Joe Biden is now projected to have 284 Electoral College votes, the Associated Press (AP) news agency said on Saturday, above the threshold needed to clinch the hard-fought United States presidential election.

The president-elect was projected to have surpassed the 270 electoral vote-threshold after the AP called Pennsylvania in his favour.

“I am honoured and humbled by the trust the American people have placed in me and in Vice President-elect [Kamala] Harris,” Biden said in a statement a few minutes after the projection was announced.

With Biden’s projected win, Harris will be heading to the White House as his vice-president, and is set to create new records along the way.

She has had a trailblazing career, and will now be the first African-American, first woman and first person of Asian descent to serve as vice president.

Meanwhile, Trump’s campaign has vowed to challenge the result, particularly in the states of Georgia, Pennsylvania, Arizona.
