Leonard Leo, the head of the Federalist Society, and the reason why the US Judiciary is full of half trained jackasses who put ideology ahead of the actual law. He worked with Bush and Trump to place Federalist Society judges throughout America. Especially the Supreme Court.
All three of Trump's picks were actually Leo's picks.
He also funds lawsuits against laws he doesn't like, and routes them through courts where he knows the judges, to appeals circuits where with judges he helped appoint, to the supreme court where 6 members owe him loyalty. (he also constantly bribes them)
Three of the cases heard by the court this last term were funded by Leo, including the gay wedding website case, where there was never a gay wedding. It was all made up. The "plaintiff" was actually a straight man, who was already married.
