happening right now a rare face-to-face that could change the world order. president biden in china's xi jinping meeting in california. biden saying he wants to get the two world powers back on, quote, a course. >> israeli troops raid gaza's largest hospital after accusing hamas of operating in the tunnels beneath it. meantime, the conditions in the hospital are deteriorating fast. its director saying there are newborn babies that are in, quote, severe danger. and a controversial border bill would make it a state crime to cross into texas illegally. opponents are concerned latinos will be racially profiled. it's now heading to governor abbott's desk. we are following the major developing stories and more all coming in right here to "cnn news central." happening now, the leaders of the two largest economies are sitting face-to-face as the world faces some of the most turbulent issues in modern times. president biden now speaking with china's xi jinping in a historic estate south of san francisco, and their conversation is expected to last for hours. in a meeting that took months of preparation to set up, president biden offered words of welcome to xi, just moments ago. both men acknowledging how critical cooperation is between the two global powers. >> we also have a responsibility to our people and the world to work together when we see it in our interest to do so. and a critical global challenge faced from climate change to counter narcotics to artificial intelligence demand our joint efforts. i look forward to beginning this discussion, and i welcome you. >> all right. let's go now to mj lee in california traveling along with this critical trip. mj, give us more details about this highly anticipated meeting. >> reporter: what was pretty remarkable there as the two leaders sat down to head into their series of bilateral meetings was hearing the two leaders really speak in agreement, at least in concept, about this notion of the two countries needing to avoid unnecessary conflict. you heard the president's comments there. he also said he doesn't want misconceptions or miscommunication. and president xi very much echoing that sentiment. he said, conflict and confrontation between the two countries has unbearable consequences. this is more of what president xi had to say. >> translator: one country's success is an opportunity for the other. it is an objective fact that china and the united states are different in history, culture, social system, and development path. however, as long as they respect each other, co-exist in peace and pursue cooperation, they will be fully capable of rising above differences and find the right way for the two major countries to get along with each other. i firmly believe in a promising future of the bilateral relationship. >> reporter: and we heard president biden saying that he believes there's no substitute for a face-to-face meeting of this kind. and, as you said, this meeting that we are seeing takes place the culmination of months of behind-the-scenes efforts by u.s. officials really to try to convince their chinese counterparts on the need for something to change. and what we were told in the days leading up to the summit is u.s. officials got a good amount of reluctance from their chinese counterparts on some aspects of what they were trying to convince them on, including on the issue of re-establishing that military-to-military communication. but we were interestingly told that in the big picture, they did sort of start to sense a growing recognition from beijing that something did need to change in terms of the u.s./china relations. now we'll see coming out of this meeting later today whether there are specific deliverables that come out of the summit. of course u.s. officials have very much been managing the expectations. but one key question that a senior u.s. official raised this week was whether china's engagement and this summit this week represents sort of their short-term view, or whether we are seeing beijing's interests in there being a permanent and long-term change to u.s./china relations. >> very, very important. we'll be waiting to see. so important to find out. mj lee live for us from california, thank you. pamela? we are tracking a day-long raid at the biggest hospital in gaza. israel says the controversial military operation in al shifa has provided them with, quote, concrete evidence that hamas was using the hospital as a command center. as images of damage and panic inside the hospital emerge, the israel defense forces have begun friending their case in the face of harsh condemnation from the u.n., the world health organization, and medical officials in gaza. earlier today hamas said the hospital complex is now fully in israel's hands. the w.h.o. said it has lost contact with the facility. let's bring in cnn's nada bashir in jerusalem. any more details about the evidence the idf claims it has? >> reporter: the idf has long held they believe hamas command and control center was positioned in the basement of the al shifa hospital following that overnight raid, israeli defense officials have released further details around the evidence they believe they have uncovered at the al shifa hospital. they say they found evidence of weapons, of military equipment, as well as technical assets which they have attributed to hamas and, of course, it is important to underscore that cnn has been unable to independently verify these claims. hamas and doctors on the ground at al shifa have long rejected the presence at the al shifa hospital. as we know, of course, there is a huge amount of concern over the safety and security of patients inside the hospital as this raid takes place. as we know, of course, the israeli defense force has said it is focused on uncovering hamas positions. it is focused on prioritizing the safety of civilians. as we have seen the last few days, particularly today amid that ongoing raid, we have seen israeli bombardment edging closer to the premises of the al shifa hospital complex. one doctor speaking to cnn overnight describing the shelling as closer and closer to the hospital shaking the walls of the hospital complex. you could hear the gunfire in his voice recording as well, so there is a huge amount of concern. you mentioned the condemnation from the united nations. we've heard from the u.n. human rights coordinator describing the military raid as appalling, saying that hospitals should not be turned into battlegrounds and calling on both sides to prioritize the safety and security of patients and civilians as well as medical staff inside the hospital. as we know, there are some 1,500 patients and medical staff in the hospital right now believed to be, according to officials, on the ground as well as hundreds of other civilians taking shelter on the hospital complex. there have been calls for civilians to evacuate. the warning we're hearing from doctors, hospital officials, it is near impossible to evacuate patients and civilians in the current conditions, with the current bombardment around the al shifa complex it simply isn't secure enough for civilians. doctors from doctors without borders, have described sniper fire being experienced as people try to move from building to building on the large al shifa complex. many require specialist care and the humanitarian situation. in order to evacuate many of the patients they have no safe guarantees for that evacuation. pamela? >> nada bashir, thank you. where do you think they stand on that front of edging closer to a deal? >> reporter: we haven't heard any clear movement to the news of hostages being released alive even though president biden did express some optimism yesterday that a deal would be done but exactly what that deal would look like isn't entirely clear for what is, we have learned from various sources here in israel and the u.s. as well, the broad parameters could involve the exchange of a large number of hostages being held by hamas. not all of them but a large number in exchange for a days' long ceasefire. but the specific details simply haven't been revealed. all of this is unfolding as the families of these hostages continue to try to mount pressure from around the world to get the focus back on these hostages, to get them released safely. there is a long march from tel aviv to jerusalem that is currently taking place with the families of hostage members, so a great deal of concern there. we learned, to add more details, how simply distressing this is for so many of these families. in a letter that the first lady of israel, sarah netanyahu, wrote to jill biden. in that letter it included the details israel has learned of a hostage that has given birth to a baby while in custody there in gaza. so clearly the urgency of this moment is not lost on the hundreds of family members who are desperately waiting for news as to how all of this will unfold, but the negotiations are moving painstakingly slow, and it's not exactly clear given the military operation that is are unfolding inside of gaza how this will play out in the days ahead. pamela? >> ed, thank you. for more on the humanitarian crisis unfolding, we are joined by the executive director of the u.n. relief and works agency in the u.s. thanks for coming on. there has been so much talk about the state of hospitals in gaza. obviously there was this raid there at the hospital that started yesterday, so it's a day long raid. can you tell us about the conditions there, what the patients and medical staff, how they're doing? as we heard nada bashir say, there are about 1,500 patients and medical staff at that hospital. >> yes. the conditions in gaza generally and across the strip, particularly at this hospital, shifa, are deplorable conditions. and i have heard some of the folks who have interviewed talk about the conditions. what i would like to add is communication is cut off, so, truthfully, we don't know what's going on inside the hospital except through the lens of the israeli soldiers there. that communication cutoff has both been probably because communication is cut off by the soldiers entering, but also there's a lack of fuel. al shifa hospital has been running on fuel-powered generators because the electricity has been cut off in the siege and we know in the last 24 hours very little communication has gotten through. yes, there are patients, hundreds of patients, doctors, and many people who sought shelter there ahead of the raid. and we know that, as was indicated, again, by those you've interviewed, sniper shots at those who have been trying to leave or go between buildings. this is not just over the last 24 hours. this is over the last couple of days. and there are so many bodies to bury, that they can't safely take away from the hospital, so they've been forced to bury the bodies in the hospital compound, which we all know is an incredibly -- is very unsafe for the spread of disease. this is deplorable conditions we cannot even imagine here sitting in our homes. >> you mentioned the fuel. earlier today a truck was able to deliver fuel from egypt but its use has been restricted by israeli authorities because of fears that the fuel would be used by hamas. what can you tell us about the delivery of humanitarian aid in the region? >> yes, so that fuel is very limited. we know we need 160,000 liters of fuel to power the plants that now have either stopped running or will be stopped running very soon, and to power hospitals and to power bakeries, to let bakeries bake bread. we are at a catastrophic situation in terms of fuel. the only fuel that's let in that unrwa has access to is those for humanitarian aid. the aid coming in is approximately an average of 35 trucks a day, is a drop of aid in an ocean of need. there were, previous to this conflict, 500 trucks going into gaza with needed goods and humanitarian food, medicine and other supplies. approximately 35 trucks a day is not enough to serve the need. something really spoke to me in your previous interview, somebody said with concern, which i would agree with, one of the hostages has given birth or is giving birthright now, and it is horrific to think about. i want to add it's horrific to think about 50,000 pregnant women in the gaza strip right now. 180 on average are giving birth a day under conditions which, again, are catastrophic and in which water is running out by today, tomorrow, there will be a lack of water for 270,000 internally displaced humans in gaza. >> i can't imagine. as a pregnant woman myself, i just can't imagine the conditions for these women who are giving birth there. and speaking of the babies that are being born, there is a big concern about especially transporting, some of the premature babies, incubators, respirators getting in, being delivered by israel. can you give us an update on that, whether those resources have been delivered to help these babies? >> yeah, i don't know. i don't know if any of those instruments are able to get in or not. god, i hope they can. i do know that without electricity, we can't -- incubators cannot be run. we've seen images of babies at al shifa hospital out of incubators with aluminum foil and other sort of temporary means to protect them. it is just unfathomable to think of what folks are going through right now, what civilians are facing, and i worry very much. al shifa is one of the oldest and largest hospitals in gaza and one of the few functioning hospitals after electricity has been cut and fuel has run out. people have nowhere left to go. if they tried to get out of that hospital, they're getting out in unsafe conditions. 102 of my colleagues at unrwa have been killed. 70% below the line in the south, over 50 installations have been hit, have been damaged. there is no safe place in gaza right now. and hitting any u.n. installation is a violation of international humanitarian law. unrwa's guest house in the south of gaza was hit directly the day before yesterday. international law is not being upheld right now. >> mara, thank you for coming on. >> thank you. still to come this hour, more warning signs for president biden's re-election campaign. he may be losing support among young voters. and closing arguments in the trial of a man who is charged with attackiki ing g pelosi wit hammmmer. in the race for 2024, president biden is facing an uphill battle with a block of voters critical to putting him in the white house. we're talking about young voters. in georgia, jeff zeleny asked why some of them are less inclined to support biden this time. people may not vote because they say, well, this happened under the biden/harris administration. >> reporter: as kerry singleton looks ahead to the next presidential election, he's thinking back to the promises he heard president biden and vice president harris deliver on a visit to atlanta. >> pass the freedom to vote act. pass it now! >> reporter: on that winter day, the president was closing in on his first year in office. hopes were high for singleton and other students on the grounds of clark-atlanta university and morehouse college. since then voting rights legislation stalled. the supreme court rejected a student loan forgiveness plan and high prices from food to housing are fueling economic anxieties. >> i do think that everyone is willing to hold the administration accountable for some of those promises that were made, and if they don't happen, i think it will be a scary election. >> reporter: for all the warning signs facing the president a year before the election, the skepticism and apathy of young voters ranks high. >> folks just feel poorer right now than two years ago. there's going to have to be a lot of conversations about how we feel like our issues are being heard. >> reporter: the youngest woman to win a seat in the georgia senate. in 2020 she went door-to-door in the atlanta suburbs, building a coalition to help biden turn the state blue. that coalition, she said, could fracture by the president's handling of the israel/hamas war. >> i think that young voters recognize you can't bomb your way to peace and security. and so we do feel uncomfortable with that. >> reporter: rachel carroll's first vote went to biden. she said she doesn't regret it given the alternative but is disappointed by some priorities of the white house. >> if they can fund the war, they can find a way to pay off our student loans. >> reporter: young voters were a critical component of the president's victory particularly here in georgia where biden defeated donald trump by only 11,779 votes out of nearly 5 million cast. exit polls in 2020 show voters 18 to 29 made up 20% of the georgia electorate. the only state of the top six battlegrounds where the percentage of young voters exceeded the national share of 17%. biden won young georgia voters by 13 points, according to exit polls. but now, a year before the 2024 ele election, voters under the age of 30 here in georgia split 46% for trump and 44% for biden. according to a "new york times"/sienna college poll. >> the excitement is not as high as it was last time. >> reporter: gibson and some classmates wish they had more inspirational and generational choices. >> we have to pick between two different people who have very, very old and up in age. >> we would like to see biden pass the baton. >> reporter: the vice president, whose college tour brought her back on campus this fall, resonates more. >> i think she sparks that energy. when she came to morehouse it was fun. >> reporter: with biden at the top of the tech, potentially facing a rematch of the 2020 race, voters say the burden rests on him to deliver on his promises and not take their support for granted. >> just as well as we hold trump accountable, we have to hold biden accountable. >> reporter: and some of the biggest achievements of the biden administration, the infrastructure law, the inflation reduction act, even lowering prescription drugs simply do not resonate as loudly with the younger voters we talked to, brianna. there's no doubt the biden campaign realizes it has its work cut out for them. they said it's a deeply consequential election for young americans, and they will show that contrast between what they call the maga agenda and president biden. again, if trump becomes the republican nominee, they look forward to that contrast. but some voters we spoke to look forward to seeing more and hearing more from president biden. brianna? >> jeff zeleny, thanks for that report. a hearing just ended in atlanta that sought to seal in evidence a case where donald trump would not be able to pardon himself. fulton county, georgia, d.a. fani willis has accused the former president and 19 others of racketeering and 2020 election interference. there is a reaction of the leak showing defendants who cut deals speak to go investigators, and they were part of a plea deal for attorneys jim ellis, sidney powell, ken chesebro. nick, the hearing just ended. what happened? >> reporter: prosecutors and defense attorneys have agreed in principle to a protective order where prosecutors will have to designate what they believe is sensitive materials in the pretrial discovery material and defense attorneys will have 14 days to respond. i should mention the judge here, judge mcafee, hasn't yet made a ruling from the bench and today was no different. listen to him talk about what a protective order could look like in this case. >> the state originally proposed what i would characterize as a blanket, umbrella protective order, anything and everything that is turned over that wasn't already public or part of the defense file was going to be held under seal. whereas my reading of mr. schaefer's proposed order is there is going to be this intermediary designation of some things will be sensitive and that's what's not allowed to be turned over, so it's not everything. is
