Bush Administration in the aftermath of the September 11 attacks. He became a vocal critic of the Iraq War and has maintained a critical position of American foreign policy. Greenwald started contributing to Salon in 2007, and to The Guardian in 2012. In June 2013, while at The Guardian, he began publishing a series of reports detailing previously unknown information about American and British global surveillance programs based on classified documents provided by Edward Snowden. His work contributed to The Guardian and The Washington Post won a Pulitzer Prize, and he won the 2013 George Polk Award along with three other reporters, including Laura Poitras. In 2014, Greenwald, Poitras, and Jeremy Scahill launched The Intercept, for which he was co-founding editor until he resigned in October 2020. Greenwald subsequently started publishing on Substack, an online newsletter-based journalism platform.
