The Central Intelligence Agency with a "low confidence" has changed its stance and concluded that it's likely the COVI-19 virus was leaked from a Chinese lab before it became a global pandemic five years ago.

Langley joins the FBI and Energy Department in agreeing that a lab leak is the most likely source of the pandemic.

It was unclear the extent to which the agency has collected new intelligence on COVID-19's origins and whether that new evidence was used to formulate the latest assessment.
