Dec. 16, 2012 "The President works on his Newtown speech at an auditorium in suburban Washington. Two days earlier, I had photographed him when John Brennan first briefed him on the shootings. Throughout that day, he reacted as we all did, which people witnessed when he delivered his statement a few hours later. Before we headed to Newtown for the Sunday night vigil, he went to watch his daughter Sasha, 11, at her rehearsal for the Nutcracker; he would be unable to attend her performance because of the trip to Newtown. During breaks in the rehearsal, he worked on his speech. His expression in this photograph may be subtle to the viewer, but not to me. There is emotion and resolve etched on his face, and he knew the importance of this speech for the nation." (Pete Souza/ PSG)
