(NECN/NBC News: Brian Mooar, Washington) - On the National Day of Service, President Obama led by example. He and the first lady volunteered at an elementary school, honoring the life and legacy of Martin Luther King Jr. just like he did before his first inauguration.
"It's a symbol of how our democracy works and how we peacefully transfer power. It should also be an affirmation that we're all in this together," said President Obama.
Not far away, the vice president and a bunch of Bidens helped pack supply kits for members of the U.S. military.
Across the country, an estimated quarter million people did something to help someone else.
As required by the constitution, President Obama will take the oath at the White House Sunday and then again Monday in a grand ceremony at the Capitol.
