 Sources tell ABC News that privately at least four top House Democrats told colleagues on a call Sunday it's time for Biden to end his campaign. Congressman Jerry Nadler, Mark Takano, Joe Morrell and Adam Smith joining five other Democrats who've made the same plea publicly. But sources say minority leader Hakeem Jeffries, who convened Sunday's call, did not take a stance. With lawmakers back on the Hill this week, the coming days will be critical.
