The facts are the Roberts’ adopted 2 children from Ireland, a country that does not allow adoption of its children by noncitizens. It was done by having the mothers go to a South American country with their infants and the adoption took place there.
The assumption is that that was an illegal way to adopt these children.
Don’t blast me for this - I’m just relaying the information. I personally think it’s more likely that Roberts was looking at ‘his’ court’s legacy and thought it needed to appear bipartisan or nonpartisan, actually.
It was explained in full, further into the thread.
