WAPO puts the 6/10/03 INR memo in a meeting at the WH in June 03.
From the Pincus 10/18/05 WAPO article.
Senior administration officials said there was a document circulated at the State Department -- before Libby talked to Miller -- that mentioned Plame. It was drafted in June as an administrative letter and addressed to then-Undersecretary of State Marc Grossman, who was acting secretary at the time since Secretary of State Colin L. Powell and Deputy Secretary Richard L. Armitage were out of the country.
As a former State Department official involved in the process recalled it, Grossman wanted the letter as background for a meeting at the White House, where the discussion was focused on then growing criticism of Bush's inclusion in his January State of the Union speech of the allegation that Hussein had been seeking uranium from Niger.
To clear up any questions as to why this quote says letter instead of memo, the WAPO also has this
The letter to Grossman....It had a paragraph near the beginning, marked "(S)," meaning it was classified secret, describing a meeting at the CIA in February 2002, attended by another INR analyst, where Plame introduced her husband as the person who was to go to Niger...
This section of the article starts with "a document circulated at the State Department". The article goes on to say that the INR anayist's meeting notes are attached. This describes the known contents of the INR memo. The article refers to the INR memo in the next paragraph.
Fitzgerald has questioned several witnesses from the CIA and State Department before the grand jury about the INR memo, according to lawyers familiar with the case.
WAPO says it is not clear whether the memo was discussed at the WH meeting that Grossman attended with the memo.
and it is not clear whether he talked about it at the White House meeting he was said to have attended, according to the former State official.
One more point of interest, a former intelligence official reviewed the INR memo in the summer of 2003. Maybe at the Senate Hearings?
