Who is the current Chief Justice of the United States?

The current Chief Justice of the United States is John Roberts. He was appointed to the Supreme Court by President George W. Bush and took his oath of office on September 29, 2005. As Chief Justice, Roberts holds a crucial role in overseeing the operations of the Supreme Court, presiding over court sessions, and ensuring the justices follow proper procedures. His leadership style often emphasizes consensus and seeks to foster a unified approach to decision-making among the justices.

The other individuals listed have had significant roles in the Supreme Court; however, they do not hold the position of Chief Justice. Ruth Bader Ginsburg served as an Associate Justice until her passing in September 2020, while Elena Kagan and Clarence Thomas are also Associate Justices, each contributing to important rulings but not serving as Chief Justice. Thus, John Roberts is correctly identified as the current Chief Justice as of October 2023.
