You’ll have to ask them, but if an anti-encryption bill gets out of the Intelligence Committee, which is where its strength is greatest, I will do everything I can to prevent that. If it goes to the floor, then I will filibuster. I will use every procedural tool to block legislation that in my view would make us less safe and jeopardize our liberty.

There seems to be no change in the standoff between companies that want strong personal privacy and security protections, and law enforcement, which argues that it needs to get past encryption for national security.

There were tens of thousands of news stories during the first days of the encryption discussion that said, “Today, in the ongoing debate between privacy and security, the following happened.”

I don’t think that’s the right way to think about it. I think it is about more security versus less security. If you want to be in a safe community, you shouldn’t be able to weaken encryption.

We pushed back very, very hard on the idea that this is a battle between privacy and security.

Is this a minority point of view or are you seeing more people adopt this?

I think you are starting to see surprising voices in this discussion, like Mike McConnell, the former director of national intelligence, raise questions about what it means to weaken encryption.

What else is coming up for consideration in the cybersecurity space?

Browser spying. Senators John McCain and Richard Burr have a proposal to give any F.B.I. field office new authority to scoop up Americans’ browsing history and a slew of American digital records without going to a judge. Email, text message logs and certain location information would be included. We had a vote on this at the end of June.
