President Trump sought to project an image of vigor in the face of COVID-19, with a surprise motorcade Sunday outside Walter Reed National Military Medical Center, where he is being treated, as his physicians suggested he could be discharged to return to the White House as early as Monday. The president was admitted to Walter Reed on Friday, hours after announcing that he and the first lady had tested positive for the coronavirus. On Sunday, the president — masked and waving from the back seat of a black SUV — was briefly driven past supporters gathered outside the compound after promising in a video "a little surprise to some of the great patriots that we have out on the street."
