I don't know, I get frustrated by these arguments. I think that it's much ado about nothing. Just to summarize, yes Fauci told the Senate that the NIH did not
directly fund gain-of-function research in Wuhan. If you read what he said exactly, his statements are accurate according to how the NIH defines gain of function research. However, if you read the comments from the senators seeking to shift emphasis away from fixing the economy and Iran, Senator Paul uses a broader definition of gain-of-function. And this is most brain cells that I'm going to waste on this topic.
Yes, he didn't directly do it. That doesn't mean he didn't do it at all.
Six year old news articles aren't easy to find, especially with his current testimony flooding the results, but he did say he didn't direct any funding while doing so, which is perjury. There is apparently dispute over whether it was banned or not, but even if it wasn't doing so with China can't be a good idea.
I personally think his extreme measures to fight a cold and advocating a lockdown of the country were criminal too, but that's more a "crime against humanity" instead of a "breaking a federal statute" criminality.
