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.

The more able we are to keep guns out the hand so criminals and spouse abusers all - the better. So the more information we have the better for law enforcement perspective.

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.

Sometimes the FBI is assigned to do background checks on people who are coming into government in the executive office of the president. Other times, not. A lot of times there are people who are arriving with clearances that already exist.

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.

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

She [Hillary Clinton] used her personal email extensively while outside the United States, including sending and receiving work-related emails in the territory of sophisticated adversaries.
