The Washington Post is reporting that federal investigators have concluded that Republican Sen. Richard C. Shelby of Alabama divulged classified intercepted messages to Fox News and CNN while he served on the Senate Select Committee on Intelligence. But the Justice Department has decided not to undertake a criminal prosecution against the Republican Senator.

Shelby revealed that the National Security Agency intercepted messages in Arabic on the eve of Sept. 11 that said “The match is about to begin” and “Tomorrow is zero hour.” He also revealed that the messages were not translated until after the Sept. 11 attacks.
