It does make sense that Mueller would be working on our side. The media obviously can't say "don't trust Mueller because he's not going after Trump, he's really helping Sessions go after crimes of the DNC." Crimes? what crimes? let's hear more.
So they have to say trust Mueller since he was hired to go after Trump. Then Mueller will pull through.
I just don't see how they stocked the team with dems and kept adding staff, with Mueller himself having a corrupt past, while genuinely helping MAGA, not leaking to the press, and so forth.
