Here is an actual exchange between Scott McClellan and a reporter earlier this week (courtesy of Editor and Publisher):

Q: Scott, I just have two quick follows to some questions that were asked earlier. One, are you trying -- are you saying that, CIA leak aside, you can't say that the President has full confidence in Karl Rove?

MR. McCLELLAN: Maybe you didn't hear what I was saying earlier. I said, what I said previously still stands.

Q: What did you say previously? You say that all the time.

MR. McCLELLAN: You can go back and look at it. I'll be glad to share the transcript of when that question came up last time.

Q: Either he does or he does not. So he does have full confidence?

MR. McCLELLAN: We've already addressed that, Jim.

Q: Why can't you repeat it?

Q: But why can't -- if you've addressed it, why can't you repeat it for me? Clearly --

MR. McCLELLAN: Why do you have to keep asking a question that I've already answered when --

Q: Because I don't know the answer.

MR. McCLELLAN: No, because you're asking in the context of an ongoing investigation. And it's very easy to go and look at our transcripts and pull that information --

Q: That's why I said -- that's why I said, "set the leak aside," just in general are you refusing to --

MR. McCLELLAN: Yes. And I said I stand by what I said previously.

Q: Okay, topic two, since you won't answer that question.

MR. McCLELLAN: I did answer that question.
