deadlocked jury. cosby walked slowly as he left philadelphia, still free on $1 million bail until sentencing. after the verdict, districtat torney kevin steele said cosby had preyed on women for decades. >> he used his celebrity, he used his wealth, he used his network of supporters to help conceal his crimes. and now we really know who was behind that act, who the real >>ll cosby was. ang: delores troiani is andrea constand's attroney. >> i want to express on behalf, if can, the gratitude of s many women who admire andrea for her courage. she came here 14 years ago for justice. i am so happy today that i can say that although justice wa delayed, it was not denied. >> yang: cosby did not speak to reporters outside the courthouse but his lawyer, tom mesereau, did briefly. >> we are very disappointed by de verdict. 't think mr. cosby is

e ilty of anything. thght is not over. thank you. >> are you going to appeal? >> yes. yes, very strongly. >> yang: for more on the drama t the courtroom today and for the la weeks, we're joined by manuel roig-franzia of the "washington post," who is outside the courthouse. we should note that mr. cosby used a vulgarity in the court which we'll quote. manuel, tell us a little bit about the drama of the verdict. >> i was an intensely emotional moment when the verdict was read. you heard an eruption of sobbing room.the back of the court those were two women who have accused bill cosbyf sexual assault but were not testifying. they were taken from the courtrym, but even when t were outside in the hallway, you could hear crying filtering through these big, heavy doors that lead into the room. >> yang: how does cosby react? >> cosby initially was stone

faced, but you couls see t weariness, this defeat on his face. this is man who is 80 years old. he showed incredible stamina throughout the whole tal. but his eyes looked heavy, the lids heavyn them, and his face looked a little sunkennen he stayed ridgedt that moment. but when the jury left, he erupted. he erupted at t district attorney, kevin steele, aggesting that he might be a flight ris he just yelled out, as you said, telling him, i don't have a private plan and he doesn't know. >> yang: he use aittle stronger language than that, didn't he? >> he certainly did. it jarred the courtroom. they hadn't seen that kind of an outburst from bill cosby throughout this entire trial, ignificannk it's that the jury was not there to see this. the jury had left.th had made their decision.

and now he was face to face with the men who want to put him onin prpossibly for the rest of his life. he yang: those are t prosecutors. you covered both trials, manuel. how did this retrial differ from the first trial? >> there was one huge difference. in the first trial the judge only allowed one previous accusedd a --user to testify. this time around the judge allowed the prosecution to call five difrent women who have accused cosby of drugging them and in four cases of sexually assaulting them over the years, from the 1980s until the 2004, when andrea constand made h allegation of sexual assault. and these women testifying on sne stand have something of a ball effect. it gave a lot of momentum to the prosecution and they were able to leverage, that showing the jury thaty bill co was not just being accused by andrea

constand in this complicated scenario in 2004, but that he had a pattern ofav bor that was similar and consistent for decades. >> yang: was there any difference in the defense the two cases, in the two trials? >> big difference in the defense strategy. in the firsthe trial, bill cosby was represented by brian mcmonogal, a philadelphia idtorney, the defense was built around thi that bill cosby and andrea constand were having a love affair. this time around it was a much dark, much rougher defense. the defense was built around the idea that andrea nstand was a con artist, that she had targeted cos as somebody that was wealthy, that she was madly in love with his money and his fame, and that she executed this plan to extort money from bill cosby, and the evidence of thata d lawsuit that she filed and

settr $3.4 million. i think one of the problems with that approach is that andrea constand came off on the stand as aaiomewhat, confused person, and she did not seem like the calculating sort of schemer who could have pulled one over on a wealthy man who was surrounded by powerful and aggressive attorneys, public relations agents, and other members of his entourage whd were shiing him. >> yang: very quickly, manuel, what do we know aoub sentencing? >> sentencing is expected within 60 to 90 days. bill cosby is being required to stay at his house at elkins para nofrom here, and he could face a maximum 306 years in prison, which for man at the age of 80 is essentially a life sentence. >> yang: manuel roig-franzia of the "washington post," thanks so much. >>you're welcome. >> yang: today's verdict

represents a collision of two icltural forces: the breakthrough a-american entertainer who starred in the anmily-oriented cosby show of the late '80early '90s, and the first high-profile trial of the me too movement. to examine that, we're joined by soraya mcdonald, culture critic for the soraya, thanks so much for joining us. this is... between the deadlocked trial of the first trial and today's conviction of course was the "me too" movement. do you think that had an effect on the jury? >> i do. and i think what the effect of the "me too" movement was was that for years we have bee llaring so many stories from osby's accusers. we saw 35 womenictured on the cover of new york magazine wit very similar stories. and the response that people kept giving was, why didn't these women come forward earlier? why did they wait so long?

there wasnt nearly the understanding of power dynamics and just how much control bill ntsby could exude, like within the tainment tonight" industry, and then when you saw this story happening over and over and over again with different powerl men starting with harvey weinstein and then charlie rose and matt lauer and all of these other high-profile men being accused of sexua harassment or sexual assault that had gone o for decades without the general public knowing about it, that definitely provided a really significant shock to people's understanding of sexual assault d sexual harassment and how victims process certain anperiences an how long it take sometimes for people to come forward. >> yang: do you think this

will embolden and encourage more women to speak up? >> i think it will, because it soys that there are consequences for this of behavior and there are legal and criminal consequences for this sort of behavior. one of the things that we know about rape and sexual assault is thatt is severely underreported, and part of the reason for thats because the conviction rate is so low and because these trials can be such a horrible ordeal for so many survivors, because they are asked to relive not only some of hee worst moments of their lives, butre subject to cross-examination, and that can be a really rough when you're being told that you're a liar, that you're doing this to be self-serving, thch you're in sef money or fame when all you're trying to pursue is some msure of justice. >> yang: soraya, also the

coage of bily himself, someone who had this very wholesome image, was something of a public moralizer for a while. what's the impact on this cultural moment of now having him convid? >> well, i think the cultural impact is that going forward we're going to be looking at our icons with maybe a little more scepticism than we normally would. you know, part of the tragedy o thide from the way so many of the women's lives have been upended by this man's actions, is that there's a great dealf disappointment for a lot of people who thought of bill cosby as america's dad, and that's really understandable. and so in processing that, i think we have to look at how much power and influence, you know, we ascbe to any one

person, because part of that can contribute to this ultimate sort of betrayal and t downfat we're seeing now. >> yang: soraya mcdonald, anks so much for joining us. >> thank you for having me. >> yang: in the day's other nen,, the white house physic navy vice admiral ronny jackson, withdrew as nominee for ovcretary of veterans affairs. he denied that h- prescribed drugs or crashed a vehicle when he waaidrunk, but hethe accusations had become a distraction. asrse marked "take our daugh and sons to work day" in the rose garden, president trump defended jackson. > he's a great man, and he got treated very, veunfairly. he got treated really unfairly. he's a hell of a man. >> yang: the president blamed montana senator jon tester, the ranking decrat on the veterans affairs committee. he'd publicly detailed the allegations againsjackson. tester is up for re-election, and the president warned that he "has to have a big price to pay. the embattled head of the environmental protectiongency

today rejected questions about his ethics, calling them "half- truths" and "twisted" claims. at a pair of houseearings, scott pruitt said critics of his security spending, condo lease and luxury travel are just trying to undermine the trump haenda. we'l a full report, later in the program. outgoing c.i.a. director mike pompeo won senate confirmation today to be secretary of state. the 57 to 42 vote was largely along party lines, with six democrats and independent angus king of maine joining all the tepublicans voting. a quick swearing-in, he headed to brussels, for a meeting of nato foreign ministers, and then on to the middle east. pompeo succeeds rex tillerson, who was fired by president trump last month. president trump will travel to britain in july, and meet with prime minister there. the white house said it will be a working visit. aere've been concerns tha full-blown state visit would draw huge protests. mr. trp cancelled a trip to london earlier this year.

a so-called ravan of asylum- seeking central americans has arrived at the u.s.- mexican border. nearly 200 people, mostly women and children, are now waitg in shelters in tijuana, with more expected in the annual mass migration. at a house hearing today, homeland security secretary kirstjen nielsen warned agl nst iy illetry. >> beia caravan does not give you any additional legal rights. if you illegally enter our country, you will be referred for prosecution. if you file a false asylum claim, you will be referred for osecution. if you aid or abet or coach someone on how to break our l you also will be referred for omosecution. >> yang:of the migrants say they plan to try to enter the united states on sunday, at the border crossing at san diego. another group of immigrants in the united states has lost temporary protected status. today the trump administration terminated protectio some 9,000 nepalese.

they've been allowed to stay in the u.s. since a 2015 earthquake vevastated their country. now, they ne year to leave. similar protections already udded for thousands of nicaraguans,ese, haitians td salvadorans. tens of thousands chers in arizona staged a statewide strike today, for better pay and ucation funding. in phoenix, teachers and supporters lined street corners, then mahed to the state capitol. the scene was similar in denver, where teache rallied on the eps of the colorado capitol, in the first of a two-day protest. the u.s. senate ethimittee today severely admonished new jersey democrat bob menendez. the panel said he violated federal law and senate rules by taking giftsrom a florida doctor, failing to report them, and using his senate office to assist the doctor's interests. ianendez's federal corruption last year ended in a mistrial, and the charges were later dropped. in boston, they're changing the name of yawkey way, outside

fenway park, because it honors a man accused of being racist. tom yawkey owned the boston red sox for more than 40 years. but his club was the last in the major leagues to field a black player. today, the city's public improvement commission voted to return yawkey way to it's original name, jersey street. and on wall street, the market mostly advanced as tech stocks rallied and interest rates dosed. thjones industrial average gained 238 points to close at 24,322. the nasdaq rose 115 points, and ne s&p 500 added 27. still to come on tshour: lawmakers grill embattled e.p.a. chief scott pruitt what to expect ahead o historic summit between north and south korea, and much more. >> yang: president trump started

his day on the phone, calling into what seems to be his favorite sw, "fox and friends." the president sounded off on all sorts of this, from the investigation into his personal attorney and the activities of the justice department. here to walk us through what the prident said is our white house correspondent yamiche alcindor. quite a way to start morning, yamiche. >> this was a pretty long phone call from the president. he talked about hillary clinton in the election. he sounded like he could have talked for several hours. at one point the fox ws host asked the president about his personal lawyer, michael cohen. cohen recently said he would ilead the fifth in a law filed against the president filed by porn star stormy daniels. this morning trump seemed toim distancelf for cohen. >> well, as a percentage of my erall legal work, a tiny settle fraction, but my goal would repr me and represent me on some things. he represents me like with this crazy stormy daniels deal. he represented me, and i hope he's in great shape.

but he's got businesses, and his lawyers probably told him to do that. but i'm not involved, and i not involved. and i've been told i'm not >> this was rally important, because the president's words were used against michael cohen today. e lawyers for the federal prosecution, which of course affect criminal casenvolving michael cohen where he's being accused of bank fraud, they wrote a letter to the judgeth saying, look president is saying that he only did a little bit of work -- that michael cohen only did a littlbit of work for him and we should be able to see these documents and there isn't that much privilege, and the judge said there would be a spel aster. this is seen by legal experts as prgood win, because the ident's lawyers and michael cohen's lawyers wanted an independent person to go through all those doments that were seized during that raid, so it's in some ways a win-win, but the other problem is the president is out he talking. he's out here giving these interviews, and that's michael coheno because he's contradicted him on all sorts of things.

legal experts tell me if they had a client like president trump, they would be in real problems because you want someone who will control your client and not contra somebody that's involved in a federal investigation. yang: and it didn't end there. there was more. >> ys, the president took aim, he often does, at the justice department. he hinted that he might take a re active role in the agency's investigation. >> i'm very disappointed in my justice department, but because of the fact that it's going on, and i think you'll understand this, i have decided that i won't be involved. i may changemy mind aome point, because what's going on ns a disgrace. it's absolute disgrace. >> now, again, this is kind of typical of the psesident. we'v him talk about the f.b.i., especially the top tier of the f.b.i., saying they are crooked, that they're corrupt, that they're out to get him, there's a witch-hunt but it's important that the president is saying, i high take a more active rol h that mea could maybe fire robert mueller.

that means he could maybe fire other ople some people are very worried, and the legal experts say we should watch for things like this because it tuld be crumbs te's leaving for what he could do. but to turn bacto stormy daniels and her lawyer, he was really happy. he said this is stunning prat ident trump is out here giving these interview, talking about these things. he sasd it's making their stronger and stronger by the day, so it's really proble lmat, st that's what legal experts tell me. >> yang: the opposi lawyers are happy. what about the white house lawyers? what about trump's lawyers? >> from the white house perspective, they said you have to go to the personal lawyers. they want nothing to do with this. trump's personal lawyer has been very, very tight-eplipped. n ryan said he was okay with the special master, that he s a fine pick. she's a retired federal judge. they're not upset about that. but a lot of people are not talking. i talked to so many or tried to talk tso many lawyers or secretaries and pr people, and no one wanted to talk about this. that probably goes back to the idea that the president ison

sothat's hard to control and his lawyers are trying to figure out whato say when he's giving 15-minute-long interviews to "fox and friends." >> yang: white house correspondent yamiche alcindor, thanks very much. >> yang: now, we turn to one of the president's top cabinet members who's been under fire himself: e.p.a. administrator scott pruitt. his appearances before two house committees today were ostensibly about budget matters. but lawmakers put him on the hot seat for all sorts of different reasons. in a moment, jeffrey brown talks with lisa desjardins about the politics and the policy at issue. but we begin with lisa's look at pruitt's day on capitol hill. >> desjardins: long a lightning rod on environmental policy, this was e.p.a. chief scott pruitt first chance to address a recent slew of scandals with congress.

he insisted those were distractions and has nothing to hide. >> i'm here and i welcome the chance to be here to set the record straight in these areas. let's have no illusions to what is really going on here. those who have attacked the e.p.a. and attacked me are doing so because they want to attack and derail the president's agenda and undermine tons administra priorities. >> desjardins: pruitt is under at least ten investigations, one questioning large raises for two gaffers, several on spend for personal security, luxury travel and thousands on office upgrades another about his $50 a night lease of a condo from the wife of an energy lbyist. and retribution questions-- some ngp.a. employees who criticized the spenave reportedly been demoted or forced to change pubs. icans on the committee, like greg harper, largely defended pruitt by letting him defend himself. >> will you explain these allegations and tell us what steps e.p.a. takes tig invee allegations brought forward by epa employees? >> first, there's no truth to

the assertion that decisions have been made about reassignment or otherwise in terms of employment status based upon the things that you reference. >> desjardins: from reoribution to fism. democrat paul tonko pushed tt on large raises for t longtime aides. >> this is your opportunity to set the record straight. >> desjardins: pruitt denied approving the raises in a fox ews interview this month, but staffers ails have indicated otherwise. today pruitt implied he did know. >> congressman i was not aware of the amount nor was i-- >> not the amount, were you aware of the raises? >> desjardins: democrat peter welch pressed pruitt on his $43,000 classified phone booth. pruitt said he asked for the booth but never approved that much spending. >> not right close to my office >> pardon me? >> they're not right close to my offi. >> how often do you need to use your secret phone booth? >> it's for confidential occasions and its rare.

>> on those rare occasions, is it too much to ask you to walk whatever distance it takes? >> it depends on the nature of thllcall and how urgent the is. >> the point is you have two locations you can go to when you have to make those phone calls. tis is taxpayer money. itpayer money. >> desjardins: many republicans thanked pruitt for rolling back l gulations they see as onerous, and seveiticized democrats' questions. >> if you can't deba policies you attack the personalities end that is hag to you. >> desjardins: there were policy questions, including about a rule pruitt proposed this week tat would require scientists to turn over their raw data in pertinent studies. democrats say much of that data is confidential medical and personal information. republican kevin cramer defended we idea. re not asking for personal ncta, we're asking simply for

the scto be revealed, right. i mean you can protect personal data, right? >> both the personal data as well as confidential business information. >> desjardins: president trump has trumpeted his support for lyuitt in the past, especi his deregulation efforts. but the white house has been more cautious lately press secretary sarah huckabee sanders incated the administration takes the pruitt questions seriouy. >> again we are evaluating these concerns and we expect the administrator to answer for them. >> desjardins: in today's hearing retiring republican house member ryan costello said the answers so far are not enough. >> i've reviewed your answers and i find some of them lacking or insufficient and i believe nsu've demonstrated, or you've not deated the requisite angree of good judgement required o appointed executive branch official on some of these spending items. >> desjardins: pruitt today insisted most spending decisions were made for security reasons

or without his specific knowledge. >> brown: during the afternoon, pruitt appeared before a second committee and once again, he made fewoncessions about the decisions in question. the day was seen by some as a spivotal moment for pruit future. lisa desjardins joins me now. i want the talk first taout environmpolicy, right, which was clearly part of that. lurking in the background is the changen of how much scott pruitt has brought. >> he's brought significant change. he has 22 major deregulatory actions that he'ser en. the waters of the u.s., that's something congress helped roll bae. it was a hiece of kind of water environmental law from the obama presidency, which isow pushed back five years, in addition to clean power plant is something thatwas repealed, i think there are real questions about how long all of theseon acwill last, because they have happened so quickly. many are facing serious court allenges. there are other things like fuel

efficiency that he is deciding now. >> brown: he's getting pushed hack all over the place. >>s right. from conservatives he's getting support, but there are real questions in the court. >> brown: u referred in your piece to a proposed rule that he put in requiring scien to turn over raw data too studies. he refers to it as transparency hin science. also likes to talk about secret science. ais is a rule he put on the table two da. it is incredibly significant. what this ruled would mean is that any -- the phrasing is s ivotal regulatory science," thatience that the administration uses to base new les on, must have all the data made public. >> brown: the raw data. >> the raw data. he says scientists have an agenda. he wants to get down to the facts, he says,ri however,cs point out there are many problems with this. one, not only would this mean fewer studies, because they rely er confidential data, but it would mean f regulations, and that's what critics say is

the real agenda here. look who supports th rule, you're looking at the fossil fuel industry and also at conservatives in general who have business interests. critics say that's a real factor. now, can they mask this data as irpruitt suggested in t piece? scientists say no. this is a time when data itself is a huge commodity and there wi be fewer programmers oiguring out how to get it. >> brown: but this to a much larger question about this ieministration's relationship to e and scientists. >> that's right. this is man who says he does not trust science and he's someont who thinks te is a lawyer who is not a scientist. this needs to be more of a business-like agency. >> brown: now, while everybody was watching that hearing, what about the president and the white house at this point? what signals are they senng about scott pruitt? >> i'm watching my twitter feed right now.s you know, it significant that this is when the president's first nominee, it's probably the cabinet member that he says the

cast positive things about. >> brown: se of those regulations. e because of those regulations and beca hears when he goes out to the rest of the country, some trump suppo,te that they love this man. it's significant that with all those fact joerg the white house is this week being very cautious and waiting to see how the cards play. i think they just aren't sure with all of these investigations if this is someone that they can support long term, and day to day we just don't know,. >> brown: so on this day, you look at the hearing, you think thout what you just said with president, weighing the various many possible questions and scanngals, weighihe policy questions, what picture emerged? >> watching the many hours of hearings, this is man who was poised. he answered questions politely. but when repeatedly asked about these many investigations never took personal responsibility for any of the elements in them. he repeatedly said these were lyaff errors. occasione did say he's

made changes, like his travel. he no loer takes first-class flights. but he has said he did that originally because of asecurity recommendation. again, he does not feel personally responsible for these oblems. instead this is man who feels he's under attack, and he says it's political. ins critics say he's the political one launthe attack. >> brown: you're watching this minute by minute, and day by day for next action. >> that's right. i think for next few weeks. w, congress is gone next week, so that helps him out. thoc won't be rheting opinions for the time being, but there will be more investigative reports coming out. >> brown: more to come. lisa desjardins, thank you. >> my pleasure. >> yang: stay with us, coming up on the newshour: the harrowing plight of young rohingya girls being recruited into the bangladeshi sex trade. and as the value of digital currencies continue to climb, paul solman explores if there is

a bitcn bubble. in just a fehours' time, a historic meeting will take place between north korea's dictator kim jong-un and south korean president moon jae-in. the two wi discuss the north's nuclear program, begin talks on officially ending the korean war after 65 years, and lay the groundwork for a meeting between ism and president trump later pring. as special correspondent katrina yu reports, while the world looks on, no one is more anxious about the results of tomorrow's summit than koreans themselves. ul reporter: from her room in the suburbs of snorth korean native kim ryen-hui has been counting down the days to the summit. oue has been living in the for seven years. she sees tomorrow's meeting as bringing her one step closer to being united with her family in pyongyang. >> ( translated ): now we can finally overcome the pain of the division. as a child of the north korean

nation i'm so happy i can now tell my child the time for reunification is comg. >> reporter: kim is one of many north koreans separated from loved ones across the border, ret unlike most defectors, she's not happy to be the 49-year-old says she was n icked into thinking she could work temporarily iuth korea, and hasn't been allowed to return to her daughter. hi ( translated ): i'm a mother of a. people tell me the south is a decent place to live, you won't starve here, you can live well. and ask why would i go through the hardship of returning to the north? but even if i can't eat or live well, if i could be with my family, just hold my daughter again, there's nothing else i would want. >> reporter: it's not known whether the issue of family separation will be on the table when the two leaders meet, but for the first summit in more than 10 years, an agenda is clear. >> ( translated ): we must create a clear path that leads to the denuclearization of the korean peninsula, the establishment of perma ant peace, the development of sustainable south and north korean relions.

>> reporter: the meeting will be held at peace house in panmunjeom, a border village erside the demilitarized zone the korean war armistice was signed in 1953. a few miles away, soreans have been flocking to their side of the d.m.z., excitg ent replacine tension of late last year. the heavily fortified stretch of land was, until recently, blasting loudspeakers into the north. earlier this week south korea suspended their propaganda broadcasts from the d.m.z. as a gesture of goodwill inhe lead- up to the summit. normally comprised of south korean pop, radio dramas and news, they were designed to show north koreans how much the world had moved on, and how better life in south korea is. changes followed the mos significant gesture from the north to date, an announcement last week that the regime woul suspend nuclear tests and focus on the economy. >> ( translated ): as long as

there is no nuclear threat and provocation against our nation, we will never use nuclear weapons and under any circumstances we will not transfer our nuclear weapons and nuclear tenology. >> reporter: but many, including activist lee min-bok, believe north korea cannot be trusted. >> ( translated ): it's not because of south korea's efforts, or because of kim jong- un's good will. this summit has arisen because of the great external pressure n t on north korea. as s this pressure is gone, they'll will cheat us again. >> reporter: the defector made two attempts to escape the north orbefore arriving in south in 1995. he's now devoted his life to floating balloons carrying leaflets across the border, weapons in a war for the hearts and minds of the north korean people, he says. critics say his work is useless, but he points to attempts on his life by the regime as proof ofim ct. leaflets are, after all, the reasone's here. >> ( translated ): this is the

ebest method, this what i realized. n.fore i was perfectly devoted north korea citi didn't drink, didn't smoke, or chase girls. i only did what the leader and the party said i needed to do for my country. but after finding one leaflet i vearned of the fraudulent goment and i went from one extreme to the other. >> reporter: in seoul many others are also wary of the regime's promis. >> ( translated ): the point of the summit this week is denuclearization. but north korea won't give up its weapons so easily. ( translated ): denuclearization is isn't simple or straightforward, and it won't be fast. >> reporter: kim ahra fled to >> reporter: although professor ark inhwi says north korea has lied over and ovin, he has reason for hope, thanks in part to what he calls the trump effect. >> ( translated ): trump's administration is very military oriented and strong regarding the korean issue. >> reporter: for many the inter- korean meeting is simply a

preview of what's to come. for most south koreans the real test as to whether the situation with the north will change will be seen after the planned meeting between president trump and kim-jong-un seoul says washington will be kept closely informed of friday's developments, with a phone call from south korea to the white house planned right after the meeting. the topic, no doubt: howsho turn ant-term wins into long- s rm results. for the pbwshour, i'm katrina yu in seoul. s yang: we want to tell you up front: txt story is not suitable for children. , your kids are in the ro please turn us off and come back in about 8.5 minutes when paul solman helps make sense of what some call the "bitcoin bubble." even for adults this is a disturbing story, but an important one.

>> reporter: he says the easiest way to get the girls is to prey on their vulnerability. >> ( translated ): when the rohingya girls arrive in bangladesh, they don't know anything. they are so innocent, scared, and unaware. i tell these little girls, look eeu have nobody, i'll marry you, but wemoney to get married. rohingya girls are easy to convince. i have sex with all my girls, i take their virginity. then i share them with the clients. >> reporter: what sort o clientele visit these girls, are they bangladeshi men, who are they? >> ( translated ): most of the ients are bangladeshi tourists, but about once or twice month i have foreigners, igite men, americans, europeans. they stay in the b hotels and keep the girls for two to three days. i don't speak directly to the white men, ually a hotel nager calls me and asks me to send over photos, they a the liaison. >> reporter: many rohingya women who fled violence end up in

desperate situations, both inside and outside the camps. reeir precarious circumstances make them easyto those that seek to exploit them. tafor the pbs newshour, i'a rashid in cox's bazar, bangladesh. >> yang: economics correspondent paul solman has beenng into cryptocurrencies for us, most recently, trying to explain what they are and how to buy them. tonight he looks at whether the s e of bitcoin is a bubble? this story ipart of his weekly making sen$e series. o' reporter: back when mexicali burritdavid zimel first accepted bitcoin a few years ago, it was worth, well, about the price of a burrito. >> i think we had two sales. >> reporter: two sales? >> i think we ended up with about nine bitcoins. and we just kept on pushing.

we wanted to turn it into real we wanted to turn it int real cash and we finally did. i wish we would've held on to it a little longer cause ld have been worth a few thousand dollars. >> reporter: make that $80,000 as i record, though by the time you see or hear this, who knows? >> you're going to get0016 bitcoin. >> reporter: i'd bought my first 16 ten-thousandths of a bitcoin that very morning for $20 when the price of a whole "coin" was $8600. i wound up with a princely $13 dollars and 82 cents worth after knavish transaction fees. if i wanted to use it here now to buy a burrito. yes? no? >> no, we have no idea what to do with it. ewouldn't have any idea on how hange it or what it's worth. >> reporter: no wonder. when zimel cashed in his bitcoins, they were worth just a few bucks. last december, the price h nearly $20,000, plunged by two thirds, is now up again by half. so, how can it be a currency if you never know its current

value? >> it is developing many of the qualities of currencies but it isn't yet filling the basic role of a currency which is to enable transactions. >> reporter: professor, author and hedge fund manager vikram mansharamani. >> you do need some more stability in the value of it before it gets truly adopted as a currency, not as an instrume. of speculati today it's de facto an instrument of speculation or a means through which to fund illicit activities off the grid. bitcoins and sort of other cryptocurrencies live outside of the traditional banking network. and in fact are intended tdo so by design >> reporter: that's why the newshour wouldn't accept a sttcoin donation in 2013, when ies abounded about its use on the so-called dark web, to buy drugs, guns, and sex. but local restaurants like veggie galaxy in cambridge that used to take bitcoin don't any re because the value fluctuates too much, plus it's too cumbersome for petty transactions. can i buy my lunch with bitcoin?

>> i'm sorry, you used not anymore. we actually had an a.t.m. before but we don't have it anymore. i'm sorry. >> reporter: a bitcoin a.t.m., that is. nearby thelonioumonkfish does still take bitcoin, but because of transaction fees and the hassle, only if you spend $100 or more. so i'd have to order a lunch that was more than $100 to use bitcoin? >> right. to get the transaction go through. >> reporter: look, we even went to a bitcoin dealer, the l.a. chic boutique pawnshop in somerville. for cash, you can pick up designer bags by the dozen, a pair of shaquille o'neal's hard- to-fill shoes, even this poppin' fresh pendant whose provenance can be traced to boston mobster whitey bulger. but to do a bitcoin deal... >> you sign up an account and then we can meet over there at starbucks and we can transfer money at that time. >> reporter: proprietor dylan mcdermitt. well why can't we do it here in the store? >> ooh, regulation at this

point, we can only sell and charge a sll fee but buying? not at this point. >> reporter: but we can do it outside at the local bar or the local cafe here? >> yeah. we pay 90% as well. >> reporter: yes, only 90% of market value, plus a small aansaction fee. and yet, despi the hurdles to using it, bitcoin, and its underlying blockchain technology, are seen as fat city. consider the recent rash of conversion experiences. in december, long island iced tea re-named itself long blockchain and its stock price tripled. >> welcome to hoots! >> reporter: in january, a company with nine hooter franchises put its loyalty program, the hooters hoot club, on a blockchain, andts stock price jumped 50%. >> i'm no expert on bitcoin. >> reporter: richard thaler won this year's nobel prize in economics. >> but it's very hard to know

'sat its intrinsic value is and ery hard to know what it's ksgitimate use is. it certainly like a bubble to me. >> reporter: vikram mansharamani, who taught a course at yale on bubbles, agrees. rn it reminds me of the internet phenomenon, the in bubble, where people would add the dotcom and their stock price would go flying up exactly comparable in my eyes. >> but you know, bubbles sometimes keep going up. >> reporter: so is bitcoin a bubble that's already bursting, plunging by two-thirds in just a few months? or a great investment that's up more than 100-fold in the la five years? tonsharamani's book, "boombgy," looks for bubbles through several lenses. >> the firco lens is micrmics. normally when you have higher dices for a good you should see leand. when higher prices generate more demand we have a bubbly dynamic that results in higher prices generating more demand, rating higher prices etc >> reporter: in other words, instead of turng off buyers, the rising prices are attracting

them, triggering another lens: buying an investment on credit. >> are people borrowing money to invest in something because they are so sure it's going to continue rising? and in fact we've seen that recently. lens three, people want to believe. >> reporter: the psychology of y rational exuberance. >> tnt to believe in a new story, a new era, a new dynamic. this is a common phen. we saw this back in the 1920s with radios and cars. you saw it during the internet bubble where the internet was going to change everything and in fact you can see it today in this crypto domain where this is the new form of money. digital gold. >> reporter: mansharamani's last lens is a question: is the enthusiasm epidemic? >> think of a speculative mania as a fever spreading through a population. how many pple are left to infect? itll, if everyone is infected, the disease has rucourse, we're done! >> reporter: but you don't know that, right? >> no idea at all w much of the price is attributable to

actual fundamental interest in a non-printable currency versus "this is a party, it's rockin', over? or about to get its second i want to join it." >> reporter: so, is the party over? or about to get its second wind? as with any investment, mansharamani doesn't know, and neither do you or, even as the well-seasoned econom correspondent for the pbs newshour, do i. this is paul solman reporting. >> yang: on the newshour online right now, the national memorial to peace and justice opens today in montgomery, alabama. it confronts this country's brutal history of racial terror. ouffrey brown recently visited and spoke wither bryan stevenson. g/nd his report on our web site, pbs.wshour. and that's the newshour for tonight. i'm john yang.
