FBI can investigate (a la Mueller’s gang) until the cows come home, but the FBI or the DOJ or any one else have no constitutional authority to stop the US senate from confirmation vote.
The FBI investigation is not the problem, the problem is there are less than 50 senators willing to vote yes right now. If repubs had 51 votes (incl Pence) it does not matter where FBI is at in their investigation. The real problem is Flake, Murky and Collins.
Therefore, the FBI IS a part of the ongoing smear crusade, whether it wants to be or not....and some of the investigators may very well be hard-core anti-Trumpers.
EVERYONE and EVERYTHING matters in this horror show, including the new FBI probe...and I simply can't trust all of the players in this bureau right now.
