Senate subcommittee has released their report on SARS-COVID-2 origin (report linked above).
Here is a couple of quotes from the report:
Basis for Assessment that Research-Related Incident is More Likely Origin of SARS-CoV-2
Nearly three years after the COVID-19 pandemic began, substantial evidence demonstrating that the COVID-19 pandemic was the result of a research-related incident has emerged. A research-related incident is consistent with the early epidemiology showing rapid spread of the virus in Wuhan, with the earliest calls for assistance being located in the near the WIV’s original campus in central Wuhan.207 It also explains the low genetic diversity of the earliest known SARS-CoV-2 human infections in Wuhan, because the likely index case, would be an infected researcher, is the likely primary source of the virus in Wuhan.208 A research-related incident also explains the failure to find an intermediate host as well as the failure to find any animal infections pre-dating human COVID-19 cases.209
Conclusion
As noted by the WHO Scientific Advisory Group for the Origins of Novel Pathogens, the COVID19 Lancet Commission, and the U.S. Office of the Director of National Intelligence 90-Day Assessment on the COVID-19 Origins, more information is needed to arrive at a more precise, if not a definitive, understanding of the origins of SARS-CoV-2 and how the COVID-19 pandemic began.225 Governments, leaders, public health officials, and scientists involved in addressing the COVID-19 pandemic and working to prevent future pandemics, must commit to greater transparency, engagement, and responsibility in their efforts. Based on the analysis of the publicly available information, it appears reasonable to conclude that the COVID-19 pandemic was, more likely than not, the result of a research-related incident. New information, made publicly available and independently verifiable, could change this assessment. However, the hypothesis of a natural zoonotic origin no longer deserves the benefit of the doubt, or the presumption of accuracy. The following are critical outstanding questions that would need to be addressed to be able to more definitively conclude the origins of SARS-CoV-2: • What is the intermediate host species for SARS-CoV-2? Where did it first infect humans? • Where is SARS-CoV-2’s viral reservoir? • How did SARS-CoV-2 acquire its unique genetic features, such as its furin cleavage site? Advocates of a zoonotic origin theory must provide clear and convincing evidence that a natural zoonotic spillover is the source of the pandemic, as was demonstrated for the 2002-2004 SARS outbreak. In other words, there needs to be verifiable evidence that a natural zoonotic spillover actually occurred, not simply that such a spillover could have occurred.
