Tucker Carlson and Fox News is heating up. The cable news network, which announced on April 24 that it had “agreed to part ways” with its star anchor, sent Carlson a cease-and-desist letter on June 7 over his newly launched Twitter show, according to a person familiar with the matter. Fox News did not respond to a request for comment. The letter arrived hours after Carlson’s first show posted on the social media platform on June 6. The episode, clocked at 10 minutes and 27 seconds, was taped in Carlson’s home studio in Maine and took swipes at everyone from Senator Lindsey Graham to Ukraine president Volodymyr Zelenskyy to the mainstream media. It has notched 114.8 million views so far. A second episode, which posted on June 7 and runs slightly longer at 12 minutes and 38 seconds, boasts 54.9 million views to date, according to Twitter’s own measures.
