Dr. Anthony Fauci is an adviser to President Donald Trump and something of an American folk hero for his steady, calm leadership during the pandemic crisis. At least one poll shows that Americans trust Fauci more than Trump on the coronavirus pandemic—and few scientists are portrayed on TV by Brad Pitt.

But just last year, the National Institute for Allergy and Infectious Diseases, the organization led by Dr. Fauci, funded scientists at the Wuhan Institute of Virology and other institutions for work on gain-of-function research on bat coronaviruses.

In 2019, with the backing of NIAID, the National Institutes of Health committed $3.7 million over six years for research that included some gain-of-function work. The program followed another $3.7 million, 5-year project for collecting and studying bat coronaviruses, which ended in 2019, bringing the total to $7.4 million.

Many scientists have criticized gain of function research, which involves manipulating viruses in the lab to explore their potential for infecting humans, because it creates a risk of starting a pandemic from accidental release.
