There are a lot of mysteries surrounding the firing of Fox New's Tucker Carlson. Still, according to a report, executives at the network prepared beforehand to deal with their primetime host if he badmouths his former employer after he was dismissed. Executives reportedly possess a dossier of alleged dirt on Carlson in case he attacks the network.

Rolling Stone reports:

But if Carlson attempts to torch the network he's leaving, Fox is prepared, the sources say.
Eight people familiar with the situation tell Rolling Stone that Fox News and its communications department — long led by the notoriously aggressive Irena Briganti — have assembled damaging information about Carlson. One source with knowledge calls it an "oppo file." Two sources add that Fox is prepared to disclose some of its contents if execs suspect Carlson is coming after the network.

The file includes internal complaints regarding workplace conduct, disparaging comments about management and colleagues, and allegations that the now-former primetime host created a toxic work environment, three of the sources say. (Carlson is currently facing a lawsuit from a former senior booking producer, Abby Grossberg, alleging a toxic and misogynist workplace environment. The lawsuit details repeated instances of misogynist behavior at the network, including frequent lewd and sexual discussions of female guests and public figures. Grossberg, "continued to endure a work environment that subjugates women based on vile sexist stereotypes, typecasts religious minorities and belittles their traditions, and demonstrates little to no regard for those suffering from mental illness." Fox denied the allegations when the lawsuits were filed, saying the claims were "without merit.”)

While the network denied the allegations, many sources disagree. "Irena will never be shy about using these things," one insider said.

A former Fox News anchor said, "Irena tries to keep a file on everybody … Any talent like Tucker would have a lot of things; other people complaining. They encourage it and then just keep it on file. It's just a classic dirty trick."

"[Briganti] keeps files on everybody to screw with them," an ex-Fox News host adds. "It's classic Fox."

From what we're gathering here, it looks like Tucker's departure has been on Fox News's executives' to-do list for a while, and they were prepared. What a fun place to work.
