Hillary Clinton on Thursday morning brushed off a Wednesday night comment made by Sen. Bernie Sanders (I-VT) that the former secretary of state is not qualified to be president.

“It’s kind of a silly thing to say, but I’m going to trust the voters of New York, who know me, and have voted for me three times — twice for senate, once in the presidential primary,” Clinton told reporters outside of a campaign event at Yankee Stadium in New York. “I don’t know why he is saying that, but I will take Bernie Sanders over Donald Trump or Ted Cruz any time.”

“So, let’s keep our eye on what’s really at stake in this election. We have Republicans whose values are so antithetical to what’s right for New York or right for America,” she added.

During a campaign rally in Philadelphia on Wednesday, Sanders railed against Clinton’s campaign contributions, past vote for the Iraq war, and positions on trade deals.

“Secretary Clinton appears to be getting a little bit nervous,” he said. “And she has been saying lately that she thinks that I am quote unquote 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.”

He made the remarks in response to an interview Clinton gave to MSNBC on Wednesday morning, during which she criticized his answers to questions about breaking up big banks from the New York Daily News.

“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,” Clinton said when asked whether Sanders was qualified or ready to be president. “Really what that goes to is for voters to ask themselves can he deliver what he’s talking about.”
