Associate Justice, U.S. Supreme Court (1991-present)
Background
Clarence Thomas has served as an Associate Justice of the Supreme Court since 1991, appointed by President George H.W. Bush following the retirement of Thurgood Marshall. He is consistently among the Court’s most conservative voices and has written opinions arguing for broad presidential removal power over executive branch officers, a core tenet of Unitary Executive theory. Thomas is the longest-serving current member of the Court and has been a central figure in its rightward shift over three decades.
