 From ABC News, I'm Dave Packer. President Biden vowing to return to the campaign trail next week. ABC's Selena Wang tells us some Democrats are hoping someone else will soon be on that trail. As President Biden pledges to fight on, top leaders in his party already looking ahead to what could come next if he drops out. Sources tell me the president is angry that leaders of his own party are turning against him. Now more than three dozen Democrats in Congress are calling on Biden to drop out of the race.
