A man who claims that he was ordered to alter and hide documents relating to a probe of Gov. Nathan Deal before being fired by the chief of Georgia’s ethics agency has filed a whistleblower suit against the Government Transparency and Campaign Finance Commission and its executive secretary, Holly LaBerge.

The suit, filed in Fulton County Superior Court last week by the commission’s former media specialist, John Hair, is the third whistleblower action stemming from a dramatic shake-up at the agency in 2011, when its former director and her assistant were forced out in the midst of an investigation into Deal’s purported misuse of campaign funds.
