US President Donald Trump said that his country will definitely report on the origin of COVID-19 soon.
He also said that China should have informed the US about the virus.
He added that Dr Anthony Fauci, the director of the U.S. National Institute of Allergy and Infectious Diseases and a key member of the White House coronavirus task force, will testify before a Senate panel.
Earlier, Trump and members of his administration claimed they had evidence that the coronavirus was deliberately released from a laboratory in Wuhan. Beijing has strongly rejected the allegations.
