total u.s. population is fully vaccinated. as we wait for younger kids to become eligible for covid vaccinations in the u.s., many parents are wondering how and when that might happen. cnn has more on the planning process. >> reporter: the roll us of vaccines for ages 5 to 11 is similar to what we saw for older kids. i want seems like the potential sites for administering vaccines to younger kids will be at some pediatrician's' offices and local pharmacy, just like the previous roll out with adolescents. another potential site could be schools which we haven't really seen before. for instance in virginia governor ralph northam said schools could be involved. >> easiest and most equitable way to deliver the covid vaccine is a school, to have the health department come in and give the shots. so, our teams are working with school divisions and superintendents to do that wherever possible. >> of course, all of this depends on the fda authorizing the covid-19 vaccine for younger ages and the cdc recommending it. but in the meantime there are steps parents can take to prepare. you can call your pediatrician's office just to see if they plan to off terrify vaccine to ages 5 to 11 once it's available and if they don't plan to then at least you know now you have to make an appointment at either a pharmacy or local vaccine clinic instead. back to you. thank you so much for that. joining me right now discuss is a doctor, a pediatrician and a medical director of the los angeles unified school district which is the nation's second largest school district. doctor, so good to see you. how is your school district preparing for a possible vaccine roll out? would it be like virginia consideration of inoculations at school? >> los angeles unified school district has been the at the foreground of this for a very long time. we already had vaccines for students age 12 and above because we recently did pass a mandate for vaccinations for students age 12 and above in our school district. and so we have been providing school based clinics that have been providing the vaccine. in addition we have mobile units going to all our middle and high schools providing vaccinations for our students. and we've been work our public health department to provide vaccinations throughout our district. we've been on the forefront of this and already been doing this. >> what would be the impact if, indeed, a vaccine is made available for kids between 5 and 11? >> so, we are already prepared to off terrify vaccine for ages 5 to 11 as we already have this large vaccine roll out plan happening. but we are also, you know, waiting to see what the data shows from the fda and also wanting to talk to our university partners and public health department. >> okay. a recent poll from the kaiser family foundation found that just over a third of parents with 5 to 11-year-old kids will vaccinate their kids as soon as they are eligible. 32% say they will wait and see how the vaccine is working while 24% say they definitely will not vaccinate their children. so how do those numbers hit you? what are your thoughts and concerns >> as a parent of two young children myself who are too young to be vaccinated i can't wait to get my children vaccinated. you know, now we have this opportunity. we have 28 million americans in the age range of 5 to 11-year-olds who would be eligible to get the vaccine and so we have a greater opportunity to stop the transmission of the virus so that eventually we can get to a place where in our schools we're not testing all the time. we can get to normalcy for our schools and our students. >> yeah. i too, i can't wait. i got two kids who are under 11. i can't wait for them to be vaccinated. i had such a sense of relief when my 16-year-old was able and eligible and so i feel good that he's vaccinated. i can't wait to have the same feeling for my younger kids. but there's still a great reluctancy, what if anything will you say to those parents. how will you convey to them the kind of optimism that you share? how do you impose that on them? >> so i understand those questions. i've been asked that a lot and i want to emphasize that the process that the fda uses to release an emergency use authorization for vaccines is actually quite extensive and safe and when they release the vaccine for the different age ranges what they have determined is that the benefits of the vaccine. outweigh the risks and that there is enough compelling evidence to the effectiveness of that vaccine for that age range and in those children and so there are multiple safety checks including the advisory committee on immunization practices who will also look at the data and advise the cdc on how to proceed and so there's multiple safety checks and i believe in the safety and eifficacy of the covid-19 process. >> a new study suggests kids always had similar risk for coronavirus as adults but more likely to be asymptomatic. this count terrifies false narrative the from early on that suggested kids were not affected by the virus. i feel we're light years away from that. there's still that message that some folks are hanging on. what's your message to those parents who still believe that? >> so, according to the american academy of pediatrics almost 6 million children have been diagnosed with covid-19. with 850,000 cases in the last four weeks. now this is due to the delta variant, not the severate of the delta variant but the increase of the transmissibility of the delta variant. out of the 500 americans under age 18 who have died from the virus, 125 of them have been age 5 to 11 years of age and we have to understand that covid-19 is now becoming a vaccine preventable disease. and for any parent to lose a child to a vaccine preventable disease is a tragedy. >> yeah. that's devastating. i want you to listen to this video of protesters now in california shouting at parents for kids having to wear masks. >> i mean this is what is happening and then you see, you know, both sides of the argument there. there are children in attendance. so, you know, how heartbreaking is this for you to see? >> this is absolutely heartbreaking and speaks to the amount of misinformation that there is out there. masking protects not only you but others around you. and what this pandemic has shown me is how interconnected we all are and when we wear masks we're doing it for ourselves and our communities and to prevent the transmission of this virus even further from new mutations to arise and we can ultimately get to a sense of normalcy. one of the mitigation efforts we use. children have been remarkably resilient to masking. both of my children age 4 and 7 have been wearing masks since the beginning of this pandemic and now it's second nature the home. >> right. you don't have to ask. once you get into a rhythm of thing. they understand the benefits as well. all right, doctor, thank you so much. appreciate it. >> thank you for having me. >> absolutely. come back. still ahead, subpoena showdown. and a fight over executive privilege. we'll bring you the latest as the january 6th committee works to uncover truth. as the search for brian laundrie enters a fourth week i'll talk to a criminologyist about the puzzling timeline and what we know after gaby petito went missing. but with our new multi-cloud experience, you have the flexibility you need to unveil them to the world. ♪ (vo) unconventional thinking means we see things differently, so you can focus on what matters most. that's how we've become the leader in 5g. #1 in customer satisfaction. and a partner who includes 5g in every plan, so you get it all. i've always dreamed of seeing the world. but i'm not chasing my dream anymore. i made a financial plan to live it every day. ♪ ♪ find a northwestern mutual advisor at nm.com i strip on public transit. i strip with the guys. i strip all by myself. breathe right strips open your nose for relief you can feel right away, helping you take in air more easily, day or night. ♪ ♪ i can turn anyone into a beach bum. i bring families together for a living. i make memories for people i don't know yet. i know this view is too good not to be shared. i am a vrbo host. ♪ ♪ we're following new developments on the capitol riot investigation. a source tells cnn that dan scavino a top aide to information president trump has now been served with a subpoena. scavino is one of four former trump aides that the january 6th select committee wants to appear at a deposition next week and this comes amaid growing showdown over executive privilege. trump is trying to assert executive privilege to keep documents and other information zp from the select committee. days after the u.s. senate narrowly averted the u.s. government defaulting on its bills, mitch mcconnell is telling democrats not ask minorities help on raising the debt ceiling again come december. we go wilmington, delaware where the president is spending the weekend. let's beginning with daniela diaz. the next limit of the debt level fight. mcconnell sending this letter to biden. now what? >> we wait and see what happens, fred. this week was really busy especially on the senate side as the democrats navigated trying to figure out how they were going to pass a suspension or raise the debt ceiling before this october 18th deadline that treasury secretary jessica yellin warned would be the day that the nation would default on its debt. then you have dramatic effect on the economy in this country which is why the senate was racing to address this after the house pass ad bill raising the debt ceiling. so, look, mitch mcconnell warned weeks ago that democrats would have to go at this alone, that republicans would not help democrats. however, he did cut a deal with shum they are week which is why they suspend the debt ceiling until early december but he did send a letter to biden last night where he had very strong words for democrats saying he's not going this again. he won't help them again. take a listen to what he wrote. senator schumer marched the nation to the door step of disaster. embarrassingly it got to the point where senators on both sides were pleading for leadership to fill the void and protect our citizens. i stepped up. now the problem here is democrats are now going to have to scramble to figure out how they will address the debt ceiling in early december so the nation doesn't default on its debt and have to do this alone. they are looking at many ways to do this, probably through a complicated process like budget reconciliation but they have to put a number and then own that which republicans want. democrats were hoping to avoid that. also democrats argue that this has been a bipartisan issue since 2011 which is why they wanted republicans to help them with this. so bottom line here is lot of tension, lots of arguments here within republicans and democrats as now they are going to have to work these next two months to figure out how they will address this. >> tension to say the least. thank you so much. let's go to wilmington. what is the president saying about this disappointing new jobs report? >> reporter: well, fred, biden is trying to put a positive spin on that weaker than expected jobs report for the second month in a row. only 194,000 jobs were added last month. the president argued that this was due to the delta variant. the survey was taken around mid-september when cases were reaching a peak but now we have seen a drop in many covid-19 cases and hospitalizations. the president also was trying point to some bright spots in these numbers. he argued the unemployment rate fell from 5.2% to 4.8%. that may be due to fact thousands of people threat labor force. the president was pointing to a jump in wages as well as over all job growth since he took office amid this pandemic. the president argued that there is steady progress being made even if it's not as fast as people would like. take a listen. >> right now, events in washington as you know are noisy. turn announce and every conversation is a confrontation. every disagreement is a crisis. when you take a step back and look what's happening we're make real progress. be maybe it doesn't seem fast enough. i would like to see it faster. we'll make it faster. maybe it doesn't appear dramatic enough. >> reporter: now this is just one period of the challenging economic puzzle that the president is trying address. hisened is still stalled up on capitol hill. and that looming fight over the debt limit coming up in less than eight weeks. all of these challenges, things that the president will need address as he's hoping to boost the economy going forward. >> a lot on the table. thank you so much, ladies. the price of filling up your gas tank has reached a seven year high. we have more on the reasons behind the rising prices. >> reporter: pain at the pump is real for many americans right now. gasoline prices are above $3.27 a gallon nationally the highest level since 2014. drivers in california, colorado and illinois are seeing even higher prices. high gas prices hit low-income americans the hardest and threaten to intensify america's biggest the inflation scare in more than a dozen years. this is a political problem for biden too. even though the blame from republicans is largely misplaced. voters do not like high gas prices, and fair or not they tend to blame whoever is in the white house. even though electric vehicle sales are booming they still represent a small piece of the pie. unfortunately, industry source tell me there isn't really much biden can do about energy sticker shock. plan a was to get opec and its allies to stop production. that's failed. plan b could be to tap america's emergency stockpile of oil. energy secretary suggested that could be in the cards. but the energy department later walked that back and told me there is no immediate plans to tap the spr. there's a lot of skepticism releasing barrels would work because of the size of the supply short fall. one analyst told me this would be like bringing a squirt gun to a fight. won't make a dent. another to ban oil exports. energy secretary seemed to suggest that was a possibility but the energy department walked that back too. banning oil exports could make prices go higher. oil is a globally traded commodity and limiting u.s. barrels would make oil prices go higher. that brings us back to points a convince go peck to aggressively add to supply. of course energy diplomacy would seemingly run counter to another top priority this fall, climate diplomacy. biden is meeting with world leaders in glasgow later this month at a summit of weaning economies off of fossil fuels. no one said this energy transition would be easy. >> thank you so much for that. coming up, the manhunt for brian laundrie is intensifying. the constant updates to the timeline much his disappearance left authorities confused. the latest on the investigation straight ahead. you could fret about that email you just sent. ...with a typo. aaaand most of the info is totally outdated. orrrr... you could use slack. and edit your message after it's sent.

do you feel like investigators are period pleksed or is it just publicly they are not revealing everything they know about his potential whereabouts? >> listen, i think if we knew more than they are saying they would have -- they need the public to help them solve this. if they had any pings off his sfoerngs legitimate sightings of him in a particular area they would share that with us in the hopes that the public could solve this. the fact that after a move searching the reserve or three weeks of searching the reserve they haven't found anything, nothing at all. >> amazing. >> they are abandoning hope the at the reserve and you're left wondering if they have anything else. >> what's the psychology behind brian laundrie's father joining in on the search when it doesn't sound like he was very coopcoop cooperative at the beginning. >> it's another fin on the red herring. brian's father want to legitimatize the story and a story he contrived with brian he was going lot of stuff doesn't make sense. mustang there allegedly abandoned. like they were putting a time date stamp to infer he was there. i personally don't believe that he was there ever. but, father going to the reserve and showing them possible camp sites where he may have been in the past. i think the police know that he's not there but they wanted to observe chris laundrie, and watch his behavior, try to figure out whether or not he is being truthful. and then gauge from there if they could actually get him to trust them with what he does know because there's one thing for sure. the laundrie family knows a lot more than they are telling the police. >> right. so you said you don't believe that laundrie has been at that reserve at all. you believe the family in some way has been helping laundrie buy time to make some other escape. where do you suppose -- which direction might he go? if not where the family says the reserve. do you think he's still in the country? >> i don't believe he's in the united states at this point. to be fair i don't know if the laundrie family is actually aiding and abetting or just buying a story he told them hook, line and sinker. let's assume that they are unknowingly helping brian at this point. but what is today? the 9th. we haven't seen him for almost four weeks. it's the camping trip that they took north that has me most interested. >> once he came back on september 1 in the van that belonged to gaby petito. this camping trip what do you think happened? >> we know he picked up the phone on september 4th. from the 6th to 8th he went to the desoto campground north about an hour's drive away. that campground is all water. that could have been a dry run or the last time that we saw brian that the family saw brian. there aren't any confirmed sightings of him after the 4th. be so easy for a boat to pick him up at the desoto campground and take him to the caribbean, maybe cuba that doesn't have an extradition treaty. i hope the parents will cooperate with the police. >> it sound like you believe it's inconceivable the family would not have had a discussion with brian laundrie. how is gaby? where is she? how come you came back without her? >> obviously there were discussions. the question is whether or not brian told them the truth or lied the home and if he tlied the home is the family engaging in what i have dubbed a pall of denial a willing suspension of disbelieve. a level of denial so far to this side that they actually almost self-brainwash and believe these lies even though they are irrational and illegaogical. if they kwooptd the police more i think we would have a good chance of figure out where brian laundrie is. >> right. casey jordan we may not have more answer about where he is but what you've done you helped reveal exactly what investigators are thinking, questions they are asking and directions in which they are going in order to find brian laundrie. thank you so much. >> lals great to be here, fred. appreciate it. still ahead thousands of gallons ever crude oil poured into the pacific ocean last week but now investigators think the cause of the leak may have actually happened a year ago. details straight ahead. hey google. ♪ ♪ ♪ ♪ ♪ ♪ listerine® cleans virtually 100%. helping to prevent gum disease and bad breath. never settle for 25%. always go for 100. bring out the bold™ going to tell you about exciting medicare advantage plans that can provide broad coverage, and still may save you money on monthly premiums and prescription drugs. with original medicare, you're covered for hospital stays and doctor office visits. but you have to meet a deductible for each, and then you're still responsible for 20% of the cost. next, let's look at a medicare supplement plan. as you can see, they cover the same things as original medicare, and they also cover your medicare deductibles and co-insurance. but, they often have higher monthly premiums and no prescription drug coverage. now, let's take a look at humana's medicare advantage plans. with a humana medicare advantage plan, hospital stays, doctor office visits and your original medicare deductibles are covered. and of course, most humana medicare advantage plans include prescription drug coverage. in fact, in 2020 humana medicare advantage prescription drug plan members saved an estimated $8,400 on average on their prescription costs. most humana medicare advantage plans include a silversneakers fitness program at no extra cost. dental, vision and hearing coverage is included with most humana medicare advantage plans and, you get telehealth coverage with a $0 copay. you get all this for as low as a $0 monthly plan premium in many areas. and your doctor and hospital may already be a part of humana's large network. if you want the facts, call right now for the free decision guide from humana. there is no obligation, so call the number on your screen right now to see if your doctor is in our network, to find out if you can save on your prescriptions, and to get our free decision guide. humana, a more human way to healthcare. one week later and oil spill off southern california coast near huntington beach is still spreading. a crack opinion pipeline that caused as much as 10,30,000 gallons to spill into ocean may have happened several months to a year ago. balls of tar started to wash up on the beaches. san diego. to the north another environmental crisis. dozens of california's giant sequoia trees have burned. the kmp complex fire scorched 85,000 acres destroying 74 of the treasured trees. four firefighters were hurt as one of those trees was falling. here to help us work through all of this, a professor who is a climate scientist and the director for the global change program at georgia tech. professor, so good to see you. so, we're all witnessing now the impacts of climate change every day, wildfires burning out west. more frequent and more powerful hurricanes and storms. i want seems the fallout from the use of fossil fuels may be largely to blame. so have we reached the point of no return or are we too late to turn the tide? >> no. not at all. but first we really have to recognize the vast untold damages of our continued dependence on fossil fuels not just this horrific oil spill or headlines that we've all had to witness as well but obviously all of the decades of communities that have suffered at the hands of contaminated water, contaminated air, and really, you know, health impacts for decades. it's not too late. that's the good news here is we still have time and this year is a very important year in thinking about how we can enact the deep and sustained cuts to fossil fuel emissions that will keep it to a minimum and cool in the latter part of this century snoofrpry day is vital to promote some change. u.n. climate change conference begins in just a few weeks. biden will be there. what kind of policy do you want to see come from this conference to reflect the real urgency, the global urgency? >> well, the new u.n. report on climate change very clear. in order to keep warming to a bare minimum this century, most ambitious target of 1.3 celsius, countries have to come together for net zero emissions by mid-century. but countries need to think about what kind of near term actions need october. we need to begin those reductions today. the other thing we're looking at is whether the biden administration can move forward. the most significant climate action in decades here in the united states, and bring that to the table this fall at the climate new yor climate negotiations. >> there's a number of provisions in the package being negotiated in washington right now. how critical it is right now for countries to start taking this climate threat seriously with real impact beginning with the u.s. led policies? >> yeah. well there are a number of provisions in these bills making their way through this tortured process in congress both to reduce emissions within our borders as well as to help communities gird themselves against what we know will be accelerating climate impacts over the next two decades until we can reverse this. the tune of these bills is in the hundreds of billions of dollars total but when we think about this bill we have to think about the size of what we're facing with climate change impacts. the national oceanic and atmospheric administration just yesterday releasing a report that hurricane ida, $60 billion of damages to our economy. this year already $100 billion of damages from weather and climate extremes. really have to compare apples to apples in terms of what this might cost us to get going in a serious way and what the continued damages will be year-on-year on year if we don't get serious about this. >> not just the immediate impact of extreme weather event that can have untold circumstances. one climate professor put it like this. i don't think there's a misunderstanding that all communities are think it the same but i do think when the dust clears not enough attention is given to the post-disaster trauma that exists after the headlines are gone. so in your view is enough being done particularly to address the long term impacts? >> no. unfortunately we're not prepared to weather these in an emergency sense day-to-day as they occur in real-time. we're not prepared to help communities come back from these kind of damages in the short term. we certainly aren't thinking about the longer term consequences. we can talk about hurricane harvey and studies that have come out and showed the intergenerational poverty and loss that's written into communities in texas from that event alone. we know that's only one of several dozen that we put at the top of our heads in terms of devastating environmental impacts. >> thank you so much for joining us. >> thanks for having me. >> a volcano in the canary islands is causing a major disaster. lava is spewing into the spanish town of la palma burning down homes in its path. more than 1,000 have been destroyed the insurance the volcano first erupted last month. the airport even had to shut down this week due to volcanic ash. cloud and thankfully thousands of people had already evacuated the island. holiday travel could be back in full swing this year, but as most of the major airlines employ vaccine mandates will they be ready for the travel surge?
