There is no doubt that Saddam Hussein's regime is a serious danger, that he is a tyrant, and that his pursuit of lethal weapons of mass destruction cannot be tolerated. He must be disarmed.

The stark and tragic images of human suffering in the aftermath of Hurricane Katrina have reminded us yet again that civil rights and equal rights are still the great unfinished business of America. The suffering has been disproportionately borne by the weak, the poor, the elderly and infirm, and largely African-Americans, who were forced by poverty, illness, unequal opportunity to stay behind and bear the brunt of the storm's winds and floods. I believe that kind of disparate impact is morally wrong in this, the richest country in the world.

I don't think America can just drill itself out of its current energy situation. We don't need to destroy the environment to meet our energy needs. We need smart, comprehensive, common-sense approaches that balance the need to increase domestic energy supplies with the need to maximize energy efficiency.

Although my doctors informed me that I suffered a cerebral concussion, as well as shock, I do not seek to escape responsibility for my actions by placing the blame either on the physical and emotional trauma brought on by the accident, or on anyone else.

For all my years in public life, I have believed that America must sail toward the shores of liberty and justice for all. There is no end to that journey, only the next great voyage. We know the future will outlast all of us, but I believe that all of us will live on in the future we make.

I hope for an America where the power of faith will always burn brightly, but where no modern inquisition of any kind will ever light the fires of fear, coercion, or angry division.

My colleague Sen. Rick Santorum, Pennsylvania Republican, erroneously suggested that I support the teaching of intelligent design as an alternative to biological evolution.

Unlike biological evolution, intelligent design is not a genuine scientific theory and, therefore, has no place in the curriculum of our nation's public school science classes.
