Ann Coulter, if you haven't heard of her, is an American conservative columnist and speaker.
She's recently thrown her weight behind Donald Trump, having written a book called In Trump We Trust and recently campaigned for him, saying a Hillary Clinton presidency would bring about the end of the United States.
