Since it was revealed that White House adviser Hope Hicks had tested positive for COVID-19, more than a dozen other cases in Washington, D.C., have come to light -- including that of President Donald Trump.
Here's a look at prominent political players ABC News has confirmed have tested positive or negative for the virus since Hicks' case so far. Among the positive cases are several attendees of key events at the White House this past week: the SCOTUS nomination last Saturday and a prep session on Monday ahead of the first presidential debate. Several were also at the debate itself on Tuesday in Cleveland.
