President Donald Trump

Referring to a report that the FDA plans to tighten requirements for a vaccine, Trump said, "That sounds like a political move."

In a speech to the U.N. General Assembly, the president once again sought to blame China for the COVID-19 pandemic and called on Beijing to be punished for its handling of the disease.

The president has contradicted health experts, and now his own ambitious timeline, for a vaccine against COVID-19.

The order, which would include Medicare parts B and D, replaces a previous order the president signed in July, but the move is unlikely to have any immediate practical impact.

"I don't want to jump up and down and start screaming, 'Death! Death!' " the president said when asked about why he publicly downplayed the pandemic while privately acknowledging its severity.

President Trump says he didn't want to create panic when pressed on revelations about what he knew early on about the threat of the pandemic versus what he stated publicly.

Dr. Scott Atlas is a radiologist from Stanford with some unorthodox ideas about managing the pandemic. The White House says his thinking is just what's needed, but scientists aren't so sure.

A Trump administration spokesman says Washington will continue to engage the rest of the world in vaccine development but won't be "constrained" by the "corrupt" World Health Organization.

NPR's Ari Shapiro talks with Health and Human Services Secretary Alex Azar about the Food and Drug Administration allowing the use of convalescent plasma to treat COVID-19.

President Trump announced on Sunday that the FDA granted emergency use authorization to treat COVID-19 patients with plasma from people who have recovered from the virus, based on "promising" results.
