 President Biden, still recovering from COVID at his home in Delaware, signaled he'll return to the campaign trail next week. But calls continue to grow for him to step aside as the nominee. ABC's Selena Wang is in Rehoboth Beach. Yesterday, Vice President Harris joined a call with some of the campaign's biggest donors, but I'm told that this did not go well. A source who was on the call tells me that some donors were furious because they want President Biden to drop out of this race and feel like they didn't get a chance to share their concerns.
