A week ago, more than 100 people gathered in the White House Rose Garden to celebrate President Trump's third nominee to the U.S. Supreme Court, Amy Coney Barrett. Guests mingled, hugged and kissed on the cheek, most without wearing masks. An indoor reception followed the outdoor ceremony. Seven days later, at least eight people who attended the ceremony have tested positive for the coronavirus, including the president. Several more of the president's closest aides and advisers have also tested positive.
