John Oliver In Panic Mode After Ex Producer Threatens to Expose Alleged Toxic Workplace Environment

John Oliver is panicking after a former associate producer on Last Week Tonight dropped a bombshell on TikTok threatening to lift the lid on the hit HBO show’s allegedly toxic workplace environment.

“How it feels knowing I could tell anyone at any moment what an award-winning late-night show did to me after four loyal years of working there because I didn’t sign an NDA [nondisclosure agreement],” ex-Last Week Tonight staffer Katherine Nevitt-Chung, 30, taunted on April 30. She didn’t offer any specifics about her stint on the show.

The video has reportedly thrown John, the show’s 48-year-old U.K.-born host, and his staff into a tizzy.

“No one knows what this woman is going to spill, but it has the potential to topple things. If it does, it will be by far the biggest scandal,” says the insider.

The funnyman is “keeping tight-lipped about it,” but privately he’s spooked, says an insider.

“A lot of his enemies are relishing the potential downfall of John and Last Week Tonight and can’t wait to hear what this woman has to say. The worry is that other people will come forward — others who may not have signed NDAs,” says the insider.

“He’s trying to act as though it’s not happening but it’s clearly a huge problem for the show.”

The liberal comedian is famed for his jokes about President Donald Trump and for mocking MAGA supporters, which means plenty of people are “relishing” the his misfortune.

“People think John’s had a lucky run so far, given all the backs he’s put up with his jokes and put-downs and the open war he’s waged on conservatives,” the source says.
