on the groun of drake university where a couple of caucuses are being held righ now. you've been in the state over the weekend you've been to several rallies for these candidates. a sense of almost desperation comes ac tss when youalk to these voters they seem to be -- have made it so important to defeat the president. how do you distinguish from one rally, one can't date to another in how their supporters are coming across and what is important to them? >> well, i tell he you, they are sort of blending in, they don't sort of listen so much to the policies and issues they are sort of looking for the emotion. the feeling of dave and his wife sanders rally in decree car rapids, it wasn't so much what they were going o hear but what they were going to feel from the candidate. they wa candidate who can make a connection. get people outo the polls. there is thisense of, as you say, wanting to get this right. they know thangt they're lea that concept off they want to pick the right candidate in their minds, the can't datwho they think would have the best chance of winning in november. and, even though some of the candidates are a little bite diverse in thir policies, some a little farther to the liberal and progressive side, some to the moderate side. a lot of democrats say that no matter what they support now, no matter who gets the nomination, they're going to votfor them. there's no sort of ideological purity this time around, they just want to defeat donald trump. >> woodruff: it really doeem o come back to that. i'm just struck, we've all heard that sayings the vo you cast for president is the most personal one you ever cast. eople really doed to feel voting for.he person they're but april struck, john, by the comment that some seem afraid of making the wrong choice. >> that's also whas keeping so many people undecided or kept them undecided even now going i suspect there's some peoplen, undecided. into their caucuses iting to hear from their friends, their neighbors, hearing the arguments abut the candidates maybe making that last minute decision in the caucuses themselves. >> woodruff: john yang,re rting from break university also with us is the "newshour". daniel bush who is inside one of those precinct caucuses on the campus of drake university. so, dan bush, tell because it's like, whating on inside inside that caucus? >> judy, first round of voting e just ended a cou minutes ago. now they're going through, this is the aliment process there was some drama here this is one of the bigctgest precin the state. they were expecting about 1200 voters here more caulk is goers 50% turn out over 2016 we'll see what the final number is we the first tally came in, warren won with 212, the threshold for vie lilt, to stay into the second round was 127, sanders just barely -- bernie sanders just barely made it by two votes, a gasp went up in the crowd. joe biden, former vice president joe biden just nearly crawsed the threshold when bide was on the bule he has a very experienced precinct team here they polled in just enough people amount the last minute to get him over that threshold now we'll see who alliance with who in this next 20 or so minutes. >> woodruff: you're right. cause there will be a difference once they get to thed selignment or realign the. dan bush, where is pete buttieg? >> good question. pete buttigieg finished in so he moved on to the nextotes. round. this is an area that includes a t of upper middle class neighborhoods here in des. moin it's not very diverse, it's a territory that has been friendly seemingly to elizabeth warre to pte buttigieg not a huge surprise he did well. but did speak to the divide among moderate voters at least who sided with buttigieg over joe biden. amy klobuchar gt 140 she actually hotperformed biden a little bit whiche am a surprise. >> woodruff: very interesting. so interesting what you said about both saders and warren. or rather sanders and biden, just barely makg viability. so-called buyability which is 15%. o now year you gotoep a close eye as are we. we'll talk to you later tonight. dan wish, thank you very much. >> woodruff: in the

echo an argument made by mr. trump's attorneys: that while th president did withhold aid to ukraine, in a pressure campaign to investigate former vice president joe biden and his son hunter, what t

before the house or it's in his wok or it's in one form or another, the trul continue to come out. >> reporter: president trump, who spent the weekend at his mar-a-lago home in florida, was wholly dismissive when asked about the triain a fox news interview. >> your reaction to all of it? >> well, it's been very unfair. from the day i won. it's been a very, very unfair process, um. the mueller report, russia, russia, russia. as you say, which was total nonsense. it was all nonsense. the whole thing was nonsense. >> reporter: the president will stand before the same lawmakers litigating his futurffice, when he delivers the state of the union address tomorrow. for the pbs newshour, i'amna nawaz. t >> woodruff: ngive us the latest, our own lisa desjardins and yamiche alcindor. so good to see you in person, rather than reporting from the capitol. >> woodruff: so much to ask you about, but lisa, let me start with you.gi us a sense of the core of the argument that the house managers were making today. several different directions. >> they did have a few different arguments they were making. let's look quickly at a graphic, and amna summarized some of is, to make it very clear, the number one argument from house democrats is that thident abused his power and obstructed congress. tose are the charges agai the president. but they're going beyond that. s ey're also saying if he is unchecked, if het removed from the office, this president will do it again. they s that is a threat to national security and the 2020 election. they also are maki this argument we've heard from representative schiff in that story that history will judge the senate. they areaking a historical argument as well. judy, however, some democrats are king another proposal tonight, senator joe mansion is proping not removal, but instead censure of the president. we have his sht resolution to that effect. this inot the first time this has happened. in 1999 withlinton, senator diane feinstein proposed censure also as an alternative, that did not go very far. i haven't heard a huge appetite for censure except for a few senato so far. >> woodruff: interesting. yamiche, how do they feel at the white house as this is unfolding. the fact that censure is at least a proposal and the fact that president will be giving the state of the union tomorrowi t. >> reporter: first of all the white house and president feel very confident in the argument that the white house leader made before the senate. they don't like the timing of this.t the presidnted to be acquitted before the state of the union, but that said the was the legal tepended it, they were echoing things he was saying defending himn social media in interview before the senate trial, let's walk through what the white house team said. they said that the democrats have long want to impeach the esident. they said that basically since 2016 democrats have had it out for president trump and were angry because they didn't like him. they also said foreign policy includes politics. this is the argument thathe president is going to have political differences with people, people that work for him and essentially his policy differences are what makes foreign policy that it is okay to talk about politics and foreign policy. they also said acquittal means defending democracy. this also goes to the idea of history. they say that the president should not have to deal with his national security advisor andr otople being called up to the hill to testify about personal conversations that they had with the president. the other thing when it comes to censure, the white house acknowledges that the censure argument might be something they have to deal with later but they think that will fail. at the end of the day the president thinks he will be exonerated, acquitted and thatwi be the big thing he will be able to talk about. >> woodruff: well, speaking of that, this argument ome republicans have made, like lamar alexander who said, well, what the president did in reaching out to ukraine's president, asking him to investigate a politival was wrong, but it's not impeachable. how is the white hou dealingt? with t >> reporter: well, the president pes said over and over again that his call waect. but the president's own legal likely going to voacquit are him, they are not making that argument. the president, here is what the president was saying on twitter. he said "i hope the republicans and american people realize thao thlly impeachment hoax is that, a hoax, read the transcript.th read wha president and president of ukraine said, n pressure. nothing will ever satisfy the gamocrats." the president's team is also saying tonight that they are happy with the idea th senators are saying maybe this call was problematic but it's not impeachable. robert ray told that to our white house producer. i also talked to alan dershowitz who said he is okay with that because there were moral problems with the call. the president is not acknowledging that at all. he is just pointing to the fact that he is going to qu ted. he doesn't want to think about that too much. in terms of what we are goin e look at in the future, president feels emboldened. he feels like i can talk to china, to india, about what dirt they might have on bernie sanders or joe biden because republicans say it is okay. >> woodruff: doesn't sound like om's going to come around to the idea that he didhing wrong. >> not at all. >> woodruff: so lisa, did a >> woodruff: so lisa, did a dig more deeply if you will into the senator's senator's thinking, there is so much pressure on almost every one of them calling fromll directions. >> yamiche and i spent a lot of time in that senate chamber oved the past fs. i think we agree that today you could see senators had mentally already moved on, as if they made their decisions a few days ago. it will soun it was almost like watching a group of people who had a very large meal having to listen to a like they were all really more or less tuned out. even t biggest note takers. >> woodruff: with all compliments to the d.m.v. >> with all compliments to the d.m.v., thanyou for my license, i'm happy for the privilege to drive. but you could tell it seemed like sators, the big moment of drama had seemed to come and pass. but that said, there is still an open question, at least about three democratic senators whong we're watcarefully. these three senators in particular were watching to seen if they vo guilty along with republicans, nator joe manchon said he sun decided. one because he is up foreresting re-election this year. and senator fromrizona are folks who have indicated sometimes at least inco eration to some more conservative ideas, there is still questions but it felt like the senate was ready for ts to move on. we are getting those announcements tonight and tomorrow. >> woodruff: and the vows wednesday. alcindor, thank you.he >> you're welcome. >> woodruff: tonight's "first in the nation" caucuses in iowa:y they are not oe kickoff to the democrats' presidential nominating process this year, but also the start to a jam-packed week of political events. john yang is back, and he picks it up there. >> reporte judy, on the agenda this week, tonight's iowa caucuses, tomorrow's "state of e union" address, and wednesday the trial verdict in the senate impeachment tal. and that's also the agenda for politics monday. amy walter of the "cook political report," and host of "politics with amy walter" on "wnyc radio," and long-time iowa political repoer david yepsen, he's host of the "iowa press" on iowa pbs. david, thank you very much for joining us. we don't have official numbers we won't have official numbers from the iowa democratic party for some time, but we are getting indications through the 'associated press vote cast survey of iowa voters which has been goiang on for sixys before the contests. amy, you've been looking at the numbers, what have you been seeing? >> what we're looking at is kelp combative break down, who is showing up, are tere nw voters, what percent of the electorate howre they dividing themselves. what we have seen and -- from the vest ca tst amoe very liberal voters, for example, i don't know if we're table to bring that up. but among very liberal voters, bernie sanders doing very well as you you can see, he and elizabeth warren accounting for about th% of all oe people who define themselves as very liberal l t89 now you ge to the liberal voters once again, it's sanders and warren who are leading the way. but rith buttigiegaking in to the top three here, and this isn't that surprising, of cose, but whis surprising is the next slide which is moderate voters. this is a group of vote that's right joe biden has interesting go specifically at, part of the reason he's doing so well isis polls on those people o define themselves as moderate to moderate conservatives. here at least from this vote cast, data, th that vote is getting split with amy kolb bar and pete buttigieg. bernie sanders, elizabeth pgh wren domining and half of the voters sayeing they a 6 moderate makes it more likely rat you'll see someoneom the liberal camp in to the top of the caucuses.do >> we't have official rtmbers but we just had a re from david yepsen, who stopped by to tell us r theeport from the caucus, your precinct, david. that elizabeth warren, the top three finishers, elizabeth warren followed by pete buttigieg followed by amy klobuchar then senator sanders and joe biden just barely abov viability. in fact klobuchar, the klobuchar caucussers sent two of their members over tod the en camp in order for biden to reach viability. obviously one precinct out of many. tell us what you -- >> i'm glad you're covering -- let the record show but it squares with what we're seeing. mod rad, this is a -moderate, this is blue collar precinct with students in it, has middle class, upper middle class, nice combination of people. fact that bernie sanders was trailing in the back i whi a sign that he's a littltoo liberal for this of those people. i think joeden performance here is probably pretty telling, too. a lot of peoouple worried ab him, how dynamic he would be as he passed his prime, what i should have done count the yar signs on my way to work here. because that's what the yar sign count would indicate, too. >> amyob klhar's strength. >> coming up. this is -- she's the one that could get the big boost out of iowaf his repeats itself elsewhere. i'm not sure she can. the fact that she's been pinned down in the senate imachment trial has limited her abity to be on the road doing events here should be to be gaing.hought >> so much of iowa is sort of expectations, what you meet expectations, sort of the momentum effect. given the fact that we have the state of the union address tomorrow night, the senate impeachment vote wednesday d. this going to mute the affect? >> it's a very good question. becausell norat this time of the year, iowa as the entire political focus ont. and folks would have been here for two wecaeks broing, every little tiny movement in the state. now it's had toompete with the cable news networks have been filled with impeachment, notth iowa, now tomorrow morning people are going to wake up there will be a winr of the iowa caucuses that will hae impact on think, who do i like, who should i vote for. but for number where it is only a week from now that they will go to e polls. you are not getting that big build up in the - biall that talk about expectations. it mayort of blunt some of the momentum or if you did not do as well. blunt some of that, uo, you'rein to be desperate. >> i think amy is right. the impeachment thing has muted the iowane megapere not just in new hampshire but around the untry. the old adage, top three senators, may not hole.d tr >> more people, more candidates could keep going.th got the money, organizations there, may be not as pronounced as is been in the past. >> in fact numbers we're getting, three diffent numbers tonight. what affect is that likely to ha or could that have? >> we were waiting to see, basically the division in iowa looks la lot like national vote where there's a popular vote and electoral college vote. here in iowa the total number of votes, first cast by voters, that number is going topoet ed for the first time ever. but there wi also be at the end of it, the number ofga des that are awarded to these candidates. those numbers may not be the same. like the electoral college, iowa 'prices being tble o be geographically diverse.vi your support vet out around the state. those candidates will be recorded wth delegates. here in des moineu can getlike a big number. >> amy walter, david yepsen and david yepsen's wife tonight, that is politics monday, thanks a lot. >> woodruff: governments around the world are ramping up their aksponse to the viral outb that's emerged

could you just give us a sense, the modeling that we have seen indicates this is likely going to become a true global pandemic. or do you think it too early toe make that call? >> i think it is very dangerous future course of an unknownhe virus. we can tell you where we are ane wherave been, but there are so many unknowns about this novel coronavirus, that is what we look forward to working with china to get to the bottom of it, how transmissible is it, what is the severity profile, do we see asymptomatic transmission, questions like that are the type ofions we have to get to the bottom to thhe will help us understand curve that we're going to see on >> let's say that models are accurate and we do start to see a greater spread not just in china but elsewhere, perhaps even in the u.s. is it your nse that our emergency response capacity, hospitals, doctors, nurses, that thoseti faci are prepared for that type of an outbreak? >> well, we're proactively preparin we've been working on pan demic preparedness for a couple of cades now. so we have a very robust, the best public health system in the world here. we have been identifying cases in the united states because of that health system. we have ucated our doctors, our nurses, our health-care providers to look for symptoms and to ask people questions. that is how we have found the 11 cases that we have here in the united states. and it is going to be that good old-fashioned basic blocking and tackling the public health, a multilayered approach, look for symptoms, isolate, diagnose, treat and do the contact treys treysing on others, we know what we have been doing. we have the best, most experienced team. i myself was here for 9/11, anthrax, smallpox preparedness, sars, ebola, monkeypox, hurricane katrina, so we have a team that knows what it is doing here. >> let's talk a little bit about the announcement on friday about the new travel bans and quarantines.am noicans who have been in china with a few exceptions wilc largely beded from the country. americans who have been inil mainland chinabe screened when they arrive at one of those 11 airports. maybe quarantined if they show symptoms. americans who have been in wuhan will automatically be put into a two week quarantine. maybon military bases. some public officials argued quarantineand travel bans may not be the best approach. can you make the cu e as to why ink it is the right approach? >> sure, right now for every day americans the risk is quite low for this virus or anction spread. our job is to try to keep it that way. what we want to do is focus oura limited publich resources where they matter most. so right now we keep bringing americans back from the impacted areas of hubai province. those individuals do need to be quarantined for up to 14 days. and that is actually consistent with what other major powers are doing with their own citizens when they are bringing them back. that is the incubation period. sose have to focus resource there.as or other americans coming back on commercial craft from s chine thing, a very risk titrated, individual approach. asking those people who have been in main land china to self-isolate so they will have 14 days from when they last were in china until the point that members or communi at risk.ily we see great compliance on these measures. he with ebola we saw 98% compliance on volume tear measures like that. we are trying to be very temporary, titrated, measured and incremental in this approach because the risk again is low, we want to keep it that way. >> as you know guarant something we haven't done in the uned states for decas. is it your sense that people will comply with this an tlet's just snsmission does continue and you need to guarantemore americans, it could be very big number of people who are basicly being locked up for two weeks, do you think people would be okayith that? >> again, these measures are very tailored to individuals this outbreak.e epicenter of 57% of the known cases in china are from this one province. we're talking about the veryer small nuf american citizens who have been in that i provinthe last 14 days. china stopped people being able to exit on january 21s. so we are almost actually at 14 days at this point. so a very small segment of people. and then as to china, the broader mainland china, restrictions we have are really volume tear asking people for your own protection, protectiond of your familyour community, just stay at home. please isolate, call your publil department as you experience any type of symptoms like temperature, or body aches or respiratory symptoms. these are things people want to do to protect themselves. they are cognizant of this. wedohink we'll all be able t this all together it shouldn't be a major inconvenience for people. and we can hopefully slow any potential spread whiwork in partnership with the chinese government. china has taurn extreme me. they have isolated 50 million people ayou said in your opening segment there. 're working in concert with that, it's almart a complimeapproach. if china can contain this virus within a portion o wchina and thhin china and we in other countries can keep further spread, that show this can eventually be brought down, hopefully. >> secretaryf health and human services, alex azar, thank you very much for yourime. >> thank you. >> woodruff: the work of women artists makes just 3%-%5 in major museums in the united states and europe-- and many have struggled economically while making their art. susan unterberg is an artist trying to change that. she worked in the shadows for decades as an anonymous benefactor. jeffrey brown went tnd out why she decided it was important to finally put a public face to her philanthropy. it's part of our ongoing arts and culture series, "canvas." eporter: a large gatheri of artists in new york's madison square park, to share something and someone they had in common: all had benefited from a grant given anonymously for more than 20 years. >> hello, everyone! >> reporter: and last summer now, they had the opportunity to meet the woman behind it. >> the gods have given us thebe day of the year. must be the female gods. >> reporter: a fellow artist named susan unterberg. since 1996, unterberg has helped support 240 womeartists with grants totaling $6 million, money she inherited when her father died in 1992. >> it changed my life. >> reporter: the award is aimed at women in mid-career, over age 40, when as unterberg had seen herself, opportunities for women artists have historically grown sparse. >> i knew firsthand thathere ofs a huge need for suort in this middle raomen artists because there was a real when they are starting out, fresh out of graduate school, they might get picked up immediately by galleries and they had a bit of fame. and then now older artists are >> reporter: much older. >> much older. but the mid-career is almost like a desert. >> reporter: why do you think that is? >> it's nosexy or seductive. >> reporter: unterberg experienced early success as a photographer. mee wanted her later work to be judged on its owts and decided to keep her philanthropy a secret g she called tnt program "anonymous was a woman," a line from virginia woolf's book, "a room of one's own," about how women arsts through history had gone unacknowledged. but not puttinher name to the grant also suited her. >> i am very proud othis grant but i still like the life had, which was more one of anonymity. >> reporter: anonymous was you. >> absolutely. >> each of these is a version of >> reporter: one newly-named recipient, elia alba, told us of her reaction to winning the grant. >> i started to cry. >> reporter: you started to cry? >> yeah, i started tcry because of the nature of this grant. it really honors wen and i'm in, like, super great company. so many artists i admire. and then of course i said, "but elia, it's $25,000, so that was really great." >> reporter: alba, whose family comes from the dominican republic, creates work, like these dolls, that examine race, gender, and the sense of belonging in america. part of her income comes from an lministrative job in a le and investment banking practice. the art isone mostly nights and weekends in her studio in this large artists space in the bronx. the grant, she says, will allow her to buy equipment and hire a assistant to deded prep work. >> for me, these awards are a validation. >> reporter: that says what? that says, keep on working. keep oerworking. s ageism in the art world, i think you' kind of ignored because people areoming up. for me, i find myself questioning, "am i dng the right thing?" it may sound corny. it gives me hope. it gives me a lot of hope. >>ainiature landscapes, lik siniature mesa. >> reporter: amiel, based in brooklyn, is another of the artists from the recently- announced "class" of awardees. >> it's so moving to know that there was a woman o began this award in our era of self promotion did it not to call attention to herself, but to call attention to others. it's lovely. it's phenomenal. right now, i'm working on a piece that was partially filmed in the desert of the emirates. the displacement of sand, but >> reporter: she sees her work-- photography, sculpture, performance and painting-- as revealing hiddeneanings and histories in the things all around us. and she's done well, with museui exons and prestious fellowips. but for her, too, the grant was something special. >> i thought maybe this is it!e maybe this is nonymous was a woman." wonderfully affirming t know that a group of art professionals really took a deep look at your work and wanted to say th you're on the right track and you're doing well. everyone has the moments ofor really wng alone, no matter how much support you have with galleries and curators and museums. it really esn't matter who you are. you always carry that with you. >> reporter: the life of an artist involves plenty of lf- questioning, siegel says, as well as taking risks with ideas she'll use this money to pay collaborats who'd gone withoutd pay or trarvices when she was low on funds. and to reinvest in materials to fuel the next series of pieces. that kind of investment-- in both materials and hope-- is exactly what susan unterberg intended when she began anonymous was a woman. there have bn improvements for women in the art world, she says, but not enough. >> women are not getting the shows they should be getting. >> reporter: and speaking out publicly seemed like a necessary next step. >> only 11% of art that's bought now that's pretty shockingists. because we think women are doing better and perhaps in some ways, they are. but it's a time where women need to speak out and we need to be heard and i need to have a voice in this conversation. >> reporter: at 78, her own work examines a difficult present-- the impact of climate change, an administration whose policies she opposes. and her hopes for won artists in the future? that these gatherings will be just as boisterous--ven as the need for her grant won't be as great. for the pbs newshour, i'm jeffrey brown in new york. >> woodruff: and we are surely and that's the newshour for now. but join us right back here at 11:00 pm eastern for special live coverage of results of the iowa caucuses.ju i' woodruff. and in the meantime, you can get the latest results online on our ghweb and social pages thrt the night. for all of us at the pbs newshour, thank you and see you soon. >> major funding for the pbs newshour has been provided by: journey along the mississippis river explore antebellum sights. civil war battlefields. american cruise lines fleet of small ships explore american landmarks, local cultures and calm waterways. relive history. american cruise lines, proud spsor of pbs newshour. >> fidelity investments. >> bnsf railway. >> consumer cellular. >> collette. >> and by the alfred psloan foundation. supporting science, technolo, and improved economic performance and financial literacy in the 21 century. >> supported by the john d. and catherine t. macarthur foundation. committed to building a more just, verdant and peaceful world. more information at macfound.org >> and with the ongoing support of these institutions >> this program was made possible by the corporation for public broadcasting. and by contributions to your pbs station from viewers like you. thank you. captioning sponsored by newshour productions, llc captioned by media access group at wgbh access.wgbh.org >> you're watching pbs. ♪ ♪ ♪ ♪ ♪ -today on "america's test kitchen," keith makes bridget the ultimate pork, fennel, and lemon ragu. jack challenges julia to a test taste of fontina cheese. and becky makes julia the perfect pasta alla norma. it's all coming up right here on "america's test kitchen."
