Cable news star Tucker Carlson is facing calls for his immediate firing from Fox News channel — but he’s not backing down.

As of right now, Fox Corp. is standing behind Carlson.

But will it last?

The Anti-Defamation League last week called for the company to fire the popular opinion host over his concerns on illegal immigration and voting rights.

The ADL called his on-air statements a defense of the white-supremacist “great replacement” theory.

In a letter sent Sunday to the civil rights group and shared with The Associated Press, Fox CEO Lachlan Murdoch said Carlson had “decried and rejected replacement theory” when he said during the Thursday evening segment, “White replacement theory? No, no, this is a voting rights question.”

The ADL argued in a reply sent Monday to Murdoch that Carlson used white-supremacist language even if he denounced the theory.

“Mr. Carlson’s attempt to at first dismiss this theory, while in the very next breath endorsing it under cover of ‘a voting rights question,’ does not give him free license to invoke a white supremacist trope,” wrote ADL CEO Jonathan Greenblatt.

During a guest appearance Thursday on “Fox News Primetime,” Carlson “embraced a foundational theory of white supremacy,” the ADL said, despite denying it beforehand.

During the show, Carlson said “the left and all the little gatekeepers on Twitter become literally hysterical if you use the term ‘replacement,’ if you suggest that the Democratic Party is trying to replace the current electorate of voters now casting ballots with new people, more obedient voters from the Third World.” He added that he had “less political power because they are importing a brand new electorate.”

Carlson himself fired back on Monday night, re-airing the controversial clip with the entire conversation. He refused to back down —

Murdoch noted in his letter that the ADL had once honored his father, Rupert Murdoch, with a leadership award. The ADL’s Greenblatt replied that the award was granted “over a decade ago, but let me be clear that we would not do so today, and it does not absolve you, him, the network, or its board from the moral failure of not taking action against Mr. Carlson.”

A Fox spokesperson declined to comment on the ADL’s Monday letter.

What are your thoughts?

Should Tucker Carlson be fired for his comments — or did the “woke mob” take his statements out-of-context (again?)
