Novak Tells (Almost) All:

This morning's Robert Novak column begins:

Special Prosecutor Patrick Fitzgerald has informed my attorneys that, after 2-1/2 years, his investigation of the CIA leak case concerning matters directly relating to me has been concluded. That frees me to reveal my role in the federal inquiry that, at the request of Fitzgerald, I have kept secret.
With that, Novak proceeds to explain his role in the Wilson-Plame affair, including the identities of two of his three sources (Karl Rove and Bill Harlow). Novak does not reveal the identity of his "primary source," however, though he says Fitzgerald knows who it is.

The Washington Post covers Novak's disclosures here. For more, Novak will discuss these issues in further detail tonight on FoxNews "Special Report" at 6pm.

UPDATE: Tom Maguire has more, including a back check.
