My mother’s friend called up. I have no idea where she heard this, she does not use the internet. Anyways she told my mother Ivanka,her husband and their kids cannot live in the White House because there is a rule adult children cannot live in White House.

I have found nothing on this. I would think since President Obama can allow his MIL to live with them President Trump can have his whole clan living there. The question is just space and practicality. I would bet only Melania and his young son will live at the White House, I see no reason why Trump would have his adult children living there. Although I cannot fathom why he could not.

It seems more like a myth or more likely she misheard and came to this conclusion.

Is there such a prohibition on adult children.
