>> both mayor march scone any and supervisor harvey milk have been shot and killed. >> reporter: many have pointed to this moment as the start of a political journey that would span nearly half a century. dianne feinstein herself says that moment was the most painful and difficult thing she has ever had to go through. years later, her colleagues still remember her incredible strength, not just in that moment, but in her decade as san francisco mayor. former san francisco mayor art agnos says her list of contributions to the city are long. >> she took control of the aids crisis, brought us through that. she brought us through the awful period, as i said earlier, of the time when the mayor was assassinated along with supervisor milk. when the city could have gone off kilter and struggled, it did not because of her strong leadership. >> reporter: in an earlier interview, former san francisco mayor willy brown reflected on feinstein's strong leadership. >> dianne was obviously the key to keeping the city sane, so to speak. her demeanor and her conduct was just impeccable. >> today with the 89-year-old announcing she will not seek re-election in 2024, leaders from across the state are beginning to reflect on her career and contributions. mayor london breed calls feinstein a trailblazer adding her landmark policy victories in the senate like the assault weapons ban, the repeal of the defense of marriage act and reckoning with our country's past with unlawful interrogation tactics, made our country safer, our society more equal and our nation more true to its ideals. art agnos recalls key issues she faced head-on. >> she's always been strong with the environment, with assault weapons in the united states senate. she actually passed a bill that is almost iconic now because it's been so difficult to do anything since she first passed the bill. >> governor newsom credits feinsteins for changing laws across the nation and opening doors for generations of female leaders. in san francisco, marianne favro, nbc bay area news. >> senator feinstein's long and store read career of public service will obviously always be tied to san francisco as you just heard. in a previous interview with us in 2015, she talked about the moment when she had to bring the constituent together following the as seas nation of mayor moscone and harvey milk. she said the effort was boosted by an unlikely source, the 49ers. >> the city was very divided. there was palpable hate. my job was to put the bricks back together again, and my job was to put a kind of feeling back in the city. we've always been a diverse city and always managed to get along together. this is where the 49ers came in and the first super bowl. and winning that super bowl and what it did for san francisco, to bring people together, it was such an exciting time. people came together and old wounds were forgotten. >> president biden released a statement a couple hours ago which read in part, quote, i've served with more u.s. senators than just about anyone. i can honestly say that dianne feinstein with one of the very best. i look forward to continuing to work with her as she serves out her term. our coverage of the senator's announcement continues at 6:00. we'll look at the list of candidates looking to fill her seat. the motive still unknown. police are trying to understand why a 43-year-old man targeted students at michigan state university. the gunman killed three and critically wounded two others at two locations. the three students killed were in their sophomore and junior years. police say the 43-year-old gunman wasn't a student there and didn't have ob yois ties to michigan state. >> three or four really -- i could hear gunshots directly behind my head, and i could see the smoke from gunpowder or something from the weapon firing, and then immediately i dropped to the floor. >> she said students in the back of the classroom helped the wounded as others broke up a window and helped survivors escape. after a short manhunt police found the 43-year-old gunman dead of what is believed to be a self-inflicted gunshot wound. today students are leaving flowers and a rock painted with the message "how many more." we're taking a closer look at how local colleges are handling campus safety in this current clief. nbc bay area pete cerrato has more. >> reporter: the contra costa community college district is home to more than 50,000 students across five tam puss. for many of them, growing up in this era, mass shootings have become a common reality. >> especially my generation, i think a lot of kids kind of live in danger. >> as a student i'm concerned for my safety at my campus. >> we have a lot of empathy for the folks at michigan state university. >> reporter: jim leone is the director of communications for the district and says the current state of mass shooting including the most recent at michigan state university means campus safety is one of the district's top priority. the colleges partner with local law enforcement for active shooter training exercises to help familiarize agencies with the layout of campuses should an active shooting take place. >> they walk the streets, they walk the hallways, long our campuses and they have such greater intimate knowledge about the physical plant that makes up any of our campuses. >> reporter: there's also emails and text alerts to students and staff in the event of an emergency. inside every classroom, this emergency button can be pressed to alert campus security during an active shooter situation. >> it has lights. it has a digital readout as well as a button that can be pressed in case a situation is occurring. >> reporter: in his 16 years with the district, tim says there haven't been any major active shooter situations on their campuses, but that won't change the district's approach when it comes to campus safety. >> that's not to say that we're going to take it lightly and we're not going to be as prepared. >> reporter: in contra costa county, pete suratos, nbc bay area news. >> check out nbcbayarea.com for the latest information on the shooter's possible motive. police will again be walking city streets to address crime concerns. today mayor sheng thao announced plans to bring back officer foot patrols. the foot unit was put on hiatus two years ago. now with more staffing and grant funding, six officers and a sergeant will go back to patrolling on foot starting next week. the mayor says it's one step in a much larger effort to make the city safer. >> this is not a new problem. we know that. but it is a challenge and i know we can rise to meet it and come together. this is what it's about. it's about bridging those gaps with not only government, but with businesses, with residents, with visitors. >> now, the opd is also working to increase presence around the airport, an area that's been a target for car break-ins. the mayor says other efforts include a d.o.t. vehicle enforcement that will remove abandoned cars throughout the city, and the unit will free up opd resources. more help and funding is under way for victims of last month's shooting in half moon bay t. board of supervisors approved a resolution for $750,000 for emergency housing for the farmworkers displaced by the shooting. a lot of workers lived at the mushroom farms where a man shot and killed seven co-workers. the vote allows the county to use altogether $1.5 million to provide housing and support for those victims through march of next year. $750,000 comes from the american rescue act. the rest is from outside donations. >> the mass shooting put a spotlight on the living conditions we've seen at these two farms. they were living in unsafe and substandard conditions, and the residences have been red-tagged. they are now homeless because of this tragedy. >> yesterday the county also launched a task force to help all farmworkers who live in housing provided by their employer to avoid the horrible conditions farmworkers were living in at the farms in half moon bay. hearts certainly have a special meaning on valentine's day, but for one man, eddie garcia, suffered a heart attack 13 years ago. he's alive today because someone give him the ultimate gift, a new heart. damion trujillo looks at how he's paying it forward. >> reporter: these days you can find eddie garcia walking in his usual four miles per day and soaking in everything and everyone around him. eddie remembers a day in 2010 when everything went dark. >> i was on top of the world. everything was going great, life was great. from one second to the next, my whole life had just collapsed. it was a scary, scary night. >> reporter: at 46 years old, eddie suffered a massive heart attack. his case is not unusual. the most recent study by the american heart association shows more than 52% of latino males in the u.s. suffer from heart disease, a silent killer, and the attack left eddie desperately in need of a new heart. today he's walking with the heart of a man he never knew from a family he's never met. >> i have their son's -- i know it's a man, their son's heart in my chest, but it's my heart. >> reporter: since then eddie vowed to take care of that man's heart, and everything was going well until a day when his doctor called with very troubling news. >> my doctor called, and she says, eddie, you need to come into the hospital like right now. what? right now. we've detected heart rejection. >> reporter: a new blood test by a peninsula company called care dx allowed doctors to see that something wasn't right, something that previously required a far more invasive test. >> in the blood, we can see if there's shedding in the blood. if we see shedding in the blood of the organ, we know there's organ injury. >> reporter: the test meant eddie got the early treatment he needed and now walks with no issues, exercising his heart. these days eddie is also an organ donor advocate, giving speeches, even writing a book titled "summer in the waiting room," telling his story of survival. >> i want to do what i can to use my story to let people know they have to take care of their heart because it's worth it. >> reporter: eddie is making the most of his second chance at life, living each day to the fullest, one beat at a time. damian trujillo, nbc bay area news. still to come, two south bay schools are facing closure, leaving some parents and teachers upset. their last-ditch effort to keep the campus open. after originally stumbling across the issue, a bay area woman has spent the past three decades trying to preserve wetlands. the way she's bringing in new people to help join her fight. i'm chief meteorologist jeff ranieri, a windy, very blustery day out there, up to 46 miles in ocean beach, santa rosa, 35. we'll talk about the wind and the cold night and some staggering numbers when we take a look over a charter school is closing and parents and teachers are struggling to understand why. it will impact about 650 middle and high school students. in a statement summit said it's due to financial issues. some parents are protesting this decision. they say it's too much of a disruption for their kids as well as their families. teachers now have three months to find a new job. the teachers union says summit is not being transparent with them. the county office of education board will discuss the closure at a meeting tomorrow. when you think about northern california's natural beauty, we often think about the forests, the mountains, the beaches. wetlands probably doesn't come first to mind. >> no, but to one north bay woman they are beautiful, they are valuable and they are worth saving. garvin thomas has her story in tonight's "bay area proud." >> did you know every year millions, yes, millions of birds my great to the bay area. maybe you did. did you know there's one woman who dedicated her life to making sure that continues to happen. just who or what gets credit for creating the beauty that is san pablo bay is a debate left for theologians and scientists. protecting one corner of it for the past 30 years, there's no question. although myrna hayes says looking back, it was a calling. >> i knew nothing about wetlands. i don't know that i knew the word. i wasn't interested in birds. >> we have the auction closing in five minutes. >> reporter: myrna just hosted for the 28th year the san francisco flyaway festival. it is, on the face of it, a gathering for birders. but mir nah's real goal as always is simply to draw people, any people to the edge of the bay and watch them fall in love. >> the wetlands definitely do not wow you like yosemite. they are much more the seeping through your skin into your bloodstream. they really have to just be there -- >> good morning from the reserve. >> reporter: just being there is how her activism started all those years ago, her neighbors drafting her to help oppose a nearby development. the more time mir nah spent along the bay shore, the more she wanted to protect it. she says once it is gone, there's no getting it back. >> that is my drive. that's what makes me up in the middle of the night, keeps me awake long periods of time. okay. i'm myrna hayes, i don't know all of you, but some of you have been with me forever, right? >> reporter: it's what's fueled myrna for all these years even though she's lost as many press ser investigation battles as she's won and not always made friends along the way particularly with politicians who didn't share her vision for preservation. still, she keeps moving, always with the goal of keeping the wilderness in her corner of the world just a little more wild. as i mentioned, myrna has both won and lost battles of preservation, in one case over the same piece of land. in 2009 she and her group opened up more than 100 acres of the former naval base on the island to the public, only a decade later to have it taken away. she has over 10,000 signatures to reverse that decision. >> jeff joins us now. it is galentine's day. >> celebrating gals. >> we are looking at chilly weather continuing out there tonight and into tomorrow. with all these cold weather, we wanted to take a look back at exactly how cold we have been. no, it is not my imagination or yours. we have been under some brutal chill the past couple of months. look at this data here. napa, our low temperature since october 1st, 2022, temperatures in the 30s or lower, we have had 70 nights dipping into the 30s or lower. that accounts for 51% of our evenings. isolated 12 freeze warnings, december 18th. over all the coldest weather since 2014. so here we go again. more of that coming our way as we roll through tomorrow. i know the gas bills and the electric, they have been sky high. the thing that's really driving this latest round of chilly weather is this area of high pressure right here. the way it's setting up through tomorrow, circulation around it is going to bring down more of that chilly air and also keep a little wind in that forecast. let's get to the wind first. then we'll get to exactly how low i'd going to go with the windchills tomorrow morning. i see things trying to diminish a little for tomorrow morning at 7:00, but still seeing gusts of 20-40 in the bay. 31 in napa. 13? san jose. a lot less blustery by tomorrow afternoon and evening. winds at 15 miles per hour and less for most of the bay area. with a little bit of the wind still hanging on for tomorrow morning, hold on, check this out. windchills that are going to make it feel like 26 in san jose, 25 in livermore, 30 in fairfield, also 30 in napa and 29 in santa rosa, even feeling like 35 in san francisco as the wind kicks up. make sure to have the heavier jacket. layer it up to keep yourself warmer as you roll through tomorrow. meanwhile, as we roll through the day, i see numbers going a little higher with less wind in the afternoon and sunshine. 60 in santa rosa. 57 in livermore, also 59 right here in san jose. beyond this we'll get cloud cover back as we roll into thursday's forecast. the storm system is offshore. this thing looks impressive, but most of this is going to be moving off towards the south. you can see it right there. only looking at a spotty chance of a shower as we hit friday's forecast. we'll dry out and warm it up. san francisco in the low 60s. as we roll through next week, so far, no storms into monday and tuesday. inland valleys, there we go, 64 on saturday, 66 on sunday. by the end of next week we could certainly see increasing rain chances. that would be great. galentine's day. i get it. production is set to resume in the filming of a move i have that led to the death of a
