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.
Republican Rep. Darrell Issa, who chairs the House Oversight Committee, is hinting at a broader investigation of President Obama's Secret Service detail after revelations that 11 agents were sent home from Colombia for alleged misconduct involving prostitutes.
Issa of California told CBS This Morning that lawmakers will "look over the shoulder" of the Secret Service as it conducts its own internal investigation of the alleged incident that occurred ahead of the Summit of the Americas in Colombia, which President Obama attended.
