Trump, who is now being treated for the coronavirus, received the result before making an appearance on Fox News, The Wall Street Journal reported.
“I’ll get my test back either tonight or tomorrow morning,” Mr. Trump said during the interview. At 1 am on Friday.
“Don’t tell anyone,” Trump told an adviser about disclosing the results of their own positive test.
"The initial secrecy within Mr. Trump’s inner circle has created a sense of anxiety within the West Wing. Publicly, the White House has issued evolving and contradictory statements about the president’s health that has some officials worried about their own credibility," read the report.
Trump left his hospital suite on Sunday to greet his supporters outside Walter Reed National Military Medical Center from his motorcade.
"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," deputy White House press secretary Judd Deere said in a statement.
