Ok, turns out if I had been paying more attention I probably could have listened to yesterday's Senate Armed Services Committee hearing. I am on the CSpan web page all the time but I've never noticed the CapitolHearing link at bottom. It allows you to listen to selected hearing as they happen. Oh well, store that away for the future.
I spoke with someone in the Senate Armed Services Committee and they said they put the feed out there and it's up to CSpan when they want to broadcast it. It may replay over the weekend, I'll keep my eye on it.
