Whistleblower Testifies on 'Scientific Integrity' in US Coronavirus Response Katherine Gypson The United States lacks a comprehensive plan to respond to the coronavirus, a U.S. health official warned lawmakers Thursday. Dr. Rick Bright, an immunologist for the Department of Health and Human Services (HHS), issued the warning in testimony before a congressional committee. He alleged in a whistleblower complaint that he was removed from his position for prioritizing science in the government's coronavirus response. Bright told a House panel that time was running out for the United States to mount a response to the pandemic, and he warned that a resurgence of the virus in the fall could result in 2020 becoming "the darkest winter in modern history." As of Thursday afternoon EDT, the pandemic had killed more than 85,000 people in the United States, according to figures from Johns Hopkins University. President Donald Trump criticized Bright ahead of his testimony, tweeting Thursday morning, "He is a disgruntled employee, not liked or respected by people I spoke to and who, with his attitude, should no longer be working for our government!" Until last month, Bright was the director of the Biomedical Advanced Research and Development Authority (BARDA), a U.S. agency responsible for vaccine development. 'Politicizing the response' In a statement, HHS said Bright was continuing to draw a salary "while using his taxpayer-funded medical leave to work with partisan attorneys who are politicizing the response to COVID-19." But House Democrats said Bright's concerns provided a critical picture of the U.S. government's response to the pandemic. .
