One of the great strengths of America is our active public square. Issues are influenced by the will of the people. That is why an educated citizenry is so important to the success of our country. As SMU graduates, you are well-equipped to participate in these vital debates. My hope is that you speak out on the issues that matter to you. Participate in your Nation's civic life as citizens, not spectators. You'll come to learn that who you are is more important than what you have—and that you have responsibilities to your fellow citizens, your country, and your family. By taking part in American democracy, you will make our country stronger.

We must reduce pressure on our border by creating a temporary worker plan. Willing workers ought to be matched with willing employers to do jobs Americans are not doing for a temporary -- on a temporary basis.

For those too young to recall that clear September day, it is hard to describe the mix of feelings we experienced. There was horror at the scale -- there was horror at the scale of destruction, and awe at the bravery and kindness that rose to meet it. There was shock at the audacity -- audacity of evil -- and gratitude for the heroism and decency that opposed it. In the sacrifice of the first responders, in the mutual aid of strangers, in the solidarity of grief and grace, the actions of an enemy revealed the spirit of a people. And we were proud of our wounded nation.

The situation in Iraq is unacceptable to the American people; and it is unacceptable to me. Our troops in Iraq have fought bravely. They have done everything we have asked them to do. Where mistakes have been made, the responsibility rests with me.

he spoke out forcefully against leakers, including former CIA agent Philip Agee, who had just released a tell-all book. My father could forgive a lot of mistakes, but he believed that it was disgraceful for a man to violate his oath and reveal state secrets, especially when it could lead to the loss of innocent American life.
