WASHINGTON - On Monday, January 21, 2013, Barack Obama was sworn in as America's 44th president.
A wistful moment for the president came shortly after his public swearing-in ceremony.
As he began walking off the inaugural platform to go into the U.S. Capitol for the traditional luncheon with lawmakers and other dignitaries, Obama stopped and turned around to look at the scene on the National Mall, filled with hundreds of thousands of people who braved chilly weather to be part of the day.
"I want to take a look, one more time," he said. "I'm not going to see this again."
