Fox News star Tucker Carlson, all but alone among his fellow Fox primetime hosts in framing the novel coronavirus pandemic as a serious problem instead of a partisan hoax to hurt President Donald Trump, is potentially coping with his own concerns regarding his potential exposure to COVID-19.

Carlson was among several guests at Mar-a-Lago last weekend who shook hands with Brazilian President Jair Bolsonaro in close proximity to his press secretary, who has tested positive for the disease. Trump stood close by as Carlson greeted Bolsonaro. Since that Saturday night encounter, several conservative lawmakers and the mayor of Miami, who was also present, have self-quarantined.
