A whistleblower in the US who says he was removed from his government post for raising concerns about coronavirus preparedness, on Thursday told a congressional hearing that the United States could face what he described as the darkest winter of recent times if it does not improve its response to the pandemic.
Hours after President Donald Trump railed against him on Twitter, whistleblower Rick Bright testified to a U.S. House of Representatives panel about readiness for the outbreak.
Mr. Bright was removed last month as director of the Biomedical Advanced Research and Development Authority, or BARDA, which is responsible for developing drugs to fight the coronavirus.
He said the country's window of opportunity is closing.
Mr. Bright warned that if the US fails to improve its response, based on science, the pandemic will get worse and be prolonged.
