"Former vice president Dick Cheney told a special prosecutor in 2004 that he had no idea who leaked the identity of CIA agent Valerie Plame, according to newly released FBI documents.
Cheney was questioned as part of an investigation on how journalists came to know the identity of Plame, the wife of former Ambassador Joseph Wilson, who was a critic of the Iraq war.
In the interview, Cheney responded to many questions with "I do not recall."
