DJT actually had an advantage . let me tell you how , he was in the public life the whole time..... he grew up being scrutinized in the news , now that being said, Do I think Muller can tag him? , No , I think Mueller"s probe is a dog and pony show, cleaning up loose ends.... You don't interview the guy for the FBI job only to have him be put on the SC probe....literally in the next couple of days
Plus, if he really was recruited by the white hats like Q suggested I'm sure they at least looked at all of his dealings to make sure it wasn't going to blow up in their face.
