On the same day that officials at Little Dixie Community Action Agency in Hugo, Okla., won a $580,000 federal grant to help consumers sign up for coverage under the federal health law, they received a warning from the state's top insurance regulator. Commissioner John Doak said that if the new insurance guides known as "navigators" perform any of the duties of state-licensed insurance agents, "we will put a stop to it." He also called the $1.6 million award to hire and train navigators in Oklahoma — part of $67 million nationwide — "a waste" because it would duplicate the work of better-trained agents.
