Steve Clemons of The Washington Note  has a novel idea:
...[F]ascinating that President Bush wants to polygraph for those who leaked on the CIA prisons, and those who exposed the warrantless wiretap program, but not a single member of his staff for exposing Valerie Plame Wilson's secret CIA identity.
According to some inside the intel arena, Valerie Wilson's work had a lot to do with monitoring Iran's nuclear weapons appetite and capabilities and possibly helped feed Iran nuclear technology junk that could distract and complicate Iran's weapons program efforts. If true, this is quite consistent with the Iran Chapter in Jim Risen's new book, State of War.
I'm not going to say anything more here than say that Wilson was "possibly" doing this.
But if this account of Plame-Wilson's activities is true, those who exposed Valerie Plame Wilson helped undermine American national security in much more major ways that haven't yet been disclosed.
Where are the polygraph tests for your staff, Mr. President?
