After President Obama is sworn in today, he will attend a congressional luncheon and then, at around 2 p.m. ET, the president and his family will set off for the inaugural parade from the Capitol to the White House.
Following the route charted by Thomas Jefferson more than 200 years ago, Mr. and Mrs. Obama will travel alongside floats and vehicles from various walks of life until they arrive at the White House. At some point, they'll probably also follow a more recent tradition -- which started with former President Jimmy Carter -- of ditching their ride for at least part of the journey and making the walk on foot.
The full list of participants in the parade can be found here.
In addition, there will be eight floats, according to the Presidential Inaugural Committee:
The Hawaii State Float: Hawaii is the birthplace of President Obama. The float features a large volcano modeled after the famous Diamond Head Volcano and a tribute to the late Senator Daniel Inouye.
The Illinois State Float: Illinois is the birthplace of First Lady Michelle Obama. The float features American flags, the state flag and a panorama of the Capitol.
The Pennsylvania State Float: Pennsylvania is the birthplace of Vice President Joe Biden. The float includes a replica of the Liberty Bell and the Pennsylvania State Seal.
The Delaware State Float: Delaware is the home state of Vice President Joe Biden and Jill Biden. The float includes a replica of State Capitol Bell Tower.
The Martin Luther King, Jr. Float: The float's design features an image of Dr. King and a representation of his quote "out of the mountain of despair a stone of hope."
The Civil Rights Movements Float: The Civil Rights float features images representing historic struggles of many of the civil rights movements in our country. The images represented include Immigration, Women's, LGBT, Civil and Labor Rights. The float also includes Martin Luther King's quote "The Arc of the moral universe is long but it bends toward justice."
The Tuskegee Airmen Float: The float is a tribute to the brave young men who were the first African-American military aviators in the United States Armed Forces. The float features a model North American P-51 Mustang.
The Inaugural Theme, "Our People. Our Future." Float: The American people are the focus of this float. Riding on the float are the citizen co-chairs for the National Day of Service.
