You have no idea, what I believe. It is people like you that keep the collusion stuff alive. Crack a book sometime. Hell, do an internet search. There is no Federal Statute against collusion and never has been. If you get down to it, that is why trumpers like to keep talking about it, simply because it is a charge, ill-defined and totally without penalty of law, unlike some of the crap he has been into.
Be that as it may and under our laws, that's the way it is. You should forget collusion, as not being charge with it here either, and concentrate on 12 boxes of documents, he was forced to give back whether he wanted to or not, that it appears contains classified files.
