top of the hour. i'm jim sciutto, and this morning an unprecedented visit to the war zone. president biden made a trip to

k kyiv to show support for ukraine without a large military presence. without that military presence, of course, it is different from other presidential visits to afghanistan or iraq for instance, and the air raid sirens as biden is walking side by side with volodymyr zelenskyy and it is the first trip to the country since the russian invasion. he made the decision friday to make this visit to ukraine, and the president had invited him prior, and he was informed hours ahead of the arrival there which tended to deconflict to make sure that russia would not fire on kyiv while he was there. in a news conference this morning, there was a new round

of sanctions including another $500 million assistance and more weapons, and biden's trip gets them closer to victory. >> freedom is priceless. it is worth fighting for, for as long as it takes, and that is how long we will be with you, mr. president, for as long as it takes. >> for as long as it takes. kaitlan collins is in warsaw in kyiv, ukraine, and first to you, kaitlan, and we know that the biden administration messaged russia to deconflict and ensure the president's safety there, and this is quite a decision by the u.s. president to visit the war zone, and tell us how it came about. >> yeah, they did alert the

russians that the president was going to be in ukraine, and that is of course, because there are many russian forces on the ground, and they did not want any safety issues there with president biden's trip, but overall, it was a risk for president biden to go to ukraine and this is why he has not gone in nearly a year invasion on the way, but what his national security adviser told the supporters is that the message that they were able to send was that it was worth the risk for president biden to go there, because they wanted to show solidarity with ukraine and not the u.s. support of ukraine, but affirmation of it, and that is support that is going to be there as long as it takes, and of course, what that means, and what else the u.s. may send to ukraine to help them to fight this war as they have been doing so far, but in the visit, he went and he was strolling

through the sunshine as you heard those air-raid sirens going off in the background. and also, as he was announcing half a billion of aid that the u.s. is sending to ukraine, it is half a billion sending other types of weaponry, and it did not include anything new of what we have seen from the reports that he said on the ground, and no jets, and really it was the trip in and of itself that the white house says is notable. they have been planning it for months and weighed the risks, and he made the call last friday as he huddled with the aides to make that trip. he boarded air force one in washington before heading to kyiv and then to warsaw. it is a 10-hour train drive to the border as you know, and jim and clarissa knows, it is a long

ride and drive for the president to make, but it is one they felt was worth making this close to the anniversary. >> no question. clarissa, you are in the square where biden and zelenskyy met, and tell us about the symbolism of where they met, and how the ukrainians are responding to the remarkable visit. >> yes, jim. we have been seeing the ukrainians coming out all afternoon as they heard that the president biden had been here, and they havehave been pouring on the st. michael's church here on the side of me, to look at the wreath that was laid with the american flag on it, and for them and the ordinary people here and the leadership here, this is a big deal, and something they had hoped for, for long time. we know that president zelenskyy had invited president biden a number of times to visit, and he

said himself today as the two presidents as they were meeting, he said with this conversation, ukraine is one step closer to victory. that speaks to the effect, to this anticipated effect on morale. it has been a tough winter here, jim, and the fighting in the east is grim, andle is of the highest rates of the ukrainian casualties and still very high casualty rates as well, and people have been living in the cold without power, without running water, because of the ruthless campaign of russia targeting the infrastructure, and to see the president of the united states come on this unannounced trip at this tense moment and make this hugely symbolic tour of st. michael's, and i think that it spoke to people, and it gave them a morale boost, and made them feel that ukraine can win this war with one major caveat which

president zelenskyy mentioned himself which is the discussion of heavier weaponry, and long range artillery and fighter jets. in the short term, the focus is getting ukraine more ammunition, which president biden said it is forth coming, and it is a huge issue with the ukrainians and also reporting from cnn's reporting for the requirement that they need to produce it at that pace. so definitely a significant moment here, and definitely a day that the people will be talking about for quite some time. extremely heavy security. we were up here as it was happening, and visited multiple times by soldiers who told us that we could not be near this balcony or near this window and we could not have our camera pointing out in this direction and at one point they were using

lasers to point in the faces of journalists who were trying to get a view. and we were crouch at one point, because it is a wide open space, and you imagine for the security services how difficult it was even with that foray of difficult forces for the president to get in and out fairly quickly without any incidents. >> they would not want to take anymore chances on the chances of visiting the capital during war. and here to discuss is doug brinkley and retired general waxman and also our special correspondent. and so, i want to start with

you, doug brinkley, a president in a war and no american forces on the ground, and how significant? >> it is extremely significant. i go back in history to roosevelt and churchill when they had to sneak off in the dead of night when they had a body double to go meet churchill off of the coast of newfoundland and then of course all of the meetings in world war ii. and then, zelenskyy has been called churchill of our generation, and biden going there today, it is going to be a moment for the history books. it is like when john f. kennedy went to berlin and gave a speech at the height of the war, and this is the height of the western allies and biden did something really heroic. >> yeah, a new frontier of the east and the west. jonathan wakro, and tell me,

because i would not want to be in charge of the president's security here, and tell us what would have gone through keeping him safe in a war zone? >> well, jim, this trip is unprecedent because the presidents have gone the war zones and hostile environments, but the planning and execution for this specific trip is unique. it is deviating from the standard model that the secret service has applied in the advanced planning. what i mean is that in the past, some of those trips that are brought up from brinkley, we see a reliance on u.s. military support. specifically, u.s. military support on the ground. we didn't have that. so what is the secret service going to have to do? go back to the basics and have a detail threats a assessment an then prioritize them and then

manage them. and this is not to eliminate them, but to manage them. and it is who can they trust on the ground, because we don't have u.s. counterparts. at the end of the day, jim, they are thinking of three things, tactical, medical and relocation situation for the president of the united states when you are not tethered to u.s. military assets. >> we did hear part of the small team a medical team in case of that eventuality. >> and brigadier general, you have commanded troops in a wartime, and this is a difficult point there in wartime, and the losses on the eastern front are horrific on both sides frankly. what does it mean if your view for the ukrainian forces fighting to see the u.s. president come visit? >> it is enormous, and if i could quickly add on to my colleague's statement about churchill and that era. president biden's visit harkens

back to edward r. murrow's statement that this is london in the blitz air raid sirens going on in the background and it is surreal to see the president there with similar circumstances in a beleaguered wartime capital. the war, itself, it is grinding out. while the russians have mass, they don't have quality. but as the old line that quantity has a certain quality of its own. the ukrainians are putting up a great fight, and i believe, jim, there is brittleness in this mass and within the population. as resolved as they are. this visit just adds to the determination and the will for

ukrainians to fight that matters and adds in immense ways to the fight on the front which is hard. >> doug brinkley, this is already in effect a proxy war between the west and russia given the amount of weaponry that the u.s. and the nato allies are sending to ukraine. we learned over the weekend from secretary blinken that the u.s. is seeing indications that china may make a move that it has not yet in this war which is to pro1r50id leth-- provide lethal munitions to russia. what would that do to lengthen the war? >> it would lengthen the war. i worry that there is no exit strategy here for putin. if the only lifeline is to china, and if he doesn't get that, he is stuck. there is not track to diplomacy

and there was a thought that turkey could come in to do some, and we are in for a long haul, and if china enters, this is global cold war of unprecedented dimensions and unprecedented dangers. >> a proxy war. so general, brigadier general, one category of weapons going to ukraine and that is tanks, and then the next category is f-16s and is that phenomenon overdone, and when i speak to experts, they are skeptical that is what ukraine needs right now. >> i think that the f-16ed certainly would be a significant addition, though it is going to take time to train the air crew. the ukrainian air force has done

remarkably well, but it is tired with the worn out mig 29s, and the 16s and missiles will add a lot. and at this point, the russians have been so vicious in the aggression, anything along that type including long range missiles are completely justified. no, i think that they won't be per se a game-changer, but it is going to make it a whole lot harder for russians to get too close with the cruise missiles and other capability, and the f-16s have a very good ground attack capability. >> we will be watching closely. brigadier general peter zwack and doug brinkley and david, we are grateful to have you join us. >> and now, on a new scale of

the crisis a documentary is sharing the stories of thousands of ukrainians and particularly the children whose lives are torn apart by this. we will be joined by him. and ohio residents say that since the toxic derailment of that train near their homes. they are now going to get some antss. we are live e near palestine, ohio. forever. the subway series. the greatest menu of all time. -what's he doing? -he's cleaning the trash cans. oh, boy. meeting a new young homeowner for the first time is a unique challenge. -so you think you can help? -i can try. hey, what you doing? oh, just cleaning my tra cans. wow. it's important to build trust. see you put your address and phone number on here. well, you can never be too safe. with trash? progressive can't protect you from becoming your parents, but we can protect your home and auto -when you bundle with us. -don't look at the hedges.

security staff involved in the planning. we'd like to hear more. >> yeah, jim. we have been talking about all of the details of the secret planning that has to go into such a meeting with such risks as this one. we have amanda slote here who is the national security adviser here on the ground, and obviously the president is on the way, and this is hard decision for any president to make, because there is such risks that go into this, and what were the top concerns that you and your team were considering planning this trip for president biden? >> well, the top concern is obviously security. president biden has made it clear that he wants to go to ukraine. it has a special place in his heart back from when he was vice president, and he has been actively involved in ukraine and welcoming president zelenskyy to the white house twice, and multiple phone calls, and he felt ahead of the one-year

anniversary to go make the trip to stand side by side with the president to show sustained american support for ukraine. the team was looking at the risks involved and the president decided it was a calculated risk and one he was prepared to take. >> he only had a few hours on the ground with president zelenskyy, so you want the through lines and the top points, and what is the main thing that he wanted to talk to president zelenskyy about? >> it is an opportunity for them to follow-up on the conversation in december and update on where ukraine was in terms of the military planning on the ground, to discuss the needs of ukraine of the military assistance and the assistance that we have forth coming and talk about the needs on the economic support side and the energy assistance size and the breadth of the relationship. as the president says, nothing

beats face-to-face engagement, and he wanted to have that opportunity today. >> he announced a half a billion new assistance, and he mentioned some of the things included in thata and he did not mention fighter jets or longer range missiles that zelenskyy wants. none of is that in the package? >> the package is to provide ukraine with the capability for the near term fight which is expected to be artillery and munition and continued air defense. >> and what i have been learning is that the countries who have the fighter jets that ukraine wants and not just the f-16s, be t to train them now so there is not a lag time? is that something that the u.s. would do? >> some countries are planning to start training them on the

planes, and we have expressed interest in training them on the ground offenses. the two presidents had a chance to exchange plans for security assistance, and i don't have anything to share, but they did exchange ideas. >> so president zelenskyy did bring it up? >> yes, the ukrainians have made it clear publicly and privately about what they need, and this is a good opportunity for president zelenskyy to relay his requests, and for the president to relay his thoughts on additional assistance. and they will be notified the u.s. ahead of time. >> and how did the notification to the russians go? >> we did send a notification to

the russians, and i cannot let you know all of the channels, but i can confirm that it was done. >> can you tell us what president putin said about the visit of the u.s. president to ukraine? >> he will be giving his speech, and it is going to be historic, since it was a year here last time, and chance for him to speak to the people of poland and ukraine and the american people about our continued robust support for ukraine and the rock solid security to our nato alliance. >> we are in poland and this is a big aspect of the trip that he is taking, and really the role overall in ukraine has changed the way that poland was viewed before this invasion happened, and how does it affect president

duda's relationship with president biden? >> i believe it is strong. he met here a year ago with the president duda and he will have an opportunity to meet with other polish official, and to your point, poland has stepped ip and providing a large amount of secure assistance, and defense spending and they serve as a hub of humanitarian assistance providing for ukraine, and of course, we did a major energy deal with poland in the last several weeks as well, so we are stare strengthening t bilateral ties on the energy and defensive side. >> i know that there was a lot of going on behind the scenes and thank you for that

information. and so, yes, amanda did confirm he brought up the f-16s, and that was not something that is part of the package. and so now, the residents in ohio will be getting medical help and soon. we are going to be live from east palestine, and that is coming up. hi, i'm michael, i've lost 70 pounds on golo. i spent thousands on other diets that didn't work. on golo, ipent a couple hundred bucks and got ck down to my high school weight. you're not gonna believe this thing is possiblbut it is.

tomorrow the ohio department of health is opening up a clinic in palestine, ohio, where some residents are reported feeling sick after the toxic train rederailment, and now the company's ceo says he is in favor of a controlled burn that released some of those chemicals. so jason carroll is there, and so, how serious are the symptoms that the local residents are reporting there? >> well, it is depending upon who you are talking to, jim. this is what some folks are going to be finding out here at the church tomorrow. this is the site of the clinic, and some people have been road loading some things there in the doors here, and if people are experiencing some symptoms, they can come here to be examined by experts. the ohio governor says it is being done out of an abundance of caution. >> reporter: two weeks after the

norfolk southern train derailment and the controlled release of chemicals by the company that followed, the residents in the east palestine, ohio, are increasingly worried about what is in their air, water and soil. >> when we are thinking about the chemicals that we know that have been released, they are known carcinogens. vinyl chloride is a known carcinogens, and we have to look at the impact to the vulnerable citizens. >> reporter: and this is now shared in the neighboring state of pennsylvania. >> look at the chemicals and the colors and it has a butane smell to it. >> reporter: the governor of ohio says that the air quality tests in more than 500 homes showed no detection of contaminants, and they say that public water is safe while private well water users should stick with the bottled water for

now. and this spill is still causing uproar and criticism directed at norfolk southern. >> everything that has happened here, all of the cleanup, the drilling, the testing, the hotel sells is all on norfolk southern. they caused it, and no question they caused it with the derailment. >> reporter: in addition to the thousands of fish found dead, cnn is learning that two horses are being treated for smoke inhalation after the controlled burn by the department of agriculture, and standing by their decision, the ceo of norfolk southern says that the burn is the right thing to do. >> we did what we needed to do in order to prevent an uncontrolled explosion. >> reporter: the government has deployed experts to assess nonhealth concerns, and the people in the community have been reporting rashes and nausea, and the cdc is going to send a team to assess the public

health need, but that is not stopping what some are calling the biden administration's slow response disaster. saturday, pete buttigieg responded to the ceo saying that major derailments have been called for reforms and vigorous resistance by your agency and this must change. and jim, the residents can start to make appointments today to come out to church tomorrow if they feel it is needed. so what is on the ground here, it is clearly the large disconnect between the folks here on the ground who do not trust what the government is saying about the air and the water, and the government saying that the water and the air is safe. jim. >> a lot of skepticism there. thank you, jason carroll. and president biden making a

trip to the active war zone, we will zero in on the people who are watching his trip and tens of thousands of young ukrainian refugees who have had their lives torn apart, and the young filmmaker who has been documenting situation will join us. >> i do not want to come back until it is over.

russia's invasion forced 8 million ukrainians flee their homes and the largest refugee crisis since world war ii. many of them children torn away from their families and experiencing terrible trauma and loss. a new documentary is focusing on teenagers making a new life in poland, next to ukraine, and here is a sneak peek. >> it is one second, and i was awake, because rockets were crashing in our part, and it changed my life. my classmates asked how it was in the beginning. in the beginning, i explained how i got to poland and how i feel when the rocket was crashing.

i go in car and interstate. the city was in on fire. in one moment, everything can change, and everything can end. >> true words. join us is the director of "don't leave me behind" the young ukrainian survival and it is going to premier tomorrow night on mtv. welcome, nathaniel. >> thank you for having me. >> and watching the people flee by the thousands, it evoked images of world war ii, and you documented so many of them to the year end, and how are they doing? >> they are -- and it is complicated. they are doing well in some regards and more resilient than ever, and this war has done anything bolstered the national identity and they are ukrainians

and not going anywhere. >> many of them are separated from their fathers, because the war aged men which is defined broadly in ukraine have to stay behind to fight, and what is that separation like for them to be separated from their fathers and how is that impacting them? >> it is really, really diff difficult, and one of the central focuses of the film, because we are looking at the kids who have witnessed destruction by combat, and the separation of the families and they have not communicated with their fathers for months on end, and it is traumatizing. >> and many of them have lost their fathers sadly. >> yes, the scale of casualties has been one of the biggest elements of this war is just the scale of loss on the front line and a lot of their fathers are there. whether it is the confirmed loss of life or just the lack of communication in general. i mean, once you are on the

front line, you are in a place where communication is monitored, so there is no capacity to have a call, have any sort of connection whatsoever without giving away your position. >> having covered a lot of wars myself, i am struck how we focus on the immediate casualties of the war, and then we forget about the ripples of the casualties, the ptsd and the traumas to families and i wonder how the neighboring countries are dealing with it, because we saw the outpouring of welcome to the refugees, and a year later do they get the same welcome? >> it is tricky, because there is not a coherent system in place, and that is what i want to do with this film is have the countries re-evaluate the response to refugee who are in

flux like this. and there is not a unilateral way to handle these refugees, and there is nothing completely comprehensive about it, but they are doing their best. >> they are doing their best, but one thing that comes across is that a lot of the kids remarkably maintain a lot of hope in the midst of this. how do they maintain that hope? do they see or are they seeing or hoping for a light at the end of the tunnel here? >> sure. you know, the film tells the story of two young extraordinarily resilient and powerful young women. we focus on a number of people, but two in particular, and they process the trauma differently, and they see the light at the end of the tunnel in different ways. sasha volunteers and gets involved with the activities and expresses her own emotional processing by dance and hosting

dance classes with young refugee kids, and our other subject is through writing, and goes to heal through creative outlets, and everyone is going to process differently. >> and so some of them have a tough decision of when to go home, and many of the refugees have returned home since the start of the home, and particularly in the western part of the country and going back to the capital kyiv, and oftentimes it is the adults and not the children, but are families struggling with that decision right now? >> e, iyeah, it is a major part the film is now that we have been ripped from our country and families, what do we do next. so it is going back to the feeling of national unity and community on the global level for ukrainians. this war has ripped them from their homes and their cities are

destroyed is or severely damaged and splintered across the world, but never a bigger sense of we are ukrainians and this is who we are. we are not going to be silenced and splinter and so we will go home, and the question is when. the recurring theme is kids saying things like, i want to take my new education that i am learning in this new country and take it home with me. right. so there is a feeling of let's use this as an opportunity to grow, and return home and build what needs rebuilding. >> and then what will they return home to. nathaniel lezra, thank you for doing this film. >> thank you. appreciate it. this morning, king charles met with recruits training in south england and britain had promised to train some of the ukrainian pilots on the jets, and that is a key, because they are one of the largest weapon suppliers, and earlier president
