President trump is calling on the United Nations to do more to stop a Nuclear Threat from north korea. The president s remarks come amid increasing tension over the possibility of war as American Warships sail closer to the korean peninsula. Yesterday mr. Trump held a meeting at the white house with ambassadors from the u. N. Security council. He urged them to be ready to impose stronger sanctions against the north korean regime. The status quo in north korea is also unacceptable. And the council must be prepared to impose additional and stronger sanctions on north Korean Nuclear and Ballistic Missile programs. This is a real threat to the world. Whether we want to talk about it or north korea is a big world probd s a problem we have to finally solve. People have put blindfolds on for decades. And now its time to solve the problem. The white house says the entire senate will be briefed on the north korean threat tomorrow. On monday, the Trump Administration said the president discussed the quote, urgent security challenge with german chancellor angela merkel. On sunday night, mr. Trump also spoke with japanese Prime Minister shinzo abe and chinese president xi jinping. Chinese media say xi told President Trump he hoped all parties would exercise restraint. Now north koreas detention of another american citizen is adding a dmu point of friction between the u. S. And north korea. Adrianna diaz has the latest from beijing. Reporter tony kims detention was confirmed by the university where he taught. While the circumstances around his detention are unclear, it complicated an increasingly tense relationship between the u. S. And north korea at a time when both sides are open to military action. With the uss carl vinson heading to the korean peninsula, north korea continues the show of defiance. A statement from the Pyongyang University of science and technology confirmed that tony kim had been detained as he was about to leave the country, after spending several weeks teaching at the school. Kim is the third american currently being held in north korea. In 2016 Otto Warmbier was sentenced to 15 years of hard labor after he allegedly stole a banner from a hotel. Then a naturalized citizen was sentenced to ten years for espionage. This is typical north korea when theres so much tension. Reporter Bill Richardson has negotiated prisoner releases from north korea. They use these detainees from the United States as bargaining chips. They always want something in return. Reporter since the arrest, the regime has continued its war of words, threatening australia with a Nuclear Attack for its alliance with the United States. And on sunday, north korean state media took aim at the u. S. , writing, our revolutionary forces are combat ready to sink a u. S. Nuclear powered Aircraft Carrier with a single strike. Some of these releasees have led to at least a dialog with north korea and thats a step forward. Reporter with no direct diplomatic ties, the u. S. Is working with the Swedish Embassy in north korea on kims case. He was with his wife when he was detained. She wasnt and is believed to still be in north korea. The u. S. Ambassador, nikki haley, issued a stern warning. She said the u. S. Is not trying to pick a fight with north korea but warned the regime not to give us a reason to do something. Ambassador haley appeared on cbs this morning. She discussed the north korean standoff and efforts to free the american citizens being held in pyongyang. Can you tell us more . Everything we know about the arrest and detention of a u. S. Citizen and what we can do about it. Well, i think right now were trying to gather information, and of course this is something we never want to see happen, but i do think that its north korea just trying to show their strength again, and what were going to say is its not going to work. And these are challenging times, but its not one where were afraid to make a decision, and i think were going to handle it properly and i think well have to use china to do that. What considerations are there about options . Well, we have to discuss that. And i think thats all part of the discussions that will have to take place. We always want to get every citizen out alive and healthy and make sure that theyre being treated properly. So those are the things well start to work on. The former new mexico governor said these are used as a bargaining chip. Do you agree with that . And do you think negotiations are possible at this point . I think its absolutely a bargaining chip. Thats what their intentions are. Whether thats the case or not is something entirely different. What were dealing with is a leader who is flailing right now. What hes trying to do is show his citizens that he has muscle, whether its through his rhetoric or actions, thats what hes trying to do. What we have done is partner with china and the rest of the International Community to put pressure on him. You saw the Security Council last week condemn north korea for their testing. I think youre going to continue to see pressure on north korea. We have said for quite a while now that the United States is not looking for a fight. North korea doesnt need to give us a reason to have one. And i think theyre panicking right now. I know that President Trump spoke with the chinese president xi last night. What more does china need to do . Well, i think china is really in good faith doing quite a bit. They are trying to put pressure on north korea, what we have said is we want you to put more pressure on north korea, whether thats with coal, whether its with oil or other sanctions. Taing with the leaders of north korea and telling them they dont need to do anything. So i think chinas been a really great friend of ours. The way they came together with us to do the Statement Last week showed we are united about wanting north korea to stay away from Nuclear Threats. Rex tillerson said last week that the u. S. Is looking to pressure north korea to reengage with us on a different footing. What does that mean . They need to stop misbehaving. That means they need to not use force to reengage. We dont want to see a nuclear north korea. They dont need to challenge us with missiles and talk about how far they can go and challenge our military bases in the area. Right now we not going to talk with north korea until we start seeing good actions come from them. Believe made it very clear. Thats exactly what they want, bilateral communication. Were not going to do it. Until they show us they are in good faith not going to test missiles, we will not talk with them. What we will do is continue to talk with china to get that message to them.

One more way youve got what it takes to protect. As President Trump nears his 100th day in office, former president obama held his first public event since leaving the white house. Mr. Obama addressed the crowd of mostly College Students yesterday at the university of chicago. It was a return to the foundation of his political career. Mr. Obama taught law at the university before being elected to the senate in 2004. His president ial library will be built next to the campus. The former president did not talk about his successor or delve into partisanship. Instead, he focussed on Young Americans and what he says is the most important thing he can do in his next job. So, whats been going on while ive been gone . [ laughter ] on the back end, now, of my presidency, now that its completed, im spending a lot of time thinking about what is the most important thing i can do for my next job . And what im convinced of is that although there are all kinds of issues that i care about and all kinds of issues that i intend to work on, the single most important thing i can do is to help in any way i can prepare the next generation of leadership to take up the baton and to take their own crack at changing the world. Because the one thing that im absolutely convinced of is that yes, we confront a whole range of challenges from economic inequality and lack of opportunity to a criminal Justice System that too often is skewed in ways that are unproductive, to climate change, to issues related to violence. All those problems are serious. Theyre daunting. But theyre not unsolvable. What is preventing us from tackling them and making more progress, really has to do with our politics and our civic life. It has to do with the fact that because of things like political gerrymandering our parties have moved further and further apart, and its harder and harder to find Common Ground, because of money in politics. Special interests dominate the debates in washington, in ways that dont match up with what the broad majority of americans feel. Because of changes in the media we now have a situation in which everybodys listening to people who already agree with them. And are further and further reinforcing their own realities. To the neglect of a common reality that allows us to have a healthy debate and then try to find Common Ground and actually move solutions forward. And so, you know, when i said in 2004 that there were no red states or blue states, theyre United States of america. That was aspirational comment, but i think its, and its one, by the way, that i still believe in the sense that when you talk to individuals one on one people, theres a lot more that people have in common than divides them. But obviously, its not true when it comes to our politics and civic life. And maybe more pernicious is that people are just not involved. They get xenical acynical. And give up. And we have low participation rates that translate into a further gap between whos governing us and what we believe. The only folks who are going to be able to solve that problem are going to be young people, the next generation. And i have been encouraged everywhere i go in the United States, but also everywhere around the world to see how sharp and astute and toll rant and thoughtful and entrepreneurial our young people are. A lot more sophisticated than i was at their age. And so the question then becomes, what are the ways in which we canat pathways for them to take leadership, for them to get involved . Are there ways in which we can knock down some of the barriers that are discouraging young people about a life of service . And if there are, i want to, i want to work with them to knock down those barriers and to get this next generation to accelerate their move towards leadership, because if that happens, i think were going to be just fine. And i end up being incredibly optimistic. There are a lot of different ways to engage, i think is important. Because sometimes people think youre not running for office, or its not election day. Theres no other ways of getting involved. And the ptas a perfect example of the kind of thing that we want to encourage. There are a bunch of writers out there and social scientists and thinkers who would argue that one of the problems we have with our politics right now is that the mediating institutions, the unions, the churches, the pta groups, the rotary club, a lot of the voluntary organizations that used to exist like sororities and paternities used to bring people in together to work on issues, that those have declined. And the statistics show that people are less likely to be involved with various organizations in their community than they used to be. And what that means is then people dont have some of the same habits of being together on a common project. That they used to. Weve become a more individualistic society. And that, i think, has some spillover effects when it comes to both political participation, but also in terms of empathy, because youre interacting with fewer people on a regular basis. The second thing, though, has to do with how we get information. So i want to throw this out and see what people think. I think a lot of us who have been in politics for a while do see a change from 20 years ago, certainly 30 years ago, where it used to be everybody kind of had the seame information. And we had different opinions about it, but we had the same base of facts. And the internet has accelerated this sense of people having entirely separate conversations, and if this generation is getting all of its information through its phones, that you really dont have to confront people who have different opinions. Or have a different experience. Or a different outlook. If youre liberal, then youre on msnbc and conservative, youre on fox news. If youre reading wall street jurnal or the new york times, or, you know, whatever your choices are. Maybe youre just looking at cat videos, which is fine. The cbs overnight news will be right back.

A price loless piece of American History from the founding of the country has been discovered in england. Its a second handwritten copy of the declaration of independence. Nobody even knew it existed. The only one like it is the original at the National Archives in washington. Charlie dagata has more. Reporter up from the archives and now here just for us, the declaration of independence, in great condition, considering its age and despite what were told is a mouse having taken a nibble out of it at some point. If this is what it is, it is a major find in an unlikely place. One historian called it the discovery of a lifetime. A priceless, handwritten parchment of the declaration of independence. Beyond rare. The only one like it is the 1776 copy kept under the glass at the National Archives in washington. We certainly werent looking for a copy of the declaration like this. Reporter harvard researchers emily snap and Danielle Allen came upon it while searching the globe for every known copy of the declaration. Nobody had an inkling that a second one may exist, so therefore there was no reason to look for such a thing. Reporter they believe it was penned in america in the 1780s, probably commissioned by james wilson. Ill be the man who prevented american independence. Reporter portrayed as a flipflopper in the movie 1776, but a fervent nationalist. And it drills down to the nation. The signatures are in no particular order rather than listed by state as the 1776 copy. Does the american political order rest on a Single National people or on treaties among several states . Reporter the researchers believe the document originally belonged to the duke of richmond, known as the radical duke for the support he gave to american revolutionaries. It was handed down over generations of dukes until a local man handed it into the Records Office in the 1950s. Is this going to stay here . Youre not going to give it up. She makes no excuse for sitting on it for 60 years. We knew we had it, but it didnt have the academic interest and Research Done on it to bring out any of the details. Reporter considering its historical magnitude, it hadnt been treated well. It had even been folded into a small square. But for emily snap, it was a thing of beauty. Being able to go and hold it in our hands, to look at it closely was just extraordinary. Reporter were told the British Library will be conducting a series of tests over the summer to determine its authenticity. While people are invited to have come a look if they want, there the mother involved in a heated altercation over a baby stroller with an American AirlinesFlight Attendant has hired a lawyer, and its the same attorney representing a man dragged off a United Airline flight earlier this month. Part of the scuffle over the baby stroller was caught on video. A passenger who witnessed what happened is telling cbs news s. Kris van cleave has the latest. Reporter it appears according to American Airlines that this all started as a passenger was boarding a flight from San Francisco to dallas and was trying to carry a stroller onto the airplane that was too big to go into the cabin. The airline is getting high marks in how it responded, but it comes at a time when the industry is under a microscope for how it treats customers. The video does not show the mother being hit bit stroller or what led up to the incident. As the camera rolled, she is crying and distraught. Passenger Olivia Morgan says she saw the male Flight Attendant wrestling the stroller away from the woman. It almost hit her little babys head. I said to him, like what are you doing. You almost hit that baby in the head. And then he was yelling at me to stay out of it. Reporter the passenger in the first class cabin then confronted the crew member. Hey, bud, you do that to me, and ill knock you flat. You stay out of this. Reporter with the captain holding him back, the unnamed Flight Attendant dares the passenger to throw a punch. American airlines opened an investigation, saying the actions of our team member captured here do not appear to reflect patience or empathy. We are disappointed by these actions. The Flight Attendants union said neither the company nor the public should rush to judgment. He snapped when he shouldnt have. Reporter an Airline Industry analyst says flight crews work under enormous pressure. Airlines are staffing their planes with the minimum number of required Flight Attendants. Thats not right for the passenger or the employee either. Reporter the mother was later placed on a different flight and given 1,000 flight voucher. Earlier this month, a United Airlines passenger was dragged off a plane in chicago. Oh, my god reporter united was criticized for its response, initially blaming the passenger for refusing to give up his seat and waiting days to apologize. Thats the overnight news for this tuesday.
