Milwaukee County Sheriff David Clarke, one of the highest-profile members of law enforcement to emerge as a vocal supporter of President Trump, resigned from his position on Thursday.
County Clerk George Christenson said that he received a resignation letter from Clarke but that no reason for the move was provided.
Clarke issued a "retirement statement" to local media hours after his resignation was announced. "After almost forty years serving the great people of Milwaukee County, I have chosen to retire to pursue other opportunities," Clarke wrote. "I will have news about my next steps in the very near future."
