A senator has apologised for saying he was surprised that a gun magazine with a photo of Hillary Clinton on the cover had not put a bullseye over her face.
Richard Burr made the comment on Saturday during a private gathering of Republicans. Broadcaster CNN obtained audio from the event in which the North Carolina senator is heard saying he saw a copy of American Rifleman in a gun shop.
He said: "It's got a picture of Hillary Clinton on the front of it. I was a little bit shocked that it didn't have a bullseye on it."
His Democratic challenger, Deborah Ross, said on Twitter that his comments were "dangerous and irresponsible".
Mr Burr later said in a letter to The Raleigh News & Observer: "The comment I made was inappropriate and I apologise for it."
