WASHINGTON — President Joe Biden informed Congress on Monday that he will end the twin national emergencies for addressing COVID-19 on May 11, as most of the world has returned closer to normalcy nearly three years after they were first declared.

The move to end the national emergency and public health emergency declarations would formally restructure the federal coronavirus response to treat the virus as an endemic threat to public health that can be managed through agencies’ normal authorities.

It comes as lawmakers have already ended elements of the emergencies that kept millions of Americans insured during the pandemic. Combined with the drawdown of most federal COVID-19 relief money, it would also shift the development of vaccines and treatments away from the direct management of the federal government.

Biden’s announcement comes in a statement opposing resolutions being brought to the floor this week by House Republicans to bring the emergency to an immediate end. House Republicans are also gearing up to launch investigations on the federal government’s response to COVID-19.

Then-President Donald Trump first declared the COVID-19 pandemic a national emergency on March 13, 2020. The emergencies have been repeatedly extended by Biden since he took office in January 2021, and are set to expire in the coming months. The White House said Biden plans to extend them both briefly to end on May 11.

“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.
