While the president's inner circle and campaign are adamant that he is just as committed as ever, the president has become more receptive to hearing out calls for him to exit the race, a senior administration official tells ABC News.

Biden has also asked for polling on how Kamala Harris would do, according to the official.

There is no indication that Biden is changing his mind.

When it comes to money, the big donors in New York and California have let the team know they are not saying no, but have hit the pause button for now, the official said.

The official noted that the president is wiped and exhausted, but the COVID-19 diagnosis gives him a chance to bring people together, have conversations and think while he recovers in Delaware.

As President Biden faces mounting calls from prominent Democrats to drop out of the race, a member of his inner circle flatly denied reports that the president is now more open to the idea of ending his campaign.

"Anyone who has talked to Joe Biden in the last 24 hours can tell you that is not true," the senior White House official, who has spoken to Biden today, told ABC News.

The official said nothing has changed regarding Biden's candidacy and the campaign, with the exception that COVID is keeping him home.

"He is going to win the nomination and then the party is going to need to unite," the official said.

The senior official expressed anger and frustration at the criticism Biden is taking from fellow Democrats, acknowledging that the calls for the president to drop out have taken a toll and will likely cause further erosion in the polls.

This official also told ABC News that reports to the contrary are coming out of Congress, and not from those who truly know the mindset of the president.

"He is preparing to hit the campaign trail again next week," the official said.

President Joe Biden in an interview with BET said he would be open to relinquishing the presidency during his second term if health reasons dictated it, though he dismissed the possibility as unlikely.

"Only if I was told that there was some medical condition that I had, and that's not the case," the president said when asked if he would turn over power to Vice President Kamala Harris if he couldn't complete a second term.

In the pre-taped interview, which aired in full Wednesday night, Biden told BET's Ed Gordon that he would keep serving as long as the effects of his increasing age don't impact his ability to do the job.

He also acknowledged he would be willing to evaluate his capabilities on a year-to-year basis.

Speaker Emerita Nancy Pelosi spoke with President Joe Biden a week ago, telling the president that she and other members of the Democratic Party are concerned about him staying in the race, a source confirms to ABC News.

Pelosi told the president that the calls for him to step down from the ticket would grow, sources said.

It is possible that Pelosi could suggest Biden should step down publicly, a source said.

The news about Pelosi’s behind-the-scenes moves comes as associate Rep. Adam Schiff, who is running for Senate, spoke out publicly earlier Wednesday, saying Biden should “pass the torch.”
