CHARLOTTE, N.C. — A federal prosecutor said Wednesday that a billionaire Durham businessman should spend 14 years in prison for trying to bribe North Carolina's top insurance regulator with large political contributions. 

U.S. Attorney Andrew Murray laid out the prosecution's sentencing recommendation against Greg Lindberg in a filing in federal court. Murray said that instead of showing contrition or remorse, the Durham businessman is unrepentant and blames others for his decision to offer a bribe to Insurance Commissioner Mike Causey.
