President Joe Biden reportedly told a key ally that he has doubts about whether he can continue the campaign, but the White House has fiercely denied the account.

The unnamed key ally said Biden knows his next public appearances must go well, according to a report from the New York Times, and that he knows the position he is in after a disastrous debate performance last week in Atlanta. Biden has a public White House event on Tuesday, along with campaign events throughout the holiday weekend, and is scheduled to sit down with ABC News for an interview on Friday.
