Bernie Sanders is kickin’ it up a notch.

During a speech to a raucous crowd in Philadelphia Wednesday night, Sanders declared Hillary Clinton is “not qualified” to be president because of the funds she takes from special interest groups.

MSNBC rushed to air the footage before Sanders’ speech was even over.

“She has been saying lately,” Sanders told a packed basketball area, “that she thinks that I am ‘not qualified’ to be president,” eliciting sustained boos from the audience.

“Well, let me just say, in response to Secretary Clinton, I don’t believe that she is qualified if she is…” he said, before being met with wild cheers. “If she is through her Super PAC taking tens of millions of dollars in special interest funds.

“I don’t think that you are ‘qualified’ if you get $15 million from Wall Street through your Super PAC. I don’t think you are ‘qualified’ if you voted for the disastrous war in Iraq.”

Host Rachel Maddow observed before airing the statement that Sanders was going after Clinton “in a way we’ve not heard before.”

“This is what you call a tipping point. This is when the Democratic presidential primary process suddenly becomes a very different contest with a very different aim from the way it started out,” Maddow said.
