We stopped the fighting in 1991 on an agreement that Iraq would take steps to assure the world that it would not engage in further aggression and that it would destroy its weapons of mass destruction. It has refused to take those steps. That refusal constitutes a breach of the armistice which renders it void and justifies resumption of the armed conflict.

For senators to complain that they didn't know this was happening, we had many, many meetings that have been both classified and unclassified that members have been invited to.

He [Mitt Romney] didn't pay taxes for 10 years! Now, do I know that that's true? Well, I'm not certain, but obviously he can't release those tax returns. How would it look?

I deeply regret using such a poor choice of words.

I believe myself that the secretary of state, secretary of defense and - you have to make your own decisions as to what the president knows - (know) this war is lost and the surge is not accomplishing anything as indicated by the extreme violence in Iraq yesterday.

Do you know how I feel about that? I'm sure this is no big surprise... what a mistake. I should never have voted for that, but I accepted what [former Secretary of State] Colin Powell and the others said. But it took me just a matter of a few months to realize it was a bad mistake, and my record speaks for itself. I've spoken out against what was going on, not once, not twice, but lots of times. And I'm sorry that I was misled, but I was, and it was a mistake for me to vote for that war.

We would be somewhat foolish to work out something on stopping us from going over the cliff and then a month or six weeks later Republicans pull the same game they did before and say, 'We're not going to do anything - unless this happens, we're not going to agree to increasing the debt ceiling.' I agree with the president, it has to be a package deal.
