The usually reticent Supreme Court Justice Clarence Thomas will appear on CBS News’ “60 Minutes” later this month to kick off promotion of his new autobiography, set for publication Oct. 1.

Knowledgeable sources say that CBS correspondent Steve Kroft interviewed Thomas at the Court and elsewhere recently for the “60 Minutes” segment. Thomas overcame an initial reluctance about doing publicity for the book, and the report is scheduled to air on the top-rated news magazine show on Sunday, Sept. 30.
