describing how she found the gun and drugs hunter biden's core will take you live outside the courthouse and 17 nations, including the us, urge israel and hamas to come to a ceasefire deal, and idf the strike hits a un run school in gaza that israel says was a hamas compound and it killed dozens of people and today amid global conflict and uncertainty, we remember de day the turning point in the second world war when allied forces landed in normandy, france, 80 years ago, we are following these major developing stories and many more all come coming in right here to cnn news central today are crucial witness for the prosecution in hunter biden's federal gun trial, takes the stand. >> hallie biden, the widow for beau biden. who day did hunter after beau's death, has been testifying about finding and disposing of the gun that's at the center of this case. she's also described how hunter introduced her to crack cocaine and how she was embarrassed and ashamed about that chapter of her life. but on cross-examination, hallie biden also told the jury she didn't wind it as she did not witness hunter doing drugs or on the time that he bought that weapon. cnn senior justice correspondent evan beta's is outside the federal courthouse in delaware for us. evan court just took a break for lunch what more have we learned from hallie biden's testimony well, bars we saw juror are some jurors who rarely take notes, taking very, very, a lot of notes during hallie biden's testimony. >> i mean, she is the prosecution's star witness. and as you pointed out she is the only witness so far and path possibly in this entire trial, who will be able to say she believed hunter biden was using drugs in the month of october of 2018, who bought the firearm on october 12 of 2018? that's when prosecutors say that new he was struggling with drug addiction and knew that he didn't have didn't qualify to be able to buy that and that's reason why he's on trial here today. she found a firearm on october 23rd, and what she testified is that she believed that he was using drugs around the 22nd or the 23rd? under cross-examination, as you pointed out, she did say that she didn't actually witness it, but she believed based on his on his on his behavior, that he was using drugs. now the importance of this is this the defense is trying to drive home the point that prosecution has him using drugs in september and in november but during this key period before he bought the firearm they don't have any proof that he actually was using drugs. and what they're trying to do is to drive a little bit of distance and perhaps a little bit of his frame of mind from that period to have the jury doubt whether he knew he was breaking the law when he bought this fire alarm. she was very embarrassed. she said about her draw her drug use and you could see that this is a very emotional part of this, of this trial, emotional part of this testimony. hunter biden was looking straight ahead, looking at her periods during her during her testimony, boys and evan before we heard from her, we heard from this gun store employee, who sold hunter biden the gun what did jurors hear from him well, the importance of this gun store employees for you as he was there when hunter biden was filling out the form, the atf form 4473, where he attested that he was not an addict, was not somebody who is addicted to drugs drugs and what what we what we had today was to defense tried to shake him a little bit off his story and he didn't really budge very much. what the defense is i'm trying to do is to is to try to get to some of the discrepancies in that handling of that atf form. we know we know that there is a second version of that form that exists that the judge ruled could not be shown in court. the jury does not know about it, and so he was trying to see if he could get that gun store employees 42 at least open the way for him to talk about it? the gun store employee did not really budge and we will see whether this is something that a hunter biden's team will be able to use in a possible appeal should he be convicted. >> bores evan perez live from outside the courthouse in wilmington, delaware. >> evan, thank you so much. let's discuss these developments with former federal prosecutor, renato mariotti. we're not thanks so much for being with us this afternoon. let's start in chronological order. this gun store owner, the defense, tried to focus on two things during the cross-examination. one of them was how quickly he wanted this sale processed. and then the second was some of the details in the actual form. the questionnaire that a hunter biden signed. what's the significance of those aspects of the cross-examination prosecution has to prove beyond a reasonable doubt that hunter biden knowingly and willfully made a false statement on that form, and essentially, what the defense is trying to do is essentially suggests he was hurried through that. >> this is not a considered decision on his part. he was just the acting checking a box because as you alluded to earlier, boris is his testimony is essentially or his story is gonna be as defense is that he he was on a rehab program is coming out of rehab programs. so we thought of himself as sober that period of time. so this was not considered and really tried to give the jury some of the context so they understand this was not a very well thought out decision on his part, and therefore, not willful so hallie biden is testimony about her own use of crack was a stunning moment. >> the prosecution obviously wants to highlight her saying that she found remnants of crack alongside big gun in a hunter's car. that offense actually wants to muddy the waters. they want to highlight her own drug use to argue that some of the cocaine remnants that were discovered by investigators may not have been hunters. who do you think has the strongest argument there? >> well, look, this is obviously there's an uphill battle for the defense on this point generally. >> but i think what the defense is trying to do here is partly to call into question our her testimony. >> i mean, the fact that she was on drugs also could potentially impact your perception? the events at that time but the defense, as we discussed, and i think you discussed a moment ago what evan is really focused on trying to say, look, maybe he was using drugs the month prior. maybe you as using drunk some a month afterwards, but this was his state of mind during that month. so i think it does it's an effective point. but really the jury's not going to be swayed unless they just feel bad for hunter and think that the prosecution is wrong-headed in some in some fashion, the prosecution is expected to wrap up their case today. do you think that they've proven beyond a reasonable doubt that hunter is guilty? >> i think they have a strong case. i mean, i think there's a lot of questions here about why this case is broad and so on. this is a very unusual case i do think there's very, very substantial appellate issues. the statutes been called into question, the constitutionality of it, and so on there's an i meant that there was already a deal but i think in terms of the jury verdict, the defense is an uphill battle here and they're really hoping to get a hung jury we're not on my reality. >> appreciate your perspective on the case. thanks so much. briana the white house is continuing to push for an end to the israel-hamas war. >> and american official says the united states and 60 teen other countries whose citizens were taken hostage by hamas on october 7 are set to release a joint statement today to try to get a hostage release and ceasefire deal over the line. the president outlined a proposal last week, he characterized it as an israeli proposal, but hamas now says the plan that it received differs from what biden presented and it falls short of their demands in the meantime, the crisis in gaza continues to deepen the un is now warning half of gaza's population is expected to face death and starvation by mid-july, cnn's jeremy diamond is following the latest developments live force from jerusalem. and jeremy, there's also been an airstrike in gaza that killed more than 40. what are the latest details on that? >> yeah, that's right, briana, it's been a very deadly week in central gaza as the israeli military has clearly been stepping up, its airstrikes in that area late last night overnight. actually, i should say in the early hours of this morning thank israeli airstrike hit a un school and unrwa school that was effectively converted into a makeshift shelter for thousands of displaced palestinian and the israeli military says that it was targeting 20 to 30 militants who they say, were onsite sheltering there and planning attacks against israeli troops in an israeli military spokesman, colonel peter learners saying that he was not aware of any civilian casualties. but the reality of images that we've seen of the bodies coming out of that strike and the records from a luxe martyrs hospital in that area indicate that a majority of the 40 people who were killed in this strike were indeed women and children, and nine women and 14 children with the youngest being just for years old. this is obviously not the first time that we have seen the israeli military strikes in this area causing civilian casualties, just a couple of weeks next ago, actually, the israeli military use the same types of munitions that it used in this strike. the gbu-39 small-diameter bomb fragments were found at the scene of this strike. those are the same munitions that they use in that deadly strike in rafah on another camp for displaced palestinians that killed 45 people. the united nations relief agency in gaza, the main agency in gaza saying that this area was sheltering 6,000 people and saying that targeting un premises or using them for military purposes is simply unacceptable and cannot become the new norm. >> all right. jeremy diamond live for us in jerusalem. thank you for the very latest there today the world commemorates the historic invasion by us and allied troops that helped end the worst war in human history. this is the 80th anniversary of d-day. and on june 6, 1944, tens of thousands of troops from countries, including the us, the uk, and canada made an in fib landing on five stretches of the french coastline at normandy. operation overlord, as it was called, was a coordinated effort across air, land, and sea that the department of defense called the successful beginning of the end of hitler's tyrannical regime. president biden was there at normandy today we're not far off from the time the last living voices. >> those who fought and bled id de, will no longer be with us so we have a special obligation we cannot love what happened here, be lost to the silent, to the years to come. we must remember it must honor it and live it and we must remember the fact that they were heroes here that day does not absolve us from what we have to do today. democracy has never guaranteed every generation must preserve it. defended and fight for it among those back in france to mark the day us army air force corporal harold terrence on this day, 80 years ago, terrence was working as a radio operator mechanic based in northern england. >> he communicated with 60 p450, thunderbolt pi fighter planes flying flying over france in nearly two weeks later, terrence traveled to normandy to help transport newly captured germans and freed american pows to england. he reflected on this days, 80 years ago, and he had a message for world leaders as tensions are rising around the globe my company, we lost 30 fighter planes that they eventually before normandy was over. >> we lost every plane all 60 planes. and pilots were destroyed, shut down or crash it was a very sad time of all of her life they were all my friends, presidents, and prime minister zillow work that sit down and iron now that difficulties and the differences and remember that the pen is mightier than the sword and joining us now is former defense secretary under president obama, leon panetta interesting words. >> i think two here on this day, i just wonder, on this day what the data remember, especially as we are seeing the last surviving d-day veterans, and it's such a critical moment in the world. how are you reflecting secretary, on this day well, i think it's important for all of us to pause to remember what happened 80 years ago because united states were a leadership working with our allies came together in a massive landing at normandy and there are there were those who were willing to to fight and die for our country and to secure our freedoms and as we live in a dangerous world today, i think it's very important to remember the importance of united states were a leadership but also the importance of our alliances and the need to work together to make sure we protect democracy 80 years after normandy i think that's such a key part of what today means this was really the beginning of america as a superpower. this was the beginning of a world order that americans have so benefited from for the last eight decades. it seems like a lot of people have forgotten that. >> how do you drive that message home? >> and get them to recognize? you know, where this comes from. this sort of as much as some people will complain about how things are. there are a lot of wonderful things out there for americans. how do you get them to recognize that? >> i think it's important for our leaders to continue to remind the american people about the sacrifices that were made i know that we have a tendency to forget what happened in the past. and only you think about the present but the reality is that there is an important legacy here. the legacy stretches from franklin roosevelt to joe biden almost every president has committed this country trying to protect our freedom. so i mean, i think, i think it's important to remember that ronald reagan spoke at the 40th anniversary of de d-day and at that time he talked about learning the lessons of war, and not forgetting the lessons of war understanding that we can't be isolationists, that we have to work with our allies any ended that speech by saying, your hopes are our hopes and your destiny is our destiny that's a republican president i think we have to remind ourselves that it is important not to forget what happened at normandy because we need that strength. we need that courage today as we confront the adversaries of the present and speaking of that, we saw ukrainian president zelenskyy he was there today. he got a lot of attention for good reason. many people see parallels in the ukraine war to the conflict that was fought in world war ii. how do you see that parallel? >> well, i don't think there's any question. i mean, i i frankly i was a young boy and world war ii, i think it was about 6-years-old when normandy happened but i never thought that i would see in my lifetime another tyrant trying to invade a sovereign democracy. for no other reason, but that he does not believe the people of that country have the right to decide how to govern themselves so putin's invasion of ukraine is very much a wake-up call that democracy is still under threat in this world. under threat from tyrants like putin and others and under threat if we are not willing to come together, to pull together a strong alliance of united states and other countries to defend democracy. that's, that's the main message today, is that we cannot allow tyrants to succeed we cannot allow democracy to be lost because we fail to stand up, work together, fight together, and make sure that democracy would be protected secretary panetta, it is great to have you on this momentous day. thank you so much for taking time to be with us good to be with you and to
