David Emadi, the executive secretary of the state ethics commission, confirmed the investigation. All three people have denied the accusations.
Austin-Gatson’s complaint said Porter acted “maliciously and with reckless disregard for the truth” when he spoke to TV stations about the investigation and posted a statement on his Facebook page that he also sent to news media.
“Danny Porter doesn’t have the right to accuse people of crimes in public,” Austin-Gatson said.
The DA’s race is on the ballot Nov. 3.
