AT&T may be in the clear with NSA madness?

AT&T may be in the clear now with with NSA wiretapping madness. According to federal law, 18 U.S.C. 2511, they only need a written certification by the Attorney General to not need a warrant or court order to provide information to a government agency. While AT&T has yet to produce such a document, there apparently have been hinting towards having such a document.
In any case, AT&T will be taking flak from consumers for providing such information regardless and not stepping up to protect privacy rights as Google tried to do did a short while ago.
The EFF class-action lawsuit has been relentlessly trying to obtain a glimpse at if this document exists. In accordance to 18 U.S.C. 2511, the corporation would be subject to fines if they disclosed involvement which is why AT&T if hiding behind this federal law, has been very quiet.
