On Thursday's broadcast of NewsNation's "On Balance," Atlantic Council Senior Fellow Jamie Metzl discussed newly-released messages by authors of the "Proximal Origin of SARS-CoV-2" article arguing against the lab leak origin theory of COVID-19 that showed that some of the authors of the paper actually viewed the lab leak as more probable than the paper indicated and stated that some scientists dismissed the lab leak theory because they "had basically invested their careers in the idea that there were going to be more pandemics and that one of the most important ways of preventing those was to foster scientific collaborations across borders." And they didn't want to be seen as "supporting a conservative Republican narrative."
