Former CIA Director John Brennan said he is "concerned" that he is "supposedly" going to be interviewed by John Durham, the U.S. attorney leading the Justice Department's review of the origins of the Russia investigation. Attorney General William Barr has ordered an "investigation into the investigators" that has now spiraled into an impeachment inquiry after it was revealed that the president asked the leader of the Ukraine to cooperate with the investigation. "Given that Barr is now accompanying Durham on these things, it really makes me think that the hand of politics and of Trump are now being used to massage what this ongoing review quasi-investigation is. So I am concerned," Brennan said on MSNBC's "Deadline" with former Bush press secretary Nicole Wallace. "I am still very puzzled and troubled by Donald Trump's actions vis-a-vis Russia. It is something that makes me wonder, what is at the root of some of his actions and decisions?" Brennan stated. Brennan said he "hopes" more people inside the government and intelligence community will "speak out" about the president's actions "because clearly Donald Trump is unable to protect the rights, liberties, and freedoms of this country."
