Mike Wallace in the hot seat on 60 Minutes

In-your-face television journalist Mike Wallace answers some tough questions on this Sunday's edition of 60 Minutes. The 88-year-old news veteran is retiring from the program and revealing a lot about his personal life, including the revelation that he attempted suicide 20 years ago. He had a roundtable discussion with fellow 60 Minutes jouralists Ed Bradley, Steve Kroft, Leslie Stahl and Morley Safer, who got his old friend to open up about his battle with depression. Wallace also says that, since his suicide attempt, his life has been better. It's not clear whether he admits how he tried to kill himself.

The retrospective, called I'm Mike Wallace, airs Sunday at 7 pm on CBS. It also includes clips of some of his most memorable interviews.
