 ABC News. I'm Sherry Preston. Sources tell ABC some of the highest ranking Democrats in Washington continue pressing President Biden to withdraw from his reelection bid. They include the Democratic leaders in both the House and the Senate and the Democratic donors who have contributed a lot of money. I'm told that in terms of the major donors, it has stopped. The money into the campaign has stopped. In polling, you've seen upwards of 70 percent of Democratic voters saying that they would like to see a different nominee. That is very hard to sustain.
