Jack Phillips reports for the Epoch Times about one former federal health official’s criticism of a high-profile colleague.

Former Centers for Disease Control and Prevention (CDC) Director Robert Redfield rejected White House adviser Anthony Fauci’s claims that it’s more likely COVID-19 originated naturally.

In a recent interview, Fauci said he has an “open mind”  but still believes that the virus occurred naturally after previously dismissing the theory that it emerged from the Wuhan Institute of Virology in late 2019. “It looks very much like this was a natural occurrence, but you keep an open mind,” Fauci said.

When asked about Fauci’s recent comments on Monday, Redfield told Fox News that he still suspects COVID-19 emerged “from the laboratory” and “had to be educated in the laboratory to gain the efficient human-to-human transmission capability that it has.”

“There’s very little evidence, if you really want to be critical, to support” the natural emergence theory, he said. The former Trump administration official then compared COVID-19 to prior coronaviruses such as Middle Eastern Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS) that emerged about 10 years ago, saying that neither virus had the same transmission capacity as COVID-19.

“So it’s really exceptional that this virus is one of the most infectious viruses for man. And I still argue that’s because it was educated how to infect human tissue,” Redfield told Fox News.

The same Wuhan laboratory, he added, was the subject of a 2014 report amid claims that researchers performed research on bat-borne viruses that could impact humans.

“I’m disappointed in the [National Institutes of Health] for not leading an objective evaluation from the beginning,” Redfield told the outlet. “I think it really is antithetical to the science where they took a very strong position that people like myself who are somehow conspiratorial just because we have a different scientific hypothesis.”
