From Digby at Hullabaloo:
Look, the problem here, again, is not one of just spying on Americans, as repulsively totalitarian as that is. It’s that the administration adopted John Yoo’s theory of presidential infallibility. But, of course, it wasn’t really John Yoo’s theory at all; it was Dick Cheney’s muse, Richard Nixon who said, “when the President does it, that means it’s not illegal.” . . .
I suspect that there are many more of these instances out there in which the administration has simply ignored the law. They believe that the constitution explicitly authorizes them to do so.
