As part of our layered approach, we have expedited the deployment of new Advanced Imaging Technology (AIT) units to help detect concealed metallic and non-metallic threats on passengers. These machines are now in use at airports nationwide, and the vast majority of travelers say they prefer this technology to alternative screening measures.

We are on the lookout for criminal and terrorist activity but we do not nor will we ever monitor ideology or political beliefs.

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 believe that Streamline should be part of our toolbox of things that we use at the border. And there needs to be a variety of things that we use at the border to get the most effective enforcement strategy. And so really it's a resource issue more than anything else.

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.

Each and every one of the security measures we implement serves an important goal: providing safe and efficient air travel for the millions of people who rely on our aviation system every day.

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