The White House has announced that First Lady Michelle Obama will lead the U.S. delegation to the opening ceremonies of the 2012 Summer Olympic Games in London. This seems very fitting given her focus on fitness and healthy eating through her Let’s Move! initiative. According to the AP:
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.
