floyd. a use of force expert testified chauvin's actions, including kneeling on floyd's neck for more than nine minutes were justified. we're also following a potentially significant setback to the sweeping u.s. covid vaccination effort. the cdc and the fda, they are putting use of the single dose johnson & johnson vaccine on pause after six people who received the shot developed a rare but severe blood clotting complication. one of those people died. cdc vaccine advisers have scheduled an emergency meeting tomorrow. much more coming up on that here in "the situation room." let's begin this hour with more on the outrage over the fatal police shooting of 20-year-old daunte wright. cnn's adrienne broaddus is working this story for us. adrienne, there are very significant new developments unfolding right now. >> reporter: wolf, less than 24 hours after the chief of police here in brooklyn center released that disturbing body cam video showing the officer who was a 26-year veteran here at the police department shoot and kill daunte wright, the officer resigned, and i want to warn you what you're about to see is graphic. >> i'll tase you! >> reporter: tonight the officer who shot and killed 20-year-old daunte wright has resigned. kim porter, a 26-year veteran of the brooklyn police force is seen on body cam video dischanneling her gun instead of a taser during a traffic stop on sunday. >> taser, taser, taser. >> i just shot him. >> reporter: in her resignation letter, potter writes, quote, i believe that it is in the best interest of the community, the department and my fellow officers if i resign immediately. the brooklyn center police chief tim gannon has also resigned. how did these resignations come about? did they catch you by surprise? >> yes. well, i -- i cannot speak to that either. >> reporter: brooklyn center's mayor says the resignations are just the beginning and has asked the governor for the state's attorney general to prosecute the case. >> i'm hoping that this will help bring some calm to the community although, you know, i think ultimately people want justice. they want, you know, full accountability under the law and so that's what we're going to continue to work for. >> reporter: speaking emotionally today, daunte wright's mother explains what she heard when she was talking to her son in the last moments of his life. >> the day that i got the phone call from my son two days ago at 1:47 was the worst day of my life. >> reporter: pointed the phone towards the driver's seat and my son was laying there unresponsive. that was the last time that i seen my son. that's the last time i heard from my son and i have had no explanation since then. >> reporter: joined in a bond of pain and sorrow, the families of wright and george floyd met for the first time outside of the hennepin county district court shaking hands and expressing condolences. the wright's family attorney jeff storm said they are not prepared to say this was an accident. >> it's not an accident to take your gun out of the holster. it's not an consistent to point your gun. it's not an accident to ignore the fact that what you're holding doesn't weigh the same amount as the toys their you've used in training hundreds of times. >> reporter: protests continued for a second straight night in front of brooklyn center police department. police fired tear gas and stun guns to disperse the demonstrators who were defying a curfew and police say were throwing bottles, fireworks, bricks and other projectiles at police. >> in totality, there are about 40 arrests that were made, some cited, some booked in jail for things all the way from curfew violations to riot. >> reporter: meanwhile, wolf, when i smoke one-on-one with mayor elliott he told me he did not accept her resignation and members of the community are calling for the mayor to reject the resignation. community members made it clear they want the officer fired. meanwhile today we're learning a lot more about the makeup of the brooklyn center police department. aamong the 47 officers, only four are black. wolf? >> yeah. we're going to be speaking with jeff storm, the family attorney for the wright and floyd family. we'll speaking to him very soon. adrienne broaddus, thank you very much for that report. meanwhile the trial of former minneapolis police officer derek chauvin entered an important new phase as the prosecution rested its case and chauvin's defense team took the least. our senior national correspondent sara sidner is joining us from minneapolis and has details. sara, update our viewers. >> the defense doing what a lot of folks expected it to, putting on some experts, including a use of force expert who testified to the opposite of what all of the prosecution's use of force experts have said about the way chauvin acted against george floyd in this case. >> your on ork the state of minnesota rests. >> reporter: the prosecution rested its case after 11 days of testimony and 38 witnesses. the jury has now heard and seen all their evidence as the prosecution tries to prove former officer derek chauvin murdered george floyd. tuesday was the first look at the defense of chauvin. chauvin's attorney called a use of force expert to testify. the former officer said chauvin's actions against floyd were by the book. >> i felt that derek chauvin was justified, was acting with objective reasonableness following minneapolis police department policy and current standards of law enforcement in his interactses with mr. floyd. >> reporter: in cross-the prosecution pointed that floyd had stopped resisting and asked if continuing the force was acceptable. >> if someone is not resisting and they are complaint, the use of something, control as you put it that could produce pain, is just not justified, is it? >> no. >> your honor, the defense called scott creighton. >> the question began with the quick questioning of an officer who arrested floyd in 2018. >> i'm not going to arrest you. put your hands on the dash. >> the prosecution's case was clear. >> mr. floyd didn't drop dead while you were interacting with him, correct? >> no. >> reporter: and former ems worker michelle moseng took the stand to testify about floyd's drug use. >> approximately seven percocet, correct? >> documented, yes, seven to nine. >> the defense also called on the woman in the car with floyd when he was arrested in 2020, all of it to bring in evidence of floyd's prior drug use. >> when i tried to wake him up, he woke up the second time. i said floyd, the police is here. it's about the $20 bill wasn't real. i kept saying get up. the police is here so he looked and we looked to the right and he had the police -- he tapped on the window with the flashlight. >> 3 to code four. >> reporter: the jury saw new body camera video from a new officer who arrived at the scene after floyd was detained. officer peter chang was told to watch the vehicle and then began pacing when he became worried about the crowd. ch. >> can you define what an officer should do if they encounter a suspect they suspect is suffering from excited theirium? >> get more resources started because you might need more resources than you would think. >> reporter: and obviously attempt to control the subject? >> correct. >> reporter: through physical restraint? >> yes. >> reporter: so this is the second time that we've heard the use of the term excited delirium which is a real controversial diagnosis, one that the american medical association, for example, does not recognize as a syndrome, but essentially it's the person gets so excited that they have sudden death basically, so agitated. so far we've heard no medical testimony in the prosecution's case that that is what george floyd suffered from. there was a lot of testimony actually to the contrary of that. we also heard again the prosecution pushing that use of force witness for the defense on the stand today talking a lot about that three minutes that the officer was on george floyd's neck after he completely stopped moving. wolf? >> sara, thank you very much. let's bring in jeff storms, the attorneys for george floyd and daunte wright. thanks so much for joining us. i'll discuss the killing of daunte wright in just a moment but first the defense has launched its trial in the derek chauvin trial calling a use of force witness saying that chauvin was justified. what's your reaction to this day one of snm. >> i hope that use of force expert got paid a lot of money because i don't see how a credible lawyer could hire that expert again. we've watched real overs after real overs get up on the stand and say what happened was wrong and had no place in politician, so i just do not see how someone can actually get up there and say what that defense expert said. >> that witness painted a picture of how suspects on drugs may not necessarily feel pain, might have what he described as super human strength. how hard is it for the floyd family to hear testimony like that? >> well, i think that it's -- you know, it's just unbelievable. they don't believe it like anyone else, right? we obviously saw that george did not have super human strength. he had normal human being strength which is why he was able to be detained and asphyxiated by these officers. >> let's discuss the shooting of daunte wright. you're representing his family as well. the officer was killed -- the officer who killed him has now resigned along with the police chief there in brooklyn center. do you have any indication of whether that officer will face charges, and if so when could those perhaps be coming? >> you know, i'm not in a position to comment on that at this time, wolf, but i would expect that all options for justice are being considered right now. >> it was really an emotional moment, as you know, when both the floyd and wright families shared had a moment together today. they met, they comforted each other. you were there on the scene. what do these two deaths reveal about policing in this community? >> you know, this is so unbelievable that this is happening now, but it's also entirely believable, you know. we've had maybe the largest outcry that we possibly could have had in minnesota and one of the largest outcries in the country, in the world, over unfair policing, you know, of minorities here in the united states, and so now this is just the most recent terrible painful reminder that there's still a lot of work to be done and anyone who is patting themselves on the back because we've been vocal over the last year can put their hand away and we need to get back to work because clearly our work is far from done. >> certainly is far from done indeed. thank you very much for joining us. >> thanks for having me, wolf. >> coming up, we'll have the latest on concerns about the johnson & johnson single-dose covid vaccine and a rare but potentially deadly complication. what should you do if you've already received the shot?

it really allows both the fda and the cdc to further investigate these cases. >> reporter: out of the 6.8 million people in the u.s. who have gotten j&j the six with blood clots of women between the ages of 18 and 48 who developed symptoms been 13 days of being vaccinated. one was hospitalized and is in critical condition and another one died. other experts say the clots appear to be extremely rare. >> when you think about a 1 in a million event, you cross the street every day. you have a much higher chance of getting run over by a car. >> reporter: officials said they were concerned that providers would treat the rare clots with conventional drugs that could make them worse. >> when you have tloem bowsies the most common way to treat that is with heparin. that would be a mistake in that situation. >> reporter: for those who have already gotten j&j, dr. anthony fauci says not to panic but be on the lookout for headaches, shortness of breath and abdominal or chest pain. >> first of all, don't get an anxiety reaction because, remember, it's less than 1 in a million. however, having said that, pay attention. >> president biden says he's not concerned the pause will affect his vaccine goals. >> there's enough vaccine, basically 100% unquestionable, for every single solitary american. >> reporter: but his staff is expressing concern about whether the pause will exacerbate vaccine hesitancy. >> hesitancy amongst the group of people is a challenge. the fda acting the way they did today shows that they are indeed the gold stan dad, and i think that should reassure the american public. >> reporter: after some state officials privately complained they were caught off guard by the pause, the white house said they got the message out as fast as possible. >> they didn't know about anything in terms. announcement until last night and we didn't even know the content of announcement until this morning when everyone else read it. >> now, wolf, once they learned the contents of this announcement we're told the federal government started working with states to try to switch those who were scheduled to get the johnson & johnson vaccine in the coming days to get had a moderna or pfizer vaccine and trying to remedy those who are scheduled to get one and now eyes are going to turn to the meeting happening at 1:30 tomorrow afternoon and that's where the cdc's advisory board coming on the vaccine and that's going to be critical and what the next steps are going to be and what the future of this jandsian vaccine is going to look like. >> all right. kaitlan, thank you very much. a very important story. let's get more on this with our chief medical correspondent dr. sanjay gupta. sanjay, can you explain what led to this pause and just how serious it is. >> yeah. i mean, what they did is they found this association with these -- these women that kaitlan was just describing, women between the ages of 18 and 48 who had a somewhat unusual blood clot, a blood clot that's in the drank veins of the brain. blood goes to the brain. that same blood needs to leave the brain. this -- this sort of clot would impede that from happening so it's a significant clot hand you can see the numbers here overall, wolf. as was just mentioned close to 7 million people have received this vaccine. we're talking about six people who have developed this sort of problem, so it's really, really quite rare, less than 1 in a million. a little bit more information. again, women between the ages of 18 and 48 and the symptoms appeared within two weeks, between six and 13 tase, so two reasons i think for the pause is there something that sort of ties these women together? is there some underlying condition, that you know, may give these investigators a little bit more information about what happened here? but also, again, as you just heard in kaitlan's piece, this is an unusual sort of clot. typically someone has a blood clot. they are making too much clompt you give them blood thinners. because of the nature of this clot you would actually not give blood thinners because it could actually worsen bleeding, so that was another reason for the pause. give the clinicians out there some guidance on what to do if they encounter this. >> one of those six women actually died and another we're told is in critical condition. if you've already received the johnson & johnson vaccine here in the united states, especially if you're a woman under the age of 50 who let's say got the shot within the past couple of weeks or so, what should you be looking for right now, sanjay, and when should you actually go and seek medical care? >> well, you know, we can put up the list of various symptoms but as we look at this, when we talk about 1 in a million or less than 1 in a million, this is very uncommon. i can understand the anxiety of people who have seen that within the last two weeks. the statistics and odds are very much on your side. with respect to the blood clot in the brain, headaches that are out of -- very unusual headaches. sometimes blurred vision and in very rare cases seizures could occur. if the clot is not necessarily in the brain but other parts of the body you could have abdominal pain or leg pain. there's something known as a pulmonary embolism that might give you shortness of breath. we've said it over and over again and i'll say it again. it is really rare. i mean, the monitoring system that's in place right now in the middle of this vaccination rollout, it's got the antennas raised really high so they are pick up a all these different things and this is another one of these things. we'll see what it leads to in terms of what happens with johnson & johnson, but i don't think most people really need to worry about this at all. >> i think you're absolutely right. dr. gupta, thanks very much as usual. coming up next, we'll have expert analysis including the emerging strategy from his defense team. we'll also discuss the growing fallout from the police killing of daunte wright. stay with us. you're in "the situation room."

she's a veteran police officer there in brooklyn center. what kind of charges potentially could be coming for her for shooting and killing daunte wright? >> well, obviously, you know, in light of the fact that a life was taken, we could be looking at some -- the second-degree murder, i'm sorry, had the third-degree murder charge in play with chauvin. that's very unlikely i would say because of the fact that everyone is framing it as an accident. we could be more likely looking for anything from a misdemeanor to a manslaughter charge. >> yeah. they called it an accident. she thought she was going to taser daunte wright but used a real gun and ended up killing him. today in the chauvin trial was the defense to present its case. watch what this use of force expert said today to jurors. >> can you briefly overview your opinions in this particular case. >> i felt that derek chauvin was justified, was acting with objective reasonableness following minneapolis police department policy and current standards of law enforcement in his interactions with mr. floyd. >> what's your reaction to that testimony, elliott? >> yes, so, look, we knew that this trial was going to turn, wolf, into a dispute between the experts. we saw several experts testify saying they ended on a use of force expert, so this should surprise no one, and certainly the defense scored points today. the problem with the defense's case is that a number of major points -- at a number of major points he was -- got quite tripped up on cross-examination. there was what constitutes a use of force or pain and he sort of garbled that. on this question of whether officers have a duty to care for people who are in their custody and so, for instance, if someone is saying i can't breathe, i can't breathe, what obligation do officers have, and he conceded that officers in those circumstances have some obligation to care for an individual. would crowd noise -- would an officer who was apprehending someone who had heard a crowd around him necessarily put more force on an individual who is in their custody and, again, he conceded, that well, no, the voice of a crowd would not be the kinds of thing that would lead someone to increase the amount of force and most importantly the simple fact is that would need to be consistent throughout and re-evaluated throughout an encounter with law enforcement so if someone stopped existing or was lifeless ultimately the officer would need to recalibrate the force so yes, he was an affirmative witness for the defense but on a number of instances when challenged he conceded points so i don't think that this was an overwhelming win for the defense and the prosecution prepared the world for this all through last week by putting their own witnesses on first. >> that's a good point. you know, major franklin, does that testimony line up with what you know for more than three decades of experience in law enforcement? >> absolutely not, wolf, and as a certified expert, i'll tell you he was far from, how can i say this, being what i think of an expert and many of the experts that are within my circle regarding experts in the use of force. i'll tell you. it's already been said that he was tripped up on cross time and time again, even talking about risk versus threat, and as was previously mentioned talking about the prone control pox, you know, but -- but most important i think in cross was dealing with the department policy, as we just heard, talking about if they are in your custody, they are in your care, and we all know that, not just in minneapolis but from coast to coast in this country, and he failed dramatically at that. chauvin failed dramatically at that to assess and to reassess as to people on the sidewalk were trying to get him to do, as his own fellow officer tried to get him to do, to place floyd in the recovery position. great cross-examination. the jury is not going to be fooled by this so-called expert >> we'll see how the defense continues its evidence tomorrow. all right. guys, thank you very, very much. just ahead, a new u.s. intelligence report outlines a growing list of global threats to american security. we'll have an update. plus, president biden announces a firm deadline for u.s. withdrawal of all troops from afghanistan nearly 20 years after the war there began. when we started carvana, they told us that selling cars 100% online wouldn't work. but we went to work. building an experience that lets you shop over 17,000 cars from home. creating a coast to coast network to deliver your car as soon as tomorrow. recruiting an army of customer advocates to make your experience incredible. and putting you in control of the whole thing with powerful technology. that's why we've become the nation's fastest growing retailer. because our customers love it. see for yourself, at carvana.com. anxiety and depression. but when i was ready for help, finding the right care was nearly impossible. luckily, he had us. as mental health professionals, we could help him navigate the system. not everyone has that. that's why i started cerebral. online mental healthcare, without the high cost and wait times. with our affordable care model, you can get meds prescribed and delivered. and talk with a licensed therapist on your own time. with cerebral, everyone gets a care team. get your first month for just $30 at getcerebral.com. your mission: stand up to moderate to severe rheumatoid arthritis. and take. it. on... with rinvoq. rinvoq a once-daily pill can dramatically improve symptoms... rinvoq helps tame pain, stiffness, swelling. and for some, rinvoq can even significantly reduce ra fatigue. that's rinvoq relief. with ra, your overactive immune system attacks your joints. rinvoq regulates it to help stop the attack. rinvoq can lower your ability to fight infections, including tuberculosis. serious infections and blood clots, sometimes fatal, have occurred as have certain cancers, including lymphoma, and tears in the stomach or intestines, and changes in lab results. your doctor should monitor your bloodwork. tell your doctor about any infections... and if you are or may become pregnant while taking rinvoq. take on ra. talk to your rheumatologist about rinvoq relief. rinvoq. make it your mission. if you can't afford your medicine, abbvie may be able to help. we're following two major national security developments unfolding tonight. i want to bring in our pentagon correspondent orrin lieberman and our senior national accept correspondent alex marquardt. alex to you, two decades after the september 11 attacks the united states will now withdraw completely from afghanistan marking a very symbolic end to the longest war in u.s. history. what are you learning specifically about the timeline? >> wolf, a senior administration official says the u.s. will begin that withdrawal even before may 1st so that means in the immediate future the u.s. could begin withdrawing the last 2,500 troops in afghanistan. that withdrawal will be complete before september 11th, before the 20th anniversary of 9/11. president joe biden is expected to make that announcement sometime tomorrow and it comes while the secretary of state and secretary of defense are overseas meeting with nato allies. they, too, are part of this withdrawal. a senior administration official said in together, out together. it's clear biden wanted out of afghanistan, but that doesn't mean this was an easy decision. a decision he wrestled with for months taking in account many meetings and what the final position on afghanistan should be. in the end that position is clear. biden wants out that will happen on a very symbolic day on the 20th anniversary of 9/11. 2,500 u.s. troops there now. there will be a military presence there to protect the diplomatic presence, to protect the u.s. embassy in kabul. it's also up clear, wolf, what will happen to special operations forces but the withdrawal is moving forward. >> certainly is. alex, let's talk a little bit about what the u.s. intelligence community did today. they put out a very detailed report detailing the global threats facing the united states right now. there are many obviously. what are the most dire warnings we learned today? >> this is the annual threats assess president, an annual report except it didn't come out last year under the trump administration. it says, among other things, that china is one of the major threats, a near peer rival as they call them. they say that russia is looking to undermine the united states. they talk about iran and north korea, but they saved some of the most dramatic and distressing language for the pandemic. all of these major threats in the world against a backdrop of covid-19. they write in part the economic and political implications of the pandemic will ripple through the world for years. the pandemic is raising geopolitical tensions and great powers are jockeying for advantage and influence. now, wolf, normally this report comes out before what are known as worldwide threat hearings in which the heads of the intelligence agencies go before congress and testify about these major threats. that's going to happen tomorrow in front of the senate and on thursday in front of house. it did not happen last year because back in 2019 under president donald trump when this happened, the heads of the intelligence agencies essentially got up there and contradicted the president on issues like iran and north korea, and he was infuriated. he tweet that had they should go back to school, so when it came time for these hearings and this report last year essentially the intelligence agencies didn't want to do it. they didn't want to put themselves out there to become targets for the president again. the direct orf national intelligence at the time offered to do the hearing in private, but that did not happen. now, thankfully it is happening this year, and say thankfully because these are threats that the american public and the world need to hear about from the intelligence community. for example in, 2019 this report warned about a flu pandemic that the u.s. would be vulnerable to that would cause widespread deaths. of course, wolf, that came to death. >> yeah. sadly it did. you mentioned, alex, the threat the intelligence community sees from russia but president biden spoke with russian president vladimir putin today and actually proposed that they have a summit meeting in a third country. what are you learning? >> reporter: that's right, wolf this is a very contentious relationship. russia mounted a huge influence campaign during the election to den great joe biden in favor of donald trump. when biden came into office he called putin a killer, so this relationship did not get off to a good start but here we have a phone call that happened today. president biden we understand proposed a summit between him and the russian in the a third country, not in russia or the united states. it's unclear when or where that would happen. the white house said that it was looking to make the relationship stable and predictable, to focus less on the adversarial side of things and more on the issues. they are looking to make that summit happen. it's not quite the reset we saw president president barack obama and president medvedev back in 2009 but it does look like the president is trying to lower the temperature a little bit. >> let's see what happens and where they meet. thanks, guys, very, very much. coming up, why the u.s. and china are both flexing military muscle right now in the taiwan strait. cal: our confident forever plan is possible with a cfp® professional. a cfp® professional can help you build a complete financial plan. visit letsmakeaplan.org to find your cfp® professional. ♪ it's okay that you don't want to be first: you aren't. second covid vaccine. it's okay to have questions: everyone deserves answers. i'm wary that there isn't enough information. it's okay to be excited, or worried, or both. it's alright for it to take whatever it takes for you to be ready. hi mom, ready for your shot?

>> hi there, wolf. taiwan, no question, is the most sensitive issue involving china. they consider it to be the red line that the u.s. and others should not cross. now with regards to this unofficial visit you mentioned, it's playing out right now as you and i are talking. in taiwan there's an unofficial delegation from the biden administration. they're there to reaffirm their commitment to the self governed democracy. this unofficial visit comes just 24 hours after a record number 25 aircraft of chinese fighters and bombers breached taiwan's air defense identification zone. now it's left the u.s. in a position to try to figure out exactly how to respond. releasing through state media a flood of dramatic video clips like these, showing chinese naval exercises that u.s. officials say are aimed to intimidate the people of taiwan. >> what is a real concern to us is increasingly aggressive actions by the government in beijing directed at taiwan. >> reporter: considering taiwan to be part of its sovereign territory. president xi jinping has vowed to never allow the self-governed democracy to become formally dependent and will not rule out the use of force, if necessary, to take the island back. >> he's also signaling to the united states, we can prevent you from helping taiwan. >> reporter: the liberation army/navy showcasing its capabilities off the east taiwan coast. military experts say that's a poignant effort to show that china can cut the island off from u.s. military support. from above, near daily occurrences of multiple pla aircraft entering taiwan's defense zone from the west. a coordinated move that is alarming to some experts. it has sparked strong words from taiwan's foreign minister. >> we are waiting to defend ourselves without any question. we will fight the war if we need to fight a war. >> reporter: taiwan has 140,000 troops. chien camera has roughly 100 intercontinental ballistic missiles and 200 nuclear warheads. taiwan has neither. that's why the island is so heavily reliant on allies, most especially the u.s. >> and we have a commitment to taiwan. under the taiwan relations act to make sure that taiwan has the ability to defend itself. >> biden administration officials stop short of guaranteeing u.s. military intervention should beijing make a move on taiwan. instead, the u.s. has been using its pacific fleet to showcase its own strengths. this photo from last week showing a navy guided missile destroyers commanding officer sitting feet propped up as one of china's two aircraft carriers sailed by. while the pla has focused its exercises to taiwan's east, the uncht s.s. john mccain cruised to the west of the island last week. the guided missile destroyer passing through the taiwan strait, right between the mainland and taiwan. in response, chinese officials said the u.s. was stirring up trouble. >> u.s. military leaders believe a chinese attack on taiwan could be just years away. >> i think the threat is manifest during this decade. in fact, in the next six years sxl my opinion is that this problem is much closer to us than most think. >> the biden administration facing mounting pressure on the matter, as tensions at sea rise. but some analysts believe much of what we're seeing is unnecessary hype. >> near-term goal is to deter independence. china has largely achieved that goal. and i don't believe that the chinese are likely to use force within the next few years. i think they do not want to pay the price. >> reporter: whatever the intention, former navy captain and u.s. intelligence officer carl shuster says china's messaging is clearly directed to a specific audience. >> they want the american people and the american government to see the cost of help ing taiwan as exceeding the benefits. >> reporter: you well know, captain, you're going to have americans who will look at this and they'll say, why should americans be involved in anything over there? why should they care what's happening with taiwan? to that, you would say. >> if you won't defend a 70-year partner from violent aggression, other countries will look at it and believe we are either not capable or not willing to sacrifice anything for them. >> reporter: no question, wolf, it is an increasingly uneasy situation for the u.s. and its allies in this region. while we continue to talk about rising tensions, we should also say there are points of cooperation and even collaboration between the u.s. and china. that's going to play out here in shanghai in just 24 hours. we expect john kerry, serving as a special envoy representing the biden administration to be here, to discuss how the two countries can work together to combat climate change. so one area where they are seeming to work together. >> we'll see what happens on that front. david culver, excellent reporting as usual. thank you very much. police resignations in the wake of a fatal shooting of a young african-american man. the latest on the outranl over the death of daunte wright. tart. we didn't stop at computers. we didn't stop at storage or cloud. we kept going. working with our customers to enable the kind of technology that can guide an astronaut back to safety. and help make a hospital come to you, instead of you going to it. so when it comes to your business, y get exactly whatp you want on wayfair. hi. last piece.s t-kelly clarkson?
