Harold III investigated Benghazi.
He didn't discover that Hillary was shipping arms into Syria? Why was Stevens at the compound on 9/11 at all??
All hat, no cattle.
If Muelller and his investigation finds anything whatsoever at all that Trump might have broken the law on anything in his life, Mueller will seek an indictment. This is far past Russian collusion, the supposed reason for Special Counsel, and is a witch hunt to find something for which Trump can be impeached, no matter what the offense or circumstances.
Trump should appoint a Special Prosecutor to look into Mueller & Uranium 1. Best defense is a good offense.
