vandalizing a nightclub, and he displayed psychotic behavior. >> it was shocking that he was able to get and retain a security clearance. >> reporter: but alexis retained the clearance because by regulation it was up to him to self-report his crimes to his superiors. otherwise, his clearance would not be automatically reevaluated until it expired after ten years. army specialist ricky elder is a similar case. after he got his clearance he was charged with two assaults, a dui hit-and-run and aggravated battery. it took five years to suspend his clearance after which, during a briefing, he killed his commander and himself. how do you assess the national security clearance process as it exists today? >> i think it's elaborate and woefully insufficient. >> reporter: former deputy secretary of defense john hamre says people with clearances should be monitored continuously for signs of mental illness or criminal behavior. once you're in you're in. >> once you're in you're in. we should be turning this thing upside down and saying what are the key jobs that are so sensitive that we're going to be monitoring these people intensively, continually. >> if you would like to see our full investigation, you can find it at cbsnews.com. click on "60 minutes." russia could be banned from the next summer olympics after the world anti-doping agency said today that russia is engaged in widespread sports doping at all levels. the report said the cheating is organized by the russian government itself. the anti-doping agency said that a moscow lab destroyed nearly 1,500 athlete test samples to keep them from investigators. and russian intelligence agents enforce the cheating. what we knew about blood pressure may be wrong. an important new study. and shamu's days as a performer are numbered. the "cbs overnight news" will be right back. today sea world announced its controversial killer whale show at its san diego park will be phased out. here's ben tracy. >> reporter: san diego is saying so long to the shamu show. sea world says by 2017 it will replace the theatrical killer whale show with what it calls a more natural experience with a conservation message. ceo joel manby gave few details while making the announcement on a call with investors. >> we start everything by listening to our guests and evolving our shows to what we're hearing. >> something's wrong. >> reporter: what they're hearing has not been good. sea world has been under fire since the documentary "blackfish" was released in 2013. it criticized the company's treatment of its orcas and chronicled the whales' violent attacks on their trainers. in 2010 dawn brancheau was killed when one of the whales pulled her into the water and tore her apart. attendance has been falling, and the company has lost half its market value in the past two years. former sea world trainer john hargrove. >> people can be inspired and not have to see a caged animal that has given up their life for you to be entertained. we've just moved past that. >> reporter: last month the california coastal commission barred the park from breeding orcas. california congressman adam schiff plans to introduce legislation to ban breeding of captive orcas nationwide, which would impact sea world's other parks. >> i view the step taken by sea world today as small but positive. but it really needs to go much further. we really need to end the captivity of these majestic creatures. >> reporter: now, sea world is only ending the killer whale show at its park in san diego. scott, the company says the shows will continue at their parks in orlando and san antonio, texas. >> ben tracy, thanks. important health news when we come back. tonight we have results of a new study that says sharply lower blood pressure leads to significantly longer lives. we asked our dr. jon lapook to explain. >> reporter: current guidelines for people with high blood pressure generally target a level of below 140, for those age 60 and over below 150. this trial followed more than 9,000 people over 50 with high blood pressure and at least one other risk factor for heart disease. doctors used medication to lower their pressure to under either 140 or 120. in august the study was ended early when data showed a clear difference in outcomes. results published today show the under 120 group had a 38% lower risk of heart failure than the other group and a 27% lower risk of death. however, the under 120 group also had more serious side effects, like low blood pressure, fainting, abnormal blood chemistries and kidney problems. dr. george bakris of university of chicago medicine specializes in treating high blood pressure. >> in these people that are older you can push the blood pressure down to 120. it is well tolerated, and there is a benefit. >> so jon, what are doctors likely to do with this information? >> well, scott, doctors tend to be cautious. while the more aggressive treatment does lower the risk of those heart problems, it can increase the risk of those other side effects we talked about. so i think we're going to see an ongoing discussion of the pros and the cons. >> jon, thanks very much. well, there was plenty to talk about about what happened in meridian, mississippi on saturday night as folks ate inside an ihop the parking lot was gobbling up their cars and trucks. 14 in all. the sinkhole is 30 feet wide, 360 feet long. no one hurt. 211 years after dying in a , alexander hamilton and hip-hop might seem like an unlikely pair, but the combination is the hottest ticket on broadway. $57 million in advance sales and counting. lin-manuel miranda is the playwright and the composer, and he also plays the main character in hamilton. charlie rose sat down with him for "60 minutes." >> this is what i knew from high school. i knew hamilton died in a duel with the vice president. i knew he was on the $10 bill. but really i just was browsing the biography section. it could have been truman. >> and as you read it, what happened? >> i was thunderstruck. i got to the part where, you know, a hurricane destroys st. croix where hamilton is living and he writes a poem about the carnage and this poem gets him off the island. >> you saw a rap artist in him. >> yes. i drew a direct line between hamilton's writing his way out of his circumstances and the rappers i'd grown up adoring. >> reporter: miranda's gift is making that story come alive. >> are you ready for a cabinet meeting, huh?

>> it's not firmly on the path to democracy. we are on the path to disciplined democracy. >> what is disciplined democracy? >> i think it's democracy as seen by military authoritarian leaders. >> does it fit with your idea of democracy? >> not an exact fit, no. >> reporter: to reach su-shi we traveled five hours by road from rangoon deep into the heart of burma. there are about 50 million burmese. this is how most of them live. our destination was this extravagant city the generals carved out of the jungle. 40 times bigger than washington, d.c. it's called napidao, burmese for seat of the king. they moved the capital here from rangoon a decade ago. it was built in secrecy and no one would tell us how much it would cost. it has an orwellian feel with grandiose buildings, deserted ten-lane highways, and most bizarre, almost no people. this place is for rulers, not citizens. and it's not a place su shi feels comfortable. she's here because she's a member of parliament. when you look at this and the power it represents, what makes you think you can change this? >> it does not present itself as part of the country, as part of the people. and however impressive this complex may be, it doesn't really represent the people. >> reporter: when we met aung san suu kyi she seemed calm, almost serene, but after talking with her for a while we noticed the steely determination that got her through nearly two decades of house arrest. you're a tough-minded person, aren't you? >> i never thought of myself as being particularly brave. i used to be frightened of the dark when i was small. and i'm not very good with dead rats and things like that. but face what has to be faced. and i hope as best as i'm able. >> you must know that you are seen worldwide as a symbol of democracy. >> no, i don't like to be called a symbol, and i don't like to be called an icon. i will just say that i have to work very, very hard. so i'd rather be known as a hard worker. i don't think symbols do much, nor icons. >> reporter: suu kyi caught the world as tension when she first tried to bring democracy to burma in 1988. the generals crushed her movement, killed and imprisoned pher followers, and put her undr house arrest. after a nationwide revolt led by monks called the saffron revolution the generals finally released suu kyi in 2010. within two years she'd won a seat in parliament. she's now campaigning hard for her pro-democracy party to win control of parliament in next month's elections. you've got elections coming up. important elections. do you believe they will be free and fair? >> i don't think believing is what we need now. what we need now is to work as hard as possible to make sure they're free and fair. this is a time of challenges, and challenges mean opportunities as well. >> reporter: one opportunity she likely won't have is to become president. her party is expected to win a big majority. but the generals wrote the constitution, and they stuck in a clause that prohibits anyone with foreign-born family from becoming president. suu kyi's two sons are british subjects. so was her late husband. >> do you think that constitution is written specifically for you to keep you from being president? >> i dare to say publicly and openly that that particular clause is written with me in mind. >> would you like to be president? >> what i would like is for our people to feel that we have actually won through, that the struggle for democracy has been crowned, and if the people are allowed to choose freely their head of government and choose to choose me, that's fine. >> reporter: whoever rules burma will have to deal with this, a violent conflict between buddhists and a muslim minority called the rohingya. the government doesn't consider them citizens. three years ago buddhist mobs torched rohingya villages when muslim men were accused of raping a buddhist woman. more than 120,000 ethnic muslims fled to government-controlled refugee camps. international human rights workers say they're more like concentration camps. some aid workers have called this ethnic cleansing. the camps are usually off limits to outsiders. but our team managed to slip in. we found desperate people with little food, less health care. there is no lack of fear. abdu salem fled the buddhist mobs with his wife and daughters. the mob and the monks chased them, he tells us, beating and killing them. many children died, including one of his daughters. with misery inside the camps and buddhist mobs outside, thousands of rohingya have crowded onto rickety boats to escape to neighboring countries by sea. most have been turned back, detained, or ended up in camps again. >> you can see more of bill whitaker's report on burma at cbsnews.com. the overnight news will be right back. the republican presidential hopefuls gather again this evening for the latest in their series of prime time debates. the field is getting smaller as several candidates watch their poll numbers drop. front-runners donald trump and ben carson will be center stage, surrounded by john kasich, jeb bush, marco rubio, ted cruz, carly fiorina, and rand paul. four others, rick santorum, chris christie, mike huckabee, and bobby jindal, will debate earlier in the evening. meanwhile, lindsey graham and george pataki didn't make the cut. on saturday cbs news will be hosting the democratic presidential debate from des moines, iowa. it's another chance for bernie sanders to try and cut into the lead of hillary clinton. jim axelrod spent some time with sanders for sunday morning. >> before you said it i said don't underestimate bernie sanders. >> hi. >> best of luck. >> thank you very much. >> how are you doing? >> thank you, sir. thank you for running. >> thank you. >> does this feel good? >> of course it feels good. it feels great. ♪ and bernie sanders said to me you shouldn't vote for hillary ♪ >> reporter: the striking thing about bernie sanders is not that he's a man whose time has come. >> bernie, thank you so much. >> i'm bernie sanders. i'm running for congress. >> i know. >> reporter: it's that he's been waiting so long. >> i love to hear you talk on tv. >> thank you! >> reporter: for his time to get here. >> we do two a minute we're doing well. >> you have the wealth in this nation to provide a decent standard of living for all of our people. >> demand pay equity for women workers.

>> yeah. >> were you waiting for america to catch up with you? >> well, i'm glad that it's happened. >> please welcome senator bernie sanders. ♪ >> reporter: after 40 years of trying to gain traction with his message sanders, the 74-year-old democratic socialist senator and former mayor of burlington, vermont is suddenly dancing with ellen. >> i don't have a super pac. i don't even have a backpack. i carry my stuff around loose in my arms like a professor. >> reporter: he's being parodied by dead ringer larry david. >> i own one pair of underwear. that's it. some of these billionaires, they got three, four pairs. >> were you watching "saturday night live"? >> i like seeing it. >> who told you this is -- >> who didn't tell me? i heard from 20 different people. >> did you laugh? >> yeah. very funny. >> berniesanders.com. check it out. it's a mess! >> and he's running neck and neck with hillary clinton in new hampshire by calling for a revolution. >> the only way we really transform america and do the things that the middle class and working class desperately need is through a political revolution. >> political revolution. that's a big term. >> look, in the last election, jim, 63% of the american people didn't vote. 80% of young people didn't vote. big money is increasingly buying political elections. a political revolution means that we involve tens of millions of people in the political process today to stand up and fight for their rights to stop the disappearance of the american middle class and say that our government belongs to all of us and not just a handful of wealthy campaign contributors. >> i'm just wondering if you're misreading what it is american people want. >> no, i'm not. you check out the polls. >> i know how much you love conventional wisdom. now here we are and it looks like you got a little more traction than the experts thought you would. >> yes. >> why? >> because you and the punditry and the corporate media have a view of the world which i think is very out of touch with what the american people are feeling. >> you really don't like us. >> no, no. it's not a question of not liking you. i like you. you're a very nice guy. what corporate media is about is very often deflecting attention from the most significant issues facing our country and giving us entertainment all the time. and i get upset that media by and large is more interested in dumb things that somebody says or how much money i'm raising. nobody cares about that. we've got to focus on the real issues facing america. >> how are you doing? >> reporter: if sanders is the junior senator from vermont, his matter-of-fact style is all brooklyn, where he was born and raised among working-class immigrants, many of them jews like himself whose families had fled discrimination in europe. >> economic inequality, it's your reason for being. and i'm wondering where that -- >> i will tell you where that came from. when you're 5 or 6 years old and you hear your parents arguing, sometimes pretty fiercely, it's very disturbing to a child. and my parents did. >> over money. >> over money. almost always. my father came to this country from poland at the age of 17 without a nickel in his pocket. he always had a job and he never made a lot of money. so we were never poor, but we just never had a whole lot of money. i think we were solidly lower middle class. >> but you could have then said you know, what i'm going to go to medical school and made money. >> yeah, i guess. >> but you didn't. >> no, i didn't. i think from an early age -- and again, what i cannot tell you -- you asked a fair question, i just don't know the answer. why we turn out the way we do. >> reporter: it is the rare politician who will admit he doesn't have all the answers. but uncommon has long been one of the more polite descriptions of sanders. after all, how many candidates have disclosed they have five-figure credit card debt? >> you have to become an open book in a way you've never been before. for instance, between $25,000 and $65,000 in credit card debt. >> my wife handles that. i think actually that's been paid. look, we do fine financially. a united states senator makes a good living. >> how do you get that much credit card debt? >> i actually don't know. you have to other ask my wife that. but i think we have paid it all off. >> do you think in some way that makes you more relatable to the average american? >> maybe. but that wasn't the intention, i'm sure. >> he's been with his second wife jane -- >> the pitch is a little on the inside. >> reporter: -- for 34 years. >> thank you. >> reporter: they have seven grandchildren between the two of them. >> whoa! >> you knew going into this -- >> so quickly. >> whoa! unbelievable. >> i said to him when we were talking about whether he should run, isn't there another way you could get the issues out? >> this is the ultimate i told you so moment in marriage. >> it is. >> reporter: as jane sanders knows better than anyone, her husband is always going to do it his way. >> he's not really into the statecraft. we do try to point it out now and then that he needs to pay attention. >> but he fights you every step of the way? >> oh, yeah. he is all policy stuff. >> how many of you guys are looking forward to going to college? how many are worried about the cost of college? >> reporter: as this campaign evolves the extent to which you need not to change your message but to change the delivery mechanism so that it's not eat your peas -- >> i understand. >> do you run the risk of being too serious? >> you hate the question. >> no. it's a fair question. i know how to do this stuff. how you doing? i'll tell you a few jokes and i know you're too dumb to want to listen to a speech beyond three minutes so i'm going to be brief. vote for me, i'm great, everybody else is terrible, have a nice day. i don't do that. >> if we stand together there is nothing that we cannot accomplish, and that is exactly what this campaign is about. >> can't be politics as usual. i ain't a candidate of the politics as usual. >> reporter: with hillary clinton starting to expand her lead in polls nationwide, the stakes are growing ever higher. as bernie sanders prepares for the democratic debate cbs news will host this saturday. >> you are not running just to get a good speaking slot at the democratic national convention. >> no. we are running to win. i fully admit we are the underdog. we started this campaign at 3%, 5% in the polls. nobody thought that we could win in new hampshire, win in iowa. and yet we're doing well in both of those states and we're doing well around the country. so we're in this race to win it. >> bernie sanders! ♪ the "cbs overnight news" will be right back. it's a highly thercontagious disease.here. it can be especially serious- even fatal to infants. unfortunately, many people who spread it may not know they have it. it's called whooping cough. and the cdc recommends everyone, including those around babies, make sure their whooping cough vaccination is up to date. understand the danger your new grandchild faces. talk to your doctor or pharmacist about you and your family getting a whooping cough vaccination today. well, things in the bedroom have alwaysyeah, no complaints. we've always had a lot of fun, but i wanted to try something new. and i'm into that. so we're using k-y love. it's a pleasure gel that magnifies both of our sensations. right, i mean, for both of us, just... yeah, it just takes all those awesome feelings you usually feel and it just makes them... rawr... dare to feel more with new k-y love. on friday an auction house in new york city will raise the gavel on one of the most unique collections ever sold. it includes some of the finest tattoo art from around the world. michelle miller has a preview. >> reporter: often misunderstood, tattoos have been used as cultural traditions all over the world. brought stateside by swells of servicemen post-world war ii, they came to signify rebellion, a badge of courage, and everything in between. >> when i came up, the only people who wore tattoos were people who lived on the other side of the tracks or in the navy. >> reporter: now they're getting the attention of sophisticated art dealers and auction executives like arlen ettinger, president of guernsey's auction house. >> i really wasn't familiar with the notion of tattoo art on anything other than the body. when i went to view the material for the first time, i saw a nice coffee table-looking book featuring the work of one artist. >> reporter: that artist was the famous horioshi iii. ettinger then called his office and asked for a copy. >> and they called me back and said, well, which one do you want?
