TCF senior fellow Barton Gellman is featured in the new FRONTLINE special, United States of Secrets

How did the government come to spy on millions of Americans? 

In United States of Secrets, a two-part series airing May 13 and 20, FRONTLINE goes behind the headlines to reveal the dramatic inside story of the U.S. government’s massive and controversial secret surveillance program—and the lengths they went to trying to keep it hidden from the public. 

Part one, from Michael Kirk (League of DenialBush’s War), goes inside Washington to piece together the secret political history of “The Program,” which began in the wake of September 11 and continues today—even after the revelations of its existence by Edward Snowden. 

Then, in part two, Martin Smith (The UntouchablesTo Catch a Trader) explores the secret relationship between Silicon Valley and the National Security Agency: How have the government and tech companies worked together to gather and warehouse your data? 

Part political thriller and part spy novel, United States of Secrets is FRONTLINE's definitive history of domestic surveillance in a post-9/11 world.
