Understanding these records
PN means presidential nomination. Each numbered record tracks a proposal sent to the Senate.
A Senate confirmation approves a nomination; it is not proof of current tenure or an appointment taking effect. These entries show received dates and the latest recorded action, rather than a complete legislative action timeline.
