Just wanted to remind any Anons that forgot: this mirrors what FBIanon said. Mueller was used, and forced into the swamp. Blackmailed. As a result he ended up knowing many of the Cabal's secrets, and the Cabal thought he was one of their Blackhats.
Except he wanted out, and was given the opportunity to make up for his wrongdoing by double crossing the Cabal, and leading them into a false sense of security with his appointment.
Other aspects of FBIanon dovetail with Q.
If this ends up being the truth many heads will explode.
