(Reuters) - Montana Republican congressional candidate Greg Gianforte was cited for a misdemeanor on Wednesday after a reporter accused him of physical assault on the eve of a special election to fill the state’s lone seat in the U.S. House of Representatives. The Gallatin County Sheriff’s Office issued Gianforte a citation for misdemeanor assault, hours after Ben Jacobs, a reporter for the U.S. edition of the Guardian newspaper, said in a Twitter post and in a television interview that Gianforte “body slammed” him at a campaign event in Bozeman.
