In this episode of Unwritten Law, NCLA President and Chief Legal Officer Mark Chenoweth and Senior Litigation Counsel John Vecchione break down Trump v. Barbara, a closely watched case before the U.S. Supreme Court addressing the scope of birthright citizenship under the Fourteenth Amendment.

John shares firsthand insights from attending oral argument, where the Court considered whether the Constitution guarantees citizenship to all children born in the United States or whether limits may apply to the children of illegal immigrants and temporary visitors. The case stems from an executive order directing federal agencies to reinterpret the Citizenship Clause—raising both constitutional and administrative law questions.

The discussion explores the historical understanding of the Fourteenth Amendment, the role of allegiance and jurisdiction, and key precedents such as United States v. Wong Kim Ark. Mark and John also examine competing arguments presented at oral argument, including concerns about retroactivity, congressional authority, and the practical consequences of altering long-standing interpretations of citizenship.

The episode also highlights commentary from legal scholars, including an article by Philip Hamburger, and explains why the Court’s decision—expected later this term—could have major implications for immigration policy, constitutional law, and the separation of powers.
