Donald Trump has said China could have stopped the coronavirus before it swept the globe and said his administration was conducting 'serious investigations' into what happened. 'We believe it could have been stopped at the source. It could have been stopped quickly and it wouldn't have spread all over the world', Trump said at a White House news conference after a two-day pause on his daily coronavirus briefings. Trump also suggested that he would want to seek damages from China over their handling of the coronavirus outbreak.
