>> i'm pamela brown in for jack taper for this special edition of "the lead." we honor the fallen men and women who died serving their country. our coverage continues now with jim acosta in "the situation room." >> happening now, a new outpouring of grief and anger as funeral services begin for the victims of the texas school massacre. and new evidence emerges about the delayed police response. an audio recording appears to confirm that a dispatcher told officers about a 911 call from a child during the shooting who is, quote, in a room full of victims. >> also, ukraine reports nonstop russian shelling with new attacks at maximum intensity in the east, just hours after president zelenskyy visited the front lines for the first time since the invasion. this as president biden is now ruling out weapons to ukraine that could strike russian territory. >> welcome to our viewers in the

united states and around the world. wolf blitzer is off today. i'm jim acosta and this is a "the situation room" special report. >> and we begin our coverage this evening in the town of uvalde, texas. still heartbroken and grasping for answers nearly a week after the robb elementary school massacre. let's get to lucy kafanov in uvalde. new audio and video evidence keeps pouring in from the crime scene. what else can you tell us? >> that's right, jim. official accounts of how police have responded to the shooting have changed wildly over the past few days. some of the new information includes dispatch audio informing officers on the scene of a child calling 911, saying they were in a room full of the victims. the police response now the subject of a justice department

investigation. >> a chaotic scene as police rushed to evacuate children. dispatch audio revealing some police were aware at some point that kids were still trapped inside. >> he is in the room full of victims. >> more devastating details from officials of at least two children calling 911 multiple times. pleading for help as the gunman is still inside the school. for more than an hour before police enter a classroom and kill him. frustrated at the scene by one account, the border patrol decides to go in without orders from the police chief and command. >> what's been made clear to me is that at that point, the cbp team that went in in frustration said we're going in. >> the police response is now under investigation by the department of justice. >> at the end of the day, everybody failed here. we failed these children. >> there were maybe some errors that were made. i am filled with anger, but i feel no hatred towards him. we were thankful to have ally

for the 9 years of her life with us. >> two services are taking place today. visitation and rosary for amerie jo garza and tonight a memorial service for maite rodriguez. president biden visited uvalde on sunday to offer support for the victims, the second time he's visited a community devastated by a mass shooting in the last two weeks. the most critically wounded were brought to san antonio's university health hospital. >> so anesthesia is on their way, blood bank is on their way. >> cnn got exclusive access inside. >> this is one of the teams we formed and the day of the mass casualty event. >> as pediatric trauma medical center director dr. lillian and her team drilled for another mass shooting. >> four of the victims were brought right here to university hospital. three little girls and the shooter's grandmother. some of the doctors and nurses say that responding to these kinds of mass shootings is taking a personal toll.

>> i kind of thought back to -- when i was 10 years old. so when i was 10 years old, my family immigrated to this country. and my biggest challenge was learning to speak english. and you just can't imagine what these children are going through. and it's really unfair. it's really unfair. >> trauma nurse crystal flores recalls the agonizing wait for patients and the realization that it was too late for most. >> i felt like forever for the next victims to come in as well. i just wish they would have been able to get to them quicker, for sure. >> she tears up when thinking about her little ones. >> crying, my husband started crying. he did tell my son, something really bad happened.

>> a lot of crying that day. >> nurse colleen davis says she keeps thinking about the pain suffered by the victims' parents. >> most of have us children so it's very difficult. trying to imagine them calling around, praying their child is there and us having to tell them wi don't have that patient here. >> you heard the emotion from the surgeon and the nurses. these are people literally trained to be with human beings in their worst moments. and i keep thinking about the concentric circles of trauma that are created in the aftermath of a mass shooting, for the first responders, the doctors, obviously the parents and survivors of the shooting. but also the community at large. many of whom have been gathering here all weekend to pay their respects. many of whom, jim, will be carrying invisible scars for the rest of their lives. jim. >> all of our hearts are broken over this. losa kafanov. thank you. >> let's get more on the justice department's investigation into the shooting. our senior justice correspondent evan perez is joining us. the department is reviewing the police response at robb elementary. a big step. what are we learning?

>> it is a big step. one of the things they want to do here, jim, is look at whether the best practices such as they are, whether there's a problem there, whether there needs to be more training for police departments. unfortunately, we have a lot of these incidents in this country, we're unique around the world in having these types of incidents. so the police are having to fine tune their responses. in this case, this was a review that was requested by the mayor of uvalde. and it's going to be done by an independent group of experts that the justice department is going to bring in. these things take sometimes three months or so. we expect they're going to do hundreds of interviews. they're going to talk, they're going to want to talk to survivors if they can, some of the family members who were there outside, urging police officers to go inside the rescue their children. and you know, at the end of this, this is being done with the community oriented police unit, justice department, and we expect what that's going to do is provide some guidance for

police officers going forward. we're also going to hear maybe an independent account of what exactly happened that day. i'll read you just a part of what the justice department says they're trying to do here. it says the goal of the review is to provide an independent account of law enforcement actions and responses that day and to identify lessons learned and best practices to help first responders prepare for and respond to active shooter incidents. and that's the thing that, you know, i think going forward for police, they want to know, is there something we can do better. >> yeah. so it doesn't happen again, but unfortunately, we know it probably will. evan perez, thank you. >> let's continue this discussion with cnn law enforcement analyst jonathan wack row and elliot williams. how disturbing is it to hear that apparent dispatch audio advising a child is in a room full of victims knowing how the police response played out? >> jim, it's beyond disturbing.

let alone the 911 call. the officers that were there, that were outside that door, within about ten minutes. we know that from the accounting of the dps when they put out what they'll call the actual timeline. they had to hear those children in there screaming. no one is keeping 9 and 10-year-olds quiet in a situation like that. they had to hear if they stood outside the door, the children screaming, people yelling, and the wounded. and again, we talked about it previously. it's a lot of indecisiveness. this investigation will dig into training records, weapons qualification records, how do they exercise crisis management, command and control, and the decisions that go along with that. >> and jonathan, it's unclear if there was ever a word to breach the classroom. the texas state senator says border patrol agents ultimately went in out of frustration. you believe this delay cost children their lives, don't you? >> i absolutely do.

the other day i said to you, jim, i think and wholly believe this incident is the worst police failure in modern u.s. history, and the more information that comes out about that day, just reaffirms that statement. as my colleague had just said, they were defenseless children that were in that room screaming. they were on the phone calling 911. they were defenseless. the people that were there to rescue them waited outside. they had the tools. they had the techniques. they had the experience to go and breach that room. why was that call to wait? why were they held back? basically, this comes down to a complete breakdown of the incident command structure in responding to this critical incident. the wrong person was in charge. that person is going to be reviewed. but they made the wrong call about not breaching that room. level of frustration, when you had federal agents show up at the site who were trained, who had all of the equipment that

was necessary to breach and take out that active threat, when they were told to stand down, that is astronomical to hear that actually occurred. killing was active at that time. that was an active shooting situation, and the first priority of all officers is to stop that attack, to go in and draw that gunfire away from defenseless children. it's stunning, the information that we're hearing, jim. >> just doesn't make any sense. it doesn't add up. and elliott, one of the most pressing questions the justice department review will need to answer for the families, do you think? >> there's several. number one, as we have already heard, human error and judgment. there were a series of staggeringly bad decisions made up and down the chain of command. who made them, why, and do they speak to sort of a broader failure of training and experience within the uvalde police department? number one. number two, communication. who is giving the orders to whom? as the point was made that when

the border patrol agent showed up, it wasn't clear who was in charge, and who is telling people to breach the building go in? law enforcement can be notoriously territorial about turf. and when you have multiple agencies together, who is calling the shots there? and that and sort of how that played out is another important question. number three, just equipment and training in some of these technical questions that were clearly failures. like there was a report of someone having to borrow a shield from a deputy u.s. marshal. they got to get into the school, at a certain point, where is the equipment, who has got it, and who's in charge? sort of a bit of a comedy of errors that the justice department really needs to get the bottom of to insure this doesn't happen again. again, the most important point to be made here is this is about looking forward. yes, there's very important opportunity to look backward as to what happened and to grieve and to mourn, but we cannot let this happen again. that's really the justice

department's charge. >> and peter, the justice department did reviews also the pulse nightclub massacre and after the attack in san bernardino. we thought lessons were learned from columbine and sandy hook. is this really the root of the problem or is it the accessibility of these deadly weapons? >> from the law enforcement standpoint, it's really about, it's the prior. it's about their training. the weapon is the weapon, but that situation could have been mitigated a lot more with proper decisions, proper communication. i have been on numerous crisis situations in the fbi. i have been a recipient of the training from the lessons learned from columbine, from san bernardino, from sandy hook, from all of these active shooter, horrible active shooter situations. communication is the first thing to break down, but you have to work through it. that training, being properly

equipped, somebody not having a shield, officers are all supposed to have tactical gear in the trunk of their car. a helmet, a vest, proper weapon. they didn't have that. that's what the lessons learned are going to take, and hopefully we're not going to stop this active shooter situation in america again, unfortunately, but the response, the lessons learned should be taken to prevent this from happening, the delays from happening in further responses. >> jonathan, we can't neglect to mention over the weekend there were more shooters. a 1-year-old killed in pittsburgh. five injured in chicago. eight injured in oklahoma. there you see chattanooga, the list goes on and on. what does this constant gun violence do to a country with so many people on edge, and what's the bottom line for you? >> listen, the constant killing of innocent civilians at the hands of individuals is deteriorating our communities day after day. and it's broken up only by these

really tragic mass shooting events. but every single day, this is a persistent threat that faces the united states. and we have to take a different approach on how to deal with this. a whole of community approach, and that's what i think this review will start to bring to light. >> yeah, everybody is wondering, you know, is my community next? we shouldn't live that way. all right, gentlemen, thank you very much. coming up, after a heartwrenching visit to uvalde, president biden is showing new optimism on gun legislation, hoping some republicans will budge. that's next. this is a "the situation room" special report. terally right be.

president biden said he

hopes everyone is getting, quote, more rational about guns in the wake of the horrific school shooting in texas, this after he and the first lady paid respects to the grief stricken victims in uvalde this weekend. phil, has the administration announced any plans to tackle this issue? >> you know, the president made clear his belief that some of those he believes are now rational coming to a realization that the nation can't go on like this in the wake of the uvalde shooting are republicans. thep rns he would need to move anything forward on capitol hill. when it comes to specifics, the president and the white house have been very cautious. given lawmakers on capitol hill space to try and find some type of a pathway to get something done. something that hasn't gotten done in decades of efforts, efforts the president has often been involved in, either as a legislator or in an administration. one thing, however, jim, the president made very clear, he doesn't believe he can do that much on his own. take a listen.

>> there's the constitution. i can't dictate this stuff. i can do the things i have done, and any executive action i can take, i'll continue to take, but i can't outlaw a weapon. i can't change the background checks. i can't do that. >> jim, those actions obviously are in the purview of the legislative branch. one of the republicans that president biden labeled as a potentially rational republican, senate minority leader mitch mcconnell who has often opposed gun reform efforts. at this point he has given some of his members the green light to negotiate. other democrats on capitol hill very skeptical mcconnell may be there in the end, but the point person on those negotiations, john cornyn, said republican and democratic lawmakers will meet via zoom tomorrow. negotiations are ongoing. >> we also heard from president biden today at earlington national cemetery. how did he mark the day? >> a day laying out in detail the somber moment this day represents. breakfast with gold star families, laying a wreath at the tomb of the unknown soldier,

followed by remarks at the amphitheater there where he acknowledged this is a day that comes with a mix of pain and pride. he also referenced his late son, beau. today happened to be the seventh anniversary of his death. in fact, the president started his day in delaware visiting beau biden's grave and came here to commemorate memorial day, jim. >> all right. phil mattingly, thank you very much. >> sadly, some parents know all too well what 19 families are going through in uvalde, texas. one of those parents is nicole hockley, cofounder and ceo of the sandy hook promise foundation. her son dylan was 6 years old when he was killed at sandy hook elementary school. she joins us now. thank you so much for making time for us. we appreciate it. the families of the victims in uvalde are starting to say their good-byes with funerals getting under way. something no parents should ever have to do. what advice do you have for them and how can they possibly get through this? >> the only way i got through it

was through the support of friends and the community around me. no parent thinks about how do i plan a funeral for my child or a memorial service or pick a casket or an urn, and for me, it's really about leaning on your friends and family. they are there for you. allow them to help you. everyone is hurting. and the more that you can rely on other people to do these horrible tasks for you, then you'll be able to focus on yourself and any surviving family members you have or surviving children because that's what's needed for you and your family right now. >> they're just dealing with so much unspeakable grief right now, it's hard to imagine. president biden promised to act after a crowd in uvalde was chanting at him for him to do something. he was saying back to them, we will. but congress failed after sandy hook, as you know. what do you think it will take to actually enact changes that could prevent another massacre? >> i really hope that this is the moment. you know, we have been -- we

have been building to this for the last ten years since sandy hook. the movement has been demanding, the demand for sensible reform has been building. i think this second huge massive shooting at an elementary school is finally the tipping point. there are conversations taking place with surprising people and people are leaning in. members of congress do want to find a solution. i have a feeling this is the time we're going to see things happen. it's not going to be the perfect solution and there are other steps we might have to take along the way, but i think we'll see genuine, sustainable and meaningful movement happen in the next couple weeks. >> just seeing one thing happen, one proposal get passed and signed into law would be remarkable given what we have seen over the last decade. one texas state senator says they're looking into razing robb elementary school and building a new elementary school. that's what happened after sandy hook. is that something that you think could give survivors some peace

of mind and give the community some, i guess some sense of calm that they can send their children there? >> you know, that's a really tricky one, and each community has to deal with that in their own way. it took some time, we were very fortunate there was a school next door that all of our kids could go to while they figured out what to do and the town did decide to raze the school and had to rebuild it on the same footprint practically, but i don't think that is -- that doesn't give closure. that might make it easier for some people to return because it's a new space, it's fresh. those memories of what they have seen and heard is not there, but there's a lot more required in terms of theirably and support than just changing buildings. this is just the start of a long journey for this community. >> you shared you were afraid of forgetting what your son sounded like, what he smelled like. but you say that you never forget. is that something these families are going to experience?

>> that's certainly a fear i had, and i have heard of other survivors who have the same thing, just forgetting what it's like to hold your child, what they sounded like, and as one parent, i can definitely say that fear is unfounded. you never forget your child. and how special they were. and you just pray for those moments that the memory comes back or a dream comes back and you're holding them in your arms again. >> and we're showing pictures of little dylan there, such a beautiful boy. nicole, thank you so much. and thanks for what you do, speaking out when these terrible tragedies happen. your input is greatly appreciated. thank you so much. >> thank you. and up next, ukraine says regions in the east are suffering from maximum intensity, a maximum intensity russian assault. can ukrainian defenders hold on even as president biden is ruling out sending long-range artillery to the war zone? graded on her green investments with merrill.

ukraine is warning russian forces are striking with maximum intensity in the east as vladimir putin's army makes a furious push to capture key cities in the donbas region. president biden says they won't send rockets that could reach russian territory. >> this is the last road into luhansk. putin's forces have moved with rare focus and may encircle the two cities on the river we're driving into. the ukrainian forces we saw here mobile, tense, at times edgy. and this is why.

across the river here, the besieged city of donetsk increasingly more in russian hands, whoever you ask. we can hear the crackle of gunfire down towards the river below. we were told the russians have tried already to get into town, and it looks like we might be witnessing another attempt over there. that smoke near one of the remaining bridges into the city. our police escorts shout "drone" often used to direct artillery attacks. we are on high ground, exposed and scatter. it is a tale of two desperations here. that which makes people stay and that which makes them finally flee. this is the latter.

some who stay are increasingly angry at what's left of the ukrainian state here. a young woman was killed here a day earlier by a shell. and locals told us not to film, saying cameras attracted shelling. russia's bloody persistence and unbridled fire power is bringing the kind of victory in the ruins they seem to cherish. this cinema was a bomb shelter, local officials said. it's unclear if when the huge air strike hit, the russian military was aware it had been empty days earlier. >> just startling how whole chunks of this cinema have been thrown into the crater there. this is the ferocity of the air strikes we're seeing here,

designed simply to get people out of this town. >> those who stay among the shards of glass feel abandoned already. many, many people, but there is no gas or water or power or anything. we ask the aid workers today when it will all come back. they said there are only prostitutes, junkies, and alcoholics left. that means the aid workers have left here. >> lydia is carefully picking up the pieces of the air strike, which she felt the full force of in her apartment eight floors up. >> there's an old lady on the first floor and me with my disabled son, she says. he doesn't really understand the war is happening. retreat lingers in the empty air. if putin takes here, he may claim he's achieved some of his reduced goals in this invasion. it's now the unenviable choice of ukraine's leaders if this is the hill its men and women will

die on. the possibility of a limited victory there for the kremlin edged closer today when ukrainian officials admitted russian troops have got further towards the city center of donetsk and that pressure will extend into luhansk where today a french 32-year-old journalist was killed as he filmed in an evacuation truck, killed by russian shelling, jim. >> terrible news about that journalist. and nick, while we have you, let me ask you this. the u.s. is considering sending ukraine a rocket system, but president biden today told reporters he will not send anything that can fire into russia. just how badly does ukraine need these weapons? what do you make of that? >> they certainly need something to match the ferocity of the older grant type rocket systems that russia uses on an hourly basis, frankly across the eastern front there. the system which they're

requesting, ukraine, from the united states is a technological leap ahead of that, frankly, and has a range of hundreds of miles. potentially joe biden's comments, well, if you parse them carefully, he's not saying he's not going to give them the rockets. he's just not going to give them in such a way they might be able to fire into russia. does that mean ukraine might get them under strict conditions not to fire them into russia? clearly, the white house worried about the escalatory message that could be if indeed those rockets were used to strike deeper inside russia. but you have to remember, in all of this, jim, the u.s. has not been holding back in arming ukraine. they have sent massive amounts of stuff and will continue do so in an increasing fashion, and that's changing the war in ukraine's favor, but here in all of this, a biden administration very cautious about giving moscow the excuse to change the narrative from one about them invading their lesser equips neighbor to one about the united

states somehow being more involved in this war. >> that is the kremlin line we hear over and over again in state media, that this is russia against the world. in all of this. let me ask you this. today, the russian foreign minister, sergey lavrov, commented on rumors about vladimir putin's health, which is remarkable in and of itself. what can you tell us? >> look, it's important to be absolutely clear. there is at this stage no evidence that vladimir putin has any health problems, apart from that you might normally expect from a man in his 60s who spent most of the pandemic in isolation. according to the foreign minister, they're responding to rampant speculation in the western media, often anonymously sourced, often poorly sourced they he may have cancer, other debilitating diseases. sergey lavrov said none of that is the case. this is a man who daily goes about his work in full public view and he has no ailments or sicknesses, but the fact that we

have a pretty senior russian official having to comment on this kind of speculation is probably a reflection, frankly, of how loud it's got. maybe it's a reflection of concerns inside of moscow, but you know, you and i, jim, reading the kremlin is almost impossible. that's the whole point. there have been kremlinologists who have failed to do that for decades, but this question will continue to reverberate. at the end of the day, it doesn't appear to have loosened putin's grip on power despite whatever you read from these videos about how he may have changed over the past ten years. >> it's difficult to take anything the kremlin says as fact. nick paton walsh, excellent work as always. thank you very much. we appreciate the time. >> just ahead, house speaker nancy pelosi's husband arrested and charged with driving under the influence. what the speaker is saying about it next. lve together, and find the answer that was right t under their nose.

>> also tonight, the january 6th committee is closing in on next week's blockbuster public hearings, the first of the year. congressional correspondent ryan nobles is joining us now. there are still subpoenas out there for five republican lawmakers to appear and answer questions. they're digging in their heels. >> it's played out the way we thought it would but it's left an open question as to how the committee is going to respond to this. the committee issuing five subpoenas to republican lawmakers and all five of them have objected to the committee's request that they appear before a committee investigator and answer questions. so that leaves the committee with a decision here. how do they proceed and how do they attempt to enforce these subpoenas? it's something they have been vague about up until this point, there are a number of aungz opt the committee can take. they can offer up a referral to the department of justice, something they have done with other witnesses who have not been as cooperative. it's a little more complicated with members of congress.

that could be one reason the committee have been reluctant to say what step they'll take. one other option would be to send this matter to the house ethics committee, which would then determine the next step forward, but the sum total of this is that the committee says they need information from these five republican members, including the house minority leader, kevin mccarthy. they're essentially daring them to punish them for not agreeing to comply with these subpoenas, and at this point, the committee doesn't have answers as to how they're going to proceed. >> any sign as to what we're going to see at the hearings? >> we know for sure at least two of these hearings will take place during the primetime hours. and that they're going to cover a number of topics that committee investigators have uncovered over the more than -- again, the ten months or so of their investigation. the big question is, jim, we know they're going to try to establish a narrative of what happened on january 6th. from the period of time after the election right up until the insurrection at the capitol. the big question, though, is

will they provide any new information that we haven't seen yet? they have conducted somewhere in the range of 1,000 depositions. they have interviewed a number of witnesses. tips, hundreds of tips. the question is, is there something that we haven't learned quite yet that is something that the committee's at least hinted will be revealed in the hearings. >> congressman jamie raskin said these hearings are going to blow the roof off the capitol. >> they're setting expectations. the big question is will they be able to meet those expectations. >> thank you very much. >> coming up, covid cases are five times higher in the united states compared to last memorial day weekend. what does it mean for your plans? we'll get expert analysis after the break.

sentiment. as in it's just not practical for us to tell people not to gather, to defer their travel, to not see each other anymore. and so as a result, i think we need to focus on how can we still make gathering safer for those who are particularly vulnerable. if you're getting together with somebody who is vulnerable, take a rapid test right before seeing them. for people who are immunocompromised who have chronic medical illnesses, they should have a treatment plan, they should know where they'll get treatment, what antivirals or other treatments they're eligible for and have that treatment plan so that in case people do get covid, which is very likely when there are high numbers of cases, they will know what to do. >> doctor, there still seems to be some confusion about how long people should isolate after testing positive, particularly if they continue to test positive after their symptoms have passed. what do people do at that point? >> yeah, so the cdc says that people should isolate for five days after they test positive or

start having symptoms. and then they can go out in public but they have to wear a well fitting mask for the next five days. i don't think this is enough. i think having a rapid test, this is important, a pcr test will keep testing positive for some time, but take a rapid home test. if that rapid test is still positive even if you're on day 6 or day 11 or 12, and even if you don't have symptoms, if your rapid test is positive, you could still infect other people. so i would really test out of isolation rather than just assume that once you hit a certain number of days that you're fine to see others. this especially applies to people you live with. it's just not safe to see others indoors in your home until you start testing negative. >> dr. wen, turning to the baby formula shortage which has so many parents concerned across the country, 70% of product nationwide was out of stock for the week ending may 27th. that's way up from the week before. what can parents do until these shipments from abroad start to

ease this crisis? it's very painful for a lot of families to deal with this. >> yes, and i think a lot of parents are so desperate, so what i would say is, first of all, find any fda-approved formula. that is always the first choice. fda-approved baby formula even if it's not the brand you normally use, that's definitely by far the first choice. american academy of pediatrics also says if parents are truly in a pinch, and your baby is 6 months or older, you can also use whole cow's milk for temporary replacement for a couple of days while you wait for formula. but here's what not to do. don't dilute the formula down because having excess water could be extremely dangerous, even causing seizures or leading to death in infants. and don't make your own homemade formula because some of those could have bacterial contamination or may not contain the right level of nutrients and

electrolytes. find an fda-approved formula. >> and what are the long-term solutions here so we don't have to go through this all over again? people are pulling out their hair over this. >> right. i think there needs to be a reckoning over how we got to where we are. why is it that three manufacturers account for 90% of the baby formula supply here? we need to increase competition and also have a stopgap so that this doesn't occur again. and i don't know what the stopgap solutions might be, but it might be allowing for importation faster or having ingredients that other manufacturers are able to make, but i think this really illustrates to me the fragility of our supply chain and should be a wake-up call because this is not just about baby formula. we're now also having a problem with iv contrast, which are needed for ct scans, and there are a lot of other medications and supplies that are really crucial for people's survival, and we have to figure out those supply chain issues too. >> all right, dr. lena wen,
