One of the federal government’s top vaccine officials resigned from his role at the National Institutes of Health on Tuesday after accusing his superiors of politically motivated retaliation in response to his criticism of the Trump administration’s handling of the coronavirus pandemic.

Rick Bright, who formerly directed the Biomedical Advanced Research and Development Authority, was removed from his post in April and reassigned to a narrower role at NIH, where, he said in a whistleblower complaint, his work was “thwarted by political considerations that continue to harm public health and safety.” The complaint accuses Department of Health and Human Services leaders of giving Bright a less prestigious job because he pushed back against President Trump’s lofty claims about hydroxychloroquine’s potential as a covid-19 treatment.

Here are some significant developments:

  • Stephen Miller, Trump’s senior policy adviser, tested positive for the novel coronavirus, the latest in a string of White House officials to be infected.
  • The White House on Tuesday approved tough new standards for coronavirus vaccines after weeks of delay, but only after the Food and Drug Administration unilaterally published the guidelines on its website.
  • Trump said Tuesday that the coronavirus relief talks were over until after the election, abruptly ordering Treasury Secretary Steven Mnuchin to stop negotiating with House Speaker Nancy Pelosi.
  • The stock market plummeted in the last hour of Tuesday’s trading, as investors reacted to Trump’s announcement.
  • Members of the Joint Chiefs of Staff are in isolation after the Coast Guard’s No. 2 officer tested positive for the coronavirus, the Pentagon said Tuesday in a statement.
  • Vice President Pence requested that no plexiglass dividers be placed on his side of the stage at Wednesday night’s vice-presidential debate, but the Commission on Presidential Debates built a stage Tuesday with barriers for both candidates, apparently overruling his objections.
  • At least 210,000 people in the United States have died of the coronavirus, according to data tracked by The Washington Post, while more than 7.4 million cases have been reported.
