President Donald Trump's physician, Navy Cmdr. Dr. Sean Conley, said Sunday morning that the President has had at least two concerning drops in oxygen levels, but is doing well and he is hoping Trump could be discharged as early as tomorrow from Walter Reed National Military Medical Center.

Some seven months into a pandemic that has killed more than 209,000 Americans, the nation is now facing a grave governing crisis with its commander in chief hospitalized -- his condition hinging on his progress over the coming days -- as the White House events of the past week serve as a textbook example of how not to handle a deadly virus.

Late Saturday night, the public learned new details about why Trump was airlifted to the hospital Friday, when chief of staff Mark Meadows said during an interview with Fox News that Trump had a fever on Friday morning and his oxygen level had "dropped rapidly." Meadows added that Trump has made "unbelievable improvements from yesterday morning."

A memo from Trump's physician earlier Saturday night said that Trump had "made substantial progress" since his diagnosis but "is not yet out of the woods."

Speaking from a White House that already has a huge credibility problem with the public, Meadows' statement capped a 24-hour period that served as a master class in opacity and contradiction that raised major questions about the President's health -- and renewed questions about this administration's ability to tell the truth.

Trump has been watching and critiquing coverage of his hospitalization from the presidential suite at Walter Reed and has been agitated at what he claims are exaggerated descriptions of his condition, people familiar with the matter said.
