One of the most striking elements of today's threat picture is that plots to attack America increasingly involve American residents and citizens.

It would be unwise to say the least, irresponsible of us at the TSA, at the Homeland Security Department not to evolve our technology to match the changing threat environment that we inhabit.

I believe we have to move, eventually in our country, toward a system of public financing that really works for candidates running for federal office. I will support that as president.

What we're doing is making sure that we have a safe and secure border region from San Diego all the way to Brownsville. And that means manpower, it means technology, it means infrastructure, it means interior enforcement. All, you know, kind of layered in appropriate ways, and making sure, like I said before, the border is safe and secure.
