The U.S. doctor doesn't believe the coronobius came from a Chinese laboratory.

In an interview for National Geographic, the top American expert on infectious diseases and a member of the White House group explained that “if you look at the evolution of the virus on the bats and what it now has, scientific evidence is powerful in the direction that the virus could not be artificially or deliberately manipulated”.

Secretary of State Mike Pompeo reiterated the White House's stance, that there is significant evidence that the virus comes from a Chinese laboratory.

Beijing has always denied, and some states have also voiced doubts about the transparency of Chinese authorities in managing this crisis.
