Our process inside the United States government has gotten much better at making sure we touch all possible source of information about a refugee. The interview process has gotten more robust, so we've gotten our act together in that respect. The challenge remains, especially with respect to folks coming from Syria, we're unlikely to have anything in our holdings. That is, with people coming from Iraq, the United States government was there for a very long period of time. We had biometrics, we had source information. We're unlikely to have that kind of picture about someone coming from Syria.

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

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.

The lawyers doing the sorting for Secretary Clinton in 2014 did not individually read the content of all of her e-mails, as we did for those available to us; instead, they relied on header information and used search terms to try to find all work-related e-mails among the reportedly more than 60,000 total e-mails remaining on Secretary Clinton’s personal system in 2014.

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.

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