Still, more than halfway into President Joe Biden's renewed 90-day push to find answers, the intelligence community remains firmly divided over whether the virus leaked from the Wuhan lab or jumped naturally from animals to humans in the wild, multiple sources familiar with the probe told CNN. Little new evidence has emerged to move the needle in one direction or another, these people said. But the fact that the lab leak theory is being seriously considered by top Biden officials is noteworthy and comes amid a growing openness to the idea even though most scientists who study coronaviruses and who have investigated the origins of the pandemic say the evidence strongly supports a natural origin. Current intelligence reinforces the belief that the virus most likely originated naturally, from animal-human contact and was not deliberately engineered, the sources said. But that does not preclude the possibility that the virus was the result of an accidental leak from the Wuhan Institute of Virology, where coronavirus research was being conducted on bats -- although many scientists familiar with the research say such a leak is unlikely.
