Wallace was a mainstay on the television program since it began in 1968.

A spokesman says CBS newsman Mike Wallace, famed for his tough interviews on "60 Minutes," has died. He was 93.

CBS spokesman Kevin Tedesco says Wallace died Saturday night.

Wallace was on the staff of "60 Minutes" when it began in 1968, and was one of its mainstays from then on.

He retired as a regular correspondent in 2006 but continued contributing occasional reports. His exclusive interview with pitcher Roger Clemens was broadcast in January 2008.

Wallace was known for spending hours preparing for interviews and for his skeptical follow-up questioning.
