that's it for us. thanks for watching. i'll see you back here tonight at 10:00. our coverage continues now with rosemary church at the cnn center in atlanta. trouble in brazil. two u.s. swimmers pulled off a flight and ordered to stay in the country amid their robbery claims. out of control, a fast-moving wildfire threatens more than 30,000 homes near los angeles. authorities say they have never seen anything like it before. and heartbreak. the story behind this picture of a wounded boy in syria that's gone viral. hello and welcome to our viewers here in the united states and of course, all around the world. i'm rosemary church. this is "cnn newsroom." we have new developments in

a story that keeps taking more bizarre turns. a lawyer for two u.s. swimmers says they've been ordered to stay in brazil until they talk to police about their report of being robbed at gunpoint. brazilian authorities have released the men have pulling them off their u.s. bound flight. they claimed that people dressed as police officers robbed them sunday morning. one of the swimmers involved has a bit of a different story. our christina mcfarland has the latest on what is becoming a growing scandal. what more are we learning about this bizarre story of the u.s. swimmers, and what's the possible fallout from this? >> reporter: rosemary, it's a confusing picture here tonight. let's get you caught up on what we know of the situation here this evening. two of the swim emers were remod

from their flights this evening. the police visited the olympic village to talk to ryan lochte and feigen. lochte wasn't there. they had moved out of the village after their competition ended. his attorney said lochte is back in the united states, adding that the swimmer still stands by the information he provided to police just a few days ago. later on wednesday, lochte's original story seemed to have changed. he told nbc that they were never called over, but had stopped at a gas station when they were ambushed. have a listen to this. >> when he talked to me tonight, he said that's when the guy pointed the gun in my direction and cocked it. i said to him, you said before it was placed on your forehead and cocked. he said no, that's not exactly what happened. and i think he feels it was more of a traumatic mischaracterization. people listening at home might

feel that was embellishment at the time. >> reporter: now, this is video appearing to show the swimmers going back to the olympic village hours after the alleged robbery. the judge noted they didn't seem to be shaken and they were making jokes. but at that is maybe open to interpretation. the men are also still in possession of high-value belongings you would expect to be stolen during a robbery. you have felt this might have been a distraction to the athletes here, but that doesn't seem to be the case. one athlete told us many of the u.s. athletes are just wanting to focus on their competition and not get distracted. that seemed to be the case on wednesday that this hasn't really had any impact. we saw a clean sweep for the women's 100-meet hurdles for the

united states. and in the women's long jump, they took gold and silver, as well. so it doesn't seem to be having much on an impact here. >> absolutely. of course, the brazilian authorities want to sort this out because of their reputation here. of course, in the days ahead, we'll learn much more on this. another big night for jamaican runners. usain bolt winning his race with ease. how did that all play out? >> reporter: he seems to be having far too much fun at these olympic games. he cruised to victory in the men's 200-meter semifinal tonight. laughing as he crossed the line. it gives us a bit of a him on what's to come thursday night. we've got the final and the fact that usain bolt wants to break the world record, his world record that he set in 2008. that's a time of 19.19 seconds.

in fact, he wants to go sub-19 seconds. his hopes of doing so were boosted today. who of his greatest rivals, justin gatlin from the united states didn't qualify. and johan blake, his teammate, didn't qualify either. so it's potentially going to be on the card later today. but he's going have to keep up, because his teammate on the jamaican team, elaine thompson, won the 200 meters tonight. >> what a day for jamaica, right? what about that gold, silver, bronze for the u.s. team, the 100-meter hurdles. what an impressive show that was. >> reporter: an olympic first, in fact. this is the first time that thee u.s. women have swept the medals in any olympic event. and they did so in style. it was brianna rollins who took

gold, and mia alley silver, all of them celebrating on the line together. fantastic pictures of their posing with the u.s. flag. >> yeah, that is a real kodak moment. thanks so much, christina mcfarland joining us live from rio. more than 1300 firefighters are battling a massive wildfire in southern california. in just a day, it exploded across more than 12,000 hectares. cnn is in san bernardino county where crews are desperately trying to get the flames under control. >> reporter: this blue cut fire has been erratic blaze for

firefighters to blaze because with the winds coming in, it's burning in multiple directions and it's also -- it has plenty of fuel as this is a really dry part of california. we've been under drought conditions for several years now. we were talking to one fire official, who was talking about the danger of these power lines. listen to what he had to say. >> those power lines are a huge concern for us. they have a high amount of electricity. hundreds of thousands of volts in those lines. it impacts our aircraft, makes it unsafe for them to fly above them. >> reporter: and those embers are a really big concern. thousands of people remain under evacuations. they're fight thing fire from the sky. also, crews are out there as well as bulldozers to battle this blaze. take a look at this right here. this is a school bus where the

fire has run through. unbelievable the damage, how the wheels have been burned out, the glass broken out by the blaze here. this is very devastating for the people who live here to see so much of what they owned burned up and destroyed. stephanie elam, cnn, san bernardino county, california. >> yesterday the fire was zero percent docontained, now 4%. >> containment is just minuscule. the terrain, the landscape has a lot to do with it. we've touched on how challenge thing is for firefighters. if you light a match, you hold it straight out, it burns gradually towards your finger, you give it a slope, it returns

very rapidly. look how many square miles of land consumed so far, about the same size of the city of san francisco, going from that to that in 1 1/2 days. the winds have not been helping out, 15, 25 miles per hour, that's the concern over the next 24. so improving conditions are going to be seen as far as humidity increasing, temperatures decreasing. but the top of these hills, these gusty winds come and move embers downstream. these embers are displaced and starting additional fires. so what is the temperature trend? at least that is good news. we drop below 100 degrees. some of the observation points are showing a 98 degree observation. those temperatures being about 37 or so celsius at this hour. shows you how hot it is. it's bone dry, of course, but extremely hot and windy, makes

it very challenging. >> that's exactly what's needed for fires. thanks so much. always a pleasure. donald trump says he's willing to do whatever it takes to win this election. so for the second time in two months, there's a major shakeup in his top campaign leadership. trump is lagging in the polls, something his attorney appeared unwilling to admit in an interview with brianna keilar. >> you say it's not a shakeup. but you guys are down, and it makes -- >> says who? says who? >> most of the polls, all of them. >> says who? >> polls. i just told you, i answered your question. >> okay, which polls? >> all of them.

>> more on the new trump operatives and what they mean for election effort going forward. >> i am who i am. it's me. i don't want to change. >> reporter: kiss the establishment good bye. donald trump is unleashed. >> everybody talks about are you going to pivot? i don't want to be pivot. you have to be you. if you pivot, you're not being honest with people. >> reporter: the gop nominee is shaking up his campaign yet again, setting the stage for a knife fight with hillary clinton. >> hillary clinton doesn't have that strength or stamina, believe me. she cannot win for you. >> reporter: trump bringing on stephen bannon from breitbart news. and senior adviser kellyanne conway to campaign manager. unconstrained by advisers urging him to become more palatable to

the republican establishment. despite his poll numbers, a source tells cnn, trump still believes he has a chance to win. and if he loses, he wants to at least win his campaign on his own terms. this puts trump at the center of the circle of advisers. all known for their no holds barred tactics. sour hillary clinton seized on it as just another reset. >> donald trump has shown us who he is. he can hire and fire anybody he wants from his campaign. they can make him read new words from a teleprompter. but he's still the same man who insults gold star families, demeans women, mocks people with disabilities, and thinks he knows more about isis than our generals.

>> reporter: but the intrigue from trump tower overshadowing trump security round table today, and the message he hoped to drive home this week. >> i will be your champion. i will be your voice in the white house. we will bring it back. we will once again be a country of law and order. >> reporter: paul manafort made it clear that he's not going anywhere. he sent around a memo that says, i remain the campaign chairman and chief strategist providing the big picture, long-range campaign vision and working with all of you to implement our strategy that will guide us to victory in november. and kellyanne conway, the new campaign manager said this evening, that it was all them making the decisions. sar a murray, cnn, new york. joining me now to talk more about this is josh rogan,

columnist for "the washington post." thanks for being with us. >> sure. >> donald trump's campaign says this is not a shakeup. if it's not that, what is it coming just three months before the election and what do you think it signals in >> there's just no doubt it's a shakeup. there's no other way to view this. when you have a new campaign executive and new campaign manager 82 days before the election, that's what a shakeup is. we wouldn't expect them to admit it's a shakeup. but it indicates that trump himself realizes that he has a problem. we've seen in recent days and weeks donald trump himself remark that he believes that the campaign is going in the wrong direction. he talks about how it might be rigged, he blames the media for his sagging poll numbers. but this is not a move you would make if everything was going well. so donald trump acknowledges the problem, this is his plan to fix it. >> it is an interesting move, though. what does executive chairman of

breitbart news, steven bannon, bring to the trump campaign and how might he change the direction of this campaign? will it help him in the end? >> sure. what does steve bannon bring to the table? he brings an attack dog mentality, a political fearlessness that comes with taking risks and saying things that are outside the bounds of normal political conversation. that's what breitbart news is. it's a political hit machine, an attack machine, sort of posing as a news site. so what that means is we can expect the trump campaign to go on the offensive and just to go increasingly negative. they were already pretty negative. will that help them? it remains to be seen, but i don't see personally how this aids him with the voters that he should really be appealing to at this stage. independents, young voters, moderate voters, minority voters. none of those people will be

encouraged by this move. what it signals is that donald trump is doubling down on his commitment to his core voters, we're talking about the people who have been with trump, who believe what he says and who got him through the primaries. it's an inward looking, narrow he focused strategy and a risky one at that. >> what we saw, and it was just tuesday night we saw trump. he was following prompter, staying on message. that apparently -- they decided that hasn't worked. they want trump being trump. so can that -- and you mentioned going negative here -- how is that likely to improve his numbers? >> well, i don't think it's likely to at all. the bottom line is, trump has been divided between two camps, both inside and outside his campaign. one camp that wants him to join with the greater republican establishment and appeal to a greater range of voters. one camp that wants him to stick

to what he's been doing this whole time. if you listen to what trump says directly, he says he doesn't care about unity or the rest of the republican establishment. so that's his decision. how it expands his appeal, no one has been able to sman. what it shows is that trump is committed to the strategy, that he's not going to change what he says, what he's reading from a teleprompter or not, the question is what is on that teleprompter. it seems he's decided to project a message that's largely divisive and along the lines of what we've seen so far. >> josh, appreciate it. and next here on cnn, meet the cajun navy, a group of volunteers rescuing people from the deadly flooding in louisiana. they could be the nation's most important neighborhood watch group right now. north korea says it plans to keep up its nuclear tests as u.s. officials share growing concern over the progress of the regime's weapons program.

the details still to come.

this is cnn breaking news.

this just in to cnn. breaking news out of eastern turkey where a large blast has rocked an area near a police station. turkish state media report many ambulances went to the explosion site, but no word on how many people may have been wounded or perhaps killed or who may have been responsible. we will, of course, follow this story and bring you the details as they come to us here at cnn. the red cross says the widespread flooding in louisiana is likely the worst natural disaster to strike the u.s. since super storm sandy in 2012. right now the death toll stands at 13. the latest victim was a 93-year-old woman who died while her neighborhood was being evacuated. more than 40,000 homes have at least some kind of flood damage, that's according to the state's governor. he's asking for volunteers to

clean out mud from those homes. louisiana has absorbed an astonishing 6.9 trillion gallons of rainfall in a week, enough to full more than 10 million olympic-size pools. first responders are frantically working to make sure residents are safe and secure. cnn's rosa flores asked one rescue worker to reflect on the work he's doing. >> you can see back behind you, a lot of the water hasn't receded yet and we have to keep going in and out. every house has to be checked. we will check them, our other teams will come back and check them. probably some fema team also come in here and check every house. we have to make sure we don't leave anybody behind and everybody is accounted for. >> those first responders are getting help from a group of good samaritans. they call themselves the louisiana cajun navy.

and they've been searching the flood zone with their own fishing boats. we're joined by one of them now clyde cain is the organizer of the cajun navy. thank you for all the work you've been doing on this. it is a tough job. talk to us about just how hard it's been to get out there and help the first responders and describe to us the extent of all the damage you've been seeing. >> first of all, the extent of the damage has been overwhelming. a lot of the areas or most of the areas that are affected are not considered flood zones, so we're dealing with folks that are out there, so the devastation afterwards is going to be greater. if our parish, our sheriff's department and volunteer departments are overwhelmed because of the amount of rain and devastation, which left a

lot of smaller areas that needed attention, which is where we come into play. we come in and we try to organize and take over the areas that are just getting zero response, and get out there and get people in before tragedy happens and before anyone can fete over to them, we try to be first responders for that. we've been loosely organized over the years, but it's now we're pulling it together under the louisiana cajun navy and organizing it. >> what do you think of the major challenges of the cajun navy and the first responders have had to deal with so far and going forward? >> just being able to, i guess, work alongside the volunteers, we're working on that right now, being able to be qualified with them, checking our boats in. the worst part is turning people

away that want to help. there's just too many boats or it's just getting unorganized. >> of course, what is going to happen to all those people who have lost their homes and what about the 40,000 houses that have been damaged by these floods with mud and rain? >> well, we have lots of people on the ground, lots of volunteers. lots of churches are coming together. we're staging back over in my area, we're feeding those that are coming out of the flooded areas, we're feeding them hot food. they're starting to gut houses. you would be amazed how quick everyone cleans it out. the absence of any division here has been the most exciting and overwhelming thing to see. just as katrina, everyone helping everyone, it's not a color or a race, you're a person in need and just the camaraderie

and the coming together of our state as we always do. and just the absence of racism and the absence of just anything we're a human race and everybody needs rescued. it took a flood, but just the absence of all of that is so relieving, it's taking pressure off of us. it really feels good to go out and everybody helping each other and just sharing those moments of camaraderie. >> it is certainly heartbreaking for so many of these families who have lost their homes and they're not insured. clyde cain, thank you for talking with us. we appreciate it. there are big changes at the top of the trump campaign. coming up, what the opposition thinks about it. and one of north korea's top diplomats desert his country for south korea. just ahead, the details on pyongyang's latest p.r. problem. back in a moment.

and a very warm welcome back to our viewers here in the united states and around the world. i'm rosemary church. a lawyer for two u.s. swimmers says they have been ordered to stay in brazil until they make a police statement over their allegation of being held up at gun point in rio. brazilian authorities pulled the swimmers off their u.s.-bound plane wednesday night. crews are desperately fighting a wildfire in southern california that's forced thousands of people to evacuate their homes. this time lapse video shows the

blue cut fire. it erupted on tuesday and quickly exploded across more than 25,000 acres or 10,000 hectares. in eastern turkey, a large blast has rocked an area near a police station. turkish state media report numerous ambulances went to the explosion site. three people are dead. ben wedeman joins us now from istanbul with more on this. it is not long after this blast, of course. what information are you able to tell us about this? >> reporter: this is the fifth such bombing in the last two weeks, rosemary. we understand the explosion went off outside this police station in elazig around 8:00 in the morning local time. that's 2 1/2 hours ago. that's the time that there's a lot of people on their way to work. now, it's not clear what sort of

explosive it was. was it a car bomb or something else. but we understand from turkish authorities that hundreds of people have been wounded. cnn turk is reporting three people killed, but it's still early. so that's probably not the final death toll. as i said, this is the fifth such bombing in the last two weeks. and recently, a pkk leader, that's the kurdish worker's party, which is engaged in a low intensity war against the turkish state, he threatened turkish police saying that they will not be safe in turkish cities, in the center of turn irk centers. it is believed that this is the work of the pkk, though they've made no claim of responsibility until this time. >> ben, you're there in turkey, in istanbul, of course. as you mentioned, the fifth bombing in the last two weeks. what is the sense there, how are

people feeling in this sort of environment, and of course, the political unease that's there, as well? >> reporter: well, it's been quote some time that this wave of bombings began, going back really to the middle of 2015 with the last turkish election. since then, the situation has deteriorated. as far as the once sort of peace process that collapsed between the pkk and the turkish government, since then, these explosions have happened. they've been focused largely in the central and eastern part of the country, where there is a significant kurdish population. in istanbul, the concern is more related to the kind of attack we saw at the international airport with a bombing there attributed to isis. rosemary? >> many thanks to our ben

wedeman reporting from istanbul in turkey just after 10:30 in the morning. many thanks. hillary clinton says donald trump has shown america who he is, and it doesn't matter who is running his campaign. joe johns reports the democrats are trying to use the republican nominee's campaign shakeup against him, as more questions surface about the clinton foundation. ♪ >> reporter: riding high on new polls showing big leads in virginia and colorado and tied in iowa, hillary clinton arrived in ohio today in full attack mode. leveling attacks against donald trump once again, calling out the billionaire businessman over his failure to disclose his tax returns and repeating the accusation that his tax plan would give the trump family a benefit of $4 billion. >> he's even created a new tax loophole that we call the trump

loophole. of course, we have no idea what tax rate he pays, because unlike everybody else who has run for president in the last four or five decades, he refuses to release his tax returns. so the american people can't really judge. >> reporter: and behind the scenes, clinton's campaign manager was blasting the trump campaign for the shakeup, saying -- >> donald trump has desided to double down on his most small, nasty, and divisive instincts by turning his campaign over to someone who is best known for running a so-called news site that peddles divisive, at times racist, anti-muslim, antisemitic conspiracy theories. >> reporter: a reference to breitbart news chief steve bannon who has taken over the trump campaign.

>> donald trump has shown us who he is. he can hire and fire anybody he wants from his campaign. there is no new donald trump. this is it. >> reporter: the turmoil in the trump campaign distracting from mrs. clinton's own troubles, including new details that shortly after she stepped down as secretary of state, the state department expressed interest in a nigerian land deal. gilbert has given over $1 million to the clinton foundation. the property in question was one on several of a list of properties the department was considering for a consulate. ultimately, the deal never went through. the continuing controversy surrounding the foundation and the inference of play for pay, which the campaign has denied, prompting "the boston globe" to write that mrs. clinton shut it down if she's president, saying the conflict of interest was obvious when hillary clinton became secretary of state in 2009. if the clinton foundation

continues to cash checks from foreign governments and other individuals with a pek, it would be unacceptable. the clinton campaign said there was no quid pro quo. the deal never happened and blasting citizens united, the group that brought the latest information public. joe johns, cnn, cleveland, ohio. joining me now to talk more about politics is larry sabato, from the university of virginia. great to talk with you, sir. so less than 12 weeks from the presidential election and donald trump and hillary clinton are dealing with numerous issues for their campaigns. so let's talk first about the latest polling numbers. what are electoral map predictions indicating at this point? >> hillary clinton is doing better than at any point yet in the campaign. my own electoral predictions have her now at 348 electoral

votes. you only need 270 to win. that is not including the normally republican states of arizona in the west and georgia in the south. both of those states are toss-ups, and hillary clinton and donald trump are tied in what should normally be a ten-point or so republican state. >> now, what's your sense of why it's at that point, why there seems to be so much more support for hillary clinton and not for trump, what has happened on the trump side to have that sort of slump in his support? >> well, i think you have to start with the fact that all of the things taken together that donald trump has said and done has left many americans, probably most americans, thinking that he's unqualified for the presidency. and temperamentally unsuited to sit in the oval office. that's pretty basic, rosemary.

if you can't overcome that, you're not going to win, no matter what problems your opponent is having. and then i have to add also, the demographics in america are moving very strongly in hillary clinton's direction. she's winning a massive majority. in fact, a record majority of all minorities in america, and they're 30% of the voters. >> and the trump campaign doesn't accept a lot of the poll numbers. what about these changes that were made at the top of the trump campaign, management structure? how is that going to help him, given it appears to be heading into a more conservative direction than before? >> i followed presidential campaigns for almost 50 years and i've learned one thing about campaign shakeups. winning campaigns don't do them, and losing campaigns do. the hillary clinton team has remained stable throughout the entire campaign.

donald trump has had three different campaign structures. and this is his third, and we're only about 80 days from the election. >> right. and we're starting to see more problems for hillary clinton, of course, regarding her e-mails and the clinton foundation. is this hurting her compared to trump, is it going to? you're saying that those numbers show it's not. but going forward, do you think -- because it just won't go away for her, will it? >> it's not going to go away and it will continue to bedevil her, even if he's president. this is just a classic example of a candidate who is very lucky, because if hillary clinton were opposed by a moderate, main stream republican candidate, i would predict flatly that candidate would be leading by about 5% of the vote. instead she's facing a very damaged republican candidate, and her problems just don't seem to matter very much by

comparison to his. >> larry sabato, appreciate it. >> thank you. and you can read more about the trump campaign and what's happened to it since the convention less than a month ago. it's all at cnn.com/politics. back in a moment. squuuuack, let's feed him let's feto the sharks!sharks! yay! and take all of his gold! and take all of his gold! ya! and hide it from the crew! ya...? squuuuack, they're all morons anyway! i never said that. they all smell bad too. no! you all smell wonderful! i smell bad! if you're a parrot, you repeat things. it's what you do. if you want to save fifteen percent or more on car insurance, you switch to geico. it's what you do. squuuuack, it's what you do.

north korea says it has no plans to stop nuclear tests as long as it senses threats from the united states. the regime also confirmed to japan's news agency that it has resumed plutonium production. this follows a high-level defection. cnn's barbara starr reports. >> reporter: it's the highest level diplomatic defection ever from kim jong-un's north korean regime. >> socialism is not something in the air. >> reporter: the deputy ambassador to the uk defecting

and reaching safety in south korea. last year, the ambassador appeared loyal. >> if you read our papers and the magazines and the photos, you can see how socialism is carried on and put into practice. >> reporter: a south korean government spokesman says the ambassador wanted out. >> translator: i am aware that he defected due to his yearning for liberal democracy. >> reporter: it comes as u.s. officials tell cnn that intelligence agencies are watching significant, new north korean military steps increase the threat to the u.s. and allies. >> they have been exceedingly active in demonstrating capability. >> reporter: the latest intelligence analysis concludes north korea is now aggressively testing medium and long-range missiles, warheads, and nuclear devices. and it no longer care it is the world sees its test failures.

>> when you have this many tests, you're eventually going to get it right. >> kim jong-un is trying to demonstrate he has capability, both in terms of the nuclear tests, as well as ballistic missile. >> reporter: satellite images reveal activity at north korea's nuclear test site, a canopy now blocks the spy satellite. rogue missiles difficult to track, has been tested, as have missiles that could reach alaska. the u.s. assumes that north korea has a rudimentary, miniaturized nuclear warhead. >> as soon as they have one test they can classify as an extreme success, we're talking a whole different ball game in their potential to threaten other sovereign nations in their area. but also potentially parts of the united states. >> reporter: the bottom line risk now, north korea is testing

all the weapons it needs to potentially launch an attack against the u.s. with little or no warning time. barbara starr, cnn, the pentagon. and now to a startling report on the crisis in syria. according to amnesty international, more than 17,000 people have died in prison since 2011. that is about 300 deaths each month. amnesty international also found that there were about 45 deaths each year in the decade leading up to the start of the civil war. the report says detainees faced beatings and electric shock. for a second straight day in the skies above syria, russian warplanes launched air strikes aimed at isis targets. bombers took off from an air base in western iran, as moscow pushed back on the u.s.

suggestion that use of the base could violate a u.n. resolution. russia says two command centers and an isis training camp were destroyed and more than 150 militants killed. but it is civilians as well that are the victims of air strikes in syria. even the most innocent have not been spared. new video of a young boy pulled from the rubble after the bombing is a heartbreaking reminder of the human cost of war. ♪ ♪

it has been nearly two months since the uk voted to leave the european union, a shocking move that rattled markets and weakened the pound against the dollar. since then, american tourists have flocked to the uk to take advantage of the exchange rate. >> reporter: for this family, visiting britain from california, brexit has had its benefits. >> it's definitely cheap eer. >> reporter: have you found prices reasonable. >> the prices are definitely reasonable. >> reporter: the fall in the pound means that the dollars now stretch further and their holiday is more affordable. >> we have tickets to see a play in london on friday night. we are going to see the harry potter studio tour on sunday

to be $16 more expensive. that means that booking early isn't good for the budget. >> i made the mistake of booking a t a lot of this stuff just before the vote for brexit, so i paid a little more than i could have. but yeah, it will help tourism. >> reporter: london's mayor is determined his city shows them a good time. >> what's really important is that the world knows london is open. we're open for visitors, we're open for innovation. we're the best place in the world to come for a holiday. >> reporter: which means for tourists, sterling stump may be brexit's silver lining. >> there you go. a possible holiday destination. i'm rosemary church.
