Former president Donald Trump attacked the nation's top infectious disease expert, Dr. Anthony Fauci, over private emails released from the pandemic's early stages.

In a statement released on Thursday, June 3, Donald Trump also called on China to pay $10 trillion to the U.S. over the COVID-19 pandemic, according to The Blaze report. 

The former president said China should pay the U.S. and the rest of the world "for the death and destruction they have caused."

Donald Trump noted that the correspondence between Anthony Fauci and China "speaks too loudly for anyone to ignore."

Trump was pointing out to the increasing number of experts, saying that there was evidence proving to the possibility that the coronavirus might have originated in a laboratory, instead of coming from natural causes.

The lab leak theory was reportedly identified as a conspiracy by mainstream media and several experts until reports of supposed evidence emerged.

Donald Trump continued to slam Anthony Fauci, saying that he did not have enough faith in vaccines to fight the pandemic. He also attacked the infectious disease expert on his changing stance on the use of face masks.

White House Defends Dr. Anthony Fauci

The White House has defended Anthony Fauci amid the recently released work emails of the infectious disease expert.

White House Press Secretary Jen Psaki had been an undeniable asset in the U.S. response to the pandemic response of the nation, BBC News reported. Anthony Fauci also said that the email exchange regarding the virus lab leak theory was being taken out of context.

President Joe Biden has ordered a review on the matter despite having no concrete proof that the coronavirus had come from a lab.

Allies of the U.S. National Institutes of Health infectious disease specialist said that Fauci's messages show nothing more than a dedicated public servant going through the early days of the pandemic.

However, critics are suggesting that Fauci may have done a cover-up, further claiming that he perjured himself in testimony to Congress.

Anthony Fauci noted that the idea is quite farfetched that the Chinese had intentionally created something that could kill them, as well as other people.

The more than 3,000 pages of emails were obtained by The Washington Post and BuzzFeed News through the Freedom of Information Act that allows media to request internal government correspondence.

In a January 2020 email to Fauci, the director of the country's largest biomedical research facility suggested the virus' "unusual features" that may indicate it is "engineered." It prompted Fauci to say he will reach out via phone.

The director of the National Institute of Health, Francis Collins, sent Fauci an email with the subject line "conspiracy gains momentum" in April 2020. Fauci's response to this is fully redacted.

Last month, Anthony Fauci noted that he was "not convinced" that the coronavirus originated naturally. He also expressed support for an investigation.

Wuhan Lab Leak Theory

There were suspicions that the coronavirus may have leaked accidentally or otherwise, from a laboratory in the city of Wuhan in China.

Wuhan had reported the first virus infection, according to another BBC News report. The theory had once again gained traction after U.S. media have raised new concerns over the lab leak theory.

Some scientists who were once skeptical of the theory have expressed new opinions when it comes to the issue. One classified U.S. intelligence report stated that three researchers at the Wuhan laboratory were treated in a hospital in November 2019. This was before the virus had started infecting humans in the city.

A World Health Organization (WHO) investigation was supposed to clear the air regarding the matter. However, many experts claimed that it produced even more questions than answers.

This year, WHO-appointed scientists had gone to Wuhan to investigate the source of the pandemic. Twelve days of being in the country, the WHO team concluded that the laboratory leak theory was extremely unlikely.

The WHO's director-general Dr. Tedros Adhanom Ghebreyesus called for a new investigation. He said that all hypothesis should remain open and require more study.
