Dr. Anthony Fauci, the director of the U.S. National Institute of Allergy and Infectious Diseases said there is no scientific evidence the new coronavirus, SARS-CoV-2, was made in a Chinese laboratory in an interview with National Geographic Monday.

Fauci's statement contradicts U.S. President Donald Trump's remarks that he had seen convincing evidence that the coronavirus originated from China's Wuhan Institute of Virology (WIV). 

When pressed for details, Trump said: "I can't tell you that. I'm not allowed to tell you that."

On Sunday, U.S. Secretary of State Mike Pompeo said he'd seen "enormous evidence" supporting the theory, but didn't elaborate.

When asked about the assessment from the U.S. intelligence community, concluding the "COVID-19 virus was not manmade or genetically modified," Pompeo concurred. "That’s right. I agree with that," he said.

The Director of U.S. National Intelligence did not disclose evidence either, but issued a statement dismissing any suggestion the germ had been engineered. "The Intelligence Community also concurs with the wide scientific consensus that the COVID-19 virus was not manmade or genetically modified."

The World Health Organization reached the same conclusion. "All available evidence suggests the virus has an animal origin and is not a manipulated or constructed virus in a lab or somewhere else," WHO spokeswoman Fadela Chaib said.

The WHO said the U.S. hasn't shared any evidence linking coronavirus to Chinese lab. It said on Monday that from all the evidence they have, the virus is of natural origin. 

The Chinese Ambassador to the United States, Cui Tiankai, said the place where the virus was first reported may not be its place of origin. "It seems like both the United States and countries in Europe have found earlier cases than China did,"  Cui said in a Tuesday interview with CGTN. "And we need scientists to figure that out,"  he added.

The Chinese Ambassador dismissed claims the virus originated in a Wuhan lab, or was manmade. Cui has been urging the United States to stop the blame game and cooperate in a worldwide effort to combat COVID-19. 

"Let's work together to respond to this global crisis, to save people's lives, to save the future of global economy, and to save the future of the global community,"  he said. "This is our paramount task," Cui said.
