Defiant United States president, Joe Biden, has vowed to resume his presidential campaign next week, despite fellow democrats urging him to quit the race.

Speaking on MSNBC’s “Morning Joe,” on Friday, the chair of Mr Biden’s presidential campaign, Jen O’Malley Dillon, said “he’s in it to win it.”

Also, the president and his campaign advisers, in a statement, expressed his eagerness to resume his campaign to “continue exposing the threat of Donald Trump’s Project 2025 agenda while making the case for my own record.”

Close associates to Mr Biden and his team had reportedly expressed belief that he had been privately considering whether or not to contest the election against former president, Donald Trump.

According to them, Mr Biden, who is under isolation at his beach house in Delaware, after testing positive for COVID-19 on Wednesday, during a campaign swing in Nevada, is listening to calls for him to withdraw from the poll.

Mr Biden cut short his trip, following the illness, as he looked frail and tired upon his return to Delaware. But the White House physician in a letter on Friday, said that after being administered four doses of the antiviral drug Paxlovid, the President’s recovery has improved, with his pulse, blood pressure and other vitals back to normal.

Mr Biden’s associates were said to be empathetic that he would be humiliated if he was forced out of the campaign for the re-election that he hoped to win.

The President’s resolve to remain in the race may however change based on the decision by a former House speaker, Nancy Pelosi, to weigh in on his candidacy; state polls showing that his path to an Electoral College victory has reduced; and a spending boycott by major party donors.
