Maybe its Sotomayor. She has become increasingly mentally unhinged thanks to Covid and now refuses to be in the same room as unmasked people, despite presumably being fully vaccinated. Since she's too afraid to attend in person work-related meetings, seems possible she's going to retire soon realizing that Covid is never going away.

I'm not sure what to make of this. All nine Justices are vaccinated and boosted, and Kavanaugh already had the virus.
Sotomayer has Type 1 diabetes which can dramatically increase risk even if vaccinated.
