BETHESDA, Md. (NEXSTAR) — President Donald Trump will be discharged Monday from Walter Reed National Military Medical Center as he continues to battle the novel coronavirus, according to a tweet he sent Monday afternoon.

“I will be leaving the great Walter Reed Medical Center today at 6:30 P.M. Feeling really good! Don’t be afraid of Covid. Don’t let it dominate your life,” Trumped tweeted. “We have developed, under the Trump Administration, some really great drugs & knowledge. I feel better than I did 20 years ago.”

Doctors report Trump’s condition continues to improve and plan to update reporters on his condition Monday afternoon. After spending three days hospitalized, the president will continue to receive care at the White House.

Even with this positive development, health concerns remain for the president.

On Sunday morning, Trump’s medical team reported that his blood oxygen level dropped suddenly twice in recent days and that they gave him a steroid typically only recommended for the very sick.

Over the weekend, a number of contradictions from doctors and the White House fueled confusion about Trump’s health. While Trump’s physician offered a rosy prognosis on his condition, his briefings lacked basic information, including the findings of lung scans, or were quickly muddled by more serious assessments of the president’s health by other officials.

In a short video released by the White House on Sunday, Trump insisted he understood the gravity of the moment. But his actions moments later, leaving the hospital and driving in an SUV with others to greet his supporters, was criticized by many who said his actions contradicted his statement.

“This is insanity,” Dr. James P. Phillips, an attending physician at Walter Reed who is a critic of Trump and his handling of the pandemic. “Every single person in the vehicle during that completely unnecessary presidential ‘drive-by’ just now has to be quarantined for 14 days. They might get sick. They may die.”

“For political theater,” the doctor added. “Commanded by Trump to put their lives at risk for theater.”

White House spokesman Judd Deere said Trump’s trip outside the hospital “was cleared by the medical team as safe to do.” He added that precautions were taken, including using personal protective equipment, to protect Trump as well as White House officials and Secret Service agents.

As the president prepares to leave Walter Reed, questions remain about his health.

His doctors sidestepped questions on Sunday about exactly when Trump’s blood oxygen dropped — an episode they neglected to mention in multiple statements the day before — or whether lung scans showed any damage.

It was the second straight day of obfuscation from a White House already suffering from a credibility crisis. And it raised more doubts about whether the doctors treating the president were sharing accurate, timely information with the American public about the severity of his condition.

Pressed about conflicting information he and the White House released on Saturday, Navy Cmdr. Dr. Sean Conley acknowledged that he had tried to present a sunnier description of the president’s condition.

“I was trying to reflect the upbeat attitude that the team, the president, that his course of illness has had. Didn’t want to give any information that might steer the course of illness in another direction,” Conley said. “And in doing so, you know, it came off that we were trying to hide something, which wasn’t necessarily true. The fact of the matter is that he’s doing really well.”

Medical experts said Conley’s revelations were hard to square with his positive assessment and talk of a discharge.

“There’s a little bit of a disconnect,” said Dr. Steven Shapiro, chief medical and scientific officer at the University of Pittsburgh Medical Center.

The disclosures about Trump’s oxygen levels and steroid treatment suggested the president is enduring more than a mild case of COVID-19.

Blood oxygen saturation is a key health marker for COVID-19 patients. A normal reading is between 95 and 100. Conley said the president had a “high fever” and a blood oxygen level below 94% on Friday and during “another episode” on Saturday.

He was evasive about the timing of Trump oxygen drops. (“It was over the course of the day, yeah, yesterday morning,” he said) and asked whether Trump’s level had dropped below 90%, into concerning territory. (“We don’t have any recordings here on that.”) But he revealed that Trump was given a dose of the steroid dexamethasone in response.

At the time of the briefing, Trump’s blood oxygen level was 98% — within normal rage, Trump’s medical team said.

Signs of pneumonia or other lung damage could be detected in scans before a patient feels short of breath, but the president’s doctors declined to say what those scans have revealed.

“There’s some expected findings, but nothing of any major clinical concern,” Conley said. He declined to outline those “expected findings.”

In all, nearly 7.4 million people have been infected in the United States, and few have access to the kind of around-the-clock attention and experimental treatments as Trump.

Trump’s treatment with the steroid dexamethasone is in addition to the single dose he was given Friday of an experimental drug from Regeneron Pharmaceuticals Inc. that supplies antibodies to help the immune system fight the virus. Trump on Friday also began a five-day course of remdesivir, a Gilead Sciences drug currently used for moderately and severely ill patients. The drugs work in different ways — the antibodies help the immune system rid the body of virus, and remdesivir curbs the virus’ ability to multiply.

Garibaldi, a specialist in pulmonary critical care, said the president was not showing any side effects of the drugs “that we can tell.”

The National Institutes of Health COVID-19 treatment guidelines recommend against using dexamethasone in patients who do not require oxygen. It has only been proven to help in more serious cases. Among the concerns with earlier use is that steroids tamp down certain immune cells, hindering the body’s own ability to fight off infection.

Trump is 74 years old and clinically obese, putting him at higher risk of serious complications.

First lady Melania Trump has remained at the White House as she recovers from her own bout with the virus.
