John Kiriakou

John C. Kiriakou, the first C.I.A. officer to be imprisoned for leaking classified information to a reporter, was released to home confinement February 2015 after serving nearly two years in federal prison in Pennsylvania. Kiriakou worked from 1990 to 2004 as a C.I.A. analyst and a counterterrorism officer, including in Pakistan after the Sept. 11, 2001, terrorist attacks. He helped lead the operation that captured Abu Zubaydah, who helped run a training camp for Al Qaeda fighters and other militants, and whose detention after a shootout in Pakistan was hailed as the agency’s first big success after Sept. 11. Mr. Kiriakou described the episode in a 2012 memoir, “The Reluctant Spy: My Secret Life in the C.I.A.’s War on Terror.” He was charged in 2012 with disclosing classified information to journalists. Mr. Kiriakou was sentenced to 30 months in prison and sent to a low-security prison through a plea agreement.
