Voters in Arizona who register with the state and do not provide proof of citizenship will be rejected. "This is a victory for election integrity in Arizona. Only U.S. citizens should be allowed to vote in our elections. It sounds like common sense, but the radical left elected officials in our state continue to reject this notion, disrespecting the voices of our lawful Arizona voters. We are grateful the court is upholding this provision in our law, and it's time for Congress to take action to ensure only lawful U.S. citizens are voting in federal races."
