President Obama and first lady Michelle Obama arrive to promote the city of Chicago's candidacy for the 2016 Olympic Games during the International Olympic Committee's 121st session in Copenhagen Oct. 2, 2009. Chicago was among four cities under consideration to host the Olympics, along with Madrid, Tokyo and, the ultimate winner, Rio de Janeiro. The president made a last-minute, whirlwind trip to Copenhagen for the final presentation, to no avail. "One of the things that I think is most valuable about sports is that you can play a great game and still not win," the president told reporters upon returning home. (Pool Photo/Reuters)
