I was wondering the same thing, exit.
Some poor sap, on the main forum, had the nerve to ask that same question....only to get his/her head bashed in, with a supersnark reply :-(
The reply was that this gal won’t be seated until Breyer is officially gone.
🤷‍♀️
I hope that proviso is in writing in the actual resolution that the Senators voted on.
They never read anything anyway.
