Olympic Updates

Chicago is making its final presentation before the International Olympic Committee chooses the host of the 2016 Summer Games.

A video rolls showing a crowd of some 200,000 -- young and old, black, white, brown and yellow, gay and straight, men and women -- happily gathered in what is called the city's front yard, Grant Park.

Now the video shows the man they have come to see as he emerges from backstage and he walks out to greet the crowd.
