>> welcome to al jazeera america. i'm john siegenthaler in new york. here are tonight's top stories. west virginia authorities have asked a company to remove chemicals that contaminated a water supply. people still don't have safe tap water. federal authorities are investigating. target's massive data breach keeps getting larger. now the company says up to 110 million people could have been impacted. and hackers could have stolen even more information than originally thought. hundreds of documents were released today on governor chris christie's bridge scandal which shows state are officials

scrambling to control the damage there. craiftie apologizes for the lain closure, which were political pay back and fired a top aide yesterday. india has asked an american embassy authority to leave. arrested in new york city last month. she returned to new delhi this morning despite facing charges in united states including visa fraud. i'll see you here at 11, 8 pacific, consider this with antonio mora is next. remember can you get the latest on aljazeera.com. >> chris christie's hope to escape scandal hit another roadblock. about 2,000 pages of documents that could bury his former aids.

weighing in on everything from christie to north korea. how thousands of members of one rap group as a gang? hello i'm antonio mora and welcome to "consider this". >> we begin with an avalanche of new documents that appears an elaborate political coverup of individuals loyal to chris christie. christie flew to florida over a political trip but the scandal over the bridge is clearly not going away. new jersey lay makers released e-mails from christie's aids seemingly trying to hide the lane closure with a supposed traffic study. joining me is jordan johnson, his constituents of

fort lee, new jersey, hit hard in the george washington bridge scandal. good to have you with us. what's your take away? >> it adds to my feeling that the firing or the termination of ms. kelly does not get to the crux of the matter. and realizing when you fire somebody you still don't get to the truth. i think there's a lot going on there. in e-mails shows us there's some conflict maybe a contempt between new jersey and new york at an administrative level that exists. i know that on the new jersey side it appears to be a atmosphere of intimidation and fear. lead by intimidation, by these political employees put there by chris christie. >> let's talk about that new jersey and new york conflict. there are a lot of angry exchanges come out in this

e-mail. bill baroni, who is the top person to the port authority in charge of the george washington bridge, between him and patrick foy. foy says to bar oni after being upsaid -- baroni, he says bill we're going to fix had fiasco. baroni says i'm on the way to the office to discuss. there can be no public discourse. if everything is above board, why would baroni not want to have any public discourse? >> exactly. right now we know there was no traffic study, it was done for political pay back for some reason. and the new york side was made aware of it apparently. so these are individuals put there by our governor, who wanted to exact some revenge for

somebody on the new jersey side. >> what do you think of christie himself? there is history of him being pretty tough on people he disagrees with. this is normally a guy who has common sense, a smart guy, do you think he would have been involved in something as stupid as this? >> i don't know and we don't know if he was directly involved in this but i sincerely doubt that ms. kelly, the one who was dismissed? was the -- was the only one who initiated this action from his inner circle. i don't believe that she would run a rogue operation from this inner circle. we all know mr. christie runs a very controlled operation, there wouldn't be someone in his administration who didn't know something about it. >> one involved david wield wild

stein who took the fifth when questioned about this. he wrote an e-mail to christie's staffer, the new york side gave fort lee back all three lanes this morning, samson helping us retaliate. samson is the chairman of the port authority. now this is saying that even the chairman of the port authority might have been involved in all of this. >> not only was mr. samson the chairman but he was nominated by chris christie forthat position. there is -- for that position. there is a very close tie there. when i attended these monthly board meetings, commissioner board meetings in october, november, december when all these commissioners were there including the six from new jersey trying to seek answers for this traffic chaos that was going on, you going to try convince me that none of these individuals, the six individuals from new jersey because we have 12 commissioners, six from jersey, six from new york, of

the six new jersey commissione commissionerrers picked by chris christie, we have elected officials acquiring about what's going on? -- inquiring what was going on? this doesn't make sense to me. >> this is now a collaboration lawsuit. let's listen -- there's now aclass action lawsuit. >> let's listen to some of the people. >> it was frightening and caused craziness. i started to get very, very anxious, it escalated to a point where i had an actual accident. >> if he was really unaware of this i think that strains credulity myself. >> i think people should be held accountable for their actions. >> i feel outraged. i feel insulted. i feel taken advantage of, inconveniented. >> outraged insulted. try to give me your assessment. how outraged should people be?

>> they should be very outraged. just trying to get to work in a day. this four hour traffic jam, people couldn't get to their shops and stores to buy services or products. it's just -- i just can't believe or don't understand why swuns of the governor's office, we don't know it was the governor but someone in his very small circle of confidentes would do something like this. >> the small smoking gun, where do you see this going in the next week? >> we plan, i say we. we in the transportation committee which i will be sitting in on, plan to subpoena ms. kelly, and of course our first step is to get the resolution in, that will allow the transportation committee to subpoena, give them subpoena powers for their next section because our session ends tuesday, new session starts

wednesday, a new session for the speaker is to have a vote which would allow the transportation committee to continue their investigation through the subpoena power that will be given othem. >> and you'll see where that investigation takes you. >> and we'll see where that takes us. it will be a long year but we'll get to the bottom of this. >> new jersey assemblyman gordon johnson we thank you for coming. >> i'll be glad to come back to give you the follow up. >> thank you. >> thank you. >> for more, bill richardson, former u.s. ambassador to the united nations, and the author of the new book how to sweet talk a shark, strategies and stories from a master negotiator. joins us from washington, d.c. great to have you with us governor. as someone who was the chief executive of a state is it possible that chris christie did not know what his staff was doing? >> well, it is possible and he was very candid, and let it all out yesterday in his press conference. he's going to have to be right,

i think he can't afford to, in the future, to show that he had any connection. because he was pretty forthright. but i will say, it does damage his ability to project bipartisanship, that he's a tough guy who gets results. because this was a bad incident. but i give him the benefit of the doubt, having been a former governor, that possibly he didn't know. >> you know one of the things that people have brought up is that even if he didn't know, is it a question of the culture that he created? i know that you had ieshts with some of your -- issues with some of your own staffers in new mexico. but do you think it is possible and that he has responsibility if his staffers thought that this is something that chris christie would have thought this was okay? >> well, the governor sets the tone. but i think what, rather than it

governor christie on this. the attitude of these staffers, vindictive petty retribution, he didn't get endorsed so let's go after that mayor. perhaps indicative if he wants to jump into the presidential waters he needs a broader view, more critical staff that is able to say, to him, governor we're wrong in doing this or that isn't so petty. so i think it's more a question of if he wants to move into the big leagues he's goth to get a stronger staff. >> independence of what this might mean about hit presidential ambitions, how strong would a scandal like this make it to govern? >> it's early in his second term. he tried put everything away in one press conference by i must say being candid, admitting the mistake. it just remains to be seen what will happen in the days ahead. if there are other e-mails, if it does linch him more -- link

him more directly. but possibly he has at least stopped the bleeding at this point. but he's going to get more scrutiny. when you run for president, everything you do is scrutinied. so -- scrutinized. so he has invited more scrutiny. he has to rise above this bee debacle. it wasn't a plus. and get some new tone. >> you have been involved with the north koreans, you have traveled, there were a number of times sings the 1990s. what was your reaction to what happened to dennis rodman. >> i had initially thought that dennis rodman, basketball diplomacy, ping pong diplomacy with china that helps sometimes, it's not just the traditional diplomats. but after this last debacle of

dennis rodman of basically hinting that kenneth bae the american detainee was possibly guilty single happy birthday to kim jong-un's birthday, being a mouth peace the propaganda of dennis has totally in my view undermined his ability to use basketball diplomacy to better. i hope he has left town, left north korea but i was disappointed. bought i am -- because i am an advocate of out of the box diplomacy. he is the only one to get in to see kim jong-un. i tried and failed. but he should have pushed to get kenneth bae the american detainedetainee out. he didn't try that. >> do you feel there is any room

for optimism that cebbette bae will be released? >> i'm concerned that the north koreans want to use him as a bargaining chip. it's been over a year. 14 months. this man is not guilty. he's sick. he's got a family. that because we know so little about kim jong-un and his negotiating tactics in the past i could deal with the old regime because i knew more or less where they were coming from. and we were able to get some releases out. but with this young man he seems to be totally preoccupied with his own power base. he brutally executed his uncle. he's replacing generals that he feels are not loyal to him. so he's internally being challenged. the worry is that there might be an implosion there because the young man is not secure. we know so little about him

because this is what's dangerous. north korea has nuclear weapons. we have missiles in the dmc, we have a treaty with south korea. any little incident can get us involved, the united states in a way that can be a real spark a bad spark around the region. >> a lot to be concerned about with a loose cannon. in your book how to sweet talk a shark, you talk about dictators, you were sometimes referred to as the undersecretary of thugs because you dealt with these unsavory characters. you tried get a deal with the castros a couple of years ago to get the release of alan gross. any progress there? >> no, no progress there. in fact i failed antonio. i got all upset because the cubans, i thought we had a deal. the cubans said no, we want the cuban 74, you don't go one for

four, you go one for one. it was a new element in negotiations. instead of playing it cool and resuming my negotiations, cooling off, i wept to the press, and i -- i went to the press and i denounced the cubans they call alan gross a political prisoner. i lost my cool. so i'm not involved in those negotiations anymore. i hope somebody is pushing hard. i know the administration is doing that. but there is another case where this man should come home. he did nothing wrong. he's been there several years. he's not well. there has to be an advocacy for these individuals and sometimes the alan gross case is a big barometer as to whether american and cuban relations can ever improve. >> you are one of the highest profile la te latinos, despite e

fact that it is an election year are you as hopeful? >> i'm hopeful, because i believe if you're any republican, and want to keep control of the house and senate, maybe prepare your presidential candidate to do better than mitt romney did, you need the latino vote, and the latino vote is looking at how members of congress are viewing immigration. whether the antiimmigration reform or pro, and our community is getting bigger, it's stronger more populace. and so if the republicans want to just forgot foresigh forget e latino vote, there are a lot of moderate republicans that are moving in the right direction. unfortunately most are in the senate but in the house even if you get a piecemeal approach and you roll something out in the course of the year five

different elements, the ability for instance the legalization provisions, the border provisions, the provisions that allow individuals with high-level skills to stay in the united states, maybe you do that in the little slower basis in the senate. boehner, i know him, i served in the house with him. he's a realistic guy but he's got a caucus of tea party republicans who make it hard for him to maneuver and do what's best for not only the country but his own party. >> hillary clinton is expected to be the candidate for your party in 2016. yesterday you said that john kerry could be the candidate. is there a chance you could be a candidates yourself? >> you have one shot antonio, you don't keep going and going. i mentioned john kerry. this was my opinion because i think he's been a good secretary of state.

he ran before, ran well. but i don't even know if he wants to do this. he may be very mad at me for having said this because he's doing all this secretary of state stuff. >> and having said that you've had your issues with the clintons. you supported barack obama in 2008 once you pulled out of the race. how is your relationship with hillary and bill? >> not too good. not too good. better with hillary than bill. but you know that's politics and i'm not -- i don't regret anything did i. i think i did the right -- i made the right choice. but hillary clinton is going to be a formidable candidate. i do believe she'll run. and then you have somebody like christie who i think is a possible candidate. this incident will determine how -- whether he makes it all the way. i still think he's -- he's viable. because of his record and his massive reelection victory in new jersey. so if i'm a democrat, you don't

count this guy out. >> well, you've been advocating for the end, of horse slaughter in the united states. and i know that today the humane society named you its horseman of the year. i want to congratulate you for that. i want to thank you very much for joining us. your book is how to sweet talk a shark. former new mexico governor bill richardson. thank you. >> thank you antonio, all the best to you. >> all the changes president obama will make in the nsa scandal. the insane clown pos espans. why is the fbi so intent on tracking it. and janet tavoni is tracking, what's trending jana? >> antonio it's a facinating story. i'll tell you, over $180 to over $7,000, some think it's a move to keep reporters out of the country. more coming up.

and what do you think? join the conversation on twitter @ajconsiderthis. and our twitter and google plus pages. the inquiry had recommended better rail maintenance and supervis

>> will the president rein in the national security agency, the president will share his plan to change the nation's intelligence gathering next friday. >> the president's been clear, throughout this review process, that we will not harm our national security or our ability to face global threats. the goal the president i think has set here is to take measures that create more transparency, introduce reforms that improve the system in a way that gives the american people more confidence. >> so just what will the president's plan look like? we are joined from chicago by jeffrey stone, professor of law

at the university of chicago and one of the five men's chts president's nsa panel that gave the president friction recommendations on how to change the intelligence agency in a way that would protect the privacy and the civil liberties of the american people. jeff great to have you on the show. how far do you expect president obama to go? as we said 46 recommendations, how many do you expect will be implemented? >> well i hope he imlelts the vast majority of-- implements the vast majorities of them. i don't have any inside information on that. my guess is he will adopt the vast majority. i'm pretty confident of that. >> which ones do you think are most important? >> as far as the american public, the section 216 metadata, the one in which nsa collects phone records of american citizens and then it utilizes that information when it has reasonable grounds to believe that a particular phone number belongs to a terrorist,

then queries that database to see whom that terrorist may be speaking with. it is obviously gathering up a huge amount of information and our regulations obviously call for a number of changes in the program that are designed to enable to continue to serve the purpose that it does in terms of protecting the nation. but at the same time, to be more respectful of interests to privacy and transparency and to make sure there's a greater degree of judicial oversight of the use of the metadata. >> by keeping the metadata at the telecom companies? >> not to allow the nsa itself to hold the databases. >> fbi director james comey, customer communications and the argumentative in general from supporters of the intelligence community has been after 9/11, you shouldn't be handcuffing any

of the intelligence community's efforts to keep the home land safe. how do you respond to that? >> well our view is that this requirement would not handcuff the intelligence community. basically a requirement of a jucial order is what we do for search warrants and wide range of other situations, and that we recommend that there be an emergency exception. so to the extent that time is fs essence and going to a judge for such an order would in fact impair the ability of the fbi to be effective they would be allowed to go ahead independently with only after the fact review. we don't think this significantly or in any preecial appreciable way, to make the legal determination as to whether there is in fact a legal justification to issue the order. >> and the panel recommended

when it came to the fisa court, there you think there's going to be little opposition that one will go through? >> i'm pretty confident that one will go through. it makes a great deal of sense. when the fisa court was created it was primarily created to deal with the equivalent of a search warrant. even in the norch foreign intelligence context that process normally takes place with only one side presented. the police officer comes in gives the information to the judge, the judge rules. what's happened in the 30 years since the fisa court has been creacted, technology is created an the fisa court occasionally has to decide complex cases, it's very important that the judges hear both sides of the case and so our recommendation -- yeah go on. >> the workings of the court would be still completely

classified, how would you have any oversight to ensure that the advocate was being effective? >> well, the advocate would be effective in the same way that in the context of any classified system, you have talented committed people who do the work. right now there is no other side being presented. the fisa's work itself is classified. it's important to remember that before the fisa court was created the president could do all of this entirely on his own with absolutely no judicial supervision. when the fisa court was created, the president no longer could do this on his own initiative he had to get court approval. this builds on that, when the court is dealing with an issue that is legitimately controversial there needs to be both sides represented. i believe the president will accept that recommendation. >> you are also putting out recommendations suggesting or protecting foreigners, people nonamericans abroad. is that police? people would say you know we're

supposed to be spying on people abroad especially if it's in order to protect the united states. >> well, of course we are supposed to be spying on people who pose a danger to the united states. but we have a variety of different interests that are -- come into play in deciding how to strike the right balance. one of them is our relationships with other countries. it is important to us especially with our allies that they feel that we're treating their citizens in an appropriate manner partly because we want them to treat our citizens in an appropriate manner partly because we have a whole seth of the -- a whole set whole settlef arrangements. we're supposed to protect a whole set of incidents, basically recognized that we live in a whole international community and at least within certain limits it is important

that we respect the limits and the privacy rights and dignity rights of people throughout the world particularly among our allies. >> jim, another question, if the president finds middle ground, nobody in the end is going to be happy with what he does next week? >> i think there's two reactions. on the one hand nobody, well not nobody, but many people will be upset because he did something or he didn't do everything. an all of lot of other reasonable people, not the ones doing most of the shouting, are going to understand that he made important steps forward, that will protect privacy and civil lebts, without at the same time jeopardizing the security of the nation. i believe that's what he will do. >> jeffrey stone, thank you for your time. >> my pleasure, thanks for having me. >> turning to the fbi, after labeling fans of a rap group as a gang.

jugaloos, as a hybrid gang and its 2011 national game threat assessment report. the aclu has now joined the band and suing the fbi and department of justice arguing that the gang label is unwarranted and that it's negatively impacted the band's business and the lives of their fans. fara haddad, considers himself a jugaloo, does that make you a gang member? >> i guess that makes me a gang member who happens to be alawyer. early on when this case started they coined me the juggalo lawyer. there are several police officers i've interviewed there

are several people who you know work, your normal 9:00 to 5:00 job. there's professors, there's doctors. so i guess we're all part of some loosely organized hybrid gang according to the fbi and that's what we're trying oget to the bottom and change. >> the obvious question is how do you designate hundreds of thousands of people of being part of a gang for liking a band? >> that's a good question. we're very perplexed by it. the first lawsuit that we filed back in 2012 was because we did it exactly a freedom of information request to find that out. what we finally got after a lot of hard work was stuff that was totally unrelated, to anything that would be considered an organized criminal gang. and really, what we found was, there was certain crimes, random crimes around the country with people who happen to be wearing

an icpt shirt or have an icp logo on their myspace page and police said they were part of this group and that's why they committed vandalism or larceny or something like that. >> well, in that gang threat assessment in 2011 the fbi said a robbery or a beating of a homeless man by a pair of juggaloes. but has there been any organized group criminal activity that would lead the fbi to label the group as a gang? >> not that we know of. none that the fbi has reported to us, and again we've tried very hard to get that information from them. >> why do you think they did it? and has any other band's fans been targeted in a similar way? >> well, here's what i liken it to, antonio.

and basically, there's millions of dead heads and obviously the dead heads are -- there was at one point an investigation by the fbi into the -- some fans that considered themselves dead heads selling lsd at concerts. that's about as close as it has been, there has never been that series as a gang classification. but you can sort of look at it as hip pies in general, a subculture that has formed itself around a genre of music. it's not mainstream music obviously. and if the fbi labeled all opposed hippies a gang, i think that would be ridiculous. since they don't know what juggaloes are, they hesitate and not sure whether this is right or wrong. i have several examples i can give you such as the plaintiffs

in a lawsuit of ways this has really affected people in ways that you probably can't even imagine toant. >> i want to get to those issues in a matter but let's go to janna. >> i know a few juggaloes, they consider themselves a gang and cover up for themselves, how do you react to this? >> well, there's different reports, whether there's hundreds of thousands of juggall-oes nationally, any group of people you might have some, you could have fans of gang sister rap for instance, fans who consider themselves real gang sisters, that doesn't mean that everybody considers themselves real gang sisters. there are people who are trying to enlist in the army such as scott gandy who is trying to enlist in the army and denied

enlisting in the army. there are people who have lost custody of their children because they listen to icp or they have an icp tee shirt on or they paint their faces once in a while. so this has really affected people this ridiculous ways. even myself, i could technically lose my law license because i could be considered gang affiliated or wearing gang apparel for wearing an icp tee shirt or listening to their music or going to a concert. >> i know some of the gang's concerts have been affected. what damages are you seeking from the justice department? >> we are not trying to why seek any compensation at all, we're just trying to stop the bleeding. people shouldn't be afraid to listen to music or like a certain art or genre of music. we are only seeking relief, to

be removed from the federal fbi gang list. >> ferris haddad. thank you for joining us. >> thank you very much antonio. >> let's check with janna. >> antonio, visas, have gone from 1,000 to 7,000 in a little country called naru, many are wondering why, rerouted to this island while trying to get to australia by boat. the detention center where they're held on the island paid for by australia has been called unsafe and inhumane by some australian politicians. to such an extreme amount, a spokes pern for the naru government said it would be for revenue purposes for what other reason would it be for?

one other tweeted, to keep the media off the island to keep the public in the dark on what's really going on. and the senator's opinion is echoed by many online. you can read @ajconsiderthis your application can still be turned down and the payment is nonrefundable. journalists can lose that amount by not even getting to the island. >> thank you janna, step away from the computer. why too much time in front of the screen could have you paying with your health. what the making of a presidential candidate is really like behind the scenes.

i'm phil tores. coming up this week on techknow. techknow's shini somara goes straight into the storm. winds of 150 miles per hour. but this twister is created in the lab. >> i'm at the national wind institute where they can actually recreate a tornado. >> now science and technology take on mother nature. >> who wins? >> it's completely fine. >> techknow. sunday 7:30 eastern on al jazeera america. >> excessive alcohol consumption contributes to 80,000 deaths a year. but is it the best and only solution to problem drinking? a growing movement suggests a one size fits all approach

advocated by aa is not the only solution. i'm joined by gabriel glazer, why women drink and how they can regain control. she also penned a recent editorial, titled why cold turkey seasonality the only route. really provoking stuff in your editorial and in your book. when you look at alcoholics anonymous, been around for 80 years. there isn't that much evidence that it is that successful. >> aa's own membership studies, show that any ten who begin, there are going to be five left. 80% of our rehab facilities use aa as their model. >> why has it become the model, the model that you always hear about, the model that's always on newspapers on television

shows on movies? >> exactly as you just said, because it's always on television shows and movies and that's what our medical system relies on even though it's not that effect -- even though it's ineffective, even though our legal system sends people into aa, and the narrative, to be lost and to be found is really something that makes a lot of sense to our nation, that has very christian mores. o, i can see that that person sinned, and now they're better because they found god. >> and actually the whole faith baysed side of it is an issue because it is an issue to some people who are alcoholics and who aren't believers. >> correct. and in nine states it's actually illegal, it's a violation to the first amendment to send someone to aa which courts do regardless. >> well then why have we focused so much on that one size fits all option when other countries around the world don't do that?

>> first of all our medical system our doctors are not trained in the new methodologies, our legal system is not trained in our new methodologies and in many other countries drugs are used. >> what are those new methodologies? >> those methodologies are cognitive behavioral therapy, they are teaching one self to moderate, seriously moderate and keep yourself accountable to the rationale you have chosen, look and see where they cross the line. and we are just not very comfortable with that as a nation. we seem to think okay, if you have a problem with drinking abstinence is best. >> is the only way. let's talk about drugs before we talk about moderation. why aren't we using them, because they are used in other places to some suck? >> they are available very

cheaply and pharmaceutical companies aren't making big bucks off of them. one drug is a drug called maltrexone, an opiood blocker, you feel relaxed you feel you a forric, it blocks the ability of the brain to feel that reward so if you take a drink after you've had maltrexone you don't feel the reward. it's like -- >> it makes it less attractive? spl exactly. >> let's talk about moderation. there's a whole program called moderation management that you can go online and it helps you to continue to drink but to control it so it's not a problem. >> absolutely. much in the way that weight watchers gives people the control to take over their eating habits. and moderation management is one methodology, it's an online,

free group that you can go to. nobody's making any money off that, either. there are autopsies that people can use -- there are apps that people can use. there's an app at moderatedrinking.com. there's another app that's just out by some florida researchers, it's available on itunes and the name of the producer is sobell, s-o-b-e-l-l. >> bud moderation doesn't work for everyone. one of the founders of mode ration management had a d.u.i. >> she left moderation management, said moderation is not working for me, i'm not one of the people for whom moderation works. i'm going to join alcoholics now anonymous and trying to abstain. it was two months later that she had that tragic accident having

joined aa. >> you have said that moderation isn't for everyone, people so alcohol addicted, that where do you draw the line for whom people alcohol is a problem and for people for whom it is a real problem? >> i think that's something that people have to think of themselves. we have a spectrum that is chawld are called alcohol abuse disorder. if you are on the mild to moderate end of that, you haven't had serious negative consequences as a result of your drinking, you haven't gotten fired, you haven't had a d.u.i., you haven't lost your kids, you're not firing off crazy rapid e-mails to your colleagues at night when you're loaded, then moderation is probably something that you might want to consider. a serious moderation program. obviously as you said if you are alcohol-dependent and you need a shot of vodka first thing in the

morning to steady your nerves, you're probably not a candidate. >> i know that this moderation issue requires abstaining for a month before going into this life. people should pay attention it is such a scourge for this country and women as you said are suffering the most for it and we are seeing more d.u.i.s in women. her book is how you gain control. all of us spend countless hours staring at our digital devices. just how bad sit for your eyes? a historic election >> we have 47% of our people who pay no income taxes... >> we take you behind the scenes >> i'm rick santorum, i'm running for president...

>> no barriers... >> i intend to be the nominee that defeats barack obama >> no restrictions... >> i think we're catching on... >> no filters... >> my guess is they won't be voting for me... >> al jazeera america presents caucus

>> today's data dive steps back from the computer. a new study coming out of the consumer electronics show finds long periods of time in front of any screen be i.t. a laptop, smartphone or tv is worse for your health than most people thought. division council found 70% of american adults can exhibit some

form of digital eye strain. that leads to not only irritated eyes and blurred vision but back neck and shoulder pain and headaches. the rate is higher among people 18 to 24 than those wearing glasses. the problem is not going away, especially since 2.3 billion smartphone, tablets and laptops were sold last year. blue light coming from digital screens can deal to macular degeneration and cataracts. no wonder a third of those polled spend more than ten hours in front of a screen every day and everybody surveyed spent at least three hours. some tips, wear special glasses to help focus. also for every 20 minutes you spend looking at a screen, take a 20 second break to look at something that's at least 20 feet away. please don't take that break until after our show. coming up, presidential

candidates in everyday life. surprising look into what it takes to run a campaign for president. the stream is uniquely the stream is uniquely

>> presidential politics are anything but slick in the early stages. the documentary caucus airing here on al jazeera america at sunday, 9:00 p.m. eastern, is the back stabbing of the iowa caucus. >> two candidates for any two months in a row. >> we will beat obama, and i'm here to tell you it's not even going to be close, won't even be close! ♪ [simultaneous speech] >> boy, it's just great to be out here in wisconsin. >> in wherever.

>> a.j. schnack is the director of caucus. i know you went out there to cover the caucuses, you had no particular focus on who your main characters would be, they end up michelle bachmann, and rick santorum, bachmann ended up hi and santorum low. >> santorum you always thought would be this kind of colorful character your best supporting character, so to speak, and he had the meteoric rise, nobody predicted him having. >> and you ended up portraying him in a way,. >> i didn't expect to see when he went there. he did drive around with a pickup truck with just one or two staff members going to small towns all the time meeting everyone he so. there is a line in the film that

he would talk and would sometimes outlast the questioners. it was a different way of politics than you usually see these days. >> do you think it's a good thing or a bad thing that retail politics in a mid western state ends up being so important for the whole presidential process? >> i thought it was a good thing. when i went to iowa i was under the impression that if you had a lot very little money meeting people answering their questions that you can have a chance i think is a great thing for our democracy. >> it is very interesting to see how that happened in iowa. you had a lot of access, you were around a lot so you caught all sorts of moments. what were the most awkward things you saw? >> the great thing being in iowa is they're really learning how to campaign. any day could seem, today is a great day, if you were mitt romney, someone could put a corn

dog in your hand, a vegetarian corn dog. if you are michel bachmann, your husband could rg threaten to arm wrestle someone. >> the person he was trying to thumb wrestle -- >> didn't end up having a bone in his thumb. that was the thing that was great about the early states. >> is it great, that if you don't flip the pork chops at the county fair properly or if you're in these situations where you have to be quick on your feet and you have no idea what's going to come at you from an audience that those things end up having a disproportionate effect on the race? >> any major office you are going to have crazy things thrown at you. i think the ability to sort of adapt to very different kinds of situations in iowa a lot of those things are small town fairs, situations you're probably not going to run into

in the oval office, but the ability to see how average americans are living and their concerns, that is important to our democracy. and it wouldn't work in states where would you have to spend a lot of money to even be competitive. >> it's good for the candidates to see things they wouldn't ordinarily see. >> i was there nine months, the candidates got much better about being candidates, talking about who they were and what they wanted as president. >> what surprised you the most? >> the fact that they were still going into these small ranches and coffee shops and trying oget people to listen to them. i covered the 2008, where you can't get anywhere near the candidates to see them really going in and begging for attention was really remarkable. >> right, at the smallest levels, a dozen or so people at times really individual politics. >> yes. >> how different were the candidates from their public personas or does this retail

politics really bring out who they are william. >> their public persona, a specific way how they are, or they have been type cast, seeing them with rounded edges was certainly remarkable. santorum was remarkable in the fact he was a guy who wore his heart on his sleeve. if you weigh annoyed, you would see how annoyed he was. you could see the boundless enthusiasm and the actual guy and that was independent kind of interesting. >> and you think smaller the campaign actually helped him because he was on time with things, managed to connect with people, whereas bachmann who won on the straw poll early went out with too much of an apparatus and weighed her down? >> her first stop on her first day of campaigning, she was told, whatever you do, don't be late. she would always be late for her

first appointment of the day. it would domino from there. people thought you're rushing in you're rushing out, you're not giving us the kind of time that we want to know who you are. >> only have about 20 seconds left. was there any favorite time in the time in iowa? >> rick santorum likes to eat, he went for a cinnamon roll and took the middle of the cinnamon roll and shook off the outside. >> as many of us like to do. >> while bachmann was talking. so no one saw it. >> best of luck with the documentary. caucus airs at 9 p.m. eastern. the show may be over but the story continues. you can also find us on twit @ajconsiderthis.
