the FBI agent who was complained to stepped out of the chain of command and apparently went to a House Republican leader, rather than anybody upstairs. Do you think that there's potential -- you put all that together -- do you think that's a greater potential national security threat than what you're talking about?

You could watch the veins begin to bulge on Grumpy's neck and forehead as this question went along, and so naturally he burst like a festering pustule when it was done:

MCCAIN: Well, I say with great respect, that’s one of the dumbest questions I’ve ever heard. -- I’m answering your question. Do you want me to answer your question or do you want to interrupt? Which do you want? -- There are four dead Americans. The lives of other Americans were put in jeopardy.

This is a matter of four dead Americans. I think that the other issue raised is very serious, and I think it deserves a thorough and complete investigation — but it does not rise to the level of an attack on an American consulate that took four American lives.

OK, just so we're clear: Potential security threat created that exposes possible Republican chicanery? Never an issue. Tragic incident in which intelligence details remain unclear, so it can be endlessly exploited? Yeh, that's what gets Grumpy's attention.
