Just in case you can't view the YouTube clip in the post below, Allahpundit has the transcript.
[Cheney chief of staff David] Addington told [Democratic Rep. Bill] Delahunt he couldn’t discuss specific techniques being used, or even discussed for use, by CIA agents because terrorists may be watching his appearance and would gain insight into what U.S. intelligence agents are up to.
“You kind of communicate with Al Qaeda if you do. I can’t talk to you because Al Qaeda may watch C-SPAN,” Addington said.
Delahunt responded: “I’m sure they are watching. I’m glad they finally have a chance to see you, Mr. Addington, given your penchant for being unobtrusive.”
