DES MOINES, Iowa -- Bernie Sanders said during the second Democratic debate on Saturday that he is sticking with his assessment from the first debate: He’s still sick and tired of Hillary Rodham Clinton’s e-mail.

In perhaps the most memorable line from the first face-off in Las Vegas, the Vermont senator turned to Clinton and said “the American people are sick and tired of hearing about your damn e-mails.”

Sanders’s declaration seemed to diminish the controversy over Clinton’s use of a private e-mail server while secretary of state. But some questioned whether Sanders was having second thoughts after The Wall Street Journal published an interview in which he said there are "valid questions" about Clinton's e-mails and that an FBI investigation should "proceed unimpeded."

During Saturday night’s debate, Sanders dismissed a suggestion that those remarks were inconsistent as “just media stuff.”

“I was sick and tired of Hillary Clinton's e-mail,” Sanders said. “I am still sick and tired of Hillary Clinton's e-mails.”

“What I would like for the media now is for us to be talking about why the middle class is disappearing, why we have more people in jail than any other country, why we have massive levels of income and wealth inequality, and we're the only major country on earth without paid family and medical leave,” Sanders continued. “We've gotten off Hillary's e-mails. Good. Let's go to the major issues facing America.”

Asked for her response, Clinton said: “I agree completely. … I couldn’t have said it better myself.”
