A new abc News Washington post poll shows what we think about congress has hit a record low. Only 12 approve. 85 are unhappy about it. Jonathan karl is in washington with more on the poll. And president obama vows to fix the problems with his health care plan. Lets begin with the poll. No good news for anyone in washington. But republicans taking the biggest hit. Reporter thats right, george. This new poll shows that theres disapproval with everyone in congress. Republicans taking the biggest hit. 77 disapproving how they handled the budget talks that led to this crisis. And this next number should strike fear into the hearts of incumbents everywhere. Only 21 saying theyre incli inclined 25 , inclined to reelect their member of congress. 66 saying they want to look around. Looking for big changes right now. President obama, out there in the rose garden yesterday, talking about his health care plan. So many problems with the early launch of that. The president says, no ones madder about him about it. But he didnt give a lot of details about the fix. Reporter thats right. The president said and the white house has talked about a tech surge, bringing in the best and the brightest of the computer world to help fix this problem. We asked who. And the white house refers to us hhs. They say they dont have a specific list of who is coming in to help out. Kathleen sebelius was asked to testify before congress this week. She declined citing scheduling issues but she will come next week. She will get a grilling there. Jon karl, thanks very much. Lets get the other top stories from josh. Were going to begin with dramatic video. It may be tough to watch. It came in overnight. It shows an attack that raises concern about the upcoming olympics in russia, the security there. It shows the moment a suspected suicide bomber detonated a bomb on a bus in southern russia, killing six people and wounding dozens more. Officials believe the bomber was an islamic militant, part of an insurgency. They worry may now look to target this coming winters games. And two human Rights Groups are out with scathing reports this morning about u. S. Drone strikes overseas. The groups claim more civilians have been killed in pakistan and yemen, than the u. S. Has acknowledged. In fact, dozens more, including women and children. The white house claims that civilian deaths are exceedingly rare. And we learned overnight about a terrifying close call between two jumbo jets in the air. We saw it at the top of the show. One of the jets flying to washington, d. C. A lufthansa boeing 747 and a British Airways 747, apparently misunderstood orders from air Traffic Control over scotland. They turned towards each other. And again, theres no way to mock this up to make it look worse than it was. They came within 100 feet of each other. So close, considering the planes themselves are 60 feet long. This happened in june. British authorities just released the details. They are blaming the pilots for the error. Some great news for tens of thousands of morning commuters in the bay area in california. A deal struck overnight to end the fourday transit strike in san francisco. The Bay Area Rapid transit trains will be running this morning. Full service is expected by afternoon. Again, exceedingly great news for so many thousands in northern california. Caught on camera here in the boston subway, a woman who was apparently sleepwalking, stumbles right off the platform, on to the tracks. She hurt her arm in the fall. But look at the other riders jump in, lifting her back on to the platform. Again, hurting her arm, but only that. And finally, could be the best bargain ever. Look at this receipt. Its a guy named eric who was able to buy a ticket to game one of the world series for 6. It was actually a 3 purchase. But the fee on stubhub doubled that. Now, three similar tickets are selling for more than 800 a pop. Why would anyone sell a ticket that cheap . We have no idea. And im guessing the seller has no idea, either. Im going to guess somebody didnt hit a decimal point and a couple more zeros. If you could get on the airline thats been sending out the free tickets, you would be set. Life is good. Life is good, all right, josh, thank you. Now, to the mystery of the identity of little maria. American parents of baby lisa irwin, the little girl who disappeared in the u. S. A few years ago, now asking if their missing child could be maria. A global search is under way for her parents. Alex perez is in greece and has the latest for us. Good morning, alex. Reporter good morning, robin. The irwins are 1 of 8,000 calls and leads that greek authorities have received from around the world. Now, the roma couple appeared at the courthouse behind me. They are both headed to jail. While Police Continue hunting for marias real parents. The roma couple maria was with when police discovered her in last weeks raid is now behind bars. Awaiting charges on abduction and forgery charges. Back in kansas city, the family of baby lisa irwin, who vanished from their home in 2011, when she was nearly a year old is watching. They have contacted authorities. Baby lisa would be 3 years old next month. The familys attorney tells the Daily Telegraph that the irwins are 1 of 4 american inquiries about maria. The couple told the judge they adopted maria after her mother gave her to them. Our clients are claiming we never abduct this child. We just adopted. With a way nonlegal, thats where we can confess. Reporter but investigators arent buying it. They say he has a criminal record and has given conflicting accounts of how they got maria. And she was discovered with two different identities and claims to have given birth to 6 of their 14 children in the last 10 months. That has officials investigating whether the couple is part of an International Child trafficking ring. Their neighbor says their own children played with maria. And calls the roma couple good parents. Saying, in part, they always cared for the little girl. Dna tests confirm maria is not related to the roma couple. A pathologist concludes shes between 5 and 6 years old. And despite reports she could have ties to the u. S. , shes believed to possibly be from northern europe. Im not aware of any contacts that indicate shes american. Reporter this morning, maria is being cared for in a hospital, until her real family is found. Shes happy. Shes doing well. She communicates. And shes playing with toys. Reporter now, the irwin family attorney tells abc news they have reached out to the fbi for help, as well. Now, as for maria, were told she is in good spirits and playing with toys. If here real family is not found in the next six months, prosecutors tell us the formal adoption process to find her a new home could begin. George . Okay, alex, thanks. Lets get more on this from abcs chief legal analyst, dan abrams. The state department saying no evidence this is an american. But the irwins coming forward. So many families hoping against hope this could be their baby. This has given hope, now, to families around the world, who have missing children about this age. When it comes to the irwins, i remember when i interviewed them, when this case started, they were holding out hope that somehow, something would come forward. Theyd get some sort of tip, et cetera. The issues. Number one, this child, maria, seems to be ages 4 or 5. Baby lisa would be closer to 3. You have the state department coming out and saying, no indications that this is an american. But that doesnt rule it out. And i think all the families out there, including the irwins who have missing children, are going to hold out hope that maybe this is their child. And the crime of trafficking children, very serious. And this couple being charged with abduction. Well, thats right. The questions going to be, did they abduct this child . Or did they take in a child that they say maybe engage in what is effectively welfare fraud. Trying to get government aid they wouldnt have been entitled to. And thats the key distinction here. Were they involved in actually taking this child . The authorities are charging them with abducting a child. So, the authorities clearly dont believe their account. They gave numerous accounts about what happened here. Up to five different accounts. So, theyre in big legal trouble right now. Okay, dan abrams, thanks very much. All right. Thank you, george. Now, to a potentially huge breakthrough in the battle against baldness. Scientists say they have found a new way to grow hair. And it could be the next step towards better treatments for baldness. Lets bring in abcs chief health and medical editor, dr. Richard besser. Just tell us how this treatment works. This is exciting. They took skin cells that dont normally grow hair. They put them in a dish, treated them and turned them into hairgrowing cells. They then injected them back into skin that didnt have hair and hair grew. They figured out the instruction manual for creating hairgrowing cells. This could be a better method than the current methods that are out there. Thats right. The current treatments are getting existing air growing cells to start growing again. This is a different approach. It might be of real value for women who cant get Hair Transplants as often because they dont have as much skin that grows hair. This is early on in the research. This study, it was done on human skin but grafted on to mice. Before they would test this in people, how do you control the color of the air, the texture, the angle it grows. If they figure it out, they will test it in people. Its a few years off. You came in this morning very excited. Not just because of this in particular, but what it could mean in the bigger picture. Thats right. What theyve done here is theyve figured out how one of our types of cells operates. And the more we learn about that, it leads to treatments for all kinds of different things. Scientifically, this is a really big advance. Okay. Fingers crossed. Thank you very much. Big day for apple today. All you techies out there cant wait for the latest gadget. A new ipad expected to be unveiled in san francisco, at a time when apple needs a big hit. Our tech expert, neal karlinsky, has the story. Reporter this morning, apple will take its best shot in what has grown into a fiery battle for domination in the tablet wars. The company is expected to launch its latest ipad and ipad mini, including likely sharper screens, possibly thinner form and new colors. But will it be enough . Theres a lot of pressure on apple to put out something that will garner a lot of excitement. And huge refreshes of tablets that already exist is kind of a tough thing to pull off. This is what it looks like. Very thin. Reporter the pressure is on. Apple is no longer the leader in a market it invented in 2010, with the very first ipad. Today, android tablets, many of them cheaper and put out under a number of brands, have 50 Worldwide Market share, according to new research. Apple, now trailing at 49 . A steady drop from just two years ago. Todays new ipad launches in many ways mark the start of the holiday crush. When you look at the competition from microsoft to amazon to google, its really important for apple, today, to really show they are still the best tablet out there. Reporter whatever is revealed on stage by apple today will be fighting for attention in a more crowded and competitive market than ever. For Good Morning America, neal karlinsky, abc news, seattle. Exciting for a lot of people there. And, lara, you have something exciting, too. Yeah, really love this story. Its about an oklahoma teen who found a huge diamond at a state park. She heard about a young boy who found a 5karat diamond at arkansass state park. This is a story we did on gma. She convinced her parents she should try her own luck. The family spent the weekend at the crater of diamonds state park in arkansas, hoping to uncover a diamond in the rough. I didnt think i was going the find anything. Reporter 14yearold tana was two hours into her search of the 37acre park, when something shiny, about the size of a jelly bean caught her eye. I saw something goldish or shiny. It was not a Candy Wrapper or a marble. She came straight up and the minute she opened her hand, i knew she had something. Reporter park experts evaluated that something. And told her the news. Tana had discovered a 3. 85karat canary diamond. They hadnt found one in a very long time. Reporter the park has a kinders keepers policy. And tanas parents say that diamond is being kept in a safety deposit box. In august, michael found a 5karat diamond in the same park. That inspired tana to try her own luck. I had this gut feeling that i needed to walk. I named it gods jewel because i think that god led me towards it. Sure is pretty. And we want to thank koco, our station in oklahoma city, for sharing that story with us. Where exactly is this . I know. Two for two. A big one. Theres diamonds in those hills. This weekend. Weekend trip to arkansas. Road trip. But its going to be a little chilly when we head out. This is our step into colder temperatures. Were going to get right to the boards here. Were going to show you the big chill. Now, the front had kept it off the east coast, up until now. But todays the day, tonights the night, that that front starts to work through. And now, the colder temperatures will trickle in along the eastern seaboard from the midatlantic to new england. You started seeing the cooler temperatures with some snow in minneapolis. Now, the clippers are bringing in both things, the snow and the cold air. Big drop through the dakotas. Then they kind of hook, catch a ride on the jet stream, if you will, through a little of northern illinois, indiana, a light path of snow. And the temperatures, each successive one, will be cooler and cooler, until we settle into the right level for this time of year. The temperatures in boston with clouds and afternoon showers at 67. Portland, at 62. New york at 64. Thats probably the last of the 60s for a couple days. Tuesday trivia was brought to you by oxytrol. And all of the folks that like lakeeffect snow, are getting excited now. Because now is the time it starts to kick in on those eastern who are those folks again, exactly .
