Biden now leads Donald Trump by 13,220 votes in Pennsylvania, but the AP has not yet declared a winner in the state. Biden is clearly intending to declare victory, with plans to deliver a primetime address tonight.

Georgia will hold a recount to settle the virtual tie between Biden and Trump in the state. As of now, Biden leads Trump by just 1,558 votes in the state, where about 5 million ballots were cast in the presidential race.

Biden’s lead in Nevada grew to 20,137 votes, following an update from Clark county, where Las Vegas is located. But the AP has not yet called that state either, and a Clark county official said today that counting would continue through the weekend.

Securing Pennsylvania’s 20 electoral votes would put Biden over the 270 he needs to win the presidency after a political career stretching back nearly five decades.

Biden would also win if he prevails in two of the three other key states where he was narrowly ahead on Friday: Georgia, Arizona and Nevada. Like Pennsylvania, all three were still processing ballots on Friday.

As Biden’s lead grew in Pennsylvania, hundreds of Democrats gathered outside Philadelphia’s downtown vote-counting site, wearing yellow shirts reading “Count Every Vote.” In Detroit, a crowd of Trump supporters, some armed, protested outside a counting location, waving flags and chanting, “Fight!”

Sources close to the White House said some senior officials inside the White House and the campaign are beginning to quietly back away from Trump, in acts of self-preservation, as the returns in Pennsylvania and Georgia indicate the President will not win reelection. 

"It's over," one key adviser to the administration said of the race. The adviser went on to say there are concerns about what Trump will do, beyond the question of whether he will concede the race.
