As others pointed out, Dumbass Junior already confessed to collusion.
But, to play your game, what would REALLY be funny is that if it turns out Dumbass Donnie Dump was actually oblivious to the whole thing (Very doubtful, but I'm just playing along here...) and just listened to his advisors (which, lets be honest, is all the Dumbass really knows how to do) who were the ones colludin, but in the end gets a arrested for Obstruction of Justice since he tried to stop the investigation! (yeah... forgot about that card on the table, didn't we? :P). Whereas all he had to do was NOT be paranoid and let it go through its normal paces like any normal innocent person would...
Again, do NOT get me wrong! I think at this point that guy is pretty much guilty - I'm just tossing that out there because a) to reply to your idea and, b) more importantly - I'm open-minded enough to NOT be one of those "Locker her up" Anti-Hillary people who deny 8+ Investigations and hearings clearing her of any involvement in Benghazi, so if by some miracle they do come back with an "innocent" verdict I'm not going to be one of you lot who wield pitchforks and torches cus my political opponent doesn't get in trouble.
