Top Bush FBI international terrorism official turning into another Brownie?

From Reuters:

The FBI official in charge of international terrorism before September 11 said on Tuesday he did not know an agent had warned three weeks before the hijackings that he suspected Zacarias Moussaoui was plotting a terrorist act....

[the FBI agent who arrested Moussaoui told officials three weeks before the attack that he] believed Moussaoui was a Muslim fundamentalist who was learning to fly a jumbo jet, and that the agent believed he was a terrorist who could be possibly planning a hijacking.
