Secretary of State Mike Pompeo on Sunday stepped up a US campaign to hold China accountable for the spread of the deadly coronavirus, asserting there is “enormous evidence” the virus originated in a laboratory in the city of Wuhan. The high-security bio-containment facility, the Wuhan Institute of Virology, has called such claims “impossible”. Pompeo, speaking on ABC’s “This Week,” did not elaborate on what he also described as “significant amounts of evidence”.
