Joe Biden has won the US Presidential election.
He's projected to have taken the state of Pennsylvania - giving him enough electoral college votes to become the next President of the White House.
The Democrat's tweeted he's honoured to have been chosen to lead the US.
But Donald Trump's vowed to launch legal action in a number of states, repeatedly making unsubstantiated claims of voter fraud.
Mr Biden, at 77, is the oldest candidate ever elected to the White House.
The President-Elect has Mayo roots dating back to his great-great-great grandfather Edward Blewitt, who was born in the Ballina area.
