June 23 (UPI) -- Sen. Rand Paul, R-Ky., said he has subpoenaed Dr. Anthony Fauci after the former infectious diseases official backed out on an agreement to testify on the COVID-19 pandemic.

The Hill reported that this is the first subpoena issued by Paul as chairman of the Senate Homeland Security and Governmental Affairs Committee.

"Last week, Anthony Fauci notified us that he will not voluntarily testify before the Senate Homeland Security and Governmental Affairs Committee, even though he had previously agreed to do so," Paul wrote in a post on X on Tuesday. "Therefore, today we have issued a subpoena for him to publicly testify."

The post on X included a photo of Rand appearing to sign the subpoena.
