it's going to be back with you in this second hour of "chris jansing reports." at this hour, searching for safety, civilians in southern gaza are now being told to flea as the israeli military ups its ground offensive against hamas. for those trying to get out, the big question is go where? the white house is under increasing political and diplomatic pressure over the issue. we do expect to hear from

national security advisory jake sullivan at any moment from the white house. and the terror investigation underway after a deadly attack with a knife and a hammer near the eiffel tower. what police are saying about the islamic radical that is under arrest. >> and here at home, is it real or revenge? the move by republicans that the white house says will be throwing red meat to the right flank of the house. plus, the vote happening right now over the deal reached between actors and studios after that historic strike. the talk behind the scenes, and why some expect this vote could be a close one. our nbc news reporters are following all of the latest developments. we start with the latest inside gaza. nbc's david noriega is in tel aviv for us. david, the israeli military says the main road in gaza that's being used as a humanitarian corridor for those evacuating now constitutes a battlefield. what more are you hearing on the ground?

>> reporter: chris, the biggest development from the last 24 or 48 hours or so is the fact that the idf is now currently present on the ground throughout the gaza strip, including in the south. we're getting reports of heavy air strikes in the south. much of the idf's activity appears to be focused on the city of khan younis. we have seen videos of civilians, including very small children being treated in hospitals, which health officials from the world health organization say are badly overwhelmed. as far as the evacuations go, chris, israeli authorities say these evacuations are one of the precautions they take in order to mitigate civilian casualties. they are giving precise instructions on shelters and other specific locations they can go to where they will be safe. what we are hearing from gazans on the ground, is they feel there's nowhere to go. 80% of the gaza strip has been displaced in this war. i want to play you a short clip of a video of a group of palestinian journalists inside the city khan younis who

gathered to play a video and a song. i'll tell you what the song is in a bit. take a look. >> [ singing in global language ] >> reporter: chris, that song is called "we will stay here," and what it speaks to is a widespread fear among many palestinians in gaza, but also in the west bank, that these repeated evacuations, these repeated displacements will lead to the mass displacement out of the gaza strip across that southern border into egypt. this is something palestinians are afraid of, that they reject, the egyptian government rejects this possibility, and i should say the u.s., including vice president kamala harris has said that it is strenuously opposed

to mass displacement over the border. the government has not said that's the intention but the fear is widespread. you hear palestinians in the gaza strip and in other parts of the palestinian occupied territories discuss all the time. it's something that comes up very frequently. chris. >> david noriega, thank you. now to the terror investigation that's underway in paris. authorities say a french citizen who swore allegiance to isis stabbed and killed a tourist and injured two others with a hammer near the eiffel tower. nbc's josh lederman is following that story for us. french police say this man was already on their watch list. what's the latest? >> reporter: well, chris, right now paris and frankly, western europe are reckoning with how yet another terror attack was carried out without being stopped in advance. because the list of red flags here was very long. you mentioned he was on a watch list. he was put on that terror watch list after he was previously imprisoned for four years for attempting a previous failed

terror attack, and authorities in france say that not only was he known to have severe psychiatric illness, but he had also been in contact with jihadis in france that plotted other terror attacks, and it's becoming more and more clear as police carry out this investigation that while he had a long and troubled history, that more recently he had been very agitated by the events in the israel-gaza war. this suspect is said to have shouted allahu akbar as he was carrying out the attack, and told police after he was tasered and apprehended that he was upset about the treatment of muslims in afghanistan and other parts of the world. calling france an accomplice to israel's actions in the gaza strip, and so this is raising the level of concern about how the events in israel and the gaza strip are starting to spill into incidents of instability, and even violence in other parts of the world. with france already at its highest level of alert for

national security threats. that came after another deadly terror attack that killed a teacher in northern france in october, and of course this is a country that's about to host the olympic games in just about eight months. police say they are at a permanent state of vigilance, but they say they will keep the olympics safe, chris. >> josh lederman, thank you. here at home, a vote to authorize an impeachment inquiry into president biden. nbc's ali vitali is reporting on capitol hill. what are you hearing from lawmakers about all of this? >> this was an open question about whether or not republicans had the votes to open an impeachment inquiry. that's still a question that we have, but republican leadership seems to be under the impression that since lawmakers have gone home for thanksgiving, huddled with their constituents, now is the time to move on this, and public opinion, they say, is shifting in their favor. here's more of what the newly minted speaker had to say, and why he's shifting off what his predecessor did, bless the

effort but not hold a vote on it. >> has become a necessary step. alise and i served on the impeachment defense team of donald trump twice when the democrats used it for brazen partisan political purposes. we decried that use of it. this is different. we are the rule of law team, we have to do it very methodically. >> reporter: the reality of course, chris, as we have been covering the entirety of this congress is republicans have been undergoing their investigations of hunter biden, of biden's brother already without the impeachment inquiry banner officially stamped over this. nevertheless, they say they want more power to be able to subpoena things like bank records and even just today, the head of the oversight committee, james comer teasing out what he says is further evidence of payments between president biden and his son hunter, but, again, i think it's really important to underscore that none of these things that the committees say they have found are actually proven to be nefarious at this point, and at this juncture, it looks like the impeachment

inquiry is a solution in search of a problem. >> ali vitali, thank you for that. let's go to hollywood, being voted on as we speak. chloe melas is following this story. voting is set to end tomorrow, but there is growing criticism over parts of the deal. is there question about the outcome here? >> reporter: over 160,000 actors have been voting on this deal that sag has called ground breaking over the last few weeks. and like you said, that vote will end tomorrow, they will tabulate the votes, and nbc news is learning that although the deal will likely pass, potentially by very slim margins. i had one actor who said he hoped for stringent ai protections. let's not forget, though, sag calling this the billion dollar deal with the highest increase in 40 years. they have addressed issues over

artificial intelligence. the chief negotiator, duncan crabtree and i were speaking over the phone, and they said to me,'m going to read you what he said, is it perfect? no but it is ground breakg. he goes on to say, it's a deal that achieves what our members need us to achieve. more than the last three negotiations combined, and something to build upon with ai adding we will be back at it in two and a half years. i also spoke to sag's executive president telling me she'll be happy if this even passes with 51%, this is the deal their members need, and they need it now. now, if potentially, this does not pass, i've had individuals tell nbc news that likely the union would not go on strike, they would return to the negotiating table and work that out with the studios and streamers. this is something that has put hollywood on hold for months and many out of jobs, and i know that there are everyone is

watching to see what the outcome will be tomorrow, chris. >> and today, before the supreme court, should the family who made billions of dollars off opioids be immune from future lawsuits over the crisis. some families who lost loved ones want the court to say yes. how are the justices leaning? we'll have that in 60 seconds. it's ripe in here. my eyes are watering. i'm a busy man. look how crusty this is. shameful. ugh, it's just too much. not with this. tide. tide can tackle any pile. that a tackle pun? just clean the pile, ron. okay. this too. that was easy. when stains and odors pile up, it's got to be tide.

protests today at the supreme court, while hearing arguments in controversial opioids case. the question at hand is it fair for the family at the center of the drug epidemic to be immune from ever being sued in civil court if they pay a large lump sum. the biden administration is challenging that $6 billion settlement reached by states, drug manufacturer purdue pharma and the billionaires who founded it, the sackler family. while many victimized families back that settlement, others who lost loved ones are protesting.

they argue it's not a fair deal. >> they need to pay for what they did and what they have offered in that paltry $6 billion settlement will help some people, but it is not the justice that needs to be served in this case. there is nothing, nothing that can justify the loss of human life that they have caused. hundreds of thousands of people are dead because of their greed. >> nbc's lawrence hurley who covers the supreme court joins us from d.c., and i'm also joined by joyce vance, former u.s. attorney and law professor at the university of alabama. welcome to you both. lauren, what were the main take aways from today's arguments? >> it seemed like a difficult one from the justices. on the one hand, there's a dry legal question about whether bankruptcy judges have the power to sign off on this deal that would allow the sackler's off the hook for future claims. on the other hand, it came up in

the argument, just as concerned about the practical impact, which is if they allow the settlement to go down, or they potentially blow up the settlement, is another one going to be negotiated? is that possible that that can still move forward at all, and then lurking in the background is this idea of if they don't accept this $6 billion offer from the sacklers, would anyone actually be able to sue the sackler family, many of whom live overseas, and actually get ahold of that money, and that's really open to question? >> before these arguments happened, there are good arguments on both sides, and in fact, families impacted by the opioid epidemic are divided on this settlement. what jumped out to you today? >> right. so i think lawrence's assessment is dead on the money, chris. this is an usual case for the justices. the law is straightforward when it comes to bankruptcy. if you want to have all of your debts discharged, if you want to be free of the risk of future

lawsuits, then you have to put all of your resources, all of your financial resources on the table to be distributed in the course of that bankruptcy. and justice kagan pointed this out in her questioning saying that is not what the sacklers' did. if they follow the law, the supreme court may blow up the settlement. there is a certain pag matism. much of the money is earmarked, along with some of the family members, a pragmatic approach might dictate in favor of letting the settlement go forward. it will be very interesting to see what the final vote is. not a lot of clues from the justices. today in oral argument, they all seemed to be testing out this central dilemma. >> when the settlement was announced, you know this, it looks like this could essentially end thousands of these cases. what are the implications, not just for the parties here, but

potentially any organization that turns to bankruptcy protections to resolve a mass injury case. >> right. that's the risk here. i mean, not to put too fine of a point on t but the sacklers are in this position of trying to buy their way out of future lawsuits because they were able to put a lot of money on the table here. that's in some ways how this case can be characterized. can you buy your way out of future liability by coming forward in bankruptcy in this way. the question is what happens in the next case and the case after that, and corporate liability, civil and perhaps criminal fines, manage to buy their way out with an early bankruptcy settlement. lots of different equities will need to be balanced here by the court. >> joyce vance, lawrence hurley, thank you both. as the associated press puts it, the earth is running a fever, what to do about climate

change at the center of an intense international summit in dubai. the planet becomes less healthy, so do we. the disturbing numbers, next. rst whatever we did here would be an emblem of what small communities can achieve. trying to give a better life to people that don't have the means to do it. si mi papá estuviera vivo, sé que él tuviera orgulloso también de vivir de esta viviendo una vida como la que estamos viviendo ahora. es electricidad aquí es salud.

here we go. can we land? you're old enough to do it in the sky now. but it's gross. there is no way we're landing. are you sure no one is watching? gwen mallard! do it now, or we leave without you. ok. let's go right to the white house press briefing. this is jake sullivan, the national security adviser. >> we're still talking about trying to find a way forward on hostages. we're talking about sustaining and expanding the humanitarian

assistance making it into gaza, and we're talking about of course the status of israel's military operation as it defends itself against a terrorist organization that has declared its intent to repeat the october 7th massacres again and again and again. and i briefed the president regularly throughout the weekend and regularly throughout the day today. on thursday, here at the white house and with some families joining virtually, i met with the families of americans who were still being held hostage by hamas. it was my second such meeting by myself. i also joined the president's meeting with the families and i can tell you, it has not gotten any easier. what these families are going through is gut wrenching, it's heart wrenching, and it's unimaginable, unthinkable for any of us. we continue to do everything in our power under the president's leadership and guidance with his direct involvement and participation to try to bring all of these americans home, as well as all of the hostages and

we will not rest until we have succeeded in doing so. the president and i, along with secretary blinken and director burns will stay in touch with our israeli and qatari counter barts and egyptian counter parts to press hamas on this issue. right now, hamas is refuse to go release civilian women who should have been part of the agreement, and it is that refusal by hamas that has caused the end of the hostage agreement, and therefore the end in the pause in hostilities. since october 7th, we have also worked very hard on the humanitarian assistance front. we have announced $100 million for the palestinian people including through other u.n. agencies, as well as other humanitarian actors, and we call on the international community again today to fulfill the u.n.'s flash appeal. we're working really on trying to overcome remaining obstacles to increasing and sustaining the flow of humanitarian assistance to innocent palestinians in gaza. secretary blinken made this a

major focus of his trip to the region this week, and we will continue to do everything we can directly from the united states to flow assistance into the region. last week, we had a successful air lift, u.s. air lift of 54,000 pounds of medical items and food aid to delivery to the civilians in gaza. that's the first for a number of planned deliveries that will take place over the course of the coming days. beyond what is happening immediately, there are developments in the region more broadly. this past weekend saw four attacks against three separate commercial vessels operating in international waters in the southern red sea. three vessels that are connected to 14 different nations, which goes to show you the extent to which this is truly a source of global concern, and a threat to international peace and stability. as d.o.d. has replayed, the burke class destroyer, uss carney responded to the distress

calls to the ships and provided assistance. in doing so, it detected three uavs at three different times heading in its direction. it took action against all three uavs. we cannot assess at this time where the kearny was a target, but it took prudent action in taking down those three uabs, and we will continue as we go forward to consult closely with allies and partners to determine and take all appropriate responses. we have every reason to believe that these attacks, while they were launched by the houthis in yemen were fully enabled by iran. on ukraine, as you've all seen earlier today omb director shalanda young sent a letter to congressional leaders, explaining that without congressional action, the administration will run out of resources by the end of the year to procure more weapons and equipment for ukraine, and to provide equipment from u.s.

military stocks without impacting our own military readiness. the resources congress has provided for ukraine and other national security needs have halted russia's advances in ukraine, helped ukraine achieve significant military victories, including taking back more than 50% of the territory that russia had previously occupied, and by revitalizing our own defense industrial base, jump starting and expanding production lines and supporting good paying jobs across the country. now, it's up to congress. congress has to decide whether to continue to support the fight for freedom in ukraine as part of the 50 nation coalition that president biden has built or whether congress will ignore the lessons we have learned from history and let putin prevail. it is that simple, that stark a choice, and we hope congress on a bipartisan basis will make the right choice. as director young said, we are running out of money, and we are

nearly out of time. congress has to act to take up the president's supplemental request, which advances our own national security and helps our democratic partner in ukraine fight against russian aggression. finally, as karine was describing and talking through the achievements we have made on methane, vice president harris traveled this weekend to dubai for cop28, and she delivered the united states's national statement and participated in a leader session on renewable energy. throughout her engagements, the vice president made sure we will keep delivering on the ambitious climate agenda in history at home and abroad. support adaptation, and boost climate resilience. as a result of president biden's leadership since he took office, the united states is once again leading the world in responding in an urgent and sustained basis to the climate crisis, and with

apologies for with the opening remarks, i would be happy to take your questions. >> i want to ask about the attacks on houthis over the weekend. the houthis have threatened to attack any commercial ship in the renal that has ties to israel. you mentioned they had ties to 14 different countries. did all of these ships have ties to israel. >> we do not believe all three ships had ties to israel. it goes to show you the level of recklessness, israeli owned or had some connection to the past, that doesn't make it a justifiable target under international law than if the ship didn't have ties to israel. some ships we believe may not have i don't want to give a definitive answer to that. in addition to that, the position of the united states consistent with the position of

the u.n. security council and consistent with the position of, what we are doing now is engaging in intensive consultations with partners and allies to determine the appropriate next steps. the last point is just to underscore something i said in my opening statement. we are talking about the houthis here, they are the ones with their finger on the trigger, but that gun, the weapons here are being supplied by iran, and iran, we believe, is the ultimate party responsible for this. >> reporter: and when you talk about next steps with partners, is one possibility setting up some kind of escort service? you talked about the uss carney that responded. is there a possibility the u.s. would partner with others in the region to escort this ship? >> we have maritime task forces elsewhere to deal with threats to shipping. it's true in the gulf, true off the coast of somalia, with

respect to piracy, and we are in talks with other countries about maritime tasks involving the ships from partner nations alongside the united states in ensuring safe passage of ships in the red sea. those talks are ongoing as we speak. i don't have anything formal to announce. that would be a natural part of the comprehensive response to what we're seeing here. >> we're going to continue to listen to jake sullivan, but a couple of key points he has touched on, the hostages that are still remaining as the fighting has resumed between israel and hamas. i want to bring in retired general steph twitty, and former deputy commander of u.s./european command. so you just heard jake sullivan reference the attacks on the vessels in the red sea, we don't know if this was an attempted attack on the uss carney, which did respond, but there have been insurgent attacks on the

proxies, and commercial forces around the world since the start of the war. what more it can be done to deter them at this point? >> well, i think a couple of things that can be done, you heard talk about perhaps a global escort mission, where we would bring our partners and allies in to assist in escorting commercial ships. 10% of the world commerce transit through the red sea, and so it is a vital shipping lane, and we must protect it. i think that would be prudent to bring our partners in to help the fifth fleet deal with this problem. that's one. the other one is to couldn't to be vigilant, and when we see the houthis, because we have the technology, we know when most of these ballistic missiles would fire off because we have ages

assure and on our ships, we continue to be vigilant and attack back to assure that ballistic missiles do not interfere with the shipping lanes, so i think that's something else we need to continue as well. >> you heard jake talking about meeting with the families. not surprisingly, this isn't getting easier. we know about the deteriorating conditions of the last groups of hostages released. the last number i saw from israel is that there still remain something close to 140 people who are being held by hamas. there are, according to the white house, unaccounted for, we don't know whether they're being held or by whom, seven men, one woman, four americans have been released. what do you see as the likelihood and the circumstances under which there could be another at least temporary truce, temporary cessation of fighting and more hostages being

freed? >> well, i think first you have to get hamas and israel obviously to agree to a cease fire, and to start negotiations back in terms of releasing the hostages. i don't see that happening anytime soon. hamas has said that they don't intend on releasing any hostages until after the end of the war, and israel has said that they're going to continue to attack and they're going to continue to attack south of the gaza strip. and as you can see, they're pretty much putting a powerful hammer on the southern part of the gaza strip as we speak. and so i don't see anytime soon, unfortunately, any negotiations resuming in terms of releasing those hostages. >> lieutenant general steph twitty, thank you so much. and still ahead, the severe toll that climate change is having on human health coming

the u.n. climate summit included a day focused on the devastating impact on human health. it couldn't come at a more

critical time. as the a.p. put it, earth is running a fever, over a brown haze over dubai, the cop28 summit moved past two days of rhetoric, and calls of unity to concerns about health issues like the deaths of at least 7 million people globally from air pollution each year. and the spread of diseases like cholera and malaria, as global warming upends weather systems, and tensions inside the event bubbled over today after the oil executive leading the talks initially claimed there was no science behind the idea of phasing out fossil fuels in order to keep global warming in check. then he kind of backtracked, later reiterating his commitment to climate science. matt gorman is a republican strategist who most recently served as senior communications adviser for campaign. and vin gupta, a policy expert and medical contributor.

a main focus of the summit is the contagious effect, how climate change happens and the results on human health. tell us what you found, what the medical community now knows, what's the science? >> well, chris, thank you for highlighting this, the trend lines here are concerning. we have been talking about this. heat is the biggest arguably risk factor for human health as we approach the middle of the century. we are expecting heat deaths in the united states, warming at a rate that's 60% higher than the re of the world, to increase by 400%, particularly those 65 age and older. air pollution, i'm a pulmonologist, this is the fifth leading risk factor independently, worldwide, that's a concerning trend line. epidemics and pandemics. vectors for infectious diseases can spread their disease for over greater periods of time in the year, greater altitudes, and food insecurity, the issues with

health and climate are why we're finally seeing a climate health day and health professionals mobilizing on the issue because it's the most effective way to talk about it. >> the less money you have, the more likely you are to feel this. let's do the most simple example we can give, which is if you're living in an area where temperatures are extraordinarily high, unusually high, and you can't afford air-conditioning, you don't have an air conditioner, you have an issue, whether it's you're ageing, whatever the health issue is. that's one example. for this reason, the biden administration has been putting a focus on what they consider to be marginalized communities. how important is that. >> it's critical, admiral levine, the assistant secretary for health issued a statement at cop today, focusing on the fact that this is a big area of focus administration, specifically health equity and climate and health. we know that air pollution, for example, disproportionately impacts underserved communities, those lower from a socioeconomic

standpoint. they have poor air to breathe. i will say the biden administration has focused on methane gas. we heard the national security adviser talk about. if you inhale methane from a gas stove, it increases your risk for asthma. there are a lot of solutions we can talk about. there's innovative solutions like putting hospitals on solar powered micro grids. in the sun belt, if there's a catastrophic failure of the electrical system, our hospitals and critical infrastructure are safe and care for people. lots of nuance for climate and health. we can talk about the risks all day, and the problems all day and the trend lines. solutions are key. >> dr. vin gupta, i know you have other places you need to be. it's great to have you here in person. thank you for that. matt, that brings me to you. president biden is not attending this summit. vice president harris did announce that $3 billion commitment to what's called the green climate fund. it supports climate action in developing countries.

tell us more about that, and i wonder if it can blunt some of the critics who say frankly biden should have been there. is it a problem not to have been, especially for younger voters? >> you talk about younger voters. that's something that's been a flash point for democrats of late. you have seen in your nbc poll, he has been having trouble, instability among younger voters when it comes to the conflict in israel and gaza, so this is an opportunity, i believe, in their mind to use this issue as a way to galvanize younger voters. talk about the stakes and what they view as what biden and harris have done. you're right, if you wanted to escalate, and make sure everyone in the country covered it, you send joe biden to stare down whomever you view as your antagonist. you get enough, but you're not getting the front pages of every newspaper the in country. >> and we have also seen, and this has been widely reported there, as we see that video of

vice president harris, companies made big cdges that they seem took balking on. the sate budget committee chair sheldon whis whitehouse wrote an e-mail, we have seen little evidence that the insurance industry is taking meaningful action to align its investment and underwriting decisions with the paris agreement. and that's just one example. so what about the balancing act between business and climate change policy? can the president push big business in an election year, and does he get a little help from the fact that polls show more and more americans belie in and are concerned about climate change? >> it's a couple of things. number one, what you have seen in recent years, especially in the last years ago are businesses retreating from more. they have seen the last couple of years, once you enter the political arena, you cannot exit

it. so i think when you saw a couple of years ago, these businesses making these bolder proclamations, these big public pronouncements, once they get involved, they see what's at stake, and they try and shy away. and so i think on that dynamic, that's something they're seeing, but again, when you come at this from a business end, i mean, i was just in iowa quite a bit. i think what you see is a lot of people in the midwest, independents, certainly republicans, too, people you need to get this done. they shy away at government mandates. they want to do this through solutions they're incentivized to do did. banning things or requiring things that might raise their prices, they balk at quickly. >> matt gorman, stay with me. we have more to talk about. in the meantime, governor ron desantis is hitting the trail hard today and taking new shots at donald trump. the strategy behind his latest campaign message, and why it could potentially backfire. that's next. could potentially backfire that's next. trading to help sharpen your skills, you can stay on top of the market from wherever you are.

. republican presidential candidate ron desantis is on the attack, bashing former president donald trump and claiming he's running on things that he didn't do as president including repealing and replacing obamacare. but meanwhile, with just two days until the final gop primary debate, the chaos continues inside desantis's super pac, naming its third ceo in two weeks. republican strategist matt

gorman is back. also with me, dasha burns with the latest reporting from inside camp desantis. what is going on with the super pac? >> okay. this latest ceo debacle is just one incident in a string of incidents that have just caused a ton of turmoil between the super pac, the campaign, and now remember there's a new super pac. and that is all part of this here. so you've got a third ceo that's in place now with the backdrop of this tension that has been building. and just a couple of weeks ago, chris, the tension built so high that nbc news, me and my colleagues, john allen and matt dixon reported on a near board room brawl that almost broke out. that is the level of chaos that we've got here because the governor for some time now has been frustrated with never back down, feeling like the super pack isn't doing exactly what he wanted. remember, they can't legally coordinate. the super pac has taken on this out sized role that is not

historically normal between a campaign and a super pac. initially, they thought it was genius. now that's causing these problems, and now they have started a new super pac, which they think might potentially help solve all of that. that's a mess. in the meantime, he's on the campaign trail in new hampshire now, delivering a message where he's taking on donald trump head on, took him a long time to get to that place. here's the message that he thinks is the winning one against former president trump. take a listen. >> trump is promising to deport illegal aliens. you know, he made the same promise in 2016. he deported less than obama did, obama's first term. that's true. it's sad that that's true, but that's true. talking about building the wall, talking about draining the swamp, talking about doing all the things that i cheered for at those rallies in 2016. so the question is, if he didn't do it the first four, how all of a sudden is he going to be able to do it, you know, the next

four. >> chris, it took him a long time to get to the point where he would talk about trump directly, when he was talking to voters like that. the question is it too little, too late. for all of these candidates, by the way, to take on trump, what, six weeks ahead of the iowa caucuses? >> and six months after you announced you were running for president, so yeah. so, matt, let me go to where this campaign is right now because you have a candidate who was considered the real challenger, six months ago. potentially, to donald trump. who's what, 40 points behind nationally? you clearly have a situation where the money situation is in chaos. so does one naturally follow the other, if you're going to be 40 points behind after people have pumped this money and attention into it, things are going to blow up? >> well, i guess a couple of different things, right, i worked for jeb bush in 2016.

the super pick cannot substitute for an actual campaign. think of it this way, we're talking about football. it's the kicker of the football team, the quarterback, the super pac cannot be the quarterback of the team. that's what the actual campaign is for. if you have a bad quarterback, you're not going to be doing well. think of it like that. and i think also too, do no harm. we spent half of the last segment talking about the drama and the process surrounding staffing of a super pac. as we're six weeks out from iowa, that doesn't help you get your message out to voters. if ron wants to talk a valid argument about what trump did or did not do in the second term, there has to be consistency and steadiness on the outside group side. he needs it with only six weeks to go. >> matt gorman, dasha burns, to be continued. thank you very much. there's a new investigation into air traffic controllers, boy is it raising major safety

concerns. we've got those alarming findings next. we've got those alarming findings next. and out of the hospital. don't take entresto if pregnant; it can cause harm or death to an unborn baby. don't take entresto with an ace inhibitor or aliskiren, or if you've had angioedema with an ace or arb. the most serious side effects are angioedema, low blood pressure, kidney problems, or high blood potassium. ask your doctor about entresto for heart failure.

a dire shortage of air traffic controllers have creating an increasingly dangerous situation in the skies. internal faa doctors based on controllers' anonymous reporting details mistakes made by overworked and exhausted staff. some of those controllers claiming that they're colleagues use drugs and alcohol on the

job, even fell asleep. nbc's tom costello covers aviation for us. what have you got for us, tom? >> reporter: controllers are facing mandatory overtime, ten hour days, six days a week as we are facing record numbers of passengers in the air right now. there's a self-reporting mechanism controllers have to report when they may have made a mistake or there was a close call, and now some controllers are taking to that site to report drug and alcohol abuse, even sleeping on the job. it's a high stakes, high pressure job, and 2023 has been a year of close calls, involving both pilot and controller error, including this one in austin when a controller cleared a fedex plane to land just as a southwest plane was departing. >> southwest abort. fedex is on the go. >> reporter: one big problem, controller fatigue. 77% of air traffic control facilities are under staffed.

leading to mandatory overtime. medical issues forced neil burke to retire this year. >> we're tired of working six days a week, we're tired of working ten-hour days. >> reporter: nbc news has obtained internal faa documents, reported by "the new york times," details controllers' anonymous reporting of mistakes and exhaustion. among the entries, many employees can be observed sleeping on the job. if i had not been fatigued, i may have been able to recognize the aircraft lined up for the incorrect runway sooner, and i pray no one dies due to controller fatigue. also included, isolated cases of controllers using alcohol and illegal drugs while on position. one claimed a colleague regularly smoked marijuana on break. another said a controller bragged about making big money buzzed. with more than 10,000 certified controllers on the job, the faa chief says substance abuse is

very rare. >> we monitor for drug and alcohol use. we have robust reporting, and follow up on every lead that comes in. >> reporter: both the faa and controllers unions say overtime fatigue is real. >> you're missing your home life. you're missing your kid's ball games and your spouse's events, and it does have an effect. >> reporter: controller michelle hagger left last june. >> that is not a sustainable lifestyle to be working that hard at a job that required so much mental focus at all times. >> we're working every day to make sure the system stays safe. it has been for decades. we're not letting down our guard, and we're working that issue hard every day. >> reporter: despite the fact gnat faa hired 1,400 controllers this year, because of so many retirees at the end of the year, there's only a net gain of eight. the problem is they are well behind on training. this goes all the way back to before the pandemic. the pandemic shut down the academy, and they're now down 1,500 to 3,000 controllers.

it will take years to catch up, which means many more months and maybe years of overtime. back to you. >> unbelievable stuff. tom costello, thank you as always. >> and that's going to do it for us this hour. tonight, former congresswoman liz cheney joins rachel maddow to talk about the state of the republican party and her warning about donald trump getting back into the white house. that's tonight, 9:00 p.m. eastern right here on msnbc. and make sure to join us for "chris jansing reports" every weekday from 1:00 to 3:00 p.m. eastern here on msnbc. our coverage continues with "katy tur reports" right now. good to be with you. i'm katy tur. the white house says it will not get sucked into the israel-hamas war, but escalating confrontations outside of israel could draw the u.s. in. the pentagon says a u.s. navy destroyer shot down three drones over the red sea
