AceShowbiz - Isaiah Washington made bombshell revelations regarding toxic work environment on "Grey's Anatomy" set. In a new interview, the 58-year-old actor, who played Dr. Preston Burke in the first three seasons of the series, said that Ellen Pompeo was paid to keep quiet about Patrick Dempsey's behavior.

During his appearance on KBLA Talk 1580 radio on October 21, the actor alleged that the Meredith Grey depicter "took $5 million dollars under the table." Claiming that it occured amid the Me Too era, Isaiah added that the money was to keep Ellen from "telling the world how toxic and nasty Patrick Dempsey really was."

In the interview, Isaiah also recalled the bad experience he had while on the show. "Every single day I was a problem that was being reminded, 'You're No. 4 on the call sheet. You're not the star of this show,' " Isaiah told radio host Tavis Smiley. He also said that he was "used as a scapegoat" to cover up other problems on set.

Calling that his 2007 firing as part of the hit show's "agenda," Isaiah added, "It was easy. I didn't know that it would stick to me so hard. But I found out why. It was an agenda to cover up for the toxic and bad behavior of many of my former castmates on that show. And the top of that would be Patrick Dempsey."

Isaiah went on to suggest that Patrick wasn't happy after he knew about how much Isaiah was paid on the show. "At this point, I was the highest paid person on that show, next to Patrick Dempsey. Apparently, it got out, so there was a lot of resentment. I understand that but it was based on my roles and my resume. I can't help that," he said. "He was called Pilot Poison. No one wanted him on the show. They wanted Rob Lowe."

Isaiah's allegations arrived after Lynette Rice claimed in a book titled "How to Save a Life: The Inside Story of Grey's Anatomy" that Patrick had "HR issues" that were "not sexual in any way" and involved him "terrorizing the set" at the time of his exit. "There were HR issues. It wasn't sexual in any way. He sort of was terrorizing the set. Some cast members had all sorts of PTSD with him," read an excerpt from the book.
