Clinton Surrogate Ed Rendell Calls for Clinton to Tone Down the Negative Attacks

RENDELL: "He has every right to be there all the way through the last primary. Remember, Senator Clinton went to the last primary in South Dakota back in 2008, before she announced she was withdrawing. The thing that we would ask as Democrats, not even just Clinton supporters, we would ask Senator Sanders to do is tone down the negative attacks on Secretary Clinton and she should do the same."
