Following the attacks of September 11, 2001, the National Security Agency stepped up its efforts to collect intelligence domestically by filtering millions of phone conversations and e-mail messages. In his new book, The Shadow Factory, journalist James Bamford reveals that the ultra-secret agency has half a million people on its watch lists.

Bamford is the former investigative producer for ABC's World News Tonight with Peter Jennings. He's the author of the bestsellers Body of Secrets and The Puzzle Palace. He's also written investigative cover stories for The New York Times Magazine, The Washington Post Magazine, and the Los Angeles Times Magazine. His new book is A Pretext for War: 9/11, Iraq, and the Abuse of America's Intelligence Agencies.

James Bamford has investigated the inner-workings of the National Security Agency for his new book, Body of Secrets: Anatomy of the Ultra-Secret National Security Agency: From the Cold War Through the Dawn of a New Century (Doubleday). The book examines the Agency's past and its present activities including the ongoing hunt for the terrorist Osama bin Laden.
