Fox News accused its former prime-time star Tucker Carlson of breaching his contract after he launched a new opinion show on Twitter this week, according to Axios and Mediaite .

Both media outlets said that lawyers for Fox News sent a letter to Carlson setting up a possible legal showdown.

Carlsons new show, a 10-minute tour of various conspiracy theories , launched Tuesday on the platform now controlled by right-wing billionaire Elon Musk.

The host promised to be back with much more, very soon. (His home in Maine has a full production studio.)

He was dumped from Fox in the wake of the devastating legal settlement reached in mid-April with Dominion Voting Systems, which had sued for $1.6 billion alleging the network knowingly spewed damaging lies about its machinery as it spread false claims that the 2020 presidential election was stolen from Donald Trump . Fox agreed to fork over $787 million to avoid a potentially humiliating trial. The network announced the following week that Carlson would be leaving, although it did not give an explanation.

According to Axios , Carlson accused Fox News of breaching its side of his contract in May, setting his lawyers up to argue that a noncompete provision in the contract was no longer valid. Carlson said he was told his ouster came as part of the settlement with Dominion, Axios and Variety reported . Fox News denied that was the case.

Fox News was still paying Carlson his $20 million salary while their legal battle plays out, according to Variety.

The network did not return HuffPosts request for comment.

Carlson had made a name for himself in his six-plus years at Fox News by ranting about conservative bogeymen, including immigrants and progressive Rep. Alexandria Ocasio-Cortez (D-N.Y.).
