It will be interesting to see who will be around to vote next week.
Cook is the one Trump is trying to fire and is a voting member. She just received a judgment to temporarily block that. So she will probably be around. Unless they can get another judge to remove that order.
Miran will be a voting member when confirmed. He had his hearing last week but as yet, no vote has been scheduled to confirm him. I'm sure a vote could be scheduled in plenty of time.
Some on the right did have some concern about Miran not leaving his job at the White House. His appointment is only until January, so I guess he doesn't want to leave his other job. Not sure why he isn't just taking a leave of absence.
There are extra members who are not currently voting. Not sure if they get rotated in if some of the voting seats are not filled.
