LONGWOOD, Fla. (AP) -- Michelle Obama is spending her Saturday morning at a Florida church, talking with religious leaders about their role in helping people eat better and become more physically fit.
It's part of the first lady's three-day national tour to mark the second anniversary of her "Let's Move" campaign against childhood obesity.
During a stop in Longwood, Florida, she told a crowd of more than 3,000 people from 15 denominations that they're taking on one of the most urgent challenges of our time. She said they're showing that no problem is "too big, too complicated, too entrenched to be solved."
Her office also announced a new video challenge. Churches and other organizations can send in videos showing what they're doing to help kids get healthier.
