The Clinton investigation was a completed investigation that the FBI had been deeply involved in, so I had an opportunity to understand all the facts and apply those facts against the law as I understood them. This investigation was under way - still going when I was fired. So it's nowhere near in the same place.

In our counterterrorism cases and our counterintelligence cases, we can issue all kinds of - of layers of approval in the FBI, a national security letter to find out the subscriber to a particular telephone number and to find out what numbers that telephone number was in contact with. Not the content of those communications, but just the connection.

In my view, a huge portion of WikiLeaks's activities has nothing to do with legitimate newsgathering, informing the public, commenting on important public controversies, but is simply about releasing classified information to damage the United States of America.

In their minds, the murderers and accomplices of Germany, and Poland, and Hungary, and so many, many other places didn't do something evil. They convinced themselves it was the right thing to do, the thing they had to do. That's what people do. And that should truly frighten us.

Although we did not find clear evidence that Secretary Clinton or her colleagues intended to violate laws governing the handling of classified information, there is evidence that they were extremely careless in their handling of very sensitive, highly classified information.

Secretary Hillary Clinton used several different servers and administrators of those servers during her four years at the State Department. She also used numerous mobile devices to send and to read email on that personal domain.

What we want to work with manufacturers on is to figure out how can we accommodate both interests in a sensible way? How can we optimize the privacy, security features of their devices and allow court orders to be complied with?
