"Son, we live in a world that has walls, and those walls have to be guarded by men with guns. Who's gonna do it? ... I have a greater responsibility than you could possibly fathom. ... And my existence, while grotesque and incomprehensible to you, saves lives. You don't want the truth because deep down in places you don't talk about at parties, you want me on that wall, you need me on that wall. I have neither the time nor the inclination to explain myself to a man who rises and sleeps under the blanket of the very freedom that I provide, and then questions the manner in which I provide it. I would rather you just said thank you, and went on your way, Otherwise, I suggest you pick up a weapon, and stand a post. Either way, I don't give a damn what you think you are entitled to!"
Not really, but it amounts to the same thing (h/t TPM):
"There's a lot of speculation about what happened and what didn't happen - I'm not going to talk about it. It's a very sensitive program. I will tell you that, one, the program is necessary to protect the American people, and it's still necessary, 'cause there's still an enemy that wants to do us harm. ... And so there's going to be all kinds of talk about it, and as I say I'm not going to move the issue forward by talking about something as highly sensitive, highly classified subject. I will tell ya, however, that the program is necessary. ... As I said, this is a necessary program that's constantly reviewed and constantly briefed to the Congress."
To clarify, again, the the question that was asked had nothing to do with the nature of the program, but what could be considered "internal" deliberations within the Administration. Bush considers all such deliberations classified, because no one has the right to question him or his decisions. He was forcing through a program which John Ashcroft, for goodness' sake, was against, because Shooter and Torture Boy wanted it. Note, specifically, that he didn't in any way dispute Comey's testimony. To him, it is irrelevant what tactics he chooses, because "If the President does it, it's not illegal."
