"President Barack Obama walks back down the Cross Hall after making a televised statement on the death of Osama bin Laden from the East Room of the White House in Washington, Sunday, May 1, 2011."
False! Actually the Associated Press photos with this caption, and similar captions were taken in a staged session after Obama's announcements. Reuters White House photographer Jason Reed reported that photographers were kept out of the room until Obama finished his announcement.
As President Obama continued his nine-minute address in front of just one main network camera, the photographers were held outside the room by staff and asked to remain completely silent. Once Obama was off the air, we were escorted in front of that teleprompter and the President then re-enacted the walk-out and first 30 seconds of the statement for us.
