President Barack Obama has exited his limousine for the traditional presidential walk in the inaugural parade from Capitol Hill to the White House.
Obama and first lady Michelle Obama waved to cheering, flag-waving crowds lining Pennsylvania Avenue to celebrate the start of Obama's second term.
Obama, Vice President Joe Biden and their families were among more than 8,800 people, floats and marching bands participating in the late-starting parade that passed before viewing stands and bleachers after Obama's public swearing-in ceremony.
Thousands of people had waited in security lines that stretched a block to gain access to parade-viewing spots accessible to the general public without a special ticket.
Spectators wore Obama t-shirts, ski caps, hoodies and buttons, and one woman wrapped herself in an Obama beach towel for extra warmth.
President Barack Obama says it was a privilege to take the oath of office using a Bible that had been owned by the Rev. Martin Luther King Jr.
Obama paused by a statue of King in the Capitol Rotunda after a luncheon hosted by members of Congress. He was accompanied by his wife, Michelle, and Vice President Joe Biden and his wife, Jill.
"You know this is the first time I have seen this," he said.
King's Bible was one of two he used for the ceremonial inauguration.
"I had the great privilege that the Bible we used was his Bible and they asked for it to be inscribed," Obama said. The other Bible belonged to President Abraham Lincoln.
Monday was the federal celebration of King's birthday.
President Barack Obama's inauguration Monday brought out a festive crowd of flag-wavers who filled the National Mall to overflowing, hailed his moment with lusty cheers and spent their down time spotting celebrities amid the bunting.
The celebration couldn't quite match the huge crowds and adrenaline-pumping energy of Obama's first inaugural on the West Front of the Capitol. But it was a lively second act.
