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

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.

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.

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

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 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.

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