President Joe Biden speaks during a meeting with the President’s Council of Advisors on Science and Technology in the State Dining Room of the White House on April 4, in Washington, D.C. The U.S. national emergency to respond to the COVID-19 pandemic ended April 10, as Biden signed a bipartisan congressional resolution to bring it to a close after three years — weeks before it was set to expire alongside a separate public health emergency.
