Joe Biden officially passes 270-vote threshold to win Electoral College on California's vote

The Electoral College elected Joe Biden as the next president Monday, formalizing the former Democratic vice president's win in the Nov. 3 election as President Donald Trump continues a long-shot effort to try to overturn the outcome.

Around 5:30 p.m. EST, California's 55 electors cast their ballots to push Biden over the 270-vote threshold needed to win.

Biden and Sen. Kamala Harris, the vice president-elect, received 306 electoral votes overall, topping Trump’s 232 votes. Next, the electoral votes will be counted at a special joint session of Congress on Jan. 6 before Biden and Harris are inaugurated Jan. 20.
