And tony bennett will be there at the invitation of nancy pelosi. Bennett is an outspoken proponent of gun control. Im brook baldwin, thank you so much for being with me here, lets go to wolf blitzer in washington. Hey, wolf. Happening now, a stricken ship plagued by raw sewage, some 4,000 passengers and crew describe conditions on the carnival try turn to be disgusting. And north koreas young leader defies the world with an underground nuclear test and now the world is responding. Im wolf blitzer, youre in the situation room. A picture of nightmare at sea. These passengers on the carnival triumph arent on deck to soak up the sun, theyre trying to escape the unbearable stench of raw sewage reportedly dripping down walls in long hallways. The National Transportation safety board Just Announced they will join after two days the triumph is now being towed to mobile, alabama, with more than 23,000 passengers whose vacation stories have turned into horror stories. Another 1,000 crewmembers are aboard. Reporter wolf, the carnival cr cruise ship triumph will dock behind me. When it gets here it will be greeted by members of the u. S. Coast guard and the nationshtio Transportation Safety board. Its no exaggeration to say this cruise to paradise has turned into a cruise through hell. Raw sewage, pretty bad. When you walk in the hallways, you have to cover your face, we dont have any masks for breathing. Its just disgusting. Reporter sundays fire which disabled the cruise ships engines, disabled many of the toilets t hot water and the air conditioners. The rooms are very hot unless you have a balcony room and then you can kind of get air and light, but if you have an interior room like mine, its pretty dark in there and pretty smelly especially if someone used your bathroom. Reporter as for food bread, boxed cereal and water and sodas and they just opened the bar to give people free beer and wine. Reporter fresh food is being brought aboard from other cruise ships. Tug boats are brewing the ship to port in the mobile, alabama. Meanwhile the crew are doing what they can. Were not having as much fun as what we had planned, but everyone seems to be doing okay. When the passengers disembark near the city of mobile, Officials Say they plan to have medical personnel available just in case anyone needs to get checked out. In the meantime, carnival making plans to get everyone back home providing them with a plane ticket, also providing refunds for the cruise they have just been on and as well, wolf a credit for a cruise if they decide to take another one in the future. So at least until wednesday night maybe even thursday, theyre going to be stuck on there. I assume they thought about getting another boat out and transferring everyone to another ship, but that was impractical, is that what the explanation was. Transferring people from large vessels like that to another vessel is very problematic out in the open seas and right now the ship has had some trouble with the wind, its actually listing a couple of addition, its not a safety problem, but they do have some environmental factors to consider as well. The best thing is to keep everybody on that ship and bring them right here to disembark. Much more coming up on this story, thanks very much. And to our viewers, you can read mother of the passengers descriptions of these very unpleasant conditions on board. Go to our website cnn. Com for more on that. Other news were following, cnn has learned president obama will talk about north koreas latest nuclear test in a state of the union test later tonight. The underground blast was so strong, it was actually registered as a magnitude 5. 1 earthquake by seismologists. Lets go to chris over at the pentagon. South korean officials estimate that this explosion could have been as high as 6 to 7 militons. The key thing is whether north korea managed to miniaturize the device, that is make it small enough that one day soon they would be able to marry a Nuclear War Head on top of a long range missile. Reporter on the eve of president obamas address to the american people, north korea sent a message of its own and mumsed its way into the state of union. They represent a serious threat to the United States of america. We have got to be prepared to deal with that. Reporter north korea detonated an explosion deep under ground. The u. S. Military deployed a special plane to japan that collects radioactive particles. But the plume has to extend outside north korean air space before the plane can collect samples. Well find out everything i have got to say tonight. Reporter sources say president obama adjusted his speech to mention north Koreas Nuclear ambitions, but after the u. N. Called an emergency meeting, the message is already being delivered. It will not be tolerated and they will be met with north koreas increasing isolation. Reporter that means sanctions, although how do you isolate the worlds most isolated regime is an open question. We are looking at the full sweep of options. Reporter Officials Say they will go to the iran playbook, sanctions specific individuals. You cant just play nuke kpleer whacamole. This test proves the u. S. Cannot crush the regime. If you cannot force them to comply, and we cant. The only choice you have left is one of engagement. Its going to be a few days before we know, but its going to narrow if north korea used uranium at this time. North korea can mine uranium at home. A lot of analysts out there are suggesting that the new young leader of north korea, chris, kim jongun, hes taking these provocative steps. The same thing we always hear, wolf, we hear a lot of that, but the one thing its always followed by is the caveat, we just dont know for sure. There is an incredible amount of frustration in the fact that they can never entirely pinpoint exactly what the motives are behind anything that north korea does, although youre right, there is a lot of sentiment that this may be more domestically driven more so than outward towards the world. Thank you very much. Chris lawrence over near the pentagon. We are awaiting the nomination of chuck hagels nomination to become the next defense secretary. The congress is meeting right now, it is expected to approve the nomination along party lines. The saga of chuck hagel is by no means over with yet.

New video has surfaced possibly showing one of the most wanted men in america and it could give police new clues as they fire the Police Officer wanted for multiple murders. Casey wians has latest. Whats going on . Theres a lot of activity especially in whats called the big bear area . We are hearing those reports of increaseded Law Enforcement activity in the big bear area, which is the area where Christopher Dorner was last known or suspected to have been, i just talked to the spokeswoman here at the police station. We do know that investigators are looking at more than 1,000 clues in their effort to find Christopher Dorner. Could this video of a man resembling murder system Christopher Dorner provide a clue to his whereabouts . The video obtained by tmz shows him walking through the aisles of a Southern CaliforniaSporting Goods store, hes carrying what appears to be one large scuba tank and one smaller one to the check out counter. Theyre going to look at the transactions that occurred at that time at that store and try to line up and make sure those transactions were done by dorner and that dorner is actually the one depicted in the video. Reporter investigators say last week dorner tried to steal a boat in san diego and his wallet and id were found near the san yisidro port of mexico. In los angeles, reported dorner sightings have poured into the command center. Yesterday when officials offered a 1 million reward for dorners arrest and conviction, the number of tips have increased to more than 1,000. U but investigators concede they still dont know where he is. Were hopeful something will break loose from the public. A door to door search continues in the big bear area. Residents with security cameras are being asked to check with dorner. Lapd families remain under Police Protection because they are linked to targets mentioned in dorners manifesto. We believe these are all very viable targets. The school in arcadia closed for a second day. Its pastor is related to someone threatened by dorner. One Law Enforcement source telling us, wolf, we really have to think out of the box with this guy. Hes been one step ahead of us. Of course well let you know if that continues if we get anymore information and confirm those reports that were hearing out of the big bear area, wolf. Correct me if im wrong, dorner had some sort of long standing connection to that big bear area, hes pretty familiar with the area, maybe thats why he went back there, is that right . Thats certainly one of the things that investigators have been looking at, a known associate of dorner, according to the marshalls arrest warrant, his family has property in the big bear area. Dorners vehicle when it was found on thursday on fire, was very near that property. So thats one of the things that they have been looking at to see if he had any kind of assistance from anybody or any connection to that area and may have been one of the places where he fled. Wolf . This search is about as huge a search in Southern California as we have seen in a long time. The folks really want to catch this guy . Absolutely, i cant tell you how on edge the Law Enforcement community has been for well over a week now. 50 members of the lapd and their families on 24hour being protected 24 hours by the security detail of the lapd because they are identified as potential targets of dorner, people that he has mentioned in his manifesto, very much on edge. Its one of those weird situations where the general public is nervous, but the Law Enforcement officers who are sworn to protect the again public are the most nervous because theyre the ones that dorner has vowed to target. Theres all kinds of tips coming in, including the l. A. Times claiming there was an exchange in fire between dorner and local Law Enforcement, is there anything you know about this. Theres nothing i can confirm other than i have heard those reports as well, wolf, and we just spoke with Public Information officers here at headquarters and they are in touch with the command post up there in the big bear area, so far theres nothing they can tell us to confirm whether those gunshots are related to dorner and his possible apprehension. They thought they were close to this guy and it turned out to be false alarms, if you will, so Everyone Wants to be very, very precise right now. This is obviously the most sensitive issue out there. Thats right. There have been false sightings in tijuana, false sightings in a Big Box Home Improvement store north of los angeles, more than 1,000 tips have come in since officials announced a 1 million reward for information leading to dorners capture and conviction. Well see if any of those turned out to be the tips that led them, if in fact thats whats going on, to Christopher Dorner. The l. A. Times suggesting that this gun battle possibly may be involving dorner, may have occurred when he was trying to burglarize a home as part of an effort to steal a car. We know his other car had been burned to a crisp, if you will, these are unconfirmed reports, there are a lot of local tv stations, the l. A. Times now suggests there has been an exchange of gun fire believed to be with dorner but we have not independently confirmed that, the l. A. Times tweetding just a little while ago, Christopher Dorner was engaged in a shootout with authorities in the big bear area. When we say federal authorities, fbi, local authorities, a lot of Law Enforcement are involved in this massive man hunt. And we also know through Law Enforcement that they expect and have anticipated that dorner is very well armed, very dangerous, his manifesto, they talked about his expertise as a marksman trained in the military. He delivered to our own anderson cooper, a medallion that had bullet holes in it. So theyre very aware that he is apparently well armed and its no surprise if in fact this is what happened that there has been an exclang of gun fire, wolf. And this new report, also from the l. A. Times, ill read it to our viewers, source says the gun battle occurred after dorner allegedly tried to burglarize a home and steal a car. The l. A. Times says dorners condition was not clear. We know he has been on the run now for several days after allegedly killing three people in the Southern California area, but these reports from the l. A. Times, local tv stations suggesting that theres been an exchange of gun fire and that they may, repeat may be they may have involved Christopher Dorner. We have not, once again, independently confirmed this. And we do know, casey, and i want to be precise, we do know, based on our own reporting heightened activity in that big bear area . Casey, we know theres been heightened activity in the past hour or two in that big bear area . Thats right, wolf and Law Enforcement officials i have just been told by my producer chuck connor, Law Enforcement officials now confirm to cnn that there has been an exchange in gun fire, they believe involving dorner. There are reports that he was involved in an attempt to steal a vehicle. We can now confirm that Law Enforcement has engaged Christopher Dorner in the area east of los angeles, those mountains near big bear, wolf. How far is that Big Bear Mountain area, how far is that from the Los Angeles Area . Its about a twohour drive from downtown los angeles, give or take a few, its a very windy road up there, several ways to get into the big bear area, its one of the local ski resorts that angelinos go to, its a day trip, there are a lot of residents in that area, some of these residences vacant for most of the year, Law Enforcement officials have gone door to door for the past week or so searching for dorner. Hundreds of Law Enforcement officers in that big bear area last week, those numbers have been scaled down gradually, on saturday there were 125 people searching for him. And just over the last couple of days, that number had dwindled to 30. And it appears that search has paid off, wolf. We dont know what happened that we have confirmed that theres been an exchange of gun fire and we believe it involves Christopher Dorner, we dont know what the end result is, if hes alive, what his cond
