Arizona Republicans are asking the U.S. Supreme Court to enforce a law requiring proof of citizenship for voter registration, which has been stuck in legal limbo since its inception. The law was partially upheld by a trial court but reversed by the 9th Circuit Court of Appeals, prompting Republicans to file an emergency stay with Justice Elena Kagan. Concurrently, Arizona's Secretary of State Adrian Fontes is appealing a judge's ruling that blocked voter intimidation provisions in the state's elections manual, citing constitutional free speech protections. The manual had aimed to define and prevent behaviors considered intimidating at polling places, but the court found these provisions overly broad and vague. Both cases highlight ongoing tensions over voting regulations and election integrity in a key swing state ahead of the November elections.
