Arlen Specter (Pa.) as Judiciary ranking member, said in a statement.

Sessions’ staff additions include new staff director Brian Benczkowski, who most recently served as chief of staff to former Attorney General Michael Mukasey, and deputy staff director Matt Miner, currently the chief counsel on the Judiciary Subcommittee on Administrative Oversight and the Courts.

Joe Matal, formerly the counsel to Sen. Jon Kyl (R-Ariz.) on the Judiciary Subcommittee on Terrorism and Homeland Security, will serve as general counsel.
