an urgent search under way right now in the atlantic association after a submersible that takes people to see the wreckage of the "titanic" goes missing. time may be running out for those on board. we have the latest. plus, all talk or a turning point? critical meetings wrapping up between the u.s. and china. what we know about any progress and the sticking points straight ahead. another u.s. federal agency revealing a possible data breach, potentially the latest hack in a major global cyber attack. millions of americans' personal data exposed. well are following these major developing stories and many more all coming in right here to "cnn news central." ♪

>> we begin with an urgent search and rescue operation that is currently under way in the atlantic ocean. right now officials are racing to find a submersible operated by a company that runs tours of the "titanic" wreckage. officials say this was reported overdue on sunday and is said to have only 96 hours of survival time. we're told several government agencies and deep sea companies are working on re-establishing contact with this submersible. cnn's miguel marques is joining us now live with more details on this. miguel, what do you know at this point? >> yeah. the company that runs this operation ocean gate expeditions does everything from, you know, science, under water to photography and video to -- to tourism as well to places like the "titanic" wreckage and have done it for quite some time. it costs about $250,000 per

person to do this. what we don't know is exactly who was on this submersible. it can hold, if it's the one it a they have up on their website, it can hold up to five people. it has 96 hours worth of air, but it all depends on how many air are on that submersible and how deep it is. we know that the u.s. coast guard along with canadian air force as well is assisting in this. they are all moving to this area by fixed wing and boat trying to get to the area so that they can help out. but, look, this is extremely remote. these depths are incredibly deep. the "titanic" itself is about 38 up meters. that's about 13,000 feet upped the ocean. just extreme, extreme remote and difficult place to operate on a good day. the canadians do have a p-8 or poseidon aircraft that has the opportunity see underwater. it's a sub hunting aircraft that can see under water to some

degree but it's not clear if they know where this craft is and what exactly happened to it. as you mentioned, they have about 96 hours of air in sort of a perfect conditions, but it's not clear given that this was reported missing 24 hours ago now. how much more air they might have and where this search goes for now of the right now all hands are on deck trying to find this crack. brianna? >> miguel, thank you for the very latest. want to turn to an expert on this. we have butch hendrick here with us. butch, have you 30 years of experience as a rescue diver. you're also the president and founder of lifeguard systems which is an international rescue and recovery training company. do you know where you begin with a rescue like this? >> well, i think the same way that the united states and going and the canadians will be working, the first thing is to

discover is does the unit, the submersible have releasable beak ops, emergency beacons, so if it does, then would have possibly released a beacon or two to the surface so that there could be tracking signals, a signal coming off that have that our coast guard, the canadians, the brits would be able to pick up and then be able to start to track where it might have come from. we'd be looking at what has happened in the last 48 hours to the weather what, conditions may have change that had are not normal, what would have happened with the currents at the depths and in between the bottom at 12,000 plus feet. could a current have suddenly taken or overrode the power of the unit, the submersible that's down. next would be the proper submersible should have a beacon

or two that should be attached to it that could be sending out an underwater signal would tell people how to find it so they will be looking for those, looking at the weather and tracking what would have happened to if it got taken off of the site. the coast guard will certainly be doing something very similar, and it will be coming in with their own trackers. if they find a beacon that was released from the submersible, they would see where it was, track the weather and put another one of their own in the water and track it and see how it would go and where the possibilities would be. i know that listening to one of the admirals the coast guard is coming in with their lower end shallower water sides, sonar units at the moment with larger more capable pieces of equipment behind it, and using side scan based on the debris field, you'd have to have a beautiful mapping

sequence of the entire wreck that could be a layover, if you will. we would be laying one on top of the other in order to see what's new, what is there that we didn't see about. the potentials, up, that the unit has not had the power to maintain with the current. more likely based on the original videos and original things that bob ballard did with the "titanic" is that it's maybe caught on something. >> and, i mean, these are huge concerns, butch, obviously. so we do appreciate your time as we have so many unanswered questions at this point. quite frankly we're trying to get more details about those who are engaged in the rescue here. butch hendrick, thank you very much for taking the time with us this afternoon. we do appreciate it. boris? >> another major headline we're following this afternoon,

progress but no breakthroughs. right now u.s. secretary of state antony blinken is heading back to the united states set to brief president biden after a weekend full of meetings with top chinese officials, including a brief meeting, 30 minutes with president xi jinping this morning. after talks the secretary said that leaders agreed on the need to, quote, stabilize the two nations relationship but also stlad's still key issues that remain unsolved including rights tensions over taiwan, spying, china's support to russia and trade, just to name a few. cnn's apnea koren is here with us. seems like both sides are ready to express optimism but also to remain skeptical of each other. >> reporter: yeah, that's right, and that remains the case, but, look, boris, this was all about re-establishing lines of communication, and that has been achieved. we have to remember the

relations between china and the u.s. are at an all time low. we didn't even know if the u.s. secretary of state ablinken was going to in fact meet with the chinese leader xi jinping but that did happen, and the fact that that took place is incredibly important. we heard from the chinese ministry of foreign affairs after blinken departed, and they said that his visit marks a new beginning in bilateral relations. i mean, this is very optimistic language coming out of beijing, but there was one thing that the united states want the other than re-establishing lines of communication which was military-to-military communication. they have been near misses between the two militaries, particularly in the past month in the south china sea and taiwan straight with a fighter jet and most recently enabled warships, and a mishap like that turns into an armed

confrontation very quickly. the chinese, you know, obviously don't want to give legitimacy to u.s. activity in their backyard, but we also heard is the reason they denied that military-to-military communication is because of the u.s. sanctions on the chinese defense minister over the purchase of russian arms back in 2018. but why don't we have a listen now to antony blinken talking about the importance of those communications. >> i think it's absolutely vitethal we have these kind of communications military to milt. that imperative i think was only underscored by recent incidents that we saw in the air and on the seas, and at this moment china has not agreed to move forward with that. >> reporter: boris, lots of issues were raised. obviously no resolutions there, but the shown that this visit will pave the way for the visits

of the u.s. treasury secretary, the commerce secretary in the coming weeks. we heard from the white house as well, and they said that this meeting was a good step forward. boris? >> and potentially one eventually between biden and xi himself. anna coren in hong kong. thanks so much. >> both sides are claiming some progress during these talks. certainly still a lot of work to do. they are touting some positive developments such as the fact that both sides are at least talking again with more planned high-level meetings in the future. blinken says china said it would not give lethal aid to russia for the war in ukraine. they both agree on working together to shut down the flow of chemicals that create fentanyl, of course, contributing to the opioid crisis here and they also want to cease non-stop flights between the two countries. there are, however, major sticking points. no agreement on military to military communications, continuing disagreement over the

future of taiwan and also human rights and trade consistently through this relationship had been at issue. the chinese president said the following which seemed to give a sense of the mood here. i hope that through this visit mr. secretary, that is blinken, will you make more positive contributions to stabilizing u.s.-china relations seeming to put the onus on it, on u.s. officials to improve the relationship going forward. why are those military to military communications key? was that a u.s. goal here? you may remember a few weeks ago a chinese jet flew right in front of the nose of a u.s. recap sans jet, this just off the coast of china here, but in international airspace quite a dangerous encounter there. you'll see them and it even shutters the cockpit as it went by and then chinese warship steering a couple hundred yards in front of a u.s. destroyer in the taiwan straight, again, a

dangerous encounter. that's why you want a military-to-military communication so incidents like this don't esclaim. i want to bring in the retired former supreme allied leader of nato dr. wesley clark. always good to have you on. >> thank you, jim. >> first the positive developments are, the biggest one is that they are talking and they weren't, and this visit was cancelled at the time that the chinese balloon went over the u.s. if you had been staffing this visit to beijing, would you consider it a success? >> yeah. many as far as i'm concerned, this has been a really good visit. the united states has done what it needed to do to reach out and we should feel good about this. on the other hand, there's a very long way to go in this. >> so those are the good things, and by the way talking matters better than anyone geffen the seriousness of the sizies between these two countries.

sticking to the points here, military-to-military communications, we've been describing the encounters we've seen with greater frequency between u.s. and chinese forces in the region. how important it would be be to have military-to-military coms to help prevent escalation? >> i think it's critically important from our perspective but apparently not from china's. i think china wants to withhold some of that with leverage and moving these talks forward and getting some concessions from the united states. you know, jim, the whole tone of this is this -- this visit by secretary blinken followed bill gates' visit and other big businessmen, elon musk in china so it's clear that china is trying to use the american-chinese business connection and looking at the american government as being politicized in this, so there's pressure on our government to move forward. >> the let's talk about taiwan here because this is arguably

the most intractable of the issues between them. i just spent the last week in taiwan. spent time with taiwanese military there doing exercises to prepare for chinese invasion. what is the way forward to prevent conflict here pause you really have two red lines crossing each other, the u.s. red line being do not take military action against taiwan and, of course, taiwan's red line is they don't want talk to become more effectively independent which is the way the government operates and the economy already operates. what's the way forward to avoid conflict there? >> i think the way forward is developing more mutual interests between the its and rite rick and on the chinese side slowly let it resolve. work with the taiwanese and show

friendlier relations with taiwan and maybe relax a little bit in hong kong because the example of hong skong a very bad example. from the american side we've made our position pretty clear, and we're not going to be able to tell the taiwanese people or their government go ahead and surrender to the chinese, and we're not going to tell them to start a war, so we're sort of in a difficult position here. it's really china that's the demand doer here, a they have got to back off. >> up thing that struck me during my visit to taiwan is that the taiwanese feel somewhat caught between the superpowers here, and there is some concern among some officials that i spoke to there that not just china inflaming the situation but also some folks in the u.s., particularly with this one upmanship that you'll really see among some in both parties in terms of it being tougher works can be tougher with the relationship with china? who can talktive on the issue of

taiwan? is there concern that the taiwan issue can be stoked and escalated from the outside? >> well, i think we have to be careful how we look at china and particularly the china issue. it's always been a hot button issue with the republican party going back to the relations with chiang kai-shek and relationships with the republican party. there's always been ambiguity, and over the past step years the u.s. rhetoric against china has escalated. we're doing planning against china in the pentagon. we're budgeting and buying forces to be able to deter china. got to be careful not to just make a self-fulfilling prophecy in that case. really we have one fight we have to help ukraine on and that's a critical fight for the future of the world. china not necessarily so. so a lot rides on what the united states does with ukraine,

and if we support ukraine and ukraine flounts that soviet aggression and takes back most or all of its territory, there's a settlement there that's satisfactory, this would also cool off the situation in taiwan. >> and one thing all sides seem to agree son a conflict over taiwan would be devastating for all involved, chinese forces, u.s. forces and the taiwanese themselves. general wesley clark, always good to have you on. thank you so much. >> thank you so much, jim. >> brianna. still ahead, a new order in former president trump's classified documents case. what a federal judge says he can't share with the media or his supporters. and more details about the cyber attack that could have spilled your financial information and a florida deputy with 30 terrifying seconds underwater

classified documents case. that means no talking about or posting any of that information. the same goes for his close aide and fellow defendant walt nauta. somehow this going to impact the former president? >> well, boris, it places a are strikes on him. he's a criminal defendant land have to follow the judge's rule. this is a pretty procedural thing. you see it in almost any case that's going to be going to trial where the judge steps in and says the skwld tjustice dep will turn over all evidence that could help you, hurt you and we'll put a protective order on it and say you can't share is widely before trial, real typical, but it is something that if it isn't followed by the defense, by the defense lawyers, by the witnesses they are talking to before trial, that it would be punishable by contempt of court or other things if he doesn't follow the rules. last week question see in court his attorneys were a little

concerned about this idea of placing restrictions on him, what he could talk about to other people in the case, and now there is this court order that the judge has put on this case saying donald trump shall not retain copies of the evidence, discovery material, cannot have notes for his -- for himself that he takes about those things. have you to turn those notes back over to the defense team and also cannot be sharing things that's learning that's evidence in the case to the public or news media or sharing them on social media platforms specifically, so we's going to have to follow the rules. >> which the former president has done before. he shared all sorts of details on social media before even the legal aspect of this has publicized information. >> and allegedly the classified documents as well that he took after his presidency. donald trump and paper has not always played as nicely together. >> thanks for the update. brian mah.

were some new indication that had had a global cyber hack be bigger than thought? an investigation of a possible data breach of a contractor which is believed to be part of a broader hack that's hit multiple federal agencies. u.s. officials are blaming russian cyber criminals for this. cnn national security reporter natasha bertrand is joining us now. tell us what you are learning about the information that's been compromised. >> yeah, brynna, what we're hearing is they are essentially still investigating what's been taken by the russian cyber criminals, but what the department of agriculture is telling us that they do understand that a small number of employees have had their data taken and that those employees will be contacted for any kind of data protection steps that they need to take. they say it doesn't seem overly significant at this point and they are still looking into it and we also have, of course, the department of energy locking into the breach of two different nurse inside the d.o.e. we have oregon and louisiana,

the motor vehicles department, millions of people in those two states have had their data compromised, real anyone with a driver's license now has their data posed because of this hack, and we also have the office of personnel management which says that it is investigating a breach. cnn reported last week, of course, that the russian hackers are believed to be responsible for that attack as well. if you recall opm had that massive hack back in 2015 so this is not welcome news for them. in terms of who is behind this, we do believe according to our sources that it is a russian-speaking group that's pretty well versed and experienced inrance comewear so they have been asking their victims for in some cases multi-million dollar ransoms in order to get their data back. here you can see on the screen a few more of the victims who have been targeted in this hack including the bb kris, british airways and major universities including johns hopkins and the university of georgia. all of these are subject to be

extorted by these hackers. in one case a source told my colleague seanlingus that the hackers have demanded a $100 million ransom from one corporate company that. company apparently told the hackers that that was an absolute non-starter, but this goes to show how massive a hack and how devastating a hack can be when one part of a software used by so many different entities is compromised and that's apparently what happened in this case. >> in the health systems, real world organizations is hospitals and universities and this is awful, and i fear that i'm going to see you again with more updates on this. natasha ber shand. thank you. dangerous heat in texas and the south. it will feel like 2120 degrees outside to some as several cities are still cleaning up from storms that have left thousands without power, without air conditioning as well. what forecast remembers expecting just ahead. okay everyone, our mission is complete balanced nutrition. together we provide nutrients to support immune, muscle, bone, and heheart health.

right now, president biden is headed back on the campaign trail. he's flying to california for a three-day trip to highlight the environment and meet with donors. the president officially kicking off his re-election campaign over the weekend rallying with union members in philadelphia. the 2024 election is still more than 500 days away, and polls show that some democrats do not want him to run again. he's also facing a democratic challenger, including environmental lawyer and anti-vaccine activist robert f. kennedy jr. who is posting

surprisingly strong polling numbers. cnn's political director david chalian joins us now. what is the polling saying about the democratic side of this race? >> well, you know, our most recent poll had robert kennedy jr. at 20% support. your eyes sort pop and whoa, here's an incumbent president. why is a challenger at 20% support. obviously name recognition has something to do with that. his name is robert kennedy. not a bad credential to start with just for democrats, but when you look inside our numbers, not all 20% are meaning the same thing. his support is coming largely from independent more moderate conservative democrats, right? that's not the base of the party that shows up as majority in these primary and caucus contests so he's not pulling right now from the folks in large numbers that -- that turn out and show up in these primary cop tests why suing a path to actually taking biden on for the

nomination is also a trick one. >> i was also surprised by 8% for marrian williamson. how much of this has to do with the president's age? >> the president's age if he runs and wins again is a concern. if you talk to any democrat, any president in the biden campaign, this is not something they ignore. this is the reality they are dealing, and you heard, you hear them on the campaign trail a bunch, the way in wit white house is addressing this right now saying, hey, yes, i'm old, but i've got a lot of experiment and wisdom and look at all these things that he's got done and he also says watch me. that's what people will do over the next year and a half, they will watch him very closely and whether or not he has the vitality and vig tor do the job and bring on the confidence of the american people will be one of the questions he has to answer.

>> a lot of self-deprecating humor on the campaign trail so far for president biden. it works to make him somebody that people empathize with, but is there a chance that rfk jr. could steal a primary state? >> as you know, president biden rejiggered the democratic calendar to get south carolina, a place he did way, that sort of catapulted him to the nomination up front. if he doesn't play hard in iowa and new hampshire somebody might come there and make some hay. we armed the four recent polls in poll of poll and joe biden's approval rating while low overall is among democrats 82%. that's not a terrible spot sgland part of the reason for that change in the order of primary states was the snafu we saw last time around to start in iowa. >> yes. >> i also want to talk about the republican side of the presidential race and play some sound for you and react to chris

christie that his support for a support pledge is pointless. >> look, i think the pledge is just a useless idea. you know, we're republicans and the idea is you would support the republican whether you won or whether you lost and you don't have to ask someone to sign something. only in the era of donald trump that you need somebody to sign something on a pledge so i think it's a bad idea. look, i will do what i need to do to be up on that stage to try to save my party and save my country from going down the road of being led by three-time loser donald trump. >> i've not heard any other republican go out against the former president that strongly. >> he's making that his calling card of the campaign. no doubt chris christie sees himself in the role as the guy inside the party to really try to take donald trump down. even if he's not the one that ends up with the nomination. >> right. >> but the last thing he said,

boris, i will doll what i need to do. i read that to say that he's going to sign that pledge because he doesn't have a life in this campaign without getting on that debate staple but may not honor the pledge that he signs if donald trump is the nominee. >> if he makes it to the debate stapling. we eve seen him cause fireworks. fun to watch those two go head-to-head >> jim? >> summer does not officially start until wednesday but don't tell that to 35 million people from mexico all the way to mississippi. they are under scorching heat alerts and some can feel dangerous triple-digit temperatures. cnn meteorologist chad myers here to discuss. how wide is this area in. >> this should be mid-july, certainly not mid-june. we're a month ahead of where we should be all across the west and the deep south, of course, this is where the worst weather is, 80 plus possible heat

records, broke a couple yesterday, excessive heat warnings all the way from new orleans all the way back to new mexico and all the way down to the rio grand. san antonio is going to feel like 105 without the humidity and then you add the humidity in, and it will feel even worse. look at corpus christi. in the heat and sun it could feel like 120. even for dallas, it's going to feel like 116. so these are heat and humidity numbers here, not thermometer numbers where you're sitting in the shade, but all of the numbers that i'm showing you are in the shade. you multiply that by a little bit if you're sitting in the sunshine or working in the sunshine across all of texas. this is making a couple more things go on here. tornadoes and severe weather across the deep south where the very hot air is clashing with cooler air in the north coast. this sliding area of a frontal system is causing severe weather. even a tornado warping and i saw some damage that i'm look at on the radar, 20 minutes.

a big headline that we're watching here on cnn "news central "swat submersible used to take people to the "titanic" wreckage is missing off the coast of newfoundland. an urgent search-and-rescue effort is currently under way. the company oceangate expeditions issued a statement saying our entire focus is on those individuals in the submersible. the u.s. coast guard confirmed they are looking for five missing people. what's unclear is we don't know how much oxygen they have left. we'll have an update minutes from now. jim? >> it is a measure of height and

weight that some consider a scarlet letter. doctors have used bmi or body mass index for decades for health assessments and now the american medical association is warning that that figure has significant limitations with a history of use for, quote, racist exclusion. cnn medical correspondent meg tirrell is here to explain. meg, this is something we hear about in our doctor's offices, right, something that relates to your height and weight, heard it for years. what has the ama found about the limitations with this number? >> yeah, jim. this is really an extra push to a movement that's been going on for a while, looking at mbi not as a great measure of individual health risk. a metric invented in 1832 by a belgian statistician trying to characterize the average man. it wasn't until the 1970s it was adopted as a marker to measure

body fat measurements across the population. it can sometimes be used for individual health ridge of the ama in a statement last week it significantly correlated with the amount of fat mass in the general population but loses predictability when applied on the individual level. that's really the issue here. this is really validated in a population that is mostly white, validated in the 19307s and a population of mostly men and this really isn't applicable across people of different racial backgrounds and people of different ages and sexes so there are major problems with this. the problem with that though is that this is used and not just a screen for being overweight or having obesity but also eligibility for certain medical procedures like fertility treatments or having certain surgeries. can also play into life insurance rate but this is something that doctors say deserves a lot more scrutiny. >> so the ama is saying it has some relevance across the population but not predictive

for individual health outcomes necessarily, so is there an alternative that we should say ask our doctors about when we go to see them the next time they take our height and weight? >> yeah, doctors have been tell me you can use bmi perhaps in conjunction with other things. other things they look for are evidence of visceral fat, fat around the organs because where you carry fat on your body has a lot of implications for your health. waist circumference is another thing to look for and doctors are really concerned with markers of metabolic syndrome so that's what they are on the lookout for. >> meg tirrell, something to keep track of. bories? >> still to come, americans across the country celebrating juneteenth, commemorating the emancipation of enslaved african-americans in the united states. what the holiday means for so many straight ahead.
