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.
His work on the NSA files was in part the subject of the film Citizenfour, which won the 2014 Academy Award for Best Documentary. Greenwald appeared onstage at the Oscar ceremony with the film’s director, Laura Poitras, as she accepted the award.
Greenwald lives in Rio de Janeiro, Brazil, the hometown of his partner, David Michael Miranda. Greenwald has stated that his residence in Brazil is the result of an American law, the Defense of Marriage Act, barring federal recognition of same-sex marriages, which prevented his partner from receiving a visa to reside in the United States with him.
