and a warm welcome. white house insiders are telling congress disturbing new details about president trump's now infamous phone call with ukraine's leader last july. they include how the call transcript ended up on a highly classified server and who blocked $400 million in military aid to ukraine. now, on saturday, a senior white house budget official said he was confused by the aid had been put on hold. a trump political appointee apparently took control of the ukraine account outside the normal budget process and then signed documents freezing the funds. also on saturday, transcripts from two earlier depositions were made public. cnn's lauren fox with those details. >> reporter: on saturday, we got new details about tim morrison,

a former nsc official, who testified to congressional investigators last month that he came to understand that eu ambassador gordon sondland was getting direction from donald trump when he was pushing the ukrainians to announce investigations into the president's political rivals. morrison testified behind closed doors i believed sondland and president trump had spoken five times between july 25 the date of the phone call between president zelensky and president trump, and september 11th when $400 million in usaid to ukraine was finally released. he said in one of those conversations he spoke with sondland after sondland had gotten off the phone with president trump. "he told me he had just gone off the phone with the president. he told me as it relates to ambassador taylor's statement, there was no quid pro quo, but president zelensky must announce the opening of the investigations and he should want to do it. tim morris also providing details about the 25th phone

call, especially the fact that that was put in a secure server. there are questions of course why it was put in that server. morrison said he came to understand from the top nsc lawyer that it had been put there by mistake. here's what he told investigators. john eisenberg related that he did not ask for it to be put in there but the executive secretariat staff misunderstood his recommendation for how to restrict access. that's a reminder that next week both individuals will testify publicly in front of the congressional investigators and the american public. for cnn on capitol hill, lauren fox. and in the u.s. state of louisiana, democrats are celebrating a significant win and setback for president trump. the incumbent democrator governor john bel edwards narrowly beat his challenger who was heavily backed by the president.

louisiana was a state that in 2016 trump won by 20 percentage points. after weeks of more or less static standings among the top-tier candidates, pete buttigieg is having a breakout moment in iowa. jeff zeleny with the latest polling. >> reporter: there is a new democratic front-runner in the 2020 race in iowa and his name is pete buttigieg. for the first time, the south bend, indiana mayor claims to 25% in a new cnn/des moines register iowa poll. warren, biden and sanders are locked in a three-way race for second place. amy klobuchar, the only other candidate to breal out of the lower tier, with 6%. buttigieg has risen 16 points.

warren and biden have slipped. the race remains fluid with 30% saying they have made up their minds. still 62% of likely iowa caucusgoers could still choose another candidate. that gives a sense of hope to a dozens other democrats still in the race here. this is why second choice so important. elizabeth warren is the second choice of 20% of likely caucusgoers, followed by buttigieg at 14%, which sanders and biden each at 13%. electability is a critical question for democrats. that remains the core bit of biden strength of the four top candidates tested. a majority, 52%, say biden could beat trump. the rest do not reach the majority point. this is where the race is standing right now. there is a sense of pragmatism hanging over iowa voters as well. 63% prefer a candidate with a strong chance to beat trump, compared to 32% of someone who shares all their views.

so that's where this race is now some 80 days before the vote anything 2020 begins. now the question for pete buttigieg is how does he handle the pressure of being a front-runner. jeff zeleny, cnn, washington. and let's bring in thomas gift from the university college, london. a pleasure to have you, sir. talk to us about this testimony on saturday. you had a couple of people, one called the trump/zelensky call unusual and concerning. and a lot of concerns about the role and truthfulness of gordon sondland. what do you make of the testimony and its potential impact? >> i think the biggest takeaway is gordon sondland has a lot of explaining to do and seems to be at the center of a lot of irregular discussions. i think viewing in in the context of what happened last week, it's very much the case that there is overwhelming evidence that a quid pro quo did

exist. it wasn't just the result of one phone call july 25th, but this was a concerted effort going to the highest levels, including the president. the question is for republicans, how do you respond to this? they have been a little bit uncertain on what their line of justification is. even if this happened, even if it was problematic, it just doesn't rise to the level of an impeachable offense. at least that is the case they are going to try to make to the american people. >> do you think there is a cumulative effect here? every day it is sort of another one adding to the pile that sort of shows that things weren't particularly, i don't know. donald trump openly said he hardly knew this guy, gordonen sondla sondland, the man who can call the president on a cell phone at a ukrainian restaurant.

he said it was his understanding sondland spoke to trump multiple times and said he believed and at least related to me that the president was giving him instruction. that is hardly someone you don't know. >> yeah. he certainly doesn't seem like a peripheral figure. i think it is important for donald trump to make the case that he only had limited contact with him. i think ultimately what democrats and republicans will be looking at here are the poll numbers. the standard narrative going into the impeachment inquiry is democrats were going to impeach in the house. and then the republicans would block in the senate. if you look at approval ratings for donald trump or approval for impeachment, there hasn't been a whole lot of movement since these actual public hearings began. so i do that that militates this argument that there is a lot of momentum for democrats going forward. we will see. there is still a time to go.

. >> well, there's eight more people testifying this week. who knows what we will end up with. it is something that the support for nixon's impeachment didn't move until towards the end as well. one of those people testifying this week, if he turns up, is gordon sondland. what sort of jeopardy might he be in in terms of truthfulness? he has offered up two versions under oath. the first one. then he amended that. who knows what we will see with version three. what sort of risks is he taking? >> well, or there political risks and legal risks. this is someone who has provided testimony and had to revise that testimony. so there is a big question mark i think in the minds of both democrats and republicans as to what gordon sondland is ultimately going to say. i'm sure the american public will be watching intently. so will donald trump. but i think we just don't know at this point is the bottom line.

. >> yeah. i was going to ask you, too, while we had you about the iowa poll and what you made of that with the results. pete buttigieg ahead. it is iowa and it is a mainly white state. he doesn't have a lot of minority support. what do you make of the momentum for him? . >> certainly the poll numbers are much stronger for pete buttigieg in iowa than they are nationally. so it's hard to assess the extent to which this really suggests that he has momentum across the spirit of the united states. but certainly these early primary states matter a lot. and it's great to get this early momentum. i think a lot of his support probably says more about some of the other contenders than it does about him. with biden's candidacy stuck in neutral, voters are looking for a moderate with a progressive streak. and i think buttigieg really fits that bill. one question for him is, is he

peaking too early? he has significant ground game in iowa, a lot of mobilization there. when you think about candidates that have done well in the past, including barack obama in 2008, they really hit their strike just a few weeks out. at this point we're self months out. the question for him is can he continue this momentum going forward? >> very good point. i want to ask you about the louisiana governor's race on saturday. had you have john bel edwards who beat out eddie rispone, a deeply red state. donald trump, he invested a lot in this race. he had two rallies in two weeks. he had three rallies in the last five weeks. my goodness, a whole bunch of tweets and retweets on this election. is that a reflection on his problems, or do you see it as more a local issues election? . >> well, i think it's a bit of

both. it is worth pointing out that edwards is certainly to the right of his party overall, especially on issues like abortion and gun control. i think he did do a really good job with resonating with louisiana voters in terms of kitchen table issues like access to early childhood education, expansions of medicaid, workforce training and increase in the minimum wage. in a lot of ways he just did a better job than the republican in terms of appealing to louisiana governors. it raises the question how much impact donald trump really has in his ability to dictate outcomes from washington. he really put a lot of his political capital into this race just like he did in kentucky. does that suggest something for 2020? does this suggest that some of his support might be soft and will some of the states become swing states that haven't

traditionally been so? that is the question that remains. >> yeah. with the candidates going forward, some of them may not want him to come and support them. thomas gift, got to leave it there. appreciate it. thanks for your insights. >> thank you, michael. mr. trump went to the walter reed medical center in maryland to apparently begin procedures, including lab tests for his annual regular physical. previous exams had been announced ahead of time, though. that's what made everybody's ears brick up on this one. they say he is healthy and energetic. the u.s. and south korea just made a diplomatic gesture towards pyongyang. they are postponing joint military drills later this month. it is called an act of goodwill during a joint press conference

in bangkok. mark esper was asked if this was a concession to north korean leader kim jong-un. >> i don't see this as concession. i see this as a good-faith effort of the united states and republic of korea to enable peace, to shape the terrain, if you will, to facilitate a political agreement, a deal, if you will, that leads to the denuclearization of the korean peninsula. and that's what we do. as i said earlier, my job is to enable and empower. at this point it creates more space for our diplomats to strike an tkaeplt on the denuclearization of the peninsula. we'll take a break. when we come back, a new standoff erupts in hong kong. demonstrators taking on police

iran's supreme leader said he supports raising prices. >> in hong kong, a standoff between police and protesters getting even more violent. authorities say a police officer was shot with an arrow during a dispersal operation at polytechnic university. he was wounded in the calf and taken to the hospital. authorities surrounded that university now trying to force out pro-democracy demonstrators who have really set up defenses there. they fired tear gas and water cannons who retaliated with petrol bombs and bricks. let's head out to anna coren for an update on the situation. petrol bombs and you have the gas mask on?

>> reporter: i have the gas mask on, michael, because tear gas has been fired over the last hour since we last week. they are expecting police to charge very, very soon. we are standing outside polytech university. down here is where the two water cannons are. they have been throughout the day spraying water, charging, retreating. but they have kind of held their position. they're shining their really strong lasers on this direction of this overpass. on the other side, are dozens of riot police vehicles with riot police standing outside and vehicles firing tear gas. there is a twhaul protesters have built on top of this overpass, which is over the crest harbor tunnel that leads

to hong kong island. protesters have built a wall. they have been throwing petrol bombs at police in the last hour. it looks like they are gearing up, the police are gearing up, to try and clear this area. behind me, michael, we are seeing morais on the police vehicles. so the protesters are saying try to protect this area as much as you can and then protect the university. they believe here in this university they can get to the second story. there is a balance con there. they can throw petrol bombs. they have catapults up there where they have been throwing stones from bricks. we haven't seen them throw petrol bombs. but police say they have been throwing them from the catapult as well. bow and arrows as there are several archers up there.

they say they are going to dig in. this is the last step. all the other universities across hong kong have fallen. but the protesters will dig in and try to protect the university against their police. as the protesters said time and time again throughout the day, we are at war. as far as the police are concerned, everyone here are rioters. perhaps only a thousand or a few more protesters here that have come from other universities where they have been taking action throughout the week. they have now all intended here at polytech university. as i say, this is the final step. >> keep an eye to or us, anna coren. thank you. anna coren in hong kong. as the protests rage in on hong kong, anger against the government mounting.

there is one service department growing in popularity and that is the fire brigade. as police often are criticized for their handling of unrest, firefighters get an applause. a small but growing number of firefighters admit they support the protest movement. >> reporter: a hong kong firefighter points to his swollen face. riot police accidentally hit his engine with tear gas. tempers flared on both sides. police pushed the firefighter into a corner and for chasing and spraying a journalist. police and fire rushed to issue a joint statement within hours, calling it a misunderstanding. these men say it's more than that. >> reporter: two firefighters

and one paramedic will only talk if we hide their identities. >> have you ever participated in the protest covering your own faces. >> yes. >> do you think you would be fired if they ever found out? >> of course we would get fired. >> they say many colleagues have joined the protest, ignoring warnings like this. >> translator: you can't stand against the government showing a negative image to the public. >> reporter: videos like these show what some consider government-sanctioned police brutality. they generally lack context about what happened before. . >> police is using excessive violence when they are arresting those young people >> can you describe what kind of excess of violence you have witnessed. >> when someone is under arrest and they didn't fight back, they

are just lying on the ground, and police were still beating them. and now it's like a common practice. >> every week? >> like every protest. >> this woman peppered sprayed and pushed to the ground. this office workers head injury said to be from a tear gas canister. protesters shot in the torso with live ammunition, all in the span of two days. amnesty international accuses hong kong police of being out of control. >> i cannot believe we are out of control in our force but we are under pressure. >> hong kong police sent us this video, frontline protesters beating an off-duty cop. the firefighters watching say they tried to help but were

outnumbered. bricks and petrol devices are the favorite among protest. metal poles and flaming arrows. this government supporter was doused with flammable liquid and doused on fire. >> these rioters acts have gone overboard with their demands and these acts are the enemies of the people. >> would you dispute the fact that the protesters are also putting lives in danger through their behavior? . >> yes. you are right. some small groups of protesters are putting things in danger. that is undeniable. but for me i understand what they are doing. . >> so if you had to pick a side, would you side with the protesters over police as a firefighter? >> yeah. i would be on the side of the protest. >> why? . >> they are desperate. >> they all say the biggest

challenge facing hong kong right now is not violence, it's lack of trust. >> no one is trusting each other. that is why we are hiding our face. people don't trust the deposit. we don't trust the police. and there's no way back. . >> and no way forward from a 70-year-old man hit with a brick and the 22-year-old student who fell from a parking garage, two protest-related deaths in just one week. bill ripley, cnn, hong kong. well, the impeachment storm in the united states revolves around ukraine. ahead, why the former soviet republic is in the middle of ajeeeopolitical tug-of-war. also, in an apparent effort of damage control, prince andrew is speaking out about his friendship with the late convicted sex offender jeffrey epste epstein. and because it's a ninja foodi, it can do even more,

russia, it is sort of leaning west, not fully embraced by the west. >> until the breakup of the soviet union, it was the ukrainian soviet socialist republic, firmly within moscow's sphere of influence. that came to an end in 1991 and ukraine face aid crossroads. >> there was so much scope for how to reimagine europe. and i think ukraine was especially problematic for two reasons. one is that it wasn't just on the periphery. it was core to the soviet union's understanding of who it was. secondly, it had all of these weapons. >> in 2000, nukes in ukraine. an unexpected crisis solved with a 1994 agreement in which kiev gave up the russians and russia, the u.s., and the uk said it would respect its sovereignty and existing borders. but in 2014, ukraine found

itself once again at the center of tensions between russia and the west. in february, mass protests forced the pro-moscow president into exile. a month later, are issue that sent special operations troop into crimea and annexed it. to this day, ukraine is still fighting to reclaim its lost land. >> the ability of ukraine to root out corruption, to professionalize its military, to really maintain that independence is really completely conditioned the ongoing assistance from the united states. so it gives the united states and the president in this instance tremendous leverage. . >> this is a country that is effectively a buffer state, isn't it? >> yes. at the moment what we have really is the need to preserve what has become a buffer state but also not to deny the people in ukraine who would like to see

more integration with the west certainly economically and possibly politically. . >> ukraine may be thousands of miles from the united states, but the country's precarious past and uncertain future means whatever happens in kiev has become key on capitol hill. nina dos santos, cnn. prince andrew speaking publicly for the first time about his relationship with the late convicted sex offender jeffrey epstein. the british royal said he never saw anything suspicious while he stayed at epstein's new york home. the duke of york denying allegations from one of epstein's accusers who said she was forced to have sex with the duke. there is actually a photograph of the two of them together. the duke claims he has no recollection of the photo being taken or ever having met the woman. joining us now from london is more. bring us up to date on the latest revelations.

>> reporter: michael, this was an astonishing interview not just for the content but for the fact that it even took place. it is so unusual for a senior member of the royal family to sit down for an extended interview not connected to their charity work. it also took place in buckingham palace. it was done with the queen's approval. there were several interesting points in addition to him denying any of the allegations brought forward by the photo. he said he has no recollection of ever meeting her and he has alibis for when he said she met and expert acted with him. what was probably even more astonishing was his justification for continuing seeing jeffrey epstein even after he had been convicted of sex crimes while he stayed at his new york mansion in 2010, why he thought that was a good idea. listen to what prince andrew told the bbc. >> you said you went to break up

the relationship. yet you stayed at that new york mansion several days. >> but i was doing a number of other things while i was there. >> but you were staying at the house of a convicted sex offender. >> it was a convenient place to stay. i've gone through this in my mind so many times. at the end of the day, with the benefit of all the hindsight that one could have, it was definitely the wrong thing to do. but at the time i felt it was the honorable and right thing to do. i admit fully that my judgment was probably colored by my tendency to be too honorable. but that's just the way it is. >> what's really interesting, michael, about the comments is earlier in the interview he claimed he was a very good friend with jeffrey epstein. yet there is some confusion if

he can't such good friends, why delve he had to stay at his house, especially as a member of the royal family, staying at the house of a convicted sex offender. that is what a lot are still questioning today. another thing is due fray said if he is willing to sit for an interview, why isn't he willing to speak under oath to investigators. he told the bbc he would do so only if legal advice told him to do so. details are now emerging about what could be the largest initial public offering in history. saudi aramco giving retail investors a chance to own a piece of the world's most profitable company.

it could raise $24 billion, just shy of the $25 billion raised by aliba alibaba, the world's biggest ever ipo. we go to london with more. what do you make of this price range? >> i was trying to think of the best analogy to use. it is like the goldilocks tale. not too hot, not too cold, just right when it comes to this ipo go tprauforward. the value of the company overall and potentially still being the number one ipo in the world, beating al backy in september 2014. i'll tell you why. 1.6 to 1.7 trillion dollars for matters of comparison, well above a company like apple, which is valued at $1.2 trillion. amazon, microsoft. five times the size of an oil comparison company like exxonmobil or chevron. in that price range that was

listed there, they could get to $25.4 billion, beating the e-commerce giant in china. this is important to the crown prince. back in 2016, it was 5eu% listing in new york, london or shanghai or tokyo. we know it is 1.5% only in riyadh. this is a very important milestone. they have been talking about it for three years. it is important to get it out the door by 2019. >> what about, john, the timing by the crown prince of the saudi government, is this a good time to go public as an oil and gas company, climate change? a lot of things play into it. >> yeah. europe making key points here. almost like swimming upstream. to give you the best qualification for this, the s&p 500 on wall street used to have about 10% of the listings of market cap by oil and gas companies. that is below 5% now partially

because of climate change. partially that institutional investors don't want to hold them in their portfolios. it is not an easy time to list. if you take aramco on profits alone, $111 billion. they're in a league of their own. the final point is there is concern about peak demand. we consume 100 million barrels of oil a day. could that come in 20 years? even so, aramco is efficient enough to beat the competitors. people don't want to hold oil and gags talks right now. . >> thanks for that. we'll take a short break. when we come back, venice on edge as another round of flooding is expected to sub merge the city. a live look at how the city is preparing bushfires in australia. we hear from homeowners who lost

owners, the 32 teams, roger goodell, all of them to stop running. stop running from the truth. stop running from the people. we are ready to play. we are ready to go anywhere. my agent jeff tphally is ready to talk to any team. interview any team at any time. i'm staying ready and i will continue to be ready. >> this is one wild day. this is supposed to be held at the atlanta falcons facility. it was going to be closed to the media. scouts, members of the falcons facility had already arrived. they were waiting for this to begin. 45 minutes before it was supposed to start, colin kaepernick's representatives decided to cancel it and move it 60 miles south of the atlanta falcons's practice facility. one of the reasons they canceled the nfl's workout because of the liability the way they requested him sign. it had employment language in

there that colin kaepernick's representatives were not happy with. i spoke with his agent jeff mally and asked what that was about. >> he works out yesterday at the university. they asked for an injury waiver as well. so the four receivers all signed it, no problem. we allowed them to sign it. we sent that form to the nfl league office, and they denied it. the one they sent over was five or six pages. his lawyers had problems with it. . >> what was the biggest problem with it? >> i'll let the lawyers talk about that. but there were -- they wanted him to waive his right to certain claims and issues. and, again, the purpose for a waiver like that is to protect them if they get hurt, if the receivers get hurt. that's not what that waiver was. >> nalley said he thinks it was just a p.r. stunt. the nfl did release a statement saying they were disappointed he

decided to move the workout. they sent him a standard waiver to sign, they said. i saw at least 20 scouts going there to watch kaepernick workout. when the workout got moved to this stadium, only eight scouts showed. will one of those eight teams end up signing kaepernick? we'll have to wait and see. one thing for sure, there is still plenty of mistrust between kaepernick and the nfl. andy scholes, cnn. who is the guy running for president who loves to say, come on, man, more than any other candidate. jeanne moos reports on the famous catch phrase and comeback line of vice president biden. >> reporter: it is the ultimate joe biden come on. >> come on. >> come on, man. >> come on, man. >> reporter: used to convey everything from sarcasm. >> my heart breaks. come on, man.
