U.S. President Barack Obama (R) salutes to a
Marine officer by the Marine One prior to his departure from the White
House February 10, 2009 in Washington, DC. Obama was travelling to Ft.
Myers, Florida, for a town hall meeting to discuss his economic
stimulus package. (Photo by Alex Wong/Getty Images)
Update: A commenter and an email say this Marine is not an officer. But blame the Getty photo people, who provide the captions posted with these pictures.
