Year in Photos by White House Photographer Pete Souza

White House Photographer Pete Souza shares moments from President Barack Obama's first year in office. See the complete set here. I selected a few photos below.

Jan. 20, 2009. “President-elect Barack Obama was about to walk out to take the oath of office. Backstage at the U.S. Capitol, he took one last look at his appearance in the mirror.” (Official White House photo by Pete Souza)

Feb. 2, 2009. “White House valets had moved the sofas in the Oval Office to accommodate the large number of press photographers that were covering the President’s meeting with Vermont Gov. Jim Douglas. When the photo-op ended, the President said to Gov. Douglas, ‘let’s move the sofas back in place.’ Gov. Douglas didn’t quite know what to do as the President did the heavy lifting. The valets now good-naturedly cringe when they look at this picture because it was their responsibility to move the sofas back in place.” (Official White House photo by Pete Souza)

Feb. 4, 2009. “The President talks with aides during an impromptu meeting around the Resolute desk.” (Official White House photo by Pete Souza)

Feb. 26, 2009. "The President walks alone along the White House Colonnade to the Oval Office late one night. He tells people that he likes having his ‘home office’ so close to where he lives." (Official White House photo by Pete Souza)

March 9, 2009. “To appreciate this photograph, one must know the iconic photograph by Stanley Tretick of John Kennedy Jr. crawling out from the trap door of this same desk while his father, President Kennedy, worked at the desk. Caroline Kennedy had stopped by to see President Obama, and when she mentioned that he was using the same desk as her father, the President immediately remembered the Tretick picture and tried to open the trap door. It was locked and no one had a key.” (Official White House photo by Pete Souza)

March 15, 2009. “The Obama family was introduced to a prospective family dog at a secret greet on a Sunday. After spending about an hour with him, the family decided he was the one. Here, the dog ran alongside the President in an East Wing hallway. The dog returned to his trainer while the Obama’s embarked on their first international trip. I had to keep these photos secret until a few weeks later, when the dog was brought ‘home’ to the White House and introduced to the world as Bo.” (Official White House photo by Pete Souza)

Jan. 16, 2010. “President Obama had called on the two former Presidents to help with the situation in Haiti. During their public remarks in the Rose Garden, President Clinton had said about President Bush, ‘I’ve already figured out how I can get him to do some things that he didn’t sign on for.’ Later, back in the Oval, President Bush is jokingly asking President Clinton what were those things he had in mind.” (Official White House photo by Pete Souza)
