Michelle Obama to lead Olympic delegation at London Olympics

WASHINGTON (AP/ABC7) - The White House says Michelle Obama will lead the official U.S. delegation to the opening ceremonies of the 2012 Summer Olympic Games in London.

Before she takes on this responsibility, though, the First Lady was joined Tuesday by her British counterpart to take on an athletic endeavor of their own.

On Tuesday, Mrs. Obama and Samantha Cameron, the wife of British Prime Minister David Cameron, held mini-Olympic competition with physical activities for D.C.-area children at American University. The competition is part of her Let's Move! initiative promoting fitness and healthy eating.

Cameron is accompanying her husband on a two-day visit to the United States.

Together, they got 60 elementary school students moving, while being joined by several current and former Olympians and Paralympians, including Kortney Clemons, Dominique Dawes, April Holmes, Lisa Leslie, Lori Ann Lindsey, Dan O'Brien, Becky Sauerbrunn and David Wagner.

It has become somewhat of a tradition for first ladies to lead the U.S. delegation. Laura Bush headed the delegation to the 2006 Winter Olympics in Torino, Italy, and Hillary Rodham Clinton headed up the delegation at the 1994 Winter Olympics in Lillehammer, Norway.
