One great lesson from history we need to keep on re-learning. It is that sometimes your adversaries tell you exactly what they're going to do. How many times did [Osama] bin Laden say prior to 9/11 that he was coming after the U.S.? ISIS made clear that when they established their caliphate in Iraq and Syria, they were coming after the United States too.

As the briefer, my job is to carry CIA`s best information and best analysis to the president of the United States and make sure he understands it.

If you were watching CNN, they were saying the NSA is listening to your phone calls. It's reading your emails. When you call your grandma in Arkansas, the NSA knows. All total bulls - t. They made the public more concerned about the privacy issue than the legitimate facts should have done.

The one thing that struck me right off the bat was what Donald Trump said about Benghazi.There is this view out there that [Hillary Clinton] lied about what caused the attack, that she said it was the video.

Donald Trump didn't even understand, right, that [Vladimir] Putin was playing him. So, in Putin's mind, I have no doubt that Putin thinks that he's an unwitting agent of the Russian Federation, although Putin would never say that.

Look at it from [Vladimir] Putin's perspective, right. He's a trained intelligence officer, worked for the KGB, very talented, manipulated people much smarter than Donald Trump. He played this perfectly, right. He saw that Donald Trump wanted to be complimented.
