Notice how nervous David Boren was yesterday in the news conference. I don't think he was telling the whole truth and was definately witholding information. Also, don't forget Boren still has close ties to the Intel community from his days as a US Senator.
Boren is said to be "recuperating"--although I never heard from what. So it might have been nervousness, or maybe he just felt lousy.
Don't forget that David Boren is George Tenent's mentor too!
