people are scared. political violence. whatever. happening with the border. really mingles to people being unsafe or feeling unsafe safety and crime. top of mind. president trump will be addressing those, but the tone is going to be much different. campaign say they're working towards unity. i hope that new tone it carries on into fall. it's very important for our country marching forward to try to win over voters. think we have to show a little bit of and culture.

>liz>both major presidential campaigns are trying to find a way forward as we look for answers about the shooting on former president donald trump. so how does this change? what was already a very contentious race and what does it do to are deeply divided electorate? i'll talk with a presidential historian about the magnitude of this moment as in just a few minutes, but first a look at your news headlines. alameda county district attorney pamela price announced an update on the review of 35. death penalty cases over possible possible misconduct from former prosecutors. three cases will be re sentenced, including the case of earnest ..., which triggered the investigation price says he will be released next year on probation. he was on death row for the murder of a nine year old boy in attempted murder of his grandmother back in 1993. the d. a s investigation centers around notes found in case files that appeared to show prosecutors. discriminating against jewish and black

jurors. convicted murderer scott peterson continues to fight for a new trial. he appeared virtually in a san mateo county courtroom today, his lawyers argued. prosecutors are refusing to hand over hundreds of pieces of evidence. the judge has okayed one piece of evidence to be tested. a piece of duct tape bound on his wife's body, peterson was convicted of killing his wife, lacy and their unborn son back in 2002. a makeshift memorial is growing outside a home in alameda. where five family members were shot and killed. we learned yesterday that a one year old died from his injuries days after police say 54 year old shane killian. shot his wife, his in laws and their kids. the other child was just six years old. elon musk said he is moving the headquarters of ex out of san francisco, and he's also moving the headquarters of space x out of l. a, says it's in response to

governor gavin newsom signing a law banning policies that require teachers to tell parents if their child changes their gender identity. no word on when that move will actually happen. the black panther apartments are now open in oakland, the affordable housing project is on seventh street, three blocks from the west oakland bart station seven. units and neighborhood market and urban farm. their founder is the former leader of the black panther party. the rehab hospital at santa clara valley medical center was just ranked as the best in california and number six nationally as that's according to us news and world report, the hospital scored high in treating patients dealing with stroke heart failure, pneumonia and hip fracture. more than 4500 hospitals were evaluated nationwide. factors considered include survival rates, complication, rates and patient experience. all right on the first alert weather now the heat is just around the corner yet again, they're all just

darren peck is looking toward the nineties. >paul>back. i know, but you know what's good about that liz is and you said it right? it's nineties. i don't have a forecast. that brings us back to the kind of heat that we went through for that week and a half stretch where we get up to 110 for inland valleys that's not coming back. but we're only holding on to this wonderful stretch of weather that we've got out there for a few more days and then by by friday, the heat is coming back. look what happened today. this is a replay high resolution. satellite shows you the marine layer getting pulled off the coast and we're all looking at sunshine right now, but watch it build back in again tonight will use that same depiction to show you tomorrow morning. the marine layer is going to feel most of the bay. so we still get some help tomorrow if you look at the daytime highs tomorrow are very similar to today. and these numbers are pretty much right where we should be for this time of year, a lot of mid to upper eighties for the inland valleys. the temperatures in the upper eighties in the north bay by friday. the numbers are going to go up a bit, so we'll take this from wednesday. watch the color code changes a bit. the

numbers go a little bit higher, and now we skipped ahead to friday. and now those numbers are in the nineties. so this is kind of the peak for this week. so thankfully on a technicality. we are staying out of the hundreds. but then there's a 99 degree day in the forecast on friday. for concord. and we are starting to kind of return to that messaging where we start talking about heat related health impacts. so the national weather service is already coloring the map on friday, it's still only orange. we've had plenty of days in orange and orange. in case you've forgotten on this one that tells you there's a moderate degree of health. related heat impacts from this so we're not looking at any of the high yet. by monday of next week, we might start getting a bit closer to that because the pattern is going to start changing for us there's monday and by the time we get to monday, now we are seeing some triple digits on here. livermore. you're going to 100. it'll be close and concord. i know we skipped over the weekend. you're going to see that in the seven day forecast in one second, because the weekend actually pretty much

stays put or even cools down a little bit from friday before we warm back up again on monday, so what i wanted to do was just get you ready for the days that matter. most, and that's going to be this coming friday. and then monday and then probably the first half of next week. things are going to stay pretty active as we transition into this next coming week. let's go to the 70 forecast. we'll show you what that looks like. we'll start out with our inland micro climate. so we've kind of already got our sights on friday monday might not look terribly intense here because it's just kind of like a replay on friday. you do get a nice little reprieve so instead of being near 100 for the weekend, we're going to settle for like, oh, it's low to mid nineties and you're 5 to 7 degrees above average. that's better, especially considering it's a weekend. the heat risk is fairly low for saturday, sunday, but it does start coming back up again. once we get into early next week and just to round out our forecast to show you what somewhat milder numbers look like when you get in the bay and see your forecast will be a bit more comfortable there except santa

rosa got some heat coming, alright for now, liz back to >liz>you. all right, darren. thanks so much as the investigation into the attempted assassination of former president trump continues. so does the republican national convention are and mackovic has the latest on all of it and >ott-1>tonight there's going to be speeches from candidate trump's primary rivals. rhonda santis and nikki haley. she was added to the lineup following saturday's shooting. the theme of the convention today is safety. it's expected to focus on crime and the border delegates are going to be hearing firsthand accounts from people directly impacted by drugs and crime. former president trump's new running mate jd vance did a walk through on the convention floor this afternoon at his side, donald trump jr. is sort of a run through. you on the stage for his big speech, which is planned for wednesday night bounce joined trump in the hall on monday when the former president, brother crowd to its feet his right ear bandaged. following saturday's assassination attempt. and today we're learning more about the moments leading up to that

shooting local law enforcement told cbs news app three snipers from local tactical teams were stationed inside the building. the shooter used in his attack one of them spotted the gunman sitting outside the building, looking at his phone and took a photo, then they saw him looking through a range finder and immediately radioed to the command post. but by the time they called for backup he had scaled the building today. trump senior adviser that declined to comments on calls for the head of the secret service to step down. at president trump very much respects and values the secret service team that is around him. in credits his being alive to >them. >>committee on homeland security announced that it will hold a hearing next week on the circumstances. surrounding that attack. in the meantime, president biden spoke to the end. convention today. he called for unity but also drew contrast. between his policies and trump's including gun control. >we'll speak about violence.

we're going to speak about guns. more. children than men. dying of gunshot wound. that's heading another reason that's coming and that is sick. >ott-1>meantime, the trump campaign announced that he and j. d. vance will hold their first joint rally together sunday, saturday evening in the battleground state of michigan lists. >liz>thanks so much still ahead, a presidential historian joins me to talk about the scope of the recent events and how similar incidents have shaped elections past. plus. where does the presidential race itself? stand? cbs news. polling gives us some insight into where voters stand on some key issues. keep

>liz>yeah. the latest cbs news poll. showed nearly a dead heat between president biden and former president trump in battleground states with a slight advantage for trump. but that was taken before the assassination attempt and the start of the rnc. today i spoke with cbs news director of elections anthony salvato about what democrats need to do to make up ground and what we can expect to hear tonight from the rnc. um i'm going to start with the economy because that's been something that's been advantaged trump throughout this campaign, so this number i think is one to watch for democrats 21% think they would be financially better off if

joe biden wins, but the numbers higher at 46 for if donald trump wins, you're going to hear the republicans at their convention talk a lot about the economy because they know they have that advantage. so they'll probably press it. i think one of the things we'll watch, then over the coming weeks is whether the demo craddick campaign can start to reverse those numbers because the economy is the top issue for everybody. democrat and republican. so you're going to get a lot of pay off if you will, if those numbers start to move list well today, the focus of the rnc will be immigration and border security. curious because you recently did a documentary where you traveled around the country and talk to the voices behind those polls. how big of a concern is immigration on other states. we know it's a big issue here in california. we know it's a big issue in texas and the other border states. but what about the other voters? it's a big issue everywhere, but for different reasons, and i appreciate mentioning our documentary. giving people a chance to voice all the nuance

if you will behind their opinions, immigration, they tell us touches a lot of topics for them. it touches issues of security. it touches issues of the economy. it touches issue of issues of who we are as a nation and a people so to that broader point here's a contrast that i do want to show if you look at among all voters and just the general statement, what do americans do for us society? well, it's kind of split, make it better make it worse. don't have an effect, but some of what you'll hear a lot tonight at the republican convention speaking about immigration, two thirds of republicans say immigrants make american society on balance. worse. and they believe that donald trump's border policies will decrease the number of folks trying to cross the border. so that's a little bit of a primer on what you're going to hear. and perhaps why you're going to hear it at the republican convention tonight, but, yes, it is a top issue across the board for a lot of

voters in a lot of states >liz>list. and let's face it. there's just not that much time before voters actually hit the polls. and while it's a highly emotional time right now, are kerosene here looks at how much the recent events could actually change the outcome. of this election. >the nation is coming to terms with the assassination attempt. a former president donald trump. but how could this impact elections as well? with the political analysts who talked to me about how this could possibly impact the race. months older. if you want to really see something to said, take a look at what happened. video of the assassination attempt on president trump quickly reached millions. the political climate in the us was already tense, but now voters may be grappling with feelings of shock uncertainty and anxiety. after a major act of political violence. >it's very very scary that a gun can be used in a situation

like this. any political party doesn't matter who you are shouldn't be assassinated. i think we have to show a little bit of that. and culture. and, uh, yes, it when we talk about her politics. bobby larson. it is the rare san franciscan committed to voting red this election >day for our country and sad commentary. on where we're at, i guess as a nation, but i'm going to vote for trump. it was already planning to vote for trump the assassination attempts solidified. his support. we talked to cal state history and communications professor dr nolan higdon for some perspective on the impact of political violence, he said. a bump in support. is normal. >usually approval numbers do increase after these type of events america has seen this type of reaction before with other historical events like 911 and the last presidential assassination attempt in 1981 with ronald reagan. >asked, but somewhere around 8 to 10 to 15 points in the

polls is what he jumped after the shooting attempt. but increased approval may not translate to the voting booth. especially not for young voters. >see a lot of, um polling or focused on the apathy of young voters over the last year, so one thing that the american electorate seems to agree upon is that they really don't like either of these candidates. going into the election. young people in particular. says it's up to the politicians to inspire the electorate show up at the >booth. >>join me now live is presidential historian douglas brinkley. thank you so much for being with us. can you think of another time in our nation's history where we have been this divided as a country? >live>you only really go back to the civil war when lincoln was elected in 1860. he wasn't even on the ballot and most of the southern states he had to be snuck in the washington dc, from springfield, illinois. even using body doubles for fear of assassins and those

days, the executive mansion. it wasn't called the white house took theodore roosevelt named it that it was called the executive mansion, and it was so weak on security. they were goats, grazing and people coming and running right up to the front door. and you know, even entering from time to time, so lincoln had to live with that fear. and with our country divided. of course, we're not at a super war time. i don't want to make the comparison. but there is a kind of heated rhetoric on the land that's frightening and we at all costs, all of us, no matter how you vote, or whether you're a democrat republican. independent on matter. we've got to all denounced political violence right now and be ardent about that. >liz>support to note there have been other assassination. temps on presidents and presidential candidates. what impact did they have on those elections? >live>well, you know, in 1933. people don't talk about this franklin roosevelt just one and we used to not inaugural, great presidents to march, so he won

32 election. now it's early 33. and right before his inauguration. miami somebody tried to shoot fdr instead. they killed the mayor of chicago and other people all around fdr were shot down. and yet fdr was unscathed yet rushed to the hospital. you think about george wallace say 1972. running for the democratic nomination and and was shot in maryland. than paralyzed? for life? we saw gabby giffords, a congresswoman. and arizona. and recent times has was shot. um and and and deeply hurt by the bullet wounds, so it's perilous out there. it's right, really, though it 1968 rings people's bells because of that moment when both dr martin luther king jr and robert f. kennedy were killed within just a few short weeks, and it led to a summer of anarchy, particularly at the democratic convention in 68.

>liz>the fbi says violent political rhetoric is actually ticking up after this assassination attempt. but do you think there's any chance to its history? give us any kind of hope that events like these can actually soften the contention between the two parties, at least briefly. >live>um, i think it has briefly by and large on at least on the main game of public discourse. everybody's kind of cold their jets for the last few days. but, alas, you know, the secret service was established because william mckinley was assassinated. in in the beginning of the 20th century and buffalo and then when kennedy was assassinated in 1963, dallas, the secret service was mandated to protect perimeters, meaning no way whatever again, somebody a be able to get into a building like as we did. but here we are seeing a security lapse and a butler. pennsylvania. the buck stops with the secret service. they may be. we're trying to farm it out to local law enforcement but to have nobody

monitoring a basically a platform. 150 yards away. um, it's not acceptable so i think our security now and the rest of the campaign has to be empty up and the secret service soon. skeptical from 4008. agents internationally. that are operating to about 4500 did we need to invest in our secret service. and because we can't have a repeat of butler. >liz>i want to give this one last question and because president joe biden is in vegas today, members of his own party's is still calling on him to step down. although that volume has has has lowered at least temporarily, but can you think of a time when there was that kind of concern this close to a convention and an election on the presidential candidate? >live>well back in the 19th century or really, you know, there used to be the smoke filled rooms and you know, and then suddenly, the conventions would occur in wheeling and dealings. come on. but since the the ad advent of television can correct the connections are meant to be infomercials. um

and you're seeing that play out right now in milwaukee. so you know the that the closest thing to what i saw was the democratic party came unglued. and 1980 when sitting president jimmy carter was challenged by ted kennedy and this case, it's an anti biden movement in the democratic party without one reap clear. replacement. if you like governor newsom era matching president newsom something, kamala harris should be automatically upgraded banking step. step down, but what will end where we began with lincoln lincoln's famous a house divided cannot stand a democratic party divided right now cannot stand. they've got to make a decision. biden or not, biden pretty quickly. >liz>alright, presidential historian douglas brinkley. thank you so much for that perspective and joining us today, sir. all right, still ahead a unique perspective on the security in place during trump's rally on saturday,
