CBS News 2020, May 1 - Trump says he's seen evidence virus started in Chinese lab

President Trump claimed Thursday he's seen evidence the new coronavirus originated in a Chinese lab and he threatened tariffs on Beijing over its role in the global pandemic. The president's assertion was undermined by his intelligence office and his top diplomat, who said, "We don't know precisely where it began."

Scientists believe the virus jumped from animals to humans, emerging in China late last year, possibly from a market selling exotic animals for meat.

But speculation has swirled about a top-secret lab, reinforced by internet rumors and right-wing radio hosts -- and increasingly taken up by Mr. Trump.
