Andrew Madoff says he never suspected his financier father of running a Ponzi scheme because he grew up hearing what a legend he was.
He says people had an incredible vision of Bernard Madoff as a "spectacularly skillful trader."
Their appearance coincided with the publication of "Truth and Consequences" by Laurie Sandell. It contains extensive interviews with family members.
Andrew Madoff says the book provided an opportunity to say in their own words what had really happened, and "to speak to the thousands of victims I don't know."
Ruth Madoff says she doesn't miss her husband. She says: "The villain of all this is behind bars."
