A report from the State Department was issued during the last days of former President Donald Trump's administration but officials familiar with the report did not agree on the strength of the evidence found, the Journal reported. In March, Marion Koopmans, a dutch virologist, told NBC News the illness of lab workers could be attributed to regular seasonal illnesses. Earlier this year, a team from the World Health Organization spent a month in Wuhan investigating the origin of the virus and concluded that the virus most likely jumped from bats to people. The group said a lab leak was "extremely unlikely."
The WHO said it also did not have access to all the necessary information. That lack of information has prompted some experts to be wary of the findings and demand more investigations into the virus's origin, including the possibility that it in fact was leaked from a lab.
