irreplaceable. john reilly, you're the best. bon voyage, my friend. >> thank you, john. >> cnn's coverage -- [ applause ] continues right now. russia retreats. a ukrainian counteroffensive in the kharkiv region has now pushed russian forces back as the russian military it appears destroyed bridges, which are vital to ukraine's advances. very good morning to you. i'm john sciutto. >> i'm erica hill. the images in to cnn show three destroyed bridges around kharkiv and officials believe russian troops likely blew them up in an attempt to hold off advances by ukrainian forces. on the infamous snake island, new video appears to show a missile strike on a russian

helicopter. in the eastern donbas region, however, ukraine says its troops are losing a foot hold in luhansk. >> long battlefield and complicated one. this weekend secretary of state antony blinken is headed to germany and france, expected to meet with nato foreign ministers to discuss their response to russia's ongoing war on ukraine. this as ukraine's prosecutor general says that russia has committed nearly 10,000, 10,000 war crimes since its invasion began. this morning a potential glimpse at justice, a russian soldier accused of killing an unarmed ukrainian civilian will go on trial. there he is. let's begin there, cnn correspondent melissa bell is in the capital kyiv. this is a 21-year-old russian soldier, the first to go on trial for alleged war crimes. what do we expect to hear today and is this believed to be the first of many similar trials? >> reporter: quite. as you say, there are so many thousands of documented war crimes now that will be

prosecuted at several different levels. international criminal courts opened an investigation, the u.n. human rights council as well, jim, as have dozens of national jurisdictions and ngos that have begun their investigations into the war crimes that have been taking place here in ukraine over the course of the last few months. what was so unique about today's preliminary hearing and i think this is really the first of its kind is it was a national civilian court that was managing to hold this preliminary hearing to open its first trial into what has gone on here in ukraine since the war began, even as the war continues to be fought. that is quite exceptional. of course, they have been helped again by those many dozens of different investigations, the many journalists that are here in ukraine, documenting what is happening, the technology, of course, that allowed the world in real time to uncover the war crimes as russian troops have retreated from places like bucha and some of the other names that

have become synonymous with war crimes and war time atrocities. this, today, was a civilian court trying a young man, 21-year-old man, a very young man, that's what i kept thinking when i looked at him in the dock, vadim shyshimarin. he's accused of having in the 28th of february, having coming south with his troops, their convoy was attacked by ukrainian forces, they fled in a stolen car. and then as they arrived in a village in the sumi region in the northeast of the country, a 62-year-old man on a bicycle, on his phone, not far from where he lived and vadim shyshimarin was given the order to shoot him, which he did. this becomes the first war crime to be prosecuted. and we had a chance to speak to the prosecutor today who told us the importance of prosecuting even while the war continued was that she hoped civilian deaths could be prevented in those parts of the country where the fighting continues. >> echoes of nuremberg and just following orders, didn't work

there, doesn't appear it will work here either. melissa bell, thank you so much. first on cnn, new satellite images show that russia is now excavating the site of a bombed out theater in mariupol. you may remember this, this is the same one where ukrainian officials believe some 300 citizens who were sheltering there were killed by a russian air strike. the word children could clearly be seen from above in russian. these new images show a crane at the side of the building and trucks parked toward the front. the latest images taken on may 6th appear to show a large hole in the theater's roof, likely the epicenter of the explosion that tore that building apart with all those people inside. >> yeah. this morning ukrainian officials say russian forces are launching artillery and air strikes in mariupol. while blocking ukrainian units near the azovstal steel plant. right now several remain trapped inside that facility last night. erin burnett spoke to the mother of a man defying her pleas to

evacuate. >> translator: i believe he's in there in azovstal. he said he was a paramedic. the guys there need me. i say, you're wounded. you cannot. and he answered, people without arms and legs are wounded. and i have arms and legs, so i'm fine. i know he won't leave his boys in a difficult moment. he won't leave them. he will be with them to the end. and he cannot be taken prisoner. he took an oath, always faithful. >> this morning new cnn reporting that the intelligence community has now launched an internal review of how it assesses the fighting power of foreign militaries. >> that review comes amid pressure from lawmakers who say officials made inaccurate assessments of military capabilities in afghanistan, and in ukraine. katie bo lillis helped to break

this story. what more have you learned here? >> yeah, erica, so the intelligence community is conducting its own internal review of how it assesses how well a foreign military will perform when it is actually thrust into the heat of battle. more than just beyond just counting tanks, but its will to fight, right, like not just the military capabilities, but howan it is facing enemy fire. this comes as there is pressure from the senate intelligence committee who have sent in the last couple of days a classified letter to the intelligence community pointing out that the ic had two pretty big failures in the last year, when it comes to assessing the very question. in afghanistan, the intelligence community appeared to overestimate how long the u.s.-backed afghan military would be able to hold kabul against a taliban assault.

the prevailing assessment at the time was perhaps six months to a year. and, of course, as we saw, kabul fell, the afghan military collapsed really before the united states had even left the country. and now, of course, in ukraine, the intelligence community appears to have underestimated ukrainian military's ability to fend off the russian advance, the prevailing view going into the conflict was that kyiv would fall in three to four days. and, of course, as we have seen we're nearly three months into this conflict and kyiv still stands. the problem for policymakers on capitol hill is that they say, look, had the biden administration had more accurate predictions of both of these instances of how long a foreign military was going to be able to stand up, they might have made different policy decisions. jim, erica. >> good question. what was the effect of this. katie bo lillis, thank you so much. joining us now general wesley clark, cnn global affairs analyst susan glasser as well. general clark, if i can begin

with you, the afghan intel had an effect, right? they overestimated the afghan forces' capability that left the u.s. flat footed as it fell and made the withdraw that much more chaotic. did overestimating the russian military impact the u.s. and west's response to this? would they have gotten more weapons in earlier to help the ukrainians as a result? >> well, you know, the best intelligence about forces comes from u.s. service members who are there working with the forces. in the case of afghanistan, we didn't have anybody out there. and this was the decision made by the trump administration 2018 to stop all the advisers, nobody could go out there. we really couldn't see what was happening in the field. what you're getting from the intelligence community is communications intercepts, talk from various people and so forth, but not seeing the hands on. same is somewhat true in the case of ukraine. we didn't have our own eyes and ears in there, we did have

people in there, but the other thing, jim, about the ukraine situation is that if you're going to do the post mortem audit, you have to look at what we were doing behind the scenes. we did a lot in the last few weeks, three months, four months, when we had the russian plans, we knew they were coming. we put a lot of effort into ukraine and i think we really changed the balance. and on the other hand, we know that putin did not prepare his forces correctly for going in. they had the technology, they weren't -- they weren't prepared. and, of course, who wants to launch a major attack through -- only some intelligence guy who doesn't understand the military. there are a lot of things that -- the intelligence community needs this assessment, but there is a lot of factors that were out of their control. >> taking all that into account, susan, what is the ultimate impact of this investigation? do you see real changes

happening that will in turn lead to better, more accurate intelligence? >> well, i think it is probably a question of, you know, what you do with information that you have. it seems general clark is right that the u.s. intelligence was strikingly accurate when it comes to the question of what the russian plan was and what they hoped to do in ukraine. in fact, there were many naysayers and doubters among european allies here in the united states who didn't believe intelligence that turned out to be strikingly accurate. i think where they had a much harder time is understanding why it is in advance that putin's war plan was going to fail so spectacularly when it came to the battle of kyiv. and, you know, their capabilities didn't match the plan that the u.s. intelligence came up with. and i think that's true both in afghanistan and ukraine, what you see is the question of how does the u.s. frame the

information that it has. how do we assess it? and i think that there is certainly more that could be done. policymakers definitely made decisions on the basis of the idea that russia was going to launch this lightning strike, that it had the capability to carry out, and obviously that didn't prove to be the case. i'm sure that the u.s. would have approached it differently had it had different assessments. >> yeah, and by the way, you make the point, in terms of russian intent and the size of russian forces, the intel assessments were remarkably accurate and right as you say over the doubts of many in europe and elsewhere. general clark, looking forward, given the failure here, does the u.s. need to reassess for instance china's military capabilities and intentions regarding a place like taiwan? >> i think yes, we always have to look at this. i think the near term issue is still ukraine. right now the intelligence community is saying that this

sort of stalemate here, and the question is then, how hard must we work to push more supplies or weapons, more ammunition into kyiv and what is the risk in doing so. so this is the big question. is putin going to use a nuclear weapon and if you give him aircraft, is that going to be the excuse he uses? why haven't we given ukrainians the aircraft they need, the long range rocket systems they need, they have been begging for this for months. and somehow we're holding back on them. we're modulating this. and i hear various descriptions of it. they might strike into russia, they might do this, putin might do that. these are the critical near term intelligence issues and if we get these right, and if ukraine can fend off russia and they checked it, we're a lot safer in taiwan because china's watching very closely whether the united states is timid or more bold in

supporting ukraine. >> yeah. >> general wesley clark, susan glasser, good to have you both with us this morning. thank you. this morning israeli police use batons to beat crowds carrying the coffin of al jazeera journalist shireen abu akleh. she was fatally shot while covering a raid in the west bank. >> atika shubert is in jerusalem. this clash happened before abu akleh's funeral this morning. what followed, how long did this last? what more do we know? >> reporter: well, we were actually at the hospital when the clash happened. they were trying to bring the coffin out and a walking funeral procession. this is what hundreds of mourners who were there wanted. however, israeli police refused to allow the coffin to move forward, as a walking procession, and when they tried to go through, israeli police charged the procession, taking their bah tons and beating at t

some of the pallbearers and the coffin nearly fell to the ground. it was a tense situation. eventually the family took control and said they would find another way to do the funeral procession by car, and israeli police came to an agreement with them, and withdrew. now, after that, the funeral was held at the greek orthodox church in the old city. and it was an outpouring of thousands of people, palestinians coming to pay tribute to shireen abu akleh. remember, she was for many of them almost a member of the extended family, reporting daily on palestinian lives under israeli occupation. for them, this has been a very, very, very close personal death to many of the people here. so thousands of people streamed here. we're now in mount zion cemetery where you may see behind me the burial is actually taking place.

and you can see how many people have come here to pay their respects. jim and erica? >> yeah. that's incredible. atika, good to have you on the ground there, thank you. just ahead here, five republican lawmakers including the house minority leader now facing subpoenas from their own colleagues. if they actually cooperate, if they don't, if they don't, what are the consequences, if any? plus, more than 40% of baby formula is now out of stock nationwide. you know what's in stock, a whole lot of misinformation. a pediatrician joins us with what you need to know and what parents can do. later, we will meet the dog that has become an international hero. there he is, for sniffing out for hundreds of russian mines and explosives left behind in ukraine. i spoke with his handlers, trainer about their life saving and dangerous work. it is a great conversation. you get to meet that little guy.

after months of weighing whether to subpoena their republican colleagues, the house select committee investigating the january 6th attack is taking an extraordinary step. kevin mccarthy and four other gop lawmakers have now received subpoenas after refusing to cooperate voluntarily. >> it comes as the panel is of course eager to find out more information as it heads into these public hearings which are set to begin next month. cnn's evan perez joining us now with the very latest. look, from everything i've seen, and, you know, just my gut, one would guess that they're likely not going to comply. >> i think that's a very, very good guess based on everything we have seen. we know the committee asked these members for voluntary

testimony, asked them to come in voluntarily, and everyone including kevin mccarthy, the minority house leader, said no. so we can -- we can guess they haven't set exactly yet whether they will comply, but we can guess where they will remain. others who are subpoenaed, jim jordan, mo brooks, andy biggs and scott perry. these are people who played a very big part in trying to help the former president stay in office and there is a lot of information that the committee believes they can learn from them. this is an extraordinary, extraordinary request, however. so you can bet that there is going to be some time before we see any of those people appear before the committee. >> there is testimony and there is documents. fbi investigators issued a subpoena to the national archives for access to classified documents trump took to mar-a-lago. made a bit of a story a few weeks ago. how serious of a story is this?

>> this is an investigation by the fbi to see whether classified information was exposed, whether there was a follow -- whether the trump -- sorry, erica, the -- whether the trump in mar-a-lago followed rules that governed the preservation of classified information. and so we know that this is a grand jury subpoena that went to the national archives for them to turn over these boxes of documents that have been retrieved from mar-a-lago. the fbi will look through those with the intelligence community to make sure how, you know what information is in there, how are these kept, who had access to this, the new york times by the way is also reporting that individuals, people at the white house who may have handled some of this at the end of the trump presidency are also being asked to do some interviews. so this could go in a serious direction. we know that the way the fbi

does these investigations, jim and erica, is that they will want to go perhaps -- go to mar-a-lago and see where these boxes of documents were stored, and, again, whether the law was broken in any way in the handling of classified information. >> not the first time there has been questions of trump's handling of that. evan perez, thanks so much. >> thank you. former federal prosecutor and cnn senior legal analyst laura coates. first on the subpoenas here, you heard evan's sense they will not comply. what are the consequences? what happens? >> well, you know, that's the million dollar question here, of course, because there is the of course the right of congress to have the subpoenas and the right for them to expect to be complied with, particularly if you have a committee, that is a congressional committee. we have seen a whole history in modern times about the expectation that those must actually be complied with. more recently there has been people who thumb their nose at

it, which really in a way can delegitimize the validity of the actual committees and their ability to actually enforce them. you have the idea of their rights to have them enforced, but also the idea of the political consequences. as you well know, there is a sort of damocles hanging over this particular committee because the midterm elections is about seven months away. if there is a chance for some reason in the balance of power, the expectation that this committee will go away. and so they got the clock about this notion, the american appetite in terms of their willingness to have been patient since january 2021 to have the information and the idea of the retaliatory notions that have already been floated by people like kevin mccarthy about even subpoenaing members of congress on the democratic side going forward. so there is probably an agonizing decision that has both political consequences and ones in which they thought themselves will we be able to have them enforced in a court of law, in time for those midterm elections.

>> it is fascinating how this decision came about. politico reporting this morning liz cheney was pushing hard for this, right, against some of the other lawmakers who are a little bit more reticent. from your perspective, laura, do the subpoenas, rather, does this add at all to the -- i don't want to say the legitimacy of the investigation, it is not that it isn't a legitimate investigation, but does it in any way bolster it? >> i think it does bolster to use all of the available tools at your disposal to try to compel testimony. if they had simply said we asked you to attend an actual hearing, they could come back later with a talking point that says, well, you know, had you actually subpoenaed me, they maybe would have had a different conversation. by exhausting all of the available vehicles to get compliance, you really do but tress your ability to say we not only have the means, we tried to pursue them. you have this attitude.

the other side of it, you have the political consequences yet again where people will likely fund-raise off the feather in the cap that says, hey, they want to submit to a committee that i said had you just put more republicans on, including jim jordan who kevin mccormccorporal mccarthy, or remove the rinos of liz cheney and adam kinzinger, that would have but tressed legitimacy from the get go. it is a catch-22. you're damned if you do, you're da damned if you don't. if you have in your arsenal subpoenas, why not extend them? you can't -- though it is a political body, the idea of being purely governed by an expectation of a midterm election possibly changing a balance of power would give short shrift to the ability to pursue the investigation in itself. >> quickly, the president now facing -- the former president

an fbi investigation of his handling of classified material. where could this go and what would the potential leave conse legal consequences be for trump? >> the law has been clear since nixon about the requirement that these documents, these papers don't belong in the personal archives of an outgoing president. they're supposed to be part of the so-called public record. you have libraries for that reason. if there is a clear violation of the law, the accountability should be pursued. whether it goes to the actual person who is the subject of it, donald trump, or somebody who was a handler of the information, that remains to be seen. but there is very clear laws as to why we want this in the public record to guard against abuses of power. if there is a violation, i hope for accountability. >> laura coates, always good to have you with us. thank you. still to come here, the nationwide shortage of baby formula prompting concern and a lot of confusion among parents. so what are the options available to you? we're going to look at the dos

concerns about concealed safety problems at a michigan production plant. >> we were aware of this from when the fda had to take its action back in february. with abbott and with the steps in the michigan facility. and we have had a team on this from the fda and interagency process since then. we have been working closely on this issue in the wake of that recall to try to address the attending impacts of that. >> dr. tonya altman is a pediatrician and spokeswoman for the american academy of pediatrics and consults for an australian formula brand not yet available in the united states. good to have you with us. i'm curious, i want to start on the misinformation because there is so much of it out there, what are you hearing from your patients because the white house says consistently contact your pediatrician. >> yeah, you know. as a pediatrician i think that's really my role to help consult with each family on what is best

for their baby. parents are scared now. this will take a multipronged aapproach for us to solve in the united states. that includes by the way supporting breast-feeding and the human milk bank of north america. in addition, i think we're going to have to start accepting help from other countries that already have high quality infant formula that meets the infant formula nutrition act and is already tested and we know -- i know the american academy of pediatrics is recommending in some cases cow milk can be introduced under 1 year of age. that depends on the nutrition your baby is eating. in other cases, toddler formula may be a better option to get that extra iron and nutrition. and, again, you know, as you mentioned, talk to your pediatrician as there are so many brands available, store brands as well, and we can often help parents navigate switching brands to figure out what is best for their infants. >> and that's what can be so confusing. in one camp you have children and in some cases adults who rely on some of these formulas

or nutrition supplements that have to have a very specific kind for very specific health reasons and health challenges. not every baby has to stick with that initial formula that they were given, which to your point is why it is so important to consult with your pediatrician. i know you say you can switch formulas, obviously check with your doctor first. you have other dos and don'ts which i think are important and speaks to theness information out out there. this you make your own formula at home? >> sure. so that's a real ly good point, erica. infant formula is a very precise scientific food product that has been based on decades of research. and you have to have specific ratios of fat, protein, electrolytes and you can't simply buy these individual ingredients at the store and mix them up yourself in your home. the other thing is that it has to be consistent throughout. pretend you're making soup. you can't have too much

nutrition fall to the bottom. that's why we see the dangers when parents try to make their own infant formula. it can be contaminated with serious infections and we have seen historically that to be a problem and too many babies ended up in the hospital because of that. >> to that point about getting the right amount in each spoonful, which is such a great picture to use the soup there. you also say you should never add water to stretch the supply. is it for that reason? >> exactly. when you add water which i know can be so tempting to parents, you mix powdered formula with water anyway, it can dilute the nutrients. you're getting less carbohydrates, you're getting less fat, and the electrolyte ratio is going to be off which can cause serious problems with your infant. >> really quickly before i let you go, there is a lot of back and forth here, finger pointing happening. are you as a doctor getting the information you need about why this plant is still shut down, why it is taking so long to get it back online?

>> you know, i think that's a really good point. and i think this is going to be a big wake-up call to the formula industry in our country that we need better oversight, that we need more options. why does wic only have a contract in each state with one company, right? these are families really in need of infant formula and should have multiple options. i think everybody in the united states takes a look at the different options for their family that will have alleviate the stress on the short supply we have for those families. >> good to have you with us this morning. thank you. >> thank you. coming up next, my conversation with the handler and trainer for perhaps one of the most famous dogs in the world today. a brave one too. petron sniffed out hundreds of russian explosives near the capital kyiv, saving lives. he's such a national icon in ukraine that president zelenskyy honored his work. we'll have details on how that little guy does it coming up.

air bombs. so we have cleared 1,161 anti-tank mines. and over 21,000 kilometers of roads. all kinds of explosive devices, bobby oby traps as well. we have inspected 500 hectares of territory and 7.5 kilometers of gas pipelines. we worked 24/7. >> president zelenskyy presented you and patron with a state award for dedicated service. you're doing life saving work. i wonder how that moment felt for you. >> translator: well, yes, it was very pleasant to receive the award. but that's our job. that's what we do. we make sure that all people can get to a to z without blowing they w themselves up. the state is working and our job is to not let the state down. but nobody thought this would be on such a scale. this is an enormous scale.

we have to work 24/7 as long as we have like. >> patron has become a here yes, ri hero, right? are you training other dogs to do the same thing? >> translator: i'm not training other dogs. i don't have time to train other dogs because we work 24/7. i work with my dog. and i make sure we do our job. and that we make sure people can return safely to their homes after being under such a horrific attack from the russian federation. we have to work nonstop 24/7. there are 41 of us. and 16 vehicles. and that's just in the chernihiv region. >> well, patron is a cute, cute little dog. i hope you and all the teammates you're working with are safe and i hope he's safe too going forward. thank you. >> translator: thank you very much. we are trying to make sure to avoid injuries.

>> all right, my favorite interview of the year, by far. >> without question. it is going to be hard to top that. he's amazing. i love the story of how he, you know, he got this job for his son, but just started taking him to work. thank goodness he did. >> he was a pet. i've seen bomb-sniffing dogs around the world, you see them at thor at. that's a serious job, requires a lot of training. he's saving lives. patron, little dog, as you may have noticed, nine pounds, four til kilograms. >> that's it. >> most land mines need about five kilos of weight to set them off. so patron has a built in protection against this stuff, which is another advantage for him. >> i love that. i love that. i heard him at the end saying -- one of my few ukrainian words i picked up, thank you. >> you saw his tail wagging. >> i feel like we could talk about patron all day and we would. we'll get yelled at.

tweeted again he's still committed to the acquisition. so which is it? >> god, the question. so that first tweet sent shares plummeting. i know you were just checking how twitter shares were doing. we look at this back and forth. my question is was he ever serious in the first place? >> right, is he serious now? nobody knows. the stock is down 10% this morning because some investors already skeptical of musk are skeptical he's going to go through with it. here's what musk said basically overnight that the twitter deal is temporarily on hold and linked to a story from reuters that's 11 days old about twitter's number of bots and spam accounts. so he's saying he wants to confirm this that spam and fake accounts do represent less than 5% of research. bots, spam accounts, fake accounts are a plague on the

site so seemingly might be using this old article, 11-day article as a pretext to back away from the deal. maybe he wants a lower price for twitter. that ultimately might be what it's all about. as you said twitter an hour ago still committed to acquisition, those are his four words trying to reassure investors. they're already stressed about musk and now even more. >> markets changed a lot since his offer. twitter stock is down, tesla stock is down. so i'm curious if this were not to go through what happens? these big questions for twitter. >> if this breaks up he does pay a $1 billion fee. he can certainly afford that, but he may not want to pay it. he might be trying to a find a way to get a lower price. if this happens there is no buyer out there. the board went out looking for a

buyer and only saw musk as an option. but i think musk, he does seem very interested about free speech. he seems to enjoy this issue of social media. he seems to want to own it. maybe he's finding it more fun to make it seem like he's in charge without being in charge. >> looks like fun but maybe it's not. the nitty-gritty day to day not so fun. still ahead, an exclusive report. cnn team on the ground in ukraine tracking evidence of potential war crimes committed by russian soldiers. it is a fascinating and important investigation. you won't want to miss it. it's coming up. ...so you feel c, night after r night. for a limited time, save up to $500 0 on select tempur-pedic® adjustable mattress sets. ♪ ♪
