Pete Souza is never far behind President Obama. In fact, sometimes he's ahead of him. As the President's chief White House photographer, Souza is the President's shadow. With unprecedented access, National Geographic follows the President's photographer inside the Obama White House; aboard Air Force One, backstage at the State of the Union, and into the heart of the West Wing. It's a behind-the-scenes look at the everyday grit of the American presidency and a chance to see what it's like to cover the most powerful man in the world; for history.
