M. and
A.R.P. filed a single habeas petition together and also sought to represent a putative class.
They later filed an amended habeas petition adding F.G.M. as a third petitioner.

Case: 25-10534 Document: 366-1 Page: 6 Date Filed: 08/13/2026
No. 25-10534
in original). The same day, petitioners also submitted to the Supreme Court
an emergency application for an emergency injunction or writ of mandamus
and stay of removal, seeking to bar the government from removing them
while the appeal was pending, as well as a class-wide temporary
administrative injunction. Id. at 93. Petitioners posited that the Supreme
Court could alternatively treat their application as a petition for certiorari
before judgment.
That night, our court dismissed petitioners’ appeal for lack of
jurisdiction under 28 U.S.C. § 1291(a)(1) and denied their motion for a
temporary administrative stay and an injunction pending appeal as
premature. A.A.R.P. v. Trump (A.A.R.P. I), No. 25-10534, 2025 WL 1148141,
at *1 (5th Cir. Apr. 18, 2025). At the time of that order, the panel was
unaware that the Supreme Court would also issue a ruling the same night. At
12:52 a.m. on April 19—that is, 11:52 p.m. central time on April 18—the
Supreme Court ordered the government “not to remove any member of the
putative class of detainees.” A.A.R.P. III, 605 U.S. at 93; A.A.R.P. v. Trump
(A.A.R.P. II), 145 S. Ct. 1034, 1034 (2025). It invited the government to
respond to the stay application after our court had ruled. A.A.R.P. II, 145 S.
Ct. at 1034. The case then returned to district court.
In the brief lull that followed, the district court denied class
certification. But it stayed the effect of that denial “pending further action
from the Supreme Court.” And it declared that if the Supreme Court
granted petitioners’ then-pending “petition for a writ of certiorari” (by
which it presumably meant their application for emergency relief), the
district court’s order denying certification would “[be] automatically
vacated.” That is indeed what happened when the Supreme Court treated
petitioners’ pending emergency-relief application as a petition for certiorari
and granted it. A.A.R.P. III, 605 U.S. at 94, 97 n.1, 98. The putative class
6
Case: 25-10534 Document: 366-1 Page: 7 Date Filed: 08/13/2026
No. 25-10534
currently remains uncertified. Id. at 97 n.1; W.M.M. v. Trump, 154 F.4th 207,
213 & n.2, vacated on grant of en banc reh’g, 154 F.4th 319 (5th Cir. 2025).
The Supreme Court vacated our judgment dismissing petitioners’
appeal and remanded the case to us. A.A.R.P. III, 605 U.S. at 98. It
concluded that we had incorrectly dismissed the appeal for lack of
jurisdiction. Id. at 94. The Court then directed that “[i]n resolving the
detainees’ appeal,” we “should address” two questions:
(1) all the normal preliminary injunction factors, including
likelihood of success on the merits, as to the named plaintiffs’
underlying habeas claims that the AEA does not authorize their
removal pursuant to the President’s March 14, 2025,
Proclamation, and (2) the issue of what notice is due, as to the
putative class’s due process claims against summary removal.
Id. at 98–99.
The Court enjoined the government “from removing the named
plaintiffs or putative class members in this action under the AEA pending
order by the Fifth Circuit and disposition of” a timely petition for a writ of
certiorari. Id. at 99. But it expressly stated that the government “may remove
the named plaintiffs or putative class members under other lawful
authorities.” Id.
On remand, a panel of our court granted preliminary injunctive relief
to the three named petitioners and to the putative class. W.M.M., 154 F.4th
at 213. It also concluded that the government’s notice procedure satisfied
due process. Id. At the government’s request, we granted en banc review.
At oral argument before the en banc court, we inquired as to the
current immigration statuses of the three named petitioners. Neither
petitioners’ counsel nor the government’s was able to provide a full answer.
Specifically, counsel for petitioners told the court that while two of the
named petitioners had been removed “under the immigration laws,” he did
7
Case: 25-10534 Document: 366-1 Page: 8 Date Filed: 08/13/2026
No. 25-10534
not know the status of his last remaining client. Oral Arg. at 22:54–25:48,
27:20–28:42. Counsel for the governmental defendants, which include the
Department and Secretary of Homeland Security, was no wiser. Oral
Arg. at 54:13–55:29. The named petitioners expressly declined to protest
their removal.
Counsel have since provided some of the missing and desired
information. At the court’s request, counsel for petitioners and for the
government jointly notified us, without further explanation, that “[t]he
government has removed all three named [p]etitioners—W.M.M., []A.R.P.,
and F.G.M.—under the Immigration and Nationality Act.” As a result, no
petitioner remains in this country, and no class has been certified.
II
The Supreme Court remanded this case to us when the three named
petitioners were still in the country. But we have since learned that the
government has removed them. Given this change, we conclude that the
appeal is moot.
“[I]f in the course of litigation a court finds that it can no longer
provide a plaintiff with any effectual relief, the case generally is moot.”
Uzuegbunam v. Preczewski, 592 U.S. 279, 282 (2021); accord, e.g., Chafin v.
Chafin, 568 U.S. 165, 172 (2013) (explaining that a case “becomes moot only
when it is impossible for a court to grant any effectual relief whatever to the
prevailing party” (quoting Knox v. Serv. Emps. Int’l Union, Loc. 1000,
567 U.S. 298, 307 (2012))). And “if an event occurs while a case is pending
on appeal that makes it impossible for the court to grant ‘any effectual relief
whatever’ to a prevailing party, the appeal must be dismissed.” Church of
Scientology of Cal. v. United States, 506 U.S. 9, 12 (1992) (quoting Mills v.
Green, 159 U.S. 651, 653 (1895)). The government has removed all three
named petitioners under the INA, so enjoining removal under the AEA
8
Case: 25-10534 Document: 366-1 Page: 9 Date Filed: 08/13/2026
No. 25-10534
would not prevent their removal. See Preczewski, 592 U.S. at 282. And AEA
removal of the three named petitioners now cannot occur, irrespective of any
preliminary injunction in this case. The appeal has thus become moot. See
Church of Scientology, 506 U.S. at 12.
We note that petitioners—to the extent that any party can now
properly receive that appellation—have asked us to substitute five new class
representatives on appeal in place of the three that no longer remain in this
country and as to whom the appeal is now moot. We decline to do so for the
reasons that the separate order on that motion expresses. While an exception
to the mootness doctrine exists for properly certified class actions, no class
exists or ever has existed in this case. See Sosna v. Iowa, 419 U.S. 393, 399
(1975) (“When the [d]istrict [c]ourt certified the propriety of the class action, the
class of unnamed persons described in the certification acquired a legal status
separate from the interest asserted by appellant.” (emphasis added)); id. at
399 n.8; see also Gerstein v. Pugh, 420 U.S. 103, 110 n.11 (1975). Nor has the
district court—which is in a much better position than we are to make factual
determinations—had an opportunity to find any facts with respect to
whether those five proposed representatives should indeed represent the
putative class. See, e.g., Oscar Priv. Equity Invs. v. Allegiance Telecom, Inc.,
487 F.3d 261, 268 (5th Cir. 2007) (explaining that “a district court must
‘resolve[] factual disputes relevant to each Rule 23 requirement and find []
that whatever underlying facts are relevant to a particular Rule 23
requirement have been established’” (alterations in original) (quoting In re
Initial Pub. Offerings Secs. Litig., 471 F.3d 24, 41 (2d Cir. 2006)); cf. Vizena v.
Union Pac. R.R. Co., 360 F.3d 496, 502–03 (5th Cir. 2004) (recognizing the
“essentially factual basis of the certification inquiry,” including the
determination that the Rule 23 requirements “are met,” and “of the district
court’s inherent power to manage and control pending” litigation (quoting
Allison v. Citgo Petroleum Corp., 151 F.3d 402, 408 (5th Cir. 1998))). But, as
9
Case: 25-10534 Document: 366-1 Page: 10 Date Filed: 08/13/2026
No. 25-10534
the court’s separate order explains, the denial of the motion to add class
representatives on appeal is without prejudice to any future determination by
the district court respecting whether to certify a class, to permit the
petitioners to add or substitute new class representatives, or to allow an
amendment of the petition. 3
Given the lack of any named petitioners to whom we could grant relief
in this appeal, and given that this case has never and does not now feature
any class, we conclude that the appeal is moot. We therefore DISMISS the
appeal for lack of jurisdiction.

The “general rule of mootness . . . is that a class action becomes moot when the
putative representative plaintiff’s claim has been rendered moot before a class is certified.”
Fontenot v. McCraw, 777 F.3d 741, 748 (5th Cir. 2015); accord, e.g., Slayman v. FedEx Ground
Package Sys., 765 F.3d 1033, 1048 (9th Cir. 2014) (“[W]here, as here, the plaintiff’s claim
becomes moot before the district court certifies the class, the class action normally also
becomes moot.” (citations omitted)). Obviously, exceptions exist to that general rule. See
generally, e.g., 13C Wright & Miller’s Federal Practice & Procedure § 3533.9.1 (3d ed. Apr.
2026 update). But no one in this case argues that any exception to mootness applies.
10
Case: 25-10534 Document: 366-1 Page: 11 Date Filed: 08/13/2026
No. 25-10534
James C. Ho, Circuit Judge, concurring:
I agree that this case is moot. But I also agree with the United States
that we should address the merits questions directed to us by the Supreme
Court—and affirm the President’s actions under the Alien Enemies Act and
the Due Process Clause. See A.A.R.P. v. Trump, 605 U.S. 91, 98–99 (2025).
Mootness is, of course, jurisdictional—and ordinarily, we must find
jurisdiction first, before reaching the merits. But when it comes to appeals at
the preliminary injunction stage, there is no order of operations. We can deny
relief based on the merits, instead of jurisdiction—as our en banc court did
in United States v. Abbott, 110 F.4th 700, 722 (5th Cir. 2024). In fact, the
Supreme Court has instructed that reaching the merits in cases like this is not
just permissible, but “most appropriate.” Munaf v. Geren, 553 U.S. 674, 691
(2008). After all, “the injunction rests on a question of law and it is plain that
the plaintiff cannot prevail.” Id. If “the Government is entitled to judgment
as a matter of law, it is appropriate for us to terminate the litigation now.” Id.
at 692 (emphasis added). See also Roake v. Brumley, 170 F.4th 292, 300–01
(5th Cir. 2026) (Ho, J., concurring) (discussing Abbott and Munaf).
And that’s what the Government is asking us to do here—terminate
the litigation now, by ruling on the merits as a matter of law.
***
As I’ve explained, foreign governments have used illegal immigration
as a weapon to invade and weaken other countries, as Administrations of both
parties have warned for decades. See United States v. Texas, 173 F.4th 659,
668–72 (5th Cir. 2026) (Ho, J., concurring); Abbott, 110 F.4th at 734 (Ho, J.,
concurring in the judgment in part and dissenting in part). As I’ve also noted,
judges are supposed to defer to a President’s declaration of a state of
invasion—including the ones issued on January 20, 2025. See Texas, 173
F.4th at 671 (Ho, J., concurring); Abbott, 110 F.4th at 728–29 (Ho, J.,
11
Case: 25-10534 Document: 366-1 Page: 12 Date Filed: 08/13/2026
No. 25-10534
concurring in the judgment in part and dissenting in part); see also
Proclamation No. 10888, Guaranteeing the States Protection Against Invasion,
90 Fed. Reg. 8333, 8334 (Jan. 20, 2025) (“I have determined that the current
state of the southern border reveals that the Federal Government has failed
in fulfilling this obligation to the States and hereby declare that an invasion is
ongoing at the southern border.”); Exec. Order No. 14159, Protecting the
American People Against Invasion, 90 Fed. Reg. 8443 (Jan. 20, 2025).
And if courts must defer when the President treats illegal immigration
as an invasion, see id., then a fortiori we must defer when it comes to the
narrower question of an invasion by Tren de Aragua. See Proclamation No.
10903, Invocation of the Alien Enemies Act Regarding the Invasion of The United
States by Tren de Aragua, 90 Fed. Reg. 13033 (Mar. 14, 2025).
So I would answer the Court’s questions and affirm Proclamation
10903 and the President’s actions under the Alien Enemies Act and the Due
Process Clause. That would not just “terminate the litigation now.” Munaf,
553 U.S. at 692 (emphasis added). It would also terminate future AEA cases,
such as those involving the putative class members—as well as any number
of other cases and controversies that likewise turn on a state of invasion. 1

No. 25-10534
I.
I’ll begin with a basic principle: Determining the existence of a state
of invasion is a quintessentially executive prerogative—not a judicial one.
As Justice Story observed: “The command and application of the
public force . . . to resist foreign invasion, are powers so obviously of an
executive nature, and require the exercise of qualities so peculiarly adapted
to this department, that a well-organized government can scarcely exist,
when they are taken away from it.” Joseph Story, Commentaries on
the Constitution of the United States § 1485 (1833). See
also Montesquieu, The Spirit of the Laws 151 (Thomas Nugent
transl. 1899) (1748) (noting that the executive “provides against
invasions”). So “[i]f a war be made by invasion of a foreign nation, the
President is not only authorized but bound to resist force by force . . . without
waiting for any special legislative authority.” The Prize Cases, 67 U.S. (2
Black) 635, 668 (1862).
And the power to resist invasion necessarily includes the power to find
an invasion. The duty to “resist force,” id., naturally requires that “the
executive possesses the power authoritatively to find the facts when an
emergency, such as an invasion or an insurrection, arises.” Atlee v. Laird,
347 F. Supp. 689, 705 (E.D. Pa. 1972) (three-judge panel), sum. aff’d sub nom.
Atlee v. Richardson, 411 U.S. 911 (1973). “The status of . . . foreign invasion
of our own country, and insurrection at home, are political questions
determined by the executive branch of our government.” The Tropic Wind,
28 F. Cas. 218, 220 (C.C.D.D.C. 1861).
The judiciary, by contrast, is poorly suited to second-guess such
matters. “Under Article II of the Constitution, the President of the United
States, not any federal judge, is the Commander in Chief of the Armed
Forces.” Austin v. U.S. Navy Seals 1-26, 142 S. Ct. 1301, 1302 (2022)
13
Case: 25-10534 Document: 366-1 Page: 14 Date Filed: 08/13/2026
No. 25-10534
(Kavanaugh, J., concurring). So judges may not review the President’s
determination of an invasion.
II.
These principles readily apply to the Alien Enemies Act, and inform
the statutory interpretation issues presented in this case.
The Act authorizes the President to detain and remove enemy aliens
when there is either “a declared war between the United States and any
foreign nation or government,” or “any invasion or predatory incursion is
perpetrated, attempted, or threatened against the territory of the United
States by any foreign nation or government,” and “the President makes
public proclamation of the event.” 50 U.S.C. § 21 (emphases added).
It’s undisputed that courts have no power to question a Congressional
declaration of war. Courts may ask if Congress has declared war—but we do
not look behind the declaration and ask whether we agree that there is a
legitimate war at hand. See, e.g., John C. Yoo, The Continuation of Politics by
Other Means: The Original Understanding of War Powers, 84 Calif. L. Rev.
167, 295 (1996) (“Congress’ power to declare war . . . deprives the courts of
the ability to second-guess Congress’ determination of whether a formal state
of war exists.”).
Counsel for Petitioner admitted as much during oral argument. He
acknowledged that courts must defer to Congressional declarations of war
under Ludecke v. Watkins, 335 U.S. 160 (1948). See Oral Arg. at 8:09–11:00.
But he theorized that a Presidential proclamation of invasion doesn’t warrant
the judicial respect that a Congressional declaration of war deserves. Id.
That curious (if not counterintuitive) hierarchy conflicts with the text
of the Alien Enemies Act. It also turns the war powers of the United States
on its head. As a matter of statutory interpretation as well as separation of
14

powers, there’s no basis for requiring courts to defer to a Congressional
declaration of war, but not a Presidential proclamation of invasion.
A.
When statutory terms appear together, we typically construe them
together, unless the text indicates otherwise. Under the noscitur a sociis
canon, when words “are associated in a context suggesting that the words
have something in common, they should be assigned a permissible meaning
that makes them similar.” Antonin Scalia & Bryan A. Garner, Reading
Law: The Interpretation of Legal Texts 195 (2012). That’s
clearly the case here, where all three statutory triggers empower the
President to respond to a potential national security threat. Likewise, we
interpret related statutory terms in pari materia—that is, we treat “laws
dealing with the same subject . . . harmoniously.” Id. at 252. When a
“phrase that comes before a court for interpretation is part of the whole
statute,” its meaning is “affected by other provisions of the same statute.”
Id. “Our task is to give all of it . . . the most harmonious, comprehensive
meaning possible.” Clark v. Uebersee Finanz-Korporation, A.G., 332 U.S.
480, 488 (1947).
So it would defy the text and structure of the AEA to defer to Congress
declaring the need for offensive military actions—but not to the President
engaging in defensive military actions to protect the homeland. “We
generally ‘resist attributing to Congress an intention to render a statute so
internally inconsistent.’” Jones v. Hendrix, 599 U.S. 465, 479 (2023)
(citation omitted).
Moreover, the AEA doesn’t even mention Congress—it mentions
only the President. Under the Presidential avoidance canon, courts presume
that statutes do not apply to the President absent express reference. See, e.g.,
Franklin v. Massachusetts, 505 U.S. 788, 800–01 (1992) (“Out of respect for
15
Case: 25-10534 Document: 366-1 Page: 16 Date Filed: 08/13/2026
No. 25-10534
the separation of powers and the unique constitutional position of the
President, we find that textual silence is not enough to subject the President
to the provisions of [an act].”); Nixon v. Fitzgerald, 457 U.S. 731, 748 n.27
(1982) (requiring an explicit statement from Congress before applying
generally applicable statutes to the President). By that same logic, when a
statute explicitly authorizes the President (and only the President) to take
certain action, that too warrants “respect for the separation of powers and
the unique constitutional position of the President.” Franklin, 505 U.S. at
800–01.
B.
This understanding of the AEA is further bolstered by the
Constitution and its allocation of war powers across the separate branches of
government.
Under the Constitution, the President is the Commander in Chief. He
alone is vested with the executive power, and entrusted with taking care that
the laws be faithfully executed. Numerous Presidents have asserted this
authority to take independent military action on countless occasions. See,
e.g., Barbara Salazar Torreon & Sofia Plagakis, Instances of Use of United States
Armed Forces Abroad, 1798-2023, Cong. Research Serv. (2023). As
President John Quincy Adams observed in the early years of our Republic:
“However startled we may be at the idea that the Executive Chief Magistrate
has the power of involving the nation in war, even without consulting
Congress, an experience of fifty years has proved that in numberless cases he
has and must have exercised the power.” John Quincy Adams, An
Eulogy on the Life and Character of James Madison 47
(1836). See also, e.g., The Federalist No. 74 (Alexander Hamilton)
(“Of all the cares or concerns of government, the direction of war most
16
Case: 25-10534 Document: 366-1 Page: 17 Date Filed: 08/13/2026
No. 25-10534
peculiarly demands those qualities which distinguish the exercise of power
by a single hand.”).
Congress has the power to declare war. So Congress can “define the
legal state of our relations with another country under international law.”
Robert J. Delahunty & John Yoo, Making War, 93 Cornell L. Rev. 123,
127 (2007). The Founders also “granted Congress an ultimate check on
executive actions . . . by exercising its powers over funding and
impeachment.” Yoo, The Continuation of Politics by Other Means, at 174. But
“the Commander in Chief Clause is a grant of power that makes clear that
the Executive still retains the bulk of the war power, minus whatever Article
I, Section 8 conveys to Congress.” Delahunty & Yoo, Making War, at 129.
This broad understanding of the President’s powers as Commander
in Chief is further bolstered by other provisions of the Constitution. For
example, “Article I, Section 10, Clause 3, expressly prohibits states from
‘engag[ing] in War, unless actually invaded, or in such imminent Danger as
will not admit of delay’ unless they have obtained the ‘Consent of
Congress.’” James C. Ho and John C. Yoo, The Sword and the Purse (Part 2);
The President as Commander in Chief, Heritage Foundation (June 20,
2011). “By contrast, no such limitation on engagement in war by the
President can be found in Article II.” Id. “Article II expressly authorizes the
President to engage in other foreign relations powers (such as the making of
treaties and the appointment of ambassadors) only with the consent of
Congress”—yet “it imposes no such check with respect to the use of military
force.” Id.
C.
Moreover, it’s precisely because the Constitution vests such broad
war powers in the President that the Founders were uniquely concerned
about foreign influence over the Presidency.

The Constitution limits the office of President to natural born citizens.
See U.S. Const. art. II, § 1, cl. 5 (“No Person except a natural born Citizen
. . . shall be eligible to the Office of President”). No other federal office is
limited in this matter. The Constitution only “requires that a President be a
citizen from birth.” Trump v. Barbara, 609 U.S. _, _ (2026) (Alito, J.,
dissenting). And the reason is the enormity of the President’s powers as our
Commander in Chief.
In a letter to George Washington during the Constitutional
Convention, John Jay argued that it would be “wise & seasonable to provide
a strong check to the admission of Foreigners into the administration of our
national Government; and to declare expresly that the Command in chief of
the american army shall not be given to, nor devolved on, any but a natural
born Citizen.” Letter from John Jay to George Washington (July 25, 1787), 3
Max Farrand, The Records of the Federal Convention of
1787, at 61 (1911) (emphasis in original). Washington thanked Jay for his
recommendation in a September 2, 1787 letter. Id. at 76. And two days later,
the Committee on Detail “reported its version of the presidential eligibility
provision with ‘natural born Citizen’ to the Convention at large.” Thomas
H. Lee, Natural Born Citizen, 67 Am. U. L. Rev. 327, 353 (2017).
Notably, Jay’s letter “specifically addressed the President’s role as
military commander, not as head of state or chief executive of the domestic
political order.” Id. at 355. Because Jay was chiefly concerned that a
foreigner might be elected “with strong sympathies with the republican cause
in Europe who would then seek to deploy American armies in aid of
revolutionary war there.” Id. at 357. “[T]wo fundamental, inter-related
concerns animat[ed]” the Natural Born Citizens Clause: “preventing
European intervention in American domestic politics,” and “preventing
American military intervention in European domestic politics.” Id.

That’s why the Founders deemed it “indispensable” that “the
president should be a natural born citizen of the United States.” Story,
Commentaries § 1473. See also Barbara, 609 U.S. at _ (Alito, J.,
dissenting) (noting that the Founders sought to “prevent a person with
possible foreign loyalties from becoming President”).
D.
So “if ever there was a place for deference to the Executive when it
comes to interpreting legal texts, it would be here, in the immigration and
border security context.” Rodriguez v. Garland, 31 F.4th 935, 945 (5th Cir.
2022) (Ho, J., dissenting from denial of rehearing en banc).
The Supreme Court has repeatedly instructed the judiciary to respect
the determinations of Congress and the President in the military context.
See, e.g., Rostker v. Goldberg, 453 U.S. 57, 64–65 (1981) (“perhaps in no other
area has the Court accorded Congress greater deference”). But “great
deference” is due “even when the President acts alone in this area.”
Boumediene v. Bush, 553 U.S. 723, 832 (2008) (Scalia, J., dissenting). “The
President, after all, is the ‘Commander in Chief of the Army and Navy of the
United States.’” Dep’t of Navy v. Egan, 484 U.S. 518, 527 (1988). That
authority over our national security “flows primarily from this constitutional
investment of power in the President
