Jonathan Jennings was the first Governor to have an attempted impeachment brought against him in response to his actions as an agent of the federal government during the negotiations of the Treaty of St. Mary's in 1819, illegal under Indiana's constitution. The evidence of his role was destroyed, and after two months of investigation the proceedings were dropped. The only other time was when the General Assembly attempted to bring impeachment proceedings against Governor James B. Ray for a similar action in 1826, but the action was also defeated 28–30.
