Gov. Ron DeSantis (R-FL) signed legislation Wednesday requiring proof of U.S. citizenship to register to vote, advancing a state-level version of the proposed federal Safeguard American Voter Eligibility Act.

The measure, backed by Republican lawmakers, requires individuals registering to vote in Florida to provide documentary proof of citizenship, such as a passport or birth certificate. The move comes after Florida Democrats flipped two seats in the state legislature in special elections on March 24.
