Robert De Niro should be removed as the official voice of the audio guide for the 9/11 Memorial.  His repeated disrespect for the office of the Presidency should disqualify him for such an honor. His vulgarity towards the President on numerous occasions, including recently in front of children at their high school graduation and on television at the Tony Awards, has alienated a large number of Americans.  These Americans should not be forced to listen to De Niro's voice during such an emotional tour.  SIGN THE PETITION NOW to remove De Niro from the 9/11 audio guide!
