The Congressman and some members of his family suffered scrapes and bruises, but they are otherwise fine, his office said.
Boswell was in his farmhouse outside Lamoni with his wife, Dody, his daughter, Cindy Brown, and his grandson, Mitchell Brown, when the intruder entered through the front door at approximately 10:45 p.m.
The intruder assaulted Cindy Brown and demanded money at gunpoint. The Congressman attempted to disarm the intruder while his grandson fetched the shotgun from another room, according to the statement. Mitchell Brown pointed the shotgun at the intruder, who then disappeared into the fields around the house.
Boswell spokesman Grant Woodard told the Associated Press that the family is shaken up but that “they’re dealing with it pretty well.”
The Decatur County Sheriff’s Department is investigating the incident with state and federal authorities.
