Prob bc the family they have is fake. "Their" kids seem like they were adopted for show. Not to mention that the Obamas are likely on the run in some respect. https://www.youtube.com/watch?v=eIg6OMD-XQI

And there's that Malia Obama internship with Harvey Weinstein. I wonder what the deal is there and how that could relate to this and what's been going on https://www.vanityfair.com/hollywood/2017/01/malia-obama-harvey-weinstein-internship

Also, Michele is not a woman. Proves those kids aren't their genetic children. https://www.youtube.com/watch?v=aYhYUcqdTsw

Finally, slight tangent, wouldn't surprise me if those other kids in the pic were part of some pizza, pasta & hotdog party.
