PIERRE, S.D. (AP) — South Dakota’s House is investigating whether the state’s attorney general should be impeached for his conduct surrounding a car crash last year that killed a pedestrian. A sizable majority of the Republican-dominated House voted Tuesday to have a committee recommend whether Attorney General Jason Ravnsborg should be impeached. It could take weeks for the committee of seven Republicans and two Democrats to delve into the crash investigation. Ravnsborg pleaded no contest in August to a pair of misdemeanors in the crash that killed 55-year-old Joseph Boever, who was walking along a rural stretch of highway when Ravnsborg struck him with his car.
