Gianforte, a wealthy former software executive, has called for civility in politics following his conviction for assaulting a reporter the day before winning a special congressional election.
Gianforte won a May 25 special election to serve the remaining 18 months in the House term vacated by now-Interior Secretary Ryan Zinke. Gianforte has already filed for re- election. He will be sworn in today by House Speaker Paul Ryan.
