TYNDALL, S.D. (AP) — A South Dakota sheriff waited a whole minute after polls closed to fire a deputy who undid his re-election bid this week.

Bon Homme County Sheriff Lenny Gramkow fired deputy sheriff Mark Maggs after Maggs defeated him by a vote of 878-331 in Tuesday’s Republican primary election. Maggs posted his time-stamped termination notice signed by Gramkow on Facebook after polls closed.

Gramkow didn’t give a reason for the firing. South Dakota is a right-to-work state where employees can be fired without cause and the state’s sheriffs have the authority to hire and fire personnel.

Gramkow declined to comment about the firing. Maggs planned to meet with the county commission on Thursday.
