He said early on that he welcomed an investigation by the FBI. When asked why he didn't demand one, he was stating that it was up to the committee to decide how to investigate. I see him as an upset father and husband, whether he did it or not, he will be labeled with it forever. If you were accused of this, how composed would you be in a hearing if you had not done what was alleged? I'd be pretty upset too. So I don't think that is a deciding factor either way. I don't think he sounds guilty, but that doesn't mean he is innocent.
