Joe Wilson was going to Niger on private company business. His wife arranged for an 'all expenses paid, no strings attached' trip for Joe, on the CIA's ticket, to 'spy' for them to see if Saddam was buying Yellowcake from the President Of Niger.
What was Joe's private company in the business of? In Niger?
You thinking along the same lines as I am. Joe Wilson made a lot of money being a consultant to business interests in Africa. I wonder if Wilsons business connections in Niger and Africa led him to lie about Nigers yellowcake production.
