Problem is there is no real way to know if a virus is engineered due to commonly used splicing techniques that leave no imprinting. The argument used was it's not how they would alter the virus if their own labs. Additionally a lot of research is done through serial passaging which is done by passing the virus through host species as it adapts naturally kind of like selective breeding. In fact serial passaging techniques were originally used to make an airborne version of the extremely deadly H5N1 virus(bird flu) which triggered a temporary ban during the Obama Administration https://www.science.org/content/article/exclusive-controversial-experiments-make-bird-flu-more-risky-poised-resume https://www.science.org/content/article/exclusive-controvers...
