— Federal investigators from the U.S. Attorney's Office for the Western District of North Carolina announced indictments this past week that outlined allegations of fraud and bribery against the chairman of the North Carolina Republican Party, a wealthy Durham businessman and two of his associates, one of them a chairman of the Chatham County Republican Party.

While that investigation continues, so does a separate probe underway by investigators in the Eastern District of North Carolina into election improprieties in the 9th Congressional District. Five people have been indicted in that investigation, and more indictments are expected. That case involves election fraud, and one of the people indicted was running an absentee-ballot operation for Republican candidate Mark Harris.

In the new case, Durham businessman Greg Lindberg is accused of trying to bribe Republican Insurance Commissioner Mike Causey to gain favorable treatment for one of his hundreds of insurance companies. Causey, however, had reported the overtures to the FBI and, according to the indictment, began assisting the FBI in its investigation.

In the last three years, Lindberg has become the largest single political donor in North Carolina. Most of his contributions have gone to Republicans, but he also supported Causey's predecessor, Democrat Wayne Goodwin, who is now chairman of the North Carolina Democratic Party.
