Remember the video of MSNBC host Lawrence O'Donnell acting like a complete asshole?

Well NBC fired the person responsible. 

Oh no....not O'Donnell, the staffer that leaked the video. 

Page Six says that sources said that a male “Today” show editor was found to be the culprit who compiled and leaked the eight-minute video of O’Donnell raging at staff during breaks in an Aug. 29 live broadcast of his show “The Last Word.”

A source told Page Six that “The video of Lawrence O’Donnell was leaked on Sept. 20. The leaker was identified, confronted and fired on Sept. 26. It turned out to be a ‘Today’ show editor who said he did it because he thought it was funny. But it wasn’t exactly the perfect crime — he left a very clear trail.”

We’re now told that the leaker, whose name has not been released, had left a clear digital trail that allowed NBC honchos to track him down. NBC declined to comment.

Despite the diva act,  O’Donnell remains employed.
