Several people present in that room report that the opportunity to get bin Laden was almost missed, because Obama wasn't even in the building. They had to chase him down on the golf course, and drag his butt back to the White House, in order to get the go-ahead to launch the operation.
As you can see from his expression, Obama was hearing about this "bin Laden operation" for the first time.
Obama calls this "leading from behind", or "leading with his behind", or something like that.
McKayla confirms this report. She had places to go, and things to do, and she was sick of waiting around for Obama.
