I would recuse myself, but I also assume the powers at be would make sure I wasnt the one presiding over the case. I dont know if that is possible with the SC though, since they are highest legal entity. Roberts might have some authority to force people to recuse themselves, I honestly dont know, but ultimately the person directly involved should have the professionalism to recuse themselves. I honestly think, if we werent in such partisan times, that this would be a major controversy that historians would be writing about years from now.
But also to be clear, she wasnt accused of a crime in the 1/6 ruling. It was just about whether Trump had to turn over certain documents or not, but really had nothing to do with her specifically. The question, especially with what we know now, is why did Thomas rule the way he did? He was the only one to dissent, which at least raises some serious questions, because it is possible he knows his wife will be a part of some of those documents. If that is the case, he needs to resign, and we certainly need to find out if that was the case or not.
If you have read her texts, she was essentially trying to make sure Trump's people knew if this went to the SC, they would win. Obviously, we dont know that for sure, but considering her husband would be one of the people ruling on it, I think it is pretty disturbing for her to even be pushing that idea to Trump's inner circle.
