Article II, Section 2 of the U.S. Constitution provides that the President of the United States “shall nominate, and by and with the Advice and Consent of the Senate, shall appoint…officers of the United States.” Once a nomination is received by the Senate, the Senate’s executive clerk, acting on behalf of the Senate’s presiding officer, refers the nomination to the appropriate Committee or Committees on the day it is received. Once the Senate Commerce Committee receives a nomination referral, nominees are asked to supply additional information and meet with Committee members and staff. After completing the vetting, nominees may be asked to testify at one or more official nomination hearings, and a vote expressing a positive recommendation from the Senate Committee or Committees of jurisdiction is generally required before a full Senate vote.
