We should start calling this the "Valerie Plame Report to Congress on Iraq WMD".
SHe is a senior expert on WMD and most likely had a lot of influence in its tone and content. She was obviously asked who to send to Niger to investigate Iraq connection to Yellow Cake and that recommendation was taken. She was the "go to" person in the CIA when it came to Iraq and WMD.
That is indeed an interesting question - did she have a hand in crafting this report or any other like it? Hmm...
