No one knows everything about any subject. I can only comment on what I see. What I see is a very weak Attorney General who is, apparently, refusing to investigate hundreds, if not thousands, of obvious felonies. If you know something different, please say so. (Apologies if you've already said so.)
Jason Chaffetz was telling the truth: history for Jeff began the day he was confirmed and don’t expect any action on crimes before that date.
