Christopher David Steele (born 24 June 1964) is a British former intelligence officer with the Secret Intelligence Service MI6 from 1987 until his retirement in 2009.
He ran the Russia desk at MI6 headquarters in London between 2006 and 2009.
In 2009, he co-founded Orbis Business Intelligence, a London-based private intelligence firm.
Steele authored a dossier that claims Russia collected a file of compromising information on U.S.
President Donald Trump.The U.S.
intelligence community probe into Russian interference in the 2016 election were launched due to Steele's dossier.
The House Intelligence Committee, then in Republican control, concluded in an April 2018 report that the probe had been triggered based on information on Trump adviser George Papadopoulos; meanwhile the February 2018 Nunes memo written by staff members for that committee reached the same conclusion.
In December 2019, a report released by U.S.
Inspector General Michael E.
Horowitz determined that Steele was the FBI's lead source during the investigation of Carter Page and that this contributed to the errors which were made during the investigation of Russia's role in aiding Trump's 2016 U.S.
