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.

Such a system would be very, very expensive and laborious to have, given the kinds of border we have. Scientists and engineers aren't even sure they have the technology to make it work

Smart businesses do not look at labor costs alone anymore. They do look at market access, transportation, telecommunications infrastructure and the education and skill level of the workforce, the development of capital and the regulatory market.

It's all about who gets to work and making sure they're legally present in our country. And to do that nationally E-verify becomes a key component. It certainly needs to available, effective and as inexpensive as possible and that employer needs to use it as a tool. Some of the arguments that are made about how it works or does not work don't carry much water with me. I've already used it for several years. It works.

You can't imagine a world, quite frankly, without a safe and secure aviation system. And so our job is to really focus on that, and what we need to do to keep it safe and secure.

It is fair to say there are individuals in the United States who ascribe to al-Qaeda-type beliefs.

But my view is that you need a system at the border. You need some fencing but you need technology. You need boots on the ground. And then you need to have interior enforcement of our nation's immigration laws inside the country. And that means dealing with the employers who still consistently hire illegal labor.
