Mike Pompeo says 'enormous evidence' coronavirus originated in Wuhan lab

US Secretary of State Mike Pompeo has said there was "enormous evidence" that the coronavirus pandemic originated in a laboratory in Wuhan, China.

"There is enormous evidence that this is where it began," the US secretary of state said on ABC's "This Week."

"These are not the first times that we've had a world exposed to viruses as a result of failures in a Chinese lab," Pompeo added, pointing at China's "history of running substandard laboratories."

He stressed that he had no reason to believe that the virus was deliberately spread but he ramped up already harsh U.S. criticism of the Chinese for their response to the outbreak.
