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

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.

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.

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.

I've appointed a task force to take a fresh look at the color-code system and whether we should retain it, change it or scrap it.

There are a number of countries that we see cyber-attacks emanating from. And, again, they can be just individuals who are located in the country. But three that I think are of special concern would be Iran, would be Russia, and China.

Nonetheless, to the extent that terrorists have come into our country or suspected or known terrorists have entered our country across a border, it's been across the Canadian border. There are real issues there.
