Charna Flam A producer for Fox News who had previously worked on “Tucker Carlson Tonight,” Alex McCaskill, has exited the network after he was considered responsible for Tuesday’s on-air headline that referred to President Joe Biden as a “wannabe dictator.” In its entirety, the headline read: “Wannabe dictator speaks at the White House after having his political rival arrested.” The chyron was featured during a broadcast covering the indictment of former President Donald Trump. According to the Associated Press, Fox issued a statement the following morning saying that the chyron had been taken down and “addressed.” McCaskill then sent in his letter of resignation but was met with a request for an immediate departure, the AP reported.
