A Mississippi man was sentenced to 10 months in prison and anger management counseling for threatening to kill President Obama and to blow up the hospital that refused to treat his wife. David Williams, 45, of Attala, pleaded guilty in August to a two-count federal indictment. Prosecutors said Williams called the University of Mississippi Medical Center in Jackson in July to schedule surgery for his wife. When the hospital refused his request, Williams became angry and threatened to blow up the hospital. Secret Service documents filed in the case said he also threatened to kill Obama, whom he referred to using a racial slur.
