Whistleblower, Criminal Defense Litigation Attorney
A former attorney to the United States Department of Justice, Tamm has been classified as a whistleblower when he uncovered warrantless wiretapping by the National Security Agency (NSA) under the Bush Administration. He was one of the anonymous sources for The New York Times reporters, James Risen and Eric Lichtblau in their 2005 article, “Bush Lets U.S. Spy on Callers Without Courts,” which gained attention by the Bush administration and led to a criminal investigation. Tamm eventually told his full story to Newsweek’s, Michael Isikoff in 2008. For his whistleblowing, Tamm was awarded with the Ridenhour Prize for Truth-Telling in 2009.
