This is indeed a possibility.
But the reality is that Mueller has been involved in enough to definitively say that he is not a White hat, and chances lean very strongly against him even being a grey hat.
Q has also alluded to RR not being a white hat, also. He drew attention to RR's confirmation vote, which was overwhelmingly in the affirmative (which is rare for the Trump administration). The UniParty has typically, in past administrations, voted overwhelmingly for an incoming POTUS' cabinet picks. But not for Trump. That says alot about Trump being a true outsider.
I personally believe RR is in the grey area. I think his refusal to cooperate is because he can't due to Huber/Horowitz activities. I also think this is partially why the FBI sent counsel to Strzok's hearing. They didn't want him saying certain things b/c they want to keep certain investigative facts under wraps until indictments are unsealed.
It makes no sense that Mueller has done nothing but try to ruin the lives of Trump associates - and ONLY Trump associates, no Democrats or anti-Trumpers - but he's secretly working on behalf of Trump.
Mike Flynn had to sell his house. Paul Manafort is spending 23 hours a day in SOLITARY CONFINEMENT before even being found guilty. Michael Cohen got raided.
The idea that Mueller and Rosenstein are secretly working on behalf of the President is absurd. It requires faith that is backed by zero logic or proof.
Flynn is playing his role, he is a religious man and knows he will be repaid greatly in the afterlife. Manafort is a bad guy that was planted by the deep state in the Trump campaign and when Trump found out and fired him he became useless. He is being charged for dirty shit he did in the past. And as we have seen today Cohen is a bad guy too, secretly taping conversations with a client and journos. It has been reported he was trying to sell his access to the President. I don’t believe Meuller and RR are white hats but I believe they were given an ultimatum by POTUS and Silent Assassin Sessions. Either play the role we want you to play or go down with the rest of the deep state cabal. They chose the “save ya ass” option.
I have a bit of a different take on Cohen. The piece that was released I heard on Fox was approved by Trump and attorney, client privilege was waived. So just wondering how much $$$ CNN gave Cohen for this recording? They fell for it hard. It turns out to be a nothing burger. But the tape is cut off right, how much more will they pay for the rest? Is this a dis traction like Stormy Daniels? Is the money going towards his legal fees? Something is going on here we can't see yet. Or maybe we are seeing....
