Just before the interview aired, a fourth Democratic House member – Rep. Mike Quigley of Illinois – called on him to leave the race to give the party time to nominate someone else. In the Senate, John Warner of Virginia is reportedly trying to assemble a group of Democratic senators to ask Biden to drop out, according to The Washington Post.

Biden hit back at those calling for him to step aside during Friday's ABC interview, commenting: "I'm not letting one 90-minute debate wipe out three and a half years of work. I'm staying in the race, and I will beat Donald Trump ."
