Washington (CNN)Over the weekend, Republican Sen. Tom Cotton came under fire for a series of comments and tweets on the coronavirus. On Fox News Sunday morning, Cotton suggested the virus did not originate in an animal market as the Chinese government has claimed, but perhaps from another source, such as an infectious disease research lab nearby. While acknowledging there’s no evidence the disease originated there, Cotton questioned the validity of China’s statements, saying “China was lying from the beginning, and they’re still lying today.”
