LoL!
I'm supposed to Wade through those websites looking for support for your claim? Nah I don't think so.
If you had seen anything in either of those two links that supports your claim, you would have gleefully copied and pasted it. You really need to reread that propublica article.
It would have been more honest of you to just post a link to that propublica article. That's the source of your so-called information. You never looked at those two websites until I just asked the question. You saw something negative about a black Republican so you ran with it. End of story.
The gist of it on careful reading is that if the rules that exist today had existed back then Justice Thomas would have been guilty of failing to report something he was required to report.
"If."
We don't have Ex post facto laws in this country, thanks to justices like Clarence Thomas who believe that the constitution means what it says it means.
Stop hating on Justice Thomas just because he is a black republican.
