District Judge Roger Vinson today issued an order granting the plaintiffs' motion to amend their complaint to add six states--Ohio, Kansas, Wyoming, Wisconsin, Maine, and Iowa--as plaintiffs in Florida v. HHS. You can access the order here.
Again, this runs the total of plaintiff states in the Florida case to 26, and the total number of states currently challenging the ACA to 27. If and when Oklahoma files its lawsuit, there will only be 22 states left not challenging the ACA in federal court.
