i'm carris sa lawson in new york. these are the top stories on "cbs news roundup." kamala harris is in chicago ahead of her star turn at the democratic national convention. u.s. secretary of state antony blinken takes his message to the middle east, pressing for a cease-fire deal ending the gaza conflict. and former republican congressman george santos is expected to plead guilty to corruption charges. the document nominee vice president kamala harris has been riding a whirlwind of support during her short four-week campaign setting fund-raising records and attracting large crowds. on the eve of her party's convention our new poll shows a very tight race. take a look at this. vice president harris is three points ahead of former president donald trump nationwide. but in those seven key battleground states the race is a dead heat. pennsylvania is the biggest battleground. cbs's weijia jiang is there. >> reporter: from pittsburgh vice president harris and her

running mate tim walz took off for a campaign blitz by bus through pennsylvania, surprising supporters at a phone bank. >> how are you doing, hannah? >> reporter: and visiting with volunteers on the ground. >> through these next 79 days we will continue to build community, build coalitions, and remind each other we are all in this together. >> reporter: kim haskins was thrilled to attend an event in coraopolis. >> she brought life back into my party. >> reporter: our cbs news poll shows men are more likely to vote for former president trump and women for harris. including lisa short. >> do you think it's going to be a close race here in pennsylvania? >> i think it's really going to be a close race because i've been here my whole life and what i've noticed is like trump comes here a lot. so i really think like it's going to be tough for her to win pennsylvania. >> kamala, you're fired! get out of there. >> reporter: trump campaigned in

wilkes-barre, slamming harris's appearance. >> i say that i am much better-looking than her. >> reporter: her laugh. >> that is the laugh of a crazy person. it's the laugh of a lunatic. >> reporter: and her economic policy proposals. >> this is communist. this is marxist. this is fascist. >> reporter: according to our poll voters think trump's policies will have more of an impact on the border and on bringing down the price of food and groceries. a big reason why mary beth scarramastro and louis cohut plan to vote for him. >> the economy is horrible. we need change. we need to go back to where we were four years ago. >> we're headed off a cliff as far as the economy goes. >> reporter: but the harris-walz campaign believes they can flip the state back to blue. >> we're back! and we're going to keep coming back. >> reporter: speaking of coming back to pennsylvania, on monday both trump and his running mate j.d. vance have events scheduled here. meanwhile, harris and walz are heading to chicag to kick off the dnc convention.

weijia jiang, cbs news, coraopolis, pennsylvania. as weijia just mentioned, the democratic national convention is coming up, and delegates are gathering in chicago. organizers have been pretty busy preparing for the political show inside the united center and finalizing the roster of speakers. cbs's ed o'keefe is there covering it all. >> reporter: among those set to adress the convention is former first lady michelle obama, her husband the former president barack obama speaks to the crowd tuesday night. wednesday it's former president bill clinton and walz. thursday harris formally accepts the nomination. our cbs news poll finds the reason the race between her and former president donald trump is tightening is because she's gained support from younger voters and voters of color. that's why this convention's big theme is focused on the future of the country. but our poll also finds fewer voters know what harris stands for. about a third don't quite know. that's one of the challenges for democrats in the coming days, reintroducing harris to the country and explaining what she would do if she wins.

>> that was cbs's ed o'keefe. our coverage of the democratic national convention in chicago begins monday evening at 5:00 p.m. eastern on cbs news 24/7 and right here on cbs at 10:00 p.m. eastern. schedule for this week will be high stakes meetings aimed at securing a gaza cease-fire. secretary of state antony blinken is in israel ahead of a meeting with israeli prime minister benjamin netanyahu. blinken's goal is to intensify diplomatic pressure, hoping to end this ten-month-old conflict. cbs's ramy inocencio reports from tel aviv, where he says israeli attacks on palestinians in gaza killed at least 29 more people in just the last few days, including this strike caught on camera. >> reporter: you can just see that man and child running for cover. two missiles hitting that apartment in neuse rat in central gaza. up and down the strip there was despair and disbelief. these two boys called baba, baba

my beloved dad is gone. one of them shaking his body as if trying to wake him up after a strike on khan younis. in a separate strike nearby this man pulled three lifeless shrapnel-scarred girls from the back of his car. we've had to blur this video. their tent was hit in the al mawasi camp which israel's military has said time and again that it is a safe zone. and a strike on a home in central deir al bala killed a mother and her six children. five of them were quintuplets. take a look at this body bag. there are six names there. all of those children fit inside this one single bag. local israeli media are reporting that netanyahu was pessimistic with his ministers and said there were no high chances for a deal. not only that, hamas has also issued a statement that was pessimistic too saying that netanyahu is still placing obstacles to reaching an agreement and setting new conditions and demands with the aim of prolonging the war. ramy inocencio, cbs news, tel aviv. there are some new legal developments involving ousted republican congressman george

santos. cbs news has learned santos is expected in federal court later on monday to plead guilty to corruption charges that drove him from office. cbs's shanelle kaul reports. >> reporter: defiant for months. >> i'm still fighting. i'm still standing. >> reporter: but now an apparent about-face from ousted former new york congressman george santos. >> i'll set the record straight when it's convenient to me, not to you. >> reporter: cbs news has learned santos intends to plead guilty monday to felony charges tied to a federal corruption case accusing him of fraud, identity theft, and misusing campaign funds. his trial was set to begin september 9th. >> why plead guilty now? >> a plea deal would allow george santos to avoid the circus. >> reporter: santos was first indicted in may of 2023, pleading not guilty. ten more charges came in october. he was ousted from congress in december. he admitted to lying about his

education, family life and career. but this case is about campaign dollars. >> what would a plea deal look like here? >> george santos faced a maximum of decades in prison. so a plea deal would likely look like a lot less time in prison than that. >> reporter: right now it's unclear which of the 23 felony charges santos may plead guilty to, and if he'll actually show up in court. shanelle kaul, cbs news, new york. when "cbs news roundup" continues, details on new laws in california aimed at tackling professional smash and grab crime rings.

people who steal property worth more than $40 will be charged with a felony instead of a misdemeanor starting in october. right now in california that threshold is $950. some business owners want to see it lowered. >> it has to stop. because we're all fed up with it. >> reporter: elise preston, cbs news, los angeles. about 100 people sought out emergency medical treatment for extreme heat in colorado over the weekend. this happened at the pikes peak air show in colorado springs. most were treated at the scene, but ten were rushed to the hospital. treating heat-related illness quickly is key to survival. in fact, national recommendations call for cooling patients first before transporting them. but environmental correspondent david schechter find most states do not require that life-saving protocol. >> reporter: lots of ice. when you stack up matt whelans against most paramedics, he has one more life-saving tool for

patients overcome by the blazing texas heat. >> you're the ice man. can i be maverick? or how are we going to do that? >> you can be maverick. >> okay, cool. >> reporter: matt carries that ice with him every day in case there's a call for heatstroke. >> i'm going to be part of the crew here for a little bit and learn how they do this, how they cool a patient down on the spot. >> on the count of three. one, two, three. up. and move over. >> reporter: i help matt put the patient in a bag. >> we can start dumping this on him. >> reporter: pouring water. >> literally dump the bucket of ice on them? >> dump the bucket of ice on him. >> reporter: pour in matt's ice. >> really it's very simple. >> yes. now we're treating them in the field and making that difference. >> and that could save their life. >> that is going to save their life. >> reporter: the protocol is known as cool first transport second. the national association of ems officials recommends if a patient's core temperature is above 104 an ice bath immersion

provides the most rapid cooling mechanism. only after the temperature falls to 102.2 should the patient be transported to the hospital. it's a life-saving intervention that's more critical than ever as climate change makes our summers hotter and hotter. >> tell me about -- tell me about zack. >> i love talking about zack. for his age he was always very big. and gentle and kind and funny. >> reporter: they called him big zack. and during football practice in 2017 zack's body temperature hit 107 degrees. when the ambulance arrived, he was unresponsive and moaning. >> i just remember the panic that was setting in in that moment. they were just assessing him and then loading him up -- >> the instinct is let's get to the hospital. >> load and go. >> reporter: but when a patient is overheated, the national

recommendation is not load and go, it's cool first, transport second. however, across the country only 11 states require ambulance services to follow that life-saving protocol. zack tied from organ failure 11 days after he collapsed. his mom believes if cool first transport second had been followed he might have survived. >> you know, as a mother that first heartbeat is really important to hear on the sonogram. i heard his last heartbeat too. >> i am laurie giordano. i am zack martin's mom. >> reporter: after years of advocacy, laurie worked with the florida legislature to pass what they named the zachary martin act. a law requiring among other things on-site ice baths at all outdoor athletic events in florida. but she's not stopping at high school sports. she wants all of the nation's ambulances to cool heat victims
