The U.S. House has passed a bill that voting rights groups have repeatedly warned would make it harder for millions of Americans, including married women, to vote.

The Republican-controlled House on Thursday voted for the Safeguard American Voter Eligibility (SAVE) Act. The legislation purportedly aims to block non-citizens from voting, which is already illegal and is very rare.

The bill would require an individual to present in person a passport, birth certificate or other citizenship document when registering to vote or updating their voter registration information.

Voting rights groups have said the bill will pose a barrier for millions of American women and others who have changed their legal name because of marriage, assimilation or to better align with their gender identity. An estimated 69 million American women and 4 million men do not have a birth certificate that matches their current legal name.

Republicans who support the bill claim that states will be able to create processes so people can prove their citizenship if their name doesn’t match their birth certificate. 

Voting rights groups also worry the bill will disenfranchise others from marginalized communities who are less likely to have the necessary documentation on hand. More than 9 percent of citizens of voting age — or 21.3 million people — do not have documents that prove their citizenship readily available.

They also warn the bill, if it becomes law, would eliminate popular methods of voter registration, such as online, mail and registration drives — adding demands on a women-led election workforce that has faced burnout and harassment after years of disinformation about election integrity. 

The House also passed the SAVE Act last year, but it died in the Senate. It’s now headed back to upper chamber, where Republicans have a 53-seat majority and the legislation needs 60 votes to pass.
