of the State Dept. document that first identified Plame as a CIA WMD expert. That document, called the INR, was distributed to the circle of those who were trying to get dirt on Ambassador Wilson and his wife, Valerie Plame.
Grossman, who is a lesser known (but important) neo-con, changed the name Valerie Plame to Valerie Wilson on a State Department document that he incorporated into the 7/10/03 "INR" document that Grossman prepared and Armitage faxed to Powell about AF-1. The INR identifying Valerie Plame was then passed around by Bush's aides. Libby requested and received the original document naming Plame in a fax from Grossman before Libby had his famous breakfast meeting with Judy Miller on 7/8.
But, Grossman was responding to an inquiry from Libby who was originally told about Plame by Cheney. So, the chain of custody goes back to you know who, Dick Cheney.
