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.

We all love privacy. We all care about public safety. And none of - at least people that I hang around with, none of us want back doors. We don't want access to devices built-in in some way.

There is evidence that Democrates were extremely careless in their handling of very sensitive, highly classified information.

There are two things that matter in a criminal investigation of a subject.What did the person do, and when they did that thing, what were they thinking? When you look at the hundred-years-plus of the Justice Department investigation and prosecution of mishandling of classified information, those two questions are obviously present.

WikiLeaks is a important focus of our attention.

Only a very small number of the e-mails containing classified information bore markings indicating the presence of classified information. But even if information is not marked 'classified' in an e-mail, participants who know or should know that the subject matter is classified are still obligated to protect it.

We have no basis to conclude she [Hillary Clinton] lied to the FBI.

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.

The FBI also discovered several thousand work-related e-mails that were not in the group of 30,000 that were returned by Secretary Clinton to State in 2014... I should add here that we found no evidence that any of the additional work-related e-mails were intentionally deleted in an effort to conceal them.

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?

Our need for public safety and our need for privacy are crashing into each other and we've got to sort that out.

The Obama administration was not in a position where they were seeking legislation. I don't know yet how President Trump intends to approach this. I know he spoke about it during the campaign. I know he cares about it, but it's premature for me to say.

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.

I shouldn't talk about individuals in an open forum, at least without thinking about it better.

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.

Half of the devices that we encounter in terrorism cases, in counterintelligence cases, in gang cases, in child pornography cases, cannot be opened with any technique. That is a big problem. And so the shadow continues to fall.
