Senator Rand Paul is still aiming to take down Dr. Anthony Fauci—or have a new law passed to regulate gain-of-function research.

The Republican from Kentucky appeared on The Will Cain Podcast this week and spoke about how Fauci, the former chief White House medical adviser, allegedly committed crimes related to the COVID-19 pandemic.

“He lied to Congress, that’s a felony,” Paul said while speaking about Fauci. “I’ve referred him for prosecution, and [Attorney General] Merrick Garland has responded saying he got our letter, but there’s been no investigation as we know of.

“We know he lied, not because I say so but because his private emails contradict his public statements,” Paul said. “To me, culpability is important, but I don’t have control, I can’t prosecute…but the other thing I want to have happen is, I want this type of research that we’re paying for through our tax dollars to be circumscribed, to be regulated, to have a real committee of scientists looking at what is worthwhile, what is not worthwhile.

“So I’m not giving up on this til we either get culpability and/or a new law that says we can’t do this research without more oversight,” the senator said.
