[I am sure he would say anything to bring Trump down]
I just want to make this perfectly clear.  You are rejecting what McMullin said in his official capacity WHILE HE WAS POLICY DIRECTOR OF THE HOUSE REPUBLICAN CONFERENCE?  It seems that God could come down and tell you it happened and you stick your head in the sand and go, "lalalalala!"
Regardless of whether or not you recognize the source as official it is anything but "scant sourced."
