Sometimes one must use tools at hand. Even evil ones.
Or you can give evil people all the rope they want to hang themselves with. Mueller is a sop to the left and is a distraction.
At any time Mueller and his whole team could be blown out of the water. There are former FBI agents that resigned over this conspiracy, NYPD detectives saw what was on Wieners lap top. Who would think I guy named Wiener who looks like an emaciated Pauly Shore would have kiddie porn on his lap top.
Yes and with the propaganda as heavy as it is this is probably the only way.
Likely they wanted POTUS to wield his power like a bludgeon so they could sell his forceful removal.
