Biden asks the CIA to investigate the Covid laboratory theory

I kind of feel sorry for the CIA. The US intelligence agency has vast resources but until now has come up with no definitive proof that Covid-19 escaped from or was leaked from China's institute of virology in Wuhan. Yet Joe Biden has now asked them to have another go because of the revelation which incidentally the intelligence boys knew about, that three employees at the institute had fallen very sick in November 2019 and had been hospitalised. You wonder what more the CIA can do to get further proof. Unless they manage somehow to interview the three institute employees, assuming they didn't die from their sickness. But the Chinese security authorities are going to be on high alert for any sign of a CIA type skulking around the institute or asking questions in Wuhan. So unless they get a lucky break and some signals intelligence satellite picks up a couple of Chinese virology chaps chatting in a bar about their poor colleagues who started the whole pandemic off, it's hard to imagine how Biden is going to get any fresh intel that could enable him to join Donald Trump in accusing Beijing of being responsible for the worldwide health crisis. And even if they do find something new, Beijing will just deny its veracity and will accuse Biden of stoking up old and false news. But perhaps I'm underplaying the CIA's capabilities. Maybe somewhere in Wuhan there is a "source" who will tell all. But I sincerely doubt it. Who in Wuhan of all places is going to reveal anything which might be traced back to them. When the virus started racing around Wuhan, Chinese security honchos went around knocking on people's doors to make sure they had daren't to venture out. Lockdown in China meant total lockdown or else. So, good luck CIA. I'll wait with bated breath. As will Biden no doubt.
