Courtney wild, another one of his accusers telling ABC news about an alleged encounter when she was just 14. I was 14, I had braces on, like I remember standing in his kitchen and like gash and he also had a lot of girls there all the time. Reporter: In 2008 the Florida broker struck a controversial secret plea deal serving 13 months in a county jail on state charges registering as a sex offender but securing immunity from federal charges in Florida for himself and his alleged co-conspirators. The federal prosecutor who authorized that deal, secretary of labor Alexander Why would you cut this deal with Jeffrey Epstein? Why would you immunize not only him but all of his friends and employees and everyone who helped him get away with this big scheme? Michelle Licata telling ABC news overnight this is the day she's been waiting for. The first moment finding out Jeffrey Epstein was put in jail was so relieving to me. I felt safer. I've waited for this one day just to happen and it's finally come. Now both Michelle and Courtney are set to attend his court hearing later today where we are all sure to learn more about the specific charges leveled against him once that indictment is unsealed, George. Thanks. Let's bring in Dan Abrams for more on this. This will be the first time he faces federal charges even though federal prosecutors did write a draft indictment last time. Last time he pled guilty to two relatively minor state charges and part of the deal basically putting together the federal and state and saying, look, we're putting this all into one bucket and we're saying to you, plead guilty to these two state charge, we'll make sure you're not prosecuted on the federal charges. That deal is technically still in place so the question becomes how are they now charging him? We'll learn for sure today. It's being run by the southern district of New York but also the public corruption unit. He's not a public figure. That's right so two questions. First, how do they get past this nonprosecution agreement and the answer these have to be new allegations. These have to be ones not covered in that 53-page -- To avoid double jeopardy. And avoid this nonprosecution agreement. Then you're right, very interesting that the public corruption unit. They have a unit that deals with sex trafficking and appear to be a minor part of this which should be O Epstein because the question then becomes, well, what were they investigating? And could there be additional charges here beyond the ones that we're seeing, so that's got to be something from his per -- He's connected to powerful wealthy figures. It's true and that's what apparently helped him last time but I don't think people should be concerned about that this time around? Why? Because these are prosecutors that went out of their way to indict him. There is a nonprosecution agreement in place. You want to make this go away, you can just say, you know what, there's a nonprosecution agreement, this case is done. These prosecutors have basically said this is serious enough, we're going to go out. We'll find these additional victims and it seems and move forward with this case anyway, so I think that the sort of idea he's got well connected friends will help him this time around very unlikely. Dan Abrams, thanks very much.
