“Today I heard some obfuscating of facts” from Clinton, Dawson said.

At the mention of the former secretary of State, the crowd began to boo.

“No, no, no, we’re better than that,” Dawson said.

Dawson went on to slam Clinton for implying that Sanders didn’t care about women’s issues because of his response to Donald TrumpDonald John TrumpJulián Castro: It's time for House Democrats to 'do something' about Trump Warren: Congress is 'complicit' with Trump 'by failing to act' Sanders to join teachers, auto workers striking in Midwest MORE’s suggestion that women should be punished for getting illegal abortions. He called the proposal, which Trump later reversed, "shameful."

“Shame on you, Hillary,” Dawson said.

“Oh sorry hold on, let me watch my tone. Because we very much want a debate, which she already agreed to,” she said, referring to Clinton adviser's comment that she would debate Sanders only if he “changed his tone.”

“I don’t have to vote against someone; I can vote for someone who’s on our side,” she added.

The feud between Sanders and Clinton has escalated in recent days. Another celebrity Sanders supporter, Susan Sarandon, said she didn’t know whether she would support Clinton in a general election against Trump.
