The National Association of Insurance Commissioners named ex-Democratic Senator Ben Nelson to be its chief executive officer as the regulators' group tackles U.S. President Barack Obama's health-care overhaul. Nelson's duties will include working with U.S. and international agencies as overseers increase their scrutiny on financial firms, the NAIC said today in a statement. A former industry executive, Nebraska governor and state regulator, he was one of the more conservative Democrats in the Senate.
