No thanks, I'm simply not interested in your digression. The topic under discussion is the legality of the President conducting warrantless foreign intelligence intercepts. Do you have something to add to that, or don't you?
Which is answered by the fact that Congress has the constitutional authority to regulate his behavior in that area. It has every bit as much power to regulate him in that area as in any other area where he's authorized to act, such as domestic law enforcement. And you've provided no evidence that any appellate court has issued any holdings (as opposed to dicta) to the contrary.
