Thomas Tamm was a lawyer in the Office of Intelligence Policy and Review at the U.S. Department of Justice when he tipped off New York Times reporters James Risen and Eric Lichtblaw to warrantless surveillance of U.S. citizens by the National Security Agency.  Using information provided by multiple sources, the reporters published an expose on December 15, 2005.  The Justice Department opened an investigation into Tamm’s disclosure, but later dropped the investigation.  Tamm was awarded the Ridenhour Truth-Telling Prize for 2009.
