He was a daily intelligence briefer for President Clinton. For President Bush, he served as Deputy CIA Director and Director of National Counterterrorism Center. Under President Obama, he was the Director of the CIA. He is not partisan or a politician.
But Donald Trump scares him. Here is what he had to say about Trump in an interview with NBC News:
“It is no secret to anybody that Donald Trump was ill-prepared and inexperienced in terms of dealing with matters that a head of state needs to deal with.
“I think this is now coming to roost and I am really worried particularly the reports of the last couple of days, I think he must be feeling the pressure.
“I had been very angry at Donald Trump for the things he said and the things he did - I am now moving into the realm of deep worry and concern, our country needs strong leadership.
“Our country needs confidence that we are going to be able to deal with Mr Putin who is once again flexing his muscles on the military front, that we can deal with North Korea.
“If we have somebody in the Oval Office who is unstable, inept, inexperienced and also unethical, we really have rough waters ahead.
“I do think it’s unfortunately going to get a bit more painful, a bit worse before it gets better.
“I do hope we are going to be able to get through this very, very difficult chapter in our history without incurring damage that could be long-lasting.”
