OKLAHOMA CITY • A county commissioner in far southeast Oklahoma who was identified by a local newspaper as one of several officials caught on tape discussing killing reporters and lynching Black people has resigned from office, Gov. Kevin Stitt’s office confirmed Wednesday.

Stitt spokesperson Carly Atchison said the office received a handwritten resignation letter from McCurtain County Commissioner Mark Jennings. In it, Jennings says he is resigning immediately and that he plans to release a formal statement “in the near future regarding the recent events in our county.”

The threatening comments by Jennings and officials with the McCurtain County Sheriff’s Office were obtained following a March 6 meeting and reported by the McCurtain Gazette-News earlier this week in its weekend edition. They have sparked outrage and protests in the city of Idabel, the county seat.

In a post on the sheriff’s office Facebook page on Tuesday, officials did not address the recorded discussion but claimed the recording was illegally obtained.

Also on Wednesday, the Oklahoma State Bureau of Investigation confirmed it has launched an investigation into the matter at the request of the governor.

The recorded conversation included Sheriff Kevin Clardy, sheriff’s Capt. Alicia Manning, Jennings and Jail Administrator Larry Hendrix. During that conversation, Clardy, Manning and Jennings appear to discuss Bruce Willingham — the longtime publisher of the Gazette-News — and his son Chris Willingham, a reporter.

Jennings tells Clardy and Manning “I know where two deep holes are dug if you ever need them,” and the sheriff responds, “I’ve got an excavator.”

Jennings also says he’s known “two or three hit men” in Louisiana, adding “they’re very quiet guys.”

In the recording, Jennings also appears to complain about not being able to hang Black people, saying: “They got more rights than we got.”

The Associated Press is working to verify the authenticity of the recording. None of the four officials returned telephone calls or emails from The Associated Press seeking comment.

Bruce Willingham told the AP the recording was made when he left a voice-activated recorder inside the room after a county commissioner’s meeting because he suspected the group was continuing to conduct county business after the meeting had ended, in violation of the state’s Open Meeting Act.
