Senior Biden officials finding that Covid lab leak theory as credible as natural origins explanation

Senior Biden administration officials overseeing an intelligence review into the origins of the coronavirus now believe the theory that the virus accidentally escaped from a lab in Wuhan is at least as credible as the possibility that it emerged naturally in the wild -- a dramatic shift from a year ago, when Democrats publicly downplayed the so-called lab leak theory.

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.
