the u.s. president calls it a set up, congresswoman tlaib says she's just changing her mind pl we'll have t mind. we'll have the latest. and plus the scene live in hong kong when demonstrate tore s are back on the streets.

and the paramilitary troops are keeping up the pressure. also ahead, 50 years since woodstock, they came together for sex, drugs and rock and roll, and they remember paeseac love and music. we're live from cnn world headquarters and we welcome our viewers here in the united states and around the world. i'm george howell, the "cnn newsroom" starts right now. it is 4:01 on the east coast. the u.s. president is slamming a democratic congresswoman after she turned down an offer from israel to visit her relatives in the west bank. earlier israel denied entry to representatives omar and tlaib at the urging of mr. trump. then israel offered tlaib permission to visit her elderly grandmother, but tlaib declined. that prompted the u.s. president to fire off this tweet, he says the only real winner here is

tlaib's grandmother. the president goes on to say she doesn't have to see her now exclamation point. the president's focus on congresswoman tlaib comes at a time of increasing volatility in the global financial markets. that is because the u.s. bond market this week flashed a warning signal that the american economy could be heading toward recession. that is not welcome news of course for the trump white house. kaitlan collins kicks off our coverage with this report. >> reporter: congresswoman tlaib is rejecting israel's offer to visit her family on the west bank, an offer that came with conditions one day after the country denied her and congresswoman ilhan omar entry at president trump's urging. visiting my grandmother under these oppressive conditions stands against everything that i believe in, tlaib explained on twitter. those conditions would have included a pledge not to promote boycotts against israel while she was there.

the president has faced widespread criticism forg gettig involved. >> it is disrespect for the congress and the american political system for our ally to keep two members of congress out of israel. >> reporter: but sources tell cnn the president's advisers believe his fight with four freshmen democrats who call themselves the squad could benefit him in 2020 which is why the president keeps hammering them on the campaign trail. >> it really is keep america great because we have these socialists want to take it away from us. >> reporter: the one message sources tell cnn advisors fear won't work out for him is the economy. shaky markets and unpredictable trade talks are stoking fears of a recession inside the white house. at a campaign rally overnight, the president struck a dire tone. >> you have no choice but to vote for me because your 401(k)s, down the tubes. everything will be down the

tubes. so whether you love me or hate me, you got to vote for me. >> reporter: with re-election on his mind, trump now finds himself defending the very policies that are rattling investors. >> and we're imposing beautiful well placed tariffs. >> reporter: even admitting that his trade war with china may not end quickly. >> i never said china was going to be easy. >> reporter: something he actually did say just last year when the president noted that trade wars are easy. now, the president is insisting that he thinks the u.s. economy is doing just fine. but our reporting behind the scenes shows that the president has a little bit of afternoon pre-henks becau pre-henks becau apprehension because peter navarro says that there will be an economic reare bound, and worth it in the end, but he is also turning to people outside the white house including a phone call today with three ceos of banks where the president

asked them what they thought and they said that there were negative side effects to the trade war and they want to be resolved as soon as possible. kaitlan collins, cnn, traveling with the president in new jersey. and let's put it into focus now with thomas gift. he is a political science lecturer at university cling ol in london. good to have you with us. >> thank you, george. >> the u.s. president clearly playing to his base, this continual hammering of the freshmen congresswoman. does the us versus them argument built around the squad, does it work in his favor in the lead up to 2020 do you surmise? >> i think that is very much a question mark. for donald trump it is certainly not entirely unusual for presidents of the united states to get involved in middle eastern affairs and even israeli politics. the real difference here is that, one, it is usually done in

private. instead this was done in a public tweet. and two, it is usually done to advance diplomatic american interests. in this case it was really done almost exclusively to benefit his own electoral chances going into 2020. he really i think wants to paint the entire democratic party as representing some of the views of rashida tlaib and ilhan omar. and he wants to create divisiveness within supporters of israel. so i think that is the political calculation that donald trump is banking on. >> so politics of division at play here, but what about the art of distraction. so as this story about these congress women, about israel and the u.s. president of course make headlines, what about the other big stories that are in the had did hes, the concerns about a weakening economy, gun controlli control a big issue here in the united states. >> i think you couldn't be more right. this is really a distraction.

and so there were negative economic signals coming out of the markets this week, in particular we saw an inversion of the yield curve in the bnd m bond market which is a way of saying that long term interest rates dip below short term interest rates which is a sign of choppy economic waters ahead. despite the fact that employment is still strong and in general the economy is chugging along, there is a lot of predictions being made that perhaps we'll be heading into a recession and maybe even before the elections in 2020. so these are all issues that donald trump i think wants to deflect attention from. >> and we've seen a foreign nation essentially punish members of congress who are the president's political adversaries. could bipartisanship, could that damage bipartisan support in congress when it comes to israel? >> well, one of the interesting things that actually came out of

this last week is that the american/israel public affairs committee which is a lobbying group that is generally supportive of israel, broold lb supportive, decided to break with netanyahu's decision and break with the president's urgings because they really want to see bipartisanship on this issue of israel. and they are afraid that cracks may emerge to the extent that donald trump continues on the same line of argument that he has been going so far. >> you touched on the economy a moment ago, but if a recession is around the corner as the indicators suggest, what would that mean for the president come 2020? >> well, of course that would be very bad economic news for the president. really we never see presidents get reelected during times of economic downturns, protracted recessions. the irony of course is that donald trump's policies in large

part are making this worse and creating even more apprehensions and fears among investors. and this is particularly true with respect to the trade war in china. he had previously committed to increasing and imposing tariffs of 10% on about $300 billion worth of goods, that was supposed to start in september. but he has delayed that now until december saying that he didn't want to be the grinch that stole christmas essentially. but it is interesting even when noting that, because beforehand, he had said, well, we can have this trade war, we can play hard ball with china, it won't have any negative impacts. to some extent he is acknowledging that this might actually be having negative effects on the consumer. >> we appreciate your time today, we'll stay in touch. >> thank you, george. moving on now to hong kong where pro democracy protestors are out on the streets at 4:09

p.m. there in hong kong. 11th straight weekend of these protests and the city is on edge. demonstrators have grown more chaotic, this march comes just days after clashes between police and protestors at the hong kong international airport. let's go live to hong kong with will ripley, he is on the ground there. and you've covered this extensively and you pointed out in the last hour that what we saw in the international airport really was a major shift. >> reporter: it was the kind of disruption that hong kong has never seen before. what hong kong has seen for many years is protests like this, ma peaceful with thousands of people who have assembled here within the last hour. these people are streaming by our location and they just keep coming. pan over to the right and you can see as we march here past the government offices, a very large numbering of people

shouting at the government offices, shouting at the handful of riot police who have assembled here keeping their distance. but you the question is how long will they be able to keep their distance and what will happen in the coming hour us and tomorrow when larger protests are expected here in hong kong. we know that mainland china has assembled the military police at the border not too far from where i'm standing right now, there are also thousands of chinese soldiers already stationed in hong kong at the people's liberation army gerri son. they have stayed out of the fray, they have allowed hong kong police to attempt to keep it under control. but this city and frankly mainland china will not tolerate acts of disruption like what we saw earlier in the week with hong kong's airport shut down for two nights. i think the question on a lot of people's minds here, certainly those not out marching, is what are these protestors, the small minority of them that are intent on disruption, what will they do next, what will they target

next. >> and the other question here, we saw these images taken from earlier, chinese troops staging so close to hong kong. what are people saying there given that the possibility that the military could move in across the bridge? >> reporter: it really depends on their point of view. i think the majority of people here in this city are ready for these protests to calm down. they don't want to see an escalation, continued disruption. the city has been doing this for 11 consecutive weeks and a lot of people are tired and ready to move on. but for members of this movement, particularly some of the younger people who stay after the official march like this ends and stay late into the night for an unauthorized type of protest that has turned darker and more violence in recent weeks with now police routinely using tear gas and pepper spray and rubber bullets and protestors hurling bricks, the city getting ready to deploy water blasting trucks if the

protests get out of hand, that l and we've spoken with them, they say they are fighting for the future of hong kong and their future. their freedom. and they feel that they have nothing to lose and that is a dangerous police to be fighting from when they are willing to stake anything on their livelihood and their lives.poli from when they are willing to stake anything on their livelihood and their lives. >> win ripley on the streets of hong kong, again 4:13 p.m. there. as you know and as we have seen as we get later into the evening, that is when we'll see how this particular demonstration plays out. will, thank you. we'll stay in touch. new developments about that iranian tanker seized off gibraltar and the u.s. justice department unseals a seizure warrant. plus dictator, missiles and the u.s. president. the white house down plays north

that iranian tanker that was captured off gibraltar from being released. the u.s. is alleging a scheme to support illicit shipments of oil by iran to syria. the grace 1 was impounded last month. gibraltar's supreme court ordered the ship to be released. ryan browne has details now from the pentagon. >> reporter: the u.s. government's department of justice unsealing a warrant where it said it sought to seize both the ship and the oil being carried by the grace 1 tanker which had been detained by gibraltar authorities after it was believed to be shipping oil to syria in try laviolation of sanctions. the u.s. attempted to seize the oil employer to the ships being released by gibraltar officials. gibraltar officials say they have assurances from iran that the oil will not make its way to syria and that the hundreds of millions of dollars of oil aboard will not go to any

sanctioned entity. xwib said it found evidence that the vessel was headed to syria before it was boarded by royal marines. the u.s. government's warrant says that iran had been using the oil and the grace 1 tanker to launder money and to violate several sanctions pertaining to terrorist financing as well as other money laundering entities. the u.s. sanctioned a wide range iranian government and military entities as well as those in syria and iranian-backed approximate sproxy groups. it is possible that the u.s. government believes that the oil and vessel were headed there. however gibraltar released the vessel before turning the items aboardoff to the united states government so it remains to be seen what the u.s. can do now to ensure that iran does not transport that oil to its forces or its allies in syria. back to you. staying with iran, the united states has new classified

imagery that it says shows iran preparing to launch a missile as soon as next week. iran claims that it will put a peaceful satellite into orbit, but the program uses the same technology that is needed for intercontinental ballistic missile, that is the same type of missile that could be used to strike the united states. the north korean government says leader kim jung-un directly oversaw friday's launch of what pyongyang says is a new weapon. the pentagon says the projectiles were short range ballistic missiles. they released kim in pictures celebrating there. more now from brian todd. >> reporter: after two more launches, sending ballistic missiles flying at six times the speed of sound toward the sea of japan, north korea's aggressive young leader appears to once again be trying to dictate terms to the u.s. and south korea from the tip of his speer.

the test firing of two short range missile he is late thursday is kim jung-un's sixth such provocation in only about three weeks. analysts say that he is clamoring for president trump's attention but also signaling his rage. >> the message is that as long as u.s./south korea exercises continue, north korea will continue to develop, deploy and test some new capabilities that can do damage to the united states, to our troops, to our bases and to south korea. >> reporter: those precision joint military exercises between u.s. and south korean forces started a few weeks agoducted i. officials say they are defensive, designed to sharpen troops' readiness. but the drills have always made the young self declared supreme commander of north korea's military uneasy. >> his rhetoric calls them preparations for invasion and to

strike against him particularly the purchase of the f-35 by south korea gives it the capability to strike deep and to strike any leadership target or any missile target in north korea. so he is afraid of this training. >> reporter: at the same time, kim is firing another diplomatic salvo at moon jae-in. kim's regime saying it has no desire to talk face-to-face with south korean officials again. this comes as president trump has soured on moon, believing that he hasn't done enough to reign in north korea's aggression. some believe moon is getting a bad wrap. it was moon after all who spurred a lot of momentum for the peace process early on, hosting kim jung-un's sister at the olympics and having an aide hand deliver kim's first request for a summit to president trump. but analysts say the dictator is conveniently for getting all of that. >> kim jung-un is trying to go

delegitimize moon jae-in, to undercut his political power in south korea, and most importantly to drive a wedge between the south korean and u.s. alliance. >> reporter: veteran diplomats are warning the president of the dangers of investing too much in his personal one-on-one relationship with a dictator who they believe wants to keep his nuclear weapons. >> indeed he does not intend to dedenuclearization rise. so a central danger is what i call self delusion. >> reporter: and to give an idea of how much the u.s. and south korea have bent over backwards to tolerate kim's provocations, analysts point out since that first summit in singapore, the u.s. and allies have canceled at least 12 sets of military exercises. and scaled back many others. while at the same time, kim jung-un hasn't scaled back any of north korea's military

bank to see her grandmother. congresswoman rashida tlaib said israel's restrictions on her visit were oppressive. mr. trump slamming tlaib calling her, quote, obnoxious. pro democracy demonstrators in hong kong are on the streets marching in force, 911th straight weekend that we've seen these protests. this live image right now at 4:29 p.m. there. hundreds of people came together and thousands are expected to come together to restore tranquility march. and more protests are planned in the coming days as the city is on edge, these clashes that we've seen between police and demonstrators have become more common. oscar nominated actor, writer and director peter fonda has died after battling lung cancer. he was the son of legendary actor henry fonda and younger brother of jane fonda.

as far as how real, i mean, it is not just how real, it is can he actually do it. the answer is probably no. >> reporter: no because despite trump's boasts about his business skills -- >> anybody read art of the deal? >> reporter: green land is owned biden mark a denmark and home to 55,000 people. and they have rich and valuable resources such as minerals, fish stock, seafood, renewable energy and a new frontier for adventure tourism. we're open for business, not for sale. but why does greenland which is 80% covered with ice matter anyway? that is a clue. greenland is a gateway to the arctic and as global warming opens the region to more exploration and traffic, a lot of countries are showing interest including china and russia. the u.s. already has its biggest northernmost military base there. >> it is located 750 miles north of the arctic circle which remains a critical area of the

globe in terms of our ability to thwart and defend against particularly russian threats. >> reporter: and history suggests this truly may not be a crazy idea. in 1867, the u.s. bought another huge cold place, but alaska has worked out pretty well for american interests and two times before u.s. officials have raised the notion of buying greenland. still, the outlook for about this real estate deal is not promising. it is not something that you buy or sell, if countries want other territories, it is war. next month president trump will travel to denmark to meet with the prime minister and premiere of green land. whether he will take his checkbook, no one knows. tom foreman, cnn, washington. once again president trump has gone through a shift on possible gun legislation. earlier this week following the mass shooting in texas and ohio and california, he claimed

problem that has to be dealt with. it is not the gun that pulls the trigger, it is the person holding the gun. >> well, it has been two weeks now since a racist gunman walked into a walmart in el paso, texas and pulled the trigger opening fire killing 22 people and since that day, in el paso the city has been filled with tears, heartache and kindness of strangers. that was on full display friday evening. take a look at the scene here. this service in el paso, texas, a 61-year-old man with no other family said good-bye to the woman that he loved. he didn't think people would show up, but hundreds of strangers came together around him. ea earlier he spoke with our gary tuchman. >> reporter: tony basco loved

if you had a spinal injection while on eliquis call your doctor right away if you have tingling, numbness, or muscle weakness. while taking eliquis, you may bruise more easily... and it may take longer than usual for bleeding to stop. seek immediate medical care for sudden signs of bleeding, like unusual bruising. eliquis may increase your bleeding risk if you take certain medicines. tell your doctor about all planned medical or dental procedures. what's around the corner could be surprising. ask your doctor about eliquis. hey! i live on my own now! i've got xfinity, because i like to live life in the fast lane. unlike my parents. you rambling about xfinity again? you're so cute when you get excited... anyways... i've got their app right here, i can troubleshoot. i can schedule a time for them to call me back, it's great! you have our number programmed in? ya i don't even know your phone anymore... excuse me?! what? i don't know your phone number. aw well. he doesn't know our phone number! you have our fax number, obviously...

welcome back to "cnn newsroom." officials in nepal want strict new rules to govern who gets to climb mt. everest. their aim is to prevent needless deaths by keeping inexperienced climbers and tour companies off the world's highest peak. bianca nobilo has details. >> reporter: images from may of the crowded mountain path, scores of clirmbers all clamorig to reach the highest peak. there were fatal traffic jams like these. and now nepal wants to keep it from happening again by changing who is allowed to scale the tallest peak on earth.

officials are formally proposing a series of restrictions on would-be climbers and tour companies leading expeditions. it is an effort to deter inexperience hikers and guides which experts told cnn at base camp in may contributed to the deaths and bottlenecks this season. >> they are super slow, they didn't have being technique about the mountains. looks like they have never been on the mountains. >> reporter: now many veteran climbers welcome a possible change in the lack of oversight and regulations on the mountain. >> it is about inexperienced climbers with inexperienced leaders. >> reporter: adrian summited mt. everest eight times and spent 12 years on the mountain. he easy is the number of people there has steadily increased, particularly as tour companies have few requirements for climbers. >> used to be somewhere in the vicinity of 10 to 12 companies guiding the mountain and most had years and years of

experience. and today i would guess in nepal there is 40 to 50 companies guiding on the mountain and many of them have come out of nowhere with no experienced leader, but seeing the opportunity of financial gain because there are no barriers to entry. >> reporter: the proposed changes suggest requiring minimum qualifications to get a climbing permit, including basic and high altitude training, a fee of at least $35,000. experienced climbing at least one over peak over 21,000 feet or 6500 meters high, and tour companies would need at least three years experience organizing high altitude compete expeditions. for expert climbers, the proposals may not go nearly far enough. but he says that they are a step in the right direction. that is, if they can be

executed. >> i want to believe it is possible. and i want to find ways to support my pal and the ministry of tourism in implementing these rules, but i think that it will be very, very difficult. the companies are the ones who will have to actually make these changes. and thus far we haven't seen the companies that interested in making the mountain safer. >> reporter: ultimately he says the onus may still fall to the climbers, a risky proposition on one of the most dangerous ascents in the world. bianca nobilo, cnn. and now from the cold peaks to the hottest month on record. >> yeah, we were sweating it out here in atlanta and across the world in fact, noaa just coming out with a bombshell report that says july was the hottest month on record globally, it was 1.71 degrees fahrenheit above the 20th century average. i'll tell you why you should

care. not only was it the hottest month, also the 415th consecutive month with above average global temperatures. this is just the latest in irrefutable warming trend that is being felt not only globally, but also locally. i'll try to break it down for you here. and the information that was involved in the noaa report regarding july of 2019. we know that it was the hottest month on record. lots of red on this global map. specifically in southern africa, alaska, into europe. you remember the heat waves that we talked about in europe. this is coming off of 2018 which was the fourth hottest year on record. and by the way, the top five hottest years of have occurred within the past five years. so does that alarm bells for you too? i believe so. we're seeing a trend here. and 2019 is on par to match the second hottest year on record which was 2017. and across the united states locally, we saw some incredible things happen in july concerning

things as well. warmest low temperature ever recorded, 84 temperature in miami, florida. sea surface temperatures across the pacific were on the rise. and in alaska, this is what really baffled scientists, we saw heat waves that unfortunately caused a die off in some of the salmon and trout fisheries. anchorage was 6 1/2 degrees above their average temperature for the entire month. and it was also across europe in celsius. fi five sfleparate countries record their hottest day on record. and get this, in sweden that particular country actually recorded its warmest temperature north of the arctic circle and that of course caused wildfires with heat like that. and it also had a detrimental effect on the arctic sea ice coverage which by the way is just under 20% below where it should be this time of year. in the month of july setting new

records, you watched it disappear right before your eyes, not only in sea ice volume but sea ice thickness. so what is actually happening? we are measuring the heat trapping gases, greenhouse gases, at record levels. something that the planet has not seen in 800,000 years. we have ice core samples, tree ring samples, biological data that gives us a glimpse into the past history across the globe. we've never seen co2 coffin s d concentrations this high. it comes from electricity, heat production, other land use. and the concerns, there is a link with a warming planet and specific weather trends like heat waves. >> all right. derek, thank you. and thank you for being with us for "cnn newsroom." i'm george howell at the cnn center in atlanta. that is a live image of hong kong. we'll continue to follow the demonstrations continuing into the 11th straight weekend.

more news right after the break. but we're also a cancer fighting, hiv controlling, joint replacing, and depression relieving company. from the day you're born we never stop taking care of you.
