Except for this investigation, Huber reports to Rosenstein. The conflict is obvious.
When Huber was confirmed in August, Rosenstein made a special trip to the Utah office. Here's a pic of Rosenstein in Utah showing Huber who is boss.
This IS the investigation as noted by Sessions and he was the one that appointed Huber and he just said that Huber along with other federal prosecutors go directly to him....ie...Sessions. If Rosenstein did something and theres no doubt he did then they arent going to go to him, theyll go to Sessions. Look, I know theres a healthy distrust of FBI and DOJ but most of the trouble makers were senior leadership in D.C. but are still at least some peoplerank and file in there that see stuff and arent going to let everything disappear in a black hole. All of these leaks about obama administration corruption about Trump havent only been coming from Congressional Republicans
