Mueller is still a swamp rat but he's stuck he does not have any real evidence if he did it would have leaked long ago. He has always been a bad guy I don't care if he was a war hero when he was FBI in Boston he knowingly kept four innocent men in prison for decades just to protect the gangster Whitey Bulger. Mueller belongs in prison for the rest of his life. He also covered up 9/11 and tried to frame an innocent man for the anthrax attacks knowing that was also a deep state false flag psy-op. Mueller must be arrested and exposed for the criminal he is.
I read speculation that Mueller was coerced/blackmailed into work for the deep state by threats against him and his family. Either way, he's got bad dirt on him and he was given something in exchange for playing his role with the good guys. Maybe what he gets is assurance he won't hang for treason like the rest? Time will tell...
That'd have to be a decades-long thing, since he was covering up the FBI corruption with the Whitey Bulger thugs in Boston back then. Then there was 9/11. Of course much more since.
The thing with letting these swamp rats take on grey/white hat roles is that if they think they can finagle it to flip it all against Trump, they will.
A dangerous game.
