I can't see a flaw in the author's general point that Congress does have the power to stop the President from doing this. But I don't see in FISA where the President is NOT allowed to eavesdrop on communications going overseas.
So if they really feel the President shouldn't be doing this, Congress is free to enact a law preventing him from doing so, and to try to override his veto.
Wait, nevermind, Bush lost his veto pen, hasn't used it once in office. Maybe he'll find it for this and then start to veto the other crap legislation like the stuff that he's been signing so far.
