CENTRAL CITY, Neb. (AP) — The Merrick County sheriff has resigned, saying he’d grown tired of his constant battle with a group of people who he says have been spreading lies.

Sheriff Kevin Campbell resigned at a meeting Tuesday of the Board of Supervisors. Board Chairman Roger Wiegert says the resignation took immediate effect and that Chief Deputy John Westman will be running the department until a replacement is hired.

Campbell says the lies being spread over social media have affected his family and says that he hopes his resignation will stop the attacks.

He’s been sheriff since 2010.
