 So unfortunately, because of China's cover up, we'll never know with 100% certainty what actually took place. As Dr. Redfield said at one time, it's going to take the intelligence community to figure this out because China is not going to be cooperative. But several of the agencies have leaned towards lab leak and lean more and more heavily. And I think you may even see that change some more for other agencies as they become more aware of some of the things that were out there.
