Democratic presidential candidate Sen. Bernie Sanders of Vermont said during a rally in Philadelphia that his rival, Hillary Clinton, is not qualified to be president.
"Secretary Clinton appears to be getting a little bit nervous," he said on April 7, CNN reported.
"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."
In response to Sanders' comment, Clinton campaign spokesman Brian Fallon tweeted that it was a "new low" to accuse her of being unqualified, and that the former secretary of state "did not say Bernie Sanders was 'not qualified.'"
Clinton was reportedly asked whether or not she felt Sanders was "ready to be president."
"I think he hadn't done his homework and he'd been talking for more than a year about doing things that he obviously hadn't really studied or understood, and that does raise a lot of questions," she said. "Really what that goes to is for voters to ask themselves can he deliver what he's talking about."
Clinton has recently been citing a New York Daily News interview with Sanders as proof of his lack of qualification for the presidency -- which Sanders addressed at his Philadelphia rally.
"I don't think you are qualified if you have voted for the disastrous war in Iraq. I don't think you are qualified if you have supported virtually every disastrous trade agreement which has cost us millions of decent paying jobs," he said.
"I don't think you are qualified if you've supported the Panama free trade agreement, something I very strongly opposed and, which as all of you know, has allowed corporations and wealthy all over the world people to avoid paying their taxes to their countries."
After Sanders' win in Wisconsin on April 5, Clinton dismissed the win and insisted that she still held a national lead against the senator.
"I think that Sen. Sanders had a good night last night, and I congratulated him," she told CNN"s Chris Cuomo, USA Today reported. "But if you look at the numbers, I’m still considerably ahead in both the popular vote and most importantly the delegate count. So I’m feeling very good about where we are."
