This isn't true at all. Collision was rampant. Robert Mueller, a life long republican, decided it didn't rise to the level of criminal conspiracy. Surprise surprise.
Heavens, Crepitus... Mueller said no such thing. He never determined whether or not there was a conspiracy (to defraud the U.S. of A.). He said, he could not prove a conspiracy beyond reasonable doubt, and he also gave what were the causes of that failure, namely, deleted and encrypted communication, and overall lack of cooperation with the inquiry. That, to me, reads like, "Yeah, of course there was a conspiracy, but because of rampant obstruction and tampering with evidence, there is no proof to be had." Which is not exactly, but pretty close to, the opposite of what you falsely claimed Mueller said.
