CINCINNATI — A former Cincinnati-area bartender who said he heard the devil’s voice telling him that House Speaker John Boehner was evil is set to go on trial Monday in federal court on charges he threatened to kill the Republican lawmaker.

Michael Hoyt has pleaded not guilty to a charge of threatening to kill a government official. He is scheduled for a nonjury trial in US District Court in Cincinnati. Authorities have said in court documents that he threatened to kill Boehner with a gun or by poisoning his drink.

Court documents also indicate that Hoyt, of Deer Park, has a history of mental illness. But Judge Timothy Black in April ruled that Hoyt was competent to stand trial, based on a report from a medical facility where Hoyt was sent for evaluation and treatment.
