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.

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 o
