Dunno what WBD and Melania had, but in Malaysia the prime minister and his second wife did this:
“Fazley Yaakob, the husband of Mr. Najib’s stepdaughter, offered another story, which he recounted on Instagram after Mr. Najib lost the election. Before the two were married, Mr. Fazley wrote, Ms. Rosmah hired a witch doctor to assess the suitability of the union. The witch doctor warned against the marriage because Mr. Fazley, unlike others, would be able to resist Ms. Rosmah’s supernatural powers.”
We haven’t had a first lady like that since Nancy Reagan.
