 From ABC News, I'm Chuck Severson. At least four senior House Democrats called on President Biden to quit his campaign on a private call this afternoon with House Minority Leader Hakeem Jeffries. That's according to several sources with knowledge of the discussion on the call. They tell ABC News the reps were Jerry Nadler, Mark Takano, Joe Morrell and Adam Smith. Jeffries did not express a position, according to one person on the call who added there'll be talks this week.
