The president spent the first weekend in October at Walter Reed National Military Medical Center in Maryland receiving therapeutics. He finished his treatment and recovery at the White House.

A number of White House officials tested positive for coronavirus last month following a Rose Garden event in late September to formally nominate Judge Amy Coney Barrett to the Supreme Court. Those officials included White House press secretary Kayleigh McEnany, senior adviser Hope Hicks and director of Oval Office operations Nick Luna.

Other attendees of that event who tested positive included former counselor to the president Kellyanne Conway, former New Jersey Gov. Chris Christie, and Trump campaign manager Bill Stepien.

Meanwhile, in late October, Vice President Pence’s chief of staff Marc Short, and three other staffers tested positive for COVID-19. The vice president’s outside political adviser, Marty Obst, also tested positive.

As of Thursday, the U.S. has reported more than 10.4 million cases of COVID-19 and more than 240,000 deaths.
