MSNBC's Lawrence O'Donnell is seen yelling obscenities at staff members during eight minutes of outtakes in recently surfaced footage from an August broadcast.

During the outtakes, O'Donnell screams at staff over loud noises coming through his earpiece from the control room, for hammering coming from another room, and the editing of a news package set to air on the show.

The longtime news anchor apologized on Twitter Wednesday night, saying a "better anchor" and "better person" would have had a different reaction.

O'Donnell has been host of "The Last Word with Lawrence O'Donnell," a weeknight MSNBC opinion news show since October of 2011.
