The United States has 'deep concerns' about China's early response to the Covid-19 crisis and wants Beijing to "make available its data from the earliest days of the outbreak," national security advisor Jake Sullivan said Sunday. The statement came days after a World Health Organization team of inquiry returned from Wuhan, China, the epicenter of the pandemic, and suggested the virus might have originated with frozen seafood products, not from a Chinese lab as some have suggested. Sullivan expressed "deep respect" for the WHO -- which the US is rejoining after the Trump administration quit it to protest its virus response -- but said protecting its credibility is "a paramount priority." bbk/st
