A recently enacted federal statute requires the President to make each appointment of a United States ambassador to a foreign country from a list of three individuals. The list is to be compiled by the Senate Foreign Relations Committee and approved by the full Senate in advance of the appointment. The statute also provides that Senate confirmation of the appointment is deemed to occur automatically 30 days after the time the President names an appointee from the list, unless the full Senate determines otherwise within the 30-day period.
