About Donald Trumps efforts to go after his president ial opponent Hillary Clinton. The New York Times reports mr. Trump wanted the Justice Department to prosecute clinton. And former fbi director james comey. But the white House Counsel warned against it, telling the president it could lead to his impeachment. A source tells cnn mr. Trump has repeatedly asked for updates on investigations into clinton. U. S. President is under fire, even from members of his own party about his latest statement on the killing of saudi journalist Jamal Khashoggi. Cnns jim acosta reports. Reporter just moments before a ceremonial pardoning of the thanksgiving turkey at the white house i will be issuing both peas and carrots a president ial pardon. Reporter President Trump delivered a chilling message on the killing of saudi journalist Jamal Khashoggi. In a statement that begins with america first, the president seems to dismiss the cia assessment that found saudi arabias Crown Prince Mohammed Bin Salman ordered khashoggis killing, saying it could very well be the crown prince had knowledge of this tragic event. Maybe he did and maybe he didnt. Leaving for thanksgiving, the president defended his decision to side with the saudis. Are you letting the saudis get away with murder . Murdering a journalist . This is about america first. Theyre paying us 400 billion plus to purchase an invest in our country. Thats probably the biggest amount ever paid to the United States. Dont you belief the cia they didnt make a determination. Maybe he did. Maybe he didnt. They did not make that assessment. The cia has looked at it. Theyve studied it a lot. They have nothing definitive. Reporter in a statement the president also appeared to buy into a saudi sphere of khashoggi, saying that Jamal Khashoggi was an enemy of the state and a member of the muslim brotherhood. Khashoggis family has blasted those claims as ridiculous. Secretary of state mike pompeo backed up the president s statement. This is a long, historic commitment and one that is absolutely violate to Americas National security. Its a mean, nasty world out there. Reporter but not all republicans are on board. Im concerned about our standing in the world and what it says about the United States. Reporter president s willingness to believe saudi denials is consistent with his posture on other undemocratic countries like russia and its meddle manage the 2016 election. Maybe it was. It could be russia. But it could also be china. It could will lots of other people. It could also be somebody sitting on their bed that weighs 400ed pounds, okay . His explosive statement comes less than a day after his own daughter ivanka trump came under fire for using her emails to do government business. It certainly looks bad and im sure the media will have a field day with it today. For what she has done that. Should lock her up. Reporter hypothetical because its a reminder that her father savaged Hillary Clinton for her email use. If i win, i am going to instruct my attorney general to get a special prosecutor to look into your situation, because there has never been so many lie, so much deception. Reporter a source close to ivanka brushed off the story in statement saying this is a 14monthold story. There was nothing there then and there is nothing there now. The president insists his daughter did nothing wrong. They werent deleted like Hillary Clinton who deleted 33. She wasnt hiring. She wasnt doing anything to hide her emails there was no deletion. There was no nothing. What it is a false story. Reporter as a for ivanka trumps email use, a source close to the white house and the family says the president s daughter obviously knows better as she watched the 2016 Campaign Like the rest of us of as the source put it, quote, ivanka deserves to get hit over the issue. Jim acosta, cnn, the white house. Richard johnson is a lecturer in u. S. Politics and International Relations at Lancaster University here in the uk. And he joins me now to discuss this. Plenty going on in u. S. Politics, but guess thats just a wednesday. What do you make of the president s assessment that maybe it was, maybe it wasnt Mohammed Bin Salman who conducted this extrajudicial killing of Jamal Khashoggi . And also, how unusual it is for a president to be so explicit about this kind of tradeoff between the kind of countries america wants to associate with and then also the economic damage it might cause . Well, i think you hit the nail on the head there that donald trump is a transactional person. He is a transactional president. And so for him, hes not hes going to weigh up what we views as at the bigger and better part of the deal, which is arms from deals with saudi arabia. You know, president s in the past have not had a great record on this either. President obama one of the few vetoes that he exercised and was overruled by congress was legislation by congress to allow victims of 9 11 to engage in civil suits against the kingdom of saudi arabia. And president obama vetoed that, in part because of a concern of damage it would do to u. S. saudi relations. Now this is not on the same level as the president effectively ignoring the cia report about the allocation of blame, but it does show that the United States for a long time u. S. President s have prioritized the u. S. Saudi relationship over individuals who might have serious claims against the saudi government. And richard, moving on to another big story coming out of the white house and the Trump Administration, what do you understand about the prosecutions which President Trump was trying to pursue with his Justice Department around Hillary Clinton and james comey . Well, its very the thing thats most concerning is the way in which the president possibly attempting to use the Justice Department for his own personal ends. And since the watergate era, president s have had to be very careful at the extent to which they issue instructions to Justice Department officials. There was an interesting report which came out this week which reflected on Richard Nixons close relationship with henry petersen, who had been an assistant to the attorney general and n the Justice Department. It was one of the reasons, one of the articles of impeachment against Richard Nixon is that he had opened up these back channels with the Justice Department for his own protection and for his own information. And so President Trump has to be very cautious about the ways in which he might be directing Justice Department officials either to provide him with information or to just ongoing investigations which might implicate him personally. And richard, speaking of the behavior of the administration, Donald Trumps daughter ivanka reportedly using her personal email account. Explain to us why thats an issue for somebody in her position and what the democrats plan to do about it. Well, obviously the first charge that gets raised against the president is one of hypocrisy given that Hillary Clintons use of a private email server was one of the centerpiece of his campaign against her and the source of the lock her up rallying cry. He argues his daughter is in a different position because she hasnt deleted her mails and for whatever reason was simply unaware that this wasnt allowed which seems somewhat implausible given the content of the election campaign. Thing is a bigger issue about whether ivanka trump should be having this job in the first place. Congress in 1967 passed an antinepotism law which was sben intended to prevent family members from working in president ial administrations. You know, this law in the past the Justice Department has advised president s that they couldnt do so much as appoint members of their family. Jimmy carter was told he couldnt appoint his wife to be chairwoman of a commission on mental health. I know the Trump Administration said they got around this because she doesnt take a salary, but i think it violates the spirit of this law. And i think its pretty the fundamental point that she is even working for her father in the white house is, you know, a cause for concern in itself given the context of the 67 law. Richard johnson, thank you so much for bringing us your insights and getting up early for us. Thank you. Thank you. Now another selloff on wall street. Stocks in tokyo and seoul have been down most of the day. Chinese markets in hong kong and shanghai have been in and out of positive territory. The dow dropped more than 550 points tuesday, wiping out all of its gains for the year. Plunging oil prices pulled down Energy Stocks and analysts say investors are worried about Rising Interest Rates and the ongoing trade war between the u. S. And china. Cnns alison kosik has more on whats behind the stock slide. Reporter all the major indices have wiped out their gains for the year. Its a headline thats undercut Investor Confidence and set the negative tone in the market. Tech stocks dragged the market lower. Ironic since it was tech shares like facebook, apple and google that powered the market to record highs over the last few years. But now it look likes the darlings of yesterday have turned into the dogs of today. Facebook and apple shares getting crushed. Both stocks are down more than 20 from their recent highs. Investors cant seem to sell tech shares fast enough. Facebook is dealing with the fallout from how it handled foreign influence in the 2016 president ial election. And apple is facing slowing demand for its marquee products the iphone. Investors are also spooked because there is a possibility for a regulatory crackdown that could change the way certain Tech Companies do business and cost them more money. Also weighing on sentiment, trade tensions wrapping up. Over the weekend, there was a collapse of preliminary meetings between the u. S. And china two weeks before president xi and President Trump are expected to meet. But the thinking is the issue wont be resolved. And that thats as President Trump has threatened to impose a third round of tariffs on 267 billion worth of chinese goods. And some tariffs already in place are set to increase from 10 to 25 on january 1st. If those go into effect, that could eat into Company Profit and possibly rattle the markets even more. Back to you. Thanks to alison for her reporting. Vicky price is an economist at the center for economic and Business Research and author of the freakonomics. Beijing hasnt addressed its unfair trading practices. That s thats whats driving . I think to a point. We are seeing a slowdown in Global Growth, but absolutely at the center of what is going on right now affecting all markets. And of course china had been hoping, there had been a number of meeting and weve all been hoping that some of the issues will be resolved. But of course the mood from the white house is still pretty aggressive i would say in terms of everything President Trump has just been saying. We suggest in fact that we are going to see a further imposition of tariffs on chinese exports to the u. S. , and that is worrying everybody. Of course it worries the europeans. It worries of course other asian markets because up to a point the concern is quite a lot of what china exports to the u. S. Is going to be diverted somewhere else. And that will actually cause difficulties for other countries that are also exporting the same type of stuff and competing with china. Thats one of the elements out there. If the world really slows down, as a number of people are predicting, and if were about to enter another serious crash possibly, and again there is quite a lot of speculation of, that it isnt just asia we need to worry about, it is the developed world. Everyone in the west as well who have been relying up to a point on the u. S. Leading as what had been a very, very slow recovery from the financial crisis. And the fact that there is a Global Growth slowdown, is that one of the key factors contributing the fact that weve just seen all the gains from the statement in the u. S. Just be wiped out . One of the things that is happening is the old price that looked like it was going to strengthen is now of course falling again. Its still quite high compared to where it was a little while ago. But there it is. Signs of concern about whether there is a nervous supply, whether the World Economy slowdown is going to mean that we dont neath need as much oil as perhaps is being produced right now. Thats another cater that of. If you look at whats happened to the. S, of course, in the u. S. , oil stocks suffered. But were seeing a much wider decline, which is also affecting tech stocks in particular, poered about regulation perhaps coming. Everyone has been talking about first of all taxing some of the profit a lot more internationally that the Service Companies are making. And the second thing is whether there should be more regulating in terms of have they become too big . Will they be broken up . It makes people think back to the days of oil, the Oil Companies where in fact it was lot of intervention regulation and they split them up. It may happen, and i think there is an underlying worry that perhaps the best days in terms of. S are over. And weve seen in fact as we all mow the gains of the last year in the u. S. Wiped out. And you mentioned tech stocks which did pretty badly yesterday in europe. And in fact, the markets in europe closed sharply lower on tuesday overall. Whats driving that . There may be an overvaluation. Thats what people are worried about. A, they have become far too big and so theyre ripe for some change there. A lot more control of what they do. There are all sorts of suggestion, a digital tax as well for all the International Companies that are becoming very big. There is concerns about competition, how can we allow a lot of the fimpls to move into Amazon Retail and so on which is going to worry markets as well. And a number of concerns about whether theyre doing things properly. So are they really respecting the date the of people and are they allowing others to use data in a competitive way that others are asking for. So there i think quite a lot there. I think there is a general concern about whether the growth weve seen in the u. S. This year is going to continue next year. Forecast for a slowdown after the fiscal boost is gone and Monetary Policy is tightening, thats making life more difficult including in the emerging market because a lot of them have borrowed in u. S. Dollars, and that is a big, big, big issue. 10 europe itself has got problems with the italian budget and rethinking how europe is going to be shaped in the future without the uk. So there are loads of problems there too. And slowdown in europe too. Look at germany, which hardly grew. The figures suggest that 4 in last quarter in gdp because theyre not selling as many cars to places like china, and thats an issue. Vicky pryce, thank you so much for joining us.
