UPDATE: Rashard Mendenhall tried to clarify his tweets about Osama bin Laden on Wednesday.
"This controversial statement was something I said in response to the amount of joy I saw in the event of a murder," he said in a blog entry. "I don't believe that this is an issue of politics or American pride; but one of religion, morality, and human ethics."

"What kind of person celebrates death?" the Pittsburgh Steelers running back tweeted. "It's amazing how people can HATE a man they have never even heard speak. We've only heard one side..."
He also expressed his opinions on whether the planes that hit the World Trade Center on September 11 caused them to collapse.
"We'll never know what really happened. I just have a hard time believing a plane could take a skyscraper down demolition style," Mendenhall said.
“I have not spoken with Rashard so it is hard to explain or even comprehend what he meant with his recent Twitter comments,” Rooney said. “The entire Steelers’ organization is very proud of the job our military personnel have done and we can only hope this leads to our troops coming home soon.”
