i'm ron claiborne. on "world news" this saturday -- under pressure -- those crucial 48 hours have passed, the cap is holding, but what happens next? bp has a choice to make. scorched earth -- blistering heat makes every state in the country. it was the hottest june on record. what does the rest of the summer hold? the enemy within -- suicide hits an all-time high in the military. this young soldier was saved. now the pentagon is using his story to save others. jobs rule -- the company that guarantees its workers that they will never be laid off. could it be a model for other companies? and wedding secrets -- our reporter on the trail of the supersecret details of chelsea clinton's wedding. so why exactly is the secret service in upstate new york? good evening. those crucial 48 hours have passed in the gulf of mexico.

late today, bp announced they're leaving things as they are for another 24 hours with that cap holding the oil safely underground. as long as there are no signs the well is leaking, the company says they have some breathing room before they decide to collect oil once again and bring it to the surface. now there are new calls for bp to reopen this well so they can figure out how much oil has leaked during the last three months. abc's matt gutman joins us live from buras, louisiana, with the latest. >> reporter: government officials are reminding us that is just a temporary solution. officials are reminding us that is just a temporary solution. but bp has been couching that relative success of the seal with a double negative, saying, get this, there's no sign that the well is saying, get this, there's no notwithstanding all that notwithstanding all that pressure. tonight, we're told from bp officials that no news is good officials that no news is good news. tonight, visibly less oil near tonight, visibly less oil near the spill site. and 5,000 feet down, on the murky seabed this 80-ton cork, called a stacking cap, is murky seabed this 80-ton cork, called a stacking cap, is holding. >> as long as it's holding, the pressure that's building inside of it, that's a very good sign. in a nutshell, they have this

well under control. >> reporter: and with the well under control, bp has decided not to decide. >> the test was set up that it was to be a 48-hour test but there was always the provision that under certain circumstances the test could be extended. >> reporter: and it has. it could even be extended for weeks. they have that extra time because so far there are no signs the well is leaking. eventually, bp may decide to open the seal and pump all the oil to ships on the surface. but shutting in that oil means they may never know how much leaked into the gulf during those 86 days. and the head of the house subcommittee on energy says it's a number we need to know. representative markey wrote, in the event that additional oil collection should prove necessary, bp must measure the 100% of the hydrocarbons flowing from the well so we can determine the actual flow rate once and for all. under u.s. law, bp would be fined up to $4,300 per barrel per day if gross negligence is proven.

meaning bp's bill on day 86, using the government's highest estimates, could total more than $22 billion. and bp has been vastly underestimating the size of the spill for months now. at first by a factor of 60. and there's some suspicion that bp may never want an accurate number of that tally ever to surface. ron. >> matt, nearly $22 billion, that is a staggering amount of money. >> reporter: yes, it is, and that doesn't mention the claims from fishermen to stockholders and of course the cleanup. bp has shelled out $3.5 billion so far and more. we're learning that work on the cleanup could continue here for years, ron. >> it could go a lot higher than that $22 billion. thank you, matt gutman. the oil may not be flowing, but there's still a lot of activity going on above the wellhead. reporter ted oberg was on the water today. >> reporter: ron, as the well

testing closed in and surpassed the 48-hour mark, it was quiet out here. no recovered oil being burned from those ships. quiet doesn't mean things are winding down. on board, they're constantly monitoring the more than 60 ships and rigs out here at the site. they're nervous about the potential for anything to go wrong. but they're also watching the news, and they know how important this is. they say it's a great sign but only a first step. as we flew over the site, we didn't see a whole lot of oil. remember, it had been more than a day and a half at that point since the well had been capped. but as we flew a little further, there were miles of that rainbow sheen and still lots of heavy oil remaining to be picked up. >> ted oberg with our houston affiliate ktrk. thanks very much, ted. now to the heat -- in most heat waves, there's at least one part of the country that can gloat while they watch the rest of us suffer. not this time. take a look at the map. nearly every 1 of the 48 lower states saw temperatures reach 90 degrees today and at least 10 states hit 100 degrees or higher. eric horng joins us now live

from chicago. eric. >> reporter: good evening, ron. people have been coming here all day to the chicago lakefront to try to cool off. here and in every corner of the country, relief is hard to come by. sticky. steamy. sweltering. from california to connecticut, millions are baking. >> you do have to do a lot of rehydrating, all day long. >> reporter: in the southwest, it's hot even by desert standards. the mercury climbing well into the triple digits in phoenix, las vegas, and even denver. >> our morning lows are becoming is warm than the afternoon. it's not excessive whatsoever. but overall, it's oppressive heat and people just cannot cool down whatsoever. >> reporter: lightning sparked small wildfires near los angeles, as the heat index soared past the century mark. >> it's, what, 90 degrees already, 8:00. >> reporter: even northern cities are roasting with temperatures in pierre, south dakota, more than 15 degrees above normal. in chicago, where thousands gathered to watch the new "transformers" movie being filmed, the heat, unlike the film, was anything but science

fiction. >> it is blistering hot. the sun's rough. >> very nice and toasty. probably fry an egg on the sidewalk. >> reporter: this latest coast to coast heat wave comes on the heels of the hottest june on record and the warmest first half of any year on the books. so far this summer, the heat is blamed for at least 13 deaths in maryland, 5 in california and 4 in new york state. scientists point to el nino and the effects of global warming as well as the jet stream further north than usual preventing cooler air from moving south. >> water, sunscreen. take breaks when we get tired. think that's how we're dealing with it. >> reporter: here in chicago, this is the fourth straight day of 90-degree temperatures. for much of the country and in particular the northeast, a break from the heat may be days away. ron. >> okay, thanks, eric horng reporting from chicago. while the first family got a bit of a break from the weather. as they enjoyed their weekend in maine. where it was only 81 degrees, where they were today. the obamas toured an historic lighthouse.

in acadia national park. and then got a little hiking in. but the president, meanwhile, was turning up heat on the republicans in his weekly address. >> too often, the republican leadership in the united states senate chooses to filibuster our recovery and obstruct our progress. i think these senators are wrong. we can't afford to go back to the same misguided policies that led us into this mess. we need to move forward. with the policies that are leading us out of this mess. >> and we turn now to our chief white house correspondent jake tapper. jake, the president is sounding more partisan here than usual. can we expect to hear more of this heading into the midterm elections in november? >> reporter: absolutely, midterm elections, they're usually referendums on the party in power and every white house wants to change that dynamic, make it a choice election, and that's what you see here. president obama is leading the way in making the argument that it's a choice between president obama's policies and president bush's policies. so they're trying to reclaim the 2008 momentum that way.

>> jake, the republicans are countering that even a year and a half into his own term, the president is still running against president bush, as you just noted there. is that a fair criticism? >> it's absolutely fair. in fact, in our interview with vice president biden that's going to air tomorrow morning on "this week," you'll hear him use the term "repeal and repeat." and that what means is he thinks he's -- accusing the republicans of wanting to repeal the things that obama has done, health care reform, wall street reform, and repeat the ways of the past, of the bush administration. you will hear bush's name mentioned quite a number of times. >> jake tapper in washington, thanks very much. jake has an exclusive interview with vice president biden tomorrow morning on "this week." and in his weekly address, the president also blasted republicans for blocking an extension on benefits to the long-term unemployed. but that impasse may end this coming tuesday when a west virginia official, the new senator there,

carte goodwin, will take over late senator byrd's seat. 15 minutes later, they will vote. it is expected to pass. still, many people remain out of work. and many of them can only wish they had the guarantee that one american company offers its workers, never to be laid off. david kerley has that story tonight. >> reporter: with unemployment hovering near 10%, millions of americans can only dream about what mark wells has -- a guaranteed job, even in the depths of the recession. >> i was on reduced hours, but i was able to go in and work every day, and i saw a paycheck coming in. >> reporter: wells is one of the thousands of workers who make welding machines at lincoln electric, a cleveland company that promises, even in the worst of times, no one will be laid off. in this recession, how could you not lay off workers? >> because we don't lay off workers. it's as simple as that. if you make a commitment that you're not going to do it, then you find ways not to do it. >> reporter: not only no lay-offs, but these workers are paid at least 20% more than their peers, including an annual bonus that averages $28,000.

>> i have some place to work for the rest of my life, you know. well, until retirement. >> reporter: it's a way of doing business which grew out of the company's founding during the industrial revolution. john lincoln and his brother james, sons of a preacher, believed in the golden rule -- treat others as you would like to be treated. lincoln electric did not devise this system as part of a social experiment on worker satisfaction. this is about profits -- for the company and the workers. in bad times, hours are cut. in good times, mandatory overtime. but employees have to buy their own health insurance. and the company demands high output, even timing workers with a stop watch. if they don't measure up, they are let go. >> if everybody contributes, the company will be successful. and if you don't contribute, you won't be here. >> reporter: lincoln has been the subject of business school studies, even a new book. but few modern companies have followed lincoln's lead of guaranteed employment. >> given what we've gone through over the past year with 8.4 million people, surely we can find ways of organizing the

economy where you can make a profit and not destroy people and their families and communities. >> reporter: in cleveland, they think they have something special. for many, it's a family affair. mark wells got a degree in geology, but followed his father into the factory. >> i spent 35 years there, and i don't regret a minute of it. i've got what i got today because of that. and we've had a good life. >> reporter: most lincoln employees admit the work is hard, but that is the "no hard, but that is the "no lay-off tradeoff." david kerley, abc news, cleveland. in kansas, some serious injuries to children returning front a church camp. their school bus rolled over in a crash. eight children were taken to local hospitals. one was airlifted to kansas city in critical condition. 29 children and 4 counselors were on board that bus. still ahead -- on "world news" this saturday -- the dramatic rise in the death toll in the military, from not enemy bullets but suicide. a holocaust survivor and his

family danced and laughed at the site of former death camps, an insult or defiant celebration? and a small town trying to keep a big secret. so if i switched to progressive, i could save hundreds? yep. but that's just the start. we have a great loyalty program. i'm listening. stick with us, and you keep earning bigger discounts and benefits like accident forgiveness. plus, it's free. wow! great. now let's get you initiated into the program. what is that? watch. here you go -- automatically enrolled. painless, right? totally painless. rewarding loyalty. now, that's progressive. call or click today. bolt that burrito. no matter what life throws at you, you can take the heat. until it turns into... heartburn.

june, you may recall, was the deadliest month of the now nine-year war. and it's not just the enemy that is threatening u.s. troops in combat. sometimes it's their own demons. the suicide rate has hit an all-time high. the army reports 32 confirmed or suspected suicides in june. the highest number on record for a single month. with soldiers killing themselves at the rate of one per day, the pentagon is now reaching out to its troubled troops using their own words. here's abc's clayton sandell. >> reporter: soldiers in combat face pressure and stress few of us can imagine. no one knows what can push even the most battle-tested warriors over the edge. >> my whole universe just came crashing down. >> reporter: this army specialist joseph sanders hit his breaking point when his wife asked for a divorce. >> i grabbed the rifle off the wall, put my rifle up to my chin, put it on semi and pull the trigger. >> reporter: it didn't go off. now sanders and his fellow

soldiers -- >> i was angry. >> i self-destructed. >> reporter: -- are telling their stories in a new suicide prevention video released this week by the u.s. army. >> i couldn't move. i couldn't think. everything was just like a big cloud over the top of me. >> reporter: earlier this month, army officials had been encouraged by a drop in suicides. then in june, the number spiked. >> it is extremely frustrating because even when you see the numbers go down in a month, it really doesn't offer you anything. i mean, there's still a needless loss of life that takes place. >> reporter: so why is it happening? the army says it's a combination of factors including money troubles, substance abuse and failed relationships. some of the cases aren't even combat related. many of the national guard and reserve troops who committed suicide hadn't even been deployed overseas. as for specialist sanders, he wasn't just lucky, fellow soldier albert godding had seen the warning signs and disabled his rifle. >> godding walks in the door after all this happened.

i looked at him and i said, godding, where's my firing ring? he said, sanders -- >> -- how'd you find out? he's like -- >> -- i tried to kill myself. he says, yes, i took your firing pin. you were warning me. >> reporter: as the army learned, sometimes even chaplains need help. >> see, i'm embarrassed that i'm a minister and assisted suicide. but i'm not embarrassed that i healed. >> one thing we're working very, very hard to do is to get rid of the stigma involved with behavioral health issues. >> reporter: if the army can do that, the hope is many more soldiers will see the warning signs before it's too late. clayton sandell, abc news, washington. mexican officials say that drug traffickers are now using a terrorist tactic for the first time, car bombings. this week, one gang lured federal lawmakers to the aid of annen jured man. when they arrived, they deton e detonated the car bomb.
