Abu Zubaydah was subjected to both traditional interrogations and waterboarding. FBI agents who conducted the traditional interrogations say the waterboarding and other aggressive tactics were ineffective.
Kiriakou did not participate in Abu Zubaydah’s waterboarding.
Under the deal with prosecutors, Kiriakou pleaded guilty last October to leaking the identity of one of the agency’s covert operatives to a reporter. Prosecutors dropped charges brought under the World War I-era Espionage Act. They also dropped a count of making false statements.
