There are those who've been hacked by the Chinese and those who don't know they've been hacked by the Chinese.

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?

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 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.

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.

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