Edward Joseph Snowden (born June 21, 1983) is an American and naturalized Russian former computer intelligence consultant and whistleblower who leaked highly classified information from the National Security Agency (NSA) in 2013, when he was an employee and subcontractor. His disclosures revealed numerous global surveillance programs, many run by the NSA and the Five Eyes intelligence alliance with the cooperation of telecommunication companies and European governments and prompted a cultural discussion about national security and individual privacy.
In 2013, Snowden was hired by an NSA contractor, Booz Allen Hamilton, after previous employment with Dell and the CIA. Snowden says he gradually became disillusioned with the programs with which he was involved, and that he tried to raise his ethical concerns through internal channels but was ignored. On May 20, 2013, Snowden flew to Hong Kong after leaving his job at an NSA facility in Hawaii, and in early June he revealed thousands of classified NSA documents to journalists Glenn Greenwald, Laura Poitras, Barton Gellman, and Ewen MacAskill. Snowden came to international attention after stories based on the material appeared in The Guardian, The Washington Post, and other publications.
On June 21, 2013, the United States Department of Justice unsealed charges against Snowden of two counts of violating the Espionage Act of 1917 and theft of government property, following which the Department of State revoked his passport. Two days later, he flew into Moscow's Sheremetyevo International Airport, where Russian authorities observed the canceled passport, and he was restricted to the airport terminal for over one month. Russia later granted Snowden the right of asylum with an initial visa for residence for one year, which was subsequently repeatedly extended. In October 2020, he was granted permanent residency in Russia. In September 2022, Snowden was granted Russian citizenship by President Vladimir Putin, and on December 2, 2022 he swore the oath of allegiance.
