Rupert Murdoch, the Chairman and CEO of News Corporation, was the target of "a white foam pie" attack on Tuesday as he was testifying before a British Parliament committee about the News of the World phone hacking scandal.
According to Daniel R. Hamilton, the Director of Big Brother Watch, Marble's real name is Jonathan May-Bowles. In his Twitter profile, Marbles calls himself an "activist, comedian, father figure and all-round nonsense."
The Los Angeles Times reports that Murdoch's glasses came off in the attack. The hearing was suspended for ten minutes and Murdoch returned wearing shirtsleeves, "apparently unharmed," according to Channel 4 News.
