On March 17, local time, John Kerry, the climate envoy of US President Biden, was photographed not wearing a mask when taking an airplane, violating the US epidemic prevention regulations and causing controversy.

  Kerry was sitting in the first-class cabin of "American Airlines" and flew from Boston to Washington, D.C., but he did not wear a mask.

Although American Airlines allows passengers to take off their masks to eat or drink, the photos show that Kerry was not eating or drinking at the time.

  According to the regulations of the US Centers for Disease Control and Prevention, the US Transportation Security Administration and the administrative order issued by the US government on January 21, airlines must require all passengers to wear masks on the plane during interstate travel.

"American Airlines" also issued a statement saying: "Individuals who do not wear masks may be denied boarding or be punished by federal law."

  On social media, Kerry's violation of epidemic prevention regulations caused controversy.

American netizens said that this is a typical liberal hypocrite.

Someone else said: "My 6-year-old kid was kicked off the plane after putting the mask under his nose for 30 seconds. I want to ask who the executive order is for?"

  A spokesperson for "American Airlines" said: "We need to wear masks on our planes and we are investigating the matter."

  US Climate Envoy John Kerry responded on Wednesday that it was "short-lived."

"Please be clear: if I wear a mask on one ear during a flight, it is short-lived. I wear a mask because it saves lives and prevents spread. This is what science tells us to do," K Said.
