Tucker Carlson s former producer at Fox News is out at the conservative network after a caption aired calling President Joe Biden a wannabe dictator.

The employee, identified by the Daily Beast as former Tucker Carlson Tonight managing editor Alexander McCaskill, resigned, Carlson said on his Twitter show Thursday.

The Daily Beast confirmed the parting with two sources, while Carlson offered his version.

First they scolded the producer who put the banner on the screen, Carlson said. Less than 24 hours after that, he resigned. He had been at Fox for more than a decade. He was considered one of the most capable people in the building. He offered to stay for the customary two weeks, but Fox told him to clear out his desk and leave immediately.

On Tuesday, Fox News Tonight showed a banner under side-by-side images of Biden and Donald Trump that read, Wannabe Dictator Speaks at the White House After Having His Political Rival Arrested.
