After Bloom described his research, the Zoom meeting became “extremely contentious,” he wrote. Andersen leapt in, saying he found the preprint “deeply troubling.” If the Chinese scientists wanted to delete their sequences from the database, which NIH policy entitled them to do, it was unethical for Bloom to analyze them further, he claimed. And there was nothing unusual about the early genomic sequences in Wuhan.

Instantly, Nielsen and Andersen were “yelling at each other,” Bloom wrote, with Nielsen insisting that the early Wuhan sequences were “extremely puzzling and unusual.”

Andersen—who’d had some of his emails with Fauci from early in the pandemic publicly released through FOIA requests—leveled a third objection. Andersen, Bloom wrote, “needed security outside his house, and my pre-print would fuel conspiratorial notions that China was hiding data and thereby lead to more criticism of scientists such as himself.”

Fauci then weighed in, objecting to the preprint’s description of Chinese scientists “surreptitiously” deleting the sequences. The word was loaded, said Fauci, and the reason they’d asked for the deletions was unknown.

That’s when Andersen made a suggestion that surprised Bloom. He said he was a screener at the preprint server, which gave him access to papers that weren’t yet public. He then offered to either entirely delete the preprint or revise it “in a way that would leave no record that this had been done.” Bloom refused, saying that he doubted either option was appropriate, “given the contentious nature of the meeting.”

At that point, both Fauci and Collins distanced themselves from Andersen’s offer, with Fauci saying, as Bloom recalled it, “Just for the record, I want to be clear that I never suggested you delete or revise the pre-print.” They seemed to know that Andersen had gone too far.
