Dear Chairman Peters and Ranking Member Portman:
On June 3, I wrote to request that the Homeland Security and Governmental Affairs Committee hold a hearing or
series of hearings on the public health and security risks posed by gain-of-function research. I write today to
renew that request in light of the recent admission by the National Institute of Health that it had indeed funded
gain-of-function research at the Wuhan Institute of Virology, despite Administration testimony to Congress to the
contrary.
Gain-of-function research aims to predict future naturally-occurring pandemics by enhancing the severity or
transmissibility of viruses that may infect humans. In an October 6 op-ed in the Wall Street Journal, Dr. Kevin
Esvelt of the Massachusetts Institute of Technology bluntly stated, "[t]o discover many dangerous viruses, or
learn to enhance weaker ones, is to share the blueprints for an arsenal of plagues." He went on to say that "such
research looks like a gamble that civilization can't afford to risk." I could not agree more.
The dangers posed by this kind of research are so acute that under President Obama, the National Institutes of
Health suspended funding for all gain-of-function projects for three years. The Senate recognized these risks in
May when it passed my amendment #2003 to S. 1260, the United States Innovation and Competition Act, by a
voice vote. Your assistance was crucial in crafting that amendment, which sought to restrict the use of U.S.
federal funds for gain-of-function research.
I renew my request that the Homeland Security and Governmental Affairs Committee promptly schedule a
hearing or series of hearings on gain-of-function research. I look forward to your timely response to this request.
Sincerely,
Rand Paul, M.D.
United States Senator
