Four states have now signed such legislation as Trump’s Save Act languishes in Senate with little chance of passage

The governors of Florida and Mississippi signed legislation on Wednesday to require documented proof of citizenship to register to vote and to begin a process that will eventually unenroll voters who have not provided citizenship documentation.

Four states have now passed proof-of-citizenship laws for voting this year, after South Dakota and Utah’s governors each signed proof of citizenship bills into law in March.

The changes come as Donald Trump’s signature restrictive voting bill, the Save America Act, languishes in the US Senate with little chance of passage. The president is left weighing his options about how to move forward with its provisions, which include documented proof of citizenship requirements to register and strict photo ID requirements to vote.
