Who is currently the Chief Justice of the United States Supreme Court?

The Chief Justice of the United States Supreme Court is John Roberts. He has held this position since September 29, 2005. As Chief Justice, Roberts is responsible for presiding over court sessions, leading discussions during conferences, and ensuring that the court operates in an orderly manner. His role is significant not only in influencing the court's proceedings but also in shaping public law through his leadership.

Other names mentioned in the choices were notable figures in the Supreme Court system but have either retired or passed away. Ruth Bader Ginsburg, for instance, was a trailblazing figure known for her work on gender equality and civil liberties, but she passed away in 2020. Clarence Thomas is currently serving as an Associate Justice, and Anthony Kennedy, who was a prominent figure on the court, retired in 2018. Thus, Roberts remains the key figure as Chief Justice, overseeing the workings of the court.
