Today, in detroit, some more schools were shut down again as teachers called in sick in a continuing protest that has seen nearly 70 schools shut down this week. The teachers claim that the health of 46,000 students is in danger, and anna werner shows us why. Reporter some of these classrooms are cold . Very cold. Reporter at the spane Elementary School today, some kindergartners wore their coats in class. In several rooms, its just too cold for fiveyearolds. You can smell the mold through the hallway. Reporter School Counselor lekia wilson lead us on a tour. This is where the gym is. Reporter an entire section of the school is closed off, including the gym. You are seeing the result of rain coming right into the school. Reporter water leaking from the roof warped the wood floor. Now, the smell of mildew fills the air. You could have some champion swimmers come out of here. Reporter the School Swimming pool has been waiting for repairs for five years. Andre harlan is the gym teacher. How do you teach gym without a gym . Well, we do conditioning in the hallway. Reporter so, they walk the halls . Or run. Reporter the state took over Financial Management of detroit Public Schools in 2009. The district is still 515 million in debt. Ivy bailey is interim head of the teachers union. We kept talking and talking and talking and talking, and it was going on deaf ears. Nothing was changing, and teachers were just fed up. Reporter Darnell Earley is the emergency manager appointed by the governor to fix the problems. Certainly, if we dont get the money that we need to deal with the debt situation, thats only going to make it worse. Reporter and one of the things earley says the district cannot afford is a new roof for spane Elementary School. Doesnt that cry out for sort of immediate repairs in your view . Well, it cries out for the immediate action, and my understanding is that there is a reporter without an infusion of cash from state legislators, scott, the district says it will run out of money come april. Anna werner reporting for us tonight. Anna, thank you. The cbs overnight news today, iran released those ten u. S. Navy sailors we told you about last night who were detained when their boat sailed into iranian waters in the persian gulf. Tonight, david martin explains how a potential crisis was defused. Reporter in video released by iranian television, the boarding of the two navy boats seems peaceful enough, but this tells a different story. The navy crewmen look like theyre being held prisoner. Then the lieutenant in charge is asked what the boats were doing in iranian waters. It was a mistake. That was our fault, and we reporter that contrasts starkly with Vice President bidens account on cbs this morning that one of the boats had engine failure and drifted into iranian waters where they were, in his words, rescued. Theres no apology. Theres nothing to apologize for. When you have a problem with the boat, you apologize if the boat had a problem . No. And theres no looking for any apology. Reporter the crew was held for about 16 hours, and u. S. Navy doctors have now examined them and found no evidence of mistreatment. So, at least the incident came to a quick and satisfactory end, which, as secretary of state kerry pointed out, is saying something when it comes to iran. I think we can all imagine how a similar situation might have played out three or four years ago. Reporter irans foreign minister tweeted what really may have resolved it is irans desire not to derail countries. As part of that deal, the u. S. Is expected to begin releasing about 100 billion in frozen iranian assets in the next few days. Scott . David martin at the pentagon. David, thank you. Today, president obama hit the road to sell the ideas he raised in last nights state of the union address, his last. The first stop was omaha. The president spent 40 minutes meeting with High School Teacher lisa martin, who moved him with a letter in which she had expressed a sinking feeling of dread and sadness about climate change. Mr. Obamas address took a number of jabs at the rhetoric of donald trump, and then many were surprised when the republican response did the same. Major garrett is on the campaign. As frustration grows, there will be voices urging us to fall back into our respective tribes, to scapegoat fellow citizens who reporter following the president , South Carolina governor nikki haley, the daughter of indian immigrants, echoed his message of tolerance. During anxious times, it can be tempting to follow the siren call of the angriest voices. We must resist that temptation. No one who is willing to work hard, abide by our laws and love our traditions should ever feel unwelcome in this country. Reporter today, donald trump, who has called for a ban on muslims entering the u. S. , hit back at haley. Shes big on amnesty but very weak on illegal immigration. And so, therefore, we have a disagreement. I mean, she comes up to my office when she wants campaign contributions, and ive given her tremendous contributions over the years. Reporter trump has given haleys campaigns at least 7,000 since 2010. Haley acknowledged today that she was in part speaking about trump. I understood that when i hit republicans and democrats, i was going to upset people. What i did. Reporter Republican NationalCommittee ChairmanReince Priebus told us he thought haley was making a broader point. I wasnt sitting there listening and thinking about fighting within the republican party. I was just thinking about just the political rhetoric in general should be cooled down, and ive always said things like that. Reporter conservative firebrand ann coulter said on twitter trump ought to deport haley. Scott, priebus told us the republicans have had their fair share of drama and intrigue but predicted they would unify, create a presumptive nominee by april and do so, he said, before the democrats. Major garrett on the carolina coast. Major, thank you. The first votes in iowa are 19 days away. A poll out today puts ted cruz ahead of donald trump by just three points. Marco rubio was third.

I realize that a lot of other states feel we get a little special treatment, but, you know, we dont have times square. We dont get the ball that comes down here. This is our little thing. Reporter the remaining republican candidates have spent between 11 and 68 days apiece in the three democrats have spent over 30 days each. Anne petersen has seen many over the years. Like who .

We have that privilege here in iowa, and, if youve not met the president of the United States, its because you didnt really care to. It actually forces candidates to come here. Reporter holstein is heavily republican and energized. They know they may have a profound effect on u. S. History, and they relish the opportunity, as fleeting as it may be. You know, all you have to do is put forth a little effort and you can meet all of these people and its really nice. Could be. Reporter could be some day reporter the president . Yeah. Reporter theres a story here in iowa about an older gentleman who was asked if hed made up his mind yet.

Reporter in just the first three quarters of 2015, u. S. Airlines made almost 18 billion in profit. During that time, they were on pace to pass 2014s record of 3. 5 billion in baggage fees. Their planes flew 85 full, and the steep drop in fuel prices have the carriers cashing in. Passenger rita moss. Everything from the seat to the baggage being added on as extras, and the prices are still not decreasing. Reporter the very first thing anybody heard about the airlines in january was, they raised fares. Very modestly, and that was the first raising of fares in a reporter jean medina speaks for the airline industry. Whats good news for consumers is when airlines are profitable, customers, communities and investors and employees win because theyre reinvesting that money back into the business. Reporter the Airline Business is boom and bust. Since 1990, the industry has landed in the red 11 times. In 2005, it lost nearly 29 billion. First class is getting more luxurious, but in the back theyre squeezing us tighter than ever. Reporter Charles Leocha is the chairman of the travelers united. The fact that oil has dropped to such a low level has really given them a windfall profit. And some of that you would think might be shared with consumers, either in the forms of lower fees or lower airfares or perhaps by giving us a couple of extra inches in the airplane. Reporter the airlines say airfares actually dropped by about 3 last year, but, scott, that pales in comparison to the drop in oil prices. Kris van cleave at washingtons reagan international.

Ten United States sailors detained for a day by irans revolutionary guards are back at a u. S. Military base safe and sound. They were on board two small boats that strayed into iranian waters in the persian gulf. One or both of the boats suffered mechanical issues and were intercepted. It took some back room diplomacy between secretary of state john kerry and his iranian counterpart to get the men released quickly and avoid an international crisis. Pleased i am that our sailors were safely returned into United States hands this morning. [ applause ] reporter the sailors belonged to the san diego based riverine squadron one. The incident comes as the u. S. Is set to lift sanctions against iran as it fulfills its obligations under the recently completed nuclear deal. Voted just yesterday to increase congressional oversight of that deal, but president obama promised to veto that. David martin has more on the sailors capture and release. Reporter the ten sailors were picked up and flown by helicopter to a u. S. Military base where they will be debriefed to get their account of what happened. The pentagon says there are no indications they were harmed during their time in iranian hands. Two small navy goats, similar to the ones here, were en route from kuwait to bahrain when u. S. Officials say they suffered a the boats drifted into iranian waters and ten u. S. Sailors were overnight at an iranian base on the island of farcy. Speaking on state tv, the naval chief for the Iranian Revolutionary guard said the american vessels were engaged in unprofessional acts before being picked up and the sailors were taken into custody without much so the only people in america reporter any mention of the detainment was left out of president obamas state of the union address, as u. S. Officials worked to confirm the status of the crew. On tuesday, secretary of state john kerry spoke directly with his iranian counterpart and was personally assured the sailors would be well treated. As a former sailor myself, i know as well as anybody how important our naval presence is around the world. Certainly in the gulf region. And i could not be, and i know the president could not be uniform. I also want to thank the iranian authorities for their cooperation and quick response. These are always situations which, as everybody here knows, have an ability if not properly guided, to get out of control. And im appreciative for the quick and appropriate response of the iranian authorities. Reporter the sailors were on board Navy Riverine command boats, which normally do not carry sensitive equipment. The incident comes two weeks after Iranian Revolutionary guard ships fired off rockets within a mile of the american Aircraft Carrier harry s. Truman as it entered the persian gulf. The rockets were aimed away from the ship, but the incident drew a strong protest from the u. S. The navy will now conduct an investigation, but the u. S. Seems intent on getting this incident behind them as quickly defense secretary carter released a statement saying, we appreciate if timely way in which this situation was resolved. The National Guard is on the streets of flint, michigan, where tens of thousands of residents face a toxic water crisis. Lead levels in children doubled after the city switched the source of its Drinking Water in 2014. The states governor is coming under fire for not acting quickly to end the crisis. Reporter the governor has requested help from fema to deal with the problem. Almost two years ago, the city tapped into the flint river here for its water. But the water wasnt properly treated, corroding the pipes. This past october, the city switched back to its original water supply, but the damage was already done. Emergency management, water filters. Reporter volunteers and state troopers endured below freezing temperatures, going door to door tuesday, passing out bottled water and filters. But families still cant use the cant drink it, cant bathe in it. Its ridiculous. Reporter the governor is under fire for his handling of the nearly twoyear water problem. Earlier this week, an editorial in the Detroit Free Press called his response shameful. The paper compared it to Hurricane Katrina where the same lack of urgency delayed lifesaving aid. Monday, he said it wasnt until october 1st that his team learned there was confirmed lead in the water. But emails obtained by Virginia TechResearchers Show that state officials may have known there was a problem months earlier. More schoolchildren were tested for lead poisoning tuesday. Severe cases in those under 6 can cause longterm behavior problems. Following the water switch, elena richardsons children sores. Its been very difficult.

The term family ties gets a little ambiguous when you think of children conceived through a sperm donor. Especially when there could be hundreds of them. Mark strassman has the story. Reporter what are your thoughts going into this, nervous . Definitely a little nervous, yeah. Reporter Todd Whitehurst is walking into the unknown. What if they turn out to be strange and shy and they dont look up and theyre very antisocial. Reporter four kids are waiting for him, half mile away. I dont know what to say. I dont know what to do. 20yearold sarah mally. What makes you nervous . What do you say when youre meeting your biological family for the first time . I dont know. Reporter Todd Whitehurst is their biological father, the one theyre about to meet. Hes a 49yearold computer engineer who works for google. In 1998, then a stanford grad student, he noticed something in the school paper. They were running big ads, young men 18 to 30 needed for sperm donation. Reporter did you have any qualms about it . I guess my feeling on it was, the folks who end up going to a sperm bank really want children quite badly, and why wouldnt you want to help those people out . Reporter whitehurst, who has two children of his own from a previous marriage, never expected to meet any of his donor children. Sperm banks follow a protocol. All donor dads sign an agreement to remain anonymous. End are only given basic Background Information about their donor. His age, ethnicity, height, birthplace, education, so on. Clinics give each donor dad a unique donor i. D. Number, and thats become the gateway to improbable meetings like the one whitehurst is about to have. Its a bit nerveracking. Reporter and it never would have happened if not for one woman. Its an innate human desire to want to know where we come from. Reporter wendy cramer is the mother of a donor son. She saw how curious he was to learn more about his donor father and founded an online database called the donor sibling registry. Its a networking site for children who want to connect by matching their donor fathers i. D. Number. 47,000 people have registered, including 2300 donor dads. Kids want to know, i want to hear my donors laugh. I want to see him smile. I want to know what he thinks is i want to, you know, i want to look into his face. I want to shake his hand. Reporter Carrie Phelps felt that way. Ive always known i was a donor child from the earliest age, 2. You can imagine a parent with a 2yearold asking, wheres daddy . Reporter phelps, the daughter of a single mother, was 14 when she found her donor father. Phelps had Little Information about him, but spent two weeks plugging what she did know into an online search. She found seven possible matches. One photo stood out. From that moment, when i saw his face for the first time, it was just incredible. Reporter her donor dad was Todd Whitehurst. She emailed him, they met, became closer and even took vacations together with some of his other donor children. Like this trip to cape cod last july. I feel that its just the right thing to do. If the children want to meet, be available to meet. Reporter get ready to watch an extraordinary family moment. You must be keegan. Yes reporter eight donor children came together. Four of whom whitehurst had never met before, who are also meeting their siblings for the first time. Yeah, it gets complicated. Look how strong you are. Youre like an ox. Reporter what is this moment like for each of you . Its pretty awesome. This is insane. Reporter sarah mally, a student at bostons emerson college, had learned six months earlier that she and her twin sister, jenna, were donor babies. She contacted whitehurst through the registry and he helped arrange this family gathering. What was it like when you first walked out . Overwhelming. I was worried it would like a hello, its nice to meet you, whole big thing. Reporter just sitting here, did you feel fathers pride . Oh, absolutely. When i hear her talking about the hug, i want to give her a hug again. Yeah, shes wonderful. Reporter the reproductive industry does little to make it easy for donor dads and their children to meet. Nobody keeps track of the nobody keeps track of the kids. Theres no tracking whatsoever. Reporter wendy cramer says sperm banks ask mothers to report donor births but it is not required. And no Organization Links different clinics to track the total number of births from a single donor i. D. How many potential kids are out there from a single donor . Nobody really knows. The Largest Group that we have on our website, we know of a group that is somewhere around 200. Reporter 200 kids . Right. I dont know about you, but if i knew that i was i had 200 half brothers and sisters, i herd. It would feel odd. Reporter whitehurst donated to the same clinic for four years. How many times would you guess, ballpark . Probably on the order of 400 times, Something Like that. Reporter 400 times . Yeah. Reporter and consider this single donation at a sperm bank can produce as many as 24 sellable vials. His 400 donations could have produced 9600 vials for the clinic to sell. How many donor children do you know that you have . I have 22, that i know of. Reporter you could have a family touch Football Game and have enough players for both sides. Does that seem a little crazy . It does seem crazy, yeah. Theyve all turned out to be quite remarkable children. Reporter Carrie Phelps now stanford, just like her donor dad. I never felt like there was something missing, because ive been so lucky. Im so wanted. And thats something that i think a lot of kids cant say for certain. So being able to meet all of these totally different but at the same time very related honor for me to grow up this way. The cbs overnight news will be right back. Aw. So we use ky ultragel.

A new exhibit in new york city is unmasking the creators of some of your favorite super heroes. Superman, batman, spiderman and other classics. Mark albert takes us there. Reporter on a Street Corner in gotham, this has the power to freeze people in their tracks. Its one of four bat mobiles created for the 1960s batman tv show, and its the bait to pull you into an exhibit at the New York Historical society called super heroes in gotham. I love this. It says emergency bat turn lever. Bat ray projector. This would stop traffic anywhere. Reporter this is the exhibits cocurator. Its great to see them line up and just ogle it. Reporter its a show stopper. Its beautiful. Reporter generations of fans just the caped crusader and his ride, but with a whole universe of super heroes. Gotham may be a madeup world, but its hold on us is real. When you walked in this exhibit, what did you think . Like oh, my gosh, i remember seeing these comics. Reporter 12yearold zachary and his 7th grade class are some of the 4,000 students who will be whisked through the exhibit during its fourmonth run. They know who all the super heroes are, yet they dont know the history. I think it will give them ideas. I hope it will in terms of creating some of their own comic books or art. Reporter that inspiration comes from seeing the Humble Beginnings of extraordinary characters. And the men who created them. We have batman, number one. Reporter for example, batmans solo debut in this may 1939 issue. Or superman in action comics number one. Original sketches. Of steel that gave birth to the man of steel. And the wool and cotton costume worn by actor George Reeves in the 1950s Television Show the adventures of superman. The truth behind how the fiction began is as fan tasiccal as the tales these then would tell. Many of the original creators were the first in their families to be born in the u. S. Looking not to save the world, but just to survive in it during the Great Depression and then world war ii, when the country desperately needed heroes. These werent established artists in their 40s and 50s, these were teenagers. Yes, they were very young, looking for work. They were often discriminated upon because they were the sons of immigrants, most all of them the sons of jewish immigrants. Reporter so some cloaked themselves, changing their names Stanley Lieber became stan lee. The cocrow yeah for creator of spiderman and the hulk. Jacob kirtzberg transformed to jack kirby. Robert kahn disguised himself as bob kane. Cocreator of batman. And jerry siegal, who conceived of superman, even reportedly used more than one pseudonym. From this first superman cartoon in 1941, super heroes would take flight as the gravity defying media juggernaut we know today. Comics have proven so commercially indestructible, disney bought Marvel Entertainment for 4 billion in 2009 and has kept an endless line of super hero films coming. D. C. Comics has five tv shows on now, including super girl on cbs, about supermans cousin. Watched new show. And the comic conventions known as comiccon attract a rabid faithful, fuelling a booming market. One estimate puts sales of comic books and novels in 2015 at about 875 million. A record. We want younger people who will become artists at some point to realize that its possible and everyone has to start somewhere. Reporter even this daydreaming 9yearold, who drew batman in his Hebrew School book. 75 years later, that book is in the exhibit, and a grownup mark gerberg is a new yorker. The only way i could compensate for being a skinny little jewish kid who got beaten up all the time was to draw. Become a super hero in my own way. You never lose that initial fascination with cartoons. Reporter and those adults are passing that fascination onto their kids who, perhaps for dont need super powers to change the world. I do feel more inspired by them in that kind of way, that you can become bigger than you think you are. Reporter a belief they too with just a single bound. More tension on the korean peninsula. South korea fired warning shots after a north korean drone was spotted flying on its side of the border. The south is on alert after the north conducted a nuclear test last week. North korea is celebrating. It even brought a famous news anchor out of retirement for the occasion. Charlie dagata has her story. Reporter she put the bomb in bombastic when she broke the news in her signature style that north korea successfully tested the hydrogen bomb. Whether its true is a matter of debate. The announcement alone has already had an impact on both sides of the korean border. It was south koreas turn to up the jam. Blasting propaganda and pop music across the border. But pyongyang deployed its own weapon this week, to drop the bombshell that north korea had tested the hbomb. We will not disrupt or dismantle the program, she said, until the u. S. Reverses its vicious, hostile policy towards north korea. The 70 something grand mother the goto news anchor when the regime wants to impress the world. Often outfitted in traditional dress, her passion plays well in an isolated country that prides itself on the projection of power, real or imagined, under Supreme Leader kim jongun. Otherwise, she would be out of a job, obviously. Or worse. She barely made it through this jonguns father, kim jongil in 2011. We make this announcement with great sorrow, she said. In an interview with chinese television, she recommended a good anchor shouldnt shout but speak gently to viewers. Advice that may have fallen on deaf ears to up and coming talent. Its clearly a style that we in the west find funny. And now to phil with sports phil reporter but all that bombast hits home, back home says david kane, director of usc korean studies institute. Yeah, this is classic propaganda. Shes a woman, considered to be more of the he yet shes powerful and defiant. Reporter powerful and defiant but she remains a mouthpiece of the government. Shes been broadcasting for the countrys one and only station
