The First Lady at 50
As the wife of the 44th President of the United States, Michelle Obama has made an indelible impression with her signature style and equally impressive career. But she says that, first and foremost, she is "Mom in Chief" to daughters Malia and Sasha.
A former lawyer and civil servant, she is an advocate for working parents, military families and national service. Dubbed "The First Lady the World's Been Waiting For" by Vogue, Michelle says her intention as First Lady is to open up the White House, help working women, like herself, balance career and family, and end childhood obesity with her Let's Move! Initiative.
As the toned-armed powerhouse celebrates a milestone birthday, we take a look back at some of her key moments.
