Asked about the grant materials, Robert Kessler, communications manager at EcoHealth Alliance, said, “We applied for grants to conduct research. The relevant agencies deemed that to be important research, and thus funded it. So I don’t know that there’s a whole lot to say.”

The grant was initially awarded for a five-year period — from 2014 to 2019. Funding was renewed in 2019 but suspended by the Trump administration in April 2020.

The closest relative of SARS-CoV-2, which causes Covid-19, is a virus found in bats, making the animals a focal point for efforts to understand the origins of the pandemic. Exactly how the virus jumped to humans is the subject of heated debate. Many scientists believe that it was a natural spillover, meaning that the virus passed to humans in a setting such as a wet market or rural area where humans and animals are in close contact. Biosafety experts and internet sleuths who suspect a lab origin, meanwhile, have spent more than a year poring over publicly available information and obscure scientific publications looking for answers. In the past few months, leading scientists have also called for a deeper investigation of the pandemic’s origins, as has President Joe Biden, who in May ordered the intelligence community to study the issue. On August 27, Biden announced that the intelligence inquiry was inconclusive.

Biden blamed China for failing to release critical data, but the U.S. government has also been slow to release information. The Intercept initially requested the proposals in September 2020.

“I wish that this document had been released in early 2020,” said Chan, who has called for an investigation of the lab-leak origin theory. “It would have changed things massively, just to have all of the information in one place, immediately transparent, in a credible document that was submitted by EcoHealth Alliance.”

The second grant, “Understanding Risk of Zoonotic Virus Emergence in Emerging Infectious Disease Hotspots of Southeast Asia,” was awarded in August 2020 and extends through 2025. The proposal, written in 2019, often seems prescient, focusing on scaling up and deploying resources in Asia in case of an outbreak of an “emergent infectious disease” and referring to Asia as “this hottest of the EID hotspots.”
