In July 2005, several months prior to her October 2005 resignation from "The New York Times", Miller was jailed for contempt of court for refusing to testify before a federal grand jury investigating a leak naming Valerie Plame as a CIA officer. While Miller never wrote about Plame, she was believed to be in possession of evidence relevant to the leak investigation. According to a subpoena, Miller met with an unnamed government official, later revealed to be I. Lewis "Scooter" Libby, Vice President Dick Cheney's Chief of Staff, on July 8, 2003. Plame's CIA identity was divulged publicly in a column by conservative political commentator Robert Novak on July 14, 2003. Novak's source was revealed to have not been Libby, but Richard Armitage of the Department of State.
