The state legislature brought impeachment trials against the governor, Kansas Secretary of State J. W. Robinson and State Auditor George S. Hillyer, over what they believed to be the unlawful sale of state bonds to help raise Union troops. They were convicted of selling state bonds in direct violation of the laws of the state, but found innocent of conspiracy and other articles of impeachment. Only three state senators voted to impeach the governor, who was less directly involved in the sale of the bonds.
