Ah, now I see your confusion.
(U) On February 26, 2002, the former ambassador arrived in Niger. He told Committee staff that he first met with Ambassador Owens-Kirkpatrick to discuss his upcoming meetings. Ambassador Owens-Kirkpatrick asked him not to meet with current Nigerien officials because she believed it might complicate her continuing diplomatic efforts with them on the uranium issue. The former ambassador agreed to restrict his meetings to former officials and the private sector.
( ) The former ambassador told Committee staff that he met with the former Nigerien Prime Minister, the former Minister of Mines and Energy, and other business contacts. At the end of his visit, he debriefed Ambassador Owens-Kirkpatrick , Chad. He told Committee staff that he had told both U.S. officials he thought there was "nothing to the story." Ambassador Owens-Kirkpatrick told Committee staff she recalled the former ambassador saying "he had reached the same conclusions that the embassy had reached, that it was highly unlikely that anything was going on."
(U) On March 1, 2002, INR published an intelligence assessment, Niger: Sale of Uranium to Iraq Is Unlikely. The INR analyst who drafted the assessment told Committee staff that he had been told that the piece was in response to interest from the Vice President's office in the alleged Iraq-Niger uranium deal. The assessment reiterated 1NR's view that France controlled the uranium industry and "would take action to block a sale of the kind alleged in a CIA report of questionable credibility from a foreign government service." The assessment added that "some officials may have conspired for individual gain to arrange a uranium sale," but considered President Tandja's government unlikely to risk relations with the U.S. and other key aid donors. In a written response to a question from Committee staff on this matter, the Department of State said the assessment was distributed through the routine distribution process in which intelligence documents are delivered to the White House situation room, but State did not provide the assessment directly to the Vice President in a special delivery.
So, we have Wilson going to Niger, and stating to officials that 'there was nothing going on'.
( ) In early March 2002, the Vice President asked his morning briefer for an update on the Niger uranium issue. In response, on March 5, 2002, WINPAC analysts sent an analytic update to the briefer which noted that the government of Niger said it was making all efforts to ensure that its uranium would be used for only peaceful purposes. The update said the foreign government service that provided the original report "was unable to provide new information, but continues to assess that its source is reliable." The update also noted that the CIA would "be debriefing a source who may have information related to the alleged sale on March 5."
(U) Later that day, two CIA DO officers debriefed the former ambassador who had returned from Niger the previous day. The debriefing took place in the former ambassador's home and although his wife was there, according to the reports officer, she acted as a hostess and did not participate in the debrief. Based on information provided verbally by the former ambassador, the DO case officer wrote a draft intelligence report and sent it to the DO reports officer who added additional relevant information from his notes.
(U) The intelligence report based on the former ambassador's trip was disseminated on March 8, 2002.
(U) In an interview with Committee staff, the former ambassador was able to provide more information about the meeting between former Prime Minister Mayaki and the Iraqi delegation. The former ambassador said that Mayaki did meet with the Iraqi delegation but never discussed what was meant by "expanding commercial relations."The former ambassador said that because Mayaki was wary of discussing any trade issues with a country under United Nations (UN) sanctions, he made a successful effort to steer the conversation away from a discussion of trade with the Iraqi delegation.
( )When the former ambassador spoke to Committee staff, his description of his findings differed from the DO intelligence report and his account of information provided to him by the CIA differed from the CIA officials' accounts in some respects.
So you have taken the obvious tack that Wilson lied to the CIA. It seems more logical, given that the DO officers added 'additional relevant information' to his briefing, that the DO officers instead reported incorrectly. After all, Wilson had a known history as an administration official going all the way back to Bush I, and no red flags were ever raised - however, you had CIA being repeatedly visited by Cheney, Libby, and other administration officials in a way that the Washington Post reported, some analysts felt 'pressured to make their assessments on Iraq fit with Bush Administration policy objectives'.
Further, if you remember your history of the NIE, you'll note that while the NIE was presented to the Select Committee, members of Congress not on the committee may or may not have had security clearances to view the classified NIE - therefore, they could not read the 'classified' INR and see the doubts on the yellowcake issue - they could, and most did, rely on the declassified five page 'Key Judgements', which contained nothing about yellowcake anyways. Members of the Select Committee could not even transmit knowlege of any classified dissent in the document to members who did not have security clearances (much like Rockefeller in the domestic spying case).
You'll remember when refighting THIS battle that Durbin and Graham both repeatedly requested declassification of a larger part of the NIE for the full Congress and that both voted against the war resolution - take from that what you will.
