Andrew G. McCabe served as deputy director of the Federal Bureau of Investigation from February 2016 to January 2018. With less than two days before his scheduled retirement in March 2018, McCabe was fired by Attorney General Jeff Sessions in what many view as a politically motivated act, following his opening of counterintelligence and obstruction of justice investigations into President Trump. He began his career at the FBI in 1996, working first as a street agent on the Eurasian Organized Crime Task Force, and eventually as its supervisor. Later, he led the FBI's Counterterrorism Division, the National Security Branch, and the Washington Field Office, and was the first director of the High-Value Detainee Interrogation Group, which developed new methods for lawfully and effectively questioning suspected terrorists. McCabe is the author of the bestseller, The Threat: How the FBI Protects America in the Age of Terror and Trump (2019).
