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

And we ask the American people to play an important part of our layered defense. We ask for cooperation, patience and a commitment to vigilance in the face of a determined enemy.

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.

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.

If American schooling is inadequate now, just imagine how much more obsolete it will be when today's kindergarten students graduate from high school in just 12 years.

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.

It drove home, personally, the value of early detection and education and intervention.
