A group of Chinese virologists released a strange new paper on Monday that claims the new coronavirus was engineered in a Chinese lab. One of the virologists, Li-Meng Yan, told the Fox News host Tucker Carlson it was a "man-made virus" that the Chinese government released "intentionally." Yan and her coauthors work for groups cofounded by the former Trump strategist Steve Bannon. He directed the groups before his arrest in August. Some members of the Trump administration have pushed a fringe theory that the virus accidentally leaked from a lab in Wuhan, China, but there's no evidence of this.
