A group of South Dakota Republicans wants the state party chairman to resign because of his lobbying work for Saudi Arabia. The Fall River County Republicans’ Central Committee unanimously approved a resolution on Tuesday night alleging that state GOP Chairman Dan Lederman has a conflict of interest. Lederman tells the Argus Leader he’s proud of his record as state Republican chairman. Lederman signed a contract last month to receive $10,000 per month to lobby for Saudi Arabia. The resolution has been sent to the party’s State Central Committee for consideration. Fall River County is in western South Dakota.
