Joe Biden is projected to win the state of Georgia, as media reports say Donald Trump is considering running again in 2024.
President-elect Biden picked up a further 16 Electoral College votes with his expected Georgia win, taking his final tally to 306 votes.
The state has not voted for a Democrat in almost 30 years, although it is subject to a ballot recount as the margins between the two candidates were so close.
Democratic Party lawyer Marc Elias has said he is confident the recount will not change the results of the election in Georgia.
In another blow to the president, the Washington Post has reported more than 130 Secret Service officers assigned to protect Mr Trump are self-isolating due to coronavirus. It is not clear how many have tested positive.
Meanwhile, Mr Trump is projected to win North Carolina – which he also won four years ago – taking his total to 232 votes.
Commentators have pointed out that a similar number of votes were won by each candidate in the 2016 presidential run-off between Mr Trump and Hillary Clinton – although they were flipped around, giving the Republican the win.
The president is yet to concede the election, despite numerous news networks declaring Mr Biden the winner, and several Republican candidates have followed his lead in refusing to concede.
However, Mr Trump could end up conceding before announcing he will run again at the next election.
Conservative commentator Eric Bolling, who has been friends with the president for 20 years, said he believes a concession is “probably imminent”.
He expects Mr Trump will wait until after a large Republican march in Washington DC on Saturday.
“He’s clearly not going to disappoint those people – he’s going to wait until after that at least. But then announce a 2024 run,” he said.
The president has repeatedly claimed, without evidence, there has been widespread election fraud that hurt his chances of being re-elected and in a tweet, on Friday he said the vote was “rigged”.
In an interview with the Washington Examiner, he said he believed he could turn the election in his favour within two or three weeks.
Mr Trump suggested the results of recounts in Wisconsin and Georgia could see him win them back – although Mr Biden has a sizeable lead in both states – and also claimed he could take back Michigan and Pennsylvania through challenging ballots in the courts.
Election officials have dismissed claims of fraud and two security groups have said there is no evidence that ballots were deleted or lost.
