Trump v. Barbara: Birthright Citizenship Executive Order Case

Trump v. Barbara is the Supreme Court case, argued on April 1, 2026, that will decide whether President Donald Trump can end birthright citizenship for children born in the United States to parents who are undocumented or here on temporary visas. The case reached the Court as a nationwide class action brought on behalf of affected newborns, and a decision is expected by late June or early July 2026.

The Executive Order at the Center of the Case

On January 20, 2025, his first day back in office, President Trump signed Executive Order No. 14,160, “Protecting the Meaning and Value of American Citizenship.” It directs federal agencies to stop recognizing U.S. citizenship for children born on American soil if, at the time of birth, neither parent was a citizen or lawful permanent resident. Two groups of mothers are targeted: those unlawfully present in the country, and those lawfully present on a temporary basis, such as student, work, or tourist visas.¹

The order was written to take effect 30 days after signing, reaching children born on or after February 19, 2025. It instructs the State Department, Justice Department, Department of Homeland Security, and Social Security Administration to refuse to issue or accept documents recognizing citizenship for the affected children.¹

The legal theory rests on five words in the Fourteenth Amendment. The Citizenship Clause grants citizenship to “all persons born or naturalized in the United States, and subject to the jurisdiction thereof.” The order takes the position that children of undocumented or temporarily present parents are not “subject to the jurisdiction” of the United States in the sense the clause requires.¹

How the Case Reached the Supreme Court

Lawsuits followed within a day. A federal judge temporarily blocked the order on January 23, 2025, and by February multiple district courts had issued preliminary injunctions holding that the order likely violated both the Fourteenth Amendment and 8 U.S.C. § 1401(a), the statute codifying birthright citizenship.

The path narrowed on June 27, 2025, when the Supreme Court decided Trump v. CASA, Inc. In a 6-3 ruling by Justice Amy Coney Barrett, the Court held that universal injunctions likely exceed the equitable authority of federal courts, and that relief must be limited to what is needed to give “complete relief to each plaintiff with standing to sue.” The decision drew a line between universal injunctions and nationwide class-action injunctions, which come with the safeguards of Rule 23 class certification.²

The same day CASA came down, the ACLU and a coalition of civil rights groups filed Barbara v. Trump in the District of New Hampshire, structured this time as a class action. It returned to Judge Joseph N. Laplante, who had earlier declined to enter a nationwide injunction. He was reported to have observed the difference plainly: “I’m the judge who wasn’t comfortable with issuing a nationwide injunction. Class action is different.”³

On July 10, 2025, Judge Laplante issued a preliminary injunction and provisionally certified a nationwide class of “all children born on U.S. soil” who would be affected by the order.⁴ The order, otherwise set to take effect July 27, 2025, stayed blocked through the class-based mechanism the Supreme Court had just described as permissible.³

The government sought a writ of certiorari before judgment on September 26, 2025, asking the Court to skip the First Circuit.⁵ The Court granted review on December 5, 2025.⁶

Who the Plaintiffs Are

The case is brought under pseudonyms. The three named plaintiffs cover the immigration situations the order targets:

Barbara, a Honduran asylum applicant.
Susan, a Taiwanese citizen on a student visa, suing on behalf of her child Sarah.
Mark, a Brazilian applicant for permanent residence, suing on behalf of his child Matthew.⁷

They are represented by the ACLU, the NAACP Legal Defense and Educational Fund, the Asian Law Caucus, the Democracy Defenders Fund, and ACLU affiliates in New Hampshire, Maine, and Massachusetts.⁸

The Constitutional Question

Both sides argue from the same text, the same history, and the same 1898 precedent, United States v. Wong Kim Ark. They read them very differently.

The Administration’s Reading

Solicitor General D. John Sauer argues that the Citizenship Clause was written to overrule Dred Scott v. Sandford and secure citizenship for formerly enslaved people, not to set a universal rule for every child born on American soil. On his reading, “subject to the jurisdiction thereof” requires “complete” political jurisdiction, tied to allegiance and domicile. Parents who are undocumented cannot lawfully establish domicile, so their children fall outside the clause. He points to the Slaughter-House Cases (1873) and Elk v. Wilkins (1884) as evidence that the clause was understood narrowly in the years after ratification.⁹

The Challengers’ Reading

Cecillia D. Wang, the ACLU’s national legal director, argues that the amendment codified a longstanding common-law rule: almost anyone born on American soil is a citizen, with narrow exceptions for children of foreign diplomats or hostile occupying forces. Had the framers meant to exclude the children of non-permanent residents, they would have said so. The challengers rely centrally on Wong Kim Ark, which held in 1898 that the Fourteenth Amendment guarantees citizenship to children born in the United States regardless of race, color, or parental nationality, and on Congress’s decision to reuse the same jurisdictional language when it codified birthright citizenship in 1940 and 1952 at 8 U.S.C. § 1401.⁹ Harvard Law Professor Gerald Neuman called the executive order “doubly unlawful,” saying it violates both the Constitution and existing citizenship statutes and that the president has no authority to redefine who qualifies for citizenship on his own.¹⁰

What Happened at Oral Argument

The Court heard argument on April 1, 2026, in a session that ran just over two hours. President Trump attended in person, believed to be the first time a sitting president had done so during Supreme Court oral arguments. He told reporters he came “because I have listened to this argument for so long.”¹¹¹²

The questions from the bench pressed hard on the government’s theory. Chief Justice Roberts told Sauer, “It’s a new world. It’s the same Constitution.” Justice Gorsuch said the Fourteenth Amendment focuses on the child, not the parents, and called the absence of any domicile requirement in the historical debates “striking.” Justice Kagan asked Sauer to defend what she described as a “revisionist theory” departing from more than a century of precedent. Justice Barrett pressed him on the practical consequences: under his framework, a newborn’s citizenship could sit in limbo for years while domicile questions were sorted out. Justice Kavanaugh asked why Congress would have reused “subject to the jurisdiction thereof” in the 1940 and 1952 statutes if it had not meant to track the broad reading from Wong Kim Ark.¹³ Legal analysts read the session as tilting toward the challengers, while warning that oral argument questions do not always predict outcomes.¹⁴

Where Things Stand and What the Ruling Would Change

As of mid-2026, Executive Order 14,160 has never been enforced. Court injunctions have blocked it continuously since January 23, 2025. In the meantime, USCIS has been drafting contingency plans in case the order is ultimately upheld, including a proposal to let affected children born to parents with temporary lawful status register for the immigration status held by at least one parent, and to defer immigration enforcement against those children during any transition.¹⁵

A decision is expected by late June or early July 2026. If the Court sides with the challengers, birthright citizenship remains what it has been since Wong Kim Ark: a guarantee that reaches nearly every child born on U.S. soil. If it sides with the administration, the president will have narrowed that guarantee through executive action, and the class of newborns swept out of citizenship will include, by the ACLU’s estimate, more than 200,000 children born to immigrant parents each year.¹⁶
