WASHINGTON (Reuters) - U.S. President Donald Trump said on Wednesday his government is trying to determine whether the coronavirus emanated from a lab in Wuhan, China, and Secretary of State Mike Pompeo said Beijing "needs to come clean" on what they know.

The source of the virus remains a mystery. General Mark Milley, chairman of the Joint Chiefs of Staff, said on Tuesday that U.S. intelligence indicates that the coronavirus likely occurred naturally, as opposed to being created in a laboratory in China, but there is no certainty either way.
