Glenn Greenwald (b. 1967) is a US-American political journalist, lawyer, columnist, blogger, and author. He has been a columnist for the US edition of The Guardian since August 2012. Prior to that he was a columnist for Salon.com and an occasional contributor to The Guardian. He was previously a constitutional law and civil rights litigator. He is the author of four books: "How Would a Patriot Act" (a critique of Bush executive power theories, 2006), "Tragic Legacy" (documenting the Bush legacy, 2007), "Great American Hypocrites" (examining the GOP's electoral tactics and the role the media plays in aiding them, 2008) and "With Liberty and Justice for Some: How the Law Is Used to Destroy Equality and Protect the Powerful", Metropolitan Books, 2011. Glenn lives in Rio de Janeiro since 2005.
In June 2013 Greenwald became widely known after The Guardian published the first of a series of reports detailing United States and British global surveillance programs, based on classified documents disclosed by Edward Snowden. The series on which Greenwald worked, along with others, won the 2014 Pulitzer Prize for Public Service. His reporting on the National Security Agency (NSA) won numerous other awards around the world, including top investigative journalism prizes from the George Polk Award for National Security Reporting, the 2013 Online Journalism Awards, the Esso Award for Excellence in Reporting in Brazil for his articles in O Globo on NSA mass surveillance of Brazilians (becoming the first foreigner to win the award), the 2013 Libertad de Expresion Internacional award from Argentinian magazine Perfil, and the 2013 Pioneer Award from the Electronic Frontier Foundation.
In February 2014 he became, along with Laura Poitras and Jeremy Scahill, one of the founding editors of The Intercept. The capitalist providing the financial backing for the new venture was Pierre Omidyar, the eBay founder.
Greenwald is gay, and lives most of the time in Rio de Janeiro, the hometown of his Brazilian partner, David Michael Miranda. In a profile in Out magazine, Greenwald explained that his residence in Brazil was due to the fact that US-American law, the Defense of Marriage Act, barred the federal recognition of same-sex marriages at the time and thus prevented his partner from obtaining immigration rights in the United States (said law was overturned in 2013).
Greenwald and his partner have 11 dogs, all rescued from the street, and he frequently picks up dogs from the street and uses his platforms to find homes for them.
