On his third question, Leahy asked Mukasey to clarify a recent comment he made in San Francisco where he implied that the failure to listen in on a phone call from Afghanistan to the United States prior to the Sept. 11, 2001 attacks had cost 3,000 lives.

"Nobody else seems to know about this. Can you tell me what the circumstances were and why?" Leahy said.

"The phone call I referenced relates to an incoming call that is referred to in a letter in February of this year to House Intelligence Committee Chairman [Silvestre] Reyes [(D-Texas)] from Director of National Intelligence Mike McConnell and I," Mukasey said.

"One thing I got wrong. It didn't come from Afghanistan. I got the country wrong," Mukasey continued without specifying the country where the call originated.

"No FISA [Foreign Intelligence Surveillance Act] application should have been necessary to monitor a foreign target in a foreign country," Leahy reminded Mukasey. "We didn't need it then. And we didn't need it today."
