The U.S. National Security Adviser Jake Sullivan, says that it is imperative that the WHO report on the origins of the virus be "independent" and "free from alteration by the Chinese government." This echoes earlier concerns of the Trump administration and of president Trump who made the decision to quit WHO on this issue.
Sullivan noted that "reengaging with the WHO also means holding it to the highest standards. We have deep concerns about the way in which the early findings of the Covid 19 investigation were communicated, and questions about the process used to reach them."
