I think someone is bitter :)

"They fired the wrong guy," Isaiah Washington said today.

The former Dr. Preston Burke on ABC's hit series Grey's Anatomy told the Houston Chronicle that T.R. Knight should have been fired from the show.

"I have to clear my name," a determined Washington told the Houston Chronicle
Washington said Knight, who plays Dr. George O'Malley, stirred up the notion that the slur was targeted at him and created a negative work environment. Washington also alleged that Knight likely wanted a salary increase and a more substantive role for his character.
Knight, who acknowledged that he was gay after the incident, told Ellen DeGeneres in January that Washington used the slur against him and that "everyone (on the set) heard it."

"That's a lie," Washington said. "I used the word during a disagreement with Patrick. I apologized for that. We shook hands and went back to work." (source)
