g every block of new york city. babita: welcome to "world news america," coming to you this evening from london. saudi arabia's foreign minister says criticizing the leadership of the kingd is a redline. speaking to the bbc, he said that includes the calls forpl ing crown prince mohammed bin salman, who he maintains is not involved in the death ofam journalist khashoggi. his comments are a day after president trump issued a statement saying we will never know if the crown prince was involved in the murder. i'm chief international correspondent -- our chief international correspondent lyse doucet sports unshakable bond, bu the u.s. congress now has the rights in its -- prince in its sights.

they want to know what role he played in the murder of jamal khashoggi. but in riyadh, the top diplomat hit back. >> the crown prince was not involved in this. we have made that very clear. shwe will puhe individuals who are responsible for this and we will make sure it doesn't happen again. se: so is this a red line, whatever the evidence is -- >> show us the evidence. show us the evidence. ifurkey has the evidence, please provide it. all we hear is. lea show us the evidence. and then we talk. it is a redline when you have individuals calling for replacement of our leaders. that is ridiculous and unacceptable in saudi arabia. lyse: there is another crisis, two, yemen, said to be on the brink of the worst famine in living memory. saudi arabia is under mounting pressure to end the bombing and block is causing such suffering.

>> we are doing everything possible to minimize the suffering of the yemeni people. when we have a militia that is radical, allied with hezbollah and iran, tt launched more an 200 ballistic missiles in our towns are we supposed to sit sorry, we are oh, not going to do anything? lyse: if i understand you dicorrectly, s arabia and its coalition are not ready to do anything to bring an end to their involvement in this war? mr. al-jubeir: we have said we support a political effort to solution to the yemeni crisis. this week the saudi monarch set out his agenda for the year. his son the crown prince in the front row, a sign to saudi's and the world that the kingdom sets its own course. lyse doucet, bbc news, riyadh. babita: for more on reactions to

th president's recent m comment colleague jane o'brien spoke to "washington post" correspondent mary jordan a short while ago. jane: you heard him say that the conference had nothing to do with ts, and donald trump saying maybe he was, maybe he wasn't. what message does that send? mary: it tells tyrants around the world that if enough money is involved, it is ok. you can break international norms, you can kill people. e but human rights hprice. e shocked atle the president's statement here. jane: but many other presidents have had to deal and continue to deal with countries and rulers who have done terrible things. what makes donald trumd's stance erent? ma: i think that it is how he dealt with it. s, there is bad actors a people you havto deal with for strategic reasons.

but there was even a moment, there was an even a big push back. he was siding with the saudis against u.s. intelligence. we know how saudi arabia workrs of cthis didn't go down without the prince knowing. our own intelligence services saying that. when donald trump didn' -- immediately start talking about money, people read it not america first, but money first. iop think a lot of in the senate on the republican side, the president's own party, are pushing back big-time over this. jane: but isn't he also saying what i suspect many americans might be thinking, that this is not worth losing all that money, this is worth jeopardizing a relationship with a serious ally? mary: but there is a big difference between jeopardizipg a relationnd saying we don't tolerate this. let's have a moment.sa let'that america stands for something. you cannot take someone who is living in the united states,

lure then to turkey, kill then, dismember them, and you know what, jobs, that trumps that. ia is not saying he will never deal with saudi arbut a people shocked there wasn't even kind of "hey, we are going to have some kind of punishment."na now the and congress is taking that because they are shocked. they are also saying of course we have to deal with people we don't agree with, but there has to be some punishment for this amazingly heinous, horrible murder. jane: is that going to be enough? if congress does trigger action or new sanctions, is that going to be enough gtren what donald p has said? mary: it will be very interesting because donald trump reacts to public opinion. this case, because it waone man who was getting a paper to

get married, and there is video of it, people -- they understand ve want jobs, but we want to feel good that we ome kind of moral standing. it will be very interesting if trum changess we head towards the election if he sees we think we are better than this. jane: mary jordan, thank you for joining us. babita: in other news, british prime minister theresa may says there are issues still to be resolved as she tries to finalize today she met with the president ean commission, jean-claude juncker, in brussels, and says she will return forore talks on saturday. the pentagon said it cost $72 million to deploy u.s. forces to the border with mexico in recent s to prevent illegal immigrants crossing. almost 6000 troops were sent to the border befe midterm elections after president trump warned of what he called an invasion of the country by a caravan of central amemican ants.

south korea's kim jong yang has been elected the new president of interpol. concerns were expressed about another candidate, fearing that he was too close to the kremlin. an american tourist has been killed by members of an endangered tribe in a remote island of india.wa the 27-year-ola christian missionary who was killed with bows and arrows and his body was left on the beach. the tribe lives in isolation from the rest of the world, and it is illegal to try to contact them. it has been three months sincene america lostf its great statesmen, senator john mccain. the nation watcheds the family urned and vowed to carry on his legacy. his wife, cindy, is doing just that by becoming chair of the mccain institute, which focuses

on international security. my colleague yalda hakim sat down with mrs. mccain to talk about her husband and the enduring lessons he has passed on. yalda: when the news came of his passing, there was this extraordinary bipartisan outpouring. why do you think the nation reacted in that way? cindy: john was truly the conscience o many ways the conscience of the country. people recognized him for his ability to work across the aisle, and his belief in working across the aisle. also, his willingness to debate but not demean as a result of difference i believe we have lost those ideals forever right now. if that makes sense. i think he represented so much to the country, and i'm hoping that we swing back and begin to realize the importance of doing

what john did. yalda: many people saysyalda: ms not just like a president had died, it was like a great president had died, and it stopped the nation at that moment. and yet the president wasn't there. ndy: well, you have to remember, even though it was a very public funeral, we are still a family. for all of us, and for the sake of my own children, i didn't want any disruption. this is about john, not about anything else at all in our country. it was iortant to me that we kept it respectful and calm and not politicize it. sounds funny coming from a political family in a political cotry. but it was important that we oopt it with dignity. i did not want thea. yalda: many speakers at his memorial spoke about unity. there was one of the biggest things that came out of the memorial but just soon after, we had theo supreme cour and the

whole kavanaugh fiasco. the enronment has become so incredibly toxic. elcindy: it is, unfortun once again we go back to i hate you because you are a different party. that is not hoit is, it is not how it should be. this 24-hour news cycle and the access to twitter and all these things have not helped this at all. i am hoping this election has proved that people areus little bit ated with what is going on, and hopefully it will change. john would have been so disappointed in this election just because of the nastiness and the discourse my state and across the country. yalda: there are a lot of pele who say that today's republican party has abandoned the things that john mccain or ronald reagan stood for.

where do you think the future of the republican party stands? cindy: i believe we will once again be a strong and moderate party. we are the party of abraham lincoln. i cannot believe that thisarty is just going to go away. it won't. but we have to learn from our mistakes. lick ourst wounds ant again. yalda: does the president have your support in the 2020 election? 't even know if he is going to run, and he is not sure. yalda: do you think he might not? cindy: i don't know. i'm like y, i have no inside track on this. i just hear what i hear.lo , i think we all need to support the white house in anything because it is our white house. we can be free to disagree and we can be free to voice our disagreements also. as far as supporting a candidate, i'm going to s of elective politics for a while. b i'n doing that for 38 years with my husband.

i just want to make sure that my kids are safe and my state is solid. yalda: but basedn his performance so far, if there was an election today, would he have your vote?' cindy: i 't answer that right now. i really cannot. at this point i would like to see some softening of the rhetoric. i really would. it is hurtful. yalda: were you hurt when the preswaent said he wasn't hero? cindy: yeah, i was. i thought it was inappropriate and wrong, i really did. it hurt the family, too. and it hurt the other men whose ed with john. it wasn't just abon, it was all the other people. i think that was a wrong thing to say. i don't know if i will ever get over it, i'll be honest.i bu the wife, that's my prerogative. i don't have to.

yalda: your daughter meghan t out at the president. she was tough. meghan: the america of john mccain has no need to be made great again because america was alwaysreat.a: yao you think that she is carrying her father's straight talking manner? [laughter] cindy: i think so. i did not know the text of the eech. t.knew she was giving one, but i hadn't read i was so preoccupied with so much. i thought she did an amazish job ngspoke her mind. i would expect notess from her or any other mccain, either. it is interestinto watch your kids grow, especially meghan, because sheit defy is john mccain in a dress and we have been saying that all along, since she was a kid. she has his temperament and his style.

yalda: johmccain changed the world. how did he change your world? cindy: oh my gosh. i have the good fortune of knowingis and marrying incredible man and having ah family wm. i had a front row seat to history in every way. i never expected that kind of life. i never expected anything close to it. it was truly amazing. it is something that i think we wwill miss him for the obvious reasons, but he was the life of the party. he was the one that when he walks through the door, he knew youwould be a good night know what i mean? i am going to miss that about him. the yeah, he was something else. bata: cindy mccain there. you are watching "bbc world newe still to come on tonight's

program, the exodus is on for , but once you get there, what will keep a family from fighting? we broughtn an expert to tell us more. a british phd student accused of spying for the u.k.er gent has been sentenced by a court in the united arab emirates to life priso this report from five. reporter: matthew hedgespp in r times with his wife. the acad arab emirates to report on the country's foreign policy. as he was about to return to the h u.k., he was detained, ws family saying that he was hcod in solitarinement, forced to signar confession in ic, and said a cocktail of drugs. he was sentenced to life in prison. his wife issued a statement -- " i am in complete shock and don't know what to do.

matthew h innocent. th been the worst six months of my life, let alone for ditt, who was shaking when he heard the." the u.k. and uae has have historically enjoyed warm ties, but it appeared today's verdict came as a surprise to the itish government. >> we have given repeated assurances about matthew. there are going to be serious diplomatic consequences because this is totally unacceptable. reporter: matthew hedges' colleagues say there is no legitimate basis for his arrest. >> the authorities have provided very little about this was a matthew was brought to their attention by a citizen of the uae who is concerned about the questions he was asking. we don't know who that person was. as far as we are aware, that person remains entirely anonymous. reporter:ge matthew ' family maintained hisug innocence thut, saying his mental and physical health have

worsened while being detained. the court says he will have 30 days to appealor butow, i nightmare for one family is becoming another diplomatic crisis for britain. babita: welcome. there is a lot of preparation that goes into a holiday feast, but nothing can ruin the meal faster than a fight over politics. so how do you avoid he things turning into a food fight? my colleague jane o'brien spok to a social scientist atit columbia univebefore they headed out for thanks giving. jane: talking politics at the dinner table has always been pretty contentious. why is it so bad now >> we are living, as your viewers, i am sure, noknow, in

trrdinary times. there is politics of more contentiousness,eanness. some of that comes from politics, media, andt is an -- and some of it comes from tribal politics that existed in the t u.s. and u.k. and around the world. and that kind of low tolerance for frustration right now. i think people wonder when people get into conversations that have political tensions or personal animosities, i think things are hotter. things escalate more quickly these days. jane: you have a wonderfully "difficult conversations lab" at columbia. what have you found? pu one of the main things we found is that thhline is complexity. when people are able to stay in an emotional place where they ioel perhaps some frustratn, perhaps some ang about the

issues, that they can move back and forth in feeling a little bit of positivity, a little bit of negativity, and there is movement emotionally, and there is movement cognitively, so people tnk about the issues, whatever they are talking about, whether it is brexit, the trump administration, or health care in this country, if they can hold onto a more complex and nuanced understanding of these issues, these issues are immensely complex -- urne: that sounds like a lot to think about overy. what practicaldve you have for those of us who are goingkeo he plunge and talk about politics? >> i guess it would be not to attempt to resolve tribal issues. i think that being mindful of the fact that these are extraordinary times, thinking a little bitbout what you want to do at thanksgiving, what kinds of conversations want to have. if y are moving into persuad your uncle who is stuck in a different point of view than yoh

are, i is really what you want to do, maybe thanksgiving is not the right time to do that, and maybe you should think about the conditions under which you have that kind of conversation with someone else. y have a relationship with them that would tolerate that? or have you in the past triggered, escalated conflicts, gotten into more difficult conflicts with that pemeon? when it to these deeper issues around values, they are harder to navigate, particularly in the short term. bita: probably not -- jane: probably not over the brussels sprouts. whether you are talking about politics, or not, thank you. happy thanksgiving. >> my pleasure, thank you. babita: love that idea of a difficult conversations laboratory. this story gives new meaning to ong walk. over a period of 30 years, he has visited every block of every street in five boroughs of new york.

this week a movintopens docume his urban trek. tom brook has the story. tom: chinatown in new york on a typical day. they go about their business. for matt, it means continuing his marathon citywalk. >> i am walking every block of i every streetthe five boroughs. i'm al walking through parts, -- parks, cemeteries, beaches, covering all the outdoor public g area, and just seeat is there. tom: while he has been on his walk, he has lived on a shoestring, staying in different apartmts in exchange for activities such as cat sting, and raising money for donations to his website.e strangely,said, he doesn't know why he spent almost seven years walking arcond new york ring a distance of 9000 miles. >> i think it occurred to me early on that a lot of times we feel like we have to have a way to sum up what we are doing and explain why itportant, this societal pressure to

be ablee to packat up and put a nice bow on it and tell people about it. also i don't re know why. tom: in new york, he has quite a few followers who monitor his progress. now a wider audience is being introduced to his urban walking adventuresy of a new documentary chronicling his exploits which opens in cinemas th week. it is a distillation of 500 hours of video shot by the director. >> so it is like a mission? >> y, it is like a mission. >> aren't you tired? >> a little tired. >> the movie is abou discovering the amazing that is in fro of your eyes. you can just walk the streets and discover everything that the city has to offer. i hope the film conveys that it is a sort of different look at the world, and it is sort of asking people to slow down a little bit, to notice ings around them.

>> butterfly and orange flower -- i saw that in marine park a couple years ago. tom: jesse eisenberg, the hollywood actor who is executive producer of the filmbelieves he has taken on the mission simply because it was there to be done. >> there is a quote by edmund hillary, whitey climbed -- why he climbed mount everest, because it is there. there is something about accomplishing this thing for the sake of itself rather than somed kif capitalization of it. tom: matt has 500 mileleft to go. he knows where the walk will finish, the street where he started, where there is a new york pza parlor, nail salon, and a bagel shop. to mark the completiwo of his , he intends to sample the offerings of all three establishments. tom brook, bbc news, new york. babita: perfect city to do it.
