Novak, host Joe Scarborough falsely suggested that White House senior adviser Karl Rove was not involved in leaking the identity of former CIA operative Valerie Plame. On the July 19 edition of the show, on which Novak again appeared, Scarborough claimed that Media Matters was "very upset because of my interview yesterday with Bob Novak, talking about the narrative that the left wing had for a very long time that this whole Valerie Plame leak was a diabolical plot hatched by Karl Rove." Introducing Novak, Scarborough said he was "{h}ere to clear that up and talk about his book, Prince of Darkness" {Crown Forum, July 2007}, and, in fact, in response to questioning from Scarborough, Novak acknowledged that Rove was his confirming source. Nonetheless, the two continued to push the false claim, made frequently by defenders of the administration in the media, that special counsel Patrick J. Fitzgerald -- in Scarborough's words -- "knew that no crime, no underlying crime had been committed" and yet persisted with the investigation that resulted in the conviction of former vice presidential chief of staff I. Lewis "Scooter" Libby for perjury, obstruction of justice, and making false claims.
