Fauci Diaries Slam Covid Lab Leak Claims as Nonsense 2026

Anthony Fauci's newly released diaries describe a Covid-19 lab leak investigation by journalist Sharri Markson as a bunch of nonsense, sparking fresh debate over pandemic origins. The former top US medical adviser, now 85, faced a Senate hearing subpoenaed by Republican Senator Rand Paul, who has long championed the lab leak theory. Fauci's private journal entries, published ahead of his testimony, directly criticize Markson's reporting in The Australian and her book claiming Wuhan experiments with bat coronaviruses.

Fauci's Diaries and the Lab Leak Controversy

In his pandemic-era journal, Fauci wrote that Markson's May 2021 article about Chinese military scientists discussing weaponized coronaviruses "does not make any sense." He questioned why anyone would create an agent that could infect their own population, calling the report flawed. Guardian Australia later revealed the "chilling" document cited in the article was based on a discredited 2015 book of conspiracy theories freely available online.

Senate Hearing and Rand Paul's Campaign

At Wednesday's hearing, Fauci refused to answer questions, accusing Paul of an "unhinged" campaign lobbying for his imprisonment. Paul published 1,141 pages of Fauci's journal entries ahead of the session, continuing his years-long push for the lab leak theory. Fauci, who served under seven presidents, retired in 2022 after leading the National Institute of Allergy and Infectious Diseases.
