Obama is set to address his supporters from Chicago's Grant Park.
Sen. Joe Biden of Delaware will be accompanying Obama to the White House as his vice president. Biden made his first unsuccessful bid for president in 1988, and again this year before dropping out. A six-term senator, Biden is the chairman of the powerful Senate Foreign Relations Committee. One of his adult sons from his first marriage is currently serving in Iraq.
On June 4, Obama won the Democratic presidential nomination, beating Sen. Hillary Clinton in a tight primary race. The 47-year-old Democratic senator from Illinois stepped into the national spotlight in 2004, delivering the keynote address at the Democratic National Convention.
By now, Obama's personal history is well-known: He was born in Hawaii, the son of a white mother and Kenyan father. Obama's father returned to Kenya when Obama was two years old, leaving him to be raised by his mother and her family, including his beloved grandmother, "Toot," who died one day before her grandson was elected one of the most powerful leaders in the world.
After graduating from Columbia University, he went to Harvard Law School, becoming the first African American president of the prestigious Harvard Law Review. He was elected to the U.S. Senate in 2004, where he sits on several committees, including Foreign Relations, Homeland Security and Veterans' Affairs.
