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.

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.

The United States and Arizona are both losing jobs to offshore locations.

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.

We have at least 125 communities in Arizona at risk from wildfire, not because of review processes or litigation delays but because of a lack of federal funding on the ground to actually begin the projects.

Public schools were designed as the great equalizers of our society - the place where all children could have access to educational opportunities to make something of themselves in adulthood.

And I am also here to say that if something were to happen, we are prepared to respond swiftly, to respond effectively, and to respond strongly. That is our tradition as a country. And that is a tradition that we will uphold, regardless of any circumstance because this nation is one that is very, very strong and, indeed, extraordinarily resilient.

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.

Let me be very clear: We monitor the risks of violent extremism taking root here in the United States. We don't have the luxury of focusing our efforts on one group; we must protect the country from terrorism whether foreign or homegrown, and regardless of the ideology that motivates its violence.

It would be unwise to say the least, irresponsible of us at the TSA, at the Homeland Security Department not to evolve our technology to match the changing threat environment that we inhabit.

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.

The last thing the Department of Homeland Security is about is infringing on anybody's constitutionally protected rights.

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.

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.

Now, a lot of what we are doing right now, quite frankly, is because of what happened on Christmas. Many of the things were kind of in the works. We were already planning, for example, the purchase and deployment of advanced imaging technology. You call them body scanners. We call them AITs (Advanced Imaging Technologies).

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, the violence is mostly in Mexico itself, at least the violence that people are worried about. And so we want to make sure that violence does not spill over into our communities that are along the border.

The great thing about this town hall format is that it allows us to hear what's on the minds of Americans. Tonight, it was clear - voters have quite a few questions about the direction in which the current administration is headed.

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.

We've probably gotten 500 calls from people saying what the heck is going on with gas, and I gotta say I agree with you. What the heck is going on with gas?

All images generated by imaging technology are viewed in a walled-off location not visible to the public. The officer assisting the passenger never sees the image, and the officer viewing the image never interacts with the passenger. The imaging technology that we use cannot store, export, print or transmit images.

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.

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.

So not only do we need to deal with threats as they emerge, we have to be thinking in anticipation of future threats, and the things we do have to be things that enable the system to continue to work.

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.

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.

We are on the lookout for criminal and terrorist activity but we do not - nor will we ever - monitor ideology or political beliefs. We take seriously our responsibility to protect the civil rights and liberties of the American people, including subjecting our activities to rigorous oversight from numerous internal and external sources.

Today in America, we are trying to prepare students for a high tech world of constant change, but we are doing so by putting them through a school system designed in the early 20th Century that has not seen substantial change in 30 years.

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.

We used to think that revolutions are the cause of change. Actually it is the other way around: change prepares the ground for revolution.

I must stress here the point that I appreciate clarity, order, meaning, structure, rationality: they are necessary to whatever provisional stability we have, and they can be the agents of gradual and successful change.

Excuses change nothing, but make everyone feel better.

So, first you have to be able to play with a metronome. Then you take your freedom. If you play in an orchestra, you got to watch the conductor, he is like a metronome, but it is more difficult because he can change rhythms.

I wouldn't change Buffy for anything and I wouldn't change the course in which she has evolved but it is nice to be able to do something that is a little different.

For example, UNICEF works with governments to change legislation such as in India where a law was passed raising the age of compulsory school completion to keep children in school and away from the workplace for longer.

Great joy, especially after a sudden change of circumstances, is apt to be silent, and dwells rather in the heart than on the tongue.

I still feel that a movie has to attempt to say something - even if it fails miserably. But I've sort of given up on believing that I'm going to change the world with every film I choose to act in.

Don't knock the weather; nine-tenths of the people couldn't start a conversation if it didn't change once in a while.

You don't have to be the Dalai Lama to tell people that life's about change.

I knew that my staying up would not change the election result if I were defeated, while if elected I had a hard day ahead of me. So I thought a night's rest was best in any event.

It will always be a battle a day between those who want maximum change and those who want to maintain the status quo.

Being a father, well, I don't know if this is a change, but it makes me want to get out of here faster. Get off the clock. Just 'cause the baby is my reason for living, my reason for coming to work.

A liberal knows that the only certainty in this life is change but believes that the change can be directed toward a constructive end.

I was born not knowing and have had only a little time to change that here and there.

In their search for quality, people seem to be looking for permanency in a time of change.

The game has kept faith with the public, maintaining its old admission price for nearly thirty years while other forms of entertainment have doubled and tripled in price. And it will probably never change.

One day I actually took the list into the bathroom and I put it up against my face and looked in the mirror and I realized I had one of two choices, change the list or change myself.

But the real focus should be on people who are buying today because the base is so big it will take a long time for any change materialize on an overall basis.

Markets change, tastes change, so the companies and the individuals who choose to compete in those markets must change.
