Dem Rep. Mike Quigley calls on Biden to step aside: 'Let someone else do this'

Congressman Mike Quigley (D-IL) tells Chris Hayes that Joe Biden should exit the race: “Mr. President, your legacy is set. We owe you the greatest debt of gratitude. The only thing that you can do now to cement that for all time and prevent utter catastrophe is to step down and let someone else do this.”
