If the exchange posted there happened, that is one damn bizarre and cryptic exchange in my book! I'm curious as to your take on it.
I find it amusing that he cites "classified information" as though that's sacred to him, as the Leaky one has never let that stop him from spilling the beans in the past.
It happened. It's available for viewing on CSPAN. Look for "Senate Judiciary Cmte. on DoJ Oversight (July 9, 2008)." It is at the 2 hour and 34 minute mark into the 2 hour and 38 minute session.
My take on it is as always: The Amerithrax investigation is an ongoing case, and details cannot be publicly discussed.
