Comey stated in July that after a thorough year long investigation the agency did not find any evidence that any prosecutor could use to further investigate or indict Hillary Clinton. That announcement was unprecedented but welcome news to me of course but then he proceeded to editorialize about his ideas of how careless Clinton had been. Totally over the top by the self righteous  FBI head. That announcement however caused radical elements inside the FBI to be enraged and then again when the DOJ and FBI senior staff ordered them to stand down from further investigating the Clinton Foundation because the rogue agents suspicions came from a right wing writer's scurrilous, unsubstantiated allegations in a fact free book sponsored by Steve Bannon the head of Trumps campaign. Once again there was nothing there to investigate and the higher ups in the FBI and at the DOJ recognized this when presented with the details of what agents had "discovered" so far. Comey has lost control of the FBI.
