Jane it was another day which had those on wall street searching for the painkillers. The Dow Jones Industrial has taken another dive, losing moreh 1000 points. It comes after a wild week, and analysts are again pointing a to concerbout the bond market and inflation. For the rest of us can it is ging new meaning to the wo volatility. The bs correspondent yogi lamaye j ago from new york. E how worried are traders . Yota i spoke to one this week, and he told me on tuesday to buckle up and be prepared for the ride. I think ey were expecting the volatility to last at least a week. I dont think they will be surprised. Of course there are worries and concerns, just given how much it is falling. More than a thousa points down again today, 4 down today. The other big indices as well, beound 4 down, anyway. I think they have anticipating this kind of volatility, but the severity of it has been taking them by surprise. But it stems really back to the same thing we saw on monday, which is fears that interestis rates willrapidly. Gger seems to have been market and the bond market. Throughout been this push and pull between the stock market and the bond market. The yield from the bond market tolyhed a fouryear high bri today. Bonds, particularly those issued by the u. S. Government, are consider a safer investment than equities anstock markets. That is why you are seeing is why you are seeing this push and pull. That seems to have been the trigger today. Jane does it signal trouble in the broader economy that donald trump has put so much stake in . Yogita not really. In a sense equity market not a good barometer of how strong or not the economy is. All of this was triggered last friday by a report that was pretty good for the economy. S wed that jobs are growing faster than wages, althoughon stil moderately rising, but faster than what was expected by people on wall street. What the white house as well as the president have been pointing out is not untru fundamentally, nothing has changed for the u. S. Economy. I think the surprise on monday was if you were taking credit for the stocmarket rising to rerd highs, then you should be coming out and saying something when it slide. Going down the of course, we did see that tweet from the president yesterday where he said that in the old days when it was good economic news, stock markets used to rise. And now they fall and it is bad. Jane yogita lamaye, thanks very much for joining us. White house staff secretary rob porter announced histi resig over reports that he physically abused his two former wives. In a statement, chief ly staff john kaid he was shocked by the allegations, which some officials said had been known for some time. For re on the administrations response, spoke a brief time ago with jeff mason of reuters. Just how troubling is this for the white house . Jeff it is troubling for the white house because this is somebody who was very important in the inner circle. He was essentially deputy chief of staff kelly. F of staff john a righthand man to president trump, there a the time, and his role as staff secretary was to be gatekeeper of paper for t to thegs that make president s desk. So that is a very key role, and he was an important figure, and a lot of people in the white house were shaken by thesere rts, and that is one reason why it sounds like they are saying now that they didnt perhaps react quite as quickly to the allegations from his exwives. Jane thats right, they seemed to be defending him right until the 11th hour, particularly chief of staff john kelly. What changed . Jeff what changed is the photograph came out one of his former wives showed a picte of her having a black eye, saying he had hit her. The photographic evidence, rightly orrongly, was enough to change the tune or the message that came specifically from john kelly, who released a statement pretty late last night saying that he had seen the latest information about rob porter. At todays white house briefing, they said his resignation had been accepted, and after havingi satially that he would stick around for a transition, th jane you were at the press briefing where this was discussed. Was it clear to you at what point officials were aware of the broad allegations . Jeff well, it sounds like certainly this week, tuesday or so, is when they started getting information about it, and yecerday when the photograp evidence came out but there has been Background Investigation going into him for some time,reecause that is ired to get security clearance. That happens for anyone who is working at the white house and requires a security clearance like that. He hadnt gotten his final ncclearae because that Background Investigation was still ongoing. Jane does that raise issues of Security Breaches . Because, as you say, he was handling documents and presumably some of them were classified that he was heading handing to the president. Jeff im not sure it raises questions about breaches. It certainly does put more of a spotlight on how things work at onthe white house when yot have the final clearance, because it sounds like he was working on a temporary clearance and had been for some time,as because heeen a member of the white house staff since the beginning. It will no doubt put a spotlight on how that process works, and even raj shah, the Deputy Press Secretary who briefed today, said, look, we dont normally talk about this issue, we dont talk aboutlearance, but we nt to provide context. That was unusual for them, and the reason ty had to do that and will continue to have to do that in the coming days is because of how rob porter has been operating uuntil now. Jane jeff mason, thanks for joining me. Jeff my pleasure. Jane syria has accused the u. S. Led collision of war crimes after a sees of air and artillery strikes killed 100 progovernment fighters. The american said that coalition advisers came in came under unprovoked assault and has the right to selfaifense. Moscowit would raise the matter at the un security council. British mps gathered in washington today to grill tech giants about interference in the brexit campaign. Representives from youtube, twitter, and facebook, pushed against the idea that their platforms were widely used by russia tsway results. Aleem maqbool was at todays there and he joined us a short time ago. Fake news is a broad umbrella. What was the actual foees . It is unhelpful, considering what they were looking at. They were looking at the dissemination of any information that was either incorrect or harmful, talking about thingske oogles autofill function on the searches from where it fills in the rest of the search. They questioned why that was directing people to hate websites. They talked about youtubes up next feature, where the recommendation for the next video or keeps playing, and sometimes it displays farright videos. There were lots of things being looke at. Most of y was spent with Tech Companies saying, yes, we care, we are responsle, and the mps saying we dont believe you, what you are really about is all of us spending more time on your platforms so you can make more money. Jane here in the u. S. It is the emphasis on fake news disseminated by the russians to interfere in the 2016 election. Hows think it impacted brexit . Aleem this was a fake news inquiry. Th is what they are calling it. But a lot of the focus during the day was about the potential cause of some of theat they see as the disinformation spread by russia through the social platforms. They think it happened and they want to know how it happened, how much it happened, and all of e these Tech Companies say have evidence that russia interfered with our platforms whent came to the u. S. Elections. We just dont have the kind of evidence when it comes to brexit. But they promise to look into it more. Again, the mps were not convinced theyould do that. Jane what can they do . Well, that is the i spoke t point. Mps afterwards and it said it is all very well that you are unhappy with them, even as they are telling you that as far as they know russia has not interfered, buisuntil there omething enshrined in law which says these platforms are legally responsible for what they show, the information theyt put out thern there isnt much that these mps can do. But they say they will go back and make recommendations that they do become law. Jane aleem maqbool, thank you for joining me. One man helped create the abomb and another survived its demonstration. Destination. More than 70 years later, their grandsons are cocreators on an art piece which commemorates the tragedy of hiroshima. R imagetallation af requiem includes 108 humanscale photographs on those who lost their lives. The exhibit comes at a time of heightened narlear tensions nd the globe. The name of the work is after image requiem. He we hope initle to evoke a sense that this is an ent which happened in the past, but the piece is very much about our current situation. We are right now in the midst of a crisis, a nuclear crisis, the likes ofhich, and the severity of which, we have not experienced in my lifetime. As an artist who lives in america but has japanese heritage, i make artwork about abomb, but the one thing im afraid is that people think or only make arabout history. The nuclear issue, the tension between all the countries, ared real, is happening right now. When school began at the Maryland Institute college of art, we didnt get a chance to b talk about okgrounds for a while. It was pretty busy. So when we finally spoke a week and half or two weeks into scho starting we were discussing about art. And i mentioned about my grandfather. He said his grandfather was atiroshima, i asked, was he there when the bomb was dropped . He said yes. Su hived, but he died from cancer. The whole room went quiet. Look, i have got to tell you something. My grandfather was an engineer who worked on the manhattanec pr so i use color darkroom paper. Lt it is a dying e. Not many people use it anymore. But i use that and use sunlight to create artwork. There is something beyond my control, just like abomb. So we went out to new mexico, where i did field recordings outside s alamos, and down near the trinity test site, where they tested the first apon. You hear a lot of the sounds of the plants rustling in the breeze, the insects, and then is a variety of techniques and audio engineer tricks to create sounds that are meant to evoke the processes that led todi builng the bomb. I was actually quite t surprised wh baltimore ial people were excited to do this show. After developing a friendship with them, they ld me this could never happened 10 years ago. The fact we can actually do this show in this space is a significant portit of change, changing the people, changing the generation, changing the peoples mindset. It portrays something good is happening in the world. Jane the artwork looks stunning, but does the building, and it is in baltimore not too far for me to visit.
