I hope that the states are taking seriously their obligations to harden the cybersecurity around the election infrastructure that Americans rely upon and need.

I think that the potential for homegrown terrorist attacks is something that we have to be very concerned about, because, in many respects, it's harder to detect when you have an independent actor who may be living in our midst, in our own communities.

I'll never forget what a Catholic priest told me; he said, "If you try to padlock the door, you have to give people an alternative path - an alternative, safer path. You can't padlock, and you shouldn't padlock a burning building."

There's a lot of sensitivity about federal involvement in elections around the country. I think that it would be appropriate to consider - whether there should be some basic federal minimum standards to the cybersecurity around the election infrastructure. We have federal standards for aviation security, for auto safety, for a lot of things, and elections are pretty important in the country.

We are very definitely in a new phase in the global terrorist threat where the so-called lone wolf could strike at any moment.

I hope that the states are taking seriously their obligations to harden the cybersecurity around the election infrastructure that Americans rely upon and need.

Politics, in my judgment, has become not just the means to a policy ends, but it's become the end itself. Politics has become the sport that we all watch, and we all pay attention to.
