Tucker Carlson's departure from Fox News comes a month after his ex-producer Abby Grossberg sued him alleging a 'sexist' work environment

• Tucker Carlson's ouster at Fox News comes a month after Abby Grossberg, an ex-producer, filed a lawsuit against him.
• Abby Grossberg accused him and Fox News executives of running a workplace that "subjugates women."
• Fox News has denied her allegations and previously told Insider her legal claims "have no merit."

Tucker Carlson's ouster from Fox News comes a month after a former producer filed suit against him and other Fox executives, accusing them of running "a work environment that subjugates women based on vile sexist stereotypes."

Abby Grossberg — who booked top talent for "Tucker Carlson Tonight" before she was fired earlier this year — filed a complaint in a New York federal court on March 20.

"Ms. Grossberg was isolated, overworked, undervalued, denied opportunities for promotion, and generally treated significantly worse than her male counterparts, even when those men were less qualified than her," the complaint said.

Fox News has denied those allegations. A Fox News representative told Insider last week that the company would "vigorously defend Fox against all of her legal claims which have no merit."

"FOX News Media engaged an independent outside counsel to immediately investigate the concerns raised by Ms. Grossberg, which were made following a critical performance review," the representative said in the statement.

A Fox News representative and Grossberg's lawyers didn't immediately respond to requests for comment on Monday.

At more than 3 million viewers a night, Carlson was Fox News' top-rated host and the most popular of any news host on cable television.

In a short statement Monday, Fox News didn't say why Carlson was leaving the network. It only thanked the host "for his service" and said a rotating cast of interim hosts would take over. Sources told the Los Angeles Times that Carlson's exit is likely related to the Grossberg case.

It's unclear how or whether Carlson's exit from Fox News will affect Grossberg's lawsuit. The complaint names other Fox executives as well, and lawyers for Grossberg told Insider last week that they remained "as committed as ever" to pursuing litigation.

Carlson's departure comes just days after Fox News settled a lawsuit brought by Dominion Voting Systems for $787.5 million. Grossberg has also alleged that Fox News lawyers coached her to make false testimony during her deposition in the Dominion case.
