So you really think they want this hoax to end? If it were to ever end then people would be free to ask who it was that sent Joe Wilson to Niger to pretend to hunt sales of yellowcake.
Right now with the "investigation" still playing out, another grand jury nobody is going to do anything to appear to be obstructing justice except the media who were in on this hoax from the get go.
I think what they should be looking at is:
What role did Valerie play when he got back from Niger. Was he privy to WMD information via Valerie?? that would effect his view. Did she sit in when they interviewed him?
This chick outed herself on their third date AND HE WAS STILL MARRIED bsides.
I wouldn't trust her as an agent if my life depended on it.
During WWII, I think they called these type of "spies" _______________.
