The Affordable Care Act became law because five congressional leaders made it happen. These committee chairs — two from the US Senate, three from the House of Representatives — share the stage to talk about the passage, impact, and future of the ACA. As the law’s key architects, all five bring insider knowledge of the maneuvering, negotiation, and compromise that led to its passage in 2010. They also bring candor — four have already retired from Congress and the fifth will not run again when his term expires this year. The gathering marks the first time these players have come together at a public venue since the ACA was enacted.
