Stephen Kevin Bannon (born November 27, 1953) is an American media executive, political activist, and former investment banker, who is executive chairman of Breitbart News. He served as the White House Chief Strategist (a newly created position) in the administration of US President Donald Trump during the first seven months of Trump's term.[2][3] In this capacity, he attended the Principals Committee of the U.S. National Security Council from January 28, 2017,[4] to April 5, 2017.[5][6]
On August 17, 2016, in the later months of the campaign, Bannon joined Trump's 2016 presidential bid, taking the position of chief executive officer.[7][8] Prior to taking a leave of absence in August 2016, he had been executive chair of Breitbart News, a far-right[i] news, opinion, and commentary website[18][19] which he described in 2016 as "the platform for the alt-right".[I] Bannon left his position in the Trump administration on August 18, 2017; he then rejoined Breitbart News.
Bannon was an officer in the United States Navy for seven years in the late 1970s and early 1980s, serving on the destroyer USS Paul F. Foster as well as at the Pentagon. After his military service, he worked at Goldman Sachs as an investment banker in the Mergers and Acquisitions department. When he left the company, Bannon held the position of vice president. In 1993, he became acting director of the Earth-science research project Biosphere 2. In the 1990s, he became an executive producer in the Hollywood film and media industry; he produced 18 films between 1991 and 2016.
A self-described economic nationalist, Bannon advocates for reductions in immigration,[27] restrictions on free trade with China and Mexico,[28][29] and an increased federal income tax for those earning incomes of over $5 million a year.[30] Bannon is a skeptic of military intervention abroad and has opposed proposals for the expansion of U.S. involvement in Afghanistan,[31] Syria,[32] and Venezuela.[33]
