So let's review. Manafort is facing trial for failing to register as a foreign lobbyist and for a tax crime from nearly a decade ago. Which of those two things support the Russians helping Trump? Any other folks tied to Trump that have been charged have been charged with process crimes, like lying to the FBI. None have been charged with any actual conspiracy type charges, because "collusion" isn't against the law.
The conflict is Mueller drug up Manafort's connections to Oleg from the past, yet none of the court documents show any disclosure about Mueller, McCabe, or Rosentstein's past covert, "back channel" work with Oleg.
