John Roberts

In 1992, President George H. W. Bush nominated Roberts to the U.S. Court of Appeals for the District of Columbia Circuit, but the Senate did not hold a vote on his confirmation. In 2003, President George W. Bush appointed Roberts to the D.C. Circuit. In 2005, Bush nominated Roberts to the Supreme Court, initially as an associate justice to fill the vacancy left by Justice Sandra Day O'Connor, but promoted him to chief justice after Rehnquist's death. Roberts was confirmed by a Senate vote of 78–22, becoming the youngest to serve in the position since John Marshall.
As chief justice, Roberts has authored majority opinions in many landmark cases, including ''National Federation of Independent Business v. Sebelius'' (upholding most sections of the Affordable Care Act), ''Shelby County v. Holder'' (limiting the Voting Rights Act of 1965), ''Trump v. Hawaii'' (expanding presidential powers over immigration), ''Carpenter v. United States'' (expanding digital privacy), ''Students for Fair Admissions v. Harvard'' (overruling race-based admission programs), and ''Trump v. United States'' (outlining the extent of presidential immunity from criminal prosecution). Roberts also presided over the first impeachment trial of President Donald Trump before swearing him into office in January 2025. Provided by Wikipedia
