Senator Marshall Reacts to Dr. Fauci and Former NIH Dir. Collins Reversal on Legitimacy of Covid-19 Lab Leak Theory 

Washington, D.C. – Last week, former National Institute of Allergy and Infectious Diseases (NIAID) Director Anthony Fauci and former National Institutes of Health Director Francis Collins both admitted that Covid-19 could have originated in a laboratory in Wuhan, China. Their statements, which were made in separate closed-door interviews with the House Select Committee on Coronavirus Pandemic, marks a key reversal from the pair’s previous stance dismissing the lab leak theory.

Senator Roger Marshall, M.D., who has been leading investigations into the Covid-19 origins, released the following statement addressing Dr. Fauci’s and Dr. Collins’s new bombshell confessions that the Covid-19 lab leak theory is legitimate:

“A million Americans died from the Covid-19 virus in an era that will always be remembered as one of the darkest chapters in our nation’s history,” Senator Marshall said. “The idea that the NIH Director, Dr. Collins, and Dr. Fauci would lie to the American people, including those families still mourning the loss of their loved one, in order to protect their own reputation and cover up their own mistakes is disgraceful. These people are frauds, and there must be consequences that fit the crime.” 

“Even before this virus landed on American soil, I sounded the alarm, asking for answers and following the money,” Senator Marshall continued. “They vilified me, my colleagues on the Doctors Caucus, and anyone who started to put the pieces together. I was not afraid of taking on the Gain of Function Mafia then, and I am not afraid now. We will keep fighting to expose the malpractice that happened in the Wuhan Institute of Virology lab in the Fall of 2019, which resulted in millions of deaths worldwide, to ensure it can never happen again.”


Dr. Fauci and Dr. Collins have favored the theory that the birth of Covid-19 was a natural occurrence and have previously publicly denied the possibility it could have originated in a laboratory. In fact, former NIH Dir  Dr. Collins called the lab leak theory a “conspiracy theory” and Dr. Fauci said, “what evidence do we have as evidence that it’s a lab leak? Nothing.

In 2023, the Department of Energy joined the Federal Bureau of Investigation as the second federal intelligence agency to take the position that a lab leak was the most likely origin of Covid-19.

Senator Marshall has been a leader in investigating the origins of Covid-19. He was the first member of Congress to sound the alarm on Covid origins on the House floor in 2020 and has been investigating ever since. 

  • In response to tough questions from Senator Marshall about his involvement in gain of function research, Dr. Fauci called Senator Marshall a “moron.
  • In April 2023, Senator Marshall published the bombshell Muddy Waters report, which details evidence that lab leaks in Wuhan, China are responsible for Covid-19’s origin. 
  • Additionally, Senator Marshall has introduced legislation and written letters seeking a pause on federally sponsored gain of function research until proper safeguards are in place.
