Which of the following was appointed by President Reagan?

Antonin Scalia was appointed by President Ronald Reagan to the Supreme Court in 1986. His confirmation marked a significant moment in the Court's history, as Scalia was known for his originalist interpretation of the Constitution, which became influential in subsequent judicial philosophy.

The other individuals mentioned have different connections to the presidency and the judiciary. John Roberts, for example, was appointed by President George W. Bush in 2005, making him a more recent figure in the judicial landscape. Richard Durbin and Daniel Inouye are both long-serving U.S. Senators, with no connections to Supreme Court appointments by President Reagan. Durbin, a Democrat from Illinois, and Inouye, who served from Hawaii, are known for their legislative contributions rather than judicial appointments. Thus, Antonin Scalia is distinctly linked to President Reagan’s administration in the context of Supreme Court appointments.
