The House of Representatives is set to vote and likely to pass a sweeping election reform bill, HR-1, as soon as this week. Biden's fellow Democrats have a majority in the House, but the bill is unlikely to pass the Senate, where the measure would need support from all 50 members of that party caucus, plus 10 Republicans.
Republicans have said the law would take powers away from states and raise fraud concerns.
Democrats have been fighting to expand access to the polls through early voting, vote-by-mail and other measures, efforts that expanded as the coronavirus pandemic raged. Republicans have been fighting those efforts and pursuing measures to curb access to the polls. Former President Donald Trump, in his first public speech after his stinging Nov. 3 election loss to Biden, on Sunday proposed limiting absentee voting and days when Americans can vote.
Biden beat Trump by more than 7 million votes in the 2020 presidential election. Democrats enjoy an advantage over Republicans in voter party affiliation.
Trump never conceded the loss, and some of his supporters violently contested Congress' certification of Biden's win at the Capitol in a deadly Jan. 6 riot.
