Most recently know for taking on politicians, CEOs, sports stars and other celebrities on the CBS news program ’60 Minutes,’ longtime newsman Mike Wallace has died at the age of 93. Wallace’s news career spanned more than six decades, and in recent years had been slowed by heart surgery in 2008.

Mike Wallace didn’t interview people. He interrogated them. He cross-examined them. Sometimes he eviscerated them.

His reputation was so fearsome that it was often said that the scariest words in the English language were “Mike Wallace is here to see you.”

Wallace, whose pitiless, prosecutorial style transformed television journalism and made “60 Minutes” compulsively watchable, died Saturday night at a care facility in New Canaan, Conn., where he had lived in recent years, CBS spokesman Kevin Tedesco said.
