A former Cincinnati-area bartender charged with threatening to kill House Speaker John Boehner (BAY'-nur) is going to trial.

Michael Hoyt is charged with threatening to kill Boehner, either with a gun or by poisoning his drink. His nonjury trial is scheduled for Monday in U.S. District Court in Cincinnati.

Court documents indicate Hoyt has a history of mental illness. A judge found Hoyt competent to stand trial. But Hoyt's attorneys have said they plan to argue he was insane at the time of the alleged offense.

Hoyt was indicted in January. A separate criminal complaint said he was fired last fall from a suburban Cincinnati country club where Boehner is a member. Authorities say Hoyt said he began hearing the devil's voice after his firing, telling him Boehner was "evil."
