President Donald Trump waved to supporters outside Walter Reed National Military Medical Center before returning to his presidential suite. He also said he "learned a lot about Covid" during his stay.

Earlier, a press briefing led by White House physician Dr. Sean Conley led to more questions than answers about Trump's health.

Conley said Trump's condition has improved and he could be discharged from as early as Monday. Yet he also revealed the president's oxygen saturation levels dropped below 95% twice, once on Friday and once on Saturday. The president was also given supplemental oxygen at least once and he has been treated with a steroid that is normally only used in severe cases of Covid-19. 

Health experts are concerned the president's condition is more serious than originally thought, and doubt that a release on Monday is realistic. 

Here are today's major developments so far:
