Washington — The House passed a controversial bill on Thursday that would require Americans to show proof of citizenship in person to register to vote in federal elections, which critics say could disenfranchise millions of eligible voters. Four Democrats joined all Republicans to pass the measure in a 220-208 vote.

The House of Representatives passed the SAVE Act Thursday, with nearly all of the support coming from Republicans. While 208 Democrats voted against the measure, four Democrats joined the GOP in sending it to the Senate.

A bill that would require people to show documentary proof of U.S. citizenship to register to vote passed the House with some Democratic support.
