President Obama will personally lobby the International Olympic Committee to bring the games to Chicago in 2016.
The president and the first lady will travel to Copenhagen, Denmark on Thursday to make the pitch to the committee as they decide on a host city for the games.
The White House issued a statement saying the Obamas "will both make presentations to the IOC during Friday's session. They will discuss why Chicago is best to host the 2016 Summer Games, and how the United States is eager to bring the world together to celebrate the ideals of the Olympic movement."
Obama, who is from Chicago, will be the first U.S. president to take such a direct role in lobbying for the Olympics.
"President Obama and First Lady Michelle Obama symbolize the hope, opportunity and inspiration that makes Chicago great, and we are honored to have two of our city's most accomplished residents leading our delegation in Copenhagen," Mayor Richard M. Daley said in a statement.
"Who better to share with members of the International Olympic Committee the commitment and enthusiasm Chicago has for the Olympic and Paralympic Movement than the President and First Lady," he added.
Rio de Janeiro, Madrid, and Tokyo are the other cities on the list to be host cities.
The heads of state of Brazil and Spain will also travel to Copenhagen on behalf of their cities, and the IOC is scheduled to decide the site on Friday.
