Where's Rudy Giuliani on the NSA Surveillance Program? Has the White House Contacted Him? Will He Testify at the Congressional Hearings?

With Congressional hearings set and as today's front-page New York Times story indicates, the NSA spying controversy isn't going to fade away. Opponents of the program claim the president broke the law, while supporters say the president has the constitutional and statutory authority to conduct the surveillance. There are also some who believe it's a close call but also maintain that the president has the unique responsibility to defend the nation and acted accordingly.

But where does Mayor Giuliani stand? Will Sen. Arlen Specter invite the mayor to give his perspective on the program? My guess is that the mayor generally backs the president's decision to implement the surveillance and given his background is someone the American people should hear from.
