Tucker has made himself popular for things like going after public personalities most of the rest of the media won't touch.
He has further recently talked to the media, insisting that the NSA has been spying on him.
The man in the now-viral video has been recognized as Don Bailey, a local fishing guide. The video befell in Livingston Montana.
While it's not clear what Bailey's problem was, he was very hostile, and at the opening of the video, Tucker has to back him off.
Bailey goes on verbally striking Tucker. Tucker mentioned that his child is present, and that the man should control his language.
"I don't care, man. I want you to know: you are one of the worst human beings known to mankind. I want you to know."
"I'm not gonna do anything," interjects Tucker.
"What you have done to this state, to the United States, to everything else in this world," maintains the man, overlooking Tucker.
At this point, Tucker turns his head and sees the whole thing is being recorded. He begins to giggle.
"I don't care that your daughter is here, what you have done to people's families" Bailey presses on.
"I'm not gonna debate you," Tucker goes on.
"What you have done to everybody else in this world," repeats Bailey.
"Settle down, son," replies Tucker calmly.
"Son? Don't call me son ... number one..." says Bailey in vain as Tucker continues to walk away."
A Fox News spokesperson said "ambushing" Carlson while he was at the shop in Livingston with his family was "totally inexcusable."
"No public figure should be accosted regardless of their political persuasion or beliefs simply due to the intolerance of another point of view," the spokesperson said.
In a statement, the shop, Dan Bailey's Outdoor Company, announced the business was not related to the Dan Bailey shown in the video and continued: "To be clear, we treat every customer equally and respectfully. Our staff was professional and cordial to Mr. Carlson, as we are with all of our customers."
Throughout the pandemic, Carlson has cast doubt on Covid-19 vaccines, stating falsely that maybe the shots don't work and that thousands of people have died after having been inoculated.
The Anti-Defamation League, which tracks hate groups, has also called Carlson out for promoting or defending ideas embraced by white supremacists and conspiracy theorists.
In a letter in April, the group's leader asked Fox News Channel's top executive to dismiss Carlson.
Last week, as some Fox hosts pleaded with spectators to get vaccinated, Carlson went on to urge viewers not to "comply mindlessly" with public health guidance.
