Bernie Madoff, the infamous entrepreneur and investor who operated one of the largest Ponzi schemes in American history, is speaking to the media as part of a resurgent interest from the public in conjunction with his estranged wife's 60 Minutes interview.

ABC correspondent Barbara Walters spent two hours speaking with Madoff in prison, though she does not have video footage of their conversation because of filming restrictions in the prison. Walters says Madoff has terrible remorse. He knows he ruined his family. During the daytime he doesn't think about it, but at night he battles horrifying nightmares.

While he was in jail, he thought about suicide, but he didn't have the courage, said Walters.

She also revealed some startling information about Madoff's comfort in jail: I feel safer here than outside. I have people to talk to; no decisions to make. I know I will die in prison. I lived the last 20 years of my life in fear; now I have no fear because I'm no longer in control, said Madoff according to Walters.

Bernie Madoff's wife, Ruth Madoff, will be featured on 60 Minutes this Sunday. In the soon-to-be aired interview, Ruth tells CBS News that both her and Bernie tried to kill themselves on the Christmas Eve after Bernie's Ponzi scheme was made public.

In a Telegraph report, a security guard says that he does not remember anything unusual the night that Ruth is speaking about in her 60 Minutes interview and questions the legitimacy of the claim. Andrew Madoff, the surviving son of Ruth and Bernie, is also featured in the 60 Minutes interview. His brother, Mark, hung himself in Manhattan apartment in late 2010.

The wife that survived Mark, Stephanie Madoff Mack, has also been making headlines as she's begun to speak out against Bernie and blames him for her husbands suicide. Her recent public appearances come just as her book, The End Of Normal, has been released.
