As far as we can tell, there are three possible explanations for Mr. Gonzales’s talk about a dispute over other — unspecified — intelligence activities. One, he lied to Congress. Two, he used a bureaucratic dodge to mislead lawmakers and the public: the spying program was modified after Mr. Ashcroft refused to endorse it, which made it “different” from the one Mr. Bush has acknowledged. The third is that there was more wiretapping than has been disclosed, perhaps even purely domestic wiretapping, and Mr. Gonzales is helping Mr. Bush cover it up.
New York Times lead editorial. Emphasis mine. Because my guess is that's what the secrecy is all about.
