Many lawmakers were stunned by recent press reports, denied but not corrected by the Justice Department, that the FBI has issued as many as 30,000 \"national security letters\" since the law was passed nearly unanimously in 2001. The letters order private and public entities to turn over records and other private data about Americans - and remain silent about it.
