Attorney and former Georgia Insurance Commissioner John Oxendine, fighting a state ethics investigation tied to his 2010 run for governor, has asked a judge to quash a subpoena seeking his law firm‘s financial records.

Oxendine’s Aug. 29 petition in Fulton County Superior Court said the records are protected by attorney-client confidentiality and that many of his firm’s clients are “regulated entities in the insurance and/or healthcare arena” who “often do not want the fact that they have hired a well-known regulatory and healthcare law firm as a matter of public record.”
