Coronavirus: Was US money used to fund risky research in China?

It's linked to the unproven theory that the virus could have leaked from a lab in Wuhan, the Chinese city where it was first detected.

A report released by Republican lawmakers cites "ample evidence" that the lab was working to modify coronaviruses to infect humans and
calls for a bipartisan investigation into its origins.

Republican Senator Rand Paul also alleges that US money was used to fund research there that made some viruses
more infectious and more deadly, a process known as "gain-of-function".

But this has been firmly rejected by Dr Anthony Fauci, the US infectious diseases chief.
