The presidential campaign was upended last week, a little more than a month before the November election, when President Trump tweeted that he and the first lady tested positive for the novel coronavirus.

Trump's COVID-19 diagnosis, which came hours after his longtime aide Hope Hicks had fallen ill with the virus, prompted the White House to cancel previously scheduled campaign events.
