From a NY Times article on the Wilson case:
In that article he wrote that he had traveled to Africa in 2002 to explore the accuracy of intelligence reports that suggested Iraq might have tried to purchase uranium ore from Niger. Mr. Wilson said that he had been sent on the trip by the C.I.A. after Mr. Cheney's office raised questions about one such report, but that he found it unlikely that any sale had taken place.
It has been two years now, and the Times still hasn't figure out that "tried to purchase" and "sale had taken place" are two separate things! I guess they don't teach logic at the newspaper of record.
