The updates about the U.S. Supreme Court's arguments today in King v. Burwell are coming fast and furious. The petitioners are seeking to invalidate the insurance subsidies in states with federal exchanges. SCOTUSBlog reports that Justice Anthony Kennedy, often the swing justice on the court, "expressed deep concern with a system where the statute would potentially destroy the insurance system in states that chose not to establish their own exchanges – likening this to an unconstitutional form of federal coercion. That made him seem skeptical of the petitioners’ reading of the statute, a hopeful point for defenders of the existing subsidies in all states."
