This asshat has got to go. I have refrained from voting for this jerk in two elections. Time is overdue for him to GO.
Get this guy in an interview and ask him point blank: what specific actions are you talking about along with the evidence they actually happened. If he says anything beyond the normal blather, ask him if someone denies something he is accused of doing, is that obstruction. If he says yes, ask him if he ever heard of the 5th and 6th amendments along with the first.
