Anthony Fauci started his first day as NIAID director in 1984 knowing almost no one outside a small circle of infectious disease specialists. By May 2020, he was writing in his private diary that he had become “the most famous person in the country.” That pivot from obscurity to celebrity, captured in real time across 1,141 pages of personal notes, is just one thread in a document that also covers a fractured relationship with a sitting president, a war over television airtime, and a scientific debate about COVID’s origins that still hasn’t been fully resolved.
Senator Rand Paul released what he described as diary entries made by Fauci spanning December 2019 through December 2022, dropping them publicly in late July 2026 in the days before Fauci was scheduled to appear before a Senate committee. Paul released the private entries arguing that the writings prove Fauci discussed the origins of the virus differently in public from how he did in private. Fauci has denied that characterization.
The release stirred outrage among critics who accused Fauci of an obsession with fame and of contradicting himself during the COVID-19 pandemic. The document contains entries that support multiple readings – and that ambiguity is precisely what has made it so politically explosive.
Fauci’s Diary COVID Origins: What He Actually Wrote
The released documents show Fauci privately confronted possibilities about the virus’s origins that he publicly downplayed. In January 2020, Fauci wrote about the Huanan Seafood Wholesale Market in Wuhan, noting in his diary that “we know the market was not the source, it was the amplifier” – a distinction between where the virus first spread widely and where it actually originated.
In later diary entries, Fauci noted his own limitations on this specific topic, writing that since he was not an evolutionary biologist, he assembled a group of knowledgeable scientists together with Francis Collins, then NIH director, to examine the question. By May 2021, he wrote that he had “always said that the very highly likelihood is that the virus originated naturally from an animal reservoir jumping to a human” – but acknowledged that, given mounting speculation about a lab leak, he was saying no one was 100% certain of the origin, including himself, and was calling for a thorough investigation.
In July 2021, Fauci recounted a meeting with the National Security Council in which he strongly disagreed with the FBI‘s conclusion that the pandemic originated from a lab leak. That disagreement had legs. The FBI assessed that the coronavirus “most likely” emerged in a “lab incident in Wuhan.” In January 2025, the CIA issued its own assessment that a research-related origin was “more likely than a natural origin,” though it attached “low confidence” to that conclusion. Sitting on the other side of that debate, a WHO report from June 2025 concluded that “the weight of available evidence suggests zoonotic spillover” – meaning the virus jumped from animals to humans – either directly from bats or through an intermediate host. The science genuinely remains contested.
The Trump Relationship: From Flattery to Frustration
The diary’s portrait of Fauci’s relationship with Donald Trump is one of its most striking threads. Fauci privately complained about Trump’s “rambling” and reveled in media coverage of his own role, according to the personal diary entries.
The relationship had a warmer start. When Fauci first met Trump on January 29, 2020, Trump told him he was one of the smartest people he knew and called him “a famous guy.” That goodwill didn’t last. As the pandemic wore on, Fauci’s diary entries show his growing disillusionment, branding the president “rambling,” “crazy,” “desperate,” “bumbling,” “incompetent” and “a true embarrassment.” By March 29, 2021, Fauci wrote that Trump “is truly an obnoxious adolescent.”
Some of the most revealing entries concern Trump’s behavior in person compared to his public attacks. Fauci privately complained that Trump would tell reporters their relationship was fine, while simultaneously retweeting posts attacking him. The diary also records Trump’s COVID illness in real time. Fauci recounted a call from Trump’s then-Chief of Staff Mark Meadows when Trump was sick, and included details about Trump’s temperature, his oxygen level – which had dropped to worrying levels – and the decision to give the president an antiviral medication.
The Battle Over Airtime
Fauci’s relationship with White House Chief of Staff Mark Meadows deteriorated throughout the pandemic. Fauci wrote that Meadows threatened to keep him off television, repeatedly pushed him to soften his public messaging and, in one entry, recounted Meadows “screaming” over his public comments.
The war over Fauci’s television access played out through competing factions inside the White House. Fauci repeatedly described then-White House communications director Alyssa Farah as an ally during internal battles over media appearances. In one May 2020 entry, he wrote that Farah admitted White House staff had been “holding me back,” said the situation had “gotten out of hand” and promised to begin clearing his television requests again. Not everyone in the communications shop earned that kind of review. In a July 2, 2020 entry, Fauci called then-HHS Assistant Secretary for Public Affairs Michael Caputo “a con man who is completely full of sh–,” writing that Caputo publicly claimed to support his television appearances while privately blocking them.
The constant political pressure on Fauci’s messaging is relevant context for the broader debate over whether he contradicted himself during the pandemic. The diary shows that the public health messaging was not simply a reflection of the science – it was the output of a daily negotiation with political operatives who had their own calculations.
Fame, Threats, and the Cost of Visibility
Senator Paul released more than 1,000 pages of Fauci’s diaries, written while he advised the federal COVID response. Many of those pages document something that critics have seized on: Fauci’s apparent preoccupation with his own celebrity. In a May 2020 entry, he wrote that “it is not hyperbole to say that today I am the most famous person in the country.” He described the attention as explosive and really unimaginable.
The fame, though, came packaged with something darker. By August 2020, the same attention was triggering something far less flattering: Fauci wrote that the notoriety “is triggering increased hate mail and threats,” adding that “the far, extreme right and QAnon literally hate me.”
Those weren’t abstract concerns. In early April 2020, Fauci began receiving an increased security detail due to death threats against him and his family. The threat environment escalated to the point that, in 2021, Thomas Patrick Connally Jr. pleaded guilty to sending threatening emails to Fauci and his family. Federal protection continued for years after Fauci stepped down from his 38-year tenure as NIAID director in 2022 – until 2025, when Trump revoked his security detail entirely.
Fauci’s diary entries about fame sit uncomfortably alongside the entries about threats. A scientist logging death threats and a scientist tallying his television appearances appear on the same pages – sometimes in the same week. That juxtaposition is the document in miniature.

What the Diary Actually Tells Us
The diary is a primary source document written by one person, under significant stress, recorded in real time rather than edited for posterity. The entries about COVID’s origins reflect genuine scientific uncertainty – a January 2020 note about the Wuhan market being an “amplifier” rather than a source was written when almost no one had solid data. The entries about Trump document frustration that many senior public servants working through that period reported privately.
Fauci’s framing when Paul released the entries was blunt: “What [Fauci] wrote privately and what he told the country are two different stories.” Fauci’s defenders would argue the diary shows a scientist threading an impossible needle – navigating political operatives who wanted to control his airtime while trying to communicate evolving science in real time. His critics would argue it shows a man who prioritized his image and managed information strategically. Both readings are available in the same 1,141 pages. The diary documents show that pandemic-era public health decisions were made not in a vacuum of science, but inside a daily grind of political pressures, television negotiations, personal threats, and real uncertainty about the biology – and readers can draw their own conclusions from that record.
