. good morning. i'm nancy cordes. >> and i'm anthony mason. here's some stories we'll be looking at on this saturday. the heat is on. heat blanketing much of the nation sparking wildfires. the president is with his idol just miles away. how will the president help the critical nelson mandela. the courts of appeal overturned the california same-sex marriage ban ties the knot. the tigers are coming. asian tiger mosquitoes, that is. they're aggressive, they carry

disease, and they're invading state after state. that and much more on "cbs this morning saturday" on june 29, 2013. and good morning. welcome to the weekend. welcome nancy cordes, good to see you. >> good to see you, too. they're dealing with some big heat in the west. 106 degrees in phoenix. >> we'll have some great guests for you in studio 57, including a fantastic band, the mavericks. they're back after nine years with a live performance in our second cup cafe. our oldest fine dining restaurant, delmonico's. we're going to talk about him serving up some dishes in the restaurant where they were invented. a record heat burning up much of our country.

it's dangerous, it's constant and causing misery for millions of americans. the western part of the nation is suffering, expecting highs of triple digits today. bill whitaker has the latest from los angeles. >> reporter: this fast-moving fire threatened homes and forced evacuations east of los angeles, fed by tender, dry brush and temperatures topping near 100 degrees. 1ç9ç#v the upper 90s, helping to spark this fire near a busy freeway. all across the west, summer is off to a sizzling start. it was hotter in phoenix than kiro, egypt. it was so hot in colorado, the city of boulder called off its

marathon. >> it's hotter than an oven out here. >> reporter: the national weather service has issued heat warnings skpand advisories in almost every western state. the reason? a huge dome of hot, dry air stretching from the pacific to the rockies. >> the more stagnant air mass, the hotter it gets and the more uncomfortable it gets out there. >> reporter: evelyn taft is a meteorologist for los angeles. >> we're basically looking at historic heat right now. we haven't seen something quite like this in maybe ten years. >> reporter: in california, people are seeking relief wherever they can find it. utilities are bracing for a surge in demand for electricity. steven berg oversees the state's power grid. >> this is just the beginning. it's expected to get hotter and stay that way into the middle of next week. for cbs this morning saturday, i'm bill whitaker in los

angeles. >> so how long should we expect these blast furnace conditions to continue? meteorologist craig setzer is tracking our heat wave. good morning, craig. >> good morning, nancy. it's unlikely to end any time soon, unfortunately. typically we think of it being hot in the desert southwest, but this is excessive heat. again, temperatures well above 110 in many locations. the 129 just shy of 130 forecast there in death valley. it hasn't been 130 degrees there in over 100 years, and 117, that would tie the all-time record high for las vegas. the reason for the heat? it's a big bubble of high pressure, and typically the hot, high pressure bubbles don't move a lot, so the hot that we see will likely continue through much of the upcoming week. now, the only good news in this or the downstream result is this dip in the jet stream thanks to that big heat bubble which means warm conditions for the

midsection of the country, but unfortunately looks rather stormy for the east coast for much of the weekend and the early part of the upcoming week. anthony and nancy? >> so no relief for a little bit. craig setzer, thank you. president obama is in africa for the second part of his tour of africa. he talks with south african president jacob zuma, but his thoughts are not far from nelson mandela, who is critically ill nearby. >> reporter: good morning, anthony. the press conference that president obama and south african president jacob zuma just had is breaking up, and i can tell you for the first time he addressed where a 21-year-old college student was killed. the president offered condolences and said the united states will not take sides in that democratic dispute in the

streets of alexandria and throughout asia, but he wants talks to be conducted in a peaceful manner in terms of the democratic evolution in egypt and very troubled by this outbreak of violence. also, the top job is to protect the u.s. embassy and top people in egypt. also concerned about nelson mandela, the president will not visit the ailing mandela in the hospital, but he will meet with the mandela family today, and at the top, the president talked about mandela's reach and legacy. >> nelson mandela and this nation speaks to the yearning spirit, that touches race and balance of this country. that's what nelson wants, and

that's what he can represent to the world. >> reporter: the president is trying to increase u.s. development throughout africa. this is the president's first extensive trip in the south sahara in his presidency. late in the game in development opportunities in africa. the president said they will compete against china, brazil, turkey and india. from major in jo hhannesbur we go to debra. debra, what can you tell us? >> it's become a sign of obsession, sifting through government statements for frank information, really, on nelson mandela's condition. he's been in the hospital just over three weeks, the

now, that statement was made, as i said, in sawita. she was addressing the media there. the family has been visiting mandela for the past 22 days. nelson's former wife and also his current wife, she's been by his side for much of that time. the official word used to describe nelson mandela's condition remains critical but stable, and exactly what that means medically, however, is unclear. members of the family will take a brief break from visiting mandela today, some of them for that planned meeting with president barack obama, but that will take place away from his hospital. at the hospital outside, members of the public continue to gather

with increasing vigor, and the walls outside the hospital pasted with tributes of what is extraordinary love between mandela and his people. >> what a scene there. thank you. the former vice chairman of the joint chiefs of staff is under investigation for allegedly leaking classified information about a covert cyberattack on iran's nuclear facilities. senior correspondent bill plant is in our washington bureau with the latest. bill, good morning. >> morning, anthony. that's right, the latest target of a leak investigation is no d disgruntled hacker. he's a retired four-star marine general. james cartwright, whose nickname is hoss, was once the joint chairman of chiefs of staff. >> i'll always be personally grateful to hoss for his friendship and partnership.

>> reporter: but now cartwright is the target of an investigation into the leak of information about a u.s. cyberattack on iranian nuclear facilities. a year ago, the "new york times" published details of the stuxnet virus, believed to be a joint israeli project that sub t. he was accused of making the information public to aid president obama's reelection. >> since i've been in office, my attitude has been zero tolerance for these kinds of leaks and speculation. >> reporter: cartwright has not been charged but has been informed by the justice department that he is a target. his attorney, greg craig, responded in a statement. general jim cartwright is an american hero who served his country with distinction for four decades. any suggestion that he could have betrayed the country he

loves is pre pposterous. he went on to say he has attacked the problems of the nation with more vigor than many. >> bill plant in washington. thank you, bill. the father of national security leaker edward snowden believes his son will return to the u.s. under certain conditions. he asked that he not be jailed before trial or subject to a gag order, and that he is tried in the venue of his choosing. edward snowden is charged with espionage. >> the scandal will be one topic on tomorrow's "face the nation" on cbs. his guests will also include wendy davis, who successfully

had a filibuster on a bill fighting abortion. chris perry and sandy speer said "i do" in san francisco before hundreds of supporters on friday. 90 minutes in los angeles, jeff catami and paul za ril rillo we married. george zimmerman admitted to shooting trayvon martin last year. we heard from several key witnesses this week, but they all had a different version of what happened. so how credible are any of them? >> i think they're all credible in their own way. whenever you have a case like this, you have eyewitness testimony and earwitness testimony. and in real life, no people will hear or see the same thing. and that makes their stories

very credible. however, when you talk about credibility, they believe what they saw or heard. it doesn't mean what they saw or heard is the truth. there is a distinction. and ultimately, the burden of proof in this case is always on the prosecution beyond a reasonable doubt. so if you say three people saw and heard three different things, they all believe it's true. they're not here to lie. ultimately, you're left with reasonable doubt. >> so these were all witnesses for the prosecution, but will some of them end up helping the defense? >> oh, big time. and i think yesterday we really saw it with jonathan good. here you had exactly what the defense was looking for. the defense says, hey, wait. george zimmerman didn't go gunning to assassinate trayvon martin. george zimmerman was a neighborhood watch volunteer, according to the defense, saw some specific activity, and at

some point somehow he winds up in a scuffle with trayvon martin and he's on the bottom. he's being pummelled. he's the one in fear of his own life. so jonathan good comes along, called by the prosecution, and what does he say? the man on the bottom was george zimmerman. that's huge for the defense. absolutely huge. >> ricki, the trial began with the defense attorney in his opening statement telling him knock-knock jokes. i don't know how well that went over with the jury. it maybe impossible to tell. he also had testimony exchanged with one of the witnesses. what impact do you think that will be? >> i think there are different impacts. the studies are region. i've been talking about this as long as i can remember about opening statements. 80% of jurors' minds are made up at the end of opening statements. then it's the lawyer's job to keep someone saying, oh, yes, i made the right decision at that

point. it's hard to change that. having that knock-knock joke, i would say, was a bigger ror becau error because that ended his credibility with george zimmerman. however, i would say he came back shining. his cross examinations have been really very, very effective. and when you have the star witness, trayvon martin's girlfriend, who is there for the prosecution, and you have someone like mr. west who can expose her not only being unsure but actually as not telling the truth, i think that goes a long way. >> we heard some 911 tapes being played this week. let's take a listen to a snippet from one of them and then i want your take on them. >> are you following him? >> yeah. >> okay, we don't need you to do that. >> what does that tell us about what happened? >> the best piece of evidence thus far for the prosecution is that 911 tape, plus the neighborhood watch coordinator, both of whom say you are not

supposed to follow someone you think is suspicious. you are not supposed to be, in essence, the neighborhood vigilante. you're supposed to be someone who calls the police and backs away. that's strong evidence for the prosecution. >> you think zimmerman is going to testify, ricki? >> i don't know. i thought so in the beginning. but i tell you this, if i'm trying this case, my very first murder case that i ever tried, if i were trying this case, they have it in evidence that george zimmerman has said that he acted in self-defense. so they may not have to put him on. you know, a dagger to my heart every time i put a client on the stand and i go, oh, they're killing my case. and it's their case, it's their life. in a case like this where you have a tragic, tragic death, you may also have a very sincere defendant. >> you never know which way it's going to go.

thank you very much for joining us this morning. a third suspect has been arrested in connection with the murder case of aaron hernandez. meanwhile, authorities believe hernandez may have been involved in a double murder last year in boston. as our boston reporter reports, that may have uncovered a motive for last month's murder. >> reporter: a week and a half after oden lloyd's murder, days after the spotlight turned on aaron hernandez, the district attorney says investigators now have three men they've been looking for. earnest wallace, carlos ortiz, and, of course, hernandez. >> we have three individuals in that car at that time. >> reporter: wallace, who is from hernandez' hometown of bristol, connecticut, turned himself in to police in south florida where his mother lives. he faces a charge of accessory after murder. >> we were advised that he was possibly armed and could be

dangerous. several officers approached mr. wallace, and as a precaution, he was taken into custody. >> reporter: police found his silver chrysler back in connecticut, where another hometown friend, carlos ortiz, cried during his extradition hearing. once in attleborough court, though, more composed. evidence shows he has talked to investigators about his time spent near the murder scene on the morning it happened, admitting he had a gun here june 17. so far a weapons charge is all he faces. >> at this point, i'm not expecting further charges. >> reporter: hernandez, the only one charged with murder. but the district attorney leaves the door open. >> each day something new develops. >> reporter: no chance for any of these three men to get out on bail, at least not at this point. and that suspect in florida, earnest wallace, is expected to make his way up to massachusetts to face charges here sometime next week. for cbs this morning saturday,

i'm christina hager in north attleborough, massachusetts. sarah murnigan, who suffered from a double lung transplant, they knew the set of lungs would be marginal, but they had no choice. >> we were told there was a 1 in 100 chance she would live on the current lungs she has. we didn't feel there was a decision to make there. it was all scary, but it was very clear we needed to go ahead and take this risk. >> sarah is on a ventilator this morning. she will undergo additional surgery on monday. in order to get this transplant, sarah's family sued to change national lung transplant rules.

the book on amazon.com will not be published on what is another blow to paula dooeen's reputation. the sale of deen's cookbooks had been the one bright spot for the chef. retailers like walmart and target also cut ties with deen after she acknowledged using racial slurs in the past. monday is looking like a very bad day for millions of american college students. because the senate failed to reach a deal, student loan interest rates will nearly double to 6.8% on july 1st for more than 7 million students. that adds thousands to the cost of a degree. joining us now is carmen wong ulrich, president of risk engineering at poly tech here in new york. what kind of increases can students expect to see? >> big ones, really big ones.

this is now the biggest personal debt outside of mortgages that we have as a nation. we're up to a trillion dollars. what does 3.4 versus 6.8 really mean? that's the difference between $5,000 in interest or $11,000, in general on average, in interest. it really doubles those payments and it's big trouble for students. this is incoming students and federal loans. >> so if you're looking to take out a student loan coming up, this will affect you. >> exactly. we have until august until student loans will be taken out, but on july 4th weekend, everyone is off, on the 10th they will decide to go retroactive or make it from that point. >> does that mean anything in the end for students if they go retroactive? >> it means a lot more money, a lot more payments. you look at the data, and for kids under 30, two out of five

end up in delinquency in the first five years. that's huge. that's 40% of folks who owe the money. remember, student loan debt cannot be discharged in bankruptcy, so this is on par with buying a home, and it's not a debt you can get out from under of. >> so at this point, carmen, if you're just starting the process of taking out a student loan, what should you be doing? >> as i mentioned, this is a huge responsibility. it's not a rite of passage, this is an investment for you, so you want to take it seriously. make sure to lower the cost of college before you apply for loans. what kind of college? full-time, part-time, where you're going to go, and then research those loans. if you have trouble with repayment, make sure you put something in action. you can go to fina.org. actually graduate in four years. the biggest way to cut down on the price of your degree is to actually graduate so you can have a degree to go into the

workplace and make a return on the investment. >> great advice. carmen ulrich, thank you for being here, we appreciate it. it's 23 past the hour. here's a look at your weather for the weekend. coming up, they're called asian tiger mosquitoes, and they're just as ferocious as they sound. they're spreading to more and more states, and we'll look at the threat. and later, three-quarters of americans live paycheck to paycheck with minimal savings or none at all. what you can do about it. you're watching "cbs this morning saturday." ,, goodnight.

it does speak to ray donovan a little bit, but right now he's such a flawed, deep, complicated dude. he blurs the right and wrong, but also he has a sense of right and wrong. is he a dark man to you? >> i'm not talking about happiness with ray because i'm not a very happy guy, but i think there is -- the show's creator and writer gave him a power that is conflicted. >> he's a hollywood fixer. what does that mean? >> he works for a high-end law firm, fixing the problems of hollywood actors, people like that, studio executives. every once in a while there are problems that fall outside the

legal boundaries of what one can do and they call ray. >> he sounds a bit like george clooney's character in that movie. >> it is similar. >> what's interesting about this to me is you're seeing really great television coming from showtime and hbo and netflix. it's really happening in terms of the business you're in. >> i was shocked. you know, script after script was just really remarkable on our first season. and also the production value. one of the difficult things is shooting 12 one-hour films over the course of a year. >> you said there was a time you wouldn't even think of doing television because you didn't want to do the same thing over and over again. >> that's the problem. what i struggle with in theater is three months of the same character drives you insane, and one of the things that's great about serial television is the character develops and the character grows. ,,,,,,,,

chicago sports fans are known for cheering on the bulls and the bears, but yesterday it was all the blackhawks as the city's champions took to the streets for celebration. >> about 2 million people turned out to honor the team's second championship in four years. it gave the blackhawks a day in the sun. >> gorgeous. welcome to cbs this morning saturday. i'm anthony mason. >> and i'm nancy cordes. one of the worst things about the summer, mosquitoes. they see us as walking banquets, but the asian tiger mosquito is just nasty. >> they first appeared in texas seven years
