This admin, for whatever reasons, is months behind the normal schedual.

Please describe your process for properly vetting, nominating, debating, and confirming all (or most) ambassadorships in 4+ days, since you see that as "normal practice". Extra credit: name any three administrations that have done so.

I would hope that the Secretary of State would have some say in ambassadorships, in which case the process would also be constrained until the SecState nominee is confirmed.
