Cornelius' latest complaint alleges Lisa Hopkins, general counsel for the auditor's office, represented Gainer and that other staff members helped conduct research on the case.
The complaint includes an email from Barb Wolfe, a legal assistant in the auditor's office, to Mary Claire Akers, general counsel for the ethics commission. News articles about the complaint and the Visa videos are attached to the email.
"Lisa Hopkins wanted me to forward these to you for your information," Wolfe writes in the email to Akers. Hopkins is also copied on the email.
According to the ethics complaint, Justin Southern, spokesman for the office, first sent the articles to Hopkins. Cornelius argues this is evidence Hopkins and Southern helped Gainer to some degree.
Cornelius also states he tried to "gather facts" by sending Freedom of Information Act requests to the auditor's office and the ethics commission. He asks for any communication about Gainer's appearance in the Visa videos, following ethics complaint or media coverage of the situation.
Both the commission and auditor's office declined to provide the information, saying the documents were exempt from state FOIA laws. They site several different exemptions.
In her response, Hopkins said the complaint is politically motivated. She also wrote that she believes Cornelius received copies of the documents outlining the ethics commission's decision. She said to let her know if he needed another copy.
"That would seem to certify her involvement in the negotiation (and) resolution of the case," Cornelius wrote in the newest complaint.
Reached late Monday, Southern said he did not know about the complaint until contacted by the Daily Mail. He later released a statement saying the office did nothing and the complaint was made for political purposes.
"While we haven't received the complaint, this appears to be another thinly veiled attempt by Republican operatives to manipulate and misuse the ethics commission for their own political gains," Southern said.
"We believe everything was done appropriately under the circumstances."
Ethics Commission proceedings are confidential until a decision or settlement is reached.
The commission issued no public reprimand against Gainer in connection with the first complaint. It cited press coverage of the situation, the fact it was the first complaint against Gainer during his 20 years in office and Gainer's cooperation.
