before, but not this low. we are not loading the barges as heavy so we have to make more trips. so you have more boats down there taking fewer barges doing more laps. ♪ >> major funding for the "pbs news weekend" has been provided by -- >> this is a pocket dial. i thought i would let you know with consumer cellular you get nationwide coverage with no contract. it is kind of our thing. have a nice day. ♪ >> and with the ongoing support of these individuals and institutions. and friends of the newshour. ♪

this program was made possible by the corporation for public broadcasting, and by contributions to your pbs station from viewers like you. thank you. john: good evening. i'm john yang. with conditions at gaza hospitals getting worse, israeli prime mister benjamin netanyahu said today that any ceasefire agreement would have to include the release of all the israelis hamas is holding in gaza. netanyahu also said that pressure from israeli ground operations pushed hamas to negotiate about the hostages. but there are reports tonight that hamas has paused the talks because of the ongoing chaos around gaza's hospitals, which is what special correspondent leila molana-allen begin her report with tonight. and we should warn you that some

images may be disturbing. >> hospitals across gaza are on the brink of collapse. doctors have been working by flashlight to treat patients. staff were unable to continue treating under the conditions and were forced to stop accepting new patients. >> sorrow pain, anger,

, discontent, and disappointment, these are our feelings today after we had to announce al-quds hospital in gaza city is out of service, after a whole week of calling on the international community to let aid come in urgently. reporter: al shifa hospital -- the biggest in gaza -- was also forced to close to any more patients today. premature babies were lined up in ordinary beds because there was no more electricity to keep them on their life-saving incubators. >> we are nearly sure that we are alone now, no one hears us. we want someone to give us the guarantee that they can evacuate the patients. reporter: today on nbc's meet the press, israeli prime minister binyamin netanyahu claimed last night israel offered to provide enough fuel for the hospital to use and militants refused it. >> we have obviously no battle with patients or with civilians at all. and i think every civilian death, every dead baby is a tragedy. reporter: hamas denies refusing any amount of fuel from israel intended for medical use at gaza's al shifa hospital. in khan younis, in southern gaza, the israeli bombardment continued. a gaping crater obliterated houses and buildings, killing at least 13 palestinians. residents combed through the

rubble looking for any survivors. in an interview on cnn's fareed zakaria gps, un secretary-general antónio guterres had this to say on the ongoing bombings. >> you cannot use the horrific things that hamas did as a reason for collective punishment of the palestinian people. reporter: on the hostage negotiation front: there was word today from a palestinian official that hamas has suspended negotiations with israel because of the way it handled attacks on the al shifa hospital. and as more people try to leave gaza, the rafah boer crossing to egypt reopened after a two day closure. many of those allowed to cross today were russian. and as the war threatens to trigger a wider conflict in the region, on israel's northern border with lebanon the sky was thick with smoke from rocket fire between the lebanese militant group hezbollah and israeli forces. for pbs news weekend, i'm leila molana-allen in tel aviv. john: newly minted house speaker mike johnson is facing opposition from some members of his own party to his plan to avert a government shutdown at the end of the week. some hard-line conrvatives say they'd vote no on it because it doesn't have any spending cuts. the white house called the plan unserious. johnson's plan would fund parts of the government until january and other parts until february. it does not include money for israel, ukraine, or the u.s.

southern border. the pentagon says 5 army special opations forces were killed early saturday morning when their helicopter crashed into the eastern mediterranean sea. they were carrying out a routine air refueling mission as part of training. at the beginning of the war in israele pentagon sent additional forces to the region. russian forces are ramping up attacks in two eastern ukrainian cities. russian battalions are trying to encircle avdiivka, a ukrainian stronghold considered the gateway to parts of the ukrainian-held eastern donetsk region. and, in bakhmut to the north, the site of the war's bloodiest battle, russian is trying to take back ukraine's incremental gains from its summer counteroffensive. and it was not quite the storybook ending to megan rapinoe's storied soccer career that some had hoped for. last night was her final game, and it was for the national women's soccer league championship. she was in the starting line-up for o.l. reign, but less than 3 minutes in, she limped off the field with a suspected torn achilles tendon.

her team lost the match 2-1 to gotham football club, giving gotham their first ever title, a remarkable turnaround for a team that finished in last place last season. still to come on pbs ns weekend, with the mississippi river at historic lows, how it's affecting farmers, consumers, and international trade. and, for native american heritage month, the story of a trailblazing astronaut, john herrington. >> this is pbs news weekend from weta studios in washington, home of the pbs newshour week nights and weekends on pbs. john: the federally funded president's emergency plan for aids relief, or pepfar, provides hiv prevention, treatment and education around the world. it's the biggest commitment of any nation to fight a single disease. it's estimated to have saved 25 million lives since president george w bush launched it in 2003.

throughout its existence, pepfar has enjoyed broad bipartisan support on capitol hill. that is, until this year. a small group of conservative house republans is blocking legislation to reauthorize pepfar. they say the biden administration is using it to promote abortion overseas. supporters say there is no evidence to back that up. in september, president bush wrote an op-ed in the washington post urging congress to reauthorize the program. he wrote, "there is no program more pro-life than one that has saved more than 25 million lives." jennifer kates is senior vice president and director of global health and hiv policy at kff. jennifer, let's start with the basics. what does pepfar do and where does it do it? jennifer kates: so pepfar is the global aids response of the u.s. government is a very large it's the largest program in global health that the u.s. has and one of the largest in the world. and provides funding support to many countries around the world, about 50, to launch and deliver hiv services, whether that's antiretroviral treatment,

prevention, social support, education, working with countries, working with partners on the ground. and it's widely known as one of the most successful programs in the world. as you said, saving 25 million lives. and our analyzes have also showed that it's had even broader impacts beyond hiv. john: what are the things about it that has made it so successful and so effective? jennifer kates: when it was launched, it was launched, you know, with a lot of incredible bipartisan support. and having that bipartisan support has really lent the program the kind of support and ongoing stability that it's needed. in addition, the program has been funded pretty well with by congress. and also one of the unique things about it is it's been very focused on data and metrics . so it has actually made changes over time when its new treatments have come on board, when it's seen that it needs to focus on a different area.

so it's very driven by the science, driven by the data, and a very large commitment that involves multiple agencies across the u.s. government. john: you say it's gone beyond hiv and aids. during the covid pandemic, did it use some of its organization and infrastructure to do to work on that? jennifer kates: so during covid, when essentially the world shut down, the operations in countries where pepfar has also had to shut down for, for a large part. what pepfar was able to do, though, they were able to use that infrastructure to respond to covid. because the infrastructure is there, the u.s. has already developed it in many, many countries. and it was an incredible example of taking something thathere the investment was hiv specific and being able to build on that. john: the opposition to reauthorizing pepfar on capitol hill is being led by representative chris smith of new jersey, long time ardent foe of abortion. he's now chairman of the house foreign affairs subcommittee that has jurisdiction over pepfar, and listen to how he defends or explains his

opposition. chris smith: i strongly supported pepfar when it was created in 2003 and i was the sponsor of the ruthorization of it in 2018. regrettably, it has been reimagined, hijacked by the biden administration to empower pro-abortion international ngos deviating from its life affirming work. john: what do you say to that? jennifer kates yes so -- jennifer kates: yes so representative smith mentioned that he was a supporter or has been a supporter of how far he really has been. and the program has been reauthorized three times. this would be its fourth. i think what has happened is the larger politics in the united states around abortion and the partisan differences between republicans and democrats have sort of taken over what has been a very bipartisan discussion. i think the important piece to know, though, is there's several u.s. laws that actually restrict the use of u.s. funding for abortion.

pepfar doesn't fund abortion. it never has. there's no evidence that it has. this is really a broader issue around differences between the current administration's views on abortion and choice and that of those who are opposed to abortion. john: and specifically, he's complaining about the biden administration's repeal of what's called the mexico city protocol, that not to use any funds to any group that provides abortion. jennifer kates: when it's in place, and it's always been put in place by republican presidents through an executive action and then it's been rescinded or removed by democratic presidents through executive action, is a policy that says when the u.s. is providing foreign aid to other organizations, to foreign ngos, non-governmental organizations, it cannot provide any of that funding to organizations that use their own money or any other money, non-u.s. money for abortion-related activities that are prohibited, that even are legal in their country, but may be probited under u.s. law. so basically saying we're not going to give you money for abortion because we can't fund

abortion, but we won't give you money if you do anything else related to abortion. john: pepfar is established in permanent law. what differences will it make if it doesn't get reauthorized? kate: there's essentially two kinds of laws, reauthorizing laws a appropriations. and we always focus a lot on the money. that's the appropriations side. but there is these laws called authorizing laws or reauthorizing laws. those create programs or continue programs or structure them or have requirements on them. pepfar was authorized as a permanent part of u.s. law. it doesn't end as long as congress continues to fund it. so tt's the good news. however, there are some requirements and specifications within the authorization. its reauthorization that do end and they did on september 30th. so those were essentially requirements on how the program should fund certain things, and those are no longer requirements. this is a real symbolic departure from its past. and i think that's the main aspect right now that most are focused on. by by getting to a point where there can't be a bipartisan agreement to reauthorize it and

what message that might send on the ground and to other partner countries. john: jennifer kates of kff, ank you very much. jennifer kates: thank you. ♪ john: a warm fall and expanding extreme drought conditions have helped water levels along the mississippi river drop to record lows. special correspondent megan thompson reports from missou on what conditions on this vital commercial route mean for farmers who rely on it to get their crops to market. reporter: october is one of the busiest times of year for iowa farmer robb ewoldt. his crops are ready for harvest, and he needs to work fast to take advantage of good weather like today. >> we e currently harvesting soybeans. we are we are hauling them directly down to the river terminals for export.

reporter: ewoldt sells his soybeans for export because that's where he gets the best price. and lucky for him, his farm in eastern iowa is just a few miles from the nation's most important grain shipping corridor. flowing 2300 miles through the heart of the country, the mississippi is the nation's second longest river. it's also a superhighway for american agricultural products. around 60% of the grain exported from the u.s. is sent down the river by barge to the gulf coast. for some farmers in eastern iowa, like ewoldt and his friend joe dierickx, access to the mississippi is critical. >> it's very important. it's a vital part of our operation. >> the mississippi river is really our lifeline for exporting around the world. reporter: usually, ewoldt and dierickx spend these hvest weeks driving nearly nonstop, back and forth from their fields to grain elevators on the river, but this year, their routine was upended. ewoldt's semi trucks got stuck in two-hour lines, and dierickx was told not to show up at all. >> the elevator told me that

they were full. they didn't have a barge that they could dump any more beans into, and they were going to close at 2:00. reporter: closing unexpectedly, because the giant barges that are the main mode of transportation are having a hard time getting up the river. in october, water levels dropped the low levels are exposing the riverbed and rock, slowing down the thousands of barges that operate here. >> i've dealt with low water before, but not this low. reporter: brandon phillips is a towboat captain for the american river transportation company, or artco, a subsidiary of agriculture giant adm. with 2000 barges on the mississippi, it's one of the largest operators in the u.s. when we met philipps in october, he'd just returned to st. louis after 31 days straight on the

river. >> these are just our typical hopper barges we will tie them together with steel cables, and then we'll hook them up the boat and push them down river. reporter: the barges fill up at river terminals like this one in st. louis, where grain is trucked in to be weighed, then dumped and stored. a chute delivers the grain into the barges, which are then tied together into huge fleets. chad hart is an agricultural economist at iowa state university. >> as we're thinking about the barge system why do we rely on it so much? it is because it is the most cost effective way for us to move our crops up and down the river. reporter: according to a study by the texas a&m transportation institute, one barge can carry the same amount of dry cargo as 16 train cars. or 70 trucks. barges have a much smaller carbon footprint, too. >> so it's an incredibly large amount of grain that you're able to move quite easily and effectively down the river when we have full capacity along the mississippi. reporter: but this year, the

barges are only carrying about two-thirds of what they normally would. the lighter loads help them float higher in the water to avoid getting stuck on the river bottom. the low water also means the river is narrower. in a normal year, artco could lash together 46 barges of grain for a trip south. this year, the most they can fit is 25. >> we are not loading the barges as heavy, so we have to make more trips. so you have more boats down there taking fewer barges, doing more laps. reporter: and those laps are taking longer, in part, because the shallow river is harder to navigate. >> we've got these two red triangles, that tells me that it's gotten shallow on the back side there. that tells you to take warning. reporter: even with the warnings, boats can run aground. that could mean jamming up river traffic, and turning a trip from

st. louis to new orleans that normally takes 5 days into a nine-day voyage. >> it's a lot of work. takes a lot of planning. take a lot of communication with other vessels because you have a lot more traffic to deal with. it's nerve racking, you know, even being as experienced as i am, i don't have control over what other people do. i don't necessarily have control over what mother nature does. reporter: the barge problems caused prices for shipping on the mississippi to spike this fall, right when farmers were trying to sell their grain. to make up for the increased freight costs, grain buyers lowered the price they offered farmers. >> they pay us less. that cost is pushed back to the farmer. reporter: you can't turn around and pass that cost on to somebody else. >> i would love to pass that on to somebody, but i can't. reporter: dierickx says he lost about $15,000 on his soybeans compared to last year. robb ewoldt is down around $25,000. >> i don't think anybody wants to take a $25,000 hit to their paycheck. reporter: the issues on the mississippi are adding to another problem. over the last few years, high transportation costs have begun

to hamper international trade prices for american goods, says economist chad hart. >> so it makes us less competitive in the international marketplace. over the pt couple of years, argentina and brazil have been able to erode our market share in certain key markets, especially as we look into china. reporter: that the barges are still able to reach these markets at all is thanks mostly to the u.s. army corps of engineers. since mid-july, the corps has been keeping the channel open by dredging, sucking out massive amounts of sand from the river bottom. >> what we see is our dustpan. so, our dustpan's our vacuum cleaner, 35 feet wide. reporter: lou dell'orco is the chief of operations for the corps' saint louis district. he oversees this massive boat, called the dredge potter, working near scott city, missouri. the boat moves this machine, a huge vacuum, around the bottom

of the river. >> once the dredge sucks it up from the vacuum cleaner, it runs through a pipe. the pipe goes from the front of the dredge, all the way out there and there it's deposited all the way outside of the channel in an average day, we could move about 50,000 cubic yards, or enough sediment to fill an olympic sized swimming pool every hour. reporter: a rotating crew of 35 people live on the boat for around three weeks at a me, running the dredge 24 hours a day. >> this screen here, it shows you where we're dredging at, where we are digging. reporter: it's one of 8 army corps dredging boats working on the mississippi right now. it's hard work, made harder by the fact that this vessel was built in 1932 and requires a lot of maintenance. >> they' maintaining a 91-year-old vessel and there's challenges abound and the team keeps it together. everybody's dedicated to the mission, which is maintaining the channel, which supports the nation's economy.

reporter: dell'orco's team could be out here until winter. when, everyone hopes, snow and rain will finally arrive and replenish the river. returning water levels and business back to normal. for pbs news weekend, i'm megan thompson, in scott city, missouri. ♪ john: and tonight, for our hidden histories series during native american heritage month, the story of a decorated naval officer and trailblazing astronaut. >> liftoff of space shuttle endeavor. john: in 2002, when john herrington became the first native american in space, he carried with him pieces of his heritage, including the flag of the chickasaw nation. >> three new residents headed for the international space station.

>> i also flew a flute and a feather. the flute was made by a erokee friend who was an engineer at the kennedy space center. an eagle feather was given to me that was beaded mother earth, father sky and all the people of the world. the only two items that i was actually able to take out during my mission and photograph. john: herrington was born in 1958 in wetumka, oklahoma. he grew up during the height of erica's space race with the soviet union. like many children then, his heroes didn't wear capes, they wore spacesuits. herrington's father was a flight instructor. he spurred his son's interest in aviation by taking him flying. >> early on, my brothers and i would sit in the back and we'd fly to oklahoma. and later on my dad bought a little cessna 150, and we used to fly. he would say, here, fly, and i'd fly. he'd lean over me and take pictures out the window. john: he graduated from college in 1983 and went to the navy's aviation officer candidate school. in 1985, he was commissioned as a naval aviator. over the next 10 years, he had a

variety of assignments in the navy, logging more than 3800 hours flying more than 30 types of aircraft. in 1996, a childhood dream came true. nasa selected him from 2500 applicants for one of the 35 slots in the new class of astronaut candidates. >> this view of john harrington working in the vicinity. john: he went to spacas a mission specialist on the space shuttle endeavor as it delivered a new crew to the international space station. during the 13-day mission, herrington completed three space walks. his nasa career went from space to the depths of the ocean. he spent ten days in nasa's underwater aquarius lab to study survival techniques for spac exploration. for his achievements, herrington is in the chickasaw nation hall of fame and the oklahoma aviation and space hall of fame. now retired from nasa, he's an ingenous scientific storyteller, traveling the world, combining chickasaw oral storytelling traditions with his love for science and space.

his new mission is not only to inspire more young native americans to study science, technology, and mathematics, but to burst preconceived notions about american indians. >> a lot of people have this stereotypical view of what a native american is. in reality, we're engineers, we're scientists, we're doctors, we're lawyers. we appreciate and we value our heritage, our ancestors provide us the opportunity to walk the earth, and so to be able to recognize that it's not just that we're proud of who we are, but proud of what we do. ♪ john: now online, why the cdc recommends that infants be tested for hepatitis c as part of the effort to stop the infection's spread. all that and more is on our website, pbs.org/newshour. and that is pbs news weekend for this sunday. i'm john yang. for all of my colleagues, thanks for joining us. have a good week. ♪
