They turned to the hot topic of anthrax. The powder in the letter mailed to Senator Daschle's office had been found to be potent, prompting officials to suggest its source was likely an expert capable of producing the bacteria in large amounts. Tenet said, "I think it's AQ" meaning al Qaeda. "I think there's a state sponsor involved. It's too well thought out, the powder's too well refined. It might be Iraq, it might be Russia, it might be a renegade scientist," perhaps from Iraq or Russia. Scooter Libby, Cheney's chief of staff, said he also thought the anthrax attacks were state sponsored. "We've got to be careful on what we say." It was important not to lay it on anyone now. "If we say it's al Qaeda, a state sponsor may feel safe and then hit us thinking they will have a bye because we'll blame it on al Qaeda."
"I'm not going to talk about a state sponsor," Tenet assured them.
"It's good that we don't," said Cheney, "because we're not ready to do anything about it."
