Senate Majority Leader Mitch McConnell (R-KY) congratulated Joe Biden on Tuesday as the president-elect, saying the Electoral College "has spoken."
McConnell's speech on the Senate floor follows electors voting on Monday night to certify a Biden victory. McConnell has been joined by other lawmakers, who are now saying that Biden won the presidential race.
"At some point you have to face the music," said Sen. John Thune (R-SD) "Once the Electoral College settles the issue today, it's time for everybody to move on."
Sen. Roy Blunt (R-MO) said the inaugural committee will now deal with Biden "as the president-elect," a reversal of its previous refusal to do so publicly.
Other top Republican lawmakers have said they will stand by President Trump's legal bid to overturn the election results.
"It's a very, very narrow path for the president," said Sen. Lindsey Graham (R-SC). "But having said that, I think we'll let those legal challenges play out."
