R.I.P. Mike Wallace

CBS newsman Mike Wallace, the dogged, merciless reporter and interviewer who took on politicians, celebrities and other public figures in a 60-year career highlighted by the on-air confrontations that helped make "60 Minutes" the most successful primetime television news program ever, has died. He was 93. Wallace died Saturday night at a care facility in New Canaan, Connecticut, where he had lived in recent years, after many years of heart issues.
