Washington, DC (My Sportsbook) - President Barack Obama will join the United States' delegation in Copenhagen this week in an effort to help Chicago land the 2016 Olympics.

The International Olympic Committee will vote to select a host city on October 2. The finalists in competition with Chicago are Rio de Janeiro, Madrid and Tokyo.

First Lady Michelle Obama is leading the U.S. contingent and is slated to arrive in Copenhagen on Wednesday. The President is set to arrive on Friday morning and is expected to leave later that day.

According to the White House, the President and First Lady will both make presentations to the IOC during Friday's session.

The close ties the Obamas have to Chicago could be a difference maker. The President worked as a civil rights attorney in the Windy City before going into politics and spent four years as a U.S. Senator prior to winning the presidency in 2008. Mrs. Obama was born and grew up on the South Side of Chicago.

President Obama had indicated that he would not travel to Copenhagen because of his priority to pass health care reform in the United States.
