Bernie Sanders apologizes for surrogate's op-ed criticizing Joe Biden
Senator Bernie Sanders apologized to Joe Biden for an op-ed written by one of his campaign surrogates. In the op-ed for The Guardian, Zephyr Teachout accused the former vice president of having what she called a "big corruption problem." Sanders told CBS News in an exclusive interview that those claims are "absolutely" not his view. CBS News campaign reporter Cara Korte joins CBSN to discuss the latest from the Sanders campaign.
