Biden signs bill to declassify information on Covid-19 origins

US President Joe Biden signed a bill that requires Director of National Intelligence Avril Haines to declassify information related to the origins of Covid-19, the White House has said. "In implementing this legislation, my administration will declassify and share as much of that information as possible, consistent with my constitutional authority to protect against the disclosure of information that would harm national security," Biden said in a statement.
