LONDON (AFP) - A protester hit Rupert Murdoch with a foam pie as the media mogul testified to British lawmakers on the phone-hacking scandal. The 80-year-old News Corporation chiefs Chinese-born wife Wendi Deng leaped up and slapped the assailant, who was dragged off by police after the attack during a parliamentary committee hearing quizzing Murdoch and his son James. The Guardian newspaper and Sky News named the attacker as a comedian called Jonnie Marbles. In a Twitter message shortly before the incident, he said: It is a far better thing that I do now than I have ever done before #splat. There was no confirmation of his identity as Scotland Yard had no immediate comment.
