world headquarters in atlanta, welcome to the viewers here in the united states and around the world. i'mally allen and this is cnn newsroom. and thank you for join us. our top story. u.s. president donald trump is mourning the loss of a man he called his best friend. his younger brother robert trump. president trump visited his brother there friday as he headed to new jersey over the weekend. here is what he said at a white house news briefing that day. >> from day one. it's a long time a go and he's in the hospital right now. and hopefully he'll be all right.

but he's having a hard time. >> cnn's kristen holmes is traveling with the president. here is her report from new jersey. >> reporter: president trump's younger brother robert trump passing away late saturday night, a night of president trump had gone on an impromptu visit to new jersey. we were told he was going to a hospital in new york to visit his brother robert. we knew he was seriously ill. not clear what illness he had. he had been in and out of the ho hospital since spring. and it's clearly an emotional and sentimental statement. he says it's with a heavy heart i share that my brother peacefully passed away tonight. he is not just my brother. he will be greatly missed but we will meet again. his memory will live on in my

heart forever. robert, i love you. rest in peace. you can see the strength of his relationship. president trump said that robert trump supported his candidacy for president 1,000%. it's unclear exactly what the illness is that robert trump passed from. we are waiting to hear more information from the white house. again, his younger brother who had been ill, passed away late saturday night. kristen holmes, christian, traveling with the president in new jersey. >> some of the president's children are tweeting about their family's loss. ivanka trump wroe wrote, uncle robert, we love you. you are in our hearts and prayers also. sources tell cnn president trump is expected to attend his brother's funeral. we are told the president personally dictated the white house statement about his brother. we turn now to the battle

against the coronavirus. and evidence that the world is still losing ground. the world health organize zigs has received reports on of a record number of new cases in a 24 hour period. more than 294,000. the figures from the u.s. are just as grim. more than 1,000 deaths reported for the fourth straight day. that brings the ugs death toll to more than 169,000. right here in the hard-hit state of georgia, the governor is letting some cities impose mask mandates. he says they cannot be enforced in private property or polling places. and they cannot fine places or violators more than $50. president trump took issue with comments from the covid crisis from one of his administration's top health

sfishls. dr. redfield, the cdc, warned recently that public health this fall in the u.s. could be one of the worst in american history. if people don't follow health safety guidelines. the president answered on saturday invoking the spanish flu epidemic. here is his comment but it's important to know that experts estimate 50 million people died in that epidemic. not what you are able to hear mr. trump say. >> no, i mean, you can't compare it to 1917, that was incredible. that was -- that was the worst ever by far. they lost possibly 100 million people. if you look at the numbers, they are coming down sub stasubstanl.

and now, more children are getting it. and more on how the virus is impacting children. >> reporter: that's right. new cdc guidelines that parents want to consider as they weigh whether or not to send their children back to school in the fall. the cdc acknowledging that children do transmit the virus in places like homes and summer camps. the cdc noting the number of cases among children is rising. 7.3% of all covid cases are among children. that is up considerably since cdc's last guide dance that was 2% for children with covid. also the cdc noting that the lower rates in children could be attributable to school closures to the early part of the pandemic. and given the new guidance, the

mayors and governors have plans to reopen. in new york, particularly, the governor last week announced that schools can reopen. here, we reached out to the governor here to see if the new cdc guidelines factor into the decision or change the plan at all. we have not heard back from them. but educators here in new york city, the largest school district in the country, now expressing a lot of unease about schools opening here and whether they have the right precautions and the right equipment to deal with the large influx of opportunities who could would b coming back to school here. it looks full speed ahead of school reopenings. back to. amid the pandemic, president trump continues to attack mail-in voting. during a saturday news conference, he repeated the unproven claims that an election

held largely by mail won't be fair of legitimate. >> we are going to have an election that takes place on a beautiful day, november 3rd. and usually at the end of the evening that i say donald trump has won the election. donald trump is your new president. whatever they say, you know what? you're not going to know this, possibly, if they did it right, for months or years. they ballots are all going to be lost. they're going to go gone. >> house democrats are considering cutting their summer recess short to deal with the growing controversy. the newly installed postmaster general louis dejoy has been criticized for changes he cently implemented. some workers say the changes have slowed down mail service by eliminating working hours and removing hundreds of sorting machines. the inspector general is

reviewing the changes as well as dejoy's ethics compliance. on saturday, bernie sanders tweeted this. the postmaster general must resign immediately. meantime, congressional democrats are speaking out about the impact on voters. >> i never thought that i would need to see the united states of america tolerate a tyrant who seems to just trample upon our constitution. john lewis would be so disappointed that he gave, nearly gave his life to vote for people of color, enter to watch the complicity of the republicans to hold on to this kind of shenanigans is just beyond me. >> so, the postal service finds itself in the middle of a

political controversy. and it's warning of delivery delays to come. here is cnn's sara westwood with more about it. >> president trump on saturday continued to cast doubt on the reliability of mail-in voting despite experts saying that widespread voter fraud in the u.s. is exceedingly rare, and many states have relied on mail-no voting for years and almost the postmaster general has made changes to the post office operations that sittic say will hamper the ability to mail in ballots, the president praised his efforts. hoe sought to draw a distinction with absentee. >> the democrats are not approvaling the funding for postal and not approving the funding for the thing they want to do all mail-in voting.

universal, you can call it. mail-no voting. again, absentee mailing is great. i am an absentee voter. i request it and i got it and i sent it in. that is what we had. now they want to send in millions and millions of ballots. and you see what's happening. they're being lost. they're being discarded. they are finding them in pile. it's going to be a catastrophe. >> absentee voting and mail-in voting is not black and white. both are conducted in the same way. ballots through the mail and only nine states are doing what the president is warning about. mailing every voter a ballot. in most states, people still have to request a ballot in order to vote. the president is exploiting the likelihood that the election result may not be clear on election night. because it does take longer to

count mail-in votes. the president tweeted the democrats know that the election will be a fraudulent mess. we may never know who won. meanwhile, the postal service warned 46 states and the district of columbia they are income partible. for example, some of the deadlines for requesting and turning in ballots doesn't leave the postal service time to get the ballots delivered. sara westwood, cnn, washington. meantime, president trump's challenges are preparing for the democratic national convention in the coming days. joe biden and kamala harris are getting ready to except their party's nominations. as cnn's jessica dean tells us, harris is bringing a lot of new energy and attention to the campaign. >> newly minted vice

presidential nominee kamala harris giving her first interview, and in the virtual interview, she is praising joe biden for having the audacity to put a black woman on the ticket with him. and going in policies and continuing to go back to joe biden really playing the traditional role as the vice presidential candidate, elevating the person at the top of the ticket that being joe biden. harris also continues to fuel an incredible fund-raising boost for the biden campaign. they rised $48 million over two days after her announcement. just a shock number considering that earlier in the campaign cycle, biden wasn't raising that in a quarter. they are rising it in 48 hours. harris and biden will be delivering the peach speeches right here in wilmington,

delaware. until then, it's a quiet weekend as harris and biden prepare. president trump had another chance saturday to denounce the birther conspiracy theory about senator harris. he said he could stot pursuing it and he did not dismiss it either. he continued to praise a controversial profess horse wrote an opinion piece for "n s "newsweek" questioning harris's eligibility. >> i know nothing about i. it's not something that bothering me. >> sir, when do you that -- >> i just don't know about it. it's not something that -- >> we will -- >> let met put it differently. let me put it differently. don't tell me what i know. let me put it differently. let me put it dimpbltdly.

to me, it doesn't bother me at all. i don't know about it. i read one quick article. the lawyer happens to be a brilliant lawyer, as you probably know. >> let's talk politics with natasha from england, to talk about what is going on here. a few months before the election. good morning to you. >> good morning. >> first up, i want to begin with the virtual democratic convention which begins monday. what do you expect from team biden and harris in the uncertain times in the country's history? can they generate excitement without an audience? do you think they will reach out to disenchanted trump supporters? >> right, well, i think with the up coming convention, usually it's about highlights rising stars, energizing the party, and i think the convention will be unusual in that it will be more about the latter two things.

really motivating and energizing the democratic base, but trying to make the case to the american public that the u.s. cannot handle another four years under trump, that the u.s. is facing eminent disaster and it's really biden and harris to pull the u.s. out of the mess, in particular because of the incredibly high enemployment rates and the mass spread of the virus. they are trying to make a case about what policies they need to pursue. and they are the team that can do so. >> kamala harris as the vp candidate has generated much excitement from democrats. what does he is bring to the ticket for joe bide snn what will be listening to from her? >> i think the choice is about trying to get energy to the campaign. and she has done that. we are seeing early polls, the most recent polls show that she

is helping biden. normally a vp pick doesn't help much. but it looks like she is doing well with both wings of the democratic party. hispanics, african-american voters and independents. she doesn't make a dent with younger people. she didn't do well with those who are 65 and older and not whites and general. but she does seem to give a lot of energy, and she really puts a contrast with biden who some think is very old and needs youth. needs someone who is young and also very capable. she is showing and that will be a very effective surrogate for biden. on the campaign trail, fighting for what he thinks is going to add to the presidency, and trying to appeal to a key democratic, an african-american democratic. this a key base.

and in 2008 and 2012, 66,000 afric -- 66% of african-americans came out to vote. and biden can pick someone who challenges him. who will criticize him. she showed it early on in some of the democratic debates. and by choosing kamala harris, he is demonstrating that he is willing to have people surround whoim don't always agree with him. >> thanks for joining us. >> thanks for having me. cnn will bring you live cove raj of the all digital democratic convention. it starts monday, 8:00 p.m. eastern time. and monday, august 24 thd, we will be covering the republican national convention. of course you can check out the

this is just outside of atlanta here in stone mountain georgia. opposing groups of protesters facing off saturday. one group, right wing demonstrators, many holding confederate flags. the other, a largest group of anti-fascist counterprotestors. local news reports protestors on both sides were armed. they were in stone mountain, the largest confederate monument in the u.s. no one was seriously injured or arrested. now we turn to belarus. president doesn't want foreign mediation to come in. he won't give up the country to

anyone. but he has reached out to vladimir putin. it started after a highly contested presidential election. tens of thousands of people have risked arrest, violence and alleged torture to demand him to step down. cnn has more from minsk. >> there are literallies thousands of people here. the way they protest, they stand apartment the side of the street, they have flags out, many with flowers and the motorists who come by, they honk their horns in support of the opposition, and in in country, one of the most oppressing in the world this is something that takes a great deal of sournlg. there are many people who were

arrested here since the demonstration started here last sunday after the election here. thousands of people were arrested and many were beaten in detention. people telling to us of torture in detention, and also people were par raided and humiliated on state tv. they are calling for the president to step down. it seems that is not something he thinks he has to do. in fact, he says he won the election by about 80% of the vote. he has already spoken to vladimir putin and still clinging to power. they are calling for a new vote and they are also calling for an end to violence by the police and other skurecurity instituti. wear on mask or you have explaining to do.

welcome back to the viewers here in the united states and around the world. i'm natalie allen. you are watching cnn newsroom. the world is still losing ground in the battle the against the coronavirus. the world health organization has received reports of a record number of new cases in a 24 hour period. more than 294,000 people worldwide. the figures from the u.s. just as grim. some 5.3 million americans have contracted the virus since the pandemic began. as you can see there, there have

been 169,483 deaths. mexico remains a covid-19 hot spot. it reported more than 6300 cases saturday and 600 deaths. overall, the virus has killed almost 57,000 people in mexico and more than a half mill infected. mexico signed a deal to make a potential vaccine next year and ship it to other countries. two of fran's biggest cities are enforcing mandatory mask orders for people out in public. paris and marseilles have been covid activate. harris reported 3400 new invexs saturday. that marks a post lockdown high for the fourth day in a row. let's go to cnn's jim bittermann live for us just outside paris.

you know, france was going in the right direction and all of a sudden, this. what happen do we know? >> reporter: exactly, that is that is worrisome for the authorities, four days in a row for the number of new cases but the numbers are increases, the rate of increase. there are 464 more team in the new case load in the last 24 hours as opposed to 170 the previous 24 hours. so in other words, the rate of increase is expanded and that really has authorities worried and they locked down, as you said, large portions of paris and marseilles, making sure that people are wearing masks out on the street. we have seen the police patrols out and checking people. and we will see what happens in the beginning of the week. already, the high authority of health here is warning people they should wear masks, and

indoor private settings with family and friends, and the laborman, she is going to talk to the labor unions this week to talk about wearing masks in work settings, and so all it looks like we are headed to another period of increased lockdowns on the country. natalie? >> yeah, and do you get a sense of how people are taking this? >> well, you know, you see -- the people we talked to in the mask wearing areas in pace yesterday seem to be pretty sanguine about it. there is a fair amount of acc t acceptance but people are pushing back. and in work settings, might be difficult for people to accept. on the other hand, i think the pre-eminence of the threat is clear on everybody's mind. and the fair amount of education has been done here in terms of how serious this is. i think the authorities will win

the battle. but it will still take c convincing. >> hope it works. thank you so much. jim bittermann for us. i am joined now by dr. peter dobach at the university of oxford. nice to see you, peter. >> good morning. >> we have been talking for months now about the cases globally, so many cases still on the rise. here in the united states as well. i want to begin though, since this is mid august, to talk about schools. now bringing children back in the classroom. we know cases among children are rising. some schools have already had to pull back. what are you expecting and what are your concerns as we head in the school season? >> well, natalie, as we have been talking about now, for some time, it's really difficult to imagine how we will be able to safely open our schools in settings of high transmission,

still covers most of the u.s. right now. schools do not exist in a vacuum. they exist in communities, it's going to affect schools. we have seen it in schools that fried to open early and many cases, they had to close. some kids and teachers were found to be positive. there is a lot we should have been doing for a long time to get ready for this. again, the number one thing we need to do is get ahold of this epidemic, and it's just not going to last. and it will be a very difficult situation as schools quickly start to close back down mncht. >> we are also seeing clusters in college dorms now, notre dame is one. university of north carolina, chapel hill. what is the challenge for colleges to limit the spread? and there is a threat to college towns as well. >> universities are actually really a special problem. we saw early in the outbreak

there were big clusters of cases in cruise chips. you remember seeing cruise ships stranded off the coast of the u.s. universities are similar. you have young people from lots of different places, all coming in one concentrated area, play staying in dormitories all at once. they will be mixing and socializing outside of the classroom. so there is a real risk that actually this could be a concentrated area for superspreader events that will effect students and staff of universities but the surrounding community in college towns and later when the student goes home to visit families, to continue the spread there. this is an incredibly difficult problem. that is why a number of them have decided to proceed with online instruction in the beginning of the term. >> well, the issue regarding schools and so many other entities in the united states is testing. which has lagged.

that is still a serious issue to try to control the spread. but the fda has now given emergency use to a saliva test created by yale that offers results in hours. is that promising? >> extremely. this is big news actually. one of the big missing pieces in the potential game changer is going to be rapid and cheap testing. we're doing nowhere near enough testing, and one of the sneaky things about the virus, so much of the spread happens to people with symptoms. we are going miss a bunch of transmissions. one of the big reasons the nba is able to get back to playing so successfully, is that everybody is getting tested on an extreme regular basis. and it turns out they were helping to validate the test by yale that can give a result within a couple hours and can be

done inexpensively. we think it may cost around $10. this is what we need to see more of. as people get back to work, in the office, you can get a test before going in. we can do screening for children and teachers to get back in schools. when it becomes ubiquitous that is a game changer. there are a lot of tests being developed. there is exciting. i hope the fda and the world health organization will prioritize approving more tests like this. >> yeah, i do too. we know how -- now it's not just people over 50 or 60 who are getting ill. younger adults can, and we continue to learn that the lingers issues from the virus are more varied and series than serious than doctors first realized. what are some of the persisting threats after a person recovers, peter? >> one of the big misconceptions

many of us have about covid-19 is a respiratory disease. if you survive it, you bounce back and get back to normal. that is just not the case. what we know is covid-19 is a vascular disease. it affects blood vessels. so maybe in about 10% of people infected with covid-19 with mild symptoms, initially, 10% go on to develop long term persistent symptoms. neurologic and mental health. and heart problems. we have seen heart inflammation in athletes, persistence, weakness, difficulty concentrating and this is lasting weaks and months after people recover from middle infection. we don't know what predisposes people to symptoms like this.

this is a systemic disease. and the effects may linger. kit be the polio of our generation. >> dr. peter, university of oxford, always appreciate your expertise. thanks so much. >> thank you, natalie. two companies from israel and the united arab emirates announced they are joining forces to come up with a covid-19 testing devise. it was announced in the terror group and apex testing company. they announced they with normalizing relas vegases. so hope there. in japan, officials are trying to manage covid-19 numbers without imposing a lockdown. so far, they counted on public condition shss to get through the pandemic. but it seems that the strategy is starting to backfire. here is more about it from

tokyo. >> reporter: the staff after the cafe are thankful the customers are back. it's hardly a full house. they know the bar will be open until midnight. this is the scene the government wants gone. convinced that night life is a big reason behind the surge in july. it has asked all restaurants and bars to stop telling alcohol at 10:00 until the end of the month. >> for what? it doesn't make any sense. that's why i declare that we don't follow that. we keep operating. as normal as possible. i don't like to -- i didn't like the japanese culture, they expect to you obey. >> reporter: he says it's more than a question of financial survival. >> are you putting the business on top of people's life?

of course not. it's like freedom. >> reporter: day after day of infections and those who are venturing out. >> translator: yeah, we should listen to the government but we cannot always swallow what they say. >> the government should pay us if they want us to act in retrants. >> reporter: and they are restricted in the ability to impose a lockdown m politicians and politics are worry about overreach, instead, japan has relied heavily on the mantra of the idea that one should hunker down for the collective good in charging times. >> the challenge is self-restraint, a sober reflection, so we saw it in the nuclear crisis. what is happening in japan, the people are gradually starteding to accommodate this. >> reporter: this pub owner says

he is trying to adapt. profits are gone. what is left is piling of raw fish with nowhere to go. i decided not to put up a fight. he has chosen to comply. by zapping this code, passers byes are encouraged to report stores who are not cautious enough. he says he is not taking chances. he can't afford to be ostracized. so he boards up when the clock strikes 10:00. cnn, tokyo. the western u.s. is sweltering this weekend and making conditions even more unbearable, several wildfires are raging in three states. we check it for you straight ahead. we support memorable moments, concentration - in hectic times . and focus to win the day.

several wildfires are raging in the western u.s. right you no, and things can get worse this weekend as an intense heat wave seers much of the u.s. nearly 100 million americans are under some form of heat advisory in texas, california, in the rockies and up the west coast to washington state. two of the most threatening wildfires in colorado have now grown in size over the past 24 hours. much to keep up with, and our meteorologist derek van damme can do it for us. he joins us now with more about it. hi there. >> hey, you know, some of the colorado wildfires that you just mentioned are so intense at the moment they are creating their own weather patterns. it's note as pyrocumulonimbus clouds. and this is satellite imagery

from space. and you can see the last few frames there, very intense clouds that raise way up in the upper atmosphere. 50,000 to 60,000 feet above the surface of the earth. check out the pine gulch fire, we are talking about 76,000 acres. and very little containment. in the westernest, the triple digit heat we are feeling. heat warnings, watches and advisories with the potential for over 100 record high temperatures for the period of today, right through the early part of next week. you add on top of that the extreme drought conditions, and the dark shading of red and orange from colorado to utah, and northern california, you have a recipe for broadcast disaster in including the violent fires that are blowing up, just outside of los angeles,

the lake fire, one we are monitoring closely. check out the video coming from the lake fire. this is about 15 miles to the northeast of los angeles city. this is a fire world. they are very turbulent wind conditions you are looking at here, intense rising heat, sucking debris and ash into what you notice is a tornado. it isn't. it's a fire whirl. it's mislabeled as a fire nado. they can last up to 20 minutes but they have winds that are capable of knocking over trees. 120 miles per hour. that is the same strength as a hurricane, for instance. intense stuff. they are creating their own weather phenomenon. >> all right, derek, thank you. with face masks now a vital tool in the fight against coronavirus, we ask are some masks better than others? you beat they are. university researches ers put

different styles of masks to the test and we'll show the ones that work best next. accident. he was tickling me and...

turns out, that i are not created equal. some do a better job than others. here is what cnn's randi kaye discovered. >> reporter: inside this lab in florida atlantic university, two processers are putting face masks to the test to see what are best at stopping the spread of coronavirus droplets. to find out, they fill this mannequin's mouth with water and glycerin. a pump forces it to expel the mixture, and a green laser captures the pop lets. we tested a handful of popular masks including this one with an exhall lags valve. people like the valve but the processers found that the valve allows droplets to escape. with a mouth with an exhall lags valve, it lets out all the

droplets through the valve. >> which makes no sense at all. >> it make no, sir sense. >> defeats the purpose. >> another popular mask faired poorly too. watch what happens when the mannequin talked wearing this linger layer. >> the gator is a surprising. it seems to let everything through. >> reporter: we also tested it for a sing the cough. we found it barely filtered the droplets. let's turn out the lights and simulate a. >> kevin:. they travel straightforward. next up is a bandanna made of cotton. >> what you see is the one layer mask performs a little better. you still get some leakage coming through. it filters some of the droplets but some escape through with a sing the layer.

they don't go very far. probably about six inches from the face when you are just talking. >> reporter: but the droplets travel about two feet and can accumulate over time in a room where people are gathered. this double layer mask made of quilten cotton also spread droplets when the mannequin talked and coughed but not as badly as 9 gator and bandanna. >> it doesn't go very far. probably two to three inches from the face. significantly better than the other mask. >> the double layer is in line with new cdc guidance suggesting two layers make the difference. and what about the blue nonsurgical masks so many people wear. they did well but there is room for improvement. when the mannequin talked, hardly any droplets were expelled but when it coughed, quite a bit leaked out the top. but still not much went through
