You have probably already heard about Cheney's use of the F word on Thursday. From an interview with FOX News:

And I informed him [Leahy] of my view of his conduct in no uncertain terms. And as I say, I felt better afterwards.

Ultimately, that is what is most important - feeling better about yourself. It get better, though:
CAVUTO: What was reaction from the crowd?

CHENEY: Well, I think that a lot of my colleagues felt that what I had said badly needed to be said, that it was long overdue.

CAVUTO: Pretty feisty guy, aren't you?

CHENEY: Well, I'm usually fairly calm (UNINTELLIGIBLE).

CAVUTO: Your wife's just a few feet away.

CHENEY: And ordinarily I don't express myself in strong terms. But I thought it was appropriate here.
