Six more congressional Democrats, among them a senator, called on President Joe Biden to exit the election contest Friday even as Biden's campaign chair brushed those calls aside, saying "Absolutely the president's in this race." Despite that vow by campaign chief Jen O'Malley Dillon, two people familiar with the situation told NBC News that members of Biden's family have discussed what his exit from the election race against the Republican presidential nominee Donald Trump would look like, if he makes that decision. So far, 25 House Democrats and three Democratic senators have urged Biden to drop out. Sen. Martin Henrich of New Mexico became the third Democratic senator to come out against Biden's continued candidacy, joining Jon Tester of Montana, who made his announcement Thursday, and Vermont's Peter Welch.
