In a particularly striking moment, host Aimee Allison asked Sanders what he would do to fight white-supremacist violence. In response, Sanders launched into a familiar anecdote that — perhaps precisely because of its familiarity — seemed to crash and burn.

“I know I date myself a little bit here, but I actually was at the March on Washington with Dr. [Martin Luther] King back in 1963,” Sanders began, as audible groans and jeers broke out at the auditorium at Texas Southern University. One person apparently shouted, “We know!”…

Separately, co-host Joy Reid asked Sanders how he would win over Hillary Clinton voters, including black women in particular. In response, Sanders trashed Trump as “the most dangerous president” in modern history, and generally called for unity among Democrats as well as “social justice, racial justice, and environmental justice.”

That response immediately drew more hecklers, as Reid pressed, “Yeah, and for black women specifically?”
