Thanks, The Source of the forgeries and why Wilson spoke of seeing them when he couldn't have is one of the remaining mysteries, isn't it, fedora? Like you I've a number of good ideas but no proof.
Yes, the new SSCI report says on pdf p. 56 that the FBI is still investigating the origin of the forgeries. Another unresolved question is who first advised the IAEA of the forgeries--my summary of the various discrepancies surrounding this issue:
Wilsongate: Motive, Means, and Opportunity
On February 4, the day before Powell’s UN speech, someone briefed Baute on the Niger forgeries and provided him with copies. Who provided the briefing and forgeries to him and where they did so have been reportedly differently by different sources. According to Baute’s account as reported by Seymour Hersh, he was briefed by the US mission in Austria while aboard a plane en route from IAEA headquarters in Vienna to UN headquarters in New York, and upon reaching New York he was provided with copies of the documents by the US.174 What the Senate Select Committee on Intelligence’s report says regarding this is censored at a key point, reading, “On February 4, 2003, the U.S. Government passed electronic copies of the Iraq-Niger documents to [3/4 line deleted] the IAEA. Because the Director of the IAEA’s INVO [Iraq Nuclear Verification Office] was in New York at the time, the U.S. Government also provided the documents to him in New York.”175 So far this seems consistent enough. But slightly at variance with these accounts is a July 18, 2003 article by Walter Pincus and Dana Priest which depicts the briefing occurring in Vienna rather than on the plane from Vienna: “On Feb. 4, the U.N. inspectors' Iraq team was called to the U.S. mission in Vienna and verbally briefed on the contents of the documents. A day later, they received copies, according to officials familiar with the inspectors' work.” A couple weeks earlier, Pincus and Richard Leiby had reported that the copies of the forgeries the inspectors received came from the CIA: “In early February, the CIA received a translation of the Niger documents and in early March, copies of the documents, which it turned over to the International Atomic Energy Agency.”176 A seemingly different account is found in a March 8, 2003 article by Ian Traynor, stating that Britain provided the documents to the IAEA in Vienna: “British officials named the state of Niger as the source of the uranium and passed their evidence to the UN nuclear watchdog, the international atomic energy agency, in Vienna.” Hans Blix curiously stated as reported in an April 22, 2003 article by Sally Bolton, “The CIA say they got a copy of the document from the UK.”177 This is contradicted by a September 2003 British Parliamentary investigation which states, “In February 2003 the International Atomic Energy Authority (IAEA) received from a third party (not the UK) documents that the party had acquired in the autumn of 2002 and which purported to be evidence of Iraq’s attempts to obtain uranium from Niger. In March 2003 the IAEA identified some of the documents it had received as forgeries and called into question the authenticity of the others.” Britain’s July 2004 Butler Report similarly though somewhat more vaguely states: “it was not until early 2003 that the British Government became aware that the US (and other states) had received from a journalistic source a number of documents alleged to cover the Iraqi procurement of uranium from Niger. Those documents were passed to the IAEA. . .”178
