Glenn Edward Greenwald (born March 6, 1967) is an American journalist and author. He is best known for a series of reports published from June 2013 by The Guardian newspaper detailing the United States and British global surveillance programs, and based on classified documents disclosed by Edward Snowden. Greenwald and the team he worked with won both a George Polk Award and a Pulitzer Prize for those reports. He has written several best-selling books, including No Place to Hide.
Before the Snowden file disclosures, Greenwald was considered one of the most influential opinion columnists in the United States. After working as a constitutional attorney for ten years, he began blogging on national security issues before becoming a Salon contributor in 2007 and then for The Guardian in 2012. He now writes for (and has co-edited) The Intercept, which he founded in 2013 with Laura Poitras and Jeremy Scahill.
