Nutter said unexpected potty-mouth language early in the event, apparently from Wayans, may have made the TV station trigger-happy with the censor button, which cut out not just the audio but also the video, blacking out the screen momentarily.
He said Minaj's four expletives all occurred in the same song. Vicci Martinez's cursing was limited to one word said twice within a five-second span. Aloe Blacc and Jennifer Hudson did not use offensive language, he said.
Nutter didn't go into details on Wayans, a comedian who "clearly used inappropriate language on the stage."
As for dealing with the artists who violated "network broadcast standards," Nutter said the city would look at its options but was primarily concerned with making sure this doesn't happen in the future.
Asked if he was personally offended by Minaj's songs or performance, Nutter said: "I don't know the particular song, I don't know the lyrics in their context or what it's even communicating.
"I mean, look, I'm not a kid. I've heard all these words before in my time. My job and my responsibility is to make sure that we have a good, clean fun opportunity," Nutter said. "My personal views here are less important than making sure things like this don't happen in the future. I listen to a wide variety of artists."
