49-year-old tralona lives lost families shattered. >> our hearts go out to all the victims killed during this senseless act of violence. >> thanks to sunlen. thanks to all of you. anderson starts now. good evening, flags are flying at half staff at the white house tonight again. they were lowered today for victims of the mass shooting in boulder, colorado. they had just been raised briefly yesterday after honoring the victims at the atlanta-area mass shootings. after a long year of covid, just as we finally have a hint of normal back, this is a reminder that part of that normality that returns is gun violence. in colorado, every sensation that follows, there's the numbness and ache that is

compounded by familiarity. this is for accoloradans the thd mass shooting in a generation. >> i don't need to wait another minute let alone an hour to take common sense steps that will save the lives in the future and to urge my colleagues in the house and senate to act. we can ban assault weapons and high-capacity magazines in this country. once again, we can close the loopholes in our background check system, including the charleston loophole. the united states senate, i hope some are listening, should immediately fas two-house bills that closed loopholes in the background check system. these are bills that receive votes with both republicans and democrats in the house. this is not and should not be a partisan issue. that is an american issue.

it will save lives, american lives, and we have to act. >> tonight we'll talk about the chance for meaningful gun legislation with senator chris murphy who worked hard for reform after the killings at sandy hook elementary. we're joined by a survivor of this latest horror in just a moment and we'll bring you up to the minute on the investigation. but before we do. >> no, sir, we want to focus on those whose lives were taken so savagely yesterday. this is rikki olds. she was the front-end manager at kingery soopers and was at work yesterday when the shooting began. friends called her a strong, vie vicious, vicious woman. her uncle called her a shining light in this dark world. ricky olds was 25-year-olds. denny strong also worked at king surpz grocery store. according to "the new york times," people knew him told the "times" he was one of the kindest people

around. denny strong was 20. tra loan in a bartkowiak was called l"lona" by her friends, and she had many of them. according to the denver post, she owned a clothing shop in boulder. her brother told "the new york times" she had simply stopped by the supermarket to pick up her subscription when she was shot. officer eric talley was the first officer return to into the store. he arrived on scene just minutes after the first reports of shots fired. it wasn't surprising to those who knew him. his colleagues say he was an outstanding officer and he died a hero. officer talley joined the police force in 2010. he had a big family, seven children, and he loved that family more than anything in the world. he was recently looking to become a drone operator because he believed it was safer. officer eric talley was 51 years old. lynn murray was a former magazine photo director and a mother of two, according to "the new york times." her husband called her an

amazing woman who now leaves behind two children. she was 62. kevin mahoney was caught in the line of fire yesterday. just last summer he had the joy of walking his daughter down the ale at her wedding. his daughter posted this picture on twitter to honor her dad. i love you forever, dad, you're always with me, she wrote. he was 61. we don't have information or a photo of neven stanisic, but he was just 23 years old. suzanne fountain was 59. jody waters was 65 years old. and teri leiker was 51. as a reminder, we will not be mentioning the shooter by name or showing his picture. we don't want the focus to be on him, but it is important to understand more fully what we did not yet know when we left you last night. there are late developments to report with that. here's lucy from boulder. what do we know about this

alleged shooter and the weapon involved and what happened? >> reporter: well, anderson, we know that police have recovered two weapons from the scene as senior law enforcement source confirm a ruger ar 556 pistol that the suspect purchased on march 16th was indeed the firearm used in the shooting. that source also confirmed that the suspect was carrying a 9 millimeter handgun during the incident. >> down here. >> oh, my god. guys, we got people down inside king soopers. look -- [ gunshot ] >> holy [ bleep ]. >> reporter: shots ring out and panic sets in. the early moments of terror captured on live stream. >> 136, hold the radio. >> reporter: at 2:40 p.m. local time, police are on the scene at the king soopers grocery store after a report of an active shooter. >> multiple shots and he fired

at us. we're taking multiple rounds. >> i looked at my son and i told him in between shots if by the fourth shot i started counting -- and i told him we have three seconds. stay low and don't look and just move fast. and he almost hesitated and i just told him we don't have another option. we don't have any more -- any other chance to get out of here. >> reporter: eight minutes later, this tweet from boulder police urging residents to avoid the area. >> suspect in the building, this is the boulder police department. the entire building is surrounded. i need you to surrender now. >> reporter: officer eric talley is one of the first to respond, one of the ten victims in the shooting. >> i initially heard maybe ten gunshots. i also saw the gunman himself holding a semiautomatic rifle. i heard screaming.

i heard people leaving in their cars and it just devolved into chaos within just a couple of minutes. >> reporter: by 3:14 p.m., more gunfire. s.w.a.t. vehicles and hundreds of officers are on the scene. >> we're taking rifle fire as soon as we control entered the building. we need the rolling shield up here asap. >> reporter: seven minutes later, officers are still trying to determine the location of the gunman. >> be advised, we do not know where he is. he is armed with a rifle. officer shot back and returned fire. we do not know where he is in the store. >> reporter: by 3:28, the wounded suspect is taken into custody and to the hospital. one senior law enforcement source tells cnn the weapon used as you an ar15-style firearm, but still no word on what was behind the violence. >> no, no motive at this time. it's challenging. i live three blocks up the street from that store.

>> reporter: the boulder, colorado, police chief expressing what an entire community is now feeling. >> you're yoworried about your neighbors, your partners, everything when you get that call. and so, yeah, i feel numb. and it's heartbreaking. >> what activity have you been seeing in boulder tonight? >> reporter: well, anderson, police have blocked off the area surrounding the grocery store with a chain-link fence, but throughout the day we've seen a steady stream of visitors coming by to pay their respects to the ten victims who so tragically lost their lives on monday afternoon. we've seen dozens if not hundreds of flower bouquets, notes offering condolences, a very somber and emotional scene. i took a walk past there just moments ago. but i can tell you that whole area, the focus of attention will move in an hour to the pearl street mall for a vigil for those victims. it is a famous shopping and dining area here in boulder.

anderson? >> appreciate your time. thank you. one of the survivors, maggie montoya, is a pharmacy tech at the king soopers and joins us now. maggie, i'm so sorry for what you've been through. i appreciate you talking to us. first of all, how are you doing? >> i'm okay. physically okay, just -- yeah. working to think all this through. >> we mentioned ricky olds at the top of the program. i understand you knew her. she sounded like a really good person. >> yeah. she was fairly close with the pharmacy staff. she was always checking in on us, grabbing our tills at the end of the night. we had all been working a lot of overtime hours and she was always giving us the overrides to leave and asking us about our day and just -- just a phenomenal, phenomenal lady.

and just heartbreaking. we're the same age and just feeling so young and knowing that she's gone too early. >> when did you know something was happening yesterday? >> i was signing people up for the covid shot and the next person in line was my store manager, sherry and her sister, getting ready to get the shot. and i heard the first shot and sherry just yelled active shooter and we just all scattered just at the first sound, the first rounds of it, of the shots. we just -- everybody went their separate directions. i didn't know where everybody went. yeah. >> where did you go? >> i ran into the coming room. it's the entry point for the pharmacy and also where we administer the vaccines. >> where did you hide?

>> there was two desks in there. i hid under the far desk against the wall. and my pharmacist, carrie, who was in there with me, she was right by me. she was standing the whole time behind the wardrobe as much as she could. she just held a chair there the whole time. ready to throw if we needed whatever -- whatever we needed to do. >> what did you hear? >> a lot of gunshots, a little bit of screaming, and then just -- it was quiet. it was quiet for a long time with just the store music. and then random shots of fire throughout the store. and then our pharmacy phones kept running off. we probably received 20 calls in that hour that were just -- just nerve-racking because we had to silence them.

but silencing them -- we were worried that he would hear us. >> when you say you were silencing them, you would pick up the phone and press -- turn it off? >> my pharmacist would put down the chair and lean over and hit the hang up button. we had one phone in the counseling room. all the other ones were out of reach where the people in the pharmacy to access coming out from the back. so we had to silence the phones from our end. >> were you afraid that the phones ringing would attract the shooter? >> we were afraid that the constant ringing would attract the shooter but we were worried if they kept ringing that would bring his attention and then worried that if we silenced them, that would bring his attention that there was someone in there silencing the phones. but we just silenced them. >> i know you were able to call and text family and loved ones as this was happening. >> yeah.

as soon as we got in the room, my pharmacist dialed 911 from the phone in there. i dialed 911 from my phone and after the next couple rounds of shots were fired off, i hang up on 911 and called my family, called my parents instead. >> what did you say to them? >> i just said, hey, i just want to let you guys know there's an active shooter in the store. i love you. i listened to what they said back. they were in shock, obviously, hearing that just out of the blue. and then i told them i need to go but i'll text them when i can. >> i mean, i can't imagine how scary it is to be under a desk not able to see what's going on and to just hear shots and then silence and the store music. how long did you stay under that desk? >> for over an hour, we guessed

around, 2:30 to 3:30. >> did you have any sense -- obviously you couldn't see anything. did you have any sense the distance of the sounds how far or near the shooter was? >> all i know is it was loud. they sounded like they were ringing from different locations, but they were all loud. but we didn't realize where he was until the police announced that the building was surrounded and we heard him right outside the pharmacy saying he surrendered, but we didn't know he was so close to us. they found his weapons right by the pharmacy. >> i want to bring in your boyfriend, jordan, as well and show our viewers the pictures captured of both of you embracing after this. jordan, what was going on throw your mind yesterday?

>> disbelief at first. maggie sent me a text when this was all going on and then immediately her mother called me and just wanted to know if i knew what was going on. at that point i didn't, but maggie lives, like, three blocks from that king suoopers and i ws at her house. first reaction was to go there. and then i beat most of the police presence. as soon as i get there, then it went from disbelief to shock. i couldn't believe what i was seeing and what was happening. >> at this point you got there, were there police already on the scene? >> yeah, not the mass of them that eventually came, there were hundreds, but there was definitely a strong police presence when i got there. but, i mean, i was able to park and walk just across from the pharmacy. that's how few were there at that point. >> and were you able to text with maggie or talk at all while she was under the desk?

>> her text to me said, you know, don't call. and so i didn't even want to text her because i didn't want her phone going off and alerting someone. i was texting with her parents and other people that were concerned. i was just there watching everything unfold. >> gosh. maggie, you said that toward the end that the shooter said something. what did he say? >> he said i surrender, i'm naked, and he said that both times in response to the announcements over the loud speaker that he needed to surrender. >> he was responding to that loudspeaker saying i surrender, i'm naked? >> yeah. >> and he was close to the pharmacy where you were at that point at the end? >> yeah. it sounded like he was right outside our door. we couldn't see him through the crack of the door, but it

sounded like we could hear him just so clear. he wasn't yelling that loud, but he sounded like he was right in front of us. >> and then i assume even after you heard that, obviously, i'm guessing you stayed in that room until s.w.a.t. or police came in. >> yeah, we waited till the very moment the s.w.a.t. team -- we heard them rounding -- they jumped the counters of the pharmacy and rounded up my coworkers in the back. and then knocked on the door for us to knock back if anyone was in there. they walked in and then brought out the rest of our coworkers, the pharmacy staff into the co counseling room with us. >> what was it like walking out of the store? >> it was horrible. we saw we think the killer's bloody footprints leaving from the pharmacy out the door.

and then they told us to not to try to look to the side or to our feet so we wouldn't see what was surrounding us. but i was up front and i happened to glimpse to the side. i saw a body and it was just an instinct to look over and that's when i saw that it was -- it was mickey. and then just all of us and the staff, like, we all knew who it was. >> it was your friend? >> yeah, it was rikki olds. he was laying there. and that's when it just all crashed down. of course i was just nervous the whole time i was back there and really anxious and didn't know if i was going to make it out of there. it all came crashing down seeing someone i knew dead, dead there that we're not going to be able

to walk out to her family or walk out the store. >> maggie and jordan, i'm so sorry what both of you have been through. i'm so glad you have each other and have gotten through this. i know it's going to be difficult days ahead for you and so many people in boulder, but i appreciate you talking to us tonight. >> thank you. >> thank you. >> you take care. take care of yourselves. thank you. coming up next, more on the white house effort to make this time different from every other attempts in the wake of a mass shooting to do something about the weapons involved. we'll be joined by connecticut senator phil murphy. we're driving it. everywhere. we emit optimism, not exhaust. we plug in our vehicles as naturally as we charge our phones. we. we are generation e. we want smart. clean. and safe. to also be fun, easy and powerful! ultium! a battery that charges fast. runs long. it fits everyone.

action. he believes we should make moments like these less common. more from kaitlan collins at the white house. what does the president want to see congress do and how likely does he think that is. >> reporter: the bills would basically expand and strengthen background checks, but even before this latest shooting, they were already facing a pretty steep uphill battle in the senate. they don't have the support anywhere close to ten republicans, which is required for it to pass. what we heard from republicans basically all day long, even in the light of what has happened in colorado and of course in atlanta last week is that they still do not like these house-passed bills. so that's going to be another mountain for them to climb. anderson, the president went even further than that today, calling on them to ban assault weapons. that is something that typically you've seen them stay away from when they're trying to get legislation that could actually get passed, though it's been a while since anything significant

has happened. but that is what president joe biden called for today in his remarks here at the white house. >> is there any sense of how much pressure the president is willing to put on senators privately or publicly? >> well, that's going to be the test for him. today he said he hoped senators were watching his remarks here at the white house, but they have other legislative priorities. that's why getting gun legislation has not been at the top of the list for the last several weeks because they're focused on the pandemic, the economic recovery. they have several more bills they want to use for that. that's why that question to president joe biden that a reporter posed to him today about whether or not he thinks he has the political capital to get gun measures passed on capitol hill, he crossed his fingers and basically said i ask her. i s -- i hope so. certainly he learned from his time as vice president, the further you get from the shooting, the tougher it can be here in washington to keep lawmakers' attention. >> kaitlan, stay with us. i want to bring in maggie

haberman into the conversation. maggie, gun control is a fight then-vice president biden took on after the sandy hook massacre in 2012. congress is even more divided now. does anyone think they would be able to get anything done this time? >> the last thing you're going to here president joe biden say is that he can't get it done. i think that he tends to express optimism about all they legislative priorities but i agree with you that i think it is an uphill climb, especially given all of the other pieces of legislation that they want to push through, given how incredibly polarized the senate is politically now, and given the fact that just for almost a decade there's been no political will towards this. i was struck that he talked about an assault weapons ban, which i think almost no one thinks is likely to happen again, but it does put a goal post very far on one end. if the goal is to negotiate back from that remains to be seen:

it's an uphill lift, and the white house knows and the president knows that the public consciousness about incidents like this fade as time moves on, and, you know, news moves very quickly these days. so if they want this to get done, they're going to have to exert a lot of political pressure and i'm not sure that's what they want to do right now. >> kaitlan, to do anything substantive requires, i assume, more than something that they would do by executive order? >> right and that has been the story. it's almost become this unfortunate ritual in washington when something like this happens, leaders call on congress to pass laws. it doesn't happen, there's no appetite for it and then they sign executive orders that don't actually amount often to much. much more has been done at the state level over the last several years than what happened at a federal level. he has several advisers working on potential executive orders related to tougher gun measures that he could take, so you could likely see that. but the question is going to be

does he introduce new legislation, what is that path going to looking like for president joe biden. >> maggie, senator joe manchin signaled he oppose the gun reform bills that passed in the house last week, is still pushing a bill he wushd pat toomey after sandy hook. is the white house engaging with manchin at all on this? >> as far as i know, there's no engagement and nobody thinks that bill has a chance of going somewhere. obviously emerged as a key figure who the white house is paying attention, to but they're still figuring out exactly how they're going to go about this if they make a huge push to go forward. they will try to do something given everything else they have on their plate. i'm not positive that this is going to be a huge effort right now. >> yeah. maggie haberman, kaitlan collins, appreciate it very much. thank you. coming up, we're going to talk to a lawmaker who's seen the heartache firsthand. the question is, what can be

done? we'll be right back. [♪] looking to repair dry, damaged hair without weighing it down? try pantene daily moisture renewal conditioner. its color-safe formula uses smart conditioners to micro-target damage helping to repair hair without weighing it down. try pantene.

minutes after the world learned ten people died in the colorado shootings, democratic senator chris murphy wrote on twitter that in his words, this is the moment to make our stand now, end quote. murphy is from connecticut where 20 children and six adults were murdered by a gunman at sandy hook elementary school. he's a leading voice in congress

for an assault weapons ban. >> it's not just the families who grieve, it's the trauma that just washes over these communities like waves in the weeks and months afterwards. this is going to be hard. this is going to be difficult. but to honor those 20 lives and six more in newtown, we're going to get it done. >> murphy didn't make that promise today or yesterday or last week. that video you saw came from 2013, only weeks after he took office and barely a month after the newtown killings. back to this day, that return of the assault weapons ban and many other gun violence prevention bills have not become reality. senator murphy joins us now. senator, thank you so much for being with us. you looked a lot younger back then, as i imagine i did as well. you know the obvious and distressing question. if congress didn't do anything to address gun violence after newtown where children were massacred, do you think it will ever take action?

>> thanks a lot for noticing how i've aged in this job, anderson. >> i added myself in as well. >> i know. it was a good save at the last minute there. listen, i think what i learned in 2013 is that, you know, we had won the argument in the american public for universal background checks. we were just badly outmanned politically. the nra spent years building up a political juggernaut and the movement was weak. so we had been building up our own juggernaut. the reason today we have a senate and a house that supports universal background checks and a president who's ready to sign it is because we've been winning more than losing on the issue of guns. the question is can we get it done this year? the reason mitch mcconnell refused to bring a background checks vote before the senate for the last five years is because he was afraid there would be 60 votes to pass it because there's a lot of

republican senators faced with the choice of 90% of their sits on one side and the declining gun lobby on the other. i was talking with republicans all day long. we'll see if we can get something to the floor that can get 60 votes. don't count us out. a lot of things have changed. >> i want to play something republican senator ted cruz said today partly in response to your connecticut colleague, democratic senator blumrichard blumenthal. >> the senator from connecticut said it's time for us to do something. i agree. it is time for us to do something. and every time there's a shooting, we play this ridiculous theater where this committee gets together and proposes a bunch of laws that would do nothing to stop these murders. what happens in this committee after every mass shooting is

democrats propose taking away guns from law-abiding citizens, because that's their political objectivity. >> what do you say to that? >> i mean, ted cruz is really good at yelling. he's not good at telling the truth, and the truth is that states with stronger gun laws have lower rates of gun violence. communities with higher rates of gun ownership have higher rates of gun violence. just take connecticut and florida, for instance. connecticut, one of the toughest sets of gun laws in the nation, florida, one of loosest sets of gun laws. we have 40% less gun rhyme in connecticut than florida does. that's not coincidence or because our citizenry is fundamentally different. that's because we're a lot more careful making sure that people who own weapons are law-abiding and don't have a history of serious mental illness. the data is 100% clear and republicans have sort of resorted to raising their voice

because the american public isn't on their side. 10% of the country agrees with ted cruz. 90% of the country agrees with me. >> i mean, there are two gun safety bills passed earlier this month by the house. you said you're looking for, you know, are there enough for 60 votes. do you think there actually are in the senate to actually survive a filibuster to say nothing of the fact you got your democratic colleague from virginia who doesn't support the house bill. he wouldn't support gutting the filibuster. >> you know, i talked to joe for a while today. you know, it's no secret that he didn't support the house bill, but there's a strong version of expanded background checks that he does support. you know, 2019 seems like a lifetime ago, but it wasn't that long ago. it was right after the el paso and dayton shootings that the trump administration was floating expansion of the bill. senators were saying, murphy, i

voted against background checks back in 2013 but things have changed i would like to find way to get to "yes." there's a lot of conversations that can be had. i think there's a pathway to 60 votes. it's not easy, but i do think it's this. >> it's interesting. as far as a ban on assault-style weapons is concerned, is that even a possibility? that seems certainly an even heavier political lift than universal background checks. >> it absolutely is. but back to data. let's be very clear. when we had a ban on assault weapons from 1994 to 2004, we saw a significant reduction in mass shootings. there were a lot of mass shootings before 1994 and then all of a sudden after assault weapons were legal, there was a dramatic uptick. so there's plenty of data to tell us that an assault weapons ban is a big part of the

solution when trying to cut down on these mass shootings. but you are right, it is a much heavier lift with background checks. let's pass background checks first and let's show republicans that when they support things that are wildly popular, like background checks, the sky won't fall. the gun lobby won't defeat you in your next election. in fact, you'll win more converts. assault weapons bans are only slightly less popular than background checks. the latest polls suggest the majority of republicans now, republican voters support bans on assault weapons. so i would argue, start with a background checks bill and then use that bipartisan coalition to try to move onto other reforms after that. >> senator murphy, i appreciate your time tonight. thank you. >> awesome, thanks. people in colorado are trying to piece together a time line leading up to yesterday's attack. there's also what the suspect's brother is saying about his brother's mental state. all that when we continue.

more on you are a on our breaking news. a senior law enforcement source says the suspect in the colorado mass shooting purchased an ar15-style firearm only days before yesterday's tragedy. that story also confirms it was the weapon used in the shooting. he was also carrying a handgun according to source as his

brother tells us his brother was increasingly paranoid in his words. he pleaded guilty to a charge of third degree assault after attacking a high school classmate in 2013, all part of the landscape authorities are beginning to examine. legal analyst and former federal prosecutor, andrew mccabe, contributor. aur what does it say to you as an investigator that the suspect purchased the weapon to kill people ten days before the shooting? >> it's not that uncommon, anderson. we've seen this in other mass shootings before that perpetrators typically try to arm themselves or you'll see large purchases of ammunition. i remember the aurora, colorado, shooter purchased, i think, 1,000 rounds of ammunition in the weeks leading up to his assault. it's indicative of a clear level of planning.

despite claims of mental illness, that this person was aware of what they were going to do and the tools that they would need to wreak that kind of violence on the supermarket that we saw yesterday. >> ann, for prosecutors, that's one of the things you're doing now is building that case of planning and plotting. >> yeah. that's exactly right, anderson. i mean, this is going to be what you would do as a prosecutor here is you would anticipate that it's going to go to trial and that the defendant here might make an insanity defense. that's already being set up with questions of mental illness. and so they're going to be methodical and get every single piece of information that they can get what the defendant did, where he was, any electronic records that they would have, people he was talking with, anyone he had spoken to recently and doing that the full 360 and they're going to do their best to lock down every piece of information they can about this defendant so that if they go to

trial, they'll be completely prepared. >> ann, also the city of boulder had an ordinance that banned assault weapons, but on march 12th, a judge blocked it from being enforced. the suspect bought the weapon he used to commit the crime four days after that ruling. i know you looked at the ordinance. we don't know if the gunman did purchase the firearm in boulder. if he did, would that ordinance have blocked him from doing so? >> this is one of the more interesting questions. a judge just invalidated this ordinance. there's a lot we still don't know, this ar 556. what is clear, though, is that the ordinance by its specific language, it said that it talked about assault weapons and/or large-capacity ammunition magazines. it specifically referenced the tragic mass shooting in texas in 2017 where the suspect, the defendant there used an ar 556 and murdered 26 people. so it's clear to me that this

ordinance was intended to try to capture this weapon. again, you know, the folks in colorado haven't said that specifically, but it certainly looks to me like it was their intention to capture this type of a weapon and to prohibit it under the ordinance they passed. >> andrew, yesterday there was concern that police haven't released a lot of information or holding back information for a long period of time. is it perhaps them wanting time to not only contact family members, obviously, but also, you know, look at the alleged assailant, go to his home, get all that process without reporters finding out the trail? >> there's no question that by holding back the suspect's identity, they cut themselves a little bit of extra room to do that sort of investigative work. one of the fifrgz rst things yot to do is execute a search

warrant at the suspect's residence. that can be dangerous, for example, with the aurora, colorado, shooter who laid numerous booby traps for the investigators investigators. eventually the name of that suspect has got to come out, especially when you got an affidavit and a warrant to have that person arrested and presented before the judge. it's an inevitable reality. >> the boulder district attorney said investigators haven't identified a motive in the case yet. how are they going to go about that at this point in the investigation just talking to relatives? those who knew him? >> that's a great question. i should say that i know the boulder district attorney, he and i were classmates in the manhattan d.a.'s office together. we started together. he's an outstanding prosecutor, as thoughtful, as thorough as anyone i've ever worked with.

he's going to literally try to go through every single piece of evidence to understand what the motive was. now, we know that when you go to trial in a homicide, you don't have to prove the motive for the crime, but here they will prove that. i have no question they will be able to answer the question for the families of those whose lives were lost as well as for the jury. they'll go about it by interviewing every single person that they can, anyone who knew the defendant, anyone who spoke with him recently, and also, of course, he may have social media posts. there's a lot we still have to learn. but they will track down every single piece of evidence that they can to understand what happened here. >> andrew, as we know, a police officer lost his life in this attack. he was first into the supermarket on the scene. for law enforcement, how does that impact an investigation, or does it impact how they go about doing their job? >> obviously it's an incredible blow for that police department, to the men and women who served alongside that officer. but honestly, anderson, i don't

think it's the sort of thing that negatively impacts the investigation. if anything, those police officers are going to be even more determined and even more energized to do everything they have to do to ensure this suspect faces justice for the violence that he's brought into the lives and the fact he's taken i don't think it's going to slow them down in any way, and it might really force some folks to really focus on what they're doing. >> andrew mccabe, ann millgram, i appreciate it. a new coronavirus update. there's a new controversy over the astrazeneca vaccine and what dr. anthony fauci calls an unforced error by the company. sanjay gupta joins us when we return. an ev for me? what about me? can i get one too? an ev for this princess? what's an ev? and there better be one for me. and what about michelle from michigan? me? what about me? us? will there be an ev for me? me? me? me?

more on the mass shooting in boulder, colorado, that claimed ten lives, including that of a police officer in a moment, but

we want to turn now to the a covid controversy. the makers of a fourth potential covid vaccine are defending themselves after a statement from the health officials which essentially said astrazeneca cherry picked data about its vaccine. this is how dr. fauci explained the controversy. >> this is what you call an unforced error, because the fact is this is likely a good vaccine and this does nothing but really cast some doubt about the vaccines and maybe contribute to the hesitancy. it was not necessary. if you look it at, the data really are quite good, but when they put it into the press release it wasn't completely accurate. >> in a statement this morning, the company said it's stand big its results and would issue a update in 48 hours. perspective now from sanjay gupta. we talked about astrazeneca last night and some of the bad headlines it's received, particularly in europe.

what is this unforced error that dr. fauci's talking about? >> well, basically the unforced error is that they released this data we talked about last night based on a cutoff time period of february 17th. so they had 32,000 people in this trial, studied them up until february 17th, and that's the data they presented. they didn't give us the most recent phi we will be right backs of data. that's it. what astrazeneca is saying is, we have the data, it matches the data we presented. we're going to a shot you that in 48 hours taxpayer data monitoring safety board saw the data astrazeneca put out and look at theirage ses of the data and said, look, it doesn't match system astrazeneca cherry picking here? as you pointed out. that's the real concern. we'll know more in the next 48 hours and hopefully when the fda

analyzes the data we'll get to see their precise analysis. because right now we're taking the company's word for it. this is the first time something like this has happened. >> how concerned are you regardless of 48 hours it contributes to people's fear of the vaccines? >> i think it will, sadly. astrazeneca has had a little bit of a pattern now. you'll remember there was a vaccine trial that was caused for a period of time. that's why we're hearing about the data from astrazeneca so much later. there was this concern about clots in europe, although that didn't really amount to be anything. but this sort of stuff does contribute at least to some skepticism about this particular vaccine. i don't know if it translates, anderson, into skepticism for the other vaccines, and it's a shame if dr. fauci is right that this is a good vaccine, because the world needs it. this is 20%, roughly of the world's supply. >> more than 20 states plan to

open eligibility to -- by the end of april. there's concern johnson & johnson won't meet its goal by the end of month. how will that impact the nation's supply? >> i don't think it will make that big of an impact, but this is a little bit of surprising news. we're talking about brand-name pharmaceutical companies here. they were supposed to have 20 million doses by the end of the month. johnson & johnson has 4 million doses ready to go when it's authorized and there's been 1.2 million doses since then. they would need 15 million doses or so by the end of the month in the next several days. what we're hearing is that's not likely to happen. the number's likely to be closer to 4 million. but you'll remember that moderna and pfizer ultimately we're going to have 300 million doses of each of those vaccines because they're two-dose vaccines. that would be enough for 300 million people.

johnson & johnson and astrazeneca are probably not going to make up any of the extra doses. >> also just in term of treatment, there was new data from regenoron about their treatment. >> we don't talk enough about the antibody treatments. it's essentially giving the antibodies to somebody that the vaccines would generate. and they can be quite effective. there's good data about this. what the new news is is the dose that you could use the regeneron antibodies, you can give half the dose and get the same effect. this is for people who have mild symptoms but are considered high risk. the goal of the antibody treatment is to keep them from being hospitalized. so you've got give it early. and it's expensive. but we're not really using them

that much. maybe this will be an enseincen for people to use them more. >> sanjay, appreciate it. just in terms of where we are in the pandemic, what are your thoughts right now, just kind of big picture? >> this is the big debate right now. i mean, i think you've heard from the cdc, you know, they're worried about a potential fourth surge. you're hearing from other people like scott gottlieb who don't think that's going to happen. we have vaccinated a significant percentage of the country that was most vulnerable, right, people over the age of 65, people in long-term care facilities. that's good news. despite the fact that the country's overall 15%, we have in a good way muimmunized the people that needed it most. i guess what i'm say is i'm worried about the variants and what we saw in florida with spring break, because you could
