Washington: President Joe Biden on Monday signed into law a bill requiring the release of intelligence materials on potential links between the outbreak of the Covid pandemic and a laboratory in the Chinese city of Wuhan.

"We need to get to the bottom of Covid-19's origins..., including potential links to the Wuhan Institute of Virology," Biden said in a statement. "In implementing this legislation, my administration will declassify and share as much of that information as possible."
