"Late Show" host Stephen Colbert last night welcomed actress, activist and ardent Bernie Sanders supporter, Susan Sarandon.
Sarandon said she had to "break up" with Hillary Clinton -- the two, at one time, posed together for a photo, which she brought out last night.
"I told her don't go in Iraq. I'm very upset about that," Sarandon explained. "I said there's not enough evidence and there's no exit strategy, everything that everyone was saying. And she went in."
Sarandon continued to grill Clinton, who supports fracking, on her environmental record as Secretary of State.
"Fracking is absolutely the worst thing you could do for the environment," she said. "She goes behind my back and she's selling it all over the world."
Asked what makes her so "moon-eyed" over Bernie Sanders, Sarandon touted his consistency.
"He's been consistently morally in the right place my entire life," she said. "He's always there before it becomes simple. And you need somebody who has the moral judgement beforehand, not when it's safe."
