A battle over gun insurance is forming with a New York regulator fining insurers and brokers of National Rifle Association-branded policies for selling policies within the state that cover legal costs connected with criminal defense expenses that might arise from legal gun ownership. The fined companies have stopped selling the policies, and the NRA has filed a federal lawsuit against the insurance broker for withdrawing.

On Friday, the National Rifle Association filed a lawsuit against Democratic Gov. Andrew Cuomo and the Department of Financial Services and Superintendent Maria Vullo in federal district court in Albany alleging that they are depriving NRA members’ constitutional rights in the state’s regulatory actions against insurers providing gun owner liability insurance in New York. The governor called the lawsuit “frivolous,” according to an Associated Press report.
