>> sreenivasan: a narrow 51-49 vote against calling witnees or adding new documents yesterday set the stage for what is expected to be a party-line decision to acquit the president next wednesday. >> without objection, so ordered, we are adjourned.>> sreenivasan: after two weeks of argents, amendments and questions senators agreed to take a break for the weeke. they will return monday to hearo four houclosing arguments. then they will get a chance to make statements explaining their decisions before voting on the two articles of impeachment. the vote, now officially set for 4:00 pm wednesday, will happen after the president gives his y ate of the union address on tuesght. for more on the impeachment trial and what's next, alexis simendinger, nationatical correspondent for "the hill," joins us now from washington, wc. so, heare, an official igekend off because things are almost done,? we're just a few day from the end of a drama that started >> sreenivasan: if the votes

last night indicated a couple of different things, one is that the white house and mi mcconnell were able to g senators in line and make sure thatot enough voted for witnesses. but also aouple of kind of interesting commen from, say, on the one hand, tem toco rubio. agree with the house managersnt that the presi do these things and they were wrong. but on the other hand, they're not voting to want to hear more about it. >> it was very interesting to see the logic behind some of the senators whoere considered to be potential supporters of the idea of hearing from witnesses and to subpoena documents. you mentioned lamar alexander of tennessee. he's retiring from the senate. so there was some thought that perhaps on his way out, he might think that witnesses was a good idea. but in the end, what he said was interesting.d he sat he believed that the house managers had actually established e facts, that the president had done something

that he considered inappropriate in his effort to try to persuade ukraine to start anve igation into former vice president joe biden and his son. but he said, in his view, it wt peachable. and therefore, if he had decided it was not an impe thable offensre was no point in hearing from additional witnesses. senator marco rubio of florida, who we remember had actually challenged donald trump in the esprimary in 2016, also sud that in his view, there mightto have been merihe suggestion that the president had acted inappropriately, but it was not impeachable. so what we're going to be going into in these speees early this week and leading up to the votes on the tworticles of impeachment are additional statements from lawmakers about why they're voting in particular ways. and we know what democrats think, but there there's still some democrats we want to hear from. and then, of course, these republicans are very much eager to explain to their electorate and their states. susan collins from maine is a

republican who definitely wants maine.k to her constituents in she's up for reelection and she voted in favor of the idea of witnesses. >> sreenivasan: we these senators concerned over time that this increases the power of the presidency, that this createa situation where congress is less of a check on the president's power? >> it was the case in lisa murkowski's situation.li she is the repn from alaska. when she put out a statementab t why she was voting against witnesses-- she was considered a swing vote on that, that question-- she talked about how the congress had failed. the senate has failed.he souestion you're asking is an important one, that lawmakers in both parties, candidates in both parti are asking, because the conc is on basic oversight. is this now a president who feels unfettered and so unbound by the legislative branch, d so supported by the

arguments that the constitution gives him vastowers, that he will continue to flout or seek thys to exert his executive authority in way the congress is incapable of challenging? and that's coming up from national security advisers and national security experts, too, because the terrain of this impeachment was unue. it dealt with international and foreign affairs as opposed to domestic issues. and so the concerns in both parties actually are real goingw d. >> sreenivasan: all right. and we will have an opportunity to hear from the president over the next couple of days. well, multiple occasions, really. the first starting in-- is the pre-super bowl conversation that he has scheduled with sean hannity. >> we're going to hear a lot from president trump, as you mentioned. he's going to be doing a pre-game interview that will be e-taped. sean hannity is an enormous supporter of the president's. the president and his campaign have paid at least five million dollars for an ad during the super bowl. so we're going to hear his pitch

for reelection.t the presid also going to be giving us the state of the union address on tuesday evening. and that speech often withis president trumery much a teleprompter prepared speech. but it's an interestnamic nding in the, and before members of congress and talking while the trial is actually still technilly going on. >> sreenivasan: alexis simendinger from "the ll," joining us from washington. thanks so much. >> thank you so much. >> sreenivasan: today marks the first day after brexit. thousands of brexit supporters gathered in londonast night to count down to the exact momented the un kingdom left the europeannion. the official departure comes three and a half years after the country voted to leave the e.u. by a narrow margin of 52-48%.

starting today, the u.k.'s office in brussels is just an embassy. with brexit, the 62 year-old e.u. now has 27 members. in a video message on social media, prime minister boris johnson promised to bring the country together. >> it's not just about some it is potentially a moment of real national renewal andge ch >> sreenivasan: the u.k. n n has tootiate new trade deals, including with the e.u. despite the formal departure from the e.u., there are still signs of division. in scotland, where brexit was opposed by a wide margin, theran we protestsigns supporting scottish independence. joining us now via skype i npr's london correspondent, frank langfitt.e frank, you wt there on the streets yesterday when people were out there on this momentous occasion. what were they saying? who you talked to ere youeon went. was down at parliament square last night right in,front of big here there was thousands of people. some of them were wearing apion

jacks as around their shoulders. they were thrilled by this. they felt that this was thr independence day. other places you went, there were candlelight vigilof people, i think, sad, but accepting this, knowing that remaining in the e.u. is not going to happen. and even a few clashes i saw between reinders and leavers. ouso, there's still... you really see a lot of the divisions still in this country. >> sreenivasan: okay, so here you are waking up in this post-e.u. britain, and, if you're a leaver, well, the roses haven't started to bloom; and i' a remainer, the earth hasn't opened up and swallowed the entire island. so, what is the actual impact on a day-to-day basis? >> right now, almost nothing. nothing has changed this morning. and the reason for that is the last thing that the united kingdom or the e.u. would need is some sort of abrupt, you know, severing of th relationship. they now have 11 months in a transition period to try to work out a new free trade arrangemeno between th sides. and that's going to be very difficult-- in fact, much more

difficult, if you can e it-- than the last three and a half years that led to paralysis in the government here. one european union would like a much closer relaip. the united kingdom, they want independen, and that means ey'll probably have to pay for it with taxes and trade barriers. >> sreenivan: and that means that also when you say renegotiate, that means with each member nation? >> no, they'll be doing it entirely with the e.u. but what's really portant here, hari, that's important to remember, is the e.u. will now be 460... 450 million consumers and about 60-some here. so, this is a very imbalanced relationship. the e.u. has a lot of leverage. also, there's this short window to do this. so, that's a lot of pressure on the united kingdom if they don't want eventually crasat the end of this year. >> sreenivasan: right. led then, what about scotland in the mif all this? >> this is absutely fascinating. what's going on with scotland right now is, as you have the brexiteers cheering, you know, in parliament square, you have people up in scotland saying, "we never voted for brexit. we don't want to leave the e.u. we want independence.

we want a referendum as soon as we can get one." boris johnson has said the prime nister will not do that anytime soon. but it's conceable within in the next two or three years, there could be an independence referendum. ard i think the nightmare sc for the u.k. is, you eyow, people like boris johnson, the brexiteers, et brexit, they leave the e.u. and they lose scotland in the process. >> sreenivasan: and how important is scotland in this, and why do this matte ? >> well, iso spent quite a bit of time in northern ireland. they're watching scotland. there's a movement now, more... more energy to eventually reunify with the island of ireland. so, you can feel things really straining here under brexit, and there could be a domino effe. it's not out of se question. enivasan: are there parallels between what's been happening in the u.k. in the past couple years and what's perhaps happened in the united ates quite some time ago? >> tons of comparisons in terms of 2016 election and he. i find often as i travel-- particularly, i spent a lot ofti in the north of england-- these are post-industrial communities. and when youave conversations with people up there, hari, i mean, they say the same sort of

things you would hear in michigan and pennsylvania. country changing too fast, sufferinfrom globalization. they feel that they've been left behind by elites in london. it's all the same kind of language, but it is very heartfelt. and what boris johnson was able to do in december was to go up there and speak to people, promise to get brexit done and then reinvest in the north. and that was the way he was able to win a big election. so, what he did up there is not dissimilar at all to what donald trump did in the upper midwest in 2016. >> sreenivasan: so, here he is now, at least part one of getting brexit done-- making the in-- is over.rwork, mailing that but reallyyou're saying that harder than the laeeld be years. .> much more difficult. negotiating over renegotiating all of these sectors, whether it's a agriculture omotive. i think it is going to bmuch more difficult. and... and the worstabout it is, there's such a narrow window of opportunity. xnormally with these comp

trade deals, they take years and years. >> sreenivasan: yeah. >> boris johnson has said, "11 months, and we're out."iv >> srean: and what are the economic impacts? are they being felt yet in the u.? >> they've already... you know, in a sense, hari, the... the united kingdom is already poorer. loght now, the pound is still 10% the highs that it had just before the brexit vote. so, people have already fe that. i will say employment is very good. unemployment is very low, but grth is very low. and there are... economists that i talked to are concerned since there's still so much uncertainty about what kind of trade deal that they get here recession sometime thisto year. >> sreenivasan: npr's london correspondent, frank langfitt, joining us v skype tonight. anks so much. >> you're very welcome, hari. an >> sreenivtoday, more countries expanded travel restrictions to try to prevent spread of the new coronavirus.

correspondenchristopherta livesas us to jordan, where the united nations world food program is using technology and digital innovations to ustter provide food to hundreds of tds of syrian refugees. this report is part of our ongoing "future of f sd" series wiport from the pulitzer center. >> reporter: jordan is home to nearly three million refugees, which makes up roughly 30% of the country's polation. the refugees here come from various countries including iraq, palestine, libya, iran, and more than 650,00hem are syrian refugees that fled their country's civil war. 80% of syrian refugee households cahere struggle with what'ed leood insecurity," the inability to secure reliab access to affordable, nutritious food. this surge in population combined with the dry, harsh weather makes growing enough food here extremely difficult. in ord to feed the entire population, jordan has to import

re than 90% of its food. and, as for water, it's running out. >> ( translated ): jordan faces water scarcity, even drinking water is not always available. the most water-scarce countries in the world. khaled al-hisa is a director in jordan's ministry of agriculture. >> ( translated ): syrian demand and pressure on the natural resources we have in jordan. the government has to think outside the box. >> reporter: ithis case, that ans trying to find a better way of growing food. to do , the countrorking with the united nations' world food program. jacqueline degroot i of w.f.p.'s jordan program is unit grows barley hydroponically, using water but no soil. the baey is used as animal feed. >> so the seeds are put here in one ofhe trays. after a uple of days, the seeds immediately start growing. you can already see some sprouting happening. >> reporter: the seeds are

placed in trays and watered for just 3seconds a day. in seven days, the barley isgr fulln. and in a country given to drough, this uses 90% less water than traditional methods do. cycle.this is at thend of the so this is ready to be eaten by animals. >>eporter: and so you're trying to roll this out for refugees living in tents. >> this high tech unit is really meant to do the research. so we know the best way to roll itut into a much smaller low tech units that are locally sourced that are much cheaper, obviously, and therefore it's going to be rolled out in the whole country. >> reporter: got it. so it's high tech now, so it can be low tech later. >> exactly. >> reporter: theow tech hydroponic units consist of simple plastic walls with rows of bins inside. ey produce lush, green fodder used to feed animals including cows and camels. one key component of this program is teaching local refugees how to grow the food anmaintain the units >> (stranslated we wash the

seeds, we plant it and we we sell the barleye maker. money. whhe i first came to jordan, living conditions were very difficult. thanully things got better. i started working in hydroponics and then things at home improv. >> reporter: so far, w.f.p. is running its hydronics program for refugees in seven countries. the influx of refugeesn this country has put a burdenn the already-tight job market, so creating employment opportunities is critical. in jordan, t hydroponics program has created 177 jobs. did you ever imagine that you'd one day be farming with hydroponics? >> ( translated ): no. i never thought that i would work in hydroponics or anything like that. >> reporter: did you have any experience in farming in your life? >> ( translated ): yes, we used to plant in our home in ria, but that was the traditional farming, not hydroponics. we came here and there wereop already working on the project.

they trained us well so i didn't face any difficulty at all. en>> reporter: this 21st ctury system o represents w.f.p.'s push to use new technological approaches to providing food aid. more than 100,000 syrian refugees live inside camps. the camps are so big in fact, that they have regularts supermarhere people go to buy food with monthly stipendsf. provided by people choose what they want and make their way through the crowds. but it's the checkout hat makes this supermarket unusual: the refugees upa their eyes to through iris scans. the scans are rified remotely w.f.p., which keeps track of everyone's accounts. >> so, they look into a little camera, which is an iris scan. the camera records their irises, verifies this is indeed e person that is allowed to do the shopping, and then the payment d e. it's the same technology that now, f example, is used at the airports, so it's not a new

technology. it's however not that common yet to be used in supermarkets. it's futuristic, it is the future. we see it more and more. f reporter: it also mak it hard people's aid money to get stol, because they are the only ones that can access it... with their eyes. >> it is a safe and secure way d ensure that the people that have receie money are also the people that are buying the food. >> reporter: nearly 500,000 refugees are using this in jordan. degroot says there is no silver bullet for providing food aid to advances in technology is anng imrtant step toward ensuring evne has access to food. e in a place like this, where you can seere is absolutely nothing else, thing grows here, people have nothing else the aid that they are getting. it is very important for us to hep innovating. innovations realp us being efficient, being relevant and making sure that we caide the best aid that we possibly can.

>> this is pbs newshour weekend, saturday. e southernasan: african nation of zimbabwe is another country where harnessing the power of hydroponi is helping to limit food shortages and is providing one local wom an opportunity to grow a new business in her own backyard. in a small greenhouse in zimbabwe's capital, harare, venensia mukarati is preparing her lettuce for harvest. an accountant by day, mukarati was looking for a way to explore her passion for farming. but with no access to farmland she looked for other options and stumbled across hydroponics. instead of planting crops into soil they are grown in water and draw nutrients from the liquid. mukati ordered a hydroponics system and soon began farming in her own backyard. >> hydroponics farming saves water and i really enjoy it because i don't haverry about water, i don't have water

here, so i have to buy water but because its hydroponics, i ang saater by 90%. >> sreenivasan: water be conserveuse it is reused several times. this means in a country like zimbabwe that's experiencingou drt, water goes further. ind there's another benefit. >> when you are hydroponic farming your crops grows faster by a third, and you tend to riharvest it in a shorter conventional farmirming in the soil. >> sreenivasan: it takes about six weeks r mukarati to harvest her vegetables compared to about ten for plants grown in soil. that means her ctomers, restaurants and markets in harare, get their produce quicker. her business now makes her over $1,000 a month. this is in a country where the average government salary is less than $80. and this new income has mukarati looking to expand her business. she already trains others in hydroponic techniques. and she hopes to be in a larger greenhouse before the end of the year.
