CLEAN: Chicago seeks Olympic glory in 2016

Chicago is making a strong case to host the 2016 Summer Games, backed by an endorsement from U.S. President Barack Obama. He promises that Chicago will make America proud if chosen. The city plans to minimize environmental impact by utilizing existing sports complexes and temporary venues. However, a local poll indicates that 45% of Chicagoans oppose the idea. If successful, it would be Chicago's first time hosting the Olympics and the ninth time the Games are held in the United States.
