NEW YORK - American football star Rashard Mendenhall has been dropped as an endorser by Champion, a leading clothing company, over his views on the twitter about Osama bin Laden and the September 11th attacks against the US As spontaneous celebrations broke out in the hours after the Americans learned that bin Laden was shot dead by US forces in Pakistan, Mendenhall, the Pittsburgh Steelers running back, used the social media site to denounce the response. What kind of person celebrates death? Its amazing how people can HATE a man they have never even heard speak. Weve only heard one side, Mendenhall wrote in a message posted to the social media site on Monday. Some Twitter users responded by asking if Mendenhall would have said the same thing when people celebrated Hitlers death, others said it was ignorant to give bin Laden the benefit of the doubt. Mendenhall posted a series of about six Tweets, including one questioning whether the collapse of New Yorks Twin Towers was actually the result of al Qaeda hijackers flying planes into the buildings. Well never know what really happened. I just have a hard time believing a plane could take a skyscraper down demolition-style, said Mendenhall of the incident on September 11, 2001 that claimed 2,752 lives in New York City. Champion, which produces sportsware, is ending our business relationship with Mendenhall since the athletic brand doesnt think he can appropriately represent Champion, spokesman Matt Hall was quoted as saying by the US media on Friday. While we respect Mr. Mendenhalls right to express sincere thoughts regarding potentially controversial topics, we no longer belief that Mr. Mendenhall can appropriately represent Champion, the company said. a
