[Update: President Trump has tweeted that he and First Lady Melania Trump tested positive for the coronavirus.]
President Trump said late Thursday on Twitter that he and the first lady, Melania Trump, would begin the “quarantine process” as they await results of coronavirus tests they took after a senior adviser who is often with the couple tested positive.
It was not immediately clear what Mr. Trump meant by the “quarantine process,” and White House officials declined to immediately provide any guidance. As of 11:30 p.m., the president still had a full day of events planned for Friday, including a private fund-raiser at the Trump International Hotel in Washington and a campaign rally in Florida. He was also scheduled to hold a call with “vulnerable seniors” about the coronavirus.
And even if Mr. Trump first tests negative for the virus, the incubation period for it can last nearly two weeks,
