Dr Anthony Fauci, the US’s chief medical adviser at the start of the pandemic, has described a book by News Corp investigative journalist Sharri Markson backing the “lab leak” theory of Covid-19’s origins as a “bunch of nonsense” in his newly released diaries.

This week, Fauci, 85, was subpoenaed by the Republican senator Rand Paul to appear at a Senate hearing into Covid-19 and his handling of the pandemic.

Six years on from Covid crisis, Republicans still politicizing science – and Fauci remains a political punching bag

A US Senate committee hearing featuring Dr Anthony Fauci revealed at least one certainty: six years after the pandemic, politicizing science remains a vital political tactic.

More than 155 scientists, physicians and public health advocates have called for an end to what they describe as the “vilification and harassment of many American scientists” by the Trump administration and its allies.

Former top US health official wrote about challenging interactions with publicity-fixated Trump during Covid

Diary entries released by a Republican senator in an attempt to damage Anthony Fauci also show the former top US government science adviser’s growing disillusionment with Donald Trump in the first year of the Covid-19 pandemic, branding the president “rambling”, “crazy”, “desperate”, “bumbling”, “incompetent”, “an idiot”, “a true embarrassment”, “totally nuts” and “truly an obnoxious adolescent”.

From the earliest days of the crisis six years ago, Fauci noted in his journal challenging interactions with the publicity-fixated Trump. On 27 February 2020, amid the first stirrings of public alarm, he wrote of a surprise late-night call, in which the US president “wanted to chat about the coronavirus situation in general”.
