In the wake of Minnesota's 7-billion dollar settlement with the tobacco industry, Blue Cross Blue Shield could face its own lawsuit. Some policyholders are considering filing a class-action suit, to force the insurance company to return its share of the settlement to people who paid premiums. Minnesota Public Radio's Laura McCallum reports... Under the terms of Friday's settlement, tobacco companies will pay Blue Cross Blue Shield of Minnesota nearly 470-million dollars over five years. The state's largest health insurer says it will use that money for smoking cessation programs and research into tobacco prevention.
