Pelley good evening. This is our western edition. Today, General Motors linked seven more deaths to a faulty ignition switch and it nearly doubled the number of cars its recalling, from the 780,000 announced earlier this month to nearly 1. 4 million. Gm also said today the ignition switch is now tied to 31 crashes in which 13 people died. Right after the initial recall, cbs news tracked down a Gm Service Bulletin that showed the carmaker had known about problems with the switch for nearly a decade. Jeff glor has the new developments tonight. Reporter this crash of a chevy cobalt in wisconsin in 2006, which killed two teenaged girls, is part of the growing list of recalled vehicles. Margie beskau lost her 15year old daughter, amy. They knew something was wrong with the car before the accident. I just dont understand how they can knowingly put these cars out and still let people drive them. This is my child. This is my baby girl. Reporter earlier this month, General Motors recalled the 20052007 chevy cobalts and the 2007 pontiac g5s. Today, they added five new models 20032007 saturn ions, the 20062007 hhr and saturn sky, and 20052007 pontiac pursuits sold in canada. G. M. Did it because they had no other choice. Reporter Clarence Ditlow runs the center for auto safety. G. M. Is just cutting the losses. Its doing the right thing. It will save lives, but the issue is why were 13 lives lost . Reporter g. M. Says a heavy key ring or sudden jarring can switch the car off. That means no engine power, no power steering, no power brakes, and the airbags dont work. G. M. Filed this updated timeline with federal investigators. 2004 g. M. Became aware of at least one incident involving a chevy cobalt. An inquiry was opened, but after consideration of the lead time required, cost, and effectiveness of the solution, it is closed with no action. 2005 new field reports of engines losing power. A Service Bulletin issued to dealers in case customers complained saying, theres the potential for the driver to inadvertently turn off the ignition. The concern is more likely to occur if the driver is short and has a large and or heavy key chain, but no recall was issued. 2007, a g. M. Engineer began an investigation. New incidents of airbags not deploying or discovered. 2010, g. M. Discontinued production of the cobalt. This is going to go down as one of the top ten worst defects recalls ever, because it was covered up. Reporter last week, when we asked g. M. Why the recall did not include additional models announced today, we were told, we have no confirmed reports of incidents involving non deployment of frontal airbags occurring on these other investigation under the conditions of the cobalt g5 recall. Today, g. M. Told us the process employed to examine this phenomenon was not as robust as it should have been. We are deeply sorry and were working to address this issue as quickly as we can. G. M. , which says it will fix the ignition issue with democrats is facing a maximum 35 million fine from the government. But because people died, they are also potentially looking at a criminal penalty. Pelley jeff, thanks very much. A new blast of arctic air is driving across the northern United States. The mercury hit 27 below zero in longville, minnesota. Adding to the weather problems ice dams. Dean reynolds has more about them. Reporter considerable damage has already been done in tippecanoe county, indiana, where buckling ice ran wild, literally plowing trees and wrecking property. These pictures from ohio last week captured the speed and strength of an ice jam on the move. And many in the region are now fearing a similar fate. Im standing on the shoreline of the Kankakee River, and all of this ice in front of me has come up over the bank and threatens to keep on coming. This is probably 12 feet from the rivers edge, and look at it. Its like just mass destruction. You cant stop the ice. Reporter Steve Highbaugh has lived along the Kankakee River for a quarter century. You have a danger from pulverizing, but also then followon flooding . Correct. Reporter how does that make you feel . Well, not as good as i feel in july, thats for sure. Reporter the combination of the thaw and rain late last week got the ice going. But even when appearing motionless, carsized chunks are generating dangerous pressure on infrastructure, and the water underneath could quickly reroute sideways to get around the jam, causing flooding. Is this unusual . Yes, sir. This is not something you see every year. Reporter Trent Thompson is chief of operations for the illinois Emergency Management agency. We are looking at something that looks very still and very calm right now, but any at any time, it could cause massive problems where they break up and start flowing. Reporter tonight, scott, the residents along this river are watching it closely, knowing that the next move it makes could force them from their homes. Pelley thats quite a sight.

The governor of arizona is feeling heat tonight over a controversial bill that pits religious rights against the rights of gay americans. Jan brewer must decide by saturday whether to sign the bill or kill it. Jan crawford has our story. Reporter scott koheler is making a statement. We are open to everybody. Were not discriminatory in any way, shape, or form. Reporter the arizona sign shop owner has put that message on thousands of these signs which now are in storefront windows across the phoenix area. Its all part of a groundswell of opposition to a proposed state law that would make it easier for businesses to deny Service Based on religious beliefs. Critics say the bill is a license for discrimination against gays and lesbians. I think if this bill is passed into law in the state of arizona, that a lot of outside people are going to see arizona differently. And i just think in general its bad for business in arizona. It gives us a black eye. Reporter supporters say the legislation was designed to protect small businesses, like wedding photographers and bakeries, who may have religious objections to samesex marriages. Cathi herrod of the center for arizona policy helped craft the bill, called 1062. 1062 is about one thing and one thing only, that americans, arizonans should be free to live and work according to their faith. Reporter but just five days after the bill passed, theres intense pressure on governor jan brewer to veto it. National corporations doing business in arizona are calling for a veto, as is the arizona super bowl host committee, which says the law could jeopardize plans for the state to host next years super bowl. Now, yesterday, three republican state senators who actually voted for the bill sent brewer a letter urging her to veto it. The governor said shes going to decide by friday, and, scott, political insiders say they think a veto is likely. Pelley well keep following this, jan. Thank you very much. Now, along with the dollar and euro, there is a new currency called the bitcoins. You cant put it in your pocket. It trades only on the internet, and today one of the biggest Bitcoin Exchanges based in tokyo went bust after it was revealed that hundreds of millions of dollars worth of bitcoins were missing. We asked Anthony Mason to explain all this. Reporter in a Manhattan Park last fall, a small crowd gathered to buy and sell a new unregulated currency. On their smart phones, they traded a digital money called bitcoins. Youre a big believer in this currency. Im a big believer in bitcoins. Barry silbert is c. E. O. Of secretary market. I think its a currency like the u. S. Dollar or euro and i think its a great Money Transfer network like money gram or western uni. Reporter created by an anonymous Computer Programmer in 2009, bitcoins exists only as a code in a computer. A bitcoin can be sent directly from one owners digital wallet to another anywhere in the World Without going through financial institutions. I believe its a game changer. I believe bitcoin is as big as the internet itself, changing the way people think about money, change the way people send money, spend money is as big as the internet. Reporter retail shops have started accepting bitcoins. This restaurant in cambridge, massachusetts, honors them because customers like Japhet Stephens asked for it. I do see it as the new gold of the future. Reporter how easy is it to exchange . There are exchanges all around the world. Reporter its been a risky investment. The value of a bitcoin fluctuates on demand. A year ago, one cost about 30, and by december it soared to 1,200. But today, the price plummeted below 500. And Law Enforcement fears the currency is ideal for criminals. Last october, the f. B. I. Shut down the web site silk road, alleging it was a onestop shop for drugs and weapons sold using bitcoins. It was and im sure has been used for illicit activities, but frankly, so has u. S. Dollars and diamonds and gold over time. Reporter with the biggest Bitcoin Exchange planning to file for bankruptcy, sill pert announced plans today to create a new exchange and said hes consulting with major banks and with regulators. Pelley anthony, thanks very much. Heres a rare picture that we received. The president of the United States meeting today with the speaker of the house. It is their first oneonone meeting in the oval office since december of 2012. Were told that they agreed that there is much work to be done, though in this election year, theres considerable doubt that they will do it. President obama found another opponent on the phone today. He called hamid karzai, the president of afghanistan, and gave him an ultimatum concerning u. S. Troops there. David martin has been looking into this. Reporter you could say president obama finally gave up on president karzai today. He called him to say that, since the notoriously difficult afghan president would not sign a troop agreement, there was nothing for it but to start planning for pulling all American Forces out by the end of this year. The pentagon was already planning for the socalled zero option, but it was the first time karzai had heard it officially from the president of the United States. There are currently 34,000 american troops in afghanistan, and the top commander, general joseph dunford, has recommended keeping 10,000 there for two years after 2014, if the government of afghanistan first signs a security agreement. President obama left open the possibility of signing that agreement with karzais successor after afghanistan holds elections this spring. But he warned the longer it takes, the smaller the number of u. S. Troops that stay behind is likely to be. The president s phone call may not change karzais mind. He has refused to sign any agreement which allows u. S. Troops to continue their raids on afghan homes, but it will surely affect thinking elsewhere in afghanistan, where the army still depends on american support to carry out operations against the taliban. A senior pakistani official predicted that, if all u. S. Troops were to pull out, 30 of the afghan army would desert. And it will affect thinking among nato allies, which also have troops in afghanistan. Perhaps the most telling sign president obama has given up on karzai is that todays phone call was the first time the two men had talked since june of last year.

Pelley today, the food and Drug Administration began two days of meetings about a controversial medical procedure that critics believe could lead to designer babies. Dr. Jon lapook has been looking into this for us. Jon. Reporter scott, one of the issues scientists will discuss at this meeting is how Clinical Trials might be conducted. Its controversial because, in addition to the d. N. A. Of the mother and the father, material from a third person is used in the process. The vast majority of a cells d. N. A. Is located in the nucleus, but a tiny fraction is outside the nucleus in structures called mitochondria. These mitochondrial genes are inherited only from the mother, and in rare cases, can be defective. These defects can cause problems such as blindness, muscle disorders, and neurological illness. One proposed technique would work this way a womans nucleus is removed from her egg, leaving behind her unhealthy mitochondria. Her nucleus containing the majority of her genes replaces the nucleus in the donor egg, leaving an egg with the mothers nucleus and the donors healthy mitochondria.
