Who is the current Chief Justice of the United States?

The current Chief Justice of the United States is John Roberts. He was nominated by President George W. Bush and took office on September 29, 2005. As Chief Justice, Roberts has significant influence over the Supreme Court's agenda, administrative functions, and is responsible for presiding over court sessions. His role includes guiding discussions among justices and ensuring that proceedings are conducted fairly and impartially.

The other individuals listed, such as Ruth Bader Ginsburg, Clarence Thomas, and Anthony Kennedy, have played important roles on the Supreme Court, but they do not hold the position of Chief Justice at this time. Ginsburg, for example, was a prominent figure until her passing in September 2020. Thomas is currently serving as an Associate Justice, and Kennedy retired in 2018. Understanding who the Chief Justice is and the context of their role is essential for grasping the structure and function of the U.S. judicial system.
