President Trump says he will be leaving the hospital Monday evening

President Donald Trump tweeted Monday afternoon that he would be leaving Walter Reed Medical Center at 6:30 p.m. ET.

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

Trump's announcement came hours after White House Chief of Staff Mark Meadows said in an appearance on Fox News that Trump's condition has continued to improve, and that officials will meet with Trump's doctors to determine if the president can be discharged from the hospital this afternoon.

"Obviously, he continued to improve overnight. His health continues to improve," Meadows said during an appearance on Fox & Friends Monday morning. "The doctors will have an evaluation sometime late morning, and then president, in consultation with doctors, will make a decision on whether to discharge him later today."

"Though he may not entirely be out of the woods yet, the team and I agree that all our evaluations, and more importantly, his clinical status, support the president's safe return home, where he'll be surrounded by world-class medical care, 24/7," Dr. Sean Conley, the White House physician, told reporters outside the facility on Monday afternoon, according to CBS News.

Trump has been hospitalized with COVID-19 at Walter Reed Medical Center since Friday. While Trump's doctors have painted an encouraging picture of his condition since he's arrived at the hospital, there are other signs that he is suffering from more than a mild case of the virus.

On Saturday, Trump's doctors painted a mostly optimistic outlook on his condition, saying that he was making tremendous progress and continuing to work despite the diagnosis. However, they declined to say whether Trump had received supplemental oxygen since he began experiencing symptoms and how high his fever reached. It's since been confirmed that Trump did briefly receive supplemental oxygen since contracting the virus.

Following that Saturday press conference, a White House official told pool reporters on background that Trump's vitals over the last 24 hours had been "very concerning" and that the next 48 hours were "critical" in his recovery.

On Sunday, Trump's doctors gave more information on the cocktail of drugs the president was taking to fight the virus. Those medications included dexamethasone — a steroid that the AP and other outlets reported is usually given to "critically ill" patients.

Later on Sunday, Trump briefly left Walter Reed in a car driven by Secret Service agents to wave to a group of his supporters that were camped outside the hospital.
