Another scientist involved in the proposal also says he doesn’t know if the work was done.
"To the very best of my knowledge ... the work hasn’t been done," Peter Daszak, president of the EcoHealth Alliance, told a congressional panel this week.
Mr. Daszak, however, admitted that he doesn’t know whether scientists at the Wuhan Institute of Virology (WIV) in China have done the proposed experiments.
"Do you know if the WIV started this work?" he was asked during a U.S. House of Representatives Select Subcommittee on the Coronavirus Pandemic hearing in Washington.
"No," Mr. Daszak replied.
"Then you can’t say that the work was not done," Mitch Benzine, the staff director for the panel, said.
"There is no evidence of the work being done. There is no evidence that WIV started it," Mr. Daszak said.
Has he ever asked Shi Zhengli, a top scientist at the WIV, whether she carried out the proposal?
"No," Mr. Daszak acknowledged.
The proposal in question, dubbed Project DEFUSE, was submitted in 2018 to the U.S. government as EcoHealth and its partners, including WIV, sought to take viruses from bats, reverse engineer them, and add features. Some outside scientists say the proposed work could have led to the creation of SARS-CoV-2, the virus that causes COVID-19.
The Defense Advanced Research Projects Agency (DARPA) declined to fund the proposal, expressing concerns that adding features to coronaviruses could create a dangerous virus.
After the proposal was leaked to the public in 2021, Mr. Daszak and EcoHealth have said definitively that the proposed experiments never took place.
"The DARPA proposal was not funded. Therefore, the work was not done. Simple," Mr. Daszak told The Intercept in 2022.
