Who has the power to appoint Supreme Court Justices?

The power to appoint Supreme Court Justices is vested in the President of the United States. This process is outlined in Article II, Section 2 of the U.S. Constitution, which states that the President shall nominate Supreme Court Justices, with the advice and consent of the Senate.

The role of the President in this process is crucial because it allows for the executive branch to influence the composition and ideological direction of the Supreme Court. Once the President nominates a candidate, the Senate holds hearings to evaluate the nominee and ultimately votes to confirm or reject the appointment.

This structure ensures a system of checks and balances, where the President's appointment power is balanced by the Senate's role in confirming or rejecting those nominations. The other options do not have authority in this process: the Senate participates in the confirmation but does not have the power to appoint, the House of Representatives does not play any role in the judicial appointments, and the Attorney General does not have appointment powers for the Supreme Court. Thus, the correct answer reflects the constitutional provision granting the appointment authority to the President.
