The father of three daughters who say they were sexually abused by disgraced doctor Larry Nassar lunged at him in a Michigan courtroom Friday, before being tackled to the ground by sheriff's deputies.
A dramatic video of the incident shows Randall Margraves at first standing calmly and calling Nassar a "son of a bitch." The judge says she understands his anger but asks him not to use profanity.
