hear from one young woman who agrees it's toxic. ♪ and we begin in the united states with a search for the missing fiancee of gabby petito has expanded in a nature reserve in florida. it's been nine days since brian laundrie's family says they last saw him. according to his parents, laundrie said he was headed to a swampy 25,000 acre reserve in the town of venice. police have brought in specialized divers trained to recover evidence in low visibility bodies of water. meanwhile, a vigil was held for gabby petito in salt lake city on wednesday. petito's remains were discovered in wyoming over the weekend. a coroner has ruled her death a homicide. petito had been on a cross-country road trip with laundrie when she disappeared. cnn's randi kaye follows the route they may have taken on their way to a remote camping area in wyoming. >> reporter: so, this may have been how gabby petito and her fiancee brian laundrie drove their van to enter the spread creek dispersed camping area. we are 28 miles outside of jackson, wyoming. we just turned off highway 191 ask we're driving now on forest road 30290. if you take a look you can see the road is a gravel road and it stretches for miles into the camp site. remember, video blogger jen bethune and her husband captured a picture of this van they believe was gabby petito's inside the spread creek dispersed camping area. they posted it on youtube and gave it to the fbi. bethunes told us they spotted the van august 27 around 6:30 p.m., but the van was dark and they didn't see anyone near it. the video bloggers sent us the coordinates where they say they saw that van. we're trying to find that location right now. they said it was about 2 1/2 miles in or so, and the van was right on the road. this dispersed camping area is an undeveloped camping area that offers few services. it's a popular spot so it's no surprise gabby or her fiancee seem to have chosen it. it's on the eastern boundary of the grand teton national park and the views are breath taking. while we don't know for sure, this clearing could be where that van was parked certainly based on the distance we were given. it is right on the road, so nib walking by or driving by certainly could have seen a van parked here. otherwise it's pretty private. there's trees on the other side of the clearing. and then if you look out there, there's really not much other than some really big rocks and some gravel, and there's a creek that you can actually hear if you listen closely while you're standing here or parked here in this clearing. the forest where the campground is located spans more than 3 million acres. law enforcement has not said exactly where gabby petito's remains were found or what specifically led them here. but somewhere among all this beauty, something terrible happened. even though that campground has now reopened, there are still a lot of questions and the fbi is still seeking information. they are asking anyone with any information, perhaps they saw gabby petito and brian laundrie in those final days of august in that campground. they're asking that they come forward with information. they need to piece together what happened between these two and how gabby petito ended up dead. randi kaye, cnn, moose, wyoming. and the search for brian laundrie will resume in the coming hours. authorities say the specialized team of divers will return to the nature reserve. cnn's amara walker is following that part of the investigation. >> reporter: a search here at the reserve has ended for the night, and we are told that law enforcement will be back here to resume the search in a similar operation first thing tomorrow morning. as you said, an under water dive team was called out, they arrived at noon from the sarasota sheriff's department. they are usually called to search for evidence in bodies of water or victims in bodies of water. we don't know why they were called out, what they are specifically looking for. that remains unclear. the police say this is part of an overall search process and it doesn't necessarily mean they found something. i do want to note something very interesting because the search for brian laundrie here at the carlton reserve was actually called off on monday. that same day a search warrant was carried out by the fbi at brian laundrie's home. the fbi questioned his parents, and they were in that home for hours carrying out boxes of evidence presumably, also bags of stuff, and they also ended up towing a car. the next day on tuesday, they ended up announcing that the search here at the reserve was back on. so it's unclear what happened between monday and tuesday, but clearly there is a reason why they are so focused on the 25,000 acre reserve here behind me. and in the meantime, the fbi continues to ask the public for help. they're asking for any information locating brian laundrie and finding out what exactly happened to gabby petito. and they're saying, look, you can reach out to us anonymously. they want to know if anyone had contact with them. maybe they saw their vehicle between august 27th and 30th. >> and cnn spoke earlier with chris wicker, a former fbi assistant director for the criminal investigative division. and here's what he had to say about where the public tips can actually help the fbi in their search. >> whenever you open it up to the public like this, you're going to get -- you're going to go down rabbit holes. you're going to get extraneous information, people that want to be involved in some way. but you're going to get that nugget in there somewhere. and if you have enough manpower to search through it and corroborate the information that comes in, you know, it is a great force multiplier. i think the internet is a game changer here because there are quite a few internet sleuths out there that are able to do internet dark web and pretty broad internet searches that dredge up information that law enforcement may miss. so they're right to go out to the public in a case like this. i think they are getting leads and have gotten quite a few good leads out of it. >> and for more on this investigation, be sure to visit our website at cnn.com. well, the white house says president joe biden held productive and candid meetings with key democrats, including moderates and progressives. mr. biden is looking to unify party members as democratic divisions threaten to derail his economic agenda. cnn's ryan nobles has more from capitol hill. >> reporter: wednesday was a crucial day for the biden white house as the president inviting a number of lawmakers currently at odds over the path forward on the biden economic agenda to come to the white house and attempt to hash out some of their disagreements. the president meeting with chuck schumer and nancy pelosi, the democratic house leaders. then a group of moderate lawmakers, and then a group of progressive lawmakers. the goal here, to try and find a path forward that would allow them to not only pass the bipartisan infrastructure bill, that $1.2 trillion plan that would entail roads and bridges and other things, and at the same time pass a much larger $3.5 trillion human infrastructure plan that would serve as kind of an overhaul of the american federal social safety net, dealing with things like education, climate change, health care, and many other things. now, coming out of those meetings, lawmakers seemed optimistic that they did make some progress, but acknowledged that they had a long way to go. there are a lot of members of congress on the democratic side who are uncomfortable with spending as much as $3.5 trillion. so senator mark warner of virginia who is part of the moderate group said there was a robust discussion around that top line number. whether or not that number should come down a bit. now, on the progressive side, they've been insistent that monday is much too early to vote for that bipartisan infrastructure bill because if the house were to pass it, the president could ultimately sign it into law, and their concerned that would mean the reconciliation package won't be as strong of a focus of the moderate members of both the house and senate, and for some reason the entire situation could blow up. now, the house speaker nancy pelosi, after her meeting with president biden, insisted that they were on the right track. >> i will not be talking about that right now. we are on schedule. that's all i will say. >> thank you, ma'am. >> and we're calm, and everybody's good, and our work is almost done. so we're in good shape. >> reporter: important to point out there pelosi is saying they are on schedule which means she still plans to bring that bipartisan bill up for a vote on monday. now, pelosi has a history of not bringing anything into the floor that she does pren't think coul pass. the big question is what could happen between now and then on the broader $3.5 trillion plan that would make her feel comfortable and, more importantly, her progressive caucus members feel more comfortable they could vote yes. that is going to be her challenge over the next couple of days.

welcome back, everyone. we have new developments on the migrant crisis at the u.s./mexico border. about 5,000 migrants, mostly from haiti, remain under the del rio international bridge as they seek asylum. that's down from as many as 14,000 over the weekend. cnn's priscilla alvarez takes a look at the growing pressure on the biden administration to contain the crisis. >> reporter: the biden administration facing fresh criticism from democrats and republicans as they respond to the situation in del rio, texas, where thousands of migrants, primarily haitians, have amassed under an international bridge. the department of homeland security is getting ready to send as many as seven flights a day to haiti. they are also in touch with brazil and chile to possibly repatriate some of these haitians to those countries. these are malaysians who fled the 2010 earthquake and have lived in south america for several years. we have also learned that the department of homeland security is releasing some migrants into the united states with a notice to appear at an immigration office where they will then continue on with their removal proceedings. but all of this as they try to grapple with that situation on the ground in del rio, texas. we know from the homeland security secretary alejandro mayorkas that they anticipate clearing out that area between nine to ten days. priscilla alvarez, cnn. >> even with so many haitians being turned away, it seems thousands more could be headed to the border soon, as cnn's rosa flores reports. >> reporter: as thousands of migrants wait in a makeshift camp under the del rio international bridge to get processed by u.s. immigration authorities, a miles long steel barrier of texas state trooper vehicles has gone up. to deter the up to 30,000 haitians, cnn has been told could be heading towards the border. >> if you are targeting texas to come to, we're going to show up in force and shutdown the border. >> reporter: the camp beginning to dwindle in size. the fate of the migrants still there uncertain. some are returned to their home countries. others are allowed to stay. so he feels well he is able to stay. one by one, migrants under the bridge, many officials say are haitian, are loaded onto buses and transported to processing facilities. >> we do enforce our immigration laws. those are not only the laws of humanitarian relief, but the laws of accountability, for those who seek to enter illegally and do not have a claim for relief under law. >> reporter: some are expelled to haiti and other countries under a pandemic health rule. and nearly a thousand have been dropped off by border patrol at this nonprofit refuge pending immigration cases in the past three days according to the group's director. >> this is a tremendous amount, like nothing we've ever seen. >> reporter: that's where we met luis, a haitian who says he and his wife waited under the bridge for about a week. what did immigration tell you? he said immigration told him if he didn't appear in court he could get deported. his destination is new york. did anybody tell you why some haitians can stay and some haitians have to be deported babbl back to haiti? [ speaking foreign language ] he says that his understanding is that because he had an address, a family member he could contact in the united states, that he was allowed to stay. >> reporter: cnn has not been able to confirm luis's experience applies to everyone. the next stop for many of these migrants, a nearby gas station where vans and buses take them to cities across the nation. [ speaking foreign language ] >> he's going to miami. >> reporter: that's where we met peter who is from haiti, too. [ speaking foreign language ] >> reporter: as he says he's afraid of being deported to haiti, he has to run. his van has arrived. it's what life has been like for these migrants recently. a hurry up and wait into an uncertain future. the biden administration ramping up the deportation flights to seven a day. the destinations would not just include haiti, but also countries like brazil and chile. according to the administration, these are some of the transition countries where haitian nationals have been living for the past few years. at last check, the del rio mayor says that there are more than 5,000 migrants still waiting to be processed by u.s. immigration authorities. rosa flores, cnn, del rio, texas. and now to the other side of the border where cnn's matt rivers says some migrants are crossing back into mexico for supplies as conditions at the camp continue to deteriorate. >> reporter: well, very busy day here at the u.s./mexico border. we are just across the river there behind me from del rio, texas. that is where thousands and thousands of haitian migrants have been over the past week. and we saw many of them during the day today actually crossing the rio grande behind me, coming here into mexico. and we asked many of them why were they doing that, following this guideline that's strung across the river. they came to mexico to get supplies. they say the conditions of the encampment are such that if you come to mexico, it's easier to get food and water. we saw parents picking up diapers and clothes. that's what we've seen essentially all day long. they are trapped between the law enforcement between mexico and the u.s. if they choose to stay in the united states, some are being let into the u.s. after being processed by law enforcement. others are being deported to haiti. the exact same thing is happening on the mexican side. some are being let into mexico if they have the proper paperwork in terms of asylum claims. others will eventually be deported back to haiti, according to government officials. that is the situation. these haitian migrants have to choose which side to go to. we also saw some dramatic scenes earlier today. what happens here along the river is there are regularly scheduled dam releases, dams upstream where water is released and the water levels rise dramatically in this river behind me. we saw one man, including migrants are not aware of that, not used to that. we saw one man that you can see here with his daughter on his shoulders going across the river. came here to get her a meal. was going back to the encampment in the u.s. and they almost went under because of how strong the current was. three or four other migrants ho to jump in the water and help save not only the man, but the child that was on his shoulders. and then a little bit later on, we also saw someone try and swim ross. clearly not a good swimmer. and was actually swept down the stream. several other migrants jumped in after him. he was yelling, he was clearly panicking. and actually border patrol agents from the u.s. side threw him a line and he was actually able to grab onto and pull himself to safety. it's a dramatic scene here on the u.s. border. it's difficult times for the migrants as they have to decide where do they go from here. do they stay in mexico, do they stay in the u.s., do they take the corresponding risk from each side. matt rivers, cnn, mexico. and the fallout from the trump administration's harsh immigration policies still haven't been resolved. attorneys are still trying to reach the parents of 303 migrant children who were separated at the u.s./mexico border under trump's so-called zero tolerance policy. the biden administration has promised to help reunite these families. a court filing says so far, 50 children have been reunited with their parents in the united states. well, the washington, d.c., police department has been hit with a massive $100 million lawsuit by black female officers

14% from last week's daily average. but the death toll has surged to a six-month high. with more than 2,000 americans succumbing to the virus each day on average, and that is despite most adults having ample access to vaccines for months now. and yet less than 55%, although pretty much nearly 55% are fully vaccinated. meanwhile, the food and drug administration has now approved a pfizer booster shot on an emergency use basis for people over 65 and those at high risk of severe disease. cdc advisers will discuss boosters later today and decide what to recommend based on this new fda decision, but as cnn's nick watt reports, many are still refusing their first shot. >> reporter: in north carolina, dozens of unc health employees have resigned rather than get a covid-19 vaccine. >> it absolutely is about our freedom. you know, we should have the freedom to choose. >> reporter: meantime, in the ten least vaccinated states, there they are in red. the covid-19 death rate was four times higher this past week than in these states. the ten most vaccinated. wyoming just activated the national guard to help an overcrowded hospitals. in north dakota the school board members facing a recall after winning the push for masks in schools. she is a pediatrician. >> masks are one way of a layered approach to help us keep kids in school. and even if it's unpopular, i'm always going to try to advocate what's best for children. >> reporter: the mask wore update in texas, a couple with an immunocompromised kid at home went out for dinner, and -- >> she came up and basically said, you are going to need to pull your mask down, take it off, because this is a political situation. but the owner here doesn't believe in masks and, you know, there is a strict no-mask policy here. >> reporter: so they had to leave. >> i spent my money on this business. i put my blood, sweat and tears in this business. i don't want any masks in here. >> reporter: in florida the no mask wearing surgeon jen was the man for the job. he wrote that mask wearing has had at best a moderate affect on transmission. not true. studies show the effect is significant. meantime, the nation's average daily death toll just topped 2,000 lives lost a day. hasn't been that high in more than six months. >> we are going to be living because of some people's hesitancy to take vaccines at a plateau, hundreds of people, maybe even a thousand dying on a daily basis for the foreseeable future. and by that i mean a year or two. >> reporter: and late wednesday the fda in the united states has granted emergency use authorization for a third booster dose of the pfizer vaccine for people 65 and up. also people at risk for severe disease and people who have jobs that put them at risk of infection. nick watt, cnn, los angeles. >> and third doses are already approved for the immunocompromised. more than 2 million americans have already received them. but a former fda commissioner thinks the eligible age group will be expanded. dr. scott gottlieb, the author of the new book "uncontrolled spread" had this to say. >> the advisory committee cdc is going to meet and interpret the fda authorization, and we'll see what kind of recommendations they make around that because that could be quite broad. it could include a lot of people who are at high risk from a bad outcome from covid because they're more likely to come into contact with the disease, that they're working in occupations where they're put at risk of contracting the illness as well. so cdc is going to get an opportunity to opine on it. i suspect what will happen is we'll continue to collect data on this cohort 65 and over and other people made eligible. they may walk down the authorization to younger cohorts depending on what they learn from the data set in the united states. there are new signs of progress around the globe. the world health organization says global covid-19 cases and deaths have continued to decline over the past week. the number of deaths went down 7% compared to the week before. the eastern mediterranean and southeast asia saw a substantial decrease in both coronavirus deaths and infections. well, the washington, d.c., police force is under fire for its alleged mistreatment of black female officers. a group of current and former officers announced they are suing the department for $100 million. cnn's suzanne malveaux has our report. >> reporter: i spoke with several of those police officers involved in the class action lawsuit against their own department, and some are still on the force. they described feeling afraid, anxious, depressed, but also very much resolved to change what they describe as a toxic culture within the metropolitan police department here in washington, d.c. that is allegedly particularly abusive toward black female officers. the group of ten said they experienced racial and sexual mistreatment, a hostile work environment, bullying and retaliation. it offers what they call an unprecedented look inside the mpd's blue wall of silence which involves civil rights violations and serious misconduct. the class action lawsuit actually represents more than 700 black female officers who are or were employed by the department from ten years ago to the present. now, some of the most egregious allegations in the suit include a male fellow officer showing a plaintiff a picture of a gun that he said was going -- he was going to use to assassinate former first lady michelle obama, and another male officer urinating in the police van in the presence of a female officer. >> you see how a black female or black chief of police, if they don't listen to the voices of women, then the women are going to get ignored. and it's time that we stop ignoring women. i think that was the point of the me too movement, but somehow the me too movement often excluded, did not include "the voice"s of black women. so this case is not just about retaliation. it's not just about bullying. it's not just about all of the discrimination we talk about. it's about the fundamental disbelief of women, and the devaluing of their voices. >> it made me feel totally disrespected. i worked so hard to keep my -- to be a strong black woman, and it made me feel like i was nothing. i felt like i was just nothing to him. the other young man had enough respect for me to get out of the car and go urinate in the woods. you had no respect for me, even though you didn't pull out your penis directly in front of me, you were behind me, directly behind me, and you still did that. >> reporter: the overall common complaint is the overall practice of mpd covering up women's complaints and allegedly punishing them for speaking out. a statement from the department reads, the metropolitan police department is committed to treating all members fairly and equitably throughout our organization. we take these allegations seriously, and we will be reviewing them thoroughly and responding accordingly. now, the lawsuit is calling for someone independent to be appointed to overhaul the mpd's personnel practices, get the cooperation of d.c. mayor muriel bowser, and to establish a $100 million fund to address the harm done to these women. suzanne malveaux, cnn, in washington. while we follow developments in the search for gabby petito's fiancee, we are also keeping an eye on another case. the murder of a couple in the mountains outside moab, utah. the bodies were found five weeks ago, but no suspect has been named. schulte's father

afghanistan briefing with the biden administration on wednesday. three sources say both republicans and democrats were frustrated after officials with the state department, the pentagon, homeland security, and national security failed to answer even basic questions. lawmakers say what's still unclear is how many americans remain in afghanistan who want to get out. meanwhile, the u.n. is releasing emergency funds to try to prevent the collapse of afghanistan's health care system. jumanna caratachea is in istanbul following this story. what more are you learning about this? >> reporter: rosemary, as you know, long before this current crisis, afghanistan was considered one of the worst humanitarian crises in the world, and this current situation, this current crisis has exacerbated the dire humanitarian needs in this country, a country that is so reliant on international aid. you know, as the international community donors around the world are trying to figure out how they're going to be dealing with this new political reality on the ground, an afghanistan that is under the control of the taliban, the withholding of aid right now is having a devastating impact on the country's basic services. for example, you know, we saw yesterday an urgent dire warning coming from the world health organization, saying that the country's health care system right now is on the verge of total collapse. and that unless urgent action is taken, the country is facing an imminent humanitarian catastrophe. and the reason for this, rosemary, is they're saying the largest health care project in the country, the project that is mostly funded by the world bank and usaid and others. and as they are withholding this aid, what they have seen is that thousands of medical facilities have had to either reduce their operations or shutdown altogether. and about 17% only of sahetmundi's health care facilities are up and running right now. this is because they have run out of medical supplies, because they can't pay their staff. and this is having a rippling effect across the country on basic health care services as well as the emergency response. and when we talk about emergency response, rosemary, the world health organization says that includes the polio campaign. afghanistan is one of two countries in the world where polio remains endim emic. they are shutting down as covid cases are continuing to rise. the campaign vaccination, they had to stop their 1.8 million doses that are sitting there that they have not been able to administer since august. and only about 5% of the country's population has been vaccinated. so a dire warning coming from the world health organization, which seems to have prompted this release of 45 million u.s. dollars announced by the united nations under secretary-general for humanitarian affairs. and this, rosemary, is really just to stop and prevent a total collapse of the health care system. nowhere near enough to begin to address the dire humanitarian needs in that country. >> it is just shocking. you talk of polio. that's exactly why people need to get their vaccines, for all of these sorts of diseases, for covid, for polio. so we can eliminate these sorts of diseases across the globe. many thanks for bringing us up to date on that dire situation in afghanistan. prime minister boris johnson is urging the world to grow up when it comes to climate change. in a speech at the u.n. general assembly, he slammed what he called the world's infantile approach, and he's asking countries to speed up their commitments to fight the problem. nina dos santos explains. >> reporter: six weeks before he is set to host a major climate change summit on his own soil here in the uk, boris johnson, the british prime minister, used his united nations assembly address in new york to rally the cause for more urgent action on climate change. with more blunt language you can hear here. >> my friends, the adolescence of humanity is coming to an end, and must come to an end. we are approaching that critical turning point. in less than two months, just over 40 days, when we must show that we are capable of learning and maturing and finally taking responsibility for the destruction we are inflicting, not just upon our planet, but upon ourselves. >> reporter: in johnson's own inimitable style, he said the world was essentially behaving at the moment as a bunch of reckless teenagers not realizing the damage they're causing. it's time for the world to grow up and take responsibility and listen to the scientists. the backdrop to all of this is there have been concerns about the diplomatic effort underway ahead of cop-26 which is set to take place in glasgow in scotland in just six weeks' time is falling perilously behind. and there have also been various sets of data that show that when it comes to the targets of climate change, namely limiting global warming to around 1.5% of pre-industrialized levels, that is also far off the mark at the moment. nina dos santos, cnn in london. autumn is off to a rough start, but tens of millions of americans, we are looking at heavy rain and possible flooding in the east with a new tropical threat brewing in the atlantic. derek van dam is here with more. is it the new normal? what are you seeing? >> yeah, what we're seeing is hefty rainfall totals across the great lakes all the way to the east coast today. take a look at this past 36 hours, we've seen some significant amount of precipitation across the state of michigan, particularly around the detroit metro region. check out the shades of orange and yellow. that's indicating anywhere between 2 to 4 inches, even locally higher amounts, though. that's within the past day and a half. but guess what, that rain has to move somewhere and it's generally going to move eastward. in fact, you'll see that with this cold front here that's brought in some cooler weather behind it. but not without, of course, causing some havoc. flash flood threat for about 40 million americans. so this covers many of the major metropolitans from new york to boston, as well as philadelphia, and the nation's capital. they did allow the flash flood watch in detroit to expire as only a few 10th of an inch of rainfall dissipated for you. look at the line of storms that are going to greet you as you head out the door. for the major east coast cities, i-95 corridor, that will be a slow go today with rain moving through, 2 to 4 inches of rain not out of the way throughout the area, potentially leading to localized urban flooding. plenty of wind associated with the passage of this front as well. expect gusts anywhere from 15 to 35 miles per hour. that cold front will bring big changes to the air. it's going to remove that humidity and bring in much welcomed fall-like weather across the eastern seaboard. good news and it's going to stick with us throughout the course of the weekend. the tropics, we have peter and rose still churning across the central atlantic. now all eyes are focused on tropical depression, 18 newly formed. this is going to move in a generally western direction and has the potential to impact land in the next seven days. rosemary? >> thanks so much, derek, appreciate it. confirming what parents knew, instagram is toxic for teen girls. facebook now under fire for what its own investigation

company knew that instagram poses serious dangers to mental health in teenage girls. cnn's sunland sofarti explains. >> reporter: taylor has grown up on instagram. first creating her account in the 6th grade. >> i was in a very, like sad kind of like lonely place. >> reporter: her darkest moments of self-doubt over the last decade, she says, have all been triggered by what she sees on her feed. >> i felt like very isolated in my friend groups. that was just totally perpetuated by instagram. i would see all my friends going and doing these really fun excursions with their other fun groups. i was wondering why i wasn't doing any of that. >> reporter: those harmful feelings are exactly what instagram already knows. according to company documents obtained by "the wall street journal," facebook, the parent company of instagram, spent the last three years trying to understand just how toxic instagram is to young people. that internal research is damning, saying that comparisons on instagram can change how young women view and describe themselves, their researchers wrote. teens blame instagram in the rate. among teens who reported suicidal thoughts, 13% of british users and 6% of american users traced their desire to kill themselves to instagram. >> i would say 99% of the time the patients i meet with are reporting looking at idealized images and feeling horribly about themselves and using those images as a basis of comparison that really results in feeling like a failure often. >> reporter: in the wake of these internal findings, facebook is pushing back, calling the reporting deliberate, mischaracterizations, and conferred egregiously false motives to facebook's leadership and employees. adding that they believe "the wall street journal" report cherry-picked selective quotes from individual pieces of leaked material in a way that presents complex and nuanced issues as if there is ever one right answer. instagram says it is looking at new ways to discourage users to focus on their physical appearance and making it a positive space for all. but lawmakers on capitol hill say that is insufficient. >> after this revelation, mark zuckerberg has to come down to capitol hill. he has to give answers. >> reporter: and have demanded facebook release their findings. >> he has to explain why he knew about the dangers, and yet continued his business practice. >> reporter: in the past facebook has taken pains to downplay the negative impact on teens. >> mr. zuckerberg, yes or no, do you agree too much time in front of screens passively consuming content is harmful to children's mental health? >> i don't think that the research is conclusive on that. >> reporter: an assessment that lawmakers aren't buying. >> we all knew that that was a hollow talking point back then when he said it. but obviously this internal research shows that he knew or at least he should have known that it was the exact opposite. >> reporter: and lawmakers have sent mark zuckerberg a letter with a series of questions, including asking for a copy of that research. they have given him three weeks to respond. and if he doesn't, they expect him to be called back to capitol hill to testify. sunland serfaty, cnn, washington. excitement is building over a fan-favorite event in golf. here's don riddell with a minute in sports. don. >> hey, rosemary, golf's ryder cup
