I hadn’t thought about Melania’s parents - good thought. I did think about Barron - he likes to work on the computer. Given his age, I suspect he may play some games online, like my nephew does (Xbox live and possibly another one or 2) and he chats with kids all over the country while he’s playing the games with them.
He also speaks his grandparents language. So it is a possible clause that they translated and unmasked a conversation between Barron and his grandparents. Scumbags!
