In addition to the steroids, Mr. Trump has received an experimental antibody cocktail and is in the midst of a five-day course of remdesivir, an antiviral drug. The White House has a medical unit capable of responding to a president’s health troubles but not with the sophisticated equipment available at Walter Reed.
Mr. Trump, who historically hates hospitals and anything related to illness, has been hankering to get released, according to two people close to him, and some aides expressed fear that he would pressure Dr. Conley into releasing him by claiming to feel better than he actually does. But advisers were also troubled by the doctors’ prediction that they might release him on Monday because if they do not, it would signal that the president is not doing as well as indicated. They also worried that a premature return could lead to a second trip to the hospital if his condition worsens.
Mr. Trump was said to be working from his hospital suite, including receiving a briefing via secure video conference from Robert C. O’Brien, his national security adviser, as well as Secretary of State Mike Pompeo and Gen. Mark A. Milley, the chairman of the Joint Chiefs of Staff.
The president has also been watching lots of television, even more than usual, and has been exasperated by coverage of Saturday’s calamitous handling of his medical information by Dr. Conley and Mr. Meadows, as well as speculation about him transferring powers to Vice President Mike Pence.
He was also angry that no one was on television defending him, as he often is when he cannot inject his own views into news media coverage, aides said. As a result, Rudolph W. Giuliani, his personal lawyer, was expected to appear on several television shows, as was Corey Lewandowski, who was Mr. Trump’s first campaign manager in the 2016 race.
The president was not the only one angry over the weekend. So were many people who work for him at the White House, frustrated at how little information they had received about the health concerns in their workplace. In addition to Mr. Trump, a number of others who work or visit the building regularly have tested positive, including Melania Trump; Hope Hicks, a senior adviser to the president; Nicholas Luna, the director of Oval Office operations; Bill Stepien, the campaign manager; Ronna McDaniel, the chairwoman of the Republican National Committee; and Kellyanne Conway, the president’s former counselor.
Two members of the White House residence staff tested positive for the virus a few weeks ago, two people briefed on their cases said, although they were said not to come in close contact with the president or the first lady. Nonetheless, the presence of the virus in the first couple’s personal quarters once again raised questions not just about what they have been exposed to, but whom they have made vulnerable with lax mask policies around the White House.
