Gov. Nathan Deal, two top aides and his private attorney have been subpoenaed and may testify in an ethics-related whistleblower lawsuit, according to records obtained by the The Atlanta Journal-Constitution.

Deal, chief of staff Chris Riley, chief counsel Ryan Teague and the governor’s private campaign attorney, are on the “may call” list of witnesses for Sherilyn Streicker, the former top deputy of the state ethics commission, according to a pre-trial brief outlining evidence and potential witnesses.

Streicker has sued her former employer, claiming she was fired for aggressively pursuing an ethics complaint against Deal’s 2010 campaign.

The trial is set to begin Friday in Fulton County Superior Court and is set to last five days.
