World. That story is coming up. Were live in atlanta. Im natalie allen. A writer back there is really excited about it. Im George Howell from cnn World Headquarters in atlanta. Newsroom starts right now. And we begin with the breakthrough between south and north korea. State media are hailing it as historic. Kim jungun appeared affable and relaxed as he crossed into the south for a day long summit with President Trump moon jaein. At the conclusion, kim and mr. Moon vowed to formally end the korean war and to denuclearize the peninsula. Donald trump also tweeted his approval, he wrote korean war to end. The United States and all of its great people should be very proud of what is now taking place in korea. He also had this to say. I think i have a responsibility. I think other president s should have done it. I think the responsibility has fallen on the shoulders of the president of the United States. And i think we have i think i have a responsibility to see if i can do it. And if i cant do it, it will be a very tough time is for a lot of countries and a lot of people. It is certainly something that i hope that i can do for the world. This is beyond the United States. This is a world problem. And it is something that i hope that im able to do for the world. The u. S. President taking the credit, but there is still room to go here. Lets bring in Paula Hancocks who covered the summit. Thank you for your time today. Look, the day after this historic meeting between the leaders of north and south korea, what is the overall sense there in seoul for people who watched on about what they witnessed and where things go from here . Reporter i think there is a certain amount of optimism basically because the optics were just so powerful. But there is also optimism because many people in south korea want to believe that this could market change especially when you consider where we were just a matter of six months ago. The tensions were incredibly high on the Korean Peninsula last year. The intense Nuclear Missile testing was unprecedented in north korean history. So i think the fact that we are seeing these kind of images that the leaders of north and south korea embracing and smiling, stepping over on the mdl, the military demarcation line, into the south and into the north with the south korean president and then back into the south, these kind of images are extremely powerful. And certainly i think for Many South Koreans they will be relieved that were talking when potential peace and not missiles. Having said that, there is still a huge amount of sceptickeptici because South Koreans have been here before. But the optics are good and you shouldnt take away from the fact that this was an extremely well planned show. Denuclearization of the Korean Peninsula and a vow to end the korean war. Together on the south side of the divide, president and Supreme Leader dlifsh teliver t aspirational decree, announce what would have been unimaginable just 12 months ago when the north threatened to turn seoul into a sea of fire. Translator today we have agreed that a complete denuclearization will be achieved. That is our common goal. Reporter this historic moment after a day made for division and the history books. Kim jungun gripped president moons hand and steps over the simple concrete line that represents a korea divided for generations. Handinhand they take a symbolic and unscripted step into the north. Kim is now the first to travel to the south since the armistice in 1953. Translator i came here with a mindset that im standing at the starting line of the new history of the north south relationship. Reporter a unified Korea Remains a long way off. For now it is about guaranteeing survival. The north needs relief from biting sanctions. For the south and the watching world, it is the promise of denuclearization. But an afternoon walk in a dmz garden offers the leaders a chance for private discussion. Stern faces betray an intense conference. Pageant friday returns as the men meet their wives for a banquet, the menu sourced from across the peninsula offers a reminder of what unites the two before millions across both koreas and around the world wait for what will happen when donald trump comes to the table. It is interesting also to see how state run media has covered this. There are a number of news articles already about what happened, about the tree planting, about how they stepped over the mdl of course mentioning the fact that president moon also stepped into the northern side of the dmz. So it is a very different tone that were seeing from north korean state run media which means that it is a different tone that the north Korean People are being shown now. Not speaking of a puppet government as they often did when it came to south korea as they dont believe the government is legitimate, but talking about president moon jaein. So were seeing a sea change as well in what the north Korean People are being told. That is really insightful. Thank you for pointing that out. And thank you for the report, paula. Well stay in touch with you. Before the summit ended, we heard even more from the south korean president and his north korean counterpart about the peninsulas future. But they were short on specifics about how peace would be achieved. Translator we believe that the dark shadows that gloomed over the Korean Peninsula, the glooming of the war, have been removed and we have a path to peace. We are able to determine the fate of our people on our two sides. Translator the meeting today and results we were able to weave together are only the beginning and it will be the tip of the iceberg to what we are going to be able to achieve in the future. The u. S. Secretary of defense is expressing high hopes about dealing with north korea. But general james mattis told reporters at the pentagon he doesnt want to assume anything at this point. Listen. I dont have a crystal ball. I can tell you we are optimistic right now that there is opportunity here that we have never enjoyed since 1950. So were going to have to see what they produce. But that is going to take diplomats working and im not going to calculate in advance anything. It is historic, but a lot of questions. Lets bring in jasper kim to talk about it, director of the center for conflict management live from seoul. Thank you so much for your time today. So a great deal of hopefulness around this summit, but lets talk about these vague terms and statements. First the very general agreement signed by the president moon and chairman kim to end the korean war. But given how short in detail it is, how difficult do you think it will be for these leaders to agree to specific terms . Well, george, it all depends on trust and chemistry. These two things go handinhand especially at the very top leadership command change as we will see here in the next stage with kim jungun and donald trump. I mean all these agreements, whatever form they may come in, the 1994 agreed framework, the 2000 framework, 2007, theyfairl they have broad language upon which the leaders can interpret and extrapolate what they want and take that home to their constituents and claim wins. Is so when kim jungun meets donald trump, they will have to barrel down on these issues. And i dont think that it will get into granular level of detail, but it will get into more detail, that is a necessity. And this is where the elected leaders on the u. S. Side and south korea, that is their job, to take it past the finish line. Again these hopeful images, but as the saying go, the devil is always in the details around the word denuclearization. What might that mean for north korea, how that might be different for south korea or for the United States . Well, that is a great question. I think if the definition of denuclearization is broad based enough as these agreements tend to be if you parse through the language of past agreements between north korea and other parties, then you can interpret whatever you want in it and that is the virtue of an agreement that is very broad. Of course on the flip side of it, it is not detailed enough so that it doesnt have all the steps and verification processes and the parties explicitly stated by name. So you can only get what you can take from it. These two leaders, kim jungun and donald trump and kim jungun and moon jaein, they only have a limited constrained amount of time to speak about things. So if they come away with any type of agreement in form that they can hail back to their respective constituents, i think if they said we got to yes, that will be a success metric that has been met. So this meeting between these two leaders now in the history books. All eyes ahead now to this possible meeting between kim jungun and the u. S. President donald trump. Did fridays meeting at the dmz lay significant ground work for that and what do you believe north korea will have to do in the weeks ahead of it . Yeah, well, i think the answer is an emphatic yes. What these two leaders from both koreas, i think if anything, they met the expectations probably exceeded it and the up side the down side is that the next iteration of this meeting between the u. S. And north korea, from the u. S. s perspective and Donald Trumps perspective, he doesnt want to be upstaged at all. He doesnt want the opening act to be greater than the act itself. And that is how he sees things as a former media person. So he might be concerned about that and he will try to upstage what has just happened because the visuals and optics, the stage craft of it all, something that Steven Spielberg couldnt have choreographed to that level. And in terms of moving forward, it is really unclear what has to be done, but i think it all depends what happens when kim jungun and donald trump walk into that room and they basically sniff each other out, can i trust this person. That is the critical issue. And the more they trust and the more detailed they will be in the agreement if there is one. But again, you cant underscore it more the optics will certainly be important. And what could derail those optics . The details. Well have to wait and see. Thank you so much for your time jasper kim. He makes a good point. Maybe we can get Steven Spielberg to help orchestrate it, make it look good. All right. Coming up here, new developments in the russian meddling investigation. Remember that russian lawyer from the trump tower meeting with Trump Campaign officials . She is apparently not who she said she was. Well tell you more about that ahead.

Republicans on the House Intelligence Committee issuing their report saying there was no collusion between the Trump Campaign and russia. And there is new information on that russian attorney who is now at that Infamous Trump tower meeting with the Trump Campaign officials. Jim sciutto has details for us. Reporter the russian lawyer who met with Trump Campaign officials in 2016 touted as having dirt on Hillary Clinton now admits that she has closer ties to the kremlin than she previously disclosed. In fact, she calls herself an informant for the russian government crititing new email New York Times reports that Natalia Veselitskaya someones worked with the top prosecutor, i am a lawyer and i am an informant, she told nbc news. Since 2013, ive been actively communicating with the officer h. Office of the russian prosecutor junior. Last year veselnitskaya said just the opposite. Have you ever worked for the russian government, do you have connections to the russian government . Translator no. Reporter the trump tower meeting is of interest to special Counsel Robert Mueller for two potential reasons. First, to see if there is evidence that the Trump Campaign colluded with the russian government during the campaign. And second, to see if the president attempted to obstruct justice buys helping to draft a misleading explanation for what was discussed in the meeting. Ranking democrat adam schiff said the lawyers revelation makes russias intentions clear clearer. What is the importance of this admission that she wasnt a private attorney, but working in effect for the russian government . It corroborates of what we have seen of veselnitskaya, of her contacts within the russian government as well as her persi persistence in terms of putins top priorities, this is someone on working on behalf of the kremlin. Reporter notably schiff says that veselnitskaya reached back out to trump aides after trump won the election. Youre saying it has the impression of a quid pro quo . It certainly does. Certainly the russians thought that they had reason to believer after the campaign that they now might get the help that they sought in that meeting at trump tower. Reporter the revelations come as republicans released a redacted report concludesing that they found no evidence of collusion between the Trump Campaign and russia. The republicans however did fault the campaign for meeting with the russian lawyer saying it, quote, demonstrated poor judgment. And they criticized trumps repeated praise for wikileaks. Wikileaks, i love wikileaks. Reporter stating it found, quote, the Trump Campaigns periodic praise for and communications with wikileaks a hostile Foreign Organization to be highly objectionable and inconsistent with u. S. National security interests. President trump braispraised th report. It was a great report. No collusion which i knew anyway, no coordination, no nothing. Takes wit it is a wupitc witch hunt. Reporter in other findings, Michael Flynn contacted the russian government earlier than previously known. Meeting with Sergey Kislyak at his residence, a meeting requested by either flynn or his son. The report says that the meeting was later described by general flynns son in an email to the Russian Embassy as very productive. Also in 2015, trumps personal lawyer Michael Cohen and russian American Business associate felix sadr were involved in efforts to cement ties between then candidate trump and russian president vladimir putin. During an email exchange about building a trump tower in moscow, sadr wrote to cohen, if, quote, putin gets on stage donald for a ribbon cutting, donald owns the republican nomination. And more revelations contained in the democratic version of the house intelligence report, evidence of communications between russians involved in that june 2016 trump tower meeting, reaching out to the trump family, and associates, days after trumps election, including discussions of possible business deals, certainly information, certainly communications that the special Counsel Robert Mueller would be asking questions about as well. Jim sciutto, cnn, washington. Thank you for that report. And we saw the german chancellor Angela Merkel there in jims report. She is the latest european leader to urge the u. S. President to stick with the iran nuclear deal. The two spoke at the white house friday and mr. Trump insists that it is a bad deal for the u. S. And that no matter what the u. S. Takes a hard line on Irans Nuclear capabilities. I dont talk about whether or not id use military force. It is not appropriate to be talking about. But i can tell you this, they will not be doing Nuclear Weapons. That i can tell you. Okay . They wont be doing Nuclear Weapons. You can bank on it. Chancellor merkel admits the agreement is anything but perfect, but that it is important First Step Towards curbing Irans Nuclear ambitions. And is essential for europe. Translator all of the region obviously is of prime importance to us. Because it is not 1,000
