a brief history, with links.
Ambassador Wilson was asked by someone under Cheney to find out if the "purchased yellow cake uranium" claim that Bush wanted to put in his state of the union address was true.
Wilson went to Niger and looked at the financial records for yellow cake purchases and other factors and determined that Saddam had not purchased yellow cake uranium from Niger. (the Niger uranium is controlled by a consortium of western countries, led by France, and the International Atomic Energy people keep track of what's going on as well...they also determined the claim was not true.)
Nevertheless, Bush included this claim in his speech to convince Americans that Saddam was a imminent threat to American's safety. This was a lie.
Wilson wrote an editorial in the New York Times which revealed that he had given this information to persons under Cheney's command, and therefore Bush et all should have known this issue was not one which they could use to justify an invasion of Iraq, and to do so was to lie to the American people.
After some media coverage of this issue, Novak, in his column for the Chicago Sun, wrote that Wilson's wife, Valerie Plame, got Wilson the job of finding info on Niger, and that she was, in fact, a CIA operative. Novak claimed this came from two White House Officials..which means it came from high up in the Bush administration. The White House, in other words, was trying to smear Wilson's credibility by insinuating that his wife got him the job, therefore his info was unreliable...uh, okay.
David Corn wrote about Novak's article in The Nation and noted that Novak was protected even though he may have outed a CIA agent because he's a journalist and did not display a pattern of willfully outing agents.
However, the persons in the White House who ratted out Plame WERE guilty of high crimes, and a violation of the Identities Protection Act, which was passed back when Frank Church, a democrat, was initially charged with outing an agent. Bush I himself claimed this was false, but the Republicans jumped all over this issue when Church and others were investigating the illegal and unconstitutional activities of the Reagan Administration and their use of the CIA during Iran/Contra and other nasty pieces of work.
This was picked up by Time and Newsday. Bloggers were all over it. The Seattle Post-Intelligencer called it a "cancer in the White House."
Wilson has been interviewed in various media about the issue. He frames it as an attempt to put fear into anyone else who would try to tell the truth when the Bushies want to hide their illegal actions, and therefore a dangerous precedent.
This pretty much brings us up to this weekend when, on Friday, CNBC revealed the CIA thinks their was illegal action. Now Ashcroft has to decide if outing a CIA agent is worse than Tommy Chong selling a bong. If he decides this is so, the FBI will investigate.
I strongly suggest you follow the links and read Josh Marshall's talkingpointsmemo for what's going on now, and for an EXCELLENT (and long) interview with Wilson on these issues.
