Barron Trump tested positive for COVID-19 after his parents were infected but did not exhibit any symptoms, first lady Melania Trump revealed Wednesday.

“Naturally my mind went immediately to our son. To our great relief he tested negative, but again, as so many parents have thought over the past several months, I couldn’t help but think ‘what about tomorrow or the next day?’. My fear came true when he was tested again and it came up positive,” she wrote in a press release.
