He never will. By indicting Russian agents he knows he can never try, all “evidence” or lack thereof can be locked away as part of an “ongoing case”. If he ever ends his investigation you will never see a report, anymore than the DOJ ever issued reports on any Obama scandals. That’s why he investigated the Russians. He can point to the indictments as proof it wasn’t a witch hunt, while never having to provide evidence of anything.
I meant “indicted the Russians”.
