In an interview on Fox News' "Sunday Morning Futures," Paul announced the National Institutes of Health "admitted" funding the Wuhan Institute's manipulation of viruses that "became more dangerous. That's a gain of function. They gained lethality."
"If this came out of the lab in Wuhan, what if a worse virus comes out of the lab?" he asked.

Paul referred to a commentary in The Washington Post by MIT Assistant Professor Kevin Esvelt, warning that manipulating viruses that risk provoking pandemics is too risky to allow.
"There hasn't been one hearing," Paul stated. "I've been asking Democrats to have a hearing on gain-of-function research so this doesn't happen again. You know, we do this research in the United States. This is a big, big question. This disease we're facing has a 1% mortality. What if we got a contagion that has a 50% mortality? They're actually doing experiments as we speak with viruses that have 50% mortality. That shouldn't be happening."

"Democrats love Dr. [Anthony] Fauci so much that they will not have one hearing to investigate the origins of this virus," he continued.

Last week, the NIH issued a letter that Paul says shows the NIH was funding the controversial research in Wuhan. "In virology, 'gain of function' refers to a kind of mutation that occurs in an altered gene product that possesses a new molecular function or a new pattern of gene expression," according to the National Center for Biotechnology Information.

Paul maintained that the Director of the National Institute of Allergy and Infectious Diseases, Dr. Anthony Fauci, should "absolutely" be dismissed and will never admit he potentially lied about the NIH's potential funding of gain-of-function research.

He announced that Congress would call for hearings to investigate the origins of the virus and get to the bottom of whether gain-of-function research at the WIV played a part. "Particularly, since this research still goes on," Sen. Paul said in the interview.

"We have no idea whether [the virus] gains functions, or loses function, that's what the experiment is," Paul explained to Axios. "But I don't know how anybody could argue that it's not gain-of-function research."
The NIH called the findings released in its letter "unexpected," though determined the research didn't meet its threshold to be reviewed and possibly terminated because the viruses used in the NIH funded research had not "shown to infect humans and the experiments were not reasonably expected to increase transmissibility or virulence in humans."
