President Donald J. Trump attended U.S. Supreme Court arguments on April 1, 2026 [1], regarding his effort to limit birthright citizenship.

The case challenges the legal doctrine based on the 14th Amendment, which grants citizenship to those born in the U.S. Trump argues that this practice encourages illegal immigration.

Trump appeared in person at the Supreme Court in Washington, D.C. [2], to watch the proceedings. The president said he would be there in person to watch the arguments [3]. During the process, Trump said birthright citizenship is a "disgrace" [3].

The legal battle centers on an executive order issued by the president to restrict the application of the 14th Amendment. Trump's goal is to have the Court overturn the long-standing interpretation of the doctrine.

Observers of the proceedings noted that the Court appeared poised to reject the restrictions [4]. Trump said, "The Court looks poised to reject my limits on birthright citizenship, which is exactly what we need" [4].

This appearance marks a rare instance of a sitting president attending oral arguments for a case directly stemming from his own executive actions. The proceedings focused on whether an executive order can override the constitutional guarantee of citizenship by birth.

"Birthright citizenship is a disgrace."

This case represents a direct challenge to one of the most fundamental pillars of U.S. citizenship law. If the Supreme Court were to uphold the president's limits, it would fundamentally alter the 14th Amendment's application, potentially stripping citizenship from children born in the U.S. to non-citizen parents, and shifting the legal definition of national belonging.
