In his article, Robert Novak says:
Joe Wilson’s wife’s role in instituting her husband’s mission was revealed to me in the middle of a long interview with an official who I have previously said was not a political gunslinger. After the federal investigation was announced, he told me through a third party that the disclosure was inadvertent on his part.
So a better sleuth than I might find out who was being interviewed by Robert Novak right before his June 8, 2003 call to Karl Rove. I tried the Chicago Sun Times and nothing jumped out at me.
Hmmm. A ‘mission’. Will persue. Wonder if we’ll be able to rule out this guy:
