Mr.Gannon is not being truthful when he says he does not know why he is being subpoenaed. When
he interviewed Wilson last October he made reference to "an internal government memo" purporting to be the minutes of a meeting at which Plame played a key role in getting her husband the Niger assignment.
From the interview: TN: An internal government memo prepared by U.S. intelligence personnel details a meeting in early 2002 where your wife, a member of the agency for clandestine service working on Iraqi weapons issues, suggested that you could be sent to investigate the reports. Do you dispute that?
Since the Niger Uranium documents have been judged forgeries, Gannon is suggesting that he was made privy to counterfeit official/government documents which is a crime, and a separate crime at that and logically he would be hauled in front of a grand jury probing the Plame affair.
Your professed insight into the motivation of the Grand Jury is merely guesswork.
The document in question has never been acknowleged by any government agency to even exist.
This is a one-sided investigation where people are being accused of crimes for revealing names and information that may have not been secret in the first place.
