John RobertsJohn Glover Roberts Jr. (born January 27, 1955) is an American lawyer and jurist who has served as the 17th chief justice of the United States since 2005. He has been described as having a moderate conservative judicial philosophy, though he is primarily an institutionalist. He has shown a willingness to work with the Supreme Court's liberal bloc, and has been regarded as a swing vote on the Court.
Roberts grew up in Northwest Indiana and was educated in a series of Catholic schools. He studied history at Harvard University and then attended Harvard Law School, where he was managing editor of the ''Harvard Law Review''. He served as a law clerk for Circuit Judge Henry Friendly and Justice 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, during which he was nominated by George H. W. Bush to the U.S. Court of Appeals for the District of Columbia Circuit, but no vote on his nomination was held. Roberts then spent 14 years in private law practice. During this time, he argued 39 cases before the Supreme Court. Notably, he represented 19 states in ''United States v. Microsoft Corp.''
Roberts became a federal judge in 2003, when President George W. Bush appointed him to the District of Columbia Circuit. During his two-year tenure on the D.C. Circuit, Roberts authored 49 opinions, eliciting two dissents from other judges, and authoring three dissents of his own. In 2005, Bush nominated Roberts to the Supreme Court, initially to be an associate justice to fill the vacancy left by the retirement of Justice Sandra Day O'Connor. Chief Justice William Rehnquist died shortly afterward, however, before Roberts's Senate confirmation hearings had begun. Bush then withdrew Roberts's nomination and instead nominated him to become Chief Justice, choosing Samuel Alito to replace O'Connor.
Roberts has authored the majority opinion in many important cases, including decisions relating to elections, federal agencies, presidential power, the Affordable Care Act, and race-based college admissions. Provided by Wikipedia
