Glenn Greenwald is an investigative journalist and columnist for First Look Media. Formerly a constitutional and civil rights lawyer, he is the author of the three New York Times bestselling books, including How Would a Patriot Act? in 2006 and With Liberty and Justice for Some in 2011.

The Atlantic named him one of the “25 Most Influential Political Commentators” and Foreign Policy called him one of the “Top 100 Global Thinkers” of 2013. His latest book, No Place to Hide: Edward Snowden, the NSA, and the U.S. Surveillance State, will be released on April 29th.

Greenwald became a political writer in 2005. He was a columnist at The Guardian and Salon, writing about civil liberties, national security, and US political and media culture. He won numerous awards for his work, including the first annual I.F. Stone Award for Independent Journalism in 2009, and an Online Journalism Association Award for his investigative work on the abusive detention conditions of Bradley Manning.

In June 2013, Greenwald published the first of many stories related to classified N.S.A. surveillance programs from the trove of documents leaked by Edward Snowden. His NSA reporting has won numerous prizes around the world, including the top Online Journalism Association award for investigative journalism, the Esso Award for Reporting in Brazil, and the Pioneer Award of 2013 from the Electronic Frontier Foundation.

“Surveillance equals power. The more you know about someone, the more you can control and manipulate them in all sorts of ways. That is one reason a Surveillance State is so menacing to basic political liberties.”
