Robert Reich Still Sees No 'Convincing Explanation' on Hillary Clinton Email

Ex-labor secretary ties issue to Clinton's poll numbers.

RR: I've known Hillary Clinton since she was 19, and have a great deal of confidence in her. At the same time, I agree with Bernie Sanders on much of what he says. But as chairman of Common Cause, a nonpartisan national citizen's group dedicated to getting big money out of politics, I don't feel free to endorse either one of them.

2. Bernie Sanders said he would consider you for treasury secretary during an interview with George Stephanopoulos on “This Week.” Would you serve in his administration if he got elected and asked you?

RR: Sure.

4. The number of people, according to a new ABC News-Washington Post poll, who see Hillary Clinton as trustworthy has dropped in recent months. Why do you think this is?

RR: She hasn't yet given a convincing explanation for why she used a private email account when she was secretary of state, and why she and her husband have made so many speeches for hundreds of thousands of dollars a pop from special interests that presumably want something in return. In other words, she needs to be more open and transparent about everything.

5. OK, prediction time. Who do you think will be the presidential nominees for both the Republicans and Democrats?
