U.S. Supreme Court Takes Up RNC Case Defending Proof of Citizenship Voting Requirement

Press Release

WASHINGTON, D.C. – Today, the Supreme Court agreed to hear the Republican National Committee's (RNC) case defending Arizona's commonsense proof of citizenship requirement and the fundamental principle that only American citizens should vote in American elections.

 

"Only American citizens should vote in American elections. It's the law and it's supported by the overwhelming majority of Americans,” said RNC Chairman Joe Gruters. “Democrats sued to block Arizona's proof of citizenship law and stop the state from removing noncitizens from its voter rolls. The RNC is proud to lead this effort, and we will keep fighting nationwide to defend election integrity and ensure only eligible citizens cast a ballot.”

Background:


  • In 2004, Arizona voters passed Proposition 200, which mandates that residents provide satisfactory evidence of U.S. citizenship when registering to vote for the first time.
  • Today’s case stems from Arizona’s 2022 election integrity law, House Bill 2492, which safeguards the state’s voter registration process by ensuring only eligible U.S. citizens can register to vote.
  • This law empowers state officials to verify citizenship, allows them to remove non-citizens from its rolls, and restores trust in Arizona election processes.
  • In August 2024, the Supreme Court of the United States correctly allowed Arizona to continue enforcing this law.
  • In October 2024, the Supreme Court permitted the Commonwealth of Virginia to remove non-citizens from its rolls leading up to the 2024 election.
  • In February 2025, the Ninth Circuit Court of Appeals ignored the Supreme Court's direction in both the Arizona and Virginia cases and sided with the Democratic National Committee and advocacy groups like Mi Familia Vota by upholding a block on key provisions of Arizona's 2022 election integrity laws.
  • This panel decision undermines Arizona’s constitutional authority to secure its own elections.
  • This lawsuit follows RNC efforts defending President Trump’s election integrity Executive Order as well as other key victories in North Carolina, Georgia, Michigan, and Texas.
