President arrives at White House, removes mask and salutes
In a tweet announcing the move, Trump wrote, "Don't be afraid of Covid."
President Donald Trump's condition is continuing to improve as he fights a coronavirus infection, doctors said, and he left Walter Reed Medical Center on Monday evening, landing at the White House shortly before 7 p.m.
Doctors also reported that Trump, over the course of exhibiting coronavirus symptoms, had earlier experienced two episodes of "transient drops" in his oxygen saturation.
Yet the president was feeling well enough Sunday evening to briefly leave Walter Reed for a surprise drive-by, waving to supporters outside the hospital.
Administration member Judd Deere subsequently put out a statement saying that, "President Trump took a short, last-minute motorcade ride to wave to his supporters outside and has now returned to the Presidential Suite inside Walter Reed."
Meanwhile, numerous questions remain about how many people at the highest levels of government had been exposed to the virus after a week of events involving the president where social distancing and mask-wearing were lax in the White House and elsewhere.

White House urges staff to keep distance if sick days after positive cases
Staff at the White House were urged to stay home if they were sick days after President Trump and some of his advisers tested positive for the coronavirus, according to an email sent to the staff and obtained by ABC News.
One of Trump's closest advisers Hope Hicks was the first White House official to test positive on Wednesday, sources told ABC News. On Tuesday, she had traveled with the president on Air Force One to and from the debate and was seen in social media posts watching the debate in a "war room."
Trump and first lady Melania Trump announced they had tested positive for the coronavirus early Friday morning.
In addition to Hicks and the president, three other participants in debate preparations at the White House last Monday have tested positive: Campaign manager Bill Stepien, former adviser Kellyanne Conway and former New Jersey governor and ABC contributor Chris Christie.
The email to White House staff urges them to stay home if "you are experiencing symptoms such as sore throat, cough, fever, headache, new loss of taste or smell, muscle aches, chills, diarrhea, or difficulty breathing."
