Yes, the institution that should have the tightest ethical code has virtually no ethical code. We've got Supremes who live the high life
and think they're above the law. Chief Justice Roberts has been a failure as the court's leader as he could probably reign in Thomas and others but apparently chooses to do little even as the Justices have complained about the criticism they've received in recent years--all of it well deserved. Roberts recently refused to go along with a Congressional effort to get SCOTUS to adopt a more serious ethical code.
Forget disclosure: SCOTUS justices should not be accepting ANY gifts, trips or favors from anybody--period. As for Thomas, he's always been a lightweight and a grifter--a total embarrassment. Alito was another unethical conservative justice--went on scores of trips and actually died had a swanky hunting lodge somewhere. The court has lost its way over the last decade as it has become increasingly politicized. And let's add that Citizens United was a disgraceful decision that has done serious damage to the country.
