ABC News' Jessica Yellin hears that "when the First Lady speaks at the Clinton Global Initiative today she'll announce a new partnership with the Case Foundation (Steve and Jean Case) to help bring clean water to sub-Saharan African countries. They're investing in a system that uses merry-go-rounds. When kids play on the merry-go-round it powers septic systems to clean the water."
More Yellin: "Also expect the First Lady to highlight the Bush Administration's work on AIDS. Mrs. Bush will also address literacy, poverty, and global health."
