An intro speaker at a Bernie Sanders rally in New York City Wednesday evening said that if we keep electing "corporate Democratic whores" like Hillary Clinton, the U.S. will never had "Medicare-for-all."



Sen. Claire McCaskill responded on Thursday morning's Morning Joe, saying it is "unacceptable for anybody to reference Hillary Clinton as a corporate whore."



"And that's what happened at the introduction last night at that rally," she continued. "I have not yet heard Bernie Sanders say totally unacceptable, it is totally unacceptable."



"Think it is really important we keep the tone where it should be," she concluded.
