London Olympics 2012: Michelle Obama will lead the official US delegation to the opening ceremonies

The White House has announced today that First Lady Michelle Obama will lead the official U.S. delegation to the opening ceremonies of the 2012 Summer Olympic Games in London.

It has become somewhat of a tradition for first ladies to lead the U.S. delegation.

Laura Bush performed the duty at the 2006 Winter Olympics in Torino, Italy, and Hillary Rodham Clinton headed up the delegation at the 1994 Winter Olympics in Lillehammer, Norway.

The announcement comes during a three-day visit to the U.S. by Prime Minister David Cameron and his wife Samantha Cameron, in which he and President Barack Obama intend to focus on foreign policy issues.

Michelle Obama will host a mini-Olympic competition with physical activities for D.C.-area children at American University today.

The competition is part of her “Let’s Move!” initiative promoting fitness and healthy eating.

Michelle Obama will be joined by Samantha Cameron.

Olympians and Paralympians expected to attend the event include: Kortney Clemons, Dominique Dawes, April Holmes, Lisa Leslie, Lori Ann Lindsey, Dan O’Brien, Becky Sauerbrunn and David Wagner.

The Olympics opening ceremony will take place in London on July 27.
