Sanders feeling media heat after new interview

Bernie Sanders' interview with the New York Daily News ahead of the state's primary later this month didn't go as planned.

The Vermont senator's April 1 sit down with the paper's editorial board, a transcript of which was published Monday, showed him having difficulty clearly answering some questions about both foreign and domestic policy, including the implementation of his much-touted plan to reform Wall Street.

Several times during the interview, Sanders expressed uncertainty over facts, said he couldn't give a proper answer to a question because he didn't have all the relevant information, or simply stated, "I don't know."

In one exchange, Sanders acknowledged that he wasn't sure exactly how he intended to break up the big banks, a proposal that has been a centerpiece of his Wall Street reform agenda.

"I think the interview raised a lot of really serious questions," Hillary Clinton said Wednesday on MSNBC's "Morning Joe." "I look at it this way, the core of his campaign has been break up the banks and it didn't seem in his answers he understood how that would work under Dodd Frank."

Clinton continued, "I'd think he hadn't done his homework and he has been talking for more than a year about ... things that he obviously hadn't really studied or understood and that does raise a lot of questions and really what it does is for voters to ask themselves, can he deliver what he is talking about, can he really help people."

For some political observers, the senator's difficulty in providing direct answers to some questions reinforced their belief that he lacks a concrete plan to implement his domestic agenda and is ill-prepared to handle the global challenges he would face as president.

"If Hillary [Clinton] gave answers like this to [an editorial] board, she would be crucified," tweeted Mark Halperin, the Bloomberg television host and co-author of "Game Change."
