Washington Trump Birthright Citizenship EO Challenge

A pro-democracy lawsuit challenging President Donald Trump’s Executive Order attempting to end birthright citizenship.

Background

Attorneys general from Washington, Arizona, Illinois and Oregon filed a lawsuit challenging President Donald Trump’s Jan. 20 Executive Order (EO) ending birthright citizenship. The EO limits citizenship only to children born in the United States with at least one parent who is an American citizen or lawful permanent resident. Plaintiffs assert the EO violates the Fourteenth Amendment’s Citizenship Clause and the Immigration and Nationality Act. The lawsuit seeks to block the EO’s implementation.

Why It Matters

Trump’s unprecedented challenge to one our nation’s most fundamental constitutional guarantees fits squarely within the administration’s broader anti-immigrant agenda. The EO seeks to destabilize the rule of law and limit who may be entitled to constitutional protections such as the freedom of speech and right to due process.
