i'm excited to lead the organization. it's a new mission. >> to find out more about the veterans community project go to cnnheroes.com and while you're there, nominate someone you know to be a cnn hero. our coverage continues. a new development on the british oil tanker captured in the strait of hormuz, iran claiming that it seized the ship following a fishing accident. walking back the walkback. donald trump you now says supporters at his rally this week where people chanted send her back are great patriots. also -- >> small step for man, one giant leap for mankind. >> the moon landing. 50 years on, an amazing sight there. you'll hear from one of the men who was on the mission. one of the greatest

accomplishments. just so fun to be celebrating this, isn't it? >> gives you chills. >> welcome to our viewers in the u.s. and around the world. i'm natalie allen. >> and i'm george howell. from cnn world headquarters, "newsroom" starts right now. we are getting a new explanation from iran about why it seized a british flagged oil tanker in the strait of hormuz. iran says it captured the investigational after it was involved in an accident with an iranian fishing boat and ignored a distress signal from the boat. >> an iranian news agency reports the tanker is now in port and all 23 crew are to remain on board during the investigation. the british foreign office is advising all uk ships to avoid the straightt of hormuz and tha there will be major

repercussions if the situation is not resolved quickly. >> this is completely unacceptable. freedom of navigation must be maintained. we are absolutely clear if this situation is not resolved quickly, there will be serious consequences. >> u.s. officials say iran also seized a second ship but iran's military denies that. it says that it did stop a second ship briefly, but it was released. the ship's owner confirmed that it was no longer in iranian waters. in washington the view from the u.s. president is i told you so. >> we'll be speaking with the uk. and this only goes to show what i'm saying about iran. trouble. nothing but trouble. and remember this, the agreement, ridiculous agreement made by president obama expires

in a short period of time. it was a short term agreement. when you're dealing in countries, you have to deal in 50 years and 100 years. you don't deal in the short term. that was a ridiculous agreement. and it goes to show you i was right about iran. >> let's get a complete look at what is happening now with cnn's jomana karedsheh following the story live from istanbul and also our journalist from tehran, iran. good to have you both with us. jomana, what are you hearing more about why the tanker was stopped? >> reporter: well, george, initially what we heard from the iranians is that therapy saying that the british flag tanker violated known procedures, that it entered the strait of hormuz through the northern exit point, that it did not respond to multiple warnings. and therefore it was taken to iranian coastal waters.

now, in the past couple of hours or so, we're hearing through iranian state media quoting an official with the provincial maritime and port authority there saying that there was some sort of a fishing accident, saying that the british flag tanker had entered the strait of hormuz in the wrong direction, it collided with a fishing boat. when the fishing boat tried to communicate with it, it did not respond. so this fishing boat had to report this to the port authorities. and they say under the direction of the iranian revolutionary guard, the ship was taken to the port in iran. and under law the incident must be investigated and in the meantime the 23 crew member, indian and other nationalities,

including some from the philippines and russia, they must remain on board while this is being investigated. so while iranians are saying this was some sort of a fishing incident, if you look at other events in the past week or so, it is looking more like some sort of a retaliation because, you know, you had another british operated tanker yesterday that was seized for a short period of time according to u.s. and british officials before it was allowed to continue its voyage and then a few days ago, you had the iranians trying to impede the british tanker. and so the feeling is that is some sort of retaliation that the iranians promised for the seizure of their oil tanker, the grace 1, earlier this month. >> and it does seem to be one incident right after another.

i want your thoughts on the overall timing of this over the cows of course really of 12 hour, saying that there was an accident with a fishing boat, that is a very different narrative than stated earlier that could at least open the door for some discussion. >> yes, that is true. iran is deescalating what has already been escalated last night i can say. and the media outlets are coming back to the technicality of the damage and we have heard that the damage survey inspectors are rushing into inspect the damage inflicted on the fishing investigational and probably some mineor damage on the britih

oil tanker. bear in mind that this british oil tanker is a much smaller in capacity in size and everything than super tanker iranian. so it is not comparable to the super tanker. and at the same time, hard liners or conservatives if you like media outlet, they are just emphasizing that there was a fishing vessel accident. and so the damage was collateral. and it seems that they are emphasizing that there was a danger of dumping crude oil residue in the sea and pollution violating the environmental law. and also maritime law because

the british oil tanker was in wrong pattern movement. and so it is technicality. and that technicality means deescalating at this moment. from iranian side, deescalation has started. and bear in mind iranian diplomats are de-- we have seen the dexterity in the past to indicate that there is a flare of tensions and then they try to flare down. so this is why we can say -- >> to your point there, explaining -- >> this is why we can say that -- >> i think that we're having a technical issue there hearing

you. but we appreciate you being with us giving us sort of the indication that you are hearing from in tehran. and jomana karedsheh following the story for us live in istanbul. thank you both. although the uk is stressing diplomacy, cnn has learned that president trump has privately adopted a more hawkish tone. >> abby phillip has more on that story. >> reporter: when president trump spoke to reporters today outside of the white house, he struck an even tone about the provocations from iran in the region. he emphasized that the u.s. would be talking to their british counterparts and the ships that were seized were not americans leading some to wonder whether all of this was enough to cross his red line. but we're also learning privately sources say that president trump is moving away from the idea that he can talk to the iranian regime and use diplomacy to ease tensions. authorities say that he has

become more hawkish after iran has batted down his attempts to open the door for diplomacy. that has worried some of the president's allies who believe that it would be a big political mistake for him to engage in military action against iran. but we still don't know as of this hour whether the president believes that these latest seizures of the two oil tankers in the region are enough to prompt military action. but it does seem that president trump is no longer talking -- at least not talking as much about talking about iran as he has in the past. and that could very well be because iran has said that they are not interested. abby phillip, cnn, the white house. a day after distancing himself from racist chants at a rally, the u.s. president donald trump is calling his audience incredible patriots. >> this caps a week of criticism against four minority female house lawmakers that all started with a tweet. pamela brown has the details.

>> reporter: tonight president trump has gone full circle, again defending his racist attack against four congress women. >> they call our country garbage. i don't care about politics. i don't care if it is good or bad about politics. you can't talk that way about our country. not when i'm the president. >> reporter: and defending his supporters. >> send her back, send her back! >> reporter: who chanted send her back. >> people in north carolina, that stadium was packed. it was a record crowd and i could have told it ten times as you know, those are incredible people, those are incredible patriots. all right this despite concerns raised from aides including his daughter. but today the president down played their involvement. >> they didn't advise me. >> reporter: vice president pence also taking heat from republican lawmakers over the inflammatory chant. and there was the president's attempted cleanup on his own yesterday. >> i was not happy with it.

i disagree with it. but again, i didn't say that. they did. >> reporter: but now trump is back where he began, retweeting his previous tweet asking for the congress women to polle guise to our country. and threatening democrats that he will carry this fight to the ballot box in 2020. and after congresswoman ilhan omar returned to minnesota for a town hall -- >> feel goods to be home. we will continue to be a night mayor to this president. because his policies are a nightmare to us. >> reporter: trump tweeting today that the welcome was a, quote, staged crowd. >> i'm unhappy when a congresswoman goes and says i'm going to be the president's nightmare. she's going to be the president's nightmare. she's lucky to be where she is. let me tell you. and the things that she has said are a disgrace to our country.

>> reporter: the chant fallout spreading to the international stage too. german chancellor angela merkel telling reporters i distance myself from this decidedly and stand in solidarity with the women who were attacked. and justin trudeau denouncing the comments. >> i want everyone in canada to know that those comments are completely unacceptable. >> reporter: and british prime minister theresa may also calling trump's language completely unacceptable. >> hopefully we're in good shape on the debt ceiling. >> reporter: the president also taking a firm stance on the debt ceiling telling reporters that democratic leadership shouldn't use to negotiate. >> i can't imagine anybody ever thinking of using the debt ceiling as a negotiating wedge. that is a sacred element of our country. they can't use the debt ceiling to negotiate. >> reporter: changing his tune from 2013 when president obama was the one facing a debt ceiling crisis. >> the debt ceiling is a

powerful weapon. i think that is a powerful card. >> and let's bring in inderjeet parmar in london, a frequent guest. good to have you with us. >> thank you. >> first up, president trump targeting these women in congress, progressive democrats, in denigrating statement, his audience cheered and then i backed off and said he didn't like the chanting and now attacking the congress women and calling the crowd patriots. is this a pattern we've seen before from him in other conflicts, the back and forth, what do you make of it? >> as you said, this is a recurring pattern. president trump has put out right front and center if it wasn't clear already that race, the immigrant, the refugee, the people designated as unamerican or nonamerican, they are front and center of his campaign for 2020 much as they were in 2016.

really what he's trying to can is galvanize his own base which company heres most strongly around the message of exclusion and inclusion. that is who is a real american. is a real american a foreigner, an immigrant, person of color, a minority, or are they really just white americans only. and i think that is the kind of -- the divide that he is working on. and it is largely up to now been quite successful with his particular base. and he puts it forward, and he wants to keep the pot boiling because it has very powerful political consequences as far as he is concerned. and i think that that balangalvs a lot of his base but it also alienates many and we'll see how that portends. >> and we just saw the international condemnation from world leaders to what he said

and he's hearing it from people in the united states. if he doesn't stop because he thinks this could help him, where will this go? is he tapping some to something dangerous, something that could rip into the social fabric of this country? >> absolutely. i think if you look at the kind of things that he said in regard to the four congresswoman and one in particular ilhan omar supporting al qaeda, supporting terrorists killing american soldiers even as trump was tweeting, this is an incitement to violence actually. and when we look at the violence in charlottesville, the shooting at mosques, the coast guard arrested with a cache of weapons, the mail bomber last year, there is a powder keg position in the united states and i think that he is constantly playing with fire on that front and he is willing to insight possible increases in political violence in order to

drive home his message. and i think that is the biggest problem. so if we look at some of the effects of this, you have pro nazi groups in the united states congratulating president trump for saying send them back and go back to your own country. and he is stlenkenning all of those kinds of elements and his rallies are increasingly raucous and violent in their tone and content. so he is in-flaflaming very dee divisions and they won't be easy to put back into any kind of a box on any short notice. >> absolutely. and you don't see a lot of republicans stepping out about it and saying very much. but one republican did say about the chanting, he said that it would send chills down the spines of our founding fathers. so interesting to see how far in trump takes this. always appreciate your insights. thanks very much. >> thank you. and we're just getting

started. the race to 2020. here we go. still ahead, scorching temperatures have put much of the united states on alert. we'll look at which cities are doing their best to beat the heat and how long the tough temperatures will linger. and also ahead, latest on iran's threat to commercial ship and why iran now says that it captured the oil tanker. ♪rocking the stage and we're never gonna stop♪ ♪all strength, no sweat... just in case you forgot♪ ♪all strength, no sweat... ♪no no no sweat... stwram. stram. stram. straichl

85% of the u.s. population will swelter through temperatures above 90 degrees fahrenheit. that prompted officials around the country to take measures to keep people safe from this very dangerous heat. miguel marquez takes a look at it. >> reporter: from new mexico to new england, intense heat. >> too old for this heat. >> reporter: nearly 200 million americans sweating it out. roads buckling from the heat in shawnee, oklahoma and haze kansas. in chicago, a thermometer interests a car hit 129.6 degrees. in washington, d.c., tore wris s tourists wiltsing in the hot air. deadly heat. this former nfl offensive lineman dead from heat stroke. young, elderly and those susceptible to heat gathering in cooling centers in new york

is 4:00 in the morning, feels like 90 degrees. so we have not cooled down at night. take a look at the heat warning, i'm counting seven states, the entire state is under a heat warning for heat that will feel like it is 105 to 115. and surrounding areas less so, but still a big deal. heat advisory between 100 and 105, that is when you factor in the temperature and the humidity. because that is what it feels like to the body. the air is rising, hits a lid, comes back down and warms even more. so that is the pattern responsible for all of the heat. look at the overnight temperatures here, it is currently feeling like 90, i showed you in d.c., 89 in new york, 89 boston. possibly hearing 100 record morning lows. those are the nighttime temperatures that will be broken for very warm readings. this afternoon, it will feel 105 to 115.

and this continues sunday. but look at the numbers in chicago and minneapolis, what is going on there? well, a front will be moving in, it will bring us the potential for severe weather, but more importantly, you want relief, there it is heading into early next week along the 95 corridor, we'll go from 100 to temperatures in the 70s. >> and no one will complain. >> i don't think so after this relentless heat wave. >> all right. thank you. still ahead, protests still going on in puerto rico, thousands filling the streets, their voices heard. what they say that they have completely lost faith in, the governor and the government there 37. and more details about the suspected arson fire at a famous studio that left 34 dead.

let's update you on the story we're following this hour, the seizure of a british flag oil tanker by iran. iran says it captured the vessel after it was involved in an accident with a fishing boat and ignored distress signal. is this a day after the u.s. says that an iranian boat was destroyed when it came too close. >> and there have been numerous provocations, including the shooting down of an american military drone. the seizure of vessels and several attacks on commercial tankers that have been blamed on iran. >> a lot to talk about. and to do so, we have a senior research fellow from chatham

house with us. it is a volatile time in the strait of hormuz. we're seeing a more as ser difference iran at a time when the u.s. and uk ramping up their presence there. where do you see this going? >> it is indeed a volatile time. and i think that we should expect this action and reaction, tit for tat, response that iran continues to put out there in reaction to the american shooting down of a drone, in reaction to the british seizing of its tanker in gibraltar. so this is classic iranian escalatory behavior designed to show that it can also push back. >> words here are very important. let's talk about those words and the timing of this over the course of 12 hours. iran now saying that the tanker was in an accident with a fishing boat. that is very different than the

words iran's revolutionary guard seize seized the vessel for turning off its tracker. >> is this a bit of iran's space where it can operate quite effectively sending out mixed messages. on the one hand, significant nosignificant -- signaling that it can be destabilizing and push back against the u.s. and uk in response to their perceived threatening behavior. but at the same time, iran also likes to operate in the space where it can deny and sort of obfuscate. so this is iran's strategy and it is playing quite well to the international community. >> the uk foreign secretary, we heard from jeremy hunt who said that there could be serious consequences. however that they are not looking at military options at this point. so what could serious consequences mean given that we are seeing ran and the uk, we've

seen them feud and this continuing back and forth now iran flexing its muscle? >> well, this is all very much tied to the british seizing of the tanker in gibraltar. there were talks that unfortunately broke down and this could pre-empty another round of discussions there and some sort of mediation to resolve that situation. but they also have to push back and the dangerous strategy here for iran is this could push the uk closer to the united states and result in greater coordination in the gulf between the two allies. and it could result in the uk leaning closer to the united states against iran with regards to the iran nuke agreement breaches and violations. >> with regard to the united states, we've seen the u.s.

putting pressure of course on iran with sanctions, but does the u.s. now find itself under pressure to avoid an all-out war and the u.s. president donald trump who backed out of that iran agreement, is he under pressure to somehow find a better deal than the landmark deal that was agreed to under the obama administration? >> yeah, i think that there are serious questions about the effectiveness of president trump's maximum pressure campaign because on the one hand, iran is definitely encircled and is looking for a way out of this current crisis. and we can see that through the multiple messaging taking place by foreign minister zarif, expressing willingness to talk, but they are liking for a face-saving solution. president trump also is looking for a face-saving solution. and they are both backed into a

corner. >> it does seem that they are backed into a corner and the volatili volatility continues. we'll have to see where it goes. thank you for your time and perspective. thousands of protestors in puerto rico are demand thagt governor step down from office, this is after hundreds of pages of leaked messages show him and his aides making sexist home know phobic comments along with threats to opponents and journalists. >> protestors say the leaks woke them up. nick paton walsh has this story from san juan. >> reporter: this is the sound governor rossello will have to get used to. for the second time central san juan, the old town, really shaken by the extraordinary protests. practices less maybe in the number by the end of tonight than we saw a few nights ago, but really further down we saw

thousands beginning a march in daylight and made their way peacefully up to here where we've seen an intensely noisy and some degree kite organized prote protest, now separated by barricades. but the momentum is building. the question many are asking, will the planned march for monday potentially hundreds of thousands of people brought out on to the streets from the morning until the end of the day, will this really increase the sense that maybe the governor here, his time is limited. his press secretary, the voice of the administration, offered her resignation today saying that she felt shamed when she was accused in front of her son of corruption and could no longer carry on in that public role. part of the house of representatives here is beginning to debate the process of impeachment. the sense that the time is changing. and governor rossello sounding

like he was going about his normal business and not really suggesting that he would heed the calls for him to resign. the question will be of course whether this growing sentiment is changing the political calculus around the governor. nick paton walsh, cnn, puerto rico. police say the suspect at the center of gentleman can pan's worst mass killing in almost 20 years has unspecified mental health issues. 34 people were killed in the suspected arson thursday at the renowned animation studio. >> the 41-year-old suspect told police that his work had been plagiarized and he used gasoline to torch the studio. police say they are not aware yet of a link between the suspect and the company. we're just days away from the hearings that democratics have been waiting for, robert mueller will answer questions about his russia investigation. how the democrats are preparing

for it, still ahead. and also a look at the trump administration administration's -- we'll be right back. sorry about that.

>>. for two years robert mueller avoided the media, but wednesday that is set to change. >> the former special counsel will face back to back hearings on capitol hill before two house committees. democrats are preparing questions that they hope clearly show the u.s. president obstructed justice. will that happen when mueller sits down? here is manu raju with more. >> reporter: lawmakers are intensely preparing for the most anticipated hearing in decades. when robert mueller testifies about his two year

investigation. democrats and republicans are holding mock hearings with top aides sitting in as mueller. cnn learned that democrats on the house judiciary xhe committee will focus on five areas of potential obstruction of justice laid out in the mueller report including trump's order to don mcgahn to fire mueller, his iftefforts to have mcgahn deny that the president ordered him to have him removed. and also the order to cory lewandowski to tell jeff sessions to limit the investigation to exclude the president and later threatening to fire sessions if he did not meet with lewandowski. and also episodes of alleged witness tampering, including trump encouraging paul manafort and also michael cohen not to cooperate with federal prosecutors. >> as he says it to the american people so they hear it, that will be very important. >> reporter: democrats plan to

press miller about the extent of russian interference in the 2016 election. and contacts between russians and the trump campaign and will ask mueller about his findings that trump publicly expressed skepticism that russia was responsible for the hacks at the same time that he and other campaign officials privately sought information about any further planned wikileaks releases of printed campaign emails. >> we'll ask him questions and expect him to answer. >> reporter: with the stakes enormous, democrats say they are preparing carefully, rereading the entire 448 page report. >> this is not going to be a whole bunch of members freela e freelancing. >> reporter: republicans plan to press the special counsel about whether his team was biased as well as anti-trump texts accepts by fbi agent peter strzok and attorney lisa page. >> we have a lot of questions about how robert mueller's team was assembled. >> reporter: and they plan to raise questions about why the investigation started in the first place.

>> basic questions, you have to understand where it started. >> reporter: but mueller has already indicated that he won't go beyond the four corners of his report. >> he will be impeccably prepared. he knows his stuff. >> reporter: and some democrats are trying to lower expectations including jim hines who told me he doesn't expect much news out of this hearing because of the expectation that the special counsel will simply stick to the report and other democrats are saying that it could drive more people toward the impeachment camp because of the special counsel even delivering the details from the report, people hearing it for the first time, their views could change about opening up an impeachment inquiry. so the question is whether someone like nancy pelosi, where she will come down. she has privately told her members that to approach it calm lir, seriously, don't raise or lower expectations. but at the moment expectations

still oppose opening up an impeachment inquiry even after the special counsel testifies. manu raju, cnn, capitol hill. and clearly it is unclear what mueller will say, but we know a lot of people will be watching to hear exactly how he describes this. so an interesting hearing. >> absolutely. well, we'll celebrate a milestone next. the world marking 50 years since humans first set foot on the moon. we look back at this defining moment in history when the u.s. sent men to the moon. you've tried so many moisturizers... but one blows them all out of the water. hydro boost with hyaluronic acid to plump skin cells so it bounces back... neutrogena® and try our hydrating makeup. i just love diving with my son... but diving can be really hard on my knees. move free ultra has been a game changer for me. within a week, i noticed a difference in my knees. taking move free ultra lets me do the things i love. everyone should try move free ultra.

one small step for man. one giant leap for mankind. >> one of the most famous sentences and it wasn't uttered here on earth. you've probably heard it before, those were spoken by american astronaut neil armstrong, first to step on the moon. m >> what a moment he and buzz aldrin made history by taking those first human steps on the moon and today the world is marking the 50th anniversary of the major milestone. let's talk more now with a retired nasa astronaut leroy

choi joining us from texas. what a moment, it opened imagination, inspired people around the world about the possibilities of space. and correct me if i'm wrong, but was instrumental in the trajectory of your own life. >> that's right. i was eight years old when we landed on the moon 50 years ago and that was an event that i can remember like it was yesterday watching an old black and white tv set and listening to the transcript missions coming back from the moon and hearing those famous words from neil armstrong that they had actually landed. that is what started the dream for me of wanting to become an astronaut myself. >> and of all the astronauts that you've spoken to during your career, your conversations with buzz aldrin, what has he told you about that particular mission and that moment? >> i've talked to buzz a fair amount over the years. and we talk about a variety of different things including some of his ideas on how we might go

to are mars a sarare are mamars that. but with the moon landing, 30 seconds of fuel left, they knew they had it made and they weren't too stressed out about it, so it was kind of interesting that what sounds like not very much fuel left, they fought that they were in good shape. >> what exactly would you say that we learned as a society, what did we learn from apollo 11? >> we learned that we can accomplish something like that. i think the whole world was amazed that we had actually done it. and the landing itself in many ways was much more complex than the walk. even as a kid, i was so impressed by going out later and looking at the moon and realizing out there almost a quarter of a million miles away, two astronauts were getting ready to walk. i even understood back then that the landing was the hard part. and once we landed, that these guys were going to get the chance to go outside and walk on

the moon. >> you know, you talk about these moments that really were just events, people would gather around the television. it was a primetime moment. and we don't have that quite as much. i've been showing my son pictures of the ap of the al po mission and it is the imagination, excitement and where we're see things go now, we're seeing the next frontier. nasa saying that we will go to mars. what do you think about that? >> i like it say that we've been 20 years from mars since 1969. thought that we would be on mars by 1990. of course none of that did come to pass. last time we were on the moon was 1972. the administration has called for a lumar lanar landing by 20. that is an ambitious time line

even if we did have the funding available today which of course we don't. so that is the challenge, getting the financial and political commitment from both sides of the aisle to do this program. but you knownoknow i think it i important to note that nasa is moving forward as best it can. the exciting part for me are the commercial efforts like spacex and blue origin that have leaders who either have the financial resources themselves or access to the financial resources to do their programs and they are driving forward, building rockets, building space crafts. and it is exciting to see if there could be a partnership, expanded partnership with nasa and see where it all leads. >> and we appreciate your time. thank you. >> my pleasure. thank you. everyone is getting into the celebration. tech giant google is paying tribute to the moon landing with one of their famous doodles on the google home page. >> and clicking it starts

animated video of the mission narrated by michael collins. here is how he described the historic mission for going. >> first time we saw the moon up close, it was a magnificent spectacle. it was huge. the sun was coming around it cascading and making a golden halo. it filled our entire window. as impressive as the view was of this alien moon seen up close, it was nothing compared to the site of the tiny earth. the earth was the main show. the earth was it. after an intense descent in which they almost ran out of fuel, neil armstrong and buzz

aldrin landed on the moon on july 20th, 1969. >> the eagle has landed. we'll step off the land now. one small step for man. one giant leap for mankind. >> neil and buzz set up an american flag that read hear men from the planet earth first set foot upon the moon july 1969 a.d. we came in peace for all mankind. >> and in our next hour, we talk with a reporter who covered the launch. and he was just 19 at the time. how about that one. >> spectacular to look back at that. thanks so much for being with us.
