A) Joseph Wilson (to journalists, lobbyists) October 15, 2003.
B) Knut Royce, Timothy M. Phelps (Newsday) July 22, 2003.
C) Robert Novak (Chicago Sun-Times) July 14, 2003.
D) Lewis Libby (to Judith Miller) July 12, 2003.
E) Unamed Official (to Bob Woodward) mid-June, 2003.
F) Valerie Plame (to Wilson "on third or fourth date") Spring, 1997.
Correct Answer: (F). This information was publicly verified by Joseph Wilson in Vanity Fair, January, 2004.
Note: Valerie Plame was not punished for her intentional and unauthorized disclosure (which might have endangered CIA "assets"); Joseph Wilson was not punished for failing to report Plame's violation, even though his failure to act violated the terms of the security clearance that he held at the time.
