Chelsea Clinton makes her first visit to the kitchen table with news about an issue that's very close to Rachael's heart - the fight to end childhood obesity. As Vice Chair of the Clinton Foundation, she's involved in their Alliance for a Healthier Generation's efforts, including reducing calories in school vending machines to encourage healthier eating habits among kids. "All of those changes, which individually might seem small, come together to make a really big impact," she explains. "What we're starting to see in some of our schools is that at least obesity levels have leveled off. They're not decreasing yet, but at least they're no longer increasing!"
