‘If Megyn is leaving they better also be telling us that Jackie Levin is following her out the door,’ said the insider, referring to the show’s executive producer.

‘This needs to be a joint departure as they have simultaneously created a toxic environment that needs to be wiped clean from NBC News forever.’

That individual went on to explain: ‘Executive producers are responsible for their talent, and while I use that word lightly when describing Megyn, Jackie had zero control of her and enabled a culture of toxicity at the show.’

The insider also expressed her belief that Noah Oppenheim and Lack should have fired Levin when an internal memo detailing how much employees did not like working for her was leaked to DailyMail.com.
