When it comes to racism, most white people have the same visceral reaction: “I’m not a racist.” But Dr. Robin DiAngelo argues that’s not true.

In a stunning rebuke of the elected commander in chief, several generals – from James Mattis to John Kelly – have taken a stance against the president's handling of this crisis.

He joins the show from his home state.
