On April 1, 2026, the Supreme Court heard oral arguments in Trump v. Barbara — the constitutional challenge to President Trump's January 20, 2025 executive order ending birthright citizenship for children born to undocumented parents. Trump attended the arguments in person. The most consequential exchange came when Justice Neil Gorsuch exposed a devastating logical flaw in the government's position: under the test Solicitor General D. John Sauer was proposing, the administration could not guarantee that Native American children born today would be birthright citizens.
The Gorsuch-Sauer Exchange
Gorsuch asked directly: "Do you think Native Americans today are birthright citizens under your test?"
Sauer initially responded: "I think so. I mean obviously they've been granted citizenship by statute" — referring to the Indian Citizenship Act of 1924. But Gorsuch pressed the question: under the constitutional test the government was proposing — which would limit birthright citizenship to children of noncitizens who intend to live permanently in the United States — would newly born Native American babies be entitled to citizenship without relying on the 1924 statute?
Sauer could not clearly answer yes.
The exchange was damaging because it revealed that the government's proposed reinterpretation of the 14th Amendment's citizenship clause — "All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens" — would strip constitutional protection from a group whose citizenship was already fragile. Native Americans on reservations, who the government has historically argued are subject to tribal rather than U.S. jurisdiction, would fall into precisely the constitutional gap the administration was trying to create.
Broader Context of the Arguments
The Trump administration leaned heavily on an 1884 precedent, Elk v. Wilkins, which held that a Native American born on a reservation was not a U.S. citizen by birth — a ruling predating the Indian Citizenship Act. But the Court's 1898 decision in Wong Kim Ark v. United States established the broad principle that virtually anyone born on U.S. soil is a citizen, and every lower court that examined Trump's executive order found it unconstitutional under this precedent.
Law professor Stephen Vladeck noted that Gorsuch — who has a strong track record defending Native American sovereignty and rights, including authoring the landmark McGirt v. Oklahoma (2020) decision — was "especially pointed" in his questioning and that Sauer's inability to protect Native American citizenship "may have been the most damaging moment for the government."
Trump's Attendance
Trump's decision to attend oral arguments in person was unprecedented for a sitting president in a case challenging his own executive order. The optics were striking: the president who signed the order sat watching as justices interrogated whether his administration's legal theory could strip citizenship from Native Americans.
Outlook
The case is expected to be decided by June or July 2026. The oral arguments appeared unfavorable for the government, with multiple conservative justices — not just the liberal bloc — pressing skeptical questions. If the Court rules against the administration, it would reaffirm 125+ years of settled constitutional interpretation. If it rules in favor, it would be the first time in American history that the Supreme Court narrowed the scope of birthright citizenship — affecting an estimated 150,000 children born annually.
