"The "clarification" that Steelers halfback Rashard Mendenhall wrote in his blog Wednesday ignored a particularly incendiary Twitter post by him after the death of Osama bin Laden that set off a firestorm of protest around the country.

In a 500-word blog post , Mendenhall said he in no way supported bin Laden, expressed sympathy for those killed by the Sept. 11, 2001, terrorist acts and affirmed his support for the military. He apologized, not for what he wrote, but for anyone hurt by what he wrote and the timing of it. He said the thoughts were merely his opinions.

He explained only one of his series of Monday tweets that landed him among the most discussed topics on the popular social networking site.

Mendenhall cited his religious beliefs in his blog for questioning why people celebrated the death of bin Laden. However, he did not mention the other Twitter post that enraged many people: "We'll never know what really happened. I just have a hard time believing a plane could take a skyscraper down demolition style"

That tweet was removed from Mendenhall's Twitter comments Tuesday.

According to a Mendenhall representative, the words in his blog are his and not written by someone for him.

The series of comments Mendenhall posted Monday on Twitter brought a response from Steelers president Art Rooney II, who said in a statement that "it is hard to explain or even comprehend what he meant." Rooney offered no comment on Mendenhall's clarification."
