Joe Biden is “absolutely” staying in the race for re-election in November and will return to the campaign trail next week, his team has said.

“He is absolutely in it,” Mr Biden’s campaign chairwoman, Jen O’Malley Dillon, told MSNBC in an interview, adding that he will return to the campaign trail next week after isolating from mild Covid symptoms.

Mr Biden has been facing calls from within his party to withdraw ahead of the election and let the party install someone with a better chance of beating Donald Trump.

In a note obtained by NBC News, one of Mr Biden’s campaign directors said he remained popular.

“While voters consistently mention President Biden’s age when contacted, our target voters - both re-engagement and true swing voters - are still planning to vote for him, making it clear the debate has not hurt support among the voters who will decide this election,” Dan Kanninen wrote in a memo.
