More important contributors are threatening to withdraw their support for the Democrats if Joe Biden is not replaced as the party's candidate before the presidential election in November.
If Biden doesn't step aside, the Democrats will lose, says Abigail Disney, heiress to the Disney fortune, who has donated large sums to the party.
The granddaughter of Roy O Disney, co-founder of the Disney empire, doesn't mince words when announcing her decision to no longer support the Democrats.
This is realism, not disrespect. Biden is a good man who has served his country admirably, but the stakes are too high, says Abigail Disney to CNBC.
Stops all contributions
She adds that she is "absolutely certain" that the Democrats will lose if Biden is not replaced as the party's presidential candidate before the autumn election, and mentions Vice President Kamala Harris as a possible replacement.
I will stop all contributions to the party until they replace Biden.
Entrepreneur and philanthropist Gideon Stein also announces that he is pausing planned contributions of $3.5 million that were to go to non-profit and political organizations before the presidential election.
Biden: Going nowhere
The pressure on Biden has increased after his disastrous debate performance against Trump last week. Some question whether Biden has the strength required for another four years in the White House, while others support him and argue that it was just a bad night.
I'm going nowhere, said Biden himself at a barbecue during American Independence Day celebrations on Thursday evening.
Sources tell American media that Biden, in a meeting with Democratic governors on Wednesday evening, is said to have admitted that he needs to get more sleep and would benefit from limiting activities after 8 pm.
He did it with a smile on his lips. It was more of a rhetorical device to appear fit and rested, says California Governor Gavin Newsom, who attended the meeting.
"Had a bad night"
Newsom, who has rallied behind Biden after the criticized debate performance earlier in the week, added:
I like when presidents acknowledge that they are human beings.
In an interview with a local radio station in Philadelphia, Biden admitted that he "had a bad night" and messed up in the debate.
But 90 minutes on stage doesn't erase what I've done over three and a half years, he said in the interview, which was recorded on Wednesday.
