Who appoints US Supreme Court justices?

The appointment of US Supreme Court justices is the responsibility of the President. This process is outlined in the U.S. Constitution, specifically in Article II, Section 2. The President selects nominees for the Supreme Court, drawing from various sources, including recommendations from legal advisors, senators, and other political allies. These nominations reflect the President's judicial philosophy and policy preferences, as the justices hold significant power in interpreting laws and the Constitution.

Once the President has made a nomination, the Senate plays a critical role in the confirmation process. Senators conduct hearings, debate the nominee’s qualifications, and ultimately vote to confirm or reject the nominee. However, the initial appointment lies solely with the President, making this choice the correct answer.
