Final answer:
The President of the United States appoints a Supreme Court Justice with the Senate's advice and consent.
Step-by-step explanation:
The appointment of a Supreme Court Justice is made by the President of the United States, with the advice and consent of the Senate.
Once a vacancy occurs, the President nominates an individual to serve as a Justice. The Senate then holds confirmation hearings to assess the qualifications of the nominee. If the Senate approves the nominee with a majority vote, the President officially appoints the Justice to the Supreme Court.
This process is outlined in Article II, Section 2 of the United States Constitution.
