First lady Michelle Obama is launching a nationwide campaign against childhood obesity. It's part of her effort to teach America's children about better nutrition and exercise.
She says the Let's Move campaign will encourage more physical activity for children -- along with healthier food in schools and more accurate food labeling. Some of her initiatives will require congressional action -- including tax breaks for grocery stores to move into poorly served communities.
In the Oval Office today, President Barack Obama signed a memorandum creating a task force on childhood obesity. He said his wife is tackling one of "the most urgent health issues facing the country."
