Still infectious Trump back at White House without mask

US President Donald Trump staged a dramatic return to the White House Monday night after leaving the military hospital where he was receiving an unprecedented level of care for COVID-19. He immediately ignited a new controversy by declaring that despite his illness the nation should not fear the virus that has killed more than 210,000 Americans — and then he entered the White House without a protective mask.

Trump’s message alarmed infectious disease experts and suggested the president’s own illness had not caused him to rethink his often-cavalier attitude toward the disease, which has also infected the first lady and several White House aides, including new cases revealed on Monday.
