ROUGH CUT (NO REPORTER NARRATION). STORY: Vermont Senator Bernie Sanders told CBS's Face the Nation that while he has been urging his supporters to support Democratic nominee Hillary Clinton, not all will end up backing Clinton in November. "We have over 13 million people who supported my candidacy. And I have no doubt that there are some of those people who will not vote for Hillary Clinton," Sanders said. "But I would say that the vast majority of them -- and I think as the campaign progresses and people take a hard look at the issues... I think more and more of those people will come on board Secretary Clinton's campaign."
