John G. Roberts Jr.

About

Chief Justice John Roberts has led the Supreme Court since 2005. Appointed by President George W. Bush, he is often seen as the Court's center-right swing vote. Roberts has authored some of the most significant opinions of the current era, including the landmark Loper Bright decision overturning Chevron deference and the presidential immunity ruling in Trump v. United States. He is known for his institutionalist approach, often seeking to preserve the Court's legitimacy through incremental rather than sweeping rulings, though recent terms have seen several major doctrinal shifts under his leadership.
