absent actual Russian collusion then no. Remember, Mueller was brought in to find RUSSIAN COLLUSION. As of yet, I don't believe he has found any. If he had, I am 100% confident that there would have been a leak. There have been none
All he has found is Manafort was guilty of not registering as a foreign agent years before he was involved with Trump and Flynn "lied to the FBI", which probably isn't hard to get given the FBI had all of Flynn's phone calls going in. Sort of an unfair advantage if you ask me
