Hillary Clinton tells heckler 'you are very rude'

US Democratic presidential candidate Hillary Clinton told a heckler she was "very rude" during a town hall event in New Hampshire.

The woman, who later identified herself as Republican New Hampshire state representative Katherine Prudhomme O'Brien, repeatedly stood up and shouted, but Clinton refused to take her question.

"You are very rude and I'm not going to ever call on you," Clinton told her.
