I don't know why some anons still cannot figure it out.

Nunes is correct, Mueller knew. And that's why RR said Trump is not a target in the Mueller investigation.
So the investigation went elsewhere with an expanded scope.
Manafort, Flynn and Cohen all needed guilty pleas so prosecution can see all evidence. Flynn has a story to Tell. Manafort leads to Skippy. And Cohen knows everything Trump knows having been his lawyer for a decade.
