within the republican party, only two went on to become president. george w. bush and donald trump. so iowa is not the end-all be-all, is it? >> reporter: that's exactly right. this is just the beginning. and nikki haley especially is looking to new hampshire as a place where she comes out of iowa with a pretty strong showing, she can maybe even get an upset there. and some of the biggest republican donors in the country tell me behind the scenes that they're ready to pour millions behind her candidacy if she starts to show some momentum. jericka? >> all right. robert costa covering it all for us. thank you. tonight israeli prime minister benjamin netanyahu struck a defiant tone marking 100 days of war against hamas in gaza. he vowed to keep fighting despite growing uncertainty about the outcome and international alarm about the rising death toll. today thousands rallied in tel aviv, demanding the government do more to bring home those hostages still held by hamas, believed to be at around 105

hostages. as for civilians in gaza, war has been catastrophic for the territory. cbs's charlie d'agata has the latest. charlie? >> reporter: good evening, jericka. it is a grim milestone for everyone here. 24-hour vigils, those demonstrations across israel in remembrance of those victims of the massacre, fears over the fate of hostages still missing, and the ongoing tragedy of the soaring death toll inside gaza itself. fresh israeli assaults today marked day 100 since the war began with no sign of when or even how it may end. it no longer matters for the dead arriving among those still clinging to life at the al aqsa hospital in central gaza today, adding to a death toll nearing 24,000 people. while hundreds of thousands of the displaced wonder how much more they must endure.

our cbs news colleague in gaza, marwan al ghoul, a survivor himself, covered this wedding only a couple of days ago at a shelter in rafah. a rare glimpse of joy, a moment of hope amid the misery. yet he reported this too. the chaotic scenes at a bread line as residents jostled for food. aid agencies say it's too dangerous to get food to those who need it most. at the kerem shalom crossing into gaza we put that claim to the israeli military. >> we are also conducting large-scale humanitarian operations every day. inside the battlefield. >> inside the battlefield. >> inside the battlefield. >> reporter: but that's in direct contrast to what aid agencies on the ground are saying inside gaza. the u.n. has warned that a quarter of the population is now on the brink of starvation. while in israel today people across the country took part in events to mark the day, including tel aviv, where

thousands held a 100-second moment of silence. not only to remember more than 1,200 people murdered on that saturday morning but not to forget more than 130 hostages who remain missing. and there are worrying claims tonight from a spokesman for the armed wing of hamas, jericka, who said most likely many of the hostages have been killed recently. that the israeli leadership and military bear the blame and the rest of the hostages remain in grave danger. >> charlie d'agata, thank you. >> charlie d'agata, thank you. and we're done.

the first votes of the 2024 presidential campaign come tonight in the iowa caucuses. and between the frigid weather and donald trump's big lead over his opponents, turnout may be light. trump hasn't spent much time in iowa, instead focusing on his legal issues. robert costa reports. >> ketchup and mustard? >> okay. >> thank you so much. >> reporter: the iowa caucuses are tomorrow, so you may wonder why i'm here in lower manhattan. it's because this year the presidential campaign trail runs through courthouses like this one. in washington this past week attorneys for former presidet trump argued in federal court that an ex-president should be immune from prosecution. arguments that seemed to get little love from the judges. >> i feel that as a president you have to have immunity. very simple. >> reporter: a ruling could come in days. though it could be appealed to the supreme court. hinging on that decision is the justice department's case

against trump for attempting to overturn the 2020 election. also on the docket, a federal trial for mishandling classified records. georgia state charges of state election interference. and in new york a defamation suit, plus trials over hush money payments to a porn star as well as real estate fraud. >> what percentage of your time these days is spent on your campaign and what percentage is spent on your legal issues? >> well, see, my legal issues, every one of them, every one, civil, and the criminal ones, are all set up by joe biden. crooked joe biden. they're doing it for election interference. and in a way i guess you'd consider it part of the campaign. >> reporter: trump blaming his legal woes on conspiracy theories is just further evidence that they are more than a sideshow. they are a reckoning. about what a trump return to the white house would say about the country. while iowans caucus tomorrow the

nation will also pay respect to the legacy of dr. martin luther king jr. yet trump's incendiary rhetoric on race, immigration and on political revenge has only helped cement his lead in polls with republicans. as iowa plunges into arctic weather, florida governor ron desantis hopes to dent trump's lead while also battling former trump ambassador nikki haley. haley has her sights set on new hampshire later this month, hoping to benefit from chris christie's departure from the race. trump allies tell me that this courthouse where his businesses have been in the spotlight in a civil fraud trial is now his center of the political universe, a place the candidate believes fuels his grievances and those of his supporters, and all of these court appearances underscore the stakes for trump and the nation. >> that again was robert costa reporting. one issue dividing the republican candidates is ukraine. right now u.s. aid to that

country is stalled in congress, and that's got the ukrainian army trying to adapt. chris livesay has more. >> reporter: russia's arsenal has gotten a massive infusion of munitions and other weapons from iran and north korea. this as ukraine's own stockpile of weapons is dwindling and as u.s. aid is running out. at a secret location in the cover of night engineers fire up the booster of a makeshift cruise missile. do-it-yourself weaponry that civilian inventors say can strike russian targets more than 100 miles away. >> so it's a very lightweight, easy to assemble, and a key feature, extremely cheap, between two and ten thousand dollars to produce compared to 10 to 100 thousand dollars if they were to buy it retail. desperate bargains uk vane now forced to make as u.s. funding dries up. since russia's full-scale invasion nearly two years ago

the u.s. has provided more than $40 billion in military aid to ukraine. used to astonishing effect, repelling one of the largest armies in the world. but in recent months ukraine has been struggling thanks in part to russia's deep supply of munitions from north korea and attack drones from iran. it's a life or death fight that kyiv mayor vitaly klitschko, a former world heavyweight champion, like toenz a punishing boxing match. >> my background is sport. it's condition, endurance beat always the power. and right now we need to have endurance. we need to be strong in this long, long war. >> reporter: a long war that's killing ukrainian civilians every day, says ukrainian lawmaker oleksandra ustenova.

can ukraine make it without u.s. military aid? >> president zelenskyy was very clear when he said it to president biden, if there is no support coming from the united states we're done. >> reporter: if ukraine falls that puts russia firmly at nato's doorstep, where the treaty demands that an attack on one is an attack on all. >> which means that the united states would have to step in the war. and it would not mean less than 1% of the budget. that would mean trillions of dollars and boots on the ground. >> reporter: a point not lost on displaced ukrainians like larissa and her son mark, who lived for eight months under russian occupation. "if americans don't pay with their tax dollars for ukraine to fight against the russian invasion," she says, "they will eventually have to pay with their lives like we are." this week a pentagon report blamed u.s. officials for not tracking aid to ukraine closely enough. but the same report said ukrainian officials at least in some cases did a better job of tracking that military aid than the americans did.

nevertheless, this places yet another hurdle on ukraine just as time and bullets are running out. out. chris livesay, this is a hot flash. this is a hot flash. but this is a not flash. ♪ i got a good feeling ♪ there's big news for women going through menopause. veozah - a prescription treatment for moderate to severe vasomotor symptoms - the medical name for hot flashes and night sweats. with hormone-free veozah, you can have fewer hot flashes, and more not flashes. veozah is proven to reduce the number and severity of hot flashes, day and night. for some women, it can start working in as early as one week. don't use veozah if you have cirrhosis, severe kidney problems, kidney failure, or take cyp1a2 inhibitors. increased liver blood test values may occur. your doctor will check them before and during treatment. most common side effects include stomach pain, diarrhea, difficulty sleeping,

and the privacy thing too. that was a surprise to me. it's totally quiet. >> so there's no flush. >> there's no flush. >> reporter: that's because lissa schneckenberger uses a very special toilet with two compartments. >> toilet paper and solid waste go in the back, and then urine goes in the front. so there's two compartments. both go into separate compartments downstairs in these collection talks. rich earth comes with a big truck and a big hose and they empty the urine tank twice a year. >> how much urine have you saved? >> it's a lot. >> reporter: and if you don't happen to have a special toilet, the rusch earth institute offers this low-tech portable urinal. >> now, would only a man use this? >> no. men can use it, but women can also squat over this. >> reporter: rich earth also makes it easy for donors to deliver their liquid waste to a downtown depot. as you can see, the process requires no pouring. >> i think it's pretty great. >> reporter: kevin o'brien is a

community tool librarian who's been bringing his urine here for three years. >> for me it takes me about a month to fill up a five-gallon jug. so i kind of come to the depot about once a month to donate, although i want to reach toward a goal of donating 100 gallons a year. >> reporter: those who do receive a lovely certificate from rich earth. >> so the urine comes in, goes through this system. >> reporter: urine is typically free of harmful bacteria, but if it gets near solid waste that could lead to disease. so abe noe hayes says that all of the urine that rich earth collects is pastureized to federal standards. >> it's clean? >> yeah. it's heated up. the pathogens die. it cools back down. and then it leaves the machine. >> reporter: and then arthur davis transfers the clean urine from the huge storage tanks to his truck's containers. around 1,000 gallons at a time. >> it's actually about four tons. >> reporter: on his big yellow

truck, with the custom license plate, davis oversees the entire collection and distribution process. >> we're dealing with chemistry. we're dealing with biology. we're also dealing with psychology of people because people have all kinds of thoughts about it. ready for you. >> reporter: today he's delivering to a true believer. noah hoskins, owner of the bunker farm. hoskins says his grazing fields are thursday for pee. >> if you are taking nutrients out of the ground, you need to be replenishing those nutrients in some form or another. >> reporter: a lot of peecycling is still in the research and development phase. >> ph of 4.66. >> reporter: but came nace and abe noe hayes imagine a bright yellow future. you're kind of asking for a cultural change. >> we're not asking people to do something that's difficult. you just use the toilet. that thing you just did, that was great. you know, you made something

done. >> reporter: if ukraine falls, that puts russia firmly at nato's doorstep, where the treaty demands that an attack on one is an attack on all. >> which means the united states would have to step in the war. and it would not mean less than 1% of the budget. that would mean trillions of dollars and your boots on the ground. >> reporter: a point not lost on displaced ukrainians like larissa and her son mark who lived for eight months under russian occupation.

unique system of choosing a presidential candidate work? cbs's ed o'keefe explains the process. >> reporter: it's time for iowa to make up its mind. >> i hope people pay attention and go out and caucus. it's extremely important. >> if you don't know there's a caucus coming up in iowa, you're living under a rock. >> reporter: unlike a primary when polls are open for several hours or states that allow absentee ballots, the iowa republican caucus requires mandatory in-person attendance, 7:00 p.m. monday night. there are about 1600 individual caucuses held statewide. only registered republicans can participate. >> the only candidate who can beat joe biden -- >> reporter: first up, someone speaks on behalf of each candidate. then votes are cast on secret paper ballots. >> one, two, three -- >> reporter: and counted in front of the crowd before final results are reported to the state party. >> nikki haley had three. >> anyone caucus last time? >> reporter: in mason city they're trying to avoid issues on caucus night by rehearsing. julie billings walked 40 fellow republicans through a mock caucus last week. >> guys, order. >> reporter: one going is to ensure the number of votes cast matches the number of people in the room. >> do you trust this process? >> yes. >> there's checks and balances in place. paper ballots are hands down the best way to go. >> watch what happens. you be the eyes of the person counting. there's accountability there. >> reporter: just 186,000 people participated in the last competitive gop caucus in 2016.
