Trump Attends Supreme Court Arguments on Birthright Citizenship Order

Donald Trump walked into the Supreme Court Tuesday without a designated seat. Having no official place in the chamber, he sat among ordinary visitors as the justices heard arguments in a case bearing his name, one that could redefine American identity in ways unseen since the Civil War era.

Both the Supreme Court and the Supreme Court Historical Society confirmed there is no record of any prior sitting president attending oral arguments. Trump left the White House shortly after 9:30 a.m., telling reporters the day before, "I'm going. Because I have listened to this argument for so long." White House press secretary Karoline Leavitt confirmed his attendance.

The case, formally titled Trump v. Barbara, challenges Executive Order 14160, which Trump signed on January 20, 2025, his first day back in office. The order directs the Secretaries of State and Homeland Security, the Attorney General, and the Commissioner of Social Security to refuse to recognize U.S. citizenship for children born on American soil if their father is not a citizen or lawful permanent resident and their mother is either undocumented or present only on a temporary visa.

The scale of what hangs in the balance is substantial. Pew Research Center data from March 2026 shows that in 2023 approximately 320,000 babies, about 9% of all U.S. births, were born to mothers who were unauthorized immigrants or held temporary legal status. A coalition of 18 states, the District of Columbia, and San Francisco, which sued to block the order, warned that more than 150,000 children per year would lose citizenship status under its terms.

The constitutional fight centers on the 14th Amendment's Citizenship Clause, ratified in 1868 as a direct repudiation of the 1857 Dred Scott v. Sandford ruling, which had denied citizenship to Black Americans. Solicitor General D. John Sauer argued for the administration that children born to parents not "fully subject" to U.S. law fall outside its protection. ACLU National Legal Director Cecillia Wang argued for the challengers, framing the case as a defense of birthright citizenship for every child born in the United States.

The governing precedent is United States v. Wong Kim Ark, a 6-2 ruling from 1898 affirming that Wong, born in San Francisco to Chinese immigrant parents, was a U.S. citizen. The ACLU argues the decision "conclusively" settled the matter. The Trump administration disputes that reading.

Every lower court that considered the executive order blocked it, and no child has yet been subject to its terms. The Supreme Court's June 27, 2025 ruling in Trump v. CASA resolved only the narrower question of nationwide injunctions, leaving the birthright citizenship question for this case.

If the administration prevails, the Penn State Population Research Institute projects 2.7 million more people living in the U.S. without legal status by 2045, as those denied citizenship could not pass it to their own children. Civil rights organizations also warn some denied children could be rendered entirely stateless. Bruce Lesley, president of First Focus on Children, who filed an amicus brief, said the children at the center of the debate have gone largely unacknowledged: "The word child does not cross their lips."

Trump's courtroom appearance came weeks after he had made pointed public criticisms of certain justices following his rare loss in a tariffs case. The Court accepted Trump v. Barbara in December 2025; a ruling is expected before the end of the term.
