I think it was okay when Al Gore was doing all that lying to go, I don't know, for a few months. The fact that people oversimplied, well, and the question is, do you know it knowingly?

But the one thing that I have no tolerance for, and I know a lot of people, I'm not going to name names, is to knowingly mislead. That's the only thing.
