(USA Today) Fox News host Tucker Carlson used a portion of his show on Wednesday to address a now-viral video showing him cursing at a guest and calling him a moron during a segment that never aired.

While admitting the profanity-laced comments were “rude,” Carlson said they were “accurate” and added: “It was genuinely heartfelt. I meant it with total sincerity.”

The video was published by NowThis News Wednesday afternoon and within eight hours had been viewed more than 3.5 million times on Twitter. It appears to have been secretly recorded by Dutch historian Rutger Bregman or someone who was present for his interview with Carlson earlier this month.
