Why wasn't George Tenet fired?

I have no context to place this in that makes sense to me. Why would the CIA, with what appeared to be seriously inside-information about Saddam's WMD seemingly pay no attention to it? Especially if-as reported by some-the bureaucracy itself was chafing at the White House's characterizations about Saddam's capabilities. I'm perplexed.

Why would they have talked to Sabri and done nothing with it? The only conclusions I can reach, at this point anyway, are that they thought Sabri was full of it or they completely missed the importance of what they got.

NRO's Media Blog thinks it's an easy call:

The story essentially defuses itself later on:

The U.S. hoped Sabri would leave Iraq and publicly renounce Saddam. He repeatedly refused, sources say, and contact was broken off.

It's obvious why the CIA dismissed the information he was providing: This man was obviously loyal to Saddam. NBC is suggesting that proper protocol for the U.S. should have been to ignore British, French, Russian, and our own intelligence agencies, and instead rely on a member of Saddam's inner circle.

Neither of those options are necessarily very reassuring.
