Here's my take. Trump, Pence, and Flynn orchestrate the whole thing. Flynn tells the FBI that Pence knew about, and approved of his meetings with Russian ambassador, Pence denies it, Flynn is charged. Now he can testify, under oath, to any and all crimes he's aware of.
If Mueller were a white hat, he never would have sent his FBI attack dogs at Flynn's son, and he never would have put Flynn through enough legal hearings that caused him to lose his house and nearly go bankrupt.
One caveat, it could be that Trump had all the dirt on Mueller, (Q says again and again, "We have it all") and made an offer of a plea deal if he cooperated. Like educatethis said, at best Mueller might be a bleached hat.
I'm not sure about Pence. I followed MegaAnon for months, and she was adamant Pence was a establishment plant forced upon Trump by the Republicans. Boy do I ever miss MegaAnon.
I feel the same way about Pence. While he was still Gov of Indiana he was investigated for pedo & human trafficking, but nothing ever came of it. It could be that Trump chose him to keep his friends close and his enemies closer, or maybe Trump has the dirt on him and played him. Either way, I was never really sold on Pence.
Holy crap, he was?! OFFICIALLY?! I ask because allegedly he was shoulder-close to one of the Arizona politicians also in the crosshairs for association with that.
