i'm john avlon with kaitlan collins. and we begin with the cdc cutting the recommended isolation period for many infected americans in half. the agency now reducing the number of days from 10 to 5 if you are asymptomatic. the cdc also is now recommending the same amount of time for vaccinated people to quarantine if they are exposed to the virus with no quarantine at all if you are boost. tr dr. anthony fauci says it is part of an effort to get people back to work faster amid major concerns about staffing shortages at hospitals, airlines and businesses because of the omicron surge. president biden is now grappling with the failure that could have been foreseen as the omicron wave has exposed shortages in the u.s. and access to testing. many frustrated americans are now waiting in long lines for tests if they can get them at all. speaking to governors on monday, the president conceded that steps he took to scale up testing capacity weren't enough to meet the demand. >> we went from no over the counter oig tests in january, 1 million in november and almost 200 million in december. but it is not enough. it is clearly not enough. if i had -- we had known, we would have gone harder quicker if we could have. we have to do more. we have to do better. and we will. >> the president has pledged to distribute 500 million test kits beginning in january, but some health experts say that will be too late for this week's holiday crunch. let's get to leyla santiago in miami where some people were waiting for more than two hours yesterday. >> reporter: yeah, when we arrived this morning, there were still those very, very long lines wrapped around this park, one of the busiest testing sites in south florida. we talked to one woman who told us that she arrived at 3:00 in the morning, she waited three hours to get that test. the health group that runs this testing site told us that they were expecting an increase in demand because of omicron, because of the holiday season, but what they are seeing right now is unprecedented. so much so that they are actually opening four to five new sites in miami-dade county to try to meet that demand. we've been talking to people in these lines, listen to what they told us. >> it is way more chaotic now. everybody is freaking out. but that is the same thing that happened right before the first time, you know, like everybody is like going everywhere about it. >> and there is a spot right by my house where i would go, it would take less than five minutes. he would just walk there and that is it. and now the line extends into like the next street. it is crazy. >> reporter: so that is kind of a compare and contrast of how things have changed in a matter of weeks, in a matter of days really. i should point out that this site is not just a testing site, they also have vaccination here. and we are clearly seeing much more activity when it comes to testing over vaccination. and these are on-site tests. when it comes to the take-home tests, miami-dade distributed more than 150,000 in pinublic libraries over a two day period and have run out and are asking more. >> yeah, people are desperate to get their hands on those take-home tests. thank you. and now let's bring in chief of infectious diseases at john hopkins all-children's hospital in st. petersburg, florida. dr. massena, thank you for joining us. what do you think of the new cdc guidance for folks with asymptomatic infections and those fully vaccinated and exposed to covid? a major change. >> yeah, definitely. i think that probably a lot of people were surprised about that. i do think that though the cdc is very carefully looking at the science behind this pandemic in that that the truth is that we're dealing with different markers than we were before and we're looking at the incubation period of this may be shorter. and adjusting the recommendations accordingly. the other issue too is of course as was mentioned in the previous segment, this is a very contagious virus and if we are going to be faced with some fairly significant staffing shortages if we don't respond to that, and so i think for those reasons, that was the reason the cdc changed the guidelines. >> yeah, we know dr. fauci has said that that was really a driving factor in this process and why the cdc made these changes. but we are seeing cases rise exponentially across the united states and some health experts have said that that will continue for weeks, maybe peaking maybe not until mid-february. so i'm wondering what you are seeing at johns hop ken ss hopk all-children's hospital. >> we're seeing a definite increase in cases over the last few weeks. i would say that we have not seen the worst of it yet however. remember that at a children's hospital we're obviously dealing with that population, and the fact of the matter is that children aren't in school right now because it is still the holiday break. i think that what we're going to see is once children go back to school within a week or two of schools opening is when we'll see our highest numbers. >> and that is significant. i've got two young kids and is that one of the questions that parents talk about all the time. what about going back to school. you're saying that when kids go back to school, you expect a further increase in childhood cases and hospitalizations which are already above what we've seen previously, is that right? >> yeah, i mean even if you look at respiratory infections every winter even pre-covid, we always saw a lot of activity within the week or two of schools starting up again after the break. so we expect to see that again. as far as how high or what we'll see in terms of kids needing to be hospitalized versus kids that are well enough to go home, that remains to be seen. we hope that even if we do see those big numbers that the majority of patients will be well enough to go home. but we know that when it is this widespread, we know that it will increase hospitalizations and we're getting ready for that. >> and we've seen that in some other places where the children who are being hospitalized, it is continuing to rise. good news is some health experts have said that they have not been really severe cases. according to the cdc and department of health and human services, last week there was an average of 262 kids hospitalized per day, a 35% increase since the week before that, but still below the numbers from late august and early september. and so of course children under 5 are the last group ineligible for vaccines. so what is your advice for parents who are watching this and want to know the best way to protect their kids right now? >> yeah, i would say that, you know, certainly if your child is age 5 and up, it is vaccination, vaccination, vaccination. we can do better in these age groups. not a ton of kids who are eligible for the vaccine have had it. and so that is huge. for the kids that are under 5, you really only have masking, distancing and trying to keep those children protected by vaccinating everyone else in the family that is old enough to be vaccinated. and the same measures as we have been, you know, describing even earlier in the pandemic. those pieces of advice still apply. >> vaccinated, vaccinated, vaccinated, still the best advice. but give us more granularity about what you're seeing in the hospital. do the kids tend to be vaccinated or unvaccinated? are they older or younger? where are those dividing lines? >> yeah, that is a good question. when we talk about in particular the children with the most severe disease, by and large they are older and unvaccinated. and so i think that we can make a real difference if we get those children who are eligible their vaccines. right now the oldest children, the 16 and 17-year-olds, can even be boosted now if it has been six months since their second dose of their pfizer vaccine. in that group they are all getting pfizer at the moment. so that is an option too. if you have a high school kid who is about to go back to school and they are eligible to be boosted, please think about that as well. >> and of course the big shortage is is that people can't get their hands on these at-home rapid tests. certainly not easily and they are not as accessible as a lot of medical experts hoped that they would be. but they are also not inexpensive. and so i wonder what you have heard from parents about that, if they want to be able to have these at-home rapid tests for their kids, have you heard them talk about how expensive it is given the cost can really add up if you are buying a lot of these tests? >> yeah, certainly that is a barrier. there is two things right now. right now there is a shortage of them, they are harder to find even if you do want to pay the money to get them. but yes, they are expensive. i think that there is some push to get these tests free at local libraries or health departments. but i think that the supply right now is limited. so that is a challenge. you know, the other thing too is that, you know, you may not have to just do it once. you may have to do it multiple times. and i think a lot of people are doing that for gatherings, you know, for their holiday gatherings, testing everybody, but we need a steady supply of this embeca them because you may have to use them again and again. so i think that that is a significant challenge. and if we can overcome that supply challenge. and also the cost challenge. i think that that will help us tremendously. >> yeah, i think that it has been a big question especially since you've seen other countries make them either free or basically free, a dollar a test, that kind of nature. doctor, thank you so much for what you are doing and for joining us this morning to just catch our audience up on what is going on. >> you're welcome. meanwhile, the skies not so friendly or really even close these days. [ bleep ]. >> you're going to jail. [ bleep ]. >> can't even imagine being on that plane. and we'll update you on the federal charges that woman is now facing for spitting and hitting an elderly unmasked man. and a top progressive is urging president biden to focus on "build back better" saying that he should use executive action if he has to do pass his plan. the deputy whip of the progressive congressional caucus is joining us next. and ahead, lapd released body cam video of a police shooting that killed a 14-year-old bystander while she was in a store's dressing room with her mother. what we're now learning about how the chaos unfolded in this tragedy. for my phlegmy cough. what about rob's dry cough?

>> eventually we may have to get there. but right now, i still see a window of opportunity perhaps by bringing the bill to the senate and manchin has been back and forth on the "build back be better." at one point he gave our president is counteroffer. he has been at odds with his public and private statements. so i think that there is still time to continue to push, to see if there is a way to get to a consensus here. >> so this seems maybe like a last resort if they did have president biden taking executive action. but i do have some questions on what the details of that would look like because jayapal said that she would release a plan explaining what actions could be taken. do you know any details of what that would look like? >> we'll wait for our chair's report to come out. but certainly presidents have in the past resorted to executive action when the law permits it and when congress has been unresponsive to their request to have some proposal adopted there. so certainly this is one juncture in history as we still fight the pandemic, as the pandemic continues to sweep the country, where we have to look at all possible options. and that is certainly one of them. >> do you know when they plan to release that plan? >> we have no idea yet. but we'll be working on it and the progressive caucus has been an entity that continues to push for "build back better" program as we can make it happen. and there is a bunch of proposals, provisions in the "build back better" act that i think are good for the american people, for families, for children, to have to access child care for seniors and have to get eye care and hearing care. and for people to be able to negotiate the costs of their prescription drugs. these are all important things to the american people and we should address them either legislatively at the floor of the u.s. senate or eventually through an executive order. >> and sjayapal seems to agree legislation is needed for enduring action. and enduring the key there. is there still a sense in your caucus that you can revive the "build back better" bill as it was? >> i believe so. i think that virginians will be hurt if we don't pass this bill. we'll have to speak to the parents of 94,000 kids that will not have child care available. you know, there is over 25,000 students that will access spell grants. you also have 105,000 low wage workers that would get a boost in their earned income tax credit. these are all west vvirginians would be hurt if this bill doesn't pass. so eventually manchin will have to answer to them as well. >> what is the least that you'v heard from nancy pelosi on this? >> we speak on a regular basis and i spoke a couple days ago with her. and she has been very responsive, she continues to push. i think it is important that each senator tells the american people with their vote how they feel about this important piece of legislation, that will help us bring long awaited relief and help us emerge eventually out of this pandemic. >> we know senator manchin has made it clear he is a no on how it stands right now. if there was a scenario where he comes back to the table to talk about doing something, reconciliation where it is only democrats voting for this bill, would you see yourself agreeing to narrow down the bill to just a few priorities has manchin has suggested if it would mean getting him on board and getting it passed through a legislative method instead of executive action? >> we'll have to see what those details are if and when we get there. it may be a combination of both, building consensus around senator manchin and others, and then some executive action for president biden. but certainly we need to ensure that the american people get the help they need as we continue to see omicron sweep the nation. i think it is very important. for example, in my district 77,000 families benefit from the child tax credit, over 123,000 children benefit from it. and that is so important to lift children out of poverty. so these are the kinds of provisions within the "build back better" act that are critical at this juncture as we try to recover. >> and we know that child tax credit good firpir expired in d. and so there are questions about that future. and you think that there is a legislation difference path and also executive action. congressman, thank you so much for joining us.difference path also executive action. congressman, thank you so much for joining us. an ugly incident in the sky where a fight on an airplane was captured on video. and we're seeing more and more of them lately. and what secrets could a newly uncovered confederate statue time capsule hold in virginia?

>> good morning, thanks for having me. so really the trick here is to just stay on top of the problem. if you are flying, best thing you can do is check your reservation periodically. say you are flying new year's eve, i'd be checking your reservation once a day at this point. log on to the website, make sure your trip is okay. a lot of these scheduled changes are proactive, so they are being canceled a little bit in advance, so you can have some time to deal with the situation. >> that leads to the question, how can folks plan ahead? if you find out your flight is canceled and you are about to be stranded for multiple days, what do you do to make sure that you can eventually get back home? what is your best advice? >> so the best thing is if you do find out early, it means that you have time to contact the airline. a lot of the time you will be rescheduled automatically and sometimes that is great and it works and you are done. new flight works and everything is perfect. but sometimes it is not an ideal schedule so you need to kabts t act the airline. best thing do is just try to use the call back feature, message them on social media, and it could take a little while, but at least you are home, not stuck at the airport. if your flight is canceled the same day, it is a little different. you might need to find a customer support agent at the airport, find someone in uniform and just get help that way. >> i will say that the call back feature is a god send. but if folks are stranded at the airport, that seems like the worst of all worlds during this pandemic. because usually, look, holiday season, flights get canceled because of bad weather, we got that. but now we've got that and a pandemic. so just give folks perspective, how does it all compare with holiday travel delays in the past? >> so far it is a little bit really on par with what we've had. it is not even the worst holiday travel season that we've seen. if you remember back to 2013, there were a series of blizzards that absolutely knocked travel out. you mentioned before that we're at about 3,000 canceled flights right now. in 2013, it was actually 10,000. so the situation has definitely been worse. right now it compares with fairly moderate to major blizzard. >> the very thin comfort that comes from realizing that it could be worse. but let me ask you this, if folks find out their flight has been canceled and they are stuck at the airport during a pandemic, what should they do? from a health standpoint as well as a practical standpoint. stick around, sleep on the floor or get out of dodge and wait to fly another day? >> you know, it really depends just on what flight they can get on. a lot of the time, you know, best thing to do might be avoid the big line cuing up to the customer service. maybe you can find a gate agent for a different flight and see if they can give you a number to reach customer support. a lot of times there is an emergency number that is faster than the line just baus you are at because you are at the airport. and if you head to the lounge, a lot of those agents are more empowered and there is a shorter line. >> and obviously if you are inside, please wear a mask. final question, how do you think that this will play out? we're on day four of delays at least. >> you know, i think that it will compare to the spread of the pandemic around the country. i think that as different cities see different hits, everyone will keep being affected. right now it seems as if cancellations are leveling out a little bit. but if the virus spikes in other cities and around the country, i imagine that it will be the same with more pilots and flight attendants getting sick. >> that is not the cheerful news i wanted to hear heading into new years but thanks for telling to us straight. thanks very much. and maybe your flight being canceled is a blessing in disguise because there has been yet another instance of violence on a plane, this time on a delta flight from tampa to atlanta. a woman is facing a federal assault charge for what she did on that flight. ryan young is joining us live from atlanta. like most of these, we're seeing a lot of these recorded on someone's phone and so what does this video show about what happened on this plane? >> reporter: well, let's be honest, you see this sort of -- it got out of handhe videos we've seen. and the video we're getting ready to show you also matches a complaint that was filed by the government. in this video taken by atlanta uncensored that was posted to instagram, you can see things get out of hand pretty quickly. take a watch and listen to what happened on that plane from tampa to atlanta. [ bleep ]. >> as soon as we get to atlanta, you're going to jail. [ bleep ]. >> karen. you're double going to jail. [ bleep ] [ bleep ] [ bleep ]. >> she scratched my face. [ bleep ] [ bleep ]. >> put your mask on. put your [ bleep ] mask on. >> yeah, you see that video, that is patricia cornwall, the woman arrested. she got caught behind a benverae cart and apparently she was upset that she was not going to be allowed back to her seat and she made a comment about rosa parks saying that she felt like she was being caught behind the cart and being treated like rosa parks. the man apparently said sit down karen and then things escalated from there. you heard all the bl bleeps. and apparently she took a swing at him and had to be restrained. and we should put on the screen all the incidents that have happened throughout the year, it is really increasing. and you talk to flight attendants and they say that it is getting more and more dangerous. but obviously this bad behavior that folks in the flight industry would love to stop. but it seems like almost on a daily basis, you have someone who didn't want to wear a mask or sit down and then of course it gets worse and worse. this video caught a lot of people off guard. the man was in his 80s before someone actually stepped in as to stop her from attacking him. >> flight attendants are there trying to protect themselves with the beverage cart from this woman. i just think that it is insane. most people just want to get on a plane, put their headphones in, read a book. drink some gingerale, behavior. >> those were the old days i guess. >> ryan, thank you for the latest on that. just ahead, we have other new body cam video of what led to the tragic shooting of a 14-year-old girl trying on dresses in a department store. and why you will be seeing more on the january 6th committee in the new year. i don't just play someone brainy on tv - i'm an actual neuroscientist. and i love the science behind neuriva plus. unlike ordinary memory supplements, neuriva plus fuels six key indicators of brain performance. more brain performance?

>> reporter: yeah, we're getting new insight into chaotic scene at the california department store last week as a suspect went on a rampage, assaulting a different customer. i want as to warn our viewers that the new footage is graphic, it is disturbing. this is the moment where you see officers going in that store trying to stop a threat but firing the fatal shot that also killed a s14-year-old child. >> she's bleeding, she's bleeding. >> reporter: new body cam video edited and released late monday shows the events that led up to the police shooting of a 14-year-old girl last thursday at a north hollywood, california store. >> lapd! >> reporter: the footage shows the suspect assaulting several women at a burlington store before police arrived guns drawn. 911 and radio calls around noon thursday reported an assault in progress. and then confusion over whether there is a possible active shooter. police body cam footage shows when they arrived they saw the suspect hitting a woman and found her hurt and bleeding after she was hit repeatedly in the arms and head with a metal lock. police located the suspect nearby. and at least one officer fired several shots and killed him. no gun was found near his body as officers searched the scene. then police made a disturbing discovery. >> unbeknownst to the officers, a 14-year-old girl was in the changing room behind a wall that was behind the suspect and out of the officer's view. she was in the changing area with her mother when the officers encountered the suspect and the shooting occurred. >> reporter: they believe that she was hit by a bullet that ricocheted off the floor and entered the dressing room wall. >> she discovered that she had been struck and was deceased at the scene. >> reporter: the 14-year-old girl was shopping with her mother when she was killed. she died from a gunshot wound to the chest. the los angeles medical examiner listing her death a homicide. police also described the suspect's earlier movements and released closed circuit video from the store. >> he smashed a computer video, he hit the glass , next he took the escalator down and encountered another female and she resisted. >> reporter: the attorney general's office and department of justice are now investigating the shooting. and the child's family now mourning the loss of a young girl killed while out shopping just two days before christmas. now, john, one of the major questions raised by this video is whether an officer with a high powered assault rifle firing inside a department store should have been aware what was beyond his target. but of course one thing is clear as you look at this footage, as you listen to the 911 calls, those officers rushing to the scene were operating with information indicating that there were shots fired. they were looking for an active shooter. they were trying to stop a threat. but obviously this shooting leading to a very tragic outcome. >> it is indeed a horrifically tragic outcome, but certainly appears to be an unintentional killing of this 14-year-old girl. we know lapd internal affairs is reviewing the shooting, being classified as a homicide, but also understand that california a.g. is launching an investigation. what does that tell us about the circumstance? >> reporter: well, this actually follows a law that was signed last year by the california governor that indicates anytime there is an officer-involved shooting in the state involving the death of an unarmed person, state prosecutors will launch an investigation. now, that suspect had this bike lock that he was use as a weapon, he was armed but obviously with the death of this child she was obviously unarmed. so that triggers the new investigation. we know state prosecutors are already on scene, they will conduct their investigation, hand it over to state prosecutors, who will determine whether any charges are rnlts with aed in this case. >> so the new law leading to accountability potentially. obviously members of this young girl's family are speaking out. what are they saying? >> reporter: yeah, we're hearing specifically from this young girl's uncle, he spoke to reporters in chile taking the lapd to task saying that this is supposed to be a department with high standards, describing it as one of the most renowned law enforcement agencies in the world asking how could this have happened with an agency with this much training, how did it result in this death. the family obviously in mourning and grieving, demandi ing answe. we expect to hear from them this morning, there will be a press conference at city hall. and we'll hear from members of the family and their attorney obviously demanding answers after the tragic death of that 14-year-old child. >> josh campbell, thank you very much. be well. now for five things to know for your "new day." number one, cdc cutting recommended isolation period from 10 to 5 days for asymptomatic persons amid major concerns of staffing shortages around the country. and cdc also saying that we should reduce quarantine days for those folks who are vaccinated and exposed to the virus. and no survivors have been found after a small plane crashed near san diego, it went down monday night in a neighborhood between el cajon and lakeside. road closures are in effect and residents are asked to avoid the area. no word on what caused the crash. get ready to hear more from the house committee investigating the january 6th capitol attack. the "washington post" saying that the panel will hold public hearings in 2022 to tell the complete story of the insurrection. members want to show that they have connected a lot more information than the public yet knows. a second time capsule has been found when the statue of robert e. lee once stood. this time a copper box weighing 36 pounds. strays x-rayses show what could be inside. and another karen was found two weeks ago at the same location inside was an 1875 almanac, two books, a coin and a cloth envelope. the second container will be opened this afternoon. you called and volunteered to participate. of your own free will. so this is it. >> director of the global sensation "squid game" is teasing a potential third season. he says the creators of the popular series are currently in talks about it.
