Who is the Chief Justice of the Supreme Court?

The Chief Justice of the Supreme Court is responsible for presiding over court proceedings, leading the discussion among justices during case deliberations, and representing the judicial branch of government. John Roberts has held the position since his appointment in 2005. As Chief Justice, he plays a crucial role in shaping the Court's agenda and deciding on important legal matters that affect the nation.

The other figures listed have prominent roles within the Supreme Court but do not hold the position of Chief Justice. Clarence Thomas is known for his long tenure as an associate justice, Ruth Bader Ginsburg was a significant figure until her passing in 2020 and was celebrated for her contributions to gender equality and civil rights, and Elena Kagan is known for her work as an associate justice since 2010. Each of their roles is important, but only John Roberts serves as the Chief Justice, making him the correct answer to the question.
