COLUMBIA — A plan to hire lawyers to review state retirement investments for fraud has prompted bickering between South Carolina’s attorney general and treasurer.

Attorney General Alan Wilson said Wednesday that Treasurer Curtis Loftis had supported plans to use outside law firms to find fraudulent pension fund investments and now has done an about-face.

A law firm that Wilson chose donated to his campaign.

Loftis says he’s the custodian of the pension funds and the contracts need to be handled without political involvement or interference. He says campaign donations have no place in the decision process in protecting a $26 billion trust fund.

Wilson said the donations aren’t a factor in his decisions.

Loftis faced questions this year after his personal lawyer began handling a major lawsuit involving pension funds.
