The man, identified as Randall Margraves, asked the judge if a "distraught father" would have a chance to say something after his daughters, Madison and Lauren, spoke.
He started off by saying "you son of a bitch" and then the judge told him not to use profanity. He also asked the judge to give him five minutes locked in a room with Nassar.
When the judge said no, the man asked for one minute, to which the judge again said no.
"Well I'm going to have to do something," the father said before charging toward Nassar.
He first stopped by Nassar's attorney, Matthew Newburg, before being restrained immediately by bailiffs in the courtroom while yelling "I want that son of a bitch," and saying "give me one minute with that bastard."
The attorney for the victims spoke to the gallery after the man rushed toward Nassar telling them to use their words and not use violence.
Judge Janice Cunningham, during a special hearing at a break in the sentencing, said she would not punish Randall for his actions.
"This was truly an immediate and emotional reaction of a father to hearing what you heard today," Cunningham said.
She added that she found out Margraves heard things on the record Friday that he hadn't known before, which she said could create the anger and rage he had.
