It WAS an accusation— made by DEMONRATS, who loved them some Gore. Speaking as one who among many took part in the FL “recount” the SCOTUS directed NOT to occur only in democrat counties.
So— this is not the reason for 2020. John Roberts is under threat by the obamaumao thugs of Islamofascism— both for the adoption of his children in Brazil, and possibly some hazy homo crap about him— which, in this day and age should not faze any SCOTUS justice much less the Chief Justice. The threat is coming from Deep State embeds from obamaumao- who are deeply afraid for what will and should happen to obama for what he has done to this country. A dish best eaten cold as it has been said.
However, if he did get his kids from Brazil, and from one specific individual, then they were probably trafficked.
There would be no statute of limitations on such an accusation.
