Sen. Rand Paul (R-Ky.) issued a subpoena on June 23, 2026 [1], compelling Dr. Anthony Fauci to testify before the U.S. Senate.

The move signals an escalation in the long-standing dispute over the origins of the COVID-19 pandemic. It reflects ongoing congressional efforts to determine if federal officials suppressed information regarding the start of the global health crisis.

According to the subpoena, the Senate seeks testimony regarding the origins of COVID-19, and the alleged cover-up of U.S. involvement in gain-of-function research. The legal order follows a period in which Dr. Fauci declined to appear before the committee voluntarily.

Paul has previously questioned the transparency of the public health response and the funding of research in Wuhan, China. The subpoena aims to force a public accounting of the communication between U.S. health agencies and international researchers.

Dr. Fauci has not provided a public response to the subpoena as of Wednesday. The Senate committee intends to use the testimony to examine whether the U.S. government provided funding for research that could have led to the virus's emergence.

This legal action follows years of political friction between the former director of the National Institute of Allergy and Infectious Diseases and members of the Senate. The inquiry focuses on the definition of gain-of-function research, and whether those definitions were manipulated to avoid oversight.

Sen. Rand Paul (R-Ky.) issued a subpoena on June 23, 2026, compelling Dr. Anthony Fauci to testify.

The use of a subpoena indicates that voluntary cooperation between the legislative branch and former public health officials has broken down. By focusing on gain-of-function research, the committee is attempting to establish a legal and administrative trail that links U.S. funding to the laboratory origins theory, a move that could lead to further legislative restrictions on virological research.
