"I don't worry too much about what people think about my image, but I think I am pretty polite. My colleagues say I am a gentleman in my dealings with them, even when I disagree. I am difficult because I won't back off on things like the pay raise and the anti-terrorism bill. I'm not a go-along kind of guy. I do respect the institution. I do respect my colleagues. But I didn't go to Washington to make friends. That's not where my friends are."
