The Constitution authorizes the president of the United States to appoint individuals to executive and judicial offices with the advice and consent of the Senate.
This all-important check upon the president’s power gives the Senate influence over the composition of the executive and judicial branches. Although the Senate has confirmed the vast majority of presidential nominations, its consideration of nominees has produced some notable confrontations between the legislature and the chief executive. This advice-and-consent role is one of the most significant constitutional checks on the presidency.
