Who wrote the posse comitatus act?

Answer 1

On 27 May 1878, Representative J. Proctor Knott of Kentucky introduced an amendment to the Army appropriations bill; the amendment eventually became the Posse Comitatus Act. In passing the act, the Congress voted to restrict the ability of U.S. marshals and local sheriffs to conscript military personnel into their posses. They did not vote to preclude the use of troops if authorized by the president or Congress.
