Straight from the horse's mouth:

Q Yesterday we were told that Karl Rove had no role in it --

THE PRESIDENT: Yes.

Q -- have you talked to Karl and do you have confidence in him --

THE PRESIDENT: Listen, I know of nobody -- I don't know of anybody in my administration who leaked classified information. If somebody did leak classified information, I'd like to know it, and we'll take the appropriate action. And this investigation is a good thing.

And again I repeat, you know, Washington is a town where there's all kinds of allegations. You've heard much of the allegations. And if people have got solid information, please come forward with it. And that would be people inside the information who are the so-called anonymous sources, or people outside the information -- outside the administration. And we can clarify this thing very quickly if people who have got solid evidence would come forward and speak out. And I would hope they would.

And then we'll get to the bottom of this and move on. But I want to tell you something -- leaks of classified information are a bad thing. And we've had them -- there's too much leaking in Washington. That's just the way it is. And we've had leaks out of the administrative branch, had leaks out of the legislative branch, and out of the executive branch and the legislative branch, and I've spoken out consistently against them and I want to know who the leakers are.

So, in other words, maybe he has, maybe he hasn't, and no way he's telling you. I'd still maintain that the only other way they could be so sure it wasn't Rove would be if they do know themselves who did the leaking. Either way, he sure as heck doesn't want to talk about Rove, though.
