This is a classic slush fund, little more than a bribe to a Supreme Court Justice funneled through his spouse funneled to her through a dark money entity funneled to it by anonymous donors.

Activist group led by Ginni Thomas received nearly $600,000 in anonymous donations

Funding for the group led by Supreme Court Justice Clarence Thomas's wife was channeled through a right-wing think tank, an arrangement that effectively shielded key operational details from public view, a Post investigation found.

@maxkennerly It's easy to imagine a scenario where a payment to a spouse could have been legally defined as a payment to the official via indirect means and thereby illicit. We don't have that and it would seem to offend our notions of fairness (possibly even gender equity) but it's an open and obvious legal loophole. One can imagine another country with a functioning political system making this obvious tweek.

18 U.S.C ยง 208 is the general conflict of interest code, and it requires the executive branch (aka all federal agencies) to count spouse's financial interests. However the supreme court operates entirely outside of ethics or conflict of interest codes, which is the actual issue.
