Our investigation looked at whether there is evidence classified information was improperly stored or transmitted on that personal system, in violation of a federal statute making it a felony to mishandle classified information either intentionally or in a grossly negligent way, or a second statute making it a misdemeanor to knowingly remove classified information from appropriate systems or storage facilities.

We did not find direct evidence that Secretary Clinton’s personal e-mail domain, in its various configurations since 2009, was successfully hacked. But, given the nature of the system and of the actors potentially involved, we assess that we would be unlikely to see such direct evidence.

Our focus is and should be on the leakers, not those that are obtaining it as part of legitimate newsgathering.

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.

I believe that Americans should be deeply skeptical of government power. You cannot trust people in power. The founders knew that. That's why they divided power among three branches, to set interest against interest.

I'm in the business where I can't ever say there's no risk associated with someone.

What we do is we combine information collected from any lawful source in a single FBI database so we don't miss a dot when we're conducting investigations in the United States. What we make sure of, though, is nobody gets to see FISA information of any kind unless they've had the appropriate training and have the appropriate oversight.
