he has threatened legal action if things don't get better. and this afternoon, governor newsom is doing his part to create more safe and affordable housing for farm workers across the state. good afternoon. i'm kristen sze. thanks for joining us. governor newsom is in fresno to sign legislation aimed at protecting farm workers. the governor's office says the legislation will boost access to affordable housing to workers across the

state. newsom has been pushing for more support for farm workers after that 2023 mass shooting. at two mushroom farms in half moon bay led authorities to uncover just deplorable housing conditions. meantime, four other bills signed by the governor aim to toughen penalties for people involved in sideshows. sideshows are seen as a form of entertainment by some others, including law enforcement, view them as an illegal and dangerous nuisance. one of the new laws allows officers to remove cars that are blocking areas for sideshows, without having to also make an arrest. another law expands the ability to impound cars in sideshows that take place in parking lots, not just on highways. another expands the penalties for sideshows to include impounding cars for 30 days and requiring restitution for victims. the last law increases the penalties for both participants and organizers of sideshows that endanger children and cause property damage. now, speaking of sideshows, today,

san francisco board of supervisors will hold its first vote on a proposal to make it illegal to promote sideshows or set them up. mayor london breed wants the city to use drones, surveillance cameras and license plate readers to help catch the people involved. today, the cal fire firefighter arrested for a series of fires in the north bay is expected in court. the suspect is from healdsburg and was arrested last week on arson charges. he's accused of igniting five fires since mid-august in geyserville, healdsburg and windsor. investigators say the fires burned less than one acre combined. new developments in the shooting of forty-niners rookie ricky pearsall in san francisco's union square. the gun that the teen suspect allegedly used in the shooting was reportedly purchased legally in phoenix in february. according to the chronicle, a person bought the semi-automatic glock 23 from a store in downtown phoenix. the gun is popular among police officers. it's unclear how the weapon

crossed state lines into california and got to the bay area. the 17 year old boy accused of shooting pearsall is charged with attempted murder. currently, the da's office is pursuing the case in the juvenile justice system. mount diablo school district is getting ahead of a change that's likely to be difficult for students, educators and parents across the state. the phone free school act requires all california schools to come up with a plan by july 2026 to limit or ban cell phone use by students during school hours. supporters say limiting cell phone use in class will help improve students academic achievement and mental health. abc seven news reporter gloria rodriguez has more on the local district that's already started implementing restrictions. >> so student takes the bag, takes the phone, puts their phone in the bag. >> they closed mount diablo unified school district superintendent doctor adam clark shows me the pouches students use to lock away their cell phones during the school day,

and then at the end of the day, they run it through the demagnetizer. >> it unlocks it. they take their phone out and off they go. >> the pouches get unlocked at the end of the school day. students at the district's two continuation schools adopted cell phone limits since last year, and just this school year, mount diablo and ignacio valley high schools also did. superintendent clark says this has really cut down distractions for students in those schools. and he says a number of disciplinary incidents have also dropped. plus, they're finding other benefits. >> what we're finding at the schools that have implemented this during lunch time and passing period, kids are talking to one another. they're getting to know people. they're like, they got to sit down and talk when they have their cell phones, you'll see them. they'll be at a table and everyone will just have their face in the phones and no one's talking to each other. no one's doing things. and this just kind of takes that away. >> superintendent clark is applauding governor gavin newsom's move, signing a new law monday that california will have to create rules restricting student smartphone use to try to

minimize distractions in the classroom and address the mental health impacts of social media on children. >> bills like these are necessary to really bring the conversation home and give schools and districts the backing to start to make some of these tough decisions around the use of cell phones on campus. >> some parents have expressed concerns, but superintendent clark says those phone pouches can be unlocked in emergencies and that students can use their phones in special circumstances. in concord, gloria rodriguez, abc seven news all right, turning to the weather and another warm day to start autumn. >> a heat advisory remains in effect for most of the east bay, but if you want a cooler. let's call in for a little help here. spencer with the details. hey, spencer. >> okay, chris, in cooler weather is not far away. day number three of autumn, and it's still quite summerlike. we have a heat advisory in effect until 8:00 this evening for the east bay hills and the inland valleys

of the east bay. high temperatures in that area will range from mid 90s to about 100 today. and of course, with that kind of excessive heat, there is an increased risk of heat related illness, but relief is not far away. looking at satellite radar composite image, you see that the marine layer has already begun returning to the coastline. those clouds are only going to get deeper and thicker and expand during the overnight hours. and they've also they are also generating an an onshore breeze right now. we've got wind speeds right now at the surface at 15 to nearly 20mph near the coast, and the bay, and it will be even cooler as we get into the evening hours right now. check out the 24 hour change seven. well, five to 7 to 9 degrees cooler, generally across those areas you see on the map there than at this time yesterday. that's pretty impressive. so on we go. the view from sutro tower. looking out over san francisco, you see a little thin finger of fog pushing out over the bay. right now it's 67 degrees here in the city, 74 in oakland. we've got 86 at hayward, san jose, 9084 at redwood city, 60 one half moon bay. fog has returned to the

golden gate. it is 92 right now. up north at santa rosa, 88 at petaluma. napa 8398. fairfield 96. concord 101 at livermore. it's those inland areas are really hot right now, but they'll cool down over a lot over the next few hours as that fog starts to push across the bay. so these are the forecast headlines tomorrow. start with morning fog and a much cooler day tomorrow. then thursday through sunday. sunny days with minor warming here and there, but nothing like the heat we've had the last two days and the extended outlook calls for a more fall-like pattern, a more stable pattern going into next week. for tonight, look for the marine layer to expand and deepen and push locally across the bay, and they'll probably be some patchy drizzle just offshore and we won't see the fog burning back very quickly tomorrow morning because of course, it's not going to be as hot a day as we had today. overnight, low temperatures will be generally in the mid to upper seconds. much cooler than last night, but still pretty mild in places like livermore, fremont, palo alto, san jose and antioch, where lows will not drop below

60 degrees. tonight. they will. perhaps tomorrow night. tomorrow's highs 62. half moon bay 67. here in san francisco 70 at oakland up to mid 70s around many bay shore locations up in the north bay. we'll see. highs not quite at 80 degrees at santa rosa, 75 at napa. inland east bay tomorrow, low to mid 80s where today we had upper 90s to 100 and down in the south bay. look for highs of 80 at san jose and 83 at morgan hill. here's the accuweather seven day forecast. so a sharp cool down tomorrow. just bounce back a few degrees on thursday. up to about 90 inland and even more of a warm up on friday with mid 90s inland. but don't worry, we're not going into that triple digit territory again. it will start cooling it down again on saturday and then sunday and into monday we'll see a much more, more comfortable range of temperatures, certainly cooler and more autumn like. kristen. >> all right, spencer, thanks so much. still ahead, unexpected news from an nfl legend. brett favre says he's battling parkinson's disease. we'll talk with one of the authors of a new

study that shows favre likely has company, amongst other former players, and the maker of some popular weight loss drugs is being called out in washington. why some lawmakers insist ozempic and other meds don't really have

i've recently been diagnosed with parkinson's, favre told a congressional committee about his parkinson's diagnosis during testimony about a welfare fraud situation. >> the 54 year old played in the nfl for 20 years and has suffered multiple concussions. studies have found an association between concussions and traumatic brain injuries, along with parkinson's, which is

the second most common neurodegenerative disease after alzheimer's. the brett favre news comes a day after a new study showed 1 in 3 former nfl players believe they have the degenerative brain disease known as cte, linked to repeated hits to the head and concussions. many former players in the study reported having cte symptoms, such as suicidal thoughts. others reported a diagnosis of alzheimer's disease or other forms of dementia. joining us live now to flush that out more is the lead author of the study, which was published in the medical journal jama neurology. rachel grashow, director of epidemiological research initiatives at the football players health study at harvard university. doctor grashow, i assume. thank you so much for joining us today. >> yeah, thank you for having me on. >> so, given your research, do you see a potential link between brett favre parkinson's diagnosis and cte? >> well, i can't comment on brett's situation. our heart

goes out to his family for sure. we're looking at a different kind of condition, which is called chronic traumatic encephalopathy. and this is a condition that's been linked to head injury when players were, you know, when players were young and played. but that only can be diagnosed after they pass away, and so it's, it's a little bit different than what brett is dealing with, but i think the similarity is that we're talking about diseases that are seen as, sort of at the moment. there are no cures at the moment that are really helpful. they're difficult to diagnose, and in a lot of ways, i think people look for something to do when they get a diagnosis or have a concern like this. and i think we're asking questions about living players and how we can support them within the context of this potential condition. >> right. i mean, of course, you can't pinpoint cte, as you said, as the cause. right. because of the impossibility of biopsying the brain while someone is aliv. but if you look at, you know, the hits he took and the career he had spanning 20 years, and

then you look at muhammad ali, boxer, and many boxers also have degenerative brain disease. and, you know, muhammad ali had parkinson's. i mean, is there all a very strong link there? >> we can't say. i think that's what's been difficult for the science, is that there's been a lot that's been figured out about cte, which is a very real condition, but there's a lot that's still unknown. and i think the key to the study that we did that we published yesterday is really kind of looking at what do we know and what we don't know. and in some ways, what we cannot change is that these former players had head injuries. we can't do anything about that. and the thing that we also can't know is whether they're going to go on to be diagnosed with cte. as you said, you can only do that on an autopsy. and we think this puts players in a tough position because a lot of them, as they tell us both through the data and the surveys, and also when we speak to them, they're having cognitive symptoms, right? they're having symptoms of memory issues or planning or concentration or thinking. and so they're having those conditions and they want to be

proactive. but as you said at the moment, the narrative around cte is really that you won't ever know if you have it and that, and that there's nothing you can do about it. and actually, one of the key pieces of this study is that what we found was that what the guys had in common who believed they had cte, was that they had those cognitive symptoms. they told us that. but the key piece of our story that we really want to get out is that the guys who were worried about cte also told us they had a lot of conditions that caused cognitive problems. players suffer disproportionately from things like sleep apnea and hypertension, high blood pressure, high blood sugar, depression, low testosterone. and what we want to get the word out about is that those conditions are treatable. so while we can't do anything about the head injury, we really want to get the message to players that there's a lot they can do now to go after their cognitive symptoms, right? >> even without a formal diagnosis. right. you can have

targeted treatment for the symptoms that they're experiencing, can i just also dive in on one portion of your study that seemed to show that certain positions, made it riskier or perhaps had more association with some of those symptoms? >> yeah. i mean, i think that what we have to think about with position is that position carries a lot of things with it. right? it carries things like, head injury or orthopedic injury. it carries different exercise regimens and efforts to gain weight, cardiovascular exercise and training. so position really packs a big punch when it comes to changing the way a football player experiences football and then the health conditions they have later. and so you can imagine the guys that are bigger are more likely to have sleep apnea, which absolutely gets in the way of the way someone's brain functions the next day, you know, after a poor night of sleep, you can imagine that being heavier and having high blood pressure is a piece of the story as well, and so position, i don't think it's as simple as just the position. i think it's all the things that position

tells us about the playing experience. that comes down to pinpointing what players might have that we can go after with their doctor. >> all right. so if it's a lot to do with the playing experience, right, then i guess what is the takeaway? what can we do now to reduce the risk of all these players who are playing on the pro level? certainly. but maybe even college or youth, right. >> i think, well, i just want to be clear that you know, our study really is only looking at former players. so we don't actually work with active players. we're really about caring for them after they leave the league. and increasing the number of good years they have post-career, so when we think about that group, while we again can't go back and change their head injury and i can't speak to necessarily head injury in while they're playing or in college or youth, what i just want to emphasize, really, is that if we're caring for players after they leave, we can really encourage them to work with their physicians to go after what's treatable, because i think that's where there's a chance to kind of change their trajectory for brain health. you

know, while we wait for science to catch up and show us how to diagnose players and show us how to treat cte, i think we're really kind of trying to look under the light of the lamp post to say, how do we help players now? >> i see, i see, okay, but let me just ask you in that regard, right. it's not so much it sounds like from what you're saying, that. okay, you're done playing, the damage is done. you get what you get. you're saying there are actually active steps you can take that will make the long term outcome a lot better. >> that's exactly what we're saying. and a lot of ways there hasn't been a lot of research on this yet, but the question we're asking is if you treat what's treatable, even though someone had brain injury, what's their trajectory? you know, what will it be like to sort of treat their sleep apnea, high blood pressure, high blood sugar, i think that's what we're going after. there's a lot of doom and gloom and hopelessness in, you know, the way that we talk about cte right now and again, while we wait for science to catch up with what we need to know, and so, you know, and we saw this in a sense, you know, that there's a lot of hopelessness that we

think goes on with this, we believe that former players, we saw that former players who think they have cte were five times more likely to tell us that they had thoughts of self-harm and suicide. and so we're hoping that physicians who are listening will take this seriously. and maybe initiate those conversations with players to ask if they have those worries. yeah, to check them for those conditions. i think that's what we're hoping for here. right. >> it almost doesn't matter what the formal diagnosis will be one day. it is what you have right now that you're dealing with. right, do you think from your survey, did you find that there were a lot of players who suffered in silence, so to spea? >> absolutely, we think that so many of the players told us that they had depression. and just like in the regular world, depression is the biggest risk factor for suicidality and thoughts of self-harm. so we absolutely see that. but i think, again, i know i keep saying it, but depression is treatable between therapeutics, medicine, exercise, diet. there's so many things that can be done for the conditions that they told us they had and really were suffering with the symptoms

of those conditions. and what people forget to people don't think about is that the body and the brain are very tied up together. so if the hormones aren't right, if the heart isn't working well, if there's pain, i think all of those things can get in the way of brain function. and we want to make sure that players don't prematurely attribute some of those symptoms that may be associated with that maybe come from head injury to a condition that's not treatable right now, i think it will come, but it's not here yet. >> doctor rachel grashow, who is at the football players health study at harvard. thank you so much. really appreciate your time. >> thanks. so much. it was great to be here. >> still ahead, do weight loss drugs really have to be expensive? some lawmakers say no and they're demanding to know why one company is charging so much. the testi

an attempted assassination charge against the man accused of staking out former president

donald trump at one of his florida golf courses. prosecutors say ryan ruth had written a note detailing his plans to kill trump. the note was found in his car and included a list of dates and venues where trump was set to appear. during a hearing yesterday, ruth was determined to be a flight risk in order to remain in custody without bail. today, in washington, d.c, lawmakers grilled the ceo of the company that makes ozempic and wegovy over the price of those drugs. abc's tim pulliam has more on the testimony on capitol hill. >> treat the american people the same way that you treat people all over the world. stop ripping us off. >> armed with charts, facts and figures, senator bernie sanders wanted answers. >> you are charging the american people substantially more for the same exact drug than you are charging people in other countries. and my question is why? >> novo nordisk charges

americans with type two diabetes $969 per month for ozempic, compared to other countries like canada and germany, pay far less. americans struggling with obesity pay even more for wegovy $1,300 a month. sanders says the company has made $50 billion from the drugs. >> we are very committed to make sure that americans have access at an affordable price point for our medicines. >> the company also says the high costs go toward developing and manufacturing the drug. >> we launched ozempic in 2018 and we have had it on the market for some years. during those years, our price has declined by 40%. >> ultimately, lars jorgensen blamed the u.s. health care system. >> it is a very complex market and very complex health care system that creates a lot of misunderstandings. >> the novo nordisk ceo blaming pharmacy benefit managers and industry. he says, can hike the

cost of drugs even when the company tries to make it affordable. tim pulliam, abc news, los angeles. >> at the end for the a's at the oakland coliseum, we're just a couple hours away from the first pitch of the last home stand. what the team is offering fans this week as a go

i'm three days in a row saying goodbye to the city. they've called home for the better part of a century. here's a live look at the coliseum for you. still quiet at the moment, but the coliseum property that is from our camera along interstate 880. the fans attending the final three games there will be sent

home with a few souvenirs. abc seven's amanda del castillo has more on what's sure to be a bittersweet sendoff. >> the fans at the final three games at the oakland coliseum will not just have memories of the end of an era. they'll have a little bit of stuff, too. for every game this week, tuesday night, wednesday night and thursday afternoon, oakland a's fans will get a special final series commemorative ticket. then thursday, the last game at the coliseum, the first 25,000 fans will get a replica of the oakland coliseum. it is a sold out game, so this means a little more than half of the ticketed fans will get one of those replicas. this whole thing has been a little controversial. the fans won't actually receive the giveaway item until they leave, so some people were speculating there was a ploy to get people to leave early. but it turns out that first 25,000 fans, they'll actually get a voucher when they go in to trade in for the swag

when they leave. still, the hashtag stay in your seat is trending among fan groups. they just don't trust team officials anymore. the groups are encouraging diehard oakland a's fans to stay at the coliseum as long as possible for that final game. i'm amanda del castillo. let's play ball. >> and we're going to play here. women's professional soccer is coming to san francisco's treasure island this morning. bay fc and mayor london breed announced plans to build an eight and a half acre training facility on the island. it will include a 20,000 square foot clubhouse and three practice fields. bay fc wants to break ground on the privately financed project next year and begin practicing there during its 2027 season. >> this is so incredible to see women's sports take it to the next level and to see people get so excited. this is not necessarily where legends are born. this is where legends will be made. >> the long term lease must be

approved by the treasure island development authority and the san francisco board of supervisors. that's going to do it for now. thank you so much for joining us. world news tonight with david muir starts right now. and i'll see you back here at four. tonight, breaking news as we come on the air. the u.s. braces for a potential category 3 hurricane. the states of emergency already. also breaking tonight, the emergency response under way right now. a toxic leak, thousands evacuating. there is concern at this hour over a potential explosion. and former football star brett favre revealing a stunning diagnosis tonight. first this evening, tropical storm helene gaining strength as it closes in on florida. hurricane warnings and watches in place toni
