Donald Trump was at his golf course in Sterling, Virginia, when the news came in that Democratic Party's Joe Biden won the presidency.
Trump left the White House earlier today.
It's from there that he's thought to have issued his statement regarding the result, which followed new numbers released from the key state of Pennsylvania.
However, he tweeted saying, "I WON THIS ELECTION, BY A LOT!", one hour ago.
Meanwhile, Donald Trump has refused to accept defeat, saying, "This election is far from over".
In a statement, Trump said his campaign would begin challenging US election results in court next week.
"We all know why Joe Biden is rushing to falsely pose as the winner, and why his media allies are trying so hard to help him: they don't want the truth to be exposed," he said in the statement. "The simple fact is this election is far from over."
