Fallout from "Grey's Anatomy"

T.R. Knight rose to fame when he joined the cast of the ABC medical drama "Grey's Anatomy." He played the role of George O'Malley until the fallout in 2009. His disappearance from the show was far from smooth as the "Isaiahgate" controversy forced him to leave. In 2009, he opened up about the issue to Entertainment Weekly, stating the reason behind his departure. During his interview, he said: "My five-year experience proved to me that I could not trust any answer that was given [about George]. And with respect, I’m going to leave it at that."

The fallout began when the media frenzied on Isaiah Washington calling T.R. Knight f****t in one of the show's on-set production. Washington was eventually fired from the show, T.R. Knight, on the other hand, decided to leave following the incident.
