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.
Monday's headlines:

Trump received oxygen treatment twice
Dr. Conley, when questioned, told reporters that Trump had two episodes that required he receive oxygen treatment and "recovered immediately."
On Sunday Conley would only confirm there was one time where Trump needed oxygen but said he would need to check with the nurses assisting with the president's treatment.
"He wasn't short of breath, he wasn't looking ill. It was more of us trying to anticipate needs and see how he’d respond, and both cases he came right off. He didn't need it for very long at all," Conley said.
Dr. Conley was asked and refused to comment on President Trump's tweet telling people "Don't be afraid of Covid."
"I'm not going to get into what the president says," Conley told reporters.
'In a bit of uncharted territory' with Trump treatment
Dr. Conley, the president's physician, was asked about concerns of Trump's symptoms becoming worse after he is discharged and said the team remains "cautiously optimistic" and "on guard."
"We are in a bit of uncharted territory when it comes to a patient that received therapies he has so early in the course," he said. "If we can get through to Monday with him remaining the same or improving, better yet, then we will all take that final deep sigh of relief."
Trump departing Walter Reed for White House
After spending three nights in the hospital, Trump is departing Walter Reed Military Medical Center in Bethesda, Maryland, en route to the White House, despite not having completed his full COVID-19 treatment.
Trump -- in a mask -- surrounded by Secret Service -- walked out of the hospital at 6:38 p.m. ET and waved to reporters as he entered a vehicle to take him to Marine One.
He did not answer shouted questions from the press on the health of his staff.
The president tweeted shortly before his departure that he "Will be back on the Campaign Trail soon!!!"
Earlier in the day, the president’s physician said he supported Trump's move to the White House but also acknowledged the president is “not necessarily out of the woods yet” and that he is on “uncharted territory” in terms of his treatment.
Guidelines from the Center for Disease Control and Prevention say that transporting a patient “outside of their room should be limited to medically essential purposes.”
Trump arrived on Friday evening after announcing at 12:54 a.m. on Twitter that he had tested positive for COVID-19.
