Cheney's office scents trouble when Niger story is challenged

The role of Cheney's office is important to the story as well, as a Post article reveals today.
"Wilson set out to discredit the charge, working largely through back channels at first to debunk it. He called friends inside the government and the media, and told the New York Times's Nicholas D. Kristof of his findings in Niger. Kristof aired them publicly for the first time in his May 6, 2003, column but did not name Wilson. This caught the attention of officials inside Cheney's office, as well as others involved in war planning, according to people who had talked with them."
