Kroger Chairman and CEO resigns following investigation into personal conduct

Kroger Chairman and CEO Rodney McMullen has resigned after an internal investigation into his personal conduct.

Kroger, the nation’s largest grocery chain, said Monday that the investigation into McMullen’s personal conduct was unrelated to the business, but was found to be inconsistent with its business ethics policy.
