Biden calls for U.S. intelligence agencies to ‘redouble’ investigative efforts into the origins of the virus.

President Biden on Wednesday asked U.S. intelligence agencies to “redouble their efforts” to determine the origins of the coronavirus, saying in a statement that he was calling for a broad government report that incorporated findings from American labs and other federal agencies on whether the virus was accidentally leaked from a lab or transmitted by an animal to humans.

He asked intelligence officials to report back to him in 90 days on the results of their work and to keep Congress “fully apprised.”

Mr. Biden’s statement came as top health officials renewed their appeals this week for a more rigorous investigation into the origins of the virus, as the World Health Organization faced mounting criticism for an earlier report dismissing the possibility that it had accidentally escaped from a Chinese laboratory.
