this morning, another masshooting in america. this time, in philadelphia. police say at least five people were killed by a man armed with two weapons and a bulletproof vest. we'll go live to the scene and speak with the congressman who represents pennsylvania. >> also developing news from

overseas, as israel launches strikes against palestinian militants in the west bank. what the white house is saying about the stepped up violence there. and later, new reporting on the race for president. why the first gop debate is at risk of losing its draw. the latest on donald trump's double digit lead against his republican rivals is straight ahead. welcome to msnbc's live coverage on this tuesday, july 4th. we start with breaking news overnight. five people are dead and two children injured after a gunman wearing body armor opened fire in a philadelphia neighborhood. police first responded to the attack just before 8:30 p.m. after reports of gunfire in multiple locations. officers arrived on the scene and began chasing the suspected gunman who continued firing and didn't stop until he was cornered in an alley. that is where he surrendered.

about 50 spent shell casings were found in the area which covers a two by four block stretch. the people were all adult men. the two injured children are boys ages 2 and 13. and they are now stable at a local hospital. let's go live to philadelphia and nbc news correspondent george solis. certainly not the headline we want to lead with on this holiday. what more are police telling you about the suspect and how this all went down? >> reporter: yeah, good morning. obviouslyerse very bleak and very harrowing for a lot of families waking up this fourth of july weekend. as you mentioned, new details are emerging as this investigation is just beginning. initially, police saying those four men were shot and killed at the scene while that 2-year-old, that toddler and 13-year-old, were injured and rushed to the hospital. new details were emerging this morning about the fifth man, actually found inside of a home near where this initial shooting took place. they believe he may have been

gunned down during this mass shooting incident. this morning, yet another community in america reeling from a mass shooting. after a gunman opened fire in philadelphia. shooting seven people, killing five, and injuring two children. >> all units use caution. >> reporter: police say the suspect was armed with an ar-15 style rifle and a handgun, wearing a bulletproof vest. the suspect still firing as police were at the scene. >> as they were scooping up the victims and preparing them for transport to the hospital, they also heard multiple gunshots up the street. >> reporter: officers chasing down the suspect, finally cornering him in an alley. >> investigators say they currently do not have a motive in the shootings and do not know if the suspect is connected to any of the victims. police also taking a second person into custody. >> we have another person that

we believe acquired a gun somehow, don't know how, and picked up the gun and returned fire in the direction of the shooter that we have in custody. >> reporter: this incident comes just one day after two other mass shootings. in baltimore, where a community block party descended into chaos as gunfire erupted, killing two and injuring two others, and in wichita, kansas, nine people shot and wounded at a nightclub. in philadelphia, the mayor saying he's horrified by the shooting, writing my heart is with the loved ones and families of everyone involved. i sent my prayers to the victims. this crime scene is pretty expansive. authorities will be back out there this morning canvassing for more clues. at this point, police have not released the names of the two suspects they apprehended. no word on a motive as the investigation is just beginning. >> never seems to end. hopefully those two children

make a quick recovery. george solis live in philadelphia, thank you so much. south from philadelphia to baltimore, where the manhunt continues for at least two suspects who used as many as three weapons in a mass shooting there over the weekend. two people were killed and 28 others injured after gunfire rang out at a block party just after midnight on sunday. police continue to interview several survivors. many of whom are juveniles, about what exactly happened during that party. police say in addition to finding those responsible, they are concerned over and certainly preparing for possible retaliation. turning to politics now. republican presidential hopefuls are hitting the campaign trail this independence day, visiting the early nominating states. florida governor ron desantis, senator tim scott, north dakota governor doug burgm, and will hurd will all make appearances

at a parade in new hampshire. mike pence, former arkansas governor asa hutchinson, and francis suarez will spend the day in iowa. meanwhile, a top spokesman for ron desantis' superpac is raising flags about the florida governor's ability to overtake donald trump in the race for the republican presidential nomination. calling the desantis campaign the, quote, clear underdog in a twitter spaces event recorded on sunday night. never back down, pac spokesman steve cortez admitted that desantis is way behind in national polling. he said, quote, i believe in being blunt and honest. it is an uphill battle, but clearly, donald trump is the runaway front-runner. joining us, white house reporter for "the washington post," tyler pager. tyler, first of all, happy fourth. you don't get a holiday off, i guess, but we're seeing republican candidates really ramp up their presidential

campaigns as we have the last few months. but i want to ask you about biden. how is his campaign looking? and is his messaging changing at all following last week's supreme court decisions? >> happy fourth to you as well. thanks for having me. biden is taking the trappings and power of incumbency to the full advantage. today he'll host thousands on the south lawn of the white house to celebrate fourth of july and give a speech to the american people. we don't expect it to be overly political, but in essence, everything he does as president, as a candidate for re-election, is viewed in that lens. he's not going to be out walking in the parade route. that's the tried and true method of many presidential hopefuls, but his campaign schedule looks different from those running for the republican nomination. he does not have a competitive democratic primary. there's no concerns about his ability to win the democratic

nomination at this point. a lot of his time right now is focused on official events as president, and then fund-raising, as we saw the end of the fiscal quarter, biden fanned out across the country, often doing two fund-raisers a day, trying to build that stockpile of cash as he staffs up the campaign for what is expected to be a long and bruising general election once there is a confirmed republican opponent. >> long and bruising is right. i think chris christie recently referred to some of what was going on between desantis and trump as compared it to teenage food fight. do you think biden is really letting all that play out and sort of letting them argue and argue within the party and then he can sort of focus on the job at task, which is being president of the united states? >> exactly. that's what my conversations with white house sources and campaign sources have made clear over the last several months. they see no advantage to biden wading into the middle of the

fights. they're eager to have republicans beat up on one another and try to take each other down, particularly take donald trump down as they seek to make up ground. i think the quote you read there from ron desantis' pac spokesman is right, that all these candidates are chasing donald trump and they see the difficulty in doing so. i think it's made even more apparent with the fact that they do not know how to differentiate themselves from donald trump, so the white house, biden campaign aides are eager to see how this unfolds and at the same time letting biden focus on cutting ribbons, touting bipartisan achievements in congress, and especially in recent weeks, talking explicitly about the economy and his vision to continue to see it grow and benefit the american people. >> and tyler, just looking ahead, the president also has a big trip to europe scheduled for next week. ought is the main focus of that visit? >> the main focus is the nato summit in lithuania, it's book

ended by visits to the united kingdom where he'll meet with the prime minister, expected to meet with the king, and a trip as well to finland. in the middle is theinate so summit where the president will meet with nato allies. a big focus is russia's ongoing invasion in ukraine, the fallout from the attempted coup from the wagner group there. so a lot of focus on rallying the allies, insuring that there's stability in the west and they continue to support ukraine. that will be the main focus for the trip starting this sunday. >> looking forward to that. white house reporter for "the washington post," tyler pager, thank you so much. and severe storms are impacting millions of people across the mid-atlantic and northern plains. this as millions more across parts of the south and west remain under heat alerts. joining us now, nbc news correspondent emily aqaeda. the stormy weather and stifling

heat will linger today in some regions which is disappointing because people have a lot of celebrations planned. is this going to impact the celebratios at all? >> it could be hit or miss. happy fourth to you. in a matter of hours we'll see more than 60,000 shells launched from bargers floating on the east river behind me to light up the night sky in the largest fireworks display for july 4th in the country. as you mentioned, the big question, will weather interfere in these displays. that's what so many americans are thinking about as they face stormy weather and stifling heat. it could hamper the holiday. this morning, americans celebrating the fourth even as wild weather hits the country coast to coast. this massive funnel forming in the northern plains, as strong winds and torrential rain drenched parts of the south and northeast overnight. a one-two punch of severe weather, for some communities already battered by deadly storms over the weekend.

meantime, the chicago area still cleaning up from up to nine inches of rain sunday. >> this is the strongest downpour of rain since 1987. >> reporter: the unrelenting storms throwing a wrench into fourth of july plans, delaying some fireworks shows in massachusetts. >> the weather does its own thing every year. so sometimes you get lucky, sometimes you don't. >> reporter: but new york city's iconic macy's fourth of july fireworks still hoping to light up the sky. macy's telling nbc news they have done shows in the rain before. adding, we will determine what steps to take in the event of severe weather such as lightning. meanwhile, 31 million americans are sweating it out with heat alerts impacting parts of the south and the west. authorities say a 57-year-old woman died during an eight-mile hike in the grand canyon, with temps topping 100 degrees. cities like las vegas and phoenix expected again to top triple digits today. the extreme temperatures fueling fast moving flames in washington

state. with fears that risk of wildfire may increase during july 4th celebrations. in salt lake city for the first time they're replacing fireworks with a drone show. in flagstaff, arizona, a laser light show takes the place of pyrotechnics. no matter what happens, the american spirit will find a way to celebrate our nation's birthday. >> it would be great if it's the fourth, but it's the whole month, the whole year. we live in the best country in the world. >> reporter: while mild air quality alerts will linger in the midwest and los angeles, here in new york city, we're finally seeing air quality return to healthy levels after days of hazy skies from canadian wildfires and pollution. new york's governor encouraging people to celebrate outside today. we'll have to see to what degree the rain allows. >> all right, thank you so much. well, coming up, a frightening scene off the coast of long island where a teenage

surfer was attacked by a shark, and it wasn't the only incident yesterday. we'll have the latest. plus, a live report from los angeles where thousands of hotel workers are spending july 4th on the picket line. the latest on that ongoing strike, when msnbc's live coverage comes right back in just one minute.

took place right here off robert moses beach. this morning, lifeguards aren't letting people in the water. they have red flags up. they haven't told us why. that could be rip currents, put we also know they're flying a drone which they flew yesterday to look for sharks. this is one of the most popular beaches in the new york city area. it is going to be crowded here for sure today. and this news might give beachgoers pause. this morning, fresh shark fears off the coast of new york. prompting new warnings for beachgoers heading out to celebrate the july 4th holiday. >> shark attack at the lifeguard station. rescue's been notified. >> reporter: two incidents happening just seven miles apart. on monday, long island police responded to calls of a shark attack at kismet beach on fire island. police say a 15-year-old boy was surfing when he was bitten. puncturing his left heel and toes. >> he was able to swim to shore where our marine gear and a good

samaritan were able to assist him and get him over to a local hospital where he's recovering. with non-life threatening injuries. >> reporter: earlier in the day at robert moses state park, officials say a 15-year-old girl was treated for three small bite wounds on her left leg. >> we heard a whistle blee, screaming everyone to get out. >> reporter: it's unknown what bit her. authorities say a state park's drone was immediately deployed but was unable to detect any, quote, dangerous marine life, including sharks, in the area. though shark attacks are still very rare, there have been multiple encounters this summer, including three in florida in a little over a week. and back near long island, there's been a recent increase of tiger and sand sharks swimming closer to shore. >> i think it's crazy. there's been a lot of shark attacks happening on the beaches, been a lot of warnings. >> reporter: a warning to those headed out to catch a wave and soak up the sun this holiday week. be aware of your surroundings. >> if you see something that

looks like some type of shark or one of these bunker fish that swim in these pods, it's probably a good idea to leave the water and notify some type of authority. >> reporter: researchers at the university of miami did a really fascinating study. they looked at, this was in 2022, they looked at whether sharks were deterred by lots of activity at the beach or perhaps city scenes where there's lots of hustle and bustle. they thought maybe sharks would choose not to go in those areas. what they found is sharks are actually attracted to those areas. but they said this is good news because that means that there are sharks in the water, and shark bites are incredibly rare. so it means that sharks are out there, they're swimming around, but they actually don't have any interest in attacking you. >> okay, that's very good news. so i'll be in the ocean later this week. thank you so much, stephanie gosk. still ahead, our next guest served in the u.s. military in iraq before serving pennsylvania in congress.

we'll speak with democrat chris deloseio about his new piece on patriotism as we mark this july 4th holiday. msnbc live is coming right back. i'm jayson. i'm living with hiv and i'm on cabenuva. it helps keep me undetectable. for adults who are undetectable, cabenuva is the only complete, long-acting hiv treatment you can get every other month. cabenuva is two injections, given by my healthcare provider, every other month. it's really nice not to have to rush home and take a daily hiv pill. don't receive cabenuva if you're allergic to its ingredients or if you taking certain medicines, which may interact with cabenuva. serious side effects include allergic reactions post-injection reactions, liver problems, and depression. if you have a rash and other allergic reaction symptoms, stop cabenuva and get medical help right away. tell your doctor if you have liver problems or mental health concerns, and if you are pregnant, breastfeeding, or considering pregnancy. some of the most common side effects include injection-site reactions, fever, and tiredness. if you switch to cabenuva, attend all treatment appointments.

ready to treat your hiv in a different way? ask your doctor about every-other-month cabenuva. every other month, and i'm good to go. for too long, big oil companies have bought off politicians so they can get away with ripping us off. that's changing now. joe biden passed a plan to jumpstart clean energy production in america. it's creating good jobs that can't be outsourced and will lower energy costs. $1800. that's how much a new report says the inflation reduction act could save just the average american family on energy costs.

a ukrainian deputy defense minister says their troops are making minor gains on multiple fronts, but the fighting remains fierce. the minister said yesterday, ukrainian forces were able to retake 3 1/2 square miles of

land in eastern ukraine and that the forces were able to resist increased attacks from the russian military. meanwhile, in southern ukraine, the same minister reported forces there were able to recapture nearly 11 square miles in the past week. she added that offensive actions were continuing toward two cities in the south that the russians have long occupied. nbc news is not able to independently verify the minister's comments. joining us now, democratic congressman chris deluzio of pennsylvania. he serves on the armed services and veterans affairs committees. and is an iraq war veteran. happy fourth to you and thanks for being here. i wanted to talk to you about a new op-ed that you wrote. you call on americans to, quote, reclaim patriotism from the extreme forces in our country. i thought the article was extremely interesting and well written. for those of us who haven't read

it, can you explain what you meant by that? >> of course. and thank you. i think so many of us have gotten used to the folks on the far, far right, the most extreme people in this country wraps themselves up in the flag. literally, the stars and stripes, acting as though they somehow have a monopoly on love of this country and patriotism. it's the same folks i see fanning the flames of insurrection, lying about election results, attacking our freedom. they're not behaving in any way i understand as being patriotic. i'm from western pennsylvania. we fought our country's wars and so much else. we love this country as so many across america do. i think it's incumbent on all of us to reclaim that, to talk about love of country and ground it in our politics. that's what i do all the time. i bring my service, my background of being in uniform and fighting for our common good, that's what patriotism demands. i think we as members, that's

why we're in this business and what our values are. >> i know you mentioned in the article it's all of our responsibilities to preserve democracy, and really what this country was built on, and that didn't happen, as you mentioned, on january 6th. during the insurrection. can you talk about going forward and what you would like to see people define patriotism as? >> look, i think people, especially people running for office, you have got to be willing to confront anti-democratic forces in your own house. i have republican colleagues who have voted to overthrow an election. voted to kick out pennsylvanians votes, who are willing to embrace trump and others who tried to overthrow our constitution. and so for me, loving this country has to also mean committing to the rule of law and the constitution. i think beyond that, service is such an important part of love of this country.

it's not just folks who serve in uniform as i and so many others did. whether it's your volunteering at a local school, a cop, a firefighter, a teacher, you name it, so many ways where people are committed to serving this country and we ought to uplift those folks and talk about those stories. >> certainly voting is one way you can contribute as well. i want to mention you and several of your colleagues introduced the mark fogle act in the last week. can you tell us a little bit more about who mark is and what this bill seeks to do? >> mark unfortunately has been detained in russia now for nearly two years. constituents of mine in western pennsylvania. a guy from western pennsylvania with family here. was detained for having a small amount of marijuana that he had a prescription to have for pain. and he's been in a penal colony in russia since he's been convicted there. and we have been calling for his designation as being wrongfully detained which is a very important designation that then

gets our government to really advocate for his release. we haven't seen that happen so i introduced this bill with democratic and republican colleagues of mine here in pennsylvania to get more transparency from the state department and to push them to consider designating him as wrongfully detained. >> and i just want -- there's a picture of him right there. what would happen if that does pass? tell us what the next steps would be. >> if we get this law threw, we get more transparency in congress on how the state department makes this decision. sharing information with us, telling us about the criteria that are out there under current law, how they're being met or not. and doing that within six months of someone being detained in another country. for mark, he has been detained for far longer than that, he spent much of his career as an adult teaching abroad. and so this law, this bill y think, will help people like mark who our government and folks ought to know, the government doesn't forget them,

their members of congress don't forget them and we're fighting to get them home. >> finally, i just want to get your thoughts on last night's mass shooting in your home state, in the city of philadelphia. what do you have to say tothose who continue to oppose serious gun reform legislation in congress? it just, i mean, we're on the anniversary of something that happened last year, mass shooting, and we had one over the weekend. >> if you don't have a spine, get out of the way. we'll continue having dead kids and dead people until people in congress on the right start acting like this is a crisis. it is a crisis. they're more willing to cozy up to gun manufacturers and the nrbs ra than they are to protect our kids. it's obscene. i served overseas. we had the best training in the world carrying weapons just like the ones we see in almost all of these mass shootings. they don't belong in our streets and our schools. you can walk in as an 18-year-old in most states and buy a gun like the one we carried in iraq. it's insane. most of the american people know we need to change this.

our republican colleagues need to get out of the way or help us make something safer and different. >> our children certainly don't deserve it. chris deluzio, thank you so much and happy fourth to you. for years even as the number of new military recruits fell, the armed services could depend on children of military families joining up. now pipeline of new service member is drying up with an increase of veterans and even active duty officers telling their children the military may not be for them. the "wall street journal" reports today nearly 80% of all new army recruits have a family member who has served in uniform, according to the service, only 9% of young people ages 16 to 21 said last year they would consider military service. that's down from 13% before the pandemic, according to pentagon data. the u.s. army, navy, and air force all anticipate missing their recruitment goals this

year by thousands. only the marines expect to hit its goals, but even that branch says it has been challenging. joining us now, president of the travis mannion foundation, ryan mannion. and it's so nice to see you. and happy fourth. i know you lost your brother, travis mannion, during a tour in iraq. can you tell us a little bit about him and why his legacy led you to create this foundation which i know you are so passionate about? >> thanks so much, erin. yes, my brother was a first lieutenant in the united states marine tour. served proudly two tours in iraq and was killed in his second tour of duty while pulling to safety two of his wounded teammates. so we started the travis mannion foundation because we wanted to highlight how important it is to make sure that these men and women and their stories are continuing to be told and that we're supporting our entire

military community. >> so what do you think about this article that we just quoted from the "wall street journal" saying that even family members of the military may not feel that it is the best spot for their children? i mean, i get that this has been your life's work, and that probably is a little disheartening to see that. >> yeah, you know, i read the article. and while a little of that may be true, i think if you look at the stats that 80% of army recruits have a parent serving in the military, i think that tells a little bit of a different story. the story is that, you know, parents are passing down their experience in the military as a positive one, largely, if 80% of army recruits have parents that served. my brother served and my brother learned about service because my dad is a retired marine corps colonel. my dad talks a lot about when he was growing up, he was -- his dad was a world war ii veteran, his coach was a veteran.

the butcher was a veteran. his teacher was a veteran. i think there's one thing missing here, if you look at in 1995, there were 40% of our population had a parent that served in the military. today, that percentage is 13%. so if you look at it from a holistic standpoint, we need to actually put veterans back in front of our young adults to talk to them about military service and not make it so stigmatized and taboo. right now, they don't feel this connection to the military. they don't understand the benefits that serving in the military can afford them. they don't understand what it means to be a veteran. that's what we do at the travis mannion foundation. we put veterans in front of our next generation. to talk to them about service and sacrifice, leadership, courage. not so much to indoctrinate them to join the military, but to share with them what it means to be a servant leader, what it means, what service ultimately means.

if we keep putting these ideas back in front of kids, if we keep putting veterans in front of our youth, we'll see the numbers change drastically. >> you do a lot to help recruiting in a variety of ways. we thank you for that, and president of the travis mannion foundation, ryan mannion, thank you for all that you do. >> thanks. still ahead, new developments in the republican race for president. the candidates who want to debate may not qualify. and the candidates who do qualify might not want to debate. how the rnc is trying to handle that balancing act when msnbc's live coverage comes right back. i brought in ensure max protein with 30g of protein. those who tried me felt more energy in just two weeks. uh... here i'll take that. -everyone: woo hoo! ensure max protein with 30 grams of protein, one gram of sugar. enter the nourishing moments giveaway for a chance to win $10,000. how can you sleep on such a firm setting? gab, mine is almost the same as yours. giveaway for a chance to win

i feel clearer in my thoughts, my memory has improved and generally just more on point. prevagen. at stores everywhere without a prescription.

with the first republican primary debate just 50 days away. many are wondering just how many candidates will make it to the debate stage. in the summer of 2015, ten republican primary candidates filled the stage for the first primetime debate of the election cycle. but a new piece in politico highlights the rnc's new polling and fund-raising guidelines that are making it harder for many of the candidates to qualify this august. and donald trump, the front-runner in the field, is hinting he may be a no-show. joining us now is one of the authors of that article, politico reporter alex einset. this is interesting because when

we look back, we saw all those candidates on the stage. and now, it seems far fewer are qualified or meet the requirements for being part of the debate, and the guy who has met all those requirements says he doesn't really want to be a part of it. what's going on? >> it's a really fascinating dynamic here in that you might have a really small group of people on the debate stage when republicans meet for their first debate next month in milwaukee. a lot of republicans running in this race, but as you mention, trump is saying he may not want to show up. there are other candidates who may not qualify, and there are even questions as to whether the second person running in the race, running behind trump, ron desantis, will even show up. that's really created a dynamic of uncertainty. who will show up for this debate? >> i think it also begs the question, is this debate going to be relevant? if you have two of the most notable names who are saying, yeah, we met all the criteria,

but we really don't think it's going to help us to be part of the debate, what does that say about where we are and not being able to have these intellectual conversations and platforms where voters can make educated decisions? >> absolutely, and it could have a real impact on the race, right? you have donald trump running in first here, but then you have these other candidates who really see the debate as their biggest opening. in the sense it's their best option to be on stage with him, and to create contrast with him, and to make arguments against him. this was going to be their main opportunity. by not showing up on the debate stage, trump is robbing them potentially should he not show up of that opportunity to make up ground against him, potentially. >> and desantis and trump have sort of been battling it out and debating unofficially if you want to call it debating off camera and off the stage. you have chris christie who has received some accolades for how he's been handling everything so

far. as he puts his hat in the ring. but he doesn't -- he's not qualified -- he's not meeting the requirements right now to be part of the debate, is he? >> there are big questions about whether chris christie will be able to qualify for this debate because as you mentioned, there are two qualifications that candidates need to meet. one is a polling criterion and another is a donor criterion that states you need to have 40,000 donors in order to get on the debate stage. for a candidate like chris christie, it could make it harder to get on the debate stage. and there's other candidates who might struggle, whether it's something like mike pence. there are questions as to whether some of these candidates are going to be able to meet the donor threshold and potentially the polling threshold needed to get on stage. that's going to create potentially the dynamic of a shrunking debate stage. >> we're looking forward to the fireworks in august. alex, thank you so much for joining us. election officials across

the country are sounding the alarm over new certification guidelines for voting machines in future elections. politico reports that after years of aggressive behavior from voters, officials are worried that the new guidelines will only elevate future misinformation. those same officials are pushing for a 50-state media strategy rollout to help communicate what is being implemented to ease the public's concerns. the new standards will be introduced this november and represent a huge leap in requirements on things from cybersecurity to voters with disabilities. however, nearly every system in use in 2024 will be certified under the current standards. joining us now, state politics reporter at politico, zach montalaro. this is a complicated issue as well, and what struck me was they're not just working on refiguring sort of the way

people vote but also the pr message. they're afraid to use certain words because they don't want people to, for lack of a better word, freak out at the changes they're trying to implement. >> that's exactly it. for the last 2 1/2 years since the 2020 election, we have really, really seen from former president trump and his allies an attack on voting machines. we saw the former president claiming votes are stolen. we saw fake audits across the country that all target these election machines. so while these new certification guidelines are good and election officials believe they're a big step forward, they have major concerns about how they talk about it, that the word choices they use really matter because there's a certain part of the american population that's already predisposed to not trust this equipment. now that they're changing the rules and the way they're certified, they worry those same people could freak out even more. >> just break down for us what these new guidelines for certification are and sort of

the timeline for when they will go into effect because from what i understand, 2024 may not be a possibility. >> right. so these guidelines were voted in in 2021. and they go into effect at the end of this year, in 2023. just because they're in effect, just because they're the only guidelines that exist, doesn't mean machines will be certified to them. everything we vote on in 2024 will be certified under the previous guidelines. they're still secure, but the new guidelines will go into effect. but equipment just won't be built. it takes a long time to built election equipment. it takes a long time for state and local governments to buy equipment. so there's no way this will actually be used next year in the elections. >> all right, zach, thank you so much and happy fourth of july. >> happy fourth. up next, it's not just hollywood writers who are striking right now. thousands of hotel workers are demanding higher pay and hitting the picket line in california. we'll go live to los angeles straight ahead.

there would be more visibility and more impact on the hotels. >> reporter: actually, it just happened coincidentally, because the contract expired right before this weekend. at that point, the workers went on strike knowing their voices would have a huge impact. the largest hotel in los angeles was lucky enough to reach a deal with its employers right before the weekend, but dozens of other hotels are impacted this weekend. now that negotiations are at a standstill, based on what happens here, you may see a domino effect across the country with more hotel employees demanding more. major chains are being impacted by this. if they see los angeles employees getting a raise, they may want one too. >> thank you so much.
