Oscar-winning actress and activist Susan Sarandon appeared to take a shot at Sen. Elizabeth Warren on Monday during a Bernie Sanders 2020 campaign event in Iowa.

“He is not someone who used to be a Republican,” Sarandon told the crowd during her introduction of Sanders, according to Politico reporter Holly Otterbein.

Sarandon, a Sanders supporter, didn’t mention Warren by name, but the Massachusetts senator was a registered Republican in the mid-1990s.

“I was a Republican because I thought that those were the people who best supported markets,” Warren told Politico in 2011. “I think that is not true anymore.”

Warren and Sanders — two liberal favorites — have been polling toward the top of the crowded Democratic presidential primary field.

One national poll released last week by The Economist/YouGov showed Warren coming in at second with 20%, while Sanders was close behind at 16%. Former Vice President Joe Biden topped that poll with 21% support.
