Richard Perle is one of the most disgraceful A-holes ever to set foot inside the U.S. Department of Defense. I have no idea if he is telling the truth on this one, but Tenet's recollection of what transpired is perfectly in character with Perle.
Remember, this was the moron who called on the Clinton administration to topple Saddam Hussein back in 2000 in response to the attack on the USS Cole -- even though there wasn't a single shred of evidence linking Iraq to that attack.
Amen.
One thing you can count on though--some lefty is checking the air travel records, and if Perle is lying we will all know soon enough. If it drops out of the news and is never heard about again--then Perle is telling the truth and Tenet is lying.
