Former O.J. Simpson attorney Robert Shapiro has been defending and rationalizing the Paris Hilton side of the story during talk-show visits on MSNBC and CNN. Radar‘s Jeff Bercovici is reporting that he’s not only a paid shill, but that he hasn’t informed MSNBC producers of this fact. (A CNN spokesperson told Bercovici he/she “could not immediately say whether its producers had knowledge of the arrangement.”) Last Friday Shapiro was a guest on both MSNBC’s “Countdown” with Keith Olbermann and CNN’s “Anderson Cooper 360″ to discuss the case.
