Responsibility for implementing the Affordable Care Act (ACA), in line with Congressional intent, rests with the US Department of Health and Human Services (HHS). The 21st secretary of HHS, Kathleen Sebelius, discusses the impact of the law since it was passed under her watch in 2010. She'll also talk about the provisions Congress might alter, the extent to which the executive branch can chip away at the ACA without new legislation, and whether there is any room for compromise. Looking into a crystal ball, she also offers insights about the future direction of the government’s role in health.
