Obama said his favorite story from the Olympics was that of sprinter Manteo Mitchell, who broke his left fibula halfway through a 4-by-400 relay but finished the race, helping his team qualify for the finals. The United States ultimately took home the silver medal.
Obama also mentioned that he stopped by the Olympic training facilities on a campaign visit to Colorado Springs, Colo., earlier this year. Obama is statistically tied with Mitt Romney in the critical battleground state of Colorado.
"All of you have stories of determination and perseverance and all of you made incredible sacrifices to get here,” Obama said. “You gave us a summer we will never forget.”
Swimmer Michael Phelps tweeted his excitement ahead of the event.
