seeing those last two striding up the 18th fairway. how about the fact the first time we really got to know who jordan spieth was on a national level as we welcome those of you joining us at the top of the hour to the final minutes, the final major of the year, the 97th pga championship. jordan spieth, 16-year-old jesuit high school in dallas. qualifies for the byron nelson. he's within three shots of the lead on the back nine on sunday and finishes 16th, a tournament that was eventually won by jason day, his first win in america. nick: jason was very nervous on that day and he knows how to handle it now. moved to another stage. jim: little did we know these two would be resurfacing and be such a big future of the sport, as rose attempts a putt for par.

nick: this is no fun this one. jim: to be a final-round 70 for justin. again, in all four majors made the cut. three top 10's, a second at augusta. it's either going to be here a share of third or fourth alone. [captioning funded by cbs sports division] [captioning performed by the national captioning institute, which is responsible for its caption content and accuracy. visit ncicap.org] jim: sixth at the open championship. colin swatton. he'll keep him focused. clates numbers and -- nick: yeah, keep plotting exactly where you want to land it. no need to be looking at that flag at all. jim: grace for third.

tonight on cbs begins with "60 minutes" and a monumental project 80 years in the making followed by a new "big brother," "madam secretary" and "c.s.i.: cyber." there's jason's wife ellie, who's from the outskirts of columbus, ohio, and their little boy dash. ellie is pregnant with their second child, expected to arrive the first half of november, right around the time of jason's 28th birthday. nick: got to be careful because jordan is going to be planning to throw this one in inside 10

feet. david: 185 yards. he has 5-iron. nick: no. i think he just blocked it a touch. jim: it's not that bad. really good shot. nick: that is the flattest approach. it's the perfect angle but once again, if jason can just fire it at that golf ball, that will do very nicely. that for me would be the spot to go for. david: i had my numbers the wrong way around. this is actually 1 5 for jason. he has 6-iron. 198, the shot that jordan just hit. it was 5-iron. but 6-iron for jason.

david: looks like he's done just about that. jim: that's going to be a good enough shot to enjoy the walk now. nick: say g-day to australia and welcome j-day to the major circle. jim: he's a great one to add, isn't he? nick: he sure is. it's what we've been talking about. we had the big three moons ago and now i think we're approaching on having another big three in the game of golf. jim: there are others who can wide than circle. nick: i said a couple of years ago big six. maybe we're going for the big

six. it would be very impressive for our game. jim: a little walk around what's called seven-mile creek. they'll emerge at the top and wisconsin will greet the man about to be minted as a major champion.

jim: on the bookend majors. these two performances -- spieth going wire to wire, tying the 72-hole augusta scoring record and then here -- >> ladies and gentlemen, please welcome to the 18th green, from australia, jason day! and from dallas, texas, jordan spieth! jim: spieth about to become number one in the world. as soon as he putts out. but day's performance, two putts away from becoming the first player in the history of the game to finish a major championship at 20 under par. nick: i hope he does. two putts, level 67's. i'm very proud i shot 18 under at st. andrews and then tiger

shot -- 25 years ago -- and then tiger shot 19 under 15 years ago. it's going to take a while before somebody shoots 21 under in a major, i'm guessing. jim: unless he holes the putt. could be 20 seconds away. nick: good thinking. how negative of me just to give him a two-putt, sorry. this is so impressive. the two leaders go out on a really difficult day. we weren't hamming it up at the start of the show, saying how the breeze was up. the greens were definitely shinier. hole locations were tough and we've got jordan at four under, jason day at five under today. jim: a look at that family waiting for this to finish. and it's a sweet family that leans heavily on colin and lisa.

like a big brother but like a big sister. they look after this two and the day families -- family travels around the pga tour in an -- motor home. inseparable at every tournament.

nick: you might be right, jim. [laughter] oh. jim: he's already starting to shea -- show a lot of emother, which you could see in his eyes when he filed make the putt on the 72nd at st. andrews. nick: i think he came on a mission after that. i think he's gone. jim: boy, he's worked hard at it, too. and he has often talked about just getting to this very day this point. wanting to win for his father alvin, who passed away when jason was just 12 years old and the incredible efforts that his mother made to get jason on

track and in the proper hands to teach him the game. off to boarden school. the golf component, seven hours away. spieth's putt. that was a fine effort too. his mom, who sold their house so jason could go to that international school and hook up with colin swatton, his caddie today, and focus not only on his school but his golf. so jordan spieth is going to shoot 68 here today. nick: yeah, level 67's for the major. sorry, jordan you were saying. jim: jordan is going to shoot 68. nick: yeah, and break tiger's record. jim: and he's now number one in the world. and he's applauding for jason. as jason steps in to finish it off.

nick: i hope he can see the golf ball through the tears. jim: a phenomenal talent and a major champion! ian: they've come a long way together, jim, those two. that's a great story. jason: hey!

jason: come here. ah. jason: thanks, may. appreciate it. thank you. thanks, mate. >> can we go home? jim: dash says can we go home? nick: yes. jim: we're going to be taking something with us. it is rather sizable.

bill: jason, congratulations. it has been quite a journey for you already, hasn't it? jason: it's been a long journey. i mean, just -- i didn't expect to ever go out and be on the pga tour. i'm being a little emotional here but it's an amazing feeling just the work i've put into my game ever since i was a 12-year-old kid and to be able to stand in front of a crowd like this today and win the pga championship is pretty special. bill: we've watched you visualize your shots all week.

how does the visualization of this moment compare to the reality? jason: i didn't expect i was going to cry. a lot of emotion has come out just because i've been so close so many times in major championships and just fallen short. just really close. and to be able to play the way i did today, especially in tough conditions, especially with jordan in my group, i mean -- i could tell that he was the favorite and you know, just to be able to play the way i did and finish the way i did was just amazing. bill: jordan didn't make it easy on you today. was there a key moment down the stretch that you felt was essential to wrapping this up? maybe the second shot at 16? jason: the second shot at 16 definitely helped but it looked like he had a tough lie, especially on the 16th hole but he got up and down. hitting the shot at 17 was a big confidence boost to be able to get on the green, two-putt there and hitting a drive down 18 the

>> cooper: lumber liquidators is the largest retailer of hardwood flooring in north america, with over 360 stores in 46 states and revenues of more than a billion dollars a year. but hardwood isn't the only product they sell. more than 100 million square feet of the company's cheaper laminate flooring is installed in american homes every year. lumber liquidators is a u.s. company, but much of its laminate flooring is made in china. and as we discovered when we first reported this story in march, it may fail to meet

health and safety standards because it contains high levels of formaldehyde, a known cancer- causing chemical. lumber liquidators has insisted ever since our report that its chinese-made laminate flooring is safe, but it doesn't appear that way based on what we learned from our own reporting, and from the work of people like denny larson. you want the company to remove all the flooring? >> denny larson: every single board. at their cost and replace it with clean flooring. >> cooper: how much is that going to a cost? >> larson: you know what? i don't care. because they're guilty of selling people product that could make them sick. >> cooper: these worried california homeowners, who didn't want to be identified, aren't waiting for lumber liquidators. they are ripping up their floors now. but many can't afford to replace the flooring on their own. >> larson: they don't know what to do. they have flooring that they think is making them sick. >> cooper: california environmental activist denny larson teamed up with richard drury, a prominent environmental

attorney, to test lumber liquidators' chinese-made laminate flooring. do you have any idea how much of this wood is in people's homes right now? >> richard drury: we believe there are probably tens of thousands of households in california that have installed lumber liquidators' chinese laminates that may exceed the formaldehyde standards. >> cooper: nationwide? >> drury: nationwide, it's probably hundreds of thousands. >> cooper: drury and larson bought more than 150 boxes of laminate flooring at stores around california and sent them to three certified labs for a series of tests. the results? while laminate flooring from home depot and lowe's had acceptable levels of formaldehyde, as did lumber liquidators' american-made laminates, every single sample of chinese-made laminate flooring from lumber liquidators failed to meet california formaldehyde emissions standards, many by a large margin. >> drury: the average level in lumber liquidators products that we found was over six to seven times above the state standard for formaldehyde.

and we found some that were close to 20 times above the level that's allowed to be sold. >> cooper: that sounds like a huge amount. >> drury: it's a startling amount. it was so high, in fact, that one of our test labs thought their machine was broken. >> cooper: the lab itself thought... >> larson: it hit the upper limit on the radar gun. and they thought it was broken. >> philip landrigan: it's not a safe level, it's a level that the u.s. e.p.a. calls polluted indoor conditions. >> cooper: would you want that in your home? >> landrigan: no. >> cooper: dr. philip landrigan of new york's mt. sinai hospital specializes in environmental pediatrics and exposure to toxic chemicals. he's talking about the results of another kind of test drury and larson conducted measuring the concentration of formaldehyde emissions coming off the laminates into the air of a typical home. >> landrigan: i would say long- term exposure at that level would be risky because it would increase the risk for chronic respiratory irritation, change in a person's lung function, increased risk of asthma. it's not going to produce symptoms in everybody, but

children will be the people most likely to show symptoms at that sort of level. >> cooper: children are featured prominently in lumber liquidators ads, and the company likes to promote the donations of flooring they make to habitat for humanity, ronald mcdonald house charities, schools, and community centers. >> trust the people over two millions families trust... the flooring experts at lumber liquidators. >> cooper: and on their website, lumber liquidators promises that all of their flooring "meets or exceeds rigorous emissions standards". and they say "we not only comply with laws, we exceed them." is that true? >> drury: that is not a true statement. >> cooper: is it legal to sell these boxes of wood in california? >> drury: no, it is not. it is illegal to sell these boxes of wood in california. we hope that they will not sell these products anywhere in the nation, because they are above the health-based standards that the state has set. >> cooper: drury and larson, who are backed by short sellers-- a group of wall street investors

who are betting the company is overvalued-- have sued lumber liquidators, accusing them of violating california's toxic warning statute. drury has also launched a class- action lawsuit against the company. it is legal for flooring to contain formaldehyde. the chemical is present in some of the cheap glues used in factories like this one in china. this footage was recorded by investigators hired by "60 minutes." formaldehyde is in the glues used to bind wood particles together to make the core boards in laminate flooring. the laminated top, which covers the core board, keeps most of the formaldehyde emissions trapped inside. but formaldehyde does leak into the air. how much is inhaled by homeowners depends on how much formaldehyde is in the glue and how much ventilation is in the home. >> larson: you're in a chamber, so you're living with it. you're sleeping in there. and you're constantly exposed. that's the threat. the constant exposure to a potent carcinogen over a long period of time. >> cooper: because formaldehyde

can cause myeloid leukemia and nasopharengeal cancer at high levels and respiratory issues as well as eye, nose, and throat irritation at even low levels, california has strict standards for how much of the chemical the core boards in laminate flooring can emit. every box of laminate flooring lumber liquidators sells carries this label, stating its carb phase two compliant. "carb" is an acronym for the california air resources board, which sets strict standards for formaldehyde emissions in wood flooring. congress adopted california's limits when it passed the formaldehyde standards act in 2010. that law is scheduled to take effect nationwide this year. drury and larson only had wood tested that was being sold in california. but we wondered if the chinese- made laminate flooring that lumber liquidators is selling nationwide also has high levels of formaldehyde. so we went to stores in virginia... florida... texas... illinois... and new york... and bought 31 boxes of it.

we sent the samples for testing at two certified labs. it turns out of the 31 samples of chinese-made laminate flooring, only one was compliant with formaldehyde emissions standards. some were more than 13 times over the california limit. both labs told us they had never seen formaldehyde levels that high. but when we took those test results to lumber liquidators' founder and chairman tom sullivan, he refused to accept the methodology as valid and points out the company is not required by law to test their finished products like we did. >> tom sullivan: it's not a real-world test of the laminate; it's not the way it's used. >> cooper: you say you don't believe in this test, but what you believe doesn't really matter-- it's what the california air resources board believes. and they believe in this test. >> sullivan: we will do whatever the regulations are. >> cooper: i just don't understand how a group can do tests on your chinese-made laminates and every single one of those failed to meet the emissions standards. >> sullivan: people have different reasons for this test.

this is a group of lawyers who are suing us selling short on our stock. >> cooper: but the short sellers are not conducting this test, it's these certified labs. >> sullivan: but it started with short sellers. >> cooper: one of the first people to raise questions about lumber liquidators back in 2013 was whitney tilson, a wall street hedge fund manager. he has shorted the company's stock but is not involved in any lawsuits against it. >> whitney tilson: in 16 years of professional money management, i've seen hundreds of companies do all sorts of bad things to get their stock prices up. but this has got to be the worst. >> cooper: whitney tilson studies the workings of companies he's interested in investing in, and he noticed the profit margins at lumber liquidators seemed unusually high compared to its competitors. >> tilson: when you see a commodity business suddenly double its profit margins, that raises red flags. >> cooper: because it's hard to have your profit margin double in two years? >> tilson: exactly. it's almost unprecedented for a company. >> cooper: based on those profits, lumber liquidators' stock price had gone from $13 a share in 2011 to $119 in 2013.

tilson suspected the company might be breaking the law. he learned there was already a federal investigation looking into the company for allegedly buying timber illegally logged in russia. u.s. agents raided lumber liquidators' headquarters in september of 2013. the company denies buying illegally logged wood but admits that the department of justice is seeking criminal charges against them. six months after he bet millions the stock would go down, whitney tilson got tipped off by someone familiar with lumber liquidators' operations in china, who said he was missing the bigger story. >> tilson: the much bigger story, he said, is that lumber liquidators was almost certainly purchasing formaldehyde-tainted laminated flooring in china. >> cooper: why would lumber liquidators purchase wood that's tainted with formaldehyde? >> tilson: the answer is greed, plain and simple. it's cheaper and net, it reduces the cost by about 10%. >> cooper: which in a business

with these kinds of profit margins, 10% means it's a lot of money? >> tilson: it's enormous. >> sullivan: our goal is to sell a good product at a good price. and we don't get the price by skimping on anything. we get the price by low overhead, huge volume, and being very efficient at what we do. and we're never going to a sell something unsafe. >> cooper: do you trust your mills in china? >> sullivan: we do. we have inspectors that double- check them. the mills are licensed by california... the chinese mills we deal with in the laminates are licensed by california. >> cooper: when you say it's licensed by california, what that really means is california says this mill is capable of making carb 2 compliant product. california is not saying every piece... every product coming out of this mill is carb 2 compliant. >> sullivan: but our specs are to make it to california standards. >> cooper: but for months, we had been hearing from former lumber liquidators employees, suppliers, and industry competitors that their chinese- made laminates are not being made to california standards. so we sent our investigators undercover to the city of

changzhou, the laminate flooring capital of the world. posing as buyers, and using hidden cameras, the investigators visited three different mills that manufacture laminates for lumber liquidators. employees at the mills openly admitted that they use core boards with higher levels of formaldehyde to make lumber liquidators laminates, saving the company ten to 15% on the price. at all three mills, they also admitted falsely labeling the company's laminate flooring as carb 2, meaning it meets california formaldehyde emissions standards, and the new u.s. federal law. at this factory, the general manager told investigators lumber liquidators is one of their biggest customers. >> this is a best-seller for lumber liquidators. >> for lumber liquidators? yeah? >> yeah. >> how long have you been selling this? >> from last year. >> is this carb 2? >> cooper: carb 2 means it's compliant with california law. but listen to what the general manager told us. >> no, no, no... i have to be

honest with you. it's not carb 2. >> can i get carb 2? >> yes, you can. it's just the price issue. we can make carb 2 but it would be very expensive. >> cooper: and that's the same thing the undercover team was told at all three mills they visited. >> all this stuff here, lumber liquidators... all their labeling is carb 2, right? but it's not carb 2? >> not carb 2. >> cooper: remember, lumber liquidators founder and chairman tom sullivan says that he trusts the chinese mills his company uses. employees at all three mills told us the laminates they make are not carb 2 compliant. i want you to look at this. we shared some of our hidden camera footage with him. >> sullivan: i don't know the whole situation here. i will guarantee we'll be in that mill tomorrow and test it. and that is not anything we can condone in any way, to save a cent. >> cooper: this concerns you? >> sullivan: yeah, yeah, of course.

>> cooper: is this acceptable to you? >> sullivan: if it's true, no. >> cooper: all three mills told us they falsely label your products as carb 2 compliant-- that's cheating. >> sullivan: that would be if that's true. >> cooper: nobody's ever reported this to you? >> sullivan: again, we will investigate it. if there is anything going on, we will stop it immediately. i don't know if it's true or not. i don't know what the whole story is, but we will investigate it immediately. >> cooper: it certainly calls into question not just these mills, but it calls into question your oversight of these mills. >> sullivan: it could, yes. >> cooper: two months after we first broadcast this story, lumber liquidators pulled all its chinese-made laminate flooring from the market nationwide. also since then, the chief executive officer resigned and the chief financial officer was replaced. the chief merchandising officer, who was in charge of sourcing from china, was fired. multiple state and federal investigations are underway by agencies including the consumer product safety commission, the

california air resources board, and the department of justice. this past week, a spokesman for the company said "lumber liquidators has taken and continues to take significant steps to investigate these issues and reassure our customers." >> cbs money watch update brought to you in part by: >> glor: good evening. germany's angela merkel said today greece cannot expect its debt to be cut. dish network and sinclair broadcast agreed to a short-term contract extension as talks continue. and fed minutes on wednesday could offer new clues about a potential september rate hike. i'm jeff glor, cbs news. dunkin' donuts k-cups

>> pelley: 400 years have passed since america's original sin, and still, riots are ignited in the friction between race and justice. as this debate continues, the smithsonian is completing a monumental project, the $500 million national museum of african american history and culture. the idea was authorized by an act of congress, which called it "a tribute to the negro's contribution to the achievements of america." the words are jarring because the act was written in 1929. as we first told you last spring, building this museum has been a long struggle, just like the story it hopes to tell. beside the monument to washington, a slave-holding president, the museum is

breaking free of the ground on the mall's last five acres. eight decades after congress framed a museum on paper, and then failed to fund it, the dream is being written, this time in steel and stone: ten floors-- five above ground, five below; its complexion, rendered in shades of bronze, a building of color against history's white marble. you've been at this nine years now. it's a big job. >> lonnie bunch: well, as i tell people, at 8:00 in the morning, i have the best job in america, and at 2:00 in the morning, it's the dumbest thing i've ever done in my life. this is a romare bearden from the 1950s. >> pelley: sleepless nights are all in a day's work for the museum's founding director, lonnie bunch, a scholar of the 19th century. >> bunch: clearly, this is... ought to be one of those moments where people are going to sort of reflect, pause. what does it mean once we open? what does it mean in terms of development opportunities?

>> pelley: in 2003, president bush signed the law creating the museum. congress put up $250 million, and bunch has raised most of another $250 million. >> bunch: i knew that this is where this museum would have to be, that this is america's front lawn, and this is the place where people come to learn what it means to be an american, and this museum needs to be there. >> pelley: so, we're on the ground floor. this is where the visitors will come in. this will be their first experience in the museum. so, what's going to be here? >> bunch: they will walk in either from the mall or from constitution ave, and they will run into amazing pieces of african-american art. >> pelley: when all of this is finally complete, what will america have? >> bunch: america will have a place that allows them to remember-- to remember how much we as a country have been improved, changed, challenged, and made better by the african- american experience. they'll have a place that they

can call home, but they'll also have a place that will make them change. >> pelley: but even this place is only space until you fill it. >> oh, my goodness. now, did somebody already look at some of these things for you? >> no. >> no?! >> pelley: seven years ago, the smithsonian began rummaging the attics and basements of america. >> this may have marked a milestone in his life. and what we don't know is what that was. >> but at least it gives me something i can investigate. >> pelley: 3,000 people brought their family history to 16 smithsonian events across the country. >> mary elliott: and this is the early free black family based out of baltimore? >> yes. >> pelley: it sounds like "antiques roadshow." >> nancy bercaw: it is like "antiques roadshow." >> pelley: mary elliott and nancy bercaw are curators. >> elliott: we have experts from across the museum field. experts in conservation. experts who understand about paper, about metals, about you name it-- fabrics, textiles. and they come in and they review objects for the public. >> the coating on this is in

pretty good condition. >> some of that looks like it's dried out a little bit. >> andon't put it near the air conditioning unit because that will dry it out too much. >> pelley: how do you convince someone to give up a priceless family heirloom? >> bercaw: do you know what? our museum pitches itself. all we have to do is tell the absolute honest truth. people have been waiting for us. people in america have been waiting for this moment. and so, literally, they just hand us things. >> elliot: and we're very excited like you are. >> pelley: thousands of relics were examined, but only 25 will be in the collection. this is one of them. >> renee anderson: this was actually a connection we made with the family. mr. jesse burke was an enslaved man, and he was charged with playing this violin and entertaining the slave holder and his guest. >> pelley: this is the smithsonian's warehouse in maryland, where the story is being written. and these are a few of the lines.

"received by grigsby e. thomas, the sum of $350 in full payment for a negro boy by the name of jim, about ten years old, this 31st day of december, 1835." jim would have been familiar with these-- shackles dating before 1860, bondage that might have been broken if the keeper of this bible had succeeded in his bloody rebellion. nat turner had said that god commanded him to break the chains. his bible was taken away before his execution. paul gardullo is a leader of the curating team. >> paul gardullo: i think many of us who know the story of slavery know about nat turner; know about nat turner from the perspective of perhaps a freedom fighter, perhaps a murderer. well, we know this is a religious person. we know this is a person who can read, and when you begin with

that, and those ideas, suddenly, the person of nat turner and your understandings of nat turner take on a whole new light. and i look to do that again and again, ways that we can see well-worn stories, stories we think we know, in a new light. >> pelley: you may think you know the story of a boy murdered for whistling at a white woman, until you are confronted with his casket. >> bunch: the story of emmett till is a crucially important story in terms of what it tells us, both about sort of reinvigorating the civil rights movement, but also it's a story of his mother, mamie mobley, who was really one of the most powerful people, who said that her son's murder should not be in vain, that it should help to transform america. >> pelley: no one was punished for the murder of emmett till. his body was exhumed in a later investigation, and the original casket was neglected.

>> bunch: but then the question was-- would we ever display it? should we ever display it? and i wrestled a lot with it, but then i realized i kept hearing mamie mobley in my head. and she said, "i opened this casket to change the world, to make the world confront the dangers, the power, the ugliness of race in america." >> pelley: a lot of the things that you intend to put on display are going to be hard to look at. >> bunch: what i'm trying to do is find the right tension between moments of sadness and moments of resiliency. >> pelley: one resilient moment came out of the blue. air force captain matt quy and his wife tina rebuilt an old crop duster, and in curiosity, they sent the serial number to an air force historian. >> matt quy: and he said, "are you sitting down? because i have some news for you."
