Steelers running back Rashard Mendenhall has received tons of criticism for his comments on twitter about September 11th and the death of of Osama bin Laden and rightfully so.

Mendenhall stirred up controversy with a conspiracy theory post about the attacks on the World Trade Center saying, “We’ll never know what really happened. I just have a hard time believing a plane could take a skyscraper down demolition style.”

He also posted a tweet about Osama bin Laden that questioned Americans’ celebrations over his death. “What kind of person celebrates death? It’s amazing how people can HATE a man they have never even heard speak. We’ve only heard one side…”

The Pittsburgh Tribune-Review says that Mendenhall could not be reached to comment on his controversial tweets.
