industry has cut more than 275,000 jobs. since oil prices peaked at over $100 a barrel in mid 2014. why? for starters, demand for oil fell. in the past, opec has cut production in response. not this time. >> before the oil price collapse, the assumption is that opec would cut production. but the key oil producers in the gulf, saudi arabia and the other gulf states, said we're not going to cut unless other people cut. >> reporter: daniel yergen is vice chairman of ihs, an international information company. and the pulitzer prize winning author of "the prize, a history of oil." >> saudi arabia's basic strategy is to maintain its market share in the global oil market, and that's been the starting point for them. >> reporter: at the expense of everybody else?

>> reporter: so began a huge game of chicken. with saudi arabia and its opec partners pumping full blast. russia, too. and the united states. you've heard of fracking? pumping water into shale formations to free hard-to-get at oil and gas. well, fracking meant that the united states suddenly was producing a lot more oil. so much that for the first time in 40 years, we're exporting it. >> u.s. oil production went from 5 million barrels a day in 2008 to 9.7 million barrels a day in april of 2015. in other words, u.s. oil production almost doubled in a matter of just a few years. >> reporter: during the good years, midland and odessa, texas turned into boom towns. same story in williston, north

based on $100 a barrel oil, entrepreneurs borrowed billions of dollars to buy into the bonanza. workers flocked to the oil patch. >> i heard about all this big money. so i thought i could get a little piece of that pie, i suppose. >> reporter: so many they had to live in trailer camps. on cots in church halls. then the price crashed, thanks in large part to china's slowing economy. meanwhile, every day the world is producing something like a million and a half more barrels of oil than it needs. there's an ocean of it out there. in massive storage tanks. and right now, at least 100 million barrels are sitting in tankers, parked at sea. mike rasco just wants to hang on to his home. he never lived lavishly, even

cbs sunday when the denver broncos take the field against the carolina panthers. the mile high city in charlotte, north carolina are two very different places. but which is more super? we sent john blackstone and michelle miller to find out. >> last time denver was in the super bowl aheaded to seattle to tour that city. get what? the seahawks won. so this time i'm here to offer a little leverage and to let you know, michelle -- >> let me know, john. >> that denver is a city that will always be on top. >> that is well and good, john, but panther pride runs deep in the south. and though no city can lay claim to this team that's headed to the super bowl, charlotte, which is where the city is based, has been working on a victory all its own. >> okay. >> keep pounding.

carolina fans, but it's also become the mantra of the city of charlotte. among the fastest growing cities in the south. >> sorry if i'm looking down on you, michelle, but denver is the mile high city. and talk about growth, about a thousand people a week are moving here. and it's the number one choice for millennials on the move. >> if you're planning to move in a new sofa for your big super bowl watch party, consider this -- 60% of all american furniture in homes originate in north carolina. >> yeah, that's nice, michelle. but not a whole lot of sitting here in denver, when it's sunny about 300 days a year, people are outdoors. that may be why denver is among america's fittest cities. >> john, have you even tried the barbecue here in north carolina? charlotte mayor jennifer roberts has. >> and we're here at spoon's

>> if you're craving a cheese berger, this american favorite was originally created right here in denver. i understand you have a bit of a wager going on with the mayor of charlotte. >> after the broncos win super bowl 50, mayor roberts will have to wear this peyton manning jersey in public. in fact, you might as well take it now. >> let's hope peyton manning doesn't throw like that. >> let's hope he does. i'm not going to wear a broncos jersey. you're going to be wearing a cam newton jersey and some lovely cam newton socks are going to look wonderful on you when the broncos lose. >> nice shins. cheese burgers? want to burn off some of those calories on a golf course, no better place than the carolinas where north and south carolina are among the top ten places to play. and here at quail hollow club,

championship. ahh! >> that's good to know, michelle, but colorado is in the top ten, too. and because of the altitude, the air is thinner here, your ball will go 10% further. >> you want to talk altitude? let's talk about the wright brothers who launched the age of aviation from the carolina coast. >> well, there are plenty of historical places here in downtown denver, like union station, which has recently -- what's that noise? >> oh, i'm sorry, john. is this bothering you? it's so addictive, this bubble wrap. the company that makes it, right here in north carolina. >> bubble wrap? here in denver, you could pop into a marijuana dispensary. since pot was legalized here in 2012, it's become a billion dollar business. >> marijuana is not legal here in the carolinas, not even for

but moon shine is. what is this called? >> mvp punch. >> mmm. well, before prohibition, the bootleggers used to tote this stuff around and they came up with another carolina tradition -- nascar. >> here we go! whew-hoo! hey, richard petty. >> how are we doingsome >> you've been around this track a few times. how did it go? >> a little slow to begin with, but a little more practice. >> need to spend some more time in carolina. >> no nascar here, initial, but there's beer. >> cheers. >> thanks, jason. denver brews more beer than any other city in the country, including about 100 craft breweries like this one. and bear with me, michelle, while i tell you that colorado

ranked number one by the national endowment for the arts. who wouldn't want to come see a show here in red rocks? it's a perfect sunday morning in my quiet little mountain town >> and we can also thank denver for "south park." >> but here in north carolina, it's a real place. and let's not forget the state also is home to one of the very first public universities. unc. and it's tobacco road rival, duke. which is the alma mater of our own charlie rose. he still has a home here in henderson, where he grew up. and really, isn't that all that matters?

>> well, whether it's the broncos or the panthers who come out on top on sunday, the real winning city will be right here in san francisco. it's proved a remarkable host and it's a place i'm proud to call home.

sunday's super bowl will be played in levi stadium outside of san francisco. it's the newest stadium but still needs a little work. jeff glor has the story from super bowl city. >> reporter: super bowl city is sort of the center of activity here in san francisco, the old candle stick park has been torn down. the new 49ers home was opened two years ago, and not everything has worked out as planned. for $1.3 billion, you would expect levi stadium to be a

but on the field, frustration. not just over a lackluster 49ers season. in october, the natural turf partially collapsed under the foot of justin tucker. >> he fell on the turf, and they've had trouble on the turf here. >> reporter: so for weeks before the super bowl, more than 600 tuns of new sod were brought in. ed works for the nfl, not the 49ers. and he does this every year. every postseason, the cite of the super bowl gets a brand new field. the grass is designed to withstand not just the players -- >> caught, touchdown. >> reporter: but the wear and tear what's become a massive mid game operation. the halftime show. >> this is baby and spoon fed every single day. it's a living, breathing, growing entity and you can't turn your back on it.

had its issues. are those over? >> the 49ers did a great job handling that. new stadium, everything is new in here. you work out the bugs. >> reporter: the other part of the structure that's gotten so much attention -- the technology. >> stadium in and of itself came ready to go. most stadiums have to work to be ready for a super bowl. >> reporter: because it's new and it's in silicon valley. >> yes, both. >> reporter: there are more than 400 miles of fiber and copper cable, supporting 40 times the band width of typical stadiums, allowing fans to call, text, tweet, and watch instant replays from their phones at will. now on sunday, if the green can match the gadgets, the league is hoping for a pitch perfect experience. we will see how the field holds up. one positive, there was some concern about el nino and a potential soggy sunday. the forecast looks clear and sunny. >> and that's the "overnight news" for this friday. for some of you, the news continues.

later for the morning news and "cbs this morning." from the broadcast center in new york city, i'm anna warner. a new health emergency has been declared in another big florida county, as concern grows that the zika virus can now be spread through blood transfusions. also tonight, trump looking for a new hampshire comeback. >> it's called crunch time, right? the smirk that irked members of congress. >> i know you're smiling, but i'm very serious, sir. and a sunday kind of love between women and the nfl. >> there's just something about football. it always keeps you on your toes.

news." a health emergency was declared in a fifth florida county because of zika virus, which is suspected of causing birth defects. broward county includes fort lauderdale. florida is reporting at least 12 cases, but in all more than 51 people have been infected in 12 states and the district of columbia. conditions in the sunshine state are especially conducive to zika. mark strassmann is there. >> reporter: zika anxiety pushed teams of mosquito-control sprayers into miami-dade neighborhoods today. florida's hot, humid client puts its 20 million residents at risk for the virus along with millions more tourists. governor rick scott. >> we're a state that has mosquitoes similar to mosquitoes that could carry this, so it's better to get ahead of this. >> reporter: scott has asked the centers for disease control, or

kits here. the state will buy 4,000 more. testing would focus on pregnant women who are especially vulnerable. the virus has been linked to a birth defect called microcephaly. babies are born with abnormally small heads and brains. there is no zika vaccine, and no antidote. dr. walter tabachnick, an expert on infectious diseases. >> i think we have to take this so seriously that we must do everything possible to reduce the chances of getting zika. >> reporter: floridians often live with standing water where mosquitoes breed, but residents are being urged to get rid of it, inside in flower vases and water tanks, and outdoors in empty pails, clogged gutters or wherever water pools. the cdc has advised pregnant women to postpone traveling to 30 countries and territories, including mexico. >> so, i'm 16 weeks pregnant. >> reporter: erica benstock declared her own state of

she has canceled her trip next month to cancun, where she was supposed to be matron of honor in her sister's wedding. >> now that it's in the state of florida, how far is it going to spread and what does that mean for everybody who isn't traveling? >> reporter: because you could stay home -- >> and still get it. >> reporter: 80% of zika patients show no symptoms. scott, it's likely there are many more cases than the official numbers indicate. >> mark strassmann in tampa tonight. mark, thank you. the cdc says zika is spreading in these 26 countries and territories in the americas. in addition to mosquitoes, it's transmitted through sex, and we learned today, blood transfusions. dr. jon lapook has been reporting all week from ground zero of the outbreak in brazil. >> reporter: here in brazil, donated blood is not yet tested for zika virus. instead, donors are asked if they've recently been ill, but since 80% of people with the

reporting misses most infections. in brazil, the virus is predominantly spread through mosquitoes, but in the united states, nearly all the reported cases are imported from travelers. that's why the major blood banks say people should not donate blood if they have traveled in the last 28 days to mexico, the caribbean, south or central america. dr. darrell triulzi, the director of transfusion medicine at upmc. >> the deferral will take care of the great majority of the risk, so i think by far the benefits of transfusion would outweigh the very small risks of an infected unit. >> reporter: there is a test called pcr that can detect zika virus in the blood, but it's not government approved in brazil or in the united states, where about 21 million units are transfused each year. >> we keep the virus here frozen. >> reporter: researcher rafael franka has been studying zika closely for the past year at this laboratory in brazil.

technology and people to do that. we need to make sure we have solid results. >> reporter: so there's nothing really stopping you from testing every blood transfusion for the presence of zika virus? >> yeah, true. we just don't have enough time actually. >> reporter: if mosquitoes in the u.s. get infected, travel history alone would not be an effective screening method. if that happens, scott, the chief medical officer for america's blood center says testing donor blood for the presence of zika virus would be considered. jon lapook in brazil for us tonight. john, thank you. today, in the water emergency in flint, michigan, the epa said lead levels are dropping and home filters appear to be working. but that isn't true everywhere, as our adriana diaz discovered. >> we have this information sheet from the epa. >> reporter: epa agents have fanned out in flint, targeting homes where lead levels remain

city's second highest amount of lead on record. it's classified as toxic waste. >> does it look like that water is contaminated? >> that looks like regular water? >> right. only to find out you got over 5,000 -- >> reporter: parts per billion. >> parts per billion. so this is the reason why we never really even considered our water being bad. >> reporter: old and corroded lead pipes in some homes are still releasing lead into the drinking water. since january 1st, 364 homes of the more than 5,000 tested exceeded the federal lead limit of 15 parts per billion. 48 topped 150 ppbs. mark is leading the epa's effort in flint. overall is water safer here for flint residents? >> safer since last fall? >> reporter: uh-huh? >> we don't have the data to be able to say that yet. so we're hoping, but again, that's why we're here. we're collecting samples.

health of the system. >> reporter: concern for lead levels in children's blood is still high. today state health officials released the latest data. they show 2.5% of children have elevated blood lead levels. last year at this time it was 2.1%. parents continue to bring their children in for blood testing, fearing developmental delays and behavioral issues. >> it's just a bad situation. we just worry. >> reporter: 34 members of the epa are on the ground conducting tests at homes with the highest lead levels. scott, today officials announced they want every child in flint under six years old tested for lead by april 1st. >> adriana diaz. adriana, thanks. well, there was quite a scene on capitol hill today. martin shkreli was there, the former drug company executive who became a poster boy for price gouging and was later arrested on unrelated fraud charges.

drug prices. >> on the advice of counsel, i invoke my fifth amendment privilege. i invoke my fifth amendment privilege. i invoke my fifth amendment privilege against self- incrimination and respectfully decline to answer your question.

there's just four days until new hampshire holds the first in the nation primary. and a new poll shows bernie sanders and donald trump with commanding leads. for the democrats, it's sanders over hillary clinton 58% to 36%. gap slightly over the last few days. the candidates held a debate last night in new hampshire. here's some of what they had to say. >> it is just not achievable. let's go down a path where we can actually tell people what we will do.

that's what i intend to do. >> senator sanders, you spent nearly two decades in congress and haven't gotten any of these things past. why do you think as president you'll be able to achieve big, new programs? >> i haven't quite run for president before. [ applause ] let's deal with some of the comments that secretary clinton made. and by the way, you know, sometimes there's a lot of drama here. i've known secretary clinton for 25 years and respect her very much. here is the issue. every major country on earth, whether it's the uk, whether it's france, whether it's canada, has managed to provide health care to all people as a right and they are spending significantly less per capita on health care than we are. so i do not accept the belief

america can't do that. i do not accept the belief that the united states of america and our government can't stand up to the rip-offs of the pharmaceutical industry, which charge us by far the highest prices in the world for prescription drugs. number two, in the economy today, everybody understands that we need a well-educated workforce. this is 2016. when we talk about public education, it can no longer be k through 12th grade. i do believe that public colleges and universities should be tuition free. well, how do we pay for that? it's an expensive proposition. i do believe we should substantially lower student debt in this country. which is crushing millions of people. we pay for it by a tax on wall street speculation. the middle class bailed out wall street in their time of need. now it is wall street's time to help the middle class. >> a poll out this evening shows

by 11 points. that's a seven-point improvement for rubio, putting him ahead of ted cruz. trump is looking for a comeback and major garrett is there. >> reporter: donald trump is learning retail politics means more than selling hats and t-shirts. >> okay, let's go. >> we love you. >> reporter: it means mingling with voters, something trump rarely did in iowa. >> got to do it. it's called crunch time. >> reporter: crunch time is right and trump's ad hoc ground game is playing catchup. he's led every poll here since july, but today would not predict victory. >> i don't think in terms of losing. that's why i'm here right now. i think we're going to do well. >> donald trump is very rattled right now. he told the entire world he was going to win iowa. and then he didn't win. >> reporter: iowa caucus winner ted cruz is trying to maximize momentum to catch trump and beat

rubio picked up rick santorum's endorsement yesterday. but this morning santorum did little to help the florida senator. >> list one accomplishment that marco rubio has achieved in four years in the united states senate. it doesn't even have to be a passed bill. >> the bottom line is, there isn't a lot of accomplishments and i don't think it's a fair question. >> reporter: rubio down played santorum's comments. >> i wouldn't expect him to be familiar with my record. >> we're electing a president of the united states. not a back bench tore the united states senate. >> reporter: jeb bush has made an issue of rubio's lack of experience all week. today the super pac supporting bush released its first tv ad featuring former president george bush. >> i know jeb. i know his good heart and strong backbone. >> reporter: scott, top republicans here say trump can win without the organization that ted cruz, john kasich and jeb bush have devoted to new

>> major garrett for us in new hampshire. thank you. speaking of jeb bush, he finished sixth in iowa, and he's at 10% in new hampshire. well, today, norah o'donnell spoke to him and his mother, former first lady barbara bush. >> just a few years ago you said no more bushes in the white house. >> funny. i knew you were going to bring that up. and i said it because it is such a sacrifice for his family, but now i know he is so needed that he has to run. >> you can see more of norah's interview with jeb and barbara bush tomorrow on "cbs this morning." hillary clinton's campaign has been facing questions about her decision as secretary of state to use an unsecured computer server in her home for official e-mails. some of those e-mails turned out to contain top-secret information. well, today we learned that clinton is not alone, and we asked nancy cordes to look into

>> i will be a better president. >> reporter: clinton suddenly finds herself in good company. according to an internal state department review, two of former secretary colin powell's personal e-mails also contained classified information, as did ten e-mails from the personal accounts of top aides to his successor, condoleezza rice. >> most of them i think are pretty benign. >> reporter: like clinton, powell exclusively used a personal account as secretary of state, though he e-mailed far less often. in a statement today he said the the two e-mails in question were -- the clinton campaign happily sided with him. press secretary brian fallon. >> this is an example of over- classification run amok. >> reporter: the state department announced last week that 22 of clinton's e-mails which sat on her private server for years are being reclassified

highest levels of classification, higher than the secret and confidential designations given to the powell and rice e-mails. more than 1,500 clinton e-mails have already been put in those categories. isn't there a big difference between an e-mail or two being classified as confidential and 22 e-mails being classified as top secret? >> these e-mails that have been judged top secret are completely wrong. we want them released. let the public see them. >> reporter: the fbi is still looking into clinton's use of a private server, but, scott, the clinton campaign views this as a rare positive development in a year-long controversy. >> nancy cordes with the clinton campaign. nancy, thank you.

today several hundred people paid final respects to 13-year-old nicole lovell of blacksburg, virginia. there was a hearing today for one of two virginia tech students who are charged in her stabbing, and don dahler is following the case. >> reporter: natalie keepers' parents left the montgomery county courthouse after a judge denied their 19-year-old daughter's bail, and the prosecutor, mary pettitt, laid out new details of the case against her. pettitt described how keepers and fellow virginia tech student david eisenhauer carefully planned the murder of 13-year- old nicole lovell, whom he met online. police found messages from him

the prosecutor said the college students plotted her murde at fast-food restaurant. they then bought cleaning supplies at one walmart store and a shovel at another. investigators say the girl was murdered january 27th, the same day she climbed out of her bedroom window to meet eisenhauer. she was killed on a remote road north of virginia tech. the prosecutor said that after the girl was dead, the two put her body into the trunk of eisenhauer's lexus and drove to north carolina where they dumped it by the side of a road. pettitt said keepers confessed to her role in the girl's death. prosecutors did not reveal a motive but said keepers was excited to be part of something special with eisenhauer. scott, keepers' parents told the court that she has mental health issues. >> don dahler, thanks. still ahead, quarterback cam newton, the super bowl star,

super bowl 50 is sunday on cbs. our special correspondent and super bowl pregame host james brown sat down with panthers' quarterback cam newton for "60 minutes sports." >> reporter: other north carolina athletes that you have a relationship with, those with north carolina roots, michael jordan, stephen curry and others like lebron james, what one something did you take away from those relationships?

single time i see michael jordan. and steph curry is a person that has really embarked upon elite status in nba history. and i'm not too proud to ask from lebron to, you know, michael jordan, to steph curry or even yourself that i need help. you know what i'm saying? i'm not perfect. anything that you can tell me, anything that anyone else can tell me that may help me in my growth, i want to hear it. >> reporter: when they signed you to that contract, they said it was because they felt you could get them to the promised land. you're like moses now. you're at the doorstep. will you be joshua and take them into the promised land is the question? >> i'm hoping. i'm hoping. i can't promise anything. i can tell you this, there's going to be a person out there on super bowl sunday prepared

super bowl city in san francisco. i wonder, cam newton gets a lot of flack for his celebrating after touchdowns. what does he make of that? >> you know, scott, he's quite puzzled by the extent of the reaction to his celebrations on the field. it is atypical for a quarterback to be quite so demonstrative, but he'll be first to tell you, enthusiasm is what has gotten him to this point. as a matter of fact, my high school coach says nothing great is every accomplished without enthusiasm. he's embracing it. they're at the doorstep of a super bowl championship. >> well, a lot of enthusiasm for the game this weekend. james brown, thank you very much. and you can see j.b.'s full interview with cam newton on "60 minutes sports." that's tuesday night on showtime. well, if you were anywhere near a dance floor in the '70s and '80s you know the music of maurice white. do you remember >> he was the founder and leader

their mix of soul, jazz, funk and disco sold more than 90 million albums and won a grammy for white's "got to get you into my life." maurice white has died of parkinson's disease. he was 74.

today nfl commissioner roger goodell said the league will now require teams and his own office to interview women for executive positions. there are already a lot more women among the fans, including michelle miller. >> reporter: for the past ten years, megan lopresti and her friends have been meeting up every sunday for one reason. >> i like sports, but there's something about football.

>> reporter: lopresti is part of the 43% of the nfl fan base that's woman. and it's not just the fans. >> we'll start with the latest hire, kathryn smith. >> reporter: last month the buffalo bills made history in hiring the first full-time female coach. >> how do you get something going offensively? >> reporter: tracy wilson is the lead sideline reporter for cbs sports. women never get a chance to play football. you just watch it from afar. >> reporter: she's loved football ever since she wore pigtails. when did women say, hey, i want in? >> that's a good question. i think nfl has made a big push, whether it's breast cancer awareness month, what they sell in the stores of tailored jerseys, the commercials you see on tv. you don't own me >> reporter: madison avenue is taking note. last year 54 million women watched the super bowl. >> finally nfl women's apparel fit for you.

wife of jets' owner woody johnson, is a fashion ambassador for the nfl, where women's merchandise is the fastest growing sector with sales increasing more than 20% a year. what do women bring to the sport that men don't? >> the woman is the glue that holds the whole family together. the woman makes most of the decisions. and that includes purchasing power. >> reporter: so while the men may score the winning touchdown this super bowl sunday, women are fast becoming football's most valuable players. michelle miller, cbs news, san francisco. and that's the "overnight news" for this friday. for some of you, the news continues. for others, check back with us a little lit baiter for the morning news and "cbs this morning." from the broadcast center in new york city, i'm scott pelley. -- captions by vitac

this is the "cbs overnight news." >> welcome to the "overnight news." i'm anna warner. there's just four days to go until new hampshire holds its first in the nation primary. and a new poll shows bernie sanders and donald trump with commanding leads. for the republicans, trump has the support of 36% of likely voters, followed by marco rubio with 15%, and iowa winner ted cruz at 14%. for the democrats, bernie sanders is leading hillary clinton 58% to 36%. sanders and clinton held a debate last night in new hampshire.

say. >> but the numbers just don't add up from what senator sanders has been proposing. that's why all of the independent experts, all of the editorial boards that have vetted both of us have concluded it is just not achievable. let's go down a path where we can tell people what we will do, a progressive is someone who makes progress. that's what i intend to do. >> thank you, secretary. senator sanders, just explain how you spent nearly two decades in congress and haven't gotten any of these things past. why do you think as president you'll be able to achieve big, new programs. >> i haven't quite run for president before. [ laughter ] [ applause ] let's deal with some of the comments that secretary clinton made. and by the way, sometime there is's a lot of drama here. i've known secretary clinton for 25 years and respect her very much.

every major country on earth, whether it's the uk, whether it's france, whether it's canada, has managed to provide health care to all people as a right, and they are spending significantly less per capita on health care than we are. so i do not accept the belief that the united states of america can't do that. i do not accept the belief that the united states of america and our government can't stand up to the rip-offs of the pharmaceutical industry which charge us by far the highest prices in the world for prescription drugs. number two, in the economy today, everybody understands that we need a well-educated workforce. this is 2016. when we talk about public education, it can no longer be k-12th grade. i do believe that public colleges and universities should be tuition free.

it's an expensive proposition. i do believe we should lower student debt in this country. we pay for it in my view by a tax on wall street speculation. the middle class bailed out wall street in their time of need. now it is wall street's time to help the middle class. >> look, i've just got to jump in here, because honestly, senator sanders is the only person who i think would characterize me a woman running to be the first woman president as exemplifying the establishment. [ applause ] and i've got to tell you that it is -- it is really quite -- it's really quite amusing to me. people support me because they know me. they know my life's work. they have worked with me and many have also worked with senator sanders. at the end of the day, they endorse me because they know i

i am not going to make promises i can't keep. i am not going to talk about big ideas like single payer and then not level with people about how much it will cost. a respected health economist said these plans would cost $1 trillion more a year. i'm not going to tell people that i will raise your incomes and not your taxes, and not mean it. because i don't want to see the kind of struggle that the middle class is going through exemplified by these promises that would raise taxes and make it much more difficult for many, many americans to get ahead and stay ahead. that is not my agenda. >> senator sanders, you have 30 seconds to respond. [ applause ] >> what being part of the

quarter having a super pac that raised $15 million from wall street. that throughout one's life raised a lot of money from drug companies and other special interests. to my mind, if we do not get a handle on money in politics, and the degree to which big money controls the political process in this country, nobody is going to bring about the changes that is needed in this country for the middle class and working families. >> yeah, but i think it's fair to really ask what's behind that comment. you know, senator sanders has said he wants to run a positive campaign. i've tried to keep my disagreements over issues as it should be. but time and time again, by insinuation, there is this attack that he is putting forth, which really comes down to, you

donations or speaking fees from any interest group has to be bought. and i just absolutely reject that, senator. and i really don't think these kinds of attacks by insinuation are worthy of you. and enough is enough. if you've got something to say, say it directly but you will not find that i ever changed a view or a vote because of any donation that i ever received. and i have stood up and i have represented my constituents to the best of my ability and i'm very proud of that. so i think it's time to end the very artful smear that you and your campaign have been carrying out in recent weeks -- [ crowd booing ] -- and let's talk about the issues that divide us -- >> let's talk about the issues. >> we both agree with campaign

>> let's talk about issues. >> i worked hard on that. i want to reverse citizens united. >> let's talk about issues. let's talk about why, in the 1990s, wall street got de-regulated. did it have anything to do with the fact that wall street provided to spend billions of dollars on lobbying and campaign contributions? well, some people might think, yeah, that had some influence. let's ask why it is that we pay by far the highest prices in the world for prescription drugs and your medicine can be doubled tomorrow and there's nothing that the government can do to stop it. do you think it has anything to do with the huge amounts of campaign contributions and lobbying from the fossil fuel industry? let's talk about climate change. do you think there is a reason why not one republican has the guts to recognize that climate change is real and that we need

do you think it has anything to do with the koch brothers and exxonmobil pouring money into the political system? that is what goes on in america. [ cheers and applause ] >> the "cbs overnight news" will be right back. that's fun. it's already dry! no wait time. this is great. it's very soft. can i keep it? (laughs) all the care of dove... ...now in a dry antiperspirant spray. this is mineral build up it collects leaving gross germ-ridden stains. clorox toilet bowl cleaner with bleach is no match for that. but lysol power toilet bowl cleaner eliminates mineral build-up effortlessly. so why choose anything

last year, falling pump prices put an extra $150 billion in american's pockets. the price of oil has dipped below $30 a barrel. it's all good, right? one big boost to the economy. what does this symbolize? >> the crash. >> reporter: well, not so fast. in west texas, $30 a barrel oil means a deepening economic disaster. what is this? >> it's a drilling contractor's yard. >> reporter: during the boom, what would this have looked like? >> empty, completely empty. >> reporter: to oil field consultant mike rsaco, this parking lot for drilling rigs symbolizes the american oil and gas industry going broke. in just the last year, more than 900 rigs were idled.

so each one of these rigs represents how many unemployed people? >> i would say a thousand each. >> reporter: each one? >> absolutely. >> reporter: how many do you think are sitting here? >> we quit counting when they got into the 30s. >> reporter: on the road between midland and odessa, it's all there to see. the collateral damage caused by low-price oil. the auction lots for heavy equipment no longer needed. for the repossessed cars and trucks for the people who have lost their jobs. the pump jacks that aren't pumping. >> a gallon of water is worth more than a gallon of crude oil right now. >> reporter: really? >> absolutely. that's another drilling rig north of town. >> reporter: until he was laid off last spring, mike made $1700, $1800 a day overseeing projects for a major oil company. worldwide, the oil and gas

275,000 jobs. since oil prices peaked at over $100 a barrel in mid 2014. for starters, demand for oil fell. in the past, opec has cut production in response. not this time. >> before the oil price collapse, the assumption is that opec would underpin the oil price by cutting production. but the key oil producers in the gulf, saudi arabia and the other gulf states, said we're not going to cut unless other people cut. >> reporter: daniel yergen is vice chairman of ihs, an international information company. and the pulitzer prize winning author of "the prize, a history of oil." >> saudi arabia's basic strategy is to maintain its market share in the global oil market, and that's been the starting point for them. >> reporter: at the expense of everybody else? >> yes. >> reporter: so began a huge

with saudi arabia and its opec partners pumping full blast. russia, too. and the united states. you've heard of fracking? pumping water into shale formations to free hard-to-get at oil and gas. well, fracking meant that the united states suddenly was producing a lot more oil. so much that for the first time in 40 years, we're exporting it. >> u.s. oil production went from 5 million barrels a day in 2008 to 9.7 million barrels a day in april of 2015. in other words, u.s. oil production almost doubled in a matter of just a few years. >> reporter: during the good years, midland and odessa, texas turned into boom towns. same story in williston, north dakota.

entrepreneurs borrowed billions of dollars to buy into the bonanza. workers flocked to the oil patch. >> i heard about all this big money. so i thought i could get a little piece of that pie, i suppose. >> reporter: so many they had to live in trailer camps. on cots in church halls. then the price crashed, thanks in large part to china's slowing economy. meanwhile, every day the world is producing something like a million and a half more barrels of oil than it needs. there's an ocean of it out there. in massive storage tanks. and right now, at least 100 million barrels are sitting in tankers, parked at sea. mike rasco just wants to hang on to his home. he never lived lavishly, even when he could have, so he could weather the bad times.

this is the fourth bust he's lived through. he knows it will end. as he looks for work every day, he just wonders when. >> i'm out of pride. i've got a beautiful wife and two good babies to take care of. i'll be a good oilman when it comes back around. by eating healthy, drinking fluids, these simple remedies with airborne. no other leading immunity brand gives you more vitamin c. plus it has a specially crafted blend of 13 vitamins, minerals and herbs. so when you want to support your immune system, take airborne, and enjoy living well.

cbs sunday when the denver broncos take the field against the carolina panthers. the mile high city and charlotte, north carolina are two very different places. but which is more super? we sent john blackstone and michelle miller to find out. >> last time denver was in the super bowl, i headed up to seattle to tour that city. get what? the seahawks won. so this time i'm here to offer a little leverage and to let you know, michelle -- >> let me know, john. >> that denver is a city that will always be on top. >> that is well and good, john, but panther pride runs deep in the south. and though no city can lay claim to this team that's headed to the super bowl, charlotte, which is where the city is based, has been working on a victory all its own. >> okay. >> keep pounding. that's the catch phrase of carolina fans, but it's also become the mantra of the city of

among the fastest growing cities in the south. >> sorry if i'm looking down on you, michelle, but denver is the mile high city. and talk about growth, about a thousand people a week are moving here. and it's the number one choice for millennials on the move. >> if you're planning to move in a new sofa for your big super bowl watch party, consider this -- 60% of all american furniture in homes originate in north carolina. >> yeah, that's nice, michelle. but not a whole lot of sitting here in denver, when it's sunny about 300 days a year, people are outdoors. that may be why denver is among america's fittest cities. >> john, have you even tried the barbecue here in north carolina? charlotte mayor jennifer roberts has. >> and we're here at spoon's

>> if you're craving a cheese burger, denver's mayor michael hancock tells me this american favorite was originally created right here in denver. i understand you have a bit of a wager going on with the mayor of charlotte. >> after the broncos win super bowl 50, mayor roberts will have to wear this peyton manning jersey in public. in fact, you might as well take it now. >> let's hope peyton manning doesn't throw like that. >> let's hope he does. i know we have a bet. i'm not going to wear a broncos jersey. newton jersey and some lovely cam newton socks are going to look wonderful on you when the broncos lose. >> nice shins. but really, cheese burgers? want to burn off some of those calories on a golf course, no better place than the carolinas where north and south carolina are among the top ten places to play. and here at quail hollow club, it's hosting the 2017 pga championship.

>> that's good to know, michelle, but colorado is in the top ten, too. and because of the altitude, the air is thinner here, your ball will go 10% further. >> you want to talk altitude? let's talk about the wright brothers who launched the age of aviation from the carolina coast. >> well, there are plenty of historical places here in downtown denver, like union station, which has recently -- what's that noise? >> oh, i'm sorry, john. is this bothering you? it's so addictive, this bubble wrap. the company that makes it, right here in north carolina. >> bubble wrap? here in denver, you could pop into a marijuana dispensary. since pot was legalized here in 2012 for recreational use, it's become a billion dollar business. >> marijuana is not legal here in the carolinas, not even for medicinal use.

what is this called? >> mvp punch. >> mmm. well, before prohibition, the bootleggers used to tote this stuff around and they came up with another carolina tradition -- nascar. >> here we go! whew-hoo! so, richard petty, mr. king. >> how did you do? >> you've been around here a few times. how do you think it went? >> a little slow to begin with, but a little more practice, you'll be right deld in there. >> need to spend some more time in carolina. >> no nascar here, michelle, but there's beer. >> cheers. >> thanks, jason. denver brews more beer than any other city in the country, including about 100 craft breweries like this one. and bear with me, michelle, while i tell you that colorado is also a pretty artsy place,

national endowment for the arts. for visits to museums, theaters, and concert venues. who wouldn't want to come see a show here in red rocks? and i will wait, i will wait for you it's a perfect sunday morning in my quiet little mountain town >> and we can also thank denver for the animated community of "south park." >> but here in north carolina, it's a real place. and let's not forget the state also is home to one of the very first public universities. unc. and its tobacco road rival, duke. which is the alma mater of our own charlie rose. he still has a home here in henderson, where he grew up. and really, isn't that all that matters? yes, i'm going to carolina in my mind

sunday's super bowl will be played in levi stadium outside san francisco. it's the newest stadium but still needs a little work. the struggle for game-day turf field. jeff glor has the story from super bowl city. >> reporter: super bowl city is sort of the center of activity here in san francisco, the old candlestick park has been torn down. the new 49ers home was opened two years ago, and not everything has worked out as planned. for $1.3 billion, you would expect levi stadium to be a comfortable fit for everyone. but on the field, frustration.

season. in october, the natural turf partially collapsed under the foot of ravens kicker justin tucker. >> he fell on the turf, and they've had trouble on the turf here. >> reporter: so for weeks before the super bowl, more than 600 tuns of new sod were brought in. ed works for the nfl, not the 49ers. and he does this every year. every postseason, the cite of the super bowl gets a brand new field. the grass is designed to withstand not just the players -- >> caught, touchdown. >> reporter: but the wear and tear what's become a massive mid the halftime show. n fed every single day. it's a living, breathing, growing entity and you can't >> reporter: this stadium has

are those over? >> the 49ers did a great job handling that. new stadium, everything is new in here. you work out the bugs. >> reporter: the other part of the structure that's gotten so much attention -- the technology. >> this stadium in and of itself came ready to go. most stadiums have to work to be ready for a super bowl. >> reporter: because it's new and it's in silicon valley. >> yes, both. >> reporter: there are more than 400 miles of fiber and copper cable, supporting 40 times the band width of typical stadiums, allowing fans to call, text, tweet, and watch instant replays from their phones at will. now on sunday, if the green can match the gadgets, the league is hoping for a pitch perfect experience. we will see how the field holds up. one positive, there was some concern about el nino and a potential soggy sunday. the forecast looks clear and sunny. >> and that's the "overnight news" for this friday. for some of you, the news continues. for others, check back with us later for the morning news and "cbs this morning." from the broadcast center in new
