Who is justice 2? (Justice 1 would be Roberts). Thomas is second in seniority, I think.
Thomas would be #2 in seniority.
And since Roberts should also recuse, being head of the corrupted FISC and already recused + friend of Strzok, Judge Rudy Contreras, that means that Roberts is in check.
I presume that RBG already knows what her fate is ... tick tock ;)
