The November presidential election -- less than one month away -- was thrown into uncertainty last week, when President Trump announced that he and the first lady tested positive for the novel coronavirus.

Trump's COVID-19 diagnosis prompted the White House to cancel previously scheduled campaign events, temporarily sidelining the president as his re-election campaign enters the final stretch of the race against Democratic rival Joe Biden.

I know there’s a risk, there’s a danger, but that’s OK."
