Who is the current Chief Justice of the United States as of 2023?

The current Chief Justice of the United States as of 2023 is John Roberts. He was appointed to the position by President George W. Bush in 2005 and has been serving in this role since then. As Chief Justice, Roberts presides over Supreme Court sessions and ensures that court proceedings are conducted in an orderly manner. He also plays a significant role in deciding which cases the Supreme Court will hear and often shapes the court's overall direction, especially in his role as a key figure during deliberations.

Other individuals listed may hold significant positions within the Supreme Court, but they do not serve as the Chief Justice. For example, Clarence Thomas and Samuel Alito are both Associate Justices, and Ruth Bader Ginsburg, who served on the Supreme Court until her death in 2020, was also an Associate Justice. Therefore, while all these individuals have important roles, John Roberts is the one fulfilling the specific responsibilities and duties associated with being the Chief Justice.
