The controversial TV personality was abruptly taken off air last month shortly after Fox News settled a defamation lawsuit for $787.5m in which Mr. Carlson was implicated.
Former Fox News host Tucker Carlson intends to relaunch his show on Twitter, risking a battle with the news outlet that he remains contracted to, despite his dismissal last month.
Carlson stated in a video posted to Twitter with the caption “We’re back”: “Starting soon, we’ll be doing a new version of the show we’ve been doing for the last six and a half years on Twitter.”
Last month, Mr. Carlson was unexpectedly pulled from the air after the network stated that they “agreed to part ways.”
His departure followed Fox News’ parent corporation’s $787.5m (£631m) defamation settlement with voting system vendor Dominion.
Mr. Carlson was anticipated to testify and was implicated in the case. In messages that were used as evidence by Dominion, he made sexist and bigoted remarks.
The messages also revealed his private negative views about former US President Donald Trump and other Fox colleagues and executives.
However, his new Twitter show appears to violate the non-compete clause in his contract with Fox, which runs until 2025.
The clause prohibits him from joining a competing network or establishing his own.
Axios reported that Mr. Carlson’s attorneys sent Fox a letter alleging fraud and contract violation.
The announcement comes two weeks after Twitter owner Elon Musk sat down for a two-part interview with Tucker Carlson. However, on Tuesday, Musk tweeted that the company had not signed a contract with the television host.
On his controversial prime-time program Tucker Carlson Tonight, the host often embraced conspiracy theories and far-right issues.
Fox News, the most-watched cable news network in the US, got the greatest ratings among the crucial 25-to-54-year-old demographic.
But ratings in Mr. Carlson’s former slot slumped after he was ousted.
Nielsen reported that last week’s substitute anchor, Lawrence Jones, reached between 1.28 million and 1.7 million viewers at a time when Mr. Carlson typically drew three million viewers.
Fox has gained more than 40 new advertisers in that hour, the network said. Companies, such as Gillette, which considered Mr. Carlson’s program to be a toxic environment, have joined.
After becoming close to Trump, Fox removed Mr. Carlson without explanation.
The head of Fox News Lachlan Murdoch said this week that the company settled the lawsuit to avoid a divisive trial and protracted appeals process.
