When Carlson asked her why she believes the virus made it's way out of the Wuhan lab, Dr. Yan said "I worked in the WHO reference lab, which is the top coronavirus lab in the world at the university of Hong Kong. And the things I got deeply into such investigation in secret from the early beginning of this outbreak - I had my intelligence through my network in China, involved in the hospitals, institutes and also government."

"Together with my experience, I can tell you - this is created in a lab."

Dr. Yan fled Hong Kong on April 28 on a Cathay Pacific flight to the United States. She believes her life is in danger, and that she can never go back home.

"The reason I came to the U.S. is because I deliver the message of the truth of COVID," Yan told Fox News in July.
