A retired CIA agent who publicly confirmed the torture of al-Qaeda operative Abu Zubaydah has been charged with leaking classified information. John Kiriakou, who served from 1990 to 2004, is best known for a 2007 ABC News interview detailing how Zubaydah was waterboarded in CIA custody. On Monday, Kiriakou was indicted on allegations of revealing the identity of covert officer, leaking classified information and lying to a CIA publications review board. The Justice Department says Kiriakou disclosed the identities of CIA officers involved in Zubaydah’s interrogation to journalists. He is the sixth person the Obama administration has charged under the Espionage Act in its crackdown on government whistleblowers. Kiriakou faces up to 20 years in prison.
