White House Press Secretary Jen Psaki said on Monday the United States could not confirm a Wall Street Journal report on the origins of COVID-19 and needed more information.
Three researchers from China's Wuhan Institute of Virology (WIV) sought hospital care in November 2019, a month before China reported the first cases of COVID-19, the Wall Street Journal reported on Sunday, citing a US intelligence report.
Psaki said the United States hopes the World Health Organization can move into a more transparent investigation of the origins of the coronavirus pandemic.
