Most of you probably didn't know that I have a new book out. Some guy put together a collection of my wit and wisdom - or, as he calls it, my accidental wit and wisdom. But I'm kind of proud that my words are already in book form.

I don't want some mom whose son may have recently died to see the commander in chief playing golf. I feel I owe it to the families to be in solidarity as best as I can with them. And I think playing golf during a war just sends the wrong signal.

We do not know how much our climate could or will change in the future. We do not know how fast change will occur or even how some of our actions could impact it.

I hope we get to the bottom of the answer. It's what I'm interested to know.

I regret the fact that Saddam [Hussein] didn't have weapons of mass destruction that we thought. I don't regret removing him from power.

We have also discovered through intelligence that Iraq has a growing fleet of manned and unmanned aerial vehicles that could be used to disperse chemical or biological weapons across broad areas.

Perceptions change with time and you can't rush it, in my judgment.
