American actress Susan Sarandon took a veiled shot at 2020 Democrat Elizabeth Warren while campaigning for her opponent, Bernie Sanders.

Sarandon promoted independent Vermont Sen. Sanders at a Monday rally in Iowa, boasting that "he is not someone who used to be a Republican," according to Politico reporter Holly Otterbein. The award-winning actress did not make a direct comparison to any other 2020 Democratic presidential contenders.

“He is not someone who used to be a Republican,” says Susan Sarandon while introducing Bernie Sanders at an ice cream social in Iowa, talking about how he’s fought for the same issues for years.

The comment serves as a slam against Massachusetts Sen. Warren, who was a registered Republican for at least seven years until 1996, when she switched parties to be a Democrat.

Sarandon has earned notoriety among Democrats and is often accused of helping President Trump win in 2016. Sarandon opted not to support former Secretary of State Hillary Clinton in 2016 and voted third party instead.

Susan Sarandon is a proven enemy of the Democratic Party. She actively helped to elect Donald Trump. Accepting her endorsement or including her in a political rally should be unacceptable to any candidate whose true priority is to ensure Dem victory in 2020. https://t.co/Quev2cQYxl — David Rothkopf (@djrothkopf) August 19, 2019
