President Joe Biden is facing an uprising from some his own party’s wealthy donors, including an heiress to the Disney family fortune, who say they will no longer fund the Democratic Party until Biden drops out of the presidential race following his disastrous debate performance.

Abigail Disney, granddaughter of Roy O. Disney, who co-founded The Walt Disney Co., told CNBC on Thursday that she plans to withhold donations to the party she has funded for years until Biden drops out. The president has said he has no plans to withdraw from the race, despite calls for him to do so.

“I intend to stop any contributions to the party unless and until they replace Biden at the top of the ticket.  This is realism, not disrespect. Biden is a good man and has served his country admirably, but the stakes are far too high,” Abigail Disney said in a lengthy statement to CNBC. “If Biden does not step down the Democrats will lose. Of that I am absolutely certain. The consequences for the loss will be genuinely dire.”
