Trump announces plasma treatment authorized for COVID-19

President Donald Trump announced emergency authorization to treat COVID-19 patients with convalescent plasma — a move he called “a breakthrough,” one of his top health officials called “promising” and other health experts said needs more study before it’s celebrated. The announcement Sunday came after White House officials complained there were politically motivated delays by the Food and Drug Administration in approving a vaccine and therapeutics for the disease that has upended Trump’s reelection chances. On the eve of the Republican National Convention, Trump put himself at the center of the FDA’s announcement of the authorization at a news conference Sunday evening.
