The House passed one of Republicans' signature issues for the year on Thursday, approving legislation to require proof of U.S. citizenship when registering to vote for federal elections, one of President Donald Trump's top election-related priorities. Nearly all Democrats lined up against the bill and warned that it risks disenfranchising millions of Americans who do not have ready access to the proper documents. Trump has long signaled a desire to change how elections are run in the U.S. and last month issued a sweeping executive order that included a citizenship requirement among other election-related changes. Republicans argued the legislation, known as the Safeguard American Voter Eligibility Act, is necessary to ensure only citizens vote in U.S. elections and would cement Trump’s order into law. U.S. Rep. Bryan Steil, a Wisconsin Republican who chairs the House committee that handles election legislation, said during Thursday's debate that the bill is meant to “restore Americans’ confidence in our elections” and prevent noncitizens from voting. This marks Republicans’ second attempt at passing the SAVE Act. It passed the House last year but failed in the Senate amid Democratic opposition. It’s unlikely to fare any better this year. While Republicans won control of the Senate last fall, they have a narrow majority that falls short of the 60 votes they would need to overcome a filibuster. Republicans hammered on the issue during last year’s presidential election, even though voting by noncitizens is rare, already is illegal and can lead to felony charges and deportation. The SAVE Act would require all applicants using the federal voter registration form to provide documentary proof of citizenship in person at their local election office. Among the acceptable documents are a valid U.S. passport and a government-issued photo ID card presented alongside a certified birth certificate. Democrats and voting rights groups warn the legislation could lead to widespread voter disenfranchisement if it were to become law. The Brennan Center for Justice and other groups estimated in a 2023 report that 9% of U.S. citizens of voting age, or 21.3 million people, do not have proof of their citizenship readily available. Almost half of Americans don’t have a U.S. passport.
