Washington (CNN)Bernie Sanders said Wednesday that Hillary Clinton is not "qualified" to be president, a sharp escalation in rhetoric in the Democratic primary.
"Secretary Clinton appears to be getting a little bit nervous," he told a crowd in Philadelphia. "And she has been saying lately that she thinks that I am 'not qualified' to be president. Well, let me, let me just say in response to Secretary Clinton: I don't believe that she is qualified, 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."
CNN has reached out to the Clinton campaign for comment, and its surrogates responded quickly on Twitter.
