As President Trump prepared to return to the White House on Monday after a four-day stay at the hospital, his Democratic rival, Joseph R. Biden Jr., campaigned in Florida, where he expressed hope that the president was recovering but urged Americans not to minimize the threat posed by the coronavirus.
“I hope the president’s recovery is swift and successful, but the nation’s Covid crisis is far, far from over,” Mr. Biden said at a gym in Miami’s Little Havana, where people in a small, socially-distanced crowd were seated at least six feet apart from one another and wore masks.
Mr. Biden once again urged Mr. Trump — who has sent lukewarm-to-mixed signals on the importance of wearing masks, and who had mocked the vice president at the debate just last week for wearing masks — to embrace universal masking, saying it would save lives.
“Since the president was in the hospital, since Friday, more than 100,000 more people have been diagnosed with Covid,” Mr. Biden said, according to a pool report. “Cases and deaths are climbing in many states.”
The president’s hospitalization after testing positive for the coronavirus — and the virus’s spread through his administration and orbit — brought the pandemic back to the center of the presidential campaign.
Earlier, as he prepared to leave Delaware on Monday morning, Mr. Biden had declined to weigh in on Mr. Trump’s decision to briefly leave Walter Reed National Military Medical Center on Sunday evening to drive past his supporters, an excursion that may have endangered members of his security detail and that runs counter to health guidelines, which call for sick
