A significant legal development has occurred in Arizona concerning voter registration and election integrity. The Ninth Circuit Court of Appeals has ruled that Arizona voters must provide proof of citizenship to register to vote, a decision that has been hailed as a victory for election integrity by various groups. This ruling comes despite objections from Democrats and follows threats of legal action from America First Legal against Arizona counties to ensure that only U.S. citizens are on voter rolls. The group, headed by a former Trump advisor, has been actively working to prevent illegal aliens from voting in the state. Additionally, over 35,000 individuals who registered using a federally approved form that does not require proof of citizenship are now under scrutiny. The decision is seen as a win for the Arizona GOP and election integrity advocates. Notably, the Ninth Circuit also denied key portions of a Republican motion to stay a trial court victory in a voter suppression lawsuit.
