US President Donald Trump returned to his daily briefings to attack China over its handling of the coronavirus.
Trump said China could have stopped the virus before it spread across the world and that his administration was investigating what happened.
"We're doing very serious investigations. .. We are not happy with China," Trump told the White House media conference. "There are a lot of ways you can hold them accountable. We believe it could have been stopped at source. It could have been stopped quickly and wouldn't have spread all over the world."
