I too find this disturbing. If CIA has gone over to the dark side, Rumsfeld should have had someone from the military intel side of the street in there nosing around. And on something as important as this, the Repub Party organization should have hired some private people to investigate not only the issue itself, but Wilson personally, and Wilson's business and political connections that might shed light on his involvement in this.
They should have taken this dead serious.
I wonder how much influence the State Department has over the investigations of the CIA, such as the needed follow-up on the Niger uranium issues. Remember, the CIA itself is the one whose personnel were going after GWB with leaks to the press. And the CIA requested the investigation into the criminality of the "outing" of Ms. Plame. So I would not say it's the Republicans doing the slow shuffle in failing to get the job completed. I'd say it's the left wingers like Wilson still trying to fulfill their agenda.
