The Ticker: (Weekend Edition): Gotti, Chopra, Gadhafi…

> Tonight on “48 Hours Mystery” for the first time ever, John Gotti’s children, Angel, Victoria and Peter, speak openly about a life shrouded in secrecy and reveal what they knew about the mafia in an interview with correspondent Troy Roberts. From the death of one brother and the trial of their another – nothing, CBS tells us, is off limits.

> Tomorrow ABC’s “World News Sunday” launches a new series called “Happiness, Inc.” Anchor Dan Harris sits down with Dr. Deepak Chopra to talk about spreading his message in a multi-media age.

> Larry King interviewed two world leaders in one day. On Friday, King spoke with Iranian president Mahmoud Ahmadinejad and Libyan leader Moammar Gadhafi. Ahmadinejad aired last night, Gadhafi airs Monday night. The one-on-one with Gadhafi took place at the Libyan Mission in New York, not in his tent, which is now on its way to Venezuela.
