Actress Susan Sarandon on Thursday tore into the Democratic National Committee (DNC), calling it "completely corrupt."

“After my experience in the primary, it’s very clear to me the DNC is gone,” she told CNN's Carol Costello.

“Every superdelegate is a lobbyist. The way that the system is set up in terms of trying of having superdelegates — you could win a state and not get the delegates. It’s crazy.”

"Look, Bernie has said ‘don’t ever listen to me if I tell you how to vote,' " she said.

“What [Sanders] did is show people that they counted. He brought them hope. He’s supporting a lot of candidates. It’s very important to go and vote down the ticket.”

"I think we’ve been voting the lesser of two evils for too long. The good news is everybody’s so frustrated that at least we’re awake.”

Sarandon on Monday endorsed Green Party nominee Jill Stein.

“It’s clear a third-party is necessary and viable at this time,” she said in a letter posted on Stein’s campaign website. "And this is the first step in accomplishing that end.”

Stein has about 2 percent support nationally, according to a RealClearPolitics average of polls.
