Speeches, parades, balls
Obama has been crafting his inaugural address for weeks, scrawling out drafts on yellow legal pads. This weekend, he faces the task of juggling speech preparations and his presidential duties, including briefings on the fate of Americans and others caught up in a still-unfolding hostage crisis at a desert gas plant in Algeria.
While second inauguration speeches rarely go down in history, Monday's address is a rare opportunity to face millions of television viewers and seek support for upcoming fights with the men and women who work in the Capitol building behind the podium where he will speak.
"This time it's scaled down, but it's still historic for all of America," said Courtney Prater, a construction worker visiting from Detroit, after a tour of the White House.
The White House views the two speeches - he delivers his State of the Union address before Congress on Feb 12 - as two parts of a package, with the first one spelling out a vision and the second one specific policy proposals.
"The president, I think, is very appreciative of the fact that the American people have given him this opportunity to deliver a second inaugural address," White House spokesman Jay Carney told reporters this week.
"He believes that we have work to do, and he believes that both the agenda he has put forward so far and the agenda he will put forward in the future will help this country move forward in a variety of ways," Carney said.
After lambasting Republican opponent Mitt Romney during the presidential campaign for remarks that dismissed nearly half of the US electorate, Obama is likely to offer some words of humility and resolve to represent even those who did not vote for him last year.
After the speech, Obama and his wife, Michelle, will join Vice President Joe Biden and his wife, Jill, at a luncheon at the capitol. Later the two couples will take part in the inaugural parade, returning to the White House in a motorcade and likely getting out to walk part of the way, waving at the crowd and surrounded by Secret Service members.
For weeks, workers have been building viewing stands along the parade route for visitors.
After seeing the rest of the parade from a spot in front of the White House, the Obamas will attend two official inaugural balls, dancing for the cameras and, in the first lady's case, donning a gown that will be scrutinized closely for its style and fashion sense.
