The CIA has shifted its stance about the origin of the virus that causes Covid-19, NBC News reported on Saturday. The intelligence agency now believes that the coronavirus escaped from a Chinese lab, a shift from its previous stance, in which it did not take a position.

“CIA assesses with low confidence that a research-related origin of the COVID-19 pandemic is more likely than a natural origin based on the available body of reporting,” a CIA spokesperson said in a statement to NBC News.

“CIA continues to assess that both research-related and natural origin scenarios of the COVID-19 pandemic remain plausible.”

The move comes one day after John Radcliffe, the new director of the CIA, was confirmed. He said on Friday in an interview that he believes U.S. intelligence and science points to the origin of Covid being an accidental release, or “lab leak,” from the Wuhan Institute of Virology, a research institution in Wuhan, China, where the outbreak was first observed in late 2019.
