President Biden is now being “receptive” behind closed doors about the possibility of giving up his 2024 re-election campaign, according to a senior Democratic adviser.

The 81-year-old president, who tested positive for COVID-19 Wednesday, has so far been adamant that he will remain in the race for the White House — despite repeated calls from Democrats for him to step aside in the wake of his train wreck debate three weeks ago.

“He’s being receptive. Not as defiant as he is publicly,” one senior Democratic adviser told CNN late Wednesday.

“He’s gone from saying, ‘Kamala can’t win,’ to ‘Do you think Kamala can win?” the adviser continued. “It’s still unclear where he’s going to land but seems to be listening.”

The official added that Biden’s conversations about his future are sill continuing in private with those on the Hill.

The Biden campaign, however, dismissed the claim he was rethinking his presidency.

“If the facts matter – and they should – here is one: President Biden is the Democratic nominee and he is going to win this November,” a Biden spokesman, Kevin Munoz, said.
