peak levels. and even on this day after christmas, people are lining up to get tested. airlines are also struggling with the surge and sick-outs, which means airline travel is beginning to plummet. thousands of cancellations. let's start with you. . >> we're talking about thousands of flights canceled today alone. think about all the people who travel on the day after christmas, and it's all coming together with so many people thinking they would be able to go see family and friends and get back to work with business as usual starting monday morning for many americans. unfortunately, a thousand flights canceled today. that brings the total up to about 2,000 for the weekend of cancellations and delays, and then you add in those international flights that were canceled as well. we spoke to some travelers that were just frustrated, right? they finally wanted to get out and meet family members, some of them for the first time in two years, but their flights were canceled. one woman who was supposed to leave from atlanta and head back to wyoming, she had to call her employer and tell them she wouldn't be able to make them because her flight was delayed. the lines on tsa and regular general boarding was so packed, we spoke to one man who said his flight was delayed but he still didn't have time to get through the screening process. he got to the gate, they looked at his i.d. and said, yeah, you're not going to make this flight. he turned around and was actually happy about it because he wanted to spend one more day with her family. we spoke to one woman who said this was the first time she saw her family for a long time. let's hear how much it meant to get on her flight that was not canceled to see her family again. >> this is my in-laws, the first time i've seen them in about two years. it's been a while. i saw my mom over thanksgiving for the first time in two years. i got my booster shot, that was first and foremost. i was due for it, so i got that. had my mask. i actually switched my seat to be next to one person instead of three people just to keep my distance. yeah, my whole family is vaccinated and we felt safe. it was just immediate family, like ten people. >> reporter: a lot of people were talking to me about getting vaccinated, even kids. even kids, because kids were partially vaccinated. they may have had one shot before thanksgiving, now those kids, 5 to 11, were fully vaccinated. they were eager to share that with me, but still frustration for the many others who were not able to get on flights, experiencing delays and cancellations and the ripple effects that will continue for the next couple days. >> now let's move over to allison. it's not just airlines being disrupted, it's cruise ships. what are you learning about that part of the story? >> cruise ships being disrupted by covid-19. over the past week we saw at least four cruise ships turned away from ports of call and passengers prohibited from did he say -- disembarking because of covid cases on their ships. it was just last year that cruise ships resumed service. it was resumed to mitigate any kind of covid outbreak. since then there have been covid cases. case in point, in august, on a carnival cruise ship, there were 27 covid-positive passengers. those passengers were isolated, other passengers were allowed to disembark after showing proof of a negative covid test, but the difference now is the omicron variant. we know it's more transmissible. a carnival spokesperson telling cnn in a statement that the spread of the variant may shape how some authorities may view even a small number of cases. carnival ship freedom was one of the cruises impacted this week with what carnival calls a small number of passengers with covid-19, and that ship docked earlier this morning in miami according to plan. passengers coming off that ship after that eight-day voyage, they all spoke differently of their experience. listen to what they had to say. >> we've heard varying stories, we heard five, we heard 12, we heard 25. >> it was safe. we had a good time. we would do it again. >> i didn't go into one pool the whole time. everybody is all over each other, nobody is wearing masks. it was disgusting. nobody cared. >> reporter: although we are seeing this uptick in the number of cruise ships that are altering their itineraries because of the omicron variant. it really is just a small fraction of the dozens of cruise ships that are making they're wa -- making their way on their journeys. those ships were actually trying to find ports of call to take passengers and crew just so they can get home. we're in a very different position at this point compared to march 2020, ryan. >> all right, alison kosik, nadia romero, thanks to you. in the early days of the pandemic, carriers are facing threats of lawsuits, even death, from the very people they are trying to save. senior correspondent ed lavandera has the story. >> my name is jeff. >> reporter: dr. jack lyons spends his days treating covid-19 patients in the hospital in minnesota. like so many other doctors, he feels the strain. >> reporter: what's it been like to work in this atmosphere? >> it is exhausted. it is frequently heartbreaking. it is demoralizing at times. >> reporter: dr. lyons says it's also getting hostile as patients are requesting bogus treatments. >> reporter: is it like picking items off a menu at a restaurant? >> absolutely. folks act as if they can come into the hospital and request any sort of therapy they want, or conversely, decline any therapy that they want with the idea being that somehow they can pick and choose and direct their the therapy, and it doesn't work. >> reporter: that's putting health care workers at risk. hospitals are facing a slew of lawsuits, demanding risky treatments. across the country there are reports of growing hostility between medical workers and patients and their families. it's a daily dose of threats and v vitriol. >> it insults your intelligence, and they're saying by not using these therapies, you're intentionally trying to harm the people we see. >> reporter: what has been the worst experience you've had? >> the most difficult experience we had was a patient, a family, who under a pseudonym had main threats against the hospital. there were references to making sure the hospital was locked, and we've got people coming for you. >> reporter: was it a death threat? >> i'm not sure how people would take, we're going to march into the hospital, we're coming for you, as anything other than a death threat. >> reporter: barbara chapman is a nurse practitioner and works at the university of texas at tyler. last summer she started a hotline, offering teachers and health care workers mental health support. >> i used to think of it as being overwhelmed, the health care workers are overwhelmed. that doesn't even address it. the way i address it now with folks when i talk to them is i refer to it as moral injury. >> reporter: what do you mean by that? >> we want to help those. now that folks aren't getting vaccinated, they're not believing us, they're questioning our education and our background, it's hurtful. we're exhausted. we're tired. and so we have been morally injured. >> chapman says some nurses have endured so much abuse that even getting them to walk from hthei cars into work is a challenge. >> it's like when a veteran comes back from the war. he may be out of the war but he ha hasn't left that war. >> it's crazy to me that you're talking about a health care job as if it was walking into a battlefield. >> it's a battlefield. it is a battlefield. >> reporter: dr. jack lyons often thinks of the pandemic's early days when grateful communities banged pots and pans to honor front line health care workers. >> reporter: the vast majority of workers we take care of now come to our interactions distressed. >> that feeling of goodwill is go gone. >> long since dissipated. >> unbelievable. joining me now is dr. rob davidson. he's at the university of wisconsin. doctor, tell me what you make of what we just saw. vitriol against some health care workers and what they're facing now. how do you explain it? is there a way to explain it? >> you can just hear it, and dr. r ryan, when he has a deep sigh and has to reflect on how it's come to be. we're seeing people in a hospital in western michigan in an area with a vaccination rate of 45%. a very high rate of votes for donald trump in the last election. and people ask for things like nebulis iodine. in normal medical practice, we constantly talk to people about treatment. people refuse treatment. this is something different. people are coming with specific treatments that we know not to be helpful, and in some cases, would be extremely dangerous, and they're getting this from the rapid disinformation that's being spread, you know, from senator ron johnson in wisconsin to governor ron desantis in florida telling people that there are treatments out there that truly don't exist, that truly don't help. they're refusing vaccines and they're coming in and declaring that we are trying to hurt them or their loved ones. it is demoralizing, as dr. lyons said in that piece. >> i can't imagine how frustrating that might be for someone who spent all that time going to medical school and practiced at this profession for so long, to have someone come in telling him they read something on the internet that could help them. it's baffling. let's talk about what's going on on the ground right now. hospitalizations of covid-19 up 35% from last week. that's not as high as the cases from omicron, but it's still taxing, i would think. what's it like in hospitals in michigan, and what are your biggest concerns and challenges right now? >> i tell you, we are still deeply mired in a delta surge. the case numbers themselves and the positive rates are trending down a bit. i think we're just under 19% now for test positive, but this still appears to be delta. the problem is covid patients across the board for the past two years end up staying in the hospital for extremely long periods of time. our hospital beds are still extremely full. finding beds for patients on a daily basis is always a challenge. we have flu seasons where you have a weekend that's like this or maybe even a week where it's really tough to find a bed in your hospital or a hospital an hour away or so. this has been days straight of trying to find people beds and boarding them in the er. when people board in the er, people wait in the waiting room, and speaking of threats of violence, we had a patient a few weeks ago who found out they would have a long wait. they said, i'll go home and get my .9-millimeter and do something about it. the police were called, and he said he didn't mean it, but it's things like that causing the system to break down. >> reporter: it's shocking. you're trying to help people and they threaten you with gun violence if you don't do what they ask you to do. i want you to listen to something anthony fauci said today about testing. >> we should be using testing much more extensively than we have, even in a situation where you have people who are vaccinated or boosted. but the situation where you have such a high demand, omicron stirring people to get appropriately concerned during the holiday season. we obviously have to do better. i think things will improve greatly as we get into january, but that doesn't help us today and tomorrow. >> d >> doctor, here's a real problem, isn't it? you either have to wait in a long line for testing, get it through the municipal government or pay some exorbitant price, $20 to $25 for a test. which may be out of people's price range. they're trying to do the right thing, get tested before seeing their loved ones. this is a real problem, isn't it? >> it certainly is. testing is an issue that this administration and governors in the states have to deal with, and we need to get more tests out there, make them more available. we're never going to test our way out of this pandemic. the bottom line is we need more people vaccinated. we need to stop the flow of disinformation about vaccines and get out the idea we can treat covid instead of prevent covid. then the need for a test will kind of go away over time. zero covid-19 is extremely unlikely at this point. but keeping people out of the hospital, keeping people from dying, that is absolutely possible. we see it every day when 98% of our icus are filled with unvaccinated covid patients when they're there for covid. to me that is the most critical, most important thing we can do is get more people vaccinated and stop the flow of disinformation that's preventing it. >> it seems like everything goes back to the vaccine. testing, long hospital stays, whatever the case may be, the answer is get vaccinated, get your booster, that's your best opportunity to avoid being seriously second. yet some people still have a hard time coming to terms with that. dr. rob davidson, thank you so much for spending time with us on a holiday weekend, and thank you for the information you provided. we appreciate it. >> thanks, ryan. >> in an unprecedented move, an accused school shooter's parents are being accused right beside him. documents show why prosecutors felt it was necessary. you are live in the cnn newsroom. is the planning effect. this is how it feels to know you have a wealth plan that covers everything that's important to you. this is what it's like to have a dedicated fidelity advisor looking at your full financial picture. making sure you have the right balance of risk and reward. and helping you plan for future generations. this is "the planning effect" from fidelity. pain hits fast. so get relief fast. only tylenol rapid release gels have laser drilled holes. they release medicine fast for fast pain relief. and now get relief without a pill with tylenol dissolve packs. relief without the water. nurse mariyam sabo knows a moment this pure... ...demands a lotion this pure. new gold bond pure moisture lotion. 24-hour hydration. no parabens, dyes, or fragrances. gold bond. champion your skin. fries or salad?

(all) to screening! newly released court documents revealing never before heard or seen information in the deadly school shooting in michigan last month. 15-year-old ethan crumbley has been charged with the crime, and in an unprecedented move, his parents have been charged right alongside him. >> reporter: disturbing images, disturbing details coming in these court documents which essentially is the state's response to the defendant's request to lower their bond which currently is at $500,000. and we do, we see those drawings that we did know about. again, those drawings are ones that the teacher spotted the morning of the shooting on ethan crumbley's desk. this is the first time we're actually getting a look at them, though. if you see what prosecutors show in this court document is the first drawing which shows very disturbing images like a gun and a bullet and the words "blood everywhere, my life is useless." then they said that drawing was altered to appear not to look so bad. you can see, it says, i love my life so much. we're all friends here, and the disturbing images are scribbled out. again, this is just part of the evidence that prosecutors are laying out in this case. other parts of it include details about how the parents, they allege, knew about the troubles their son was going through, and yet ignored all those signs, prosecutors saying up to six months before that shooting happened in late november. let me read you an excerpt of this court document. it said, quote, defendants have information long before november 30th, within the six months prior to the shooting, that their son's only friend moved at the end of october 2021, that the family dog died, that their son was sadder than usual, and that he was sending his mother disturbing texts about his state of the mind. meanwhile, in that same period, his parents took care of horses three hours at a time and seeking other relationships, including his mother's extramarital affairs. instead of getting the son help, they bought him a gun. authorities said these parents could have possibly even prevented this shooting in that michigan high school, killing four and injuries many others. the prosecutors also making an argument in this document as to why that bond should not be lowered, stating that the parents were $11,000 or more in their house payments, that they actually tried to work and list their home the day of their attack, and that they're a flight risk. of course, we remember, those parents were not to be seen for several days until authorities found the man a warehouse in detroit, and prosecutors say in this document that they had several phones on them, two of them burner phones, after they even withdrew a lot of cash. again, all of these details are becoming new as we're learning more evidence about the prosecutor's case against not even just the parents of ethan crumbley but ethan crumbley himself, and of course it will be up to a judge to decide if their bond should be lowered. i'm brynn gingras, cnn, new york. >> eva martin and jillian peterson is a founder of the project. reva, we'll start about you. how critical is this charge against ethan crumbley's parents? >> we know it's not uncommon that parents are involved in the children's homicide cases. we haven't seen charges brought in school shootings, like in this case, but the evidence is so overwhelming against these parents in terms of complete disregard over their son. it's not against the law to have extramarital affairs, it's not against the law to be an incompetent parent. all the warning signs were there. they knew their son was extraordinarily sad. they knew he had access not just to their gun but that they had bought him his own weapon and that that weapon was not kept in a locked cabinet or drawer. so when you add up these facts and the facts that one hour before he committed this crime that they were at the school. they didn't ask their son where the gun was, they didn't ask to look in his backpack, in fact, they insisted he remain in the school even though they knew he had access to this gun. when you look at all these facts, i think the charges were appropriate and i think the case against both of these parents are incredibly strong. >> jillian, you study violence, you're also a mom of three. what are your biggest takeaways from the details laid out in these court documents? >> you know, our research on mass shooters and school shooters is life histories that are actually very consistent with this, that perpetrators tend to have really chaotic backgrounds, come from households that are chaotic, they are in crisis in the weeks leading up to the shooting. and there's triggers for that, so things like a friend moving away or a dog dying would be examples. they become suicidal, their behavior is changing and people around them are noticing it, and they start making plans, which happened that morning with the note that he made in class. this is all really consistent with the patterns that we see that makes us hopeful that some of these cases may be preventable in the future. i think what's different in this case is the school counselor literally laid this all out for the parents an hour before this happened and they did nothing. >> yeah, and that's why we're in the situation now where the parents had been charged in this case. reva, is there enough here in this case, enough laws on the books for this to become a legal precedent. this isn't something we've seen before, to charge the parents for their child's alleged violent acts. >> we've seen other parents charged in regard to acts of their children, so it's not uncommon to see parents held responsible for their children's actions, we just haven't seen it in some cases. based on these individual cases, and i hope we don't have any more school shootings, until something happens with accessibility to guns, we're likely to see more shooting cases like this. this is definitely a wake-up call for parents, parents who ignore the red flags, who see their children are extraordinarily sad, who have access, who give their kids access to a gun. i think parents are on notice that if you engage in conduct similar to what these parents engage in, you could find yourself facing criminal charges. >> so, jillian, as somebody who studies mass shootings, you mentioned the fact that the school officials put this problem in front of the parents and they didn't really do anything about it. is holding them accountable in a situation like this going to make a difference in helping to prevent the next incident from happening? >> you know, it's hard to know. i think this may have implications for laws around things like safe storage of weapons and what is the responsibility of parents who make guns accessible in the home and, in this case, even give children a gun, making them responsible for what happens with that gun. i think this could have implications around how parents speak to their children about guns. >> what can parents do if they see red flags around their children? >> i think you want to make sure you're responding to red flags. you're looking for marked changes in bhehavior, and you want to reach out and give support, whether that's from a health professional, someone at the school, someone in your kmuchbt. you want t -- community. you want to make sure you're not missing warning signs, that you're digging in and asking questions and really sort of helping that child navigate that space that they're in. >> i can't think of two better people to have a conversation around this topic. terrific insight from both of you. reva martin and jillian peterson, thank you so much for being here. if you're concerned about the mental health of loved ones, the substance abuse mental health hotline is 800-662-help. it has information in both english and spanish. it is 24/7 and every day of the year. still to come, after senator joe manchin said he was a no on biden's build back better agenda, what happens next? democrats are already strategizing their next move. you're live in the cnn newsroom. could the new year give the president's build back better plan a new lease on life? some democrats haven't given up hope that some key pieces of the economic agenda will still make it through the senate in 2021. before the holiday, president biden said he was still working on joe manchin's no vote. >> that period came and went and still no build back better agenda. instead it appears we're in a bit of a holiday pause on those talks. however, discussions have been ongoing sibetween the white hou and senator manchin, even though senator manchin blew up the state of affairs, essentially, saying he could not support the build back better act in its current form. since then we know that president biden and senator manchin, they did speak following that interview, and president biden has expressed some optimism that he believes they can ultimately get large chunks of his agenda done. how, though, appears unclear. that's where the strategizing comes in, and we know democrats are still considering a variety of ways they can push the agenda next summer. are democrats open to scaling it back even more or passing various pieces of standalones, maybe attracting senator manchin and even the gop on some of these issues? >> that's a strategy decision that's being negotiated. we are hope to a way to reach the finish line. we want to make it as comprehensive as possible because the needs are just there. >> ultimately, though, democrats have to be clear out here. it's going to be difficult for them to break this up into different parts, particularly if they want to use that reconciliation vehicle with a simple majority to get this through. those conversations will have to be ongoing for the white house to find some path with senator manchin to bridge the difference there. we also heard today from an op-ed from congresswoman jayapal before the congressional office, she said they wanted to find a better framework to agree to, if possible, in the new year. she also said she's going to push president biden to act on executive action to get some of this done. we know that they will vote on a new bill for the build back better bill, however a date hasn't been set for that. >> we're here with julian to talk about the build back better plan. it seems it's still not on stable ground. is it time to rewrite this vision that the president had for it? >> not yet. the president is in a difficult position. there is always the possibility of some kind of shift, but it's difficult. the president will have to negotiate with manchin who has been very difficult and not very clear in terms of what he wanted. so we're probably at looking either redirecting funding in parts of the program in ways that are appealing to manchin. other than that, they have to work around him rather than working with him. >> that, of course, difficult in a 50-50 senate. they need his vote to get anything through. senator biden has played up the senator experience, right? he acc-- why does he come up sh on this? >> even president lyndon johnson understood that when a member of congress was firmly against the president's agenda, there wasn't much you could do if you didn't have the numbers. i think he's running into that. you have evidence and manchin is just want. there's things the president can do beyond executive power. >> i realize he's only got so many cracks at the apple when it comes to reconciliation. on the other side of the coin. >> there is an argument that he should have moved more quickly and with more force early on when it was still early in his presidency and when he still had more leverage from that post-election moment. timing is everything. so i think different people will have different views. he did too much, but others would argue he didn't work with enough force early on. but, again, there's still time. he's still president, he has many years ahead of him, and so now the challenge is what to do in january to maximize the opportunity for legislation. >> there's no doubt, right, that him setting these standards for himself, to a certain extent, it's a self-fulfilling failure, right? he did pass infrastructure package that both democratic and republic karn people have failed. are we perhaps being harsh on joe biden and his administration, approximate. >> we can look at the record and say it's already very substantial. eetz had two peetsz of legislation and that doesn't mean that the issues that are so critical that are addressed in that final piece, from child care to the climate, those are essential as well. i think this is a president with grand ambitions. you don't start small, you start big and you see what you can get. so i think it was a good strategy, but he also may come up with stuff he wants. now the clock is ticking, right, julian? his party does hold the majorities in the midterms, but that the seems to be the seni minority. how critical is it to get something done before 2022 and those midterm votes? >> it's hard to say what he could do in ex changs of a m-- exchanges. this is the window, probably, of a couple months to get it f. and how we think about him years from now. i think he understands what's at stake and i think he's going to continue to pursue this. >> i guess the big question in the new year is how does he get t to those big goals? does he continue to push that big package or does he go around it? thank you so much for being here. we trans late it. and here's another thing. he's only 11 years old and he's a superhero. you're live inially. ww's all-new personalpoints program is made just for you. you take an assessment, enter your goals, the foods you love and ww builds a plan just for you. i lost 26 pounds and i feel incredible. oprah: no two people are alike so no two plans are alike. with ww, i lost 30 pounds. this new program changed my life. live the life you love. lose the weight you want. the all new ww personalpoints program. download the ww app today for a 14-day free trial. to see my ancestors' photos was just breathtaking. wow, look at all those! what'd you find?
