In the video, posted by the account Libs of TikTok, a man can be seen arguing with an Allegiant Airlines flight attendant who mentions the “comment you’ve written on there” in regards to his mask.

The caption on the video says that the man’s mask had the phrase “Let’s Go Brandon”, a popular social media trend mocking the Biden administration and the media’s coverage of the president, written on it.

In a statement to Fox Business, Allegiant Airlines confirmed that the passenger was removed for disregarding instructions from a flight attendant.
