Clinton sat down with Mitchell on Friday and the main topic from the start was her use of a private, unsecured server as secretary of state, which has caused serious problems for her campaign with questions about her honesty, trustworthiness and handling of classified material. While other presidential candidates have made dozens of media appearances, Clinton has given just three nationally televised interviews since her campaign began.

“We were told we had a 15-minute interview,” Mitchell said. “I asked more than 12 minutes on emails before I felt, out of concern that they would cut it off, obviously, that I had to move on, so I couldn’t ask everything that I did want to ask, but I think we did get a good chance to ask a lot of questions and discover that she did not have an answer for why she did the personal server in the first place.”

Clinton also twice refused to apologize for having a private server during the interview, and she said she “was not thinking a lot” when she made the decision to have a private email in the first place.
