John Roberts is the **Chief Justice of the United States Supreme Court** and one of the most influential figures in the US judicial system. Appointed in 2005, he has shaped major rulings on constitutional law, federal power, voting rights, and the scope of the courts’ authority.

## Professional career

John Glover Roberts Jr. was born in 1955. He studied at **Harvard College** and **Harvard Law School**, where he edited the Harvard Law Review. After graduating, he served as a law clerk to Judge **Henry J. Friendly** of the United States Court of Appeals for the Second Circuit and then to **Justice William H. Rehnquist** of the United States Supreme Court.

Roberts later worked in the US Department of Justice and in the White House Counsel’s Office during the Reagan administration. He then entered private legal practice, including work as an appellate lawyer.

In the **George W. Bush** administration, Roberts was first nominated to the United States Court of Appeals for the District of Columbia Circuit in 2003, but that nomination was not acted upon before the Senate. In 2005, Bush nominated him to be Chief Justice of the United States after the death of Chief Justice Rehnquist. Roberts was confirmed by the Senate and began serving as **Chief Justice of the Supreme Court** in 2005.

As Chief Justice, Roberts has presided over the Court through major cases involving the Affordable Care Act, same-sex marriage, campaign finance, administrative law, abortion, and electoral disputes. Although identified with the Court’s conservative bloc, he has at times been described in public debate as a **conservative-moderate swing vote**, depending on the issue.

Roberts appears frequently in public debate because he leads the United States Supreme Court, the country’s highest court, and because his vote has often been pivotal in closely divided decisions.
