When Director Rob Reiner appeared on MSNBC's Morning Joe Thursday to discuss his new film, "Being Charlie," the infamously liberal director couldn't stay away from politics. The conversation quickly turned to Donald Trump, and Reiner didn't hold back his true feelings.

Morning Joe co-anchor Willie Geist asked Reiner, "There are millions and millions of people who do not watch this show that actually like what they hear from Donald Trump. And they aren't taking messages and orders from us in the media. But they listen to what he says for themselves and vote for him. How do you explain that?"

"There are a lot of people who are racist," Reiner quickly replied.

Joe Scarborough was shocked, remarking, "Oh my God, did you just say that?"
