Transcript for Trump meets Kim Jong Un at Korean DMZ
Good morning, and let's get straight to breaking news overnight. A historic encounter just hours ago at the dmz, the border between north and South Korea. President trump shaking hands with the north Korean leader Kim Jong-un. Who accepted a last-minute I havation from trump extended over Twitter. The president becoming the first. The two leaders met behind closed doors for more than 30 minutes. They didn't cut a deal to denuclearize North Korea. But they did agree to restart stalled talks. We have team coverage this morning. George Stephanopoulos is standing by. But we start with Jon Karl who's on the ground in Seoul, south Korea. Jon, good morning. Reporter: Good morning, whit. With one dramatic gesture, president trump became the first American president to set foot in North Korea and also the first to set up an impromptu meeting with a north Korean dictator via tweet. At first, the meeting seemed well choreographed. President trump walking from the south Korean side. Kim Jong-un from the north. Good to see you again, Kim said, never thought I'd see you here. The handshake across the border. Then the step into North Korea, a first for an American president. And it happened just 32 hours after trump tweeted the invitation to meet at the border. As they walked back to the south Korean side -- It's a great day for the world and it's an honor for me to be here. Reporter: Another rarity, Kim Jong-un speaking to reporters. President trump just walked across the demarcation line, he said, that made him the first U.S. President to visit our country. Tremendous positivity. Really great things are happening in a lot of places. But, we met and we liked each other from day one and that was very important. Reporter: As they walked toward the so-called house of freedom, chaos. Security guards at first blocked the U.S. Press. And then, a scramble to get the American reporters inside. That's the new white house press secretary Stephanie Grisham, elbowing and shoving a north Korean security guard. More chaos inside the meeting. And words of diplomacy. It was an honor to step over that line and I was proud to step over the line. Reporter: The two leaders then met behind closed doors for about 40 minutes. Followed by another chaotic scene, as trump walked Kim back over to North Korea. There's no question today's meeting was an historic first. But after two summits and one impromptu meeting, North Korea's nuclear program remains fully in place. President trump announced there will be a new round of talks, some at lower levels, with the aim of stepping up an agreement that would finally add some substance to this incredibly powerful symbolism. Whit. Truly an extraordinary scene. Jon, this was classic trump. The master showman in his element. You were there for his two previous meetings with Kim. How big was this moment for president trump? Reporter: Whit, in terms of sheer performance this may have been trump's biggest as president. Keep in mind, North Korea is known as the hermit kingdom. North Korean leaders are famously reclusive. The idea of setting up something impromptu is really unheard of on the border. But as I mentioned the north Korean nuclear program is fully in place. There's not been any progress towards of an agreement in terms of scaling it back. The big question is whether this symbolism, the big gamble that the president has made, whether or not it would lead to some kind of agreement to actually end that nuclear program. The important question, Jon Karl in Seoul, South Korea for us.
