California, the most populous state in the US, delivered its 55 electoral votes to Mr. Biden on Monday afternoon, officially taking him over the 270 votes needed to secure the White House.
When all of the states finish voting, Mr. Biden is expected to lead Mr. Trump 306-232 despite the outgoing president still refusing to accept the outcome, falsely insisting that he won the election. On Sunday, the president tweeted: “Votes cannot be certified. This election is under protest!”
The Congress will meet on January 6 to certify the electoral college votes.
President-elect Biden and Vice President-elect Kamala Harris are due to be sworn in at noon on January 20, 2021
