First lady Michelle Obama wears many hats in the White House. In addition to being President Obama's closest confidante, she's also a mother whose two daughters are growing up in one of the most public homes in America.
And as first lady, Mrs. Obama has taken on her own signature public issues, as well.
Her Let's Move campaign has brought attention to the growing epidemic of childhood obesity. She has encouraged children to eat right and get plenty of exercise.
And as she tells Tell Me More host Michel Martin, Mrs. Obama has also been working on a new initiative with Dr. Jill Biden, wife of Vice President Joseph Biden, to help U.S. veterans integrate into civilian life and cope with the lasting effects of wartime deployments.
