The U.S. Supreme Court heard oral arguments on April 1 regarding President Donald Trump’s executive order limiting birthright citizenship, with the president attending the session.
Trump’s appearance marked the first time a sitting president has attended oral arguments at the Supreme Court, according to records from the high court and the nonprofit Supreme Court Historical Society. The case, Trump v. Barbara, centers on an executive order signed by Trump upon returning to office on Jan. 20, 2025, which sought to change how the 14th Amendment is interpreted concerning birthright citizenship.
Observers say this development is significant because it addresses both legal doctrine and fundamental questions about American identity and constitutional law. Robert Schmuhl, professor emeritus of American studies at the University of Notre Dame, said Trump’s attendance “raises profound questions about the American constitutional system, with its separation of powers among the executive, legislative and judicial branches of government.” Schmuhl added: “If the president is trying to ‘work the refs,’ as they say in sports, one can only hope that the justices concentrate on the case and the arguments rather than one person sitting in the audience.”
The executive order aimed to end automatic citizenship for children born in America unless at least one parent was a U.S. citizen or lawful permanent resident. The policy was challenged immediately after its announcement. Previously, federal judges’ ability to issue nationwide injunctions against such orders was limited by a Supreme Court decision; however, that ruling did not address this specific policy’s merits.
During oral arguments Solicitor General John Sauer defended Trump’s position by referencing international examples of so-called “birth tourism,” while Chief Justice John Roberts responded: “Well, it is a new world… It’s the same Constitution.” Justice Amy Coney Barrett questioned interpretations of jurisdiction under existing law.
Anna Gallagher, executive director of Catholic Legal Immigration Network (CLINIC), said: “Today’s arguments before the Supreme Court of the United States underscore what is at stake, not just a legal doctrine but a defining promise of our Constitution.” Gallagher continued: “Birthright citizenship affirms that all people born on this soil belong here fully and equally… any effort to weaken it threatens both rule of law and dignity of our communities.” CLINIC stated Gallagher attended proceedings in solidarity.
Cecillia Wang from ACLU argued against restricting birthright citizenship: “Ask any American what our citizenship rule is and they’ll tell you everyone born here is a citizen alike.” She added that exceptions are limited by precedent: “They can’t go below that floor that Constitution sets,” she said.
A decision in Trump v. Barbara is expected before June when this term ends.
