A clearly flustered Joe Biden called the president and clown and told him to 'shup up' as Trump attacked Biden's record, his son, his party, and threw more lies at the Democratic nominee than fact-checkers could count running roughshod over debate moderator Chris Wallace. Trump also refused to denounce white supremacists during the debate. We discuss it with Biden's running mate Kamala Harris, plus Claire McCaskill, Lawrence O'Donnell, Eugene Robinson, James Carville, David Plouffe, Mike Murphy, Dr. Vin Gupta, Biden aide Symone Sanders, Robert Gibbs, Robert Costa, Alicia Menendez, Susan Glasser, and Peter Baker.
