Top officials from the administration of U.S. President Joe Biden have expressed concern about the way a pivotal report examining the origins of the COVID-19 pandemic was crafted, including the possibility that the Chinese government had a hand in writing it.

The Geneva-based World Health Organization has said the findings from its mission to Wuhan, China, in early 2021 will be ready in a few days. The report had been expected earlier in March.

The U.S. has "real concerns about the methodology and the process” of the report, including that the Chinese government "apparently helped to write it,” Secretary of State Antony Blinken said on CNN.
