There were no kids in the US he could adopt??
Adoption in the US is full of legalistic entanglements and is filled with White Privilege restrictions and so forth such as if you’re White Caucasian Christian you must adopt the black African Somalian kid and respect the child’s Muslim heritage, etc. It’s a politically correct nightmare by design.
