Check out this very nice scoop from Newsweek's Hosenball and Isikoff about a June 2002 Iraqi National Congress memo pointing to John Hannah and Bill Luti as the conduits through which the INC filtered its 'intelligence' to the Vice President's office and the Doug Feith's operation at the Pentagon, respectively.

Frankly, this is only a scoop in the sense that there seems to be documentation (and that's definitely a scoop). I don't think you could find anyone who's covered this story who wouldn't be shocked if these conduits didn't exist. And Hannah and Luti would be logical channels.

The official denials noted in the story really don't pass the laugh test.
