this. Mueller was given the position, so he would expose himself as a crook and take everyone like Comey and Hillary down with him. Hook, line and sinker.

If you can't come up with proof you have to fake evidence to save your own ass and credibility. But once you do that you're just digging a deeper and deeper grave.
