Section 2 also requires the "principal officer" of any executive department to tender advice. Though not required by Article Two, President George Washington organized the principal officers of the executive departments into the Cabinet, a practice that subsequent presidents have followed. The Treaty Clause grants the president the power to enter into treaties with the approval of two-thirds of the Senate. The Appointments Clause grants the president the power to appoint judges and public officials subject to the advice and consent of the Senate, which in practice has meant that presidential appointees must be confirmed by a majority vote in the Senate. The Appointments Clause also establishes that Congress can, by law, allow the president, the courts, or the heads of departments to appoint "inferior officers" without requiring the advice and consent of the Senate. The final clause of Section 2 grants the president the power to make recess appointments to fill vacancies that occur when the Senate is in recess.
