http://www.dailymail.com/news/News/2005122236/Because of a clause in federal law, Democratic U.S. Senator Jay Rockefeller could not bring to the Senate floor his concerns about President George W. Bush's executive authorization of a domestic spying program, his office said.
A section of the 1947 National Security Act says if the president determines information related to covert programs is particularly sensitive, the so-called "Gang of 8" are the only ones who can know about it.
Some have questioned the legality of the National Security Agency program, because warrants were not first obtained from a special federal court. The program monitored international telephone calls and e-mails of American citizens suspected of being associated with terrorism after September 11, 2001.
