Democrat Joe Biden on Monday won the state-by-state Electoral College vote that formally determines the US presidency, all but ending President Donald Trump’s floundering campaign to overturn his loss in the Nov. 3 election.

Iran PressAmerica: California, the most populous state, delivered its 55 electoral votes to Biden on Monday afternoon, officially putting the former vice president over the 270 votes needed to secure the White House.

Based on November’s results, Biden earned 306 Electoral College votes to the Republican Trump’s 232, Reuters reported.

Earlier in the day, electors in several major battleground states where Trump has unsuccessfully sought to reverse the outcome - Arizona, Georgia, Michigan, Nevada, Pennsylvania, and Wisconsin - also voted for Biden, who is set to take office on Jan. 20 alongside running mate Kamala Harris.

Traditionally a formality, the Electoral College vote - set for Monday by federal law - assumed outsized significance because of Trump’s unsubstantiated claims of widespread fraud.
