Renea Turner, who ran against Mr DeWine as a write-in candidate in 2018, posted a video to her Facebook on Thursday in which she places her hand on a Bible and proclaims herself the governor of Ohio.
“Ohio is free from Tyrannous leadership,” she wrote in a Facebook post following the stunt.
The Ohio Capital Journal was the first to report on the plot.
According to the individual – who asked local media not to identify them over fears of retribution – Ms Turner told them that they would kidnap Mr DeWine, try him for several alleged crimes, and then sentence him to exile or execution.
According to the whistleblower, the plot against Mr DeWine was a response to the governor’s coronavirus mandates.
