Because they are all in on the cabal.
On page 39 of the Senate Committee Report on Niger it says that the Reports Officer testified that the former ambassador's wife recommended her husband name to the Chief of the CPD. That person made the decision to send him. Check the CIA web-site to find out this person's name.
And the irony is that the left is always going after the CIA, the heart of the capitalist empire builders. But now, the CIA is beyond reproach. Russert says on MTP - we should let the CIA determine who is covert and who isn't - like the media never questions what the CIA says.
This whole thing stinks. The CIA/State angle is going to be exposed - the question is when.
