also breaking this morning, signs that the labor market, which has been stunningly strong for so long is now cooling. fed watchers and wall street very warily awaiting these numbers. i'll talk to acting labor secretary julie su for her take on the numbers and the strength of the u.s. economy. and later, more heat for an already weather-weary nation. over a dozen dead nationwide from the high temperatures. >> i have asthma, so the air quality is really hard on my lungs, and then with the heat on top, it's like having a meltdown all in one. >> when could we get some relief from the brutal and record-breaking heat? let's begin with the war in ukraine and the breaking news. we've now confirmed that the u.s. will send cluster munitions to ukraine. these are large bombs containing smaller explosives inside them which then disperse and can kill in record numbers. these weapons are so dangerous that more than 120 countries

including many u.s. allies have agreed not to use them, but ukraine says they are desperately needed. joining us now nbc's kelly cobiella from ukraine. also with us msnbc military analyst colonel jack jacobs. kelly, why does ukraine say they need these cluster bombs so badly? >> reporter: ana, we've talked about these russian defenses that have been built up over the past several months, over the winter and into the spring. we're talking about large mine fields and then layers of trenches where the russian troops can hide and fire on advancing ukrainian forces. the ukrainians say these types of munitions will allow them to hit more targets with one rocket, essentially because of the way they work. you can fire them at trenches, hit more targets, more opposing forces, and that will help in their advancing across those

enemy lines. another benefit is you can fire them more quickly because you don't have to have a precise target. you're going to have a wider spread of explosions with these type of munitions versus artillery. they're also low on artillery, so they need more weaponry, they say. you've outlined some of the challenges, the fact that some of these bomblets remain unexploded and are a massive threat to are troops and civilians. the ukrainian troops say, look, we will use these in a targeted way. we will not use them in urban areas and on top of, that they say it is our land. we should have the choice of deciding how to use them. and it is a difficult choice for them, ana, because in their view with the way this counteroffensive is going, it's either use something like these cluster munitions to have a bigger impact on the battlefield

and then deal with the cleanup down the road to protect their civilian population, or don't take back that land at all. that's the kind of decision they're having to weigh. ana. >> colonel jacobs, your reaction to the u.s. sending these cluster bombs and what it means for the battle. >> well, you know, the ukrainians have been using them for some time, just not ours. and of course the russians have been using them since the beginning of the war. the important thing here for the united states in making the decision is not how it's going to turn the tide of war because it probably will. it will make it easier for the ukrainians to attack large formations of russians who are in linear defense, extremely difficult to attack otherwise, but the relationship between the united states and its allies. all of the american allies have signed the agreement not to use cluster munitions. >> right. >> and the principal reason is that there are lots of duds, about 2% duds from the american

munitions. by the way, about 40% for the russian munitions, and so after the war it's extremely difficult for civilians and also for troops in the area. how the united states deals with our allies with respect to giving these munitions is going to be the critical thing, but there's no doubt about fact that it will -- these will assist the ukrainians in prosecuting the war against the russians, kelly. >> so explain, though, why they would make this decision now. what do you think the tipping point was, colonel? >> well, ana, the problem here is that the ukrainians are running out of ammunition. this is an extremely ammunition intensive war. they need artillery rounds, rocket rounds, and the mechanisms for sending them off, but they also need the ability to attack formations of russians, and they don't have that. they're running out of that very

quickly, and their ability to replenish them is insufficient to get them the kinds of munitions in the amounts they need in order to continue the counteroffensive. so the ukrainians are -- desperate's probably too much of a word. they are desperate to get large quantities of indirect fire, artillery and rocket ammunition, ammunition such as these cluster munitions to support their troops in the counterattack. without it, it's going to be extremely difficult for them to oust the russians from the areas they're attacking now, ana. >> colonel, a separate subject here. there was yet another close encounter high in the sky with russian jets and u.s. drones. what message is russia trying to send here? i should note, this was in syria. >> yeah, you know, we have a base in syria about 100 miles from damascus. we've been there for quite some time. we're using it as a base to attack formations of isis and

isis headquarters. we have between 8 and 900 people in the country at any given time. the russians don't want us to be there, obviously, even though they're opposed to isis as well, but they're just trying to make life difficult for the united states and its allies, given the russian attack in ukraine. this is far from ukraine, but it still demonstrates how important the russians feel about making it difficult for the united states. these kinds of things -- these kinds of harassments will continue. they're liable ultimately to be some sort of catastrophe with a russian plane colliding with an american vehicle, but for the time being, these things will continue. >> okay, thank you so much. colonel, jack jacobs and kelly cobiella, create talking to both of you. now, the short lived but massively consequential rebellion led by yevgeny prigozhin has caused the mercenary chief's reputation to

turn from hero to traitor. keir simmons was granted rare access to a new base in belarus meant to house up to 5,000 of prigozhin's forces but now sits empty. belarus's president insists per prigozhin is not in belarus. here's a preview. >> of course we're talking about yevgeny prigozhin now because he just took an army of mercenaries and marched them toward moscow, and shockingly, met very little resistance along the way. but prigozhin has a long history of doing sensitive, off the books missions for the kremlin, including targeting the 2016 election with a disinformation campaign to help donald trump. multiple u.s. intelligence agencies have concluded that putin wanted trump to win the

2016 election. but intervening directly was a risky proposition, even for the kremlin, so prigozhin catered to the boss. prigozhin didn't just have the wagner group, the private contractors fighting in syria, he had another side business. it was a troll farm that pumped out online disinformation, mostly against russian dissidents. he now turned his keyboard warriors against the united states. >> he in some ways contributed to kind of the narrative that grew up around hillary clinton, and donald trump. >> using facebook, using twitter, using other kinds of ways to try to manipulate information inside the united states to try to help mr. trump win the election. >> prigozhin had been a jack of all trades for president putin with a bot farm churning out disinformation and his army of mercenaries. it all made him powerful enough or believed he was powerful

enough to challenge president putin. >> thank you so much to richard engel, and on assignment with richard engel, revolt from within premiers tonight at 11:00 eastern here on msnbc. we'll also be streaming on peacock. now to that breaking news on our economy this morning, in june, the u.s. added 209,000 jobs with the unemployment rate now at 3.6%. this marks the slowest month for job creation since december 2020, and let's take a look at how the markets are reacting to the news. you can see down slightly, the dow down 40 points right now. joining us to discuss an nbc news business and data reporter brian cheung, and roben farzad host of public radio's full disclosure. brian, kick us off. >> not only was it one of the slower months but it fell short of wall street estimates. they were expecting around 230, 240 thousands, came in around

209,000. in may it was 306,000. the unemployment rate is at 3.6%, which is still essentially near 50-year lows. the black unemployment rate went up to 6%, so something that we're going to continue to keep an eye on in coming months. where do we see the job gains in the economy? if you break it up by sector, leisure and hospitality, bars and restaurants adding 21,000 jobs in the month, professional business services, the white collar jobs that could in some cases include some tech jobs actually adding jobs. 21,000 in the month. so maybe the bottoming out perhaps of some of the layoffs we've seen in some of those sectors. interesting to look at retail trade. these are jobs at the mall, for example, contracting by about 11,000 jobs, which shows maybe the bifurcation in terms of some industries seeing job gains, whereas others are losing them. but again, overall seems to be positive that we got job gains in the month of june and with the unemployment rate still low, jobs picture very much looks very good. >> okay.

so roben, this was a lower jobs number than expected. how do you read it? >> i think that it's kind of a non-release other than the wage data, which might give the fed more ammunition for at least one more rate cut, probably two, you know, following in september. having said that, and this is an ongoing theme, when does the fever break. how many rate cuts do we have to push through to see trickling job gains or contraction in job gains. can you land this economy perfectly without any sort of recession. i'm doubtful about that, but i think the fed not worried so much about job formation right now. it would trade some unemployment for lower inflation because it's really not close to its 2% inflation target. >> brian, roben does mention wage growth. what's happening there? >> let's unpack the number. it worked perfectly that we have this prepared. 4.4%, that's how much more people were getting paid in terms of wages in june of this year compared to june of last year. if you look at may to may, it

was 4.3%. i want to point out it's a lot slower than the 5% job or wage growth that we had seen in the earlier parts of last year. now, to roben's point, it might sound a little bit weird for economists to say we actually want job wage growth to decline. the reason why is because, again, do the ultimate employers pass on those costs to customers by raising prices as they raise the wages for the people that they employ. seeing this number go up might be one reason why the fed says maybe we have to further slow this economy by raising interest rates even further beyond the ten times they've already done so. that's the reason markets are also pricing in the odds of one more interest rate increase in their next meeting later on this month. >> brian cheung and roben farzad -- oh, go ahead. >> the other dimension is how long they keep them this high. you could just keep them at that level. you could talk about a terminal rate, but if we kind of impregnate this economy with

high interest rates and let this continue into 2024, i don't think many people were pricing that in. >> good point, thank you so much for adding that context to all of this. i appreciate you, roben farzad, thank you brian cheung. let's bring in acting labor secretary julie su to talk about this. thank you, madam secretary for being here. what's your biggest takeaway from today's jobs report? >> thank you so much. good to be here. >> what's your takeaway from today's jobs report? >> so this is a good jobs report. this is, you know, an indication of steady and stable growth combined with the 3.6% unemployment rate. remember our predictions were that it would not go under 4% this quickly, so it is a sign that biden's economic policies, that the president's vision of the economy is working. we are on track, but the 3.6% is the 17th consecutive month of less than 4% unemployment, which is the longest duration since the 1960s.

this is a good jobs repor of steady, stable growth. >> economists had been predicting a cooldown with increased unemployment, the labor market continues to show this resilience as you point out. so are we in the clear for a big spike in unemployment? >> well, i think that the other thing that we see is great confidence in the economy, right? we have seen that labor force participation rate reach pre-pandemic levels across the board. for women, it is the third straight month of the highest labor force participation rate for the prime age working workers, 25 to 54, in 75 years. so women are doing our part. workers are in the labor market. jobs are growing and i think these are all very much core to president biden's vision of the economy, what we call bidenomics. >> so are you safe to say no recession? >> well, i'm not going to make predictions, but i will say

that, you know, we've also seen inflation come down, right? inflation is now half of what it was a year ago. so i think altogether we are seeing that president biden's vision of doing three things, investing in america including industries like semiconductor, infrastructure, manufacturing, clean energy, also investing in american workers and also increasing competition to decrease prices that those things taken together are working and we are seeing both economic security and growth in our economy. >> markets are reacting to today's news, still down slightly this morning. wall street expects another interest rate hike. mortgage rates are already way up. credit card rates are up. this is hurting a lot of americans. what's the answer? >> i mean, i think that's right. we should acknowledge some of the pain that americans continue to feel, right? remember, just three years ago we were deep in a pandemic, and the economic catastrophe that

associated -- you know, that came with it. i think part of the answer, though, is to continue to do what the president said. let's finish this job. let's continue to create good jobs and communities across the country. let's create pathways so people who have been left out of the labor market before can get those good jobs, and let's continue to focus on bringing down inflation, bringing down cost of living so that americans can feel this in their homes at the grocery stores and at the kitchen table. >> acting labor secretary, julie su, thank you so much for taking the time today. appreciate it. when we're back in 60 seconds, summer scorcher, temperatures expected to hit triple digits in some areas again today. what this hot and humid weather can do to your body. plus, an alzheimer's breakthrough, the new drug just approved to slow down the disease. and later, the social media showdown between twitter and threads, that rivalry now hitting a boiling point. valry no

we're back and turning towards the heat, baking the country, 9 million people under heat alerts with more record breaking temperatures predicted in south florida. this combination of heat and humidity really ringing alarm bells for scientists who warn heat is the number one weather-related killer. joining us now from secaucus, new jersey, is nbc's emilie ikeda. this weather this summer has kind of thrown us all for a loop. how are people dealing? >> reporter: absolutely. ky tell you that the heat and humidity is absolutely setting in here today, parts of the northeast will see temperatures above 13 degrees above average temperatures. now, fortunately, the northeast is seeing a slight improvement today compared to the record setting temperatures we saw yesterday, but the oppressive heat will continue hovering over other parts of the country, and we've seen the dangerous and even deadly impacts. in arizona, the u.s. border patrol releasing video overnight of a rescue that happened a

couple of days ago. two hikers in the arizona area, keep in mind they've been experiencing triple digit temperatures, they were experiencing heat stress. and because of the difficult terrain there, they used a blackhawk helicopter to hover over, hoist those people up and into safety. however, other people haven't been as fortunate. at least three possible heat-related deaths playing out across the country so far this week. and between the scorching heat and also some of that poor air quality we've seen throughout the week, residents in the area have described it as a one-two punch, especially those who suffer from underlying respiratory conditions like asthma. another good point of good news here today, across the country air quality conditions do seem to be improving this morning. you will also find some relief on the roadway travel, as people start to head back. you can see the roads behind me there moving pretty smoothly after 43 million people got behind the wheel for this july

4th week that has really been marred by a week of weather woes, really ana. >> emilie ikeda, let's hope there's some relief coming quickly. appreciate it. now for more on the health risks of this extreme heat, i want to bring in pulmonologist and nbc news medical contributor, dr. vin gupta. doctor, always in this case to see you. can you just talk about what exactly happens inside the human body when it faces this kind of extreme heat and what the specific health risks are. >> ana, good morning, thank you as always for platforming these issues, vital. so for all your viewers, what happens, the body anytime it's hot and humid outside is trying to sweat. it's trying to pump as much blood, the heart is trying to pump as much blood to the surface to your skin to evaporate to sweat to cool down. what ends up -- the big concern here is that it can't do that effectively because say somebody has an underlying heart disease or there's another condition that preempts them from doing

that, confusing can set in. signs of heat stroke include -- and i think we actually have this up for your viewers, confusion, nausea, vomiting, hot skin, your body is -- the surface temperature is very hot. you're developing a fever, fast heart rate. that heart's working really hard, heavy sweating. those are the signs of heat stroke, confusion in particular amongst kids and elderly that we have to be vigilant for. check your neighbors. that's what the body's trying to do to compensate. sometimes it can't. >> i come from colorado where it's a dry heat and then now living in the northeast, you really feel that humidity. it makes it feel extra hot. is hot and humid more dangerous than hot and dry? >> vital that you brought this up, it is. hot and humid, far more dangerous than hot and dry. that humidity, ana is key. if it's too humid, for your viewers out there, google wet temperature. that is a combination of how hot it is and how humid is it.

the more humid it is, the less able it is for your body to sweat, for body to leave the surface of your skin into the environment, the atmosphere. the more humid it is, the less able you are to effectively cool off. >> so what can people do to protect themselves? >> a few things, and i think we have another graphic here. in terms of ways to keep yourself safe in a heat wave, first and foremost, shelter. you don't have air-conditioning, get as low as possible in your residential unit. if you have a basement, fantastic. keep your windows open at night. if you have ac, clearly just make sure you're changing out those filters. run your ac, sunscreen is critical, spf 50. if you're misting your skin, replace sunscreen every few hours. wear a hat. even if you have hair, wear a hat. it's going to protect you if you have to be out in the sun, especially if you have a job that requires being out in the

sun. stay vigilant for signs of heat exhaustion and heat stroke. again, confusion is a key sign, especially in kids and folks that are elderly. critical to keep that in mind. stay hydrated, especially with electrolyte rich fluids like gatorade. one way to know if you're hydrated is how much is going out of your body. how dark is your urine to be as medical about possible about this. >> all really important, potentially life-saving information you're providing there. i read one maybe short-term tip to cool down is to use mouthwash or drink peppermint tea or something with menthol because of that cooling effect and so i just throw that out there as like a little maybe trick in the short-term, not long-term, but that was another one i thought was news you could use. dr. vin gupta, thank you so

much. we'll see you back here later this hour. how soon the probe into who brought cocaine into the white house could wrap up, and new details about where it was found. plus, gop infighting, did congresswoman marjorie taylor greene just get booted from the freedom caucus? felt more energy in just two weeks. uh... here i'll take that. -everyone: woo hoo! ensure max protein with 30 grams of protein, one gram of sugar. enter the nourishing moments giveaway for a chance to win $10,000. wayfair has nice prices giveaway for a chance to win so you can have nice things. hah! kelly clarkson, we have a kid... and harold. wayfair's got just what you need... performance fabrics, stains don't stand a chance.

a bag of cocaine in the west wing could wrap up by monday officials tell us, and nbc news is learning the exact location where the baggie was found. in a storage cubby located near the west executive entrance. this a highly trafficked area used by officials, staff, and some visitors. let's bring in nbc news senior white house correspondent kelly o'donnell who's been working her sources. kelly, first, who has access to this area? >> well, in many ways, ana, this is a working entrance and exit for the west wing as compared to the more ceremonial ones that

become a part of official events and are well-documented in sort of the national story of the white house. this is a ground level right off a main drive that is private, west executive avenue, where you'll get almost a whole range of visitors from the president and the vice president moving through, cabinet officials, military, staff, the people who handle the physical spaces and facilities in everything from cleaning to maintenance and so forth, a whole range of people move in and out of this area. it is not open to public tours, but the tours we've been talking about through the course of this story are private tours that are sponsored by someone who works for the white house or the administration and has an opportunity. usually in off hours after work or on weekends to bring family and guests in to see things. they would have access. that's what the white house has publicly focused on, that there were three of those kinds of tours friday, saturday, sunday,

and then this bag of cocaine, small baggie was found sunday night in a cubby. the cubbies are important because people going through that entrance are sometimes headed to the situation room or other secure places in the white house where electronic devices are not allowed. and so they store those in those cubbies off the lobby. there. >> again, this is the white house we're talking about, and i think a lot of people would assume there's close surveillance and frequent security sweeps, so why are officials saying it may be hard to solve this mystery. we may never know who ended up leaving this baggie behind. >> well, so much of the security to access the grounds is focused on preventing weapons or items that could be weaponized. so obviously anything metal, knives, guns, anything like that, but in a chemical sense they're looking for things that could be a poison, a gas, could be converted into some type of explosive. they have dogs and other sophisticated equipment that checks for that. but each of those is trained on those kinds of items. illegal as it is, cocaine not in

that category. it is not something to be weaponized per se. so that is part of the reason, and in addition, they are trying to get forensic evidence off this small baggie, and if they are not able to do that, sources are telling us it will be very difficult for them to link this to a specific person. ana. >> kelly o'donnell, thank you so much. now let's head to the 2024 campaign trail where this afternoon former president donald trump is back on the trail in iowa for what is expected to be his biggest campaign event in month and several of his rivals including his former vp mike pence have spent significant time in the hawkeye state. let's bring in nbc news correspondent vaughn hillyard, he's covering trump's rally in council bluffs and taking cover in his car because of some lightning moving through. also with us rick tyler, republican strategist and msnbc political analyst. vaughn, thank you for still joining us, making this all work. what are we expecting at this trump event today?

>> reporter: well, we're expecting donald trump to be here, but his plane is somehow going to have to land through this thunderstorm. it was two months ago when a major rally of his was canceled in des moines because of tornado warnings. today the question mark is whether he's going to show up. there's hundreds of die hard supporters who are here in council bluffs, iowa. we're in the western part of the stay. there's going to be an agricultural round table held before he gives and delivers his speech and remarks. this comes at a time in which, look, ron desantis, nikki haley, vivek ram swa my. i was talking to gave durwell i met in 2019, he was a lifelong republican but he's also very anti-trump. he wants an alternative. the quote he gave directly to me was i don't think anybody can beat trump in these caucuses, why? because there are too many people. he sees a field that is large and concerned based on

conversations within his community of other republicans that there are too many republicans. when i was following rick tyler and the ted cruz campaign back in 2015 i went back to an old article i wrote, and it was in october of 2015 in which i wrote at the time that ted cruz was sitting humbly at just 6% in the polls. so look, there is still plenty of time for other candidates to make ground. at the same time here, donald trump continues to attract despite thunderstorms thousands of events. >> vaughn, you don't look old enough to have been on the campaign trail in 2015, and i mean that in the most complimentary sense of that word. >> reporter: i appreciate that. >> so rick, vaughn mentioned pence has spent a lot of time in iowa where a voter pressed him a few days ago about his actions on january 6th. i want to play. if it wasn't for your vote, we

would not have joe biden in the white house. joe biden shouldn't be there. >> it's an issue that continues to be misunderstood. i know by god's grace i did exactly what the constitution of the united states required of me that day. i said before, i said when i announced, president trump is wrong about my authority that day, and he's still wrong. [ applause ] >> rick, how much of a factor for pence is his break with trump? >> it's got to be a factor, he's got to overcome it. i think make pence is being too nice there. he should have lit her up, and he should have said, ma'am, you know, read your constitution and then come back to me because he is clearly -- he is right about the constitution. he has no authority to unilaterally pick who becomes president or doesn't become president. this is axiomatic stuff. these are the kind of nit wits that donald trump has attracted to himself, people who just repeat things that are just demonstrably false. i think he did the right thing,

but he really needs to be much stronger on this because he's got to convince people and embarrass people when they don't know and understand their other constitution of their own country. >> and so ron desantis on the other hand has remained solidly in second place behind trump in most polls. i want you to take a listen to desantis being asked about his poll numbers on fox news last night. >> we've got a huge amount of support to be able to take the case to the people. we really haven't started that yet. we're in the process of building out a great organization, and i think we're going to be on the ground in all these early states. it is three yards and a cloud of dust type situation. >> what do you make of that answer, rick? >> not exactly encouraging. i mean, look, desantis was at one point ahead of trump, if not marginally and he demonstrated that he could beat joe biden in

a head to head. those were national polls. as vaughn will tell you, i always won by showing up, the reason trump didn't win iowa in 2016 is he failed to organize. he did not organize people to go to the caucuses and that's what ted cruz did and won. so things can change. there's plenty of time to organize. one thing is that desantis is relying on a super pac to organize. that may work or may not work, but i think that because desantis had demonstrated early positives in the polls to beat donald trump and thens that's backed way off is there's been a summary judgment on desantis, while people are looking for an alternative for donald trump, i think they've decided it's not him. a lot can happen between now and january for the caucuses. so we will see. >> yeah, so much can happen. i mean, back in 2015 it was around this time that trump came

down that elevator and no one really took him seriously as a candidate, and he went on to obviously win it all. rick tyler, vaughn hillyard, great to see both of you, thank you, and happy friday. up next on "ana cabrera reports," the first drug to slow the progression of alzheimer's, how it could transform the fight against this disease. plus, an escalating battle of the billionaires as elon musk accuses mark zuckerberg of, quote, cheating with his new threads app. ads app.

we're back with a medical breakthrough and hope for the 6 million americans suffering with alzheimer's disease. the fda has granted full approval to a drug that aims to slow down progression of the disease. this means the drug eqembi should be covered by medicare.

it is causing some controversy because of the hefty price tag and life-threatening side effects. >> it's the first time a drug meant to slow the progression of alzheimer's has been granted full regulatory approval, in a clinical trial involving about 1,800 patients in the early stages of alzheimer's, the drug leqembi slowed cognitive decline by 27% over an 18-month period, compared to people who took a placebo. >> i really cannot overstate how important today is. this is really a game changer for our field. >> reporter: the drug targets a type of protein in the brain thought to be one of the leading causes of alzheimer's. john domac was diagnosed with early onset alz's at 56, he joined a trial at the cleveland clinic receiving infusion. he and his wife ann weren't told if it was leqembi or a placebo. for the past year he's been on l leqembi. >> i've been on it for a while.

>> his cognitive function has declined slightly, they say, but not by much. >> we get that it's not a cure, but there was nothing when we got our diagnosis. nothing. now there's something that we can do. >> it gives you hope. >> mm-hmm, sure. >> yeah. unbelievably. i mean, we had none. >> reporter: since john is still in a trial, they're not paying for leqembi, but the list price is $26,500 a year. medicare plans to provide coverage as long as a doctor agrees to submit patient data. there are side effects. trials found a greater risk of brain swelling and brain bleeds for patients on leqembi leaving some doctors with concerns. >> the risk and benefits are quite disproportionate in favor of risk, and therefore, this is not a therapy that patients should really consider taking. >> it was go with a drug that might work or nothing. what would you do? they're traveling to london in

august. >> alzheimer's threw us for a loop, this drug has thrown us a lifeline. >> that was nbc's kate snow reporting. back with us now, dr. vin gupta. doctor, this drug's approval is encouraging news for people with alzheimer's and their families, but it isn't a cure, right? it just slows it down. so how much of a difference will people see? >> ana, that's the critical question. this is a milestone. this is a fist step towards new therapeutics to the point that kate made in her segment here. this is going to allow those with early stage alzheimer's to have an independent life for a longer period of time. is it a cure? no. we have to have clear understanding of what outcomes this is going to improve. when it comes to independent functioning, communication abilities, meaningful time with family, this is going to increase all those things that are important to patients. >> just for people who have the mild at least start of the disease. the drug's approval came with the fda's strongest safety warning called a box warning

because of potential side effects, brain bleeds, brain swelling. how comfortable should people feel taking this drug? >> let me emphasize here that almost 80% of individuals that were thought to have some degree of brain swelling, most of those cases resolved. those were identified on mris, not because of symptoms or some other diagnostic, and so, yes , there is a risk. these are serious potential consequences. they do occur in about 10% of patients. there are genetic tests that patients that might get one of these therapies should take. a certain gene might increase the risk of these side effects, but again, in most of these patients, asymptomatic even if an mri showed the presence, say, of brain swelling. something to keep in mind, something we're looking out for. >> dr. vin gupta, thank you very much for joining us. hope you have a wonderful weekend. up next on "ana cabrera reports" a houston teen believed to be missing for eight years was actually at his mother's

his mother the next day. nbc news correspondent priscilla thompson joins us now. i think a lot of people are saying, wait, what? this is just so bizarre, priscilla. break down what happened here. how did no one know where rudy was for nearly a decade? >> reporter: yeah, i'll start at the beginning. in march of 2015, rudy was 17 years old, his mother said he went out to walk their dogs and he never returned home. he effectively vanished. and for eight years police were investigating this as a missing persons case. there were volunteer groups that would go out and search for rudy and then fast-forward to last week, he was found unresponsive outside of a church. and this was hailed as a miracle that he was found after eight years of being missing, his mother released a statement saying -- thanking the public and the media for their support, saying he was recovering from his trauma. but then, neighbors began

speaking up saying, wait a minute, we have seen him in the neighborhood, he's been here the whole time and sure enough, when police spoke with rudy, they found that he had returned home the very next day, but they say that his mother never said a thing. i want to play some of what police had to say. >> the mother, janie, continued to deceive police by remaining adamant that rudy was still missing. she alleged her nephew was the person friends and family were seeing coming and going. however we disputed that. >> reporter: and since all of this has come to light there have been concerns raised from other family members and advocates about possible abuse allegations. police say that they have not found that in their investigation, that there was any abuse, no kidnapping, anything like that. so for now, no answers about why this mother and son would have lied for all of these years. ana? >> so strange. priscilla thompson, thank you for that report. turning to the fallout after
