Bernie Sanders On The Attack Ahead Of Clinton Rally

One day before she holds her first major campaign rally, Democratic challenger Sen. Bernie Sanders criticized Hillary Clinton, indicating that he won't play nice against the front runner.

"I don't have a super PAC. I'm not going to be getting huge sums of money from millionaires and billionaires," Sanders said on MSNBC's "Andrea Mitchell Reports" when asked what the difference is between him and Clinton. "We have received well over 100,000 donations from individuals who have gone to And you know what our average donation is? It’s $40 apiece. So, working families all over this country are saying, Bernie, we want to stand with you, take on this billionaire class who are dominating our economics and our politics.”

While Clinton has a super PAC, which is able to accept unlimited campaign contributions from donors, unions and businesses, Clinton has said that one of the pillars of her campaign is to alter campaign finance rules to rein in the role of money in politics.

She announced her candidacy for the Democratic nomination in April but has kept a relatively low profile since then, holding small events in early primary states of Iowa, New Hampshire, Nevada and South Carolina while keeping her distance from the press.

Sanders, meanwhile, said he answers reporters questions "every day."

"It is hard for me to understand how you can run for president of the United States and not take questions," Sanders said.

Sanders declined to say if there's a conflict of interest between donors and the Clinton Family Foundation and Clinton's role as Secretary of State, saying he "has concerns" but that those questions are for Clinton to answer.
