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.
Sen. Lindsey Graham, R-S.C., said he spoke with President Trump on Monday morning, saying he "sounds terrific," "very engaged" and is "ready to get back to work."
Graham, who is the chairman of the Senate Judiciary Committee overseeing the nomination of Judge Amy Coney Barrett to the Supreme Court, said Trump is excited about Barrett being confirmed to the high court.
White House press secretary Kayleigh McEnany tweeted on Monday that she has tested positive for the coronavirus.
McEnany said she had consistently tested negative every day since Thursday, but the positive result came back on Monday morning.
She said she is not experiencing any COVID-19 symptoms and will begin the quarantine process.
First lady Melania Trump said she is "feeling good & will continue to rest at home" in a tweet she posted Monday morning.
President Trump announced early Friday morning that he and Melania Trump had both tested positive for the coronavirus.
Melania Trump has stayed at the White House since her positive test, while President Trump has been at Walter Reed Medical Center since Friday afternoon. Doctors are hopeful the president will be discharged later Monday.
Vice President Mike Pence and second lady Karen Pence both tested negative for the coronavirus on Monday, according to an official in the vice president's office.
"Both the vice president and second lady are negative again today," the official said.
