"Although the text of the petition states that former U.S. president George Bush is a (board) member of the Barrick Gold Corporation, this does not appear to be the case. George H. W. Bush (who served as President of the United States of America from 1989-1993 and is the father of the current U.S. president, George W. Bush) was Honorary Chairman of Barrick's International Advisory Board from 1995 to 1999. He is not now listed as a member of the corporation's Board of Directors." (from Snopes)

FYI, Barrick Gold is a Canadian company, and we should be ashamed.
