President Obama was literally pulled from a golf outing and escorted back to the White House to be informed of the mission. Upon his arrival there was a briefing held which included Bill Daley, John Brennan, and a high ranking member of the military. When Obama emerged from the briefing, he was described as looking "very confused and uncertain." The president was then placed in the situation room where several of the players in this event had already been watching the operation unfold. Another interesting tidbit regarding this is that the Vice President was already "up to speed" on the operation. A source indicated they believe Hillary Clinton had personally made certain the Vice President was made aware of that day's events before the president was. The now famous photo released shows the particulars of that of that room and its occupants. What that photo does not communicate directly is that the military personnel present in that room during the operation unfolding, deferred to either Hillary Clinton or Robert Gates. The president's role was minimal, including their acknowledging of his presence in the room.
This is from that article I couldn't find a few days ago. As I said, there was no corroboration of this story at the time, it was written anonymously, quoted an anonymous source who cited other anonymous sources, and then I lost track of it. But it's a very interesting read
It will be even more interesting to see, when Richard Miniter's Leading From Behind: The Reluctant President and the Advisors Who Decide for Him
hits the stores this week, how closely his story tracks this one.
