you've got one more week to tell us why we should choose you for next year's team. you can logon to cnn.com/fitnation. learn more there. also upload your video submission. we're going to train together. we're going to transform your body and your mind. i call it hitting the reset button. that's going to wrap things up for "sg md." time to get you back into the "cnn newsroom" with martin savidge. you're in the "cnn newsro " newsroom," i'm martin savidge. it is great to be with you. it is just after 10:00 p.m. in geneva, switzerland, and right now diplomats are still trying to persuade iran to stop working on a nuclear program. we've just heard from people that were traveling with secretary of state john kerry who say that a deal is very close, but the chances for an agreement this weekend are unclear. let's get to geneva right now and talk to jim, and john kerry

wrapped up a meeting with iran and eu officials. any indication the meeting was productive? >> reporter: it's the second today. they're getting down to the specific wording of this proposed interim agreement, even down to individual words and individual words can have enormous meaning for both sides. one of the key issues, consistent issue, is iran's right to enrich uranium, iran wants an explicit right to the advice. they don't believe that any country has an explicit right to enrich uranium, how they square that circle, that one-word right is the kind of thing they're going over in these talks and it's one of the things that both sides may very well be digging their heels in so, it shows how difficult it is to get to a place where they have about 90% agreement as one of the iranian owe fishofficials told us earli

today to 100% agreement, a document they are happy with. >> there is no press conference or major announcements, so what happens next? >> reporter: well, we know they're talking again. we're waiting for another gathering of the p-5 plus one members, the permanent five members of the security council plus germany following this most recent meeting. presumably to go over what zareif told him in the meeting and we've seen the cycle rebed again and again over the last three days. it's 11:00 in the evening here, no sign they'll end early. there is one backstop that secretary kerry has announced his plans to travel to london tomorrow, but then again we're also told if the talks continue he may have to come back to geneva after that. >> why is it that we seem to get into this, two weeks ago, same thing, dashes off to geneva, did it again and from what i'm just sort of reading between the lines here, it doesn't sound like they've got a done deal. >> reporter: they don't have a

done deal. they do say they're closer, though, they say they're closer than they were two weeks ago. they say they're closer than they were yesterday, but the question is can they bridge that final 10% really? and when you're going down to individual words, you know you're close but that doesn't mean you're going to get there if, you know, one side or the other digs their heels in, because some of these individual words have tremendous meaning for both sides. you know that in iran, the tremendous emotional and political importance of a recognized right to enrich uranium, but you know from the western side, from the american side, that they don't believe that right exists and they also want to set strict limitations on it for iran. so, you know, this is -- they're down to brass tacks now. this is the difficult part of the negotiations. >> uh-huh. but this is totally unscientific, but, you know, what is the atmosphere there? certainly it must have been that reporters and people were on edge, and now, what, we just sort of, oh, well, i guess we'll wait? >> reporter: i tell you, the atmosphere is exhausted, you know, in the days leading up to it, we did hear optimism from

both sides. they're serious. i think the fact that they're still in the room is a good sign because very easily they could throw up their hands in the air and say we're not going to get there. they're clearly trying. both sides know they have a limited window for agreement, political pressure at home, so the fact that they're still working on it is a reasonable sign of hope, gut god knows it's no guarantee. >> the next meeting will take place tomorrow when? >> reporter: no, there's another meeting tonight. we have every indication they're going to keep going tonight. so we could be here until the early morning hours geneva time. >> they're pulling an all-nighter in geneva, thank you very much, we'll stay in touch. moving on, chances are if you are either experiencing bad winter weather right now or you're about to be, and the things could get very bad for thanksgiving holiday weekend. powerful winter storms moving from the west and, of course, that means they're heading east and it's already bad out there in many places. ice building up on the roads in oklahoma and in texas. dangerous driving conditions

reported along interstate 10. that's also in new mexico and texas. and then monday and tuesday, that is going to be a critical time period to see just where this storm is going to track. joining me on the phone, john barton, he's with the texas department of transportation. john, what have you been told to expect there? >> we've been working with the national weather service and they're forecasting that precipitation will continue to fall over the next couple of days and temperatures. and a large part of the state will be below freezing, so they expect de-icing and snow conditions to continue through monday and as you've mentioned, road conditions are poor and are deteriorating, so we would encourage everyone to avoid traveling if at all possible. >> that's a tough thing to say when you're leading up to the thanksgiving holiday. what are you doing to prepare? >> we have crews patrolling our roadways throughout the state and we'll continue to do that 24 hours a day until the storms pass. they're treating our bridges and overpasses trying to keep them

from freezing and several of our roadways, major routes, as you mentioned, interstate 10, interstate 20, interstate 40 and other major roadways to try to keep them passable. but all that we do, of course, is then impacted by continuing precipitation. so, the main thing is we'll be out there patrolling, plowing snow and ice as we can, putting materials out to melt the ice that does form and trying to protect the traveling public. >> and, you know, these ice storms come and go. we know texas has had many of them in the past. where does this rank as far as severity do you fear? >> this particular storm has been ice so far, and it's not as bad as some we've had in the past. but anytime we have ice on the roadway, it's a difficult thing. it's unlike snow and travelers seem to have more difficulty with them. we've already seen several motor vehicle accidents across the state. so, depending on how bad this continues to be, it could get worse, but at this time it's what i would call a medium-size storm for us. >> all right, john barton with the texas department of

transportation. thank you very much for joining us. by the way, we should let you know that the weather will continue to move east and cnn will continue to track it for you as you make your plans to travel for the holidays. please be safe. the obama care website, it has been the butt of many jokes and it's been widely ripped by critics. now the government is taking new steps to try to boost enrollment. the administration will use results of the pilot program that's been working in florida, ohio, and texas to try to get the bugs out of the direct enrollment option section. they'll work with insurance companies to determine if there are issues before, underline that, before even considering making it available across the country. here's a first for the olympic torch. check out this video of divers taking the sochi olympic torp of 50 feet deep into the world's deepest freshwater lake in siberia. on its trek to sochi, the torch has made some unprecedented stops such as the international space station, the north pole and now here.

not many people enjoy taking the redeye, that's the late night flight that goes from california to new york. well, if you think it's tough now, just wait, because soon the person sitting next to you could be chatting on their cell phone all the way there. as you can imagine, the idea is getting a lot of talk and most of it pretty negative. cnn's alexandria field has reaction from fliers at new york's laguardia airport. >> reporter: it could be a case of be careful what you wish for, yes, it would be convenient to be able to use your cell phone on a plane, but passengers also have to prepare for the possibility that that privilege could come at a high price. a proposal to allow airline passengers to use cell phones in flight has travelers talking. >> you might want to talk the entire flight in a loud voice about every single problem you have in your family, blah blah blah. >> i don't think it's correct to be able to have to listen to everybody chattering on the phone. >> reporter: it may not be long before we all say so long to the

idea of just sitting back and relaxing. some international airlines already allow passengers to talk and text. now an fcc proposal could give american air carriers the ability to do the same. >> i would allow the phone call as long as it's short and to the point. otherwise, it would be better that they don't use their cell phone. >> reporter: the flight attendants union was against the idea when it was floated back in 2004. they still are. >> as you know, airplanes fly thousands of feet metal tube in the air and we don't want any kind of situation that could increase any ability to have a volatile situation on board the aircraft. >> reporter: if given the option, it's already clear that some airlines wouldn't be on board. delta air lines says if the fcc changes its policy, will delta allow voice communications on flights, no. but it's a big opportunity for telecommunication companies. service in the sky could have customers paying through the nose. >> this is potentially a multibillion dollar industry for

if you haven't heard this

story, it is staggering in what the impact what may be. a former mches state chemist is on her way to prison for faking test results. she pleaded guilty to 27 counts yesterday including tampering with evidence, perjury, obstruction of justice and falsely claiming to be holding a master's degree. many of the samples she tampered with came from blood cases brought by police and now thousands of those cases could be in jeopardy. well get more from susan candiotti. >> reporter: annie ducan is going to prison after her testimony put hundreds of others behind bars illegally. beyond pleading guilty, she made no personal comments about the havoc created by the scandal. in a lab similar to this one she admits falsifying drug tests, for example, by adding cocaine to samples, tainting trial

evidence. when she was finally caught last year, she tampered logs. the result? look at all these faces. a fraction of the tens of thousands of people, 300 convictions put on hold in boston alone. >> her actions totally turned the system on its head. >> reporter: a review of every case the chemist laid her hands on from 2003 to 2012 is still under way. in the court system, the fallout is staggering. consider the numbers. according to a special counsel's report, more than 40,000 cases have been reviewed involving more than 86,000 drug samples and the analysis of more than 5 million documents. at a cost to taxpayers of at least $7 million and climbing. >> when you throw a stone into a pond, there is a ripple effect. >> reporter: arguably the worst rachel effect felt by plymouth

county district attorney timothy cruz, because of donta hood. in 2009 a cocaine conviction put him behind bars for five years. but when the lab scandal exploded, hood was set free. because ducan had lied on the stand about her credentials claiming she a master in chemistry, after he was sprung he allegedly shot and killed charles evans in this parking lot in a fight over drugs. the victim's family declined to comment. >> there's no bigger pain than somebody being released that goes out and kills somebody. >> reporter: for cops on the beat like stanley david, frustration. >> it's, like, a second -- like a pass, they beat the system once, they think they can beat the system again. >> reporter: which brings us to why, why did she do it? she declined our request to explain, but her lawyer says the mother of a disabled young son only wanted to help her career, taking shortcuts to get more cases done. never considering the

consequences. >> the furthest thing from her mind is that this is going to ultimately cost millions of dollars, it's going to throw the entire massachusetts criminal justice system into a tailspin and thousands -- >> which it has. >> absolutely it has. >> reporter: chen she was led away to serve a minimum of three-year sentence, authorities suspect it could take at least that long to reconcile thousands of cases and restore faith in the state's criminal justice system, susan candiotti, cnn, brockton, massachusetts. >> as we said amazing and really the tip of the legal iceberg. joining me to discuss this is jeff gardere and holly hughes. 40,000 cases could be impacted by this work or maybe lack of work. what was going through her mind or how does a person justify doing something like that? do you have any idea? >> well, a lot of people are wondering what is going on. no clear answers. we do know that by dry labbing, in other words, not testing the

contents of the samples that was sent, she was giving quick turnarounds to the prosecutions primarily and, therefore, was able to get in more and more cases and build a reputation of having this very, very quick turnaround and being superefficient. so, what we're seeing is this was about advancing her reputation as much as possible. when we look at something like this, let's not be fooled by the fact that she seems to be very petite, seems to be attractive, this is what we call sociopathic behavior. in other words, doing whatever she can to just advance her own life, her own career, maybe taking care of her child, but not even thinking about the consequences on the lives of so manny others, people just put in jail and may not be guilty. >> hold on, doctor, because i want to bring in holly hughes here. we were talking about. she was trying to burnish her record but she's a state

employee so she's not going to get anything. that's not my question. my question is, there have been so many cases, 40,000, what happens? do they get thrown out? >> what they do what they do in the law is what they call a harmless error test. a review is going to be done. it's possible in a lot of the 40,000 cases guilty pleas were enter, they didn't go to trial. if they take a guilty plea, they stand up before the court, and the court asks a series of what we call boykin questions, based on a supreme court case, and they say do you know you are giving up these rights by pleading guilty and then they say are you guilty? and if they've admitted guilt, it doesn't matter if the woman may or may not have done her job properly. they'll look at the ones that went to trial, and the court will look at all the evidence when they review it, was somebody else testified, was a co-defendant on board, yes, that's the real deal and i'm guilty of selling cocaine and, by the way, he was in on it, too. >> the lab result may not have been the only evidence they had.

>> in those instances, the court could say it's harmless error because the other evidence bolstered the conviction. >> it is possible that some may have been wrongly convicted or at least accused as a result of this lab work. how does a person handle that? >> well, certainly i know she must be and i hope she's feeling some guilt. it seems that she is. and as the prosecution said here, she wasn't even aware that she's turning the legal system upside down. she had an overwhelming -- martin, she had an overwhelming urge to want to please others, to please the prosecution in these cases and she did it to the point of where she just didn't even think about how many people's lives that she may have been destroying. >> yeah. obviously she didn't. holly, we know that, of course, she's gone away to prison. >> right. >> is it possible people could sue her? could the state sue her or could even families? >> actually individual families certainly can, if it falls within the statute of

limitations, i expect we'll see lawsuits based on intentional infliction of emotional distress, what you've put these people through, men and women alike, that have been sent to prison because you were just too lazy or too wrapped up in your own ego to do the job properly. i think we're going to see some of that but we also need to remember any attorney that's approached about bringing one of these cases is going to look at the reality and is there anything to recover. i mean, it's nice to make a point, martin, yeah, we want the principle that she should be held accountable, but if she doesn't have anything for these people to recover. but i think some people are going to sue the state. i think they're going to say you should have known this woman was doing this, i think the state is the in for a lot of lawsuits. >> we're going to end the talk on this, but we're going to continue our conversation on the law and those involved. jeff, holly, stay here. here's a story for you. one man charged with terrible crimes and he claims he didn't do it. and get this, he says it's his twin. what does the dna evidence say? you'll be surprised. that's next. so, with chevy's black friday sale,

this may sound like something out of a soap opera, i actually think it was the plot of a soap opera at one point. the man takes the blame for the actions of his evil twin, this scenario, though, is playing out in a real colorado courtroom. a soldier claims that his identical twin brother is the one that's responsible for the sex crimes that he is now accused of. we get more from cnn's miguel marquez. >> reporter: it is brother versus brother, identical twins, aaron lucas a decorated army officer is charged with trying to lure 11 girls between 6 and 9 years old into his vehicle and sexually assaulting three of them. all this while on active duty at ft. carson in colorado springs. do you have any questions, sir? >> no, your honor. >> reporter: dna linking him to

alleged sex crimes in two other states but aaron lucas said his identical brother brian is to blame for some or all of the crimes. dna was taken from aaron lucas when he was arrested last year. the sample posted to a national database linked him to unsolved sex crimes in madison, alabama, and texarkana, texas, there is, however, one possible exception. identical twins have virtually identical dna. both brothers lived in alabama and texas. brian says he's never been to colorado springs and law enforcement agencies in alabama, texas, and colorado say aaron lucas remains the focus of their investigations. defense attorneys say beyond the dna evidence, one alleged victim described their assailant as driving a black acura sedan, a car similar to that owned by aaron's twin brother, brian. the defense also says another witness identified a different man altogether as her assailant. all evidence the judge says a

jury can now hear. still unclear whether brian lucas will be compelled to appear in a colorado court in a case expected to start in january. miguel marquez, cnn, los angeles. >> thanks, miguel, for that breakdown. let me bring back now clinical psychologist dr. jeff gardere and defense attorney holly hughes. holly, how will you prove who's really responsible here? >> you're going to look at evidence besides dna, if there's any fingerprints, identical twins don't have identical fingerprints and they'll look at that. they'll also look at alibis, if the brother brian can prove he was somewhere else and the dna matches it's got to be the brother who's charged with the crime. they're leaking at albis and additional, like we talked about the car. miguel told us, somebody said it was a car like the brother's. okay, but was it the brother's? they'll look at all of that additional and you ask, you know, do you think brian will be called into court? i do. and do you know who is going to

call him? the state is going to call him to say, did you do this, and he's going to say absolutely not, and here's why. he's going to list out every alibi he has and some of those attacks he wasn't even in the state at the time they happened. >> all right, dr. gardere, let me ask you this, is it common for this sort of good twin, bad twin scenario? >> not usually, because what we're looking at, right, is the same dna when we look at studies done on identical twins, we try to match up the behavior even if they've been separated at berth. we find that they have -- they both share the same kinds of behavior. though we have seen cases like this and holly can speak to it where one twin has blamed another for whatever trouble they seem to get in. so, this is what muddies up this thing, and, of course, a third suspect. but, no, we usually see some of the same behaviors or at least the outline of some of the same behaviors. >> yeah, well, we used to, you know, obviously talk about this as twins with kids because they think they could get away and

blame the other but we're talking about something far more serious. has there ever been this kind of evil twin defense? >> there has been, several times in a courtroom, and it doesn't work because of those other factors. sometimes there's a tattoo that one twin has that the other doesn't. a lot of time if there's a sexual assault case you'll see bite mark impression. teeth aren't going to be the same. over the years one twin gets a cavity, a filling, the other one doesn't. so there's always a way to sort of distinguish them, so it has been tried. it has not been successful in any of the cases that's been used in thus far. >> well, let me ask you, this dr. gardere, and this is obviously we're just saying sort of what if, these are terrible accusations that have been made for luring very young girls. so, say, it wasn't him and eventually it's proved that it was somebody else, maybe the twin. what is the impact likely to be on that person who's been accused of this? >> even if he's found not guilty of this, the fact that he's been accused of being a pedophile, raping three of these -- of

youngst youngsters, is something that he's going to have to live with forever and people are still going to have doubts, and they'll ask, well, why is it that he was raised perhaps in the same household with this evil twin, does he have some of this same behaviors because of the genetics that he hasn't acted out but is he someone that can be trustworthy, so this thing does get very complicated. by the way, they're coming up with new dna tests because we find that dna does change over time because of the impact of the environment. so, they're not going to have this kind of an issue in the future, but still, we're waiting on that test to come to fruition. >> fascinating. actually, two fascinating cases, dr. jeff gardere, holly hughes, attorney, thank you both for joining us, we thank you very much. >> thanks, martin. for some of this week's remembrances for john f. kennedy it's put into sharp focus how far back obama's approval rating has fallen since the early sky high numbers. years from now, how might

unfulfilled presidency. so, it was very limited. a lot of the things that could have gone wrong in the next few years, a lot of the problems that set in once a president is in office for a while, we don't know, so it remains an open question, and i think we imagine the best about what would have happened. >> okay, so moving on from kennedy to, of course, lyndon johnson for the second half of the 20th century, only richard nixon's were lower than lyndon johnson's, even though he passed the civil rights act where kennedy failed, so why is johnson remembered with such, i guess, low esteem? >> yeah, it's an amazing story given how much more legislation went through during johnson's presidency. the big answer obviously is vietnam and the war was so unpopular, so divisive, and had such a damaging effect on the president's party that that's what we remember him for. and it overshadows many huge accomplishments like the creation of medicare and medicaid and the civil rights and voting acts of 1965, but war

can destroy how we remember a president and no one knows this as much as lyndon johnson. >> there are some people that actually associate johnson maybe in some way connected with a conspiracy to kill kennedy. do you think that weighs in in any way? >> i don't know. i think that's still a very fringe view, i know there's a new book about it. but i really think it's about vietnam and the divisions that his successful policies did as well. success often breeds controversy and that was a case with a lot of his civil rights initiatives which opened up fights even though they were meant to resolve the issue of racial inequality. >> well, and this is really sort of a way to bring it into modern day, because how much of president obama's legacy will be tied to, say, obama care, if it isn't fixed? how much does this hurt him? >> well, it's going to be huge. there's no war like vietnam thus far that's going to overshadow what he did, so it's really going to come down to this health care program. that's how presidents are really measured in most cases, what

they do, what they put forward and how the programs work over time. so, he has a lot riding on this. not just for the policy itself but for how we remember him over time. >> so if it were to fail or if it just continues to be this program that can't seem to get it right, that ruins eight years? >> it doesn't ruin eight years. there's other parts of his presidency, but this is the high profile piece of legislation. he has defined himself around this bill. so, if it's a program that doesn't work or is dismantled, even worse, i think it's going to be the first thing or one of the first things we write about his presidency, rather than his being a transformative president or a president who solved the biggest issues in domestic society. so, i do think it could have that effect. >> well, we've still got a long way to see how that is written. political historian, julian zelizer, always a pleasure. thank you. >> thank you. do you think you have the

stuff to be a hero, a warrior, maybe a jedi, thousands showed up to prove they do. because there's a "star wars" casting call this weekend. we'll tell you where, coming up.
