Clinton Cries Foul over Sanders TV Ad on Wall Street

Hillary Clinton and Bernie Sanders are at odds over a new ad by the Sanders campaign that suggests Clinton wouldn't be tough enough on Wall Street.

Clinton's campaign said Sanders is breaking his pledge not to run negative advertising.

Sanders' presidential campaign released an ad in Iowa and New Hampshire Thursday in which Sanders tells viewers there are "two Democratic visions for regulating Wall Street."

Sanders says one vision sees it as "OK to take millions from big banks and then tell them what to do." He says another would break up big banks, close tax loopholes and make Wall Street pay its 'fair share'."

Clinton's campaign says it's surprised by the ad. Clinton strategist Joel Benenson says Sanders is "doing something that he proudly said he would never do."
