supreme court justices are appointed by

Supreme Court justices in the United States are appointed by the President and must be confirmed by the Senate. The President nominates a candidate when there is a vacancy, and then the Senate holds hearings and votes to confirm or reject the nominee. This process is established under Article II, Section 2, Clause 2 of the U.S. Constitution, often called the Appointments Clause. Once confirmed, justices serve lifetime terms until they die, retire, resign, or are removed through impeachment.
