I have long been a proponent of a guest-worker program between the United States and Mexico, and in particular I have proposed that Arizona would be an ideal location for a pilot project.

It's always been government's role to protect the security of the nation. And cyber-attacks is a security issue, from our perspective. And it's a security issue of particular concern with respect to the nation's core critical infrastructure, the infrastructure everyone relies on, the energy sector, the telecommunications sector, the banking sector.

Bob Mueller for the FBI, myself, met with a particular group of executives that have major roles in the so-called ISPs, the Internet service providers, what they could possibly do. We have met with leaders in private industry in terms of the core critical infrastructure of the country as to what they can possibly do with cyber-attacks.

I'm angry that the private sector, which is supposed to be in charge of running gasoline into the Valley, doesn't have its act together to deal with a critical situation, so now the public sector has to step in.

Well, you know, I think in conversations with members of the Senate and others, they all recognize that the issue of immigration is important. It's important to our nation, it's important to our public safety, it's important to our security, it's important to our economic well-being moving forward. And it's not something that's going to go away.

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.

You show me a 50-foot wall and I'll show you a 51-foot ladder.
