Trump Signs Executive Order Attempting to End Birthright Citizenship -- Directly from Project 2025 Mandate (2025-01-20)

On his first day in office, Trump signed Executive Order 14160 attempting to end birthright citizenship for children born in the United States to undocumented immigrants and certain visa holders, a policy directly drawn from Project 2025 Mandate Chapter 5 (Department of Homeland Security). The order was immediately challenged in multiple federal courts by states, civil rights organizations, and immigrant advocacy groups. On December 5, 2025, the Supreme Court granted certiorari in Trump v. Barbara to hear the case. The order represented the most aggressive test of whether a century-old constitutional interpretation could be reversed by executive action alone.
