4 of 4
U.S. President Barack Obama arrives in Copenhagen to promote Chicago's bid to host the 2016 Summer Olympic Games October 1, 2009. No incumbent U.S. President has ever addressed an IOC session before. Over 100 IOC members have gathered here to choose between the rival bids of Chicago, Madrid, Rio de Janeiro and Tokyo for the 2016 games. The four candidate cities for the 2016 Olympics were preparing to put closing arguments to one of the world's most exclusive group of voters on Friday, with Obama lined up as the main draw.
