because now an tell a story about a shipwreck, which is an exciting one to te. >> woodruff: all that and more, on tight's pbs newshour. >> major funding for the pbs newshour has been provideby: ♪ ♪ moving our economy for 160 years. bnsf, the engine that connects us.me >> concellular understands that not everyone needs an unlimited wireless plan. our u.s.-based customer service reps can help you choose a plan

>> woodruff: a huge bill to fund nte federal government is now law, after presirump reluctantly got on board. he tweeted this morning that he might veto the measure. ithotals $1.3 trillion, wit big increases in military and domestic spending. he. trump ended up signing bill this afternoon, saying the military gains overrode thingsad thathim "unhappy." >> nobody read it. it's only hours old. some people don't even know-- $1.3 trillion, it's cond largest ever. it became so big because we need to takcare of our military. and because the democrats, who don't believe in that, added things that they wanted in ordeg their votes. >> woodruff: the president singled out the lack of re border wall funding that he wanted, and the lack of prottion for young, undocumented immigrants. he canceled the program that had

protected them, last fall. ume revolving door at the white house has turned again. this time, it ushered in president trump's third national security adviser in 14 months, the latest addition to a hawkish new lineup. the president left the white house late this aften for a weekend in florida, with nothing more to say about the latest riakeup in his national se team. as of april 9, h.r. mcmaster is out as national security adviser. .n. ambassador john bolton is in. >> it's always an honor to serve our country, and i think particularly in these times, internationally, it's a partular honor. so i'm still sort of getting used to itol >> woodruff:n becomes the third person in the post since presidentrump took office. the first choice, michael flynn, resigned just over three weeks after the inauguration, over

revelations that he had lied abou russian ambassador.he army lieutenant general mcmaster took over, but clashed with the president, who reporte complained about being lectured to, in lengthy briefings. mcmaster even drew a public presidential rebuke last month, after he said there was "incontrovertible" proof that russia interfered in the 2016 election. still, white house press secretary sarah sanders insisted only a week ago that he wasn't going anywhere.al >> gencmaster is a dedicated public servant, and hs is here, not f on the news stories that many of you are writing, but on some really big issues, things like north korea, things like russia, things like iran. >> woodruff: then came thursday evening's presidential tweet announng mcmaster's ouster. in it, mr. trump said the general, "has done an outstanding job and will always remain my friend." mcmaster, in turn, issued a

statement saying he now plans to retire from the army, and thanking the president for the opportunity to serve. his successor is a long-time hawk on foreign policy, who has served republican presidents r since ronagan, and has held president trump's ear as a commentator on fox news. john bolton was under-secretary of state for arms control under president george w. bush, and advocated for the invasion of iraq. hetoater served as ambassado the united nations, but only temporarily, as the refused to confi. his nominati more recently, he has argued for pre-emptive strikes against north korea. >> more diplomacy with north korea, more sanctions, whether against north korea, or an effort to apply sanctions against china, is just giving north korea re time to increase its nuclear arsenal. >> woodruff: bolton also cald for bombing iran, back in 2015, when the obama administration

was negotiing the nuclear agreement. since then, he has echoed mr. trump's desire to tear up the nuclear deal. >> i think the deal is inherently flawed. i think it's a strategic debacle for the u.s.ys you can alinker around the edges-- the question is whether putting lipstick on a pig is really going to make a difference here. >> woodruff: in addition, bolton has at times shared the president's skepticism about whether russia meddled in the16 lection. he once suggested the hack of mails at the democratic national committht have been staged, not by the russians, but by the obama ministration. >> it's not at all clear to me,e justng this from the outside, that this hacking into the d.n.c. and ter r.n.c. compwas not a false flag n eration. >> woodruff: bolter walked back those comments, and has often been vocal critic of ssia. but, he al video for a russian pro-gun

group supported by the n.r.a. on economic policy, he applauded the president's imporition of new s on china. his arrival comes just days after the president fired secretary of state rex tillerson, and named the more conservative c.i.a. director mike pompeo to replace him. in addition, the president's chief economic adviser and communications director announced this month that they are leaving the white house. for more on bolton's career and views, i'm joined by jonathan landay of reuters. he covered bolton's tenure at the state department during the george w. bush administration and the run-up to the iraq war. jonathan landay, thank you for being with us. so tell us more about who is john bolton? >> john bolton is a hawk. he espouses pretty belligerent views, and he has a history ofi being add outs the u.s.

intelligence community, which exists to this day where he has written about a significant violations by iran in the iran nuclear deal, whereas the man he's going to be working with, the director of national intelligence, dan coates, last month cold congress iran is abiding by the deal and the deal er working. mr. bolton had s clashes over u.s. intelligence where he was found to be exaggerating this intelligence, one of the incidents back in 2002, where he made a speech about cuba having what he said was developing offensive biological warfare program was disputed by two u.s. intelligence analysts, one attm the state dept, one at the c.i.a. both men and their bosses say mr. bolton tried to have them fired because of their arguments

with him over the -- his interpretati of the intelligence. >> woodruff: how did his relationship with the ecintelligence community a the role he played in the runup to the invasion, the war in iraql, >> wrom bolton was a major proponent of the invasion of iraq for -- because, you know, supporting the bush administration's contention that the late dictator saddam hussein had weapons of mass destruction. that case was based on bogus anx gerated intelligence, something i did extensive reporting with my repoing partner warren stroabl. but mr. bolton supported that case. at one point when he was up for confirmation hearings as u.n. ambassador, which he was never confirmed for, he was -- i believe there was a written questionnaire where he was asked if he had ever been iesvgated while at the state department. he said no, but it later emede

that, in fact, he was questioned by the state dep inspector general's office about the sources of intelligence at the the bush administration used for its case to invade iraq. >> woodruff: two other quick ings i want to ask you, jonathan landay, one has to do with arms antrol. how he dealt with arms control issues? we know that could well be an issue in the next year or s >> absolutely. mr. bolton has been a fairly strident opponent of many arms control agreements and, in particular, while he worked in the bush administration as the top arms control official at the state department, he was one of the ople who honchoed the bush administration, the united states' withdrawal of the anti-ballistic missile treaty with russia. >> woodruff: last t i want to ask is what happened ten years ago when george w. bush nominated him to be the ambassador of the u.n. very unusual, the republican majority foreign affairs

committee, foreign relations committee in the senate refused to confirm him, and there a wa lot of testimony about john bolton. just in a nutshell, what seppened is this. >> well, some of tases i just brought up came up. there was also alegations that he went after a formeru. a.i.d. contractor, a woman in moscow harassing her over apu business d while he was out of business government. >> woodruff: you don't mean sexual harassment >> no, nt all. it was a contractual dispute. the committee sent the nomination tohe senate floor, and he was not confirmed. he was put in the u.n. ambassador's job in what's known as a recess appointment. >> woodruff: all right, jonathan landay, a lot to learn, anthank you very much for talking to us. >> my pleasure. >> woodruff: we appreciate it.

>> woodruff: we return to the most recent shakeup by president trump of his national security leadership. what change will john botlon bring to the job of national security advisor? for that, we get two views.y naeldowney was a career foreign service officer. and ambassador.ed she sen the national security council staff during the clinton administration. she is now director of georgetown university's masterfo of science iign service program. and, matthew kroenig worked forh the office osecretary of defense during the bush and obama years, and at the c.i.a.of he is now a sor of government at georgetown university. >> reporter: and we welcome both of you to the "newshour". nancy mceldowney. to you first, what do you think of the choice of hn bolton for this job? >> i think john bolton is a

spectacularly bad choice for he is a hard-line nationalist. he is someone with disdain for diplomacy. he has -- is almost a knee-jerk advocate for war. whatever problem you look at from north korea ton even to russia, he's talked about war against all of tuhese contries. and when you look athi wte house that is already leaning in a very extreme direction with a president who seems inclined to make decisions that isolate the united states even further, john bolton is going to take us in the wrong direction. >> woodruff: matthew kroenig, what is your take on john bolton? >> first, i would like to thank h.r. mcmaster for his service to i think he was a very good public servant and national security advisor and i think bolton will be a very goo nationanational security advisor president trump. he has high-level experience att the state dent and at the u.n. he understands the national security challenges facinthe country as well as anyone else.

he has a good re the president, it seems, which is essential to be successful in th job, and hes good ties with the republican establishment, and they present an opportunity to heal so of the rifts in the party since the election, maybe bring in more traditional foreign policy hands into the process. so it's not getting the attention of some of the more negative coverage, but many republican foreign policy experts have been celebrating this appointment in the past 24 hours. >> woodruff: sounds like, nancy mceldowney, the two of you coming from very different places. >> yes. >> woodruff: why do you believe it's so bad given what mathew was just saying how he is more in the mainstream than people recognize. >> actually, i think he is so far from t mainstream, and i disagree both on policy but als on personality. we have seen bolton, for years, advocate the most extreme, the most militaristic positions possible, a preemptive strike against north korea, a

preemptive strike against iran, regime change in both countries, those areot things that are responsible policy course force our country to look a secondly, his personality. we can come back to this, but the role of the national security advisor is someone who is supposed to bring alicl poly options to the table. that is no john bolton, he is very argumentative, vindictive with those who disagree with him, and the reason he was never confirmed as bush's nominee to be the u.s tambassador e u.n. was because of republican opposition. >> woodruff: well, matthew kroenig, let's divide those in two.wi let's starh what nancy mceldowney is describing as someone who has advocated for a more militariestic and aggressive approach abroad. but you're saying that'sta right approach for this country? the use of force has been an

important tool of national diplomacy going back, military force contributes tolo dipcy. there's a bipartisan consensus in the united states that the united states needs to keep the litary option on the table for iran and for north korea. so i think it's good that we have a national securiwi advisor who'ing to consider all options to advance u.s. national security inerests. when it comes to his role as national security advisor, i think there are two models, historically. one is the honest broker model that scrokoff opted for bringing all options to the president, and the second model is the strategist roll henry kissinger played and i suspect bolton will be more in the strategist role of having strong opinions and i think which one works bt depends depends on the personalities involved and the needs of the president, so i think he can be successful in this role.

>> woouff: what about the idea, nancy mceldowney, he's going to havetrong opinions and that's what's needed now. >> i'm notv adocating people not stress a strong opinion, but having work security, the role of the person who whispers in the ear of the president,eho is th most intimate advisor when the president is ying to deliberate, we know the direction bolton is going to go in, don't have to speculate about what he's going to do in the future becausese we'v what he's done in the past. he was an ardent advocate for the iraq war. he still claims it was a brilliant decision. so i think people need to be w veried about the policy choices this national security is going to advocate for. >> woodruff: matthew kroenig, what about thal,t? >> wou know, i'm a political scientist by training. there's some good political science research on how advisors influence decisions of presidents and what political

scientists have found is that actually advisors are mostl influenten they argue against type. so that's why cin powell was central to debates over the iraq war, people saw him as aut us voice within the bush administration. so when he was even willing to advocate for the war, people took notice. >> woodruff: what are you saying that mea >> what that means for bolton is he's known for having tough views so i think when he argues for these tough-minded policies, that's not going to come as a mrprise. i think he'll bst influential when he argues for restraint, when eve bolton argues for restraint, that's when trump is going to take notice. >> woodruff: i want to ask both of you finally, of corse, it's john bolton national security advisor but there is going to be a new secretary of state. everybody assumes mike pompeo tets confirmed. what do you see ims of how the two of them work together, nancy mceldowney? it's clear to me what donald trump is doing is assembling a

war cabinet. he's got pompey o very much a hawk, made a numr of controversial statements while a member of coming and now coming in with a very sort ofan right-g, militaristic approach. bolton carrying the same message om the n..c. and i think, with those twoth taken to, we are in for a very bumpy rde,n though we have very seniors of ourmi tary from the secretary of defense, the chairman of the joint chiefs advocating in favor of different approach. >> woodruff: matthew kroenig, a war cabinet likely to take military action? >> well, part of the description there was a right-leaning cabinet and, yes, it is a right-leaning cabinet. there was election in the country and the republicans won, and,he republican officials. you know, the iran nuclear deal has been mentioned as one of the controversial issues that pompeo and bolton don't support, but that deal was increedably

controversial. bipartisan opposition, evere blican in congress and some democrats opposed it. nnly the obama administrat and their supporters supported it. so the idea that the trump administration is taking another look at this makes a lot of sense. so, again, controveial it seems in some circles but many conservative foreign policy experts i've talked to are excited about this cabinet, one of the maybe lrongest natio security cabinets we've had in some time. >> woodruff: we're going to watch it allol unf matthew kroenig, nancy mceldowney. we thank you both. >> thank you. >> woodruff: demonstrators from across the country will march against gun violence tomorrow, in cities from new york to l.a., chicago to atlanta, and smallwe towns in b. washington, d.c. will be where survivors of last month's deadly

school shooting in parkland, florida stage their "march forli ous" rally. john yang followed some of the students as they prepared for the big day. >> yang: 17-year-old high school shnior liz stout has visited her sister jenny in gton before, but this time is different. on valentine's day, liz was in her a.p. psychology class at parkland, flida's marjory stonan douglas high school when a teenager armed with an ar-15 assault style fle killed 17 of her schoolmates, teachers and administrators and woued 14 others. now she's in washington for tomorrow's anti-gun-violence "march for our lives." >> i've heard too oftethat 're too young to make a change. >> yang: she's haunted by what she saw in that classroom-- witnessing the death of fellow student carmen schentrup.

>> you know, i came to schoolt that day to education. my teacher opened up a lesson on personality, and next thing you know, we're crowded on top ofeh each otherd a desk, and we sn out and she's dead. and it's still, eving it still, talking about it, doesn't wrap around my head. but that's why i came up to d.c. because she deserved to live. >> yang: how are you doing? >> it's been rough getting a full night's sleep. i still can't finish a meal. because a part of me feels guilty running out of that room. i see a professional therapist, she's taught me methods, how to concentrate in class, when i get triggers, how to calm myself down, how to sleep better. >>maang: liz and her sister st a special op at the memorial to martin luther king >> even with m.l.k. and the cil rights movement, he wa known for making a big change, and it was the young people who started the movement.

and it's like today, the young people are comg out starting a movement. they're the reason why we're out here. they're the voices for the kids in chicago who don't have the same platform that we do. >> yang: from the ca all along pennsylvania avenue, organizers hope there will be about half a million people here tomorrow. in addition, there'll be similar demonstrations in about 800 cities around the nation and the world. what happened in parkland has turned thousands of students into activists-- including nate tinbite, who spoke at the capitol during last week's national school walkout. >> yang: the 15-year-old son of ethiopian immigrants, tinbite is a sophomore at john f. kennedy high school in washington's maryland suburbs. this week, he and his classmates made posters for the rally.y >>rents came from an education system not as remotely close to ours, or comparable to ours, yet theytill didn't have worry about their security

and safety.y and ould we? you know, our lives are definitely worth more than weapons that we see out here today. >> yang: the students leading tomorrow's rally are the foundation laid by groups like "moms demand action," formed aftethe 2012 sandy hook shooting. jennifer hoppe is the deputy director. >> we have bui up a grassroots army that really has the knowledge, the resources, and the tools that, that nowe are able to share all of those with students across the country. >> yang: for many kids in the nation's capital, the fight is personal-- friends and family have bn killed by gun violence. 17-year-old aaron king and his moth patricia reardon-king ma posters at a local community center. >> i lost a cousin, his name was kevin, to gun violence. he was simply trying to help a friend, but ended up losing his life simply trying to protect him. i just didn't want to see that see happening again.

bei know that it could hav me. so i said, enough is enough. >> you know, we don't want to s change tond amendment rights for individuals. e t we do want to kind of limit mber of guns that individuals can purchase, and make sure that students don't have easy access to guns. where there emotional. and they make rash decisions and effects other people's lives. >> yang: stoneman douglas students and activisid hogg and aalayah eastmond stopped by. >> this affects everyone, regardless of race, ethnicity, socioeconomic status oof the above. at the end of the day, we're all americans and we all bleed sam blood. some people have to live through this every day. that's unbelievable, and it's unacceptable. >> it feels empowering because douglas is predominantly white,c but there are kids there, obviously. so i didn't want anybody to feel likeyou know, only white kid are fighting for this. black students are fighting for it as well.a

>> yang: it'ght that's crossing generational, racial and economic lines. with teenagers leading the way, they hope to achieve real change where so many before thee have fshort. for the pbs newshour, i'm john yang in washington. >> woodruff: online, we will have coverage of the march throughout the weekend,rt including reg by members of our student reporting labs. that's at www.pbs.org/newshour. >> woodruff: we return to the white house, where the president left many people guessing if he would sign the massive spending bill, or if there would be any more high-level departures. yamiche alcindor is there to help make sense of these latesta twis turns. so, yamiche, the president said -- he tweeted this morning he's considering aeto, then he went ahead and signed it.

what was that all about? >> it's hard to say what motited president trump to threaten to veto this bill. political analysts say the president wanted to make conservatives who don't like this bill feel better about it by telling them that he s really disappointed and was reluctantly signing it. the president said he was signing it because of personal duty. heaid he felt a duty to keep america safe. he said the military fundingth e was going to ensure that america and the troops got the money that they needed, but it's also pretty clear that president ump didn't want to shut down the government. if he shut down the government and then he didn't sign this bill, it would have really been on him if the gnmovt shut down. congress tried really hard to keep this bill and get et through, so it would really have been a problem for him. >> woodruff: well,e kept us all dangling for several hours there this morning. yaache, the other thing it to ask you about is the changes at the white house, the surprise last night, the prsident

tweeted that h.r. mcmaster is out, he's bringing in john bolton. 've just been talking about mr. bolton here on the program. there ar other changes asell. this is just one of many. what do we know about theth president'king here? >> the president, at least from my sources, tell me he really wants to srround himself to people who are going to be loyal to him so as a result we've seen a lot of staff chae in. the last few weeks we've seen several people announce they were leaving, including communications director hope six, financial advisor gary cohn, personal assistant john mackenty, rex tillerson and h.r. mcmaster. republicans and democrats sayat hese people leaving makes this white house seem as though it's in chaos. >> woodruff: so, yamiche, the toone other thing i wanask you about is i guess what's been occupying a lot of news attention in the last few days,

an that is the fr ayboy model, karen mcdougall, she is one of three women suing president trump. she and another woman stormy daniels have said they had affairs with the president, and i want to show our audience just a quick, short portion of what nss mcdougall said lastght in an interview on cnn about her relationship with the president. >> after we had been intimate, he tried to pay me. i actually didn't ow how to take that. >> did he actually try to hand you money? h did. he did. and i said -- i mean, i just had this look of -- i don't know, just -- i don't e hen knowow to describe, the look on my face must have been so sad becau i've never been offered money like that before, number onemb two, i sought, does he think i'm in this for money or why i'm here tonight or this a normal thing? i don't know. but i looked at him and i said, that's not m i'm not that kind

of girl. and he said, oh. he said, yo're really special. i said, thank you. >> woodruff: yamiche, what else did ms. mcdougall have to sayo and what else cantell us about the lawsuits. >> hiss mcdougall said sh a 10-month affair with the president where they frequently had sex. she said she only brought up his wife melania trump once clling her intelligent. she said she broke it of because she felt guilty about him being married. he's one of three women involved in lawsuits concerning president trump apart from her lawsuit involving the "national enquirer" and her right to tell her ory. porn star stormy daniels also has a lawsuit. she wants to get out of an agreement where she would haeve toin quiet about her relationship with president trump. "apprentice" participant is suing president trump for defamation,, essentially, and said the president sexrually harassed he

while a participant at the show. >> woodruff: so much to kee t track ese days at the white house. yamiche alcindor. thank you very muh. >> thanks. >> woodruff: that brings us to the analysis and, to the analysis of shield and brooks that is syndicated columnist mark shiel, and "new york mes" columnist david brooks. i'm going back to what i was talking about earlier in the program, mark, and start with john bolton, the president making news on his tone tweeting last night the suris announcement that h.r. mcmaster was out, john bolton's in, andp this on s you just heard from yamiche, one change after another at this white house. what are we to make of this. >> is this first of all, i'd like tsociate myself with the remarks of nancy mceldowney who was on the show. i think she's absolutely right about john bolton. john bolton is not just ideologically fixed where he's been. unlike hissa parent foes within the strags, jim mattis, secrary of at the fence andn

joe rd, the chairman of the joint chiefs, he has never comforted anybody dying in battle. he's never written to a next of kin. he avoided military service himself, yet it's his prescription for virtually every situion that arises whether it's north korea o iraq, for aich he has never apologized, for which he wa relentless advocate, and wrong. so i just think, temperamentally, judy, he is the worst possible choice that donald trump could mae. he is brutal to people who work with him, and i just think what he is, he's a flatterer, and donald trump, we know, is incredibly susceptible to idattery. >> woodruff: dahat do you make not only of boltonuthe sequence of changes one right otter thher. >> first on bolton,

ideologically, trump should have picked him first. i think the president should have picked the sort person who shares their world view, and if there is anybody in the republican foreign policy galaxy that shares president trump's world view it's john bolton. in the administration, he was galking about america first lon before donald trump ever was. when he served in the earlier bush administration, he was a relentless foe of the republican establishment, the colin powells. he was relentless of the neoconservatives who believed in democracy and human right. he was an old style power vs. power kind of conservative. i agree with mark, he wasgh thof as a kiss up, kick down kind of guy. he famously was thought as someone who did no look at intelligence honestly but came with a highly ideological predispositionhe i don't thins the worst. he comes across are a bot ofes ishat i think will

increase a chaps of military action in north korea and iran.n he a goon, he just thinks we need to be more powerful than anybody else and threaten the power all the time, which when you combine it with a temperamentally unstable president, a dangerous combination. >> a dannagerous comon. i think david suffers from an excess of charity. i agree with his analysis up to a point. donald trump, if you recall, ran on a foreign policy all by himself, that he had opposed the war in iraq. that he was the only republican who had, just as barack obama was legitimately the only democrat in 2008 who had opposed the united states going into iraq, won the nomi and the presidency. i'm not saying it was the sole reason but certainle him a uniqueness and distinction he claimed for himself the evidence was not necessarily overelming that he had been

from the outset, but he's the opposite of bolton and trump nted a less assertive military presence, and i think the voices of restraint in this adminiration have been minished and i think it's down to mattis and dunford. >> i think it's far from a sure thing that it will be super bellicose, super mil the foreign policy bolton subscribes to goes back to ancient pre-world war ii hpublican history which is much moreeartland, much more isolationist, almost, but no sense of forelicy idealism, no sense of we want to make the world a better place or dignity or human rights. it's mucmore we're in a great power struggle and they're tough and we're tough and that's justh way they see the world. it's an old-fashioned, more, as i say, pre-cold war style republican foreign policy, but it did tend to be

non-adventurist. so there was some restraint even back in the earmly aerica first days. >> woodruff: so you don't see them being quick on the trigger? >> more than with h.r. mcmaster and rex tillerson, that's for sure, but not necessarily marching off to war. i do think trump's instinct is i don't pnt to send blood and treasure abroad. his cotituency does not wat to fight another war. i think he would be to commit troops aniy just by instinct. he's a domestic policy guy. >> john bolton's application for the job was h most recent piece in the "wall street journal" advocating e legal case for the united states attacking north korea preemptily and unilaterally. that is not pre-world warre ii ism, which was if anything isolationist. i mean, the national securityy, advisor, juas to be, to be successful, an honest broeeker bedefense and treury and

state and all the competing interests and present to th president the views and honest options that areed advocy his appointees. and the's noidence at all that john bolton is equipped temperamentally or experientially for that role. >>th totally agree hat, he does not fit this job at all. the one fear you woulddd is not so much what you believe buw rl of machismo. this is an administration whse masculinity is on high decibel while being very unstable. so the whipping up of the frenzy would be the part i would emphasize. >> woodruff: and you not only have all the changes, we heard yamiche talk about the lawsuits from these three womfen, two o whom say they had an affair with the president and they're filing suit for different reasons.

the third one having to do with something relayed, saying the president sexually orse har her physically and she's saying that she was described as not telling the truth and she said she's been defamed and sher suing that. ghmpleghme hnwhile, youave the a investigation going on. the president is roting out some of his lawyers. john dowd the lead lawyer is out with the russia case, investigation. other lawyers may or may not be coming in. jhow much pardy could the president be in when it comes to all of this? >> well, i honestly don't know, dy, how much legal jeopardy he's in. i'd say what he's finding out, the limation limitations of beig president -- i mean, when you're a billionaire in new york, real estate, and you've got somebody who's going to bring a charge against you, there are ways of dealing with that, whether it's through veiled threats or power talking to people omoney or

payoffs, and those arn't available to you as president in the same way. so you end up witmichael cohen, your attorney claiming ably it doesn't pass th sniff test, the smell test, the visibility laugh attest that hea up with $130,000 out of his own pocket and the goodness ofn his eart to get stormy daniels to drop any action or make anything public about her relationship with donald trump. i mean, you know, at some point in this whole drama, th religious right has to confront itself in the mirror and say, w you kno're not asking the , esident to be a paragon of personal behavit when his behavior apparently reaches the level of jus total dishonesty and deception and becomes a sham of the promises that he's made, then, you know, we have t

withdraw our support, and i just want to challenge theups, who besides jeff flake an joh mccain out of the hundreds of republicans on capitol hill is going to have the courage and integrity to stand up and take him on? >> i would have thought these evangelical trump supporters whowf left trump after the first six or seven deay sins and now we're up to 800. i'm not covinced anything will happen. maybe photographic evidence would change their minds.u ok at the polling when the access hollywood tape came out, trump support increased. it didn't go down because they fod themselves inibal war. the dowd resignation, that's a big event, because it really does signal -- dowd, one of the things, he wasooperating with mueller -- >> woodruff: lead lawyer. wd., john do he wanted to play professionally with mueller, and that's not going to go full-scale war. and his departure suggests

full-scale war or something cler to it is coming, and the republicans are going to have to think about that. and if there's an shred that if he fires mueller and we get into this full-scale battle, that they will separate thems dves frald trump, they better prepare themselves for that now because it's looking more likely today. >> he's right. at this point in the white house you need an i.d. card to say hello to cabinet meting or staff meeting, it's changing so fast. >> woodruff: or a name badge. a name badge. for donald trum said of british politician, he treats the truth like a second home, he doesn't live there all the time. we saw that on his idle threay tobout3vetoing the bill. we were told that general mcmaster was going to stay and then he's gone. we were toll as well wjohn dod and the legal team were in tact, and he's gone. and joe degeneva was coming in and now he's not.

at this point, there has to be total chaos there. >> woodruff:where do we lok, david, 15 seconds, for stability in this white hou tse? chaos is the stability. it's in the president himself. he's going tbe like this as long as he's there. >> woouff: all right. ow! >> woodruff: we heard it here. david brooks, mark shields, thank you both. >> woodruff: finally tonight, ooe second in our two-part at how cutting-edge imagery is helping scientists to preserve centuries-old shipwrecks. last night, we took you bermuda, where more than 300 ships have wrecked over the st 400 years. tonight, jeffrey brown travels to san die, as part of his ongoing series, "culture at risk."

>> so, welcome to one of our walk-in virtual reality environmts. >> brown: it's meant to transport you across space and time. >> it's the world's highest resolution virtual reality environment. it's running at 500 megapixels, half a gigapixels worth of resolution. >> brown: called the "sun cave," it's an immersive, sci-fi-like wond-- hard to fully convey television-- driven by the latest advances in computer visualization and 3d imaging. >> so, it really gives us a mechanism to deliver, visually, very compelling representations of that environment. >> brown: it's all part of a project overseen by faulko kuester, a german-born professor of structural engineering at the university of california, san diego, one that puts high tech to work on behalf of cultural preservation. >> virtual reality is a very powerful mechanism that allows t explore spaces, and environments, and scale, but one our ows, in a controlled and safe environment.so

and it becamwhat natural to think about how we can actually create a future for the orst. >> brown: a futurehe past? >> yes, can we make sure that d?rld heritage gets preser >> brown: all around the lab, the tools of the trade:gn specially-de drones and cameras, computer visualization programs, 3d printers, and the recreations made from them. it's an effort that volves scientists, engineers, archaeologists, and t historians, documenting and analyzing historic sites and artifacts around the globe >> so what we have here is a quarter-scale replica of leonardo da vinci's adoration of the magi. our research team had the opportunity to actually work very closely, intimately, with this painting. >> brown: after scanning the original, kuester's team created a digital da vinci, allowing a whole new way to interact with the painting.

we can actually, and it's thesez amg stories which suddenly unfold, which make it exciting for the younger generation to actually interact with it. you can become the explorer. tell me what's really happening on that staircase. can we peel away the pigment,to which the curar really wouldn't want you to do. eg brown: the san diego team has also visited and to digitally document sites as diverse as mayan ca,es in guatemnd the baptistry of san giovanni and adjacent duomo cathedral in florence, highlighting areasdef aging and rioration. but last march, the team decided to go deeper-- much deeper-- and launched an ambitious project to virtually cataloe 100 underwater shipwrecks in bermuda, an island that has a history of wrecks dating back more than four centuries. >> what bermuda has given us is

the ability to become aquanautsx orers under the water. >> brown: because everyone is interested in a shipwreck. >> right, that area truly a treasure trove of wrecks. hi brown: kuester teamed up with marine scientistppe rouja, bermuda's "custodian of historic shipwrecks," who's been ving and documenting these underwater sites for years. >> it's not just the tragedy. i think it's the investment, you know, what a ship is and what it actually represents, and thloss of that, and then t romance of it sitting on the bottom and being this time capsule. >> brown: the project, called is currently100," re-examining a pair of the island's most famous shipwrecks; e "montana" and "mary- celestia," two confederate blockade runners sunk in 1863

and '64. >> blockade runners have this mystique about them, because they are this tool that was esseially used to run goods into the confederate south during the civil war, the u. civil war. >> brown: over the last year, rouja has sent keuster hundreds of thousands ostill images and deos shot underwater, capturing these wrecks from every conceivable angle. >> suddenly, we're diving on wrecks we've dove onor 30 years and it's like you're diving it for the first time. "oh, wow. i really want to capture that. oh, did you see the door? yeah, let's get a closeup oft. that p >> brown: back in san diego, the team uses the data to digitally recreate the ships. >> what is left, what is its state of health. how is it decaying? what other artifacts are there? now we can tell a story about a shipwreck. >> brown: keuster is also keeping track of every artifact rouja finds. >> we see actually a masonic jar that was found on one of the

shipwrecks. and interestingly enough, these were truly priceless artifacts. they were as valuable filled as they were empty, and they were actually being shipped back and forth to be refilled. b >>wn: the result: three-l dimensionadels and videos that allow researchers and amateurs alike to visit the sites from their own computersic and mobile d-- no wetsuit required. >> we actually have seen many of the sites inays nobody else er has. >> brown: the model shows the "mary-celestianow rests on a flat, sandy seabed just 600 yards off bermuda's south coast. at the "montana," it bomes clear how wrecks become part of the marine habitat, allowing scientists more compive data on the current health of bermuda's coral reefs and fish populations. >> we're not just cataloging the wreck.

you're actlly capturing data that people didn't even know they were collecting. t u start to learn things about sea level rise, abastal change. all these things suddenly come into play in ways that i never imagined. >> brown: that's the hope with the bermudproject-- to explore and preserve in new ways going forward. and keuster and his team are thinking far beyond these wate, hoping to replicate th work in ever greater scale. for the pbs newshour, i'm jeffrey brown from bermuda and san diego. >> woodruff: tomorrow's edition of pbs newshekend will have full coverage of the students march to protest gun violence. and that is the newshour for tonight. i'm judy woodruff. have a great weekend. thank you, and good night. >> major funding for the pbs newshour has beeprovided by: >> bnsf ilway.
