US Presidential: Biden calls for unity as his lead grows

Democrat Joe Biden has urged for unity in a brief address at his campaign headquarters in Delaware on Friday evening.

The former vice president took to the stage three nights after Election Day to again say his prospects for taking the White House look good.

"We don't have a final declaration of victory yet, but the numbers tell us it's clear," Biden said. "We are going to win this race."

No outlet has projected the election winner, but Biden leads in four critical battleground states yet to be called: Georgia, Nevada, Arizona and Pennsylvania. His lead has narrowed in Arizona Friday, but only grown in the other three. He leads by more than 20,000 votes in Nevada, Arizona and Pennsylvania.

Biden didn't step to the podium until nearly 11 p.m. Eastern time. Vice presidential nominee Kamala Harris joined Biden on stage, bt did not give remarks as previously planned if the race had been called. The former vice president spoke from the stage in Wilmington that had been constructed for a possible victory speech on election night.
