Missed this. I was in town but having lunch with a friend. Could have had some fun video for you. I have this though, which gives you a pretty good idea of what went on.
I like Mark Knoller of CBS, the big guy in the white shirt, who chronicles the White House via Twitter. Looks he’s taking his time getting out while working on some tweets.
It appears a bomb threat targeting the briefing room had been phoned in to the Washington police. The all-clear was given about 20 minutes later and reporters filed back in.
