So, this clarifies a lot of things about their current relationship:

The intrigue: The Twitter move would seem to technically violate Carlson's contract with Fox, but his lawyers' letter effectively holds that Fox breached the contract first.

Sources told Axios that Carlson's lawyers sent their letter before he took to Twitter to announce his new show.

Essentially this means that Tucker is on the offensive, he is trying to freeze FOX before they begin destroying any evidence.

The details: The letter — from Carlson lawyer Bryan Freedman to Fox officials Viet Dinh and Irena Briganti — said Fox employees, including "Rupert Murdoch himself," broke promises to Carlson "intentionally and with reckless disregard for the truth."

The lawyers accuse Fox executives — which two sources say are Dinh and Murdoch — of making “material representations,” or promises, to Carlson that were intentionally broken, constituting fraud.

Notably, the letter alleges Fox broke an agreement with Carlson not to leak his private communications to the media and not to use Carlson's private messages "to take any adverse employment action against him."

Multiple outlets have reported on Carlson's redacted communications from pre-trial discovery documents and have suggested that they led to his ousting. The letter also alleges Fox broke promises not to settle with Dominion Voting Systems "in a way which would indicate wrongdoing" on the part of Carlson and not to take any actions in a settlement that would harm Carlson's reputation.

Carlson was told by a member of the Fox board that he was taken off the air as part of the Dominion settlement, two sources briefed on a conversation told Axios.

According to a source familiar with Carlson's position, his lawyers believe that the misrepresentations alleged by Carlson amount to a breach of contract because they created additional terms of Carlson's employment that were then broken by the company.

"These actions not only breached the covenant of good faith and fair dealing in the Agreement, but give rise to claims for breach of contract, and intentional and negligent misrepresentation," the letter says.

A Fox News spokesperson said it is "categorically false" that Carlson lost his job as part of the network's $787.5 million settlement with Dominion Voting Systems.

Stephen Shackelford, an outside attorney for Dominion, told Axios' Dan Primack: "Dominion did not insist on them firing Tucker Carlson as part of the settlement."

What's next: Carlson is also claiming that Briganti, Fox's longtime communications and PR chief, attempted to "undermine, embarrass, and interfere" with Carlson's future business prospects, which he maintains would constitute another breach of his employment contract.

"Make no mistake, we intend to subpoena Ms. Briganti’s cell phone records and related documents, which evidence communications with her and all media, including, but not limited to The New York Times," the letter said.

What to watch: Carlson's lawyers added that because Carlson is considering litigation against the network to resolve these disputes, Fox News must take immediate steps "to preserve all existing documents and data" relevant to Fox’s relationship with Carlson, including correspondence between top executives and several media outlets.

If he is going on the offensive so early he must have knowledge of communications which would essentially destroy FOX. FOX may end up paying him out the entire terms of his contract plus an additional settlement on top of destroying his non-compete.

How fucking stupid are these people?
