John Glover Roberts, Jr. (born January 27, 1955) is the 17th and current Chief Justice of the United States. He has served since 2005, having been nominated by President George W. Bush after the death of Chief Justice William Rehnquist. He has been described as having a conservative judicial philosophy in his jurisprudence.
Roberts grew up in northern Indiana and was educated in a private school before attending Harvard College and Harvard Law School, where he was managing editor of the Harvard Law Review. After being admitted to the bar, he served as a law clerk for William Rehnquist before taking a position in the Attorney General's office during the Reagan Administration. He went on to serve the Reagan Administration and the George H. W. Bush administration in the Department of Justice and the Office of the White House Counsel, before spending fourteen years in private law practice. During this time, he argued thirty-nine cases before the Supreme Court.
In 2003, he was appointed as a judge of the D.C. Circuit by President George W. Bush, where he served until his nomination to be an Associate Justice of the Supreme Court. When Chief Justice Rehnquist died before Roberts's confirmation hearings, Bush renominated Roberts to fill the newly vacant center seat.
