President Joe Biden plans to end two national emergency declarations over the COVID-19 pandemic on May 11, which will trigger a restructuring of the federal response to the deadly coronavirus and will end most federal support for COVID-19 vaccinations, testing, and hospital care.

The plan was revealed in a statement to Congress opposing House Republicans’ efforts to end the emergency declarations immediately.

“An abrupt end to the emergency declarations would create wide-ranging chaos and uncertainty throughout the health care system—for states, for hospitals and doctors’ offices, and, most importantly, for tens of millions of Americans,” the Office of Management and Budget wrote in a Statement of Administration Policy.
