Head of Medicaid to exit

The head of the country's biggest public insurance program and a champion of healthcare access for the poor will step down next month after five years. Cindy Mann, the deputy administrator at the Centers for Medicaid and Medicare Services (CMS), has earned praise nationwide as a fierce advocate for healthcare access and a key leader in the rollout of Obamacare. Under her leadership, the government made its "biggest improvements to the Medicaid program since its inception," the agency wrote in a statement Friday announcing her departure.
