Final answer:
Cabinet members are nominated by the President and confirmed by the Senate. They pledge to be responsive and accountable to Congress, although the confirmation process can be slow. It is rare for Cabinet members to be rejected by the Senate.
Step-by-step explanation:
Members of the Cabinet are appointed by the President and are confirmed or rejected by the Senate. Their principal role is to serve as advisors to the President and to execute policy in their respective departments. During the confirmation process, nominees often make commitments to be responsive and accountable to Congress.
Despite the prominence of Cabinet members, they, along with subcabinet officials and federal judges, can be subject to slow confirmation processes, and occasionally senators may block nominees to gain concessions or express discontent. In practice, Cabinet members are rarely rejected, as they generally receive approval from the Senate to support the President's governance team.
