Actress Susan Sarandon Campaigns for Sanders in Iowa

She introduced him to a massive crowd in northern Iowa Wednesday.

“Gender is not what’s important,” she said. “Issues are what's important. I want a candidate who has the courage to stand to do the right thing when it is not popular.”

“That is not pragmatic, that's just cynicism. That's giving up before you’ve even tried,” she said.

Later in the evening, the Democratic presidential hopeful blasted Clinton even more directly.

“I am delighted to be here with you tonight in Mason City,” he said. “My opponent is not in Iowa tonight, she is raising money from a Philadelphia investment firm. Frankly, I would rather be here with you.”

Clinton left the state earlier Wednesday to attend a fundraiser that was hosted by executives of Franklin Square Capital Partners investing firm in Philadelphia. In response to Sanders’ criticism, the Clinton campaign pointed out that she also met with African-American ministers in the city, prior to her fundraiser.

The former secretary of state has one more fundraiser scheduled tomorrow morning in New York City before she returns to Iowa for campaign events in the afternoon.
