"Biden signs bill to declassify intelligence on potential Covid and Wuhan lab links"

US President Joe Biden has signed a bill requiring the release of intelligence materials on potential links between the Covid-19 pandemic and a laboratory in Wuhan, China. The move poses political risks for Biden, who is negotiating a difficult relationship with Chinese leader Xi Jinping. Beijing vehemently rejects the possibility that a leak during research at the Wuhan lab could have unleashed the global pandemic. The Covid-19 outbreak was first detected in 2019 in the eastern Chinese city of Wuhan, leading to almost 7 million deaths worldwide so far, according to official counts, with over a million of them in the US.
