interview. and then, red flags raised a michigan sheriff revealing new details today about why the teenage suspect's parents were called to the principal's office just hours before the deadly high school shooting. welcome to "the lead." i'm jake tapper and we start with the health lead and the biden administration saying it is pulling out all the stops to accelerate our way out of this pandemic and slow the spread of omicron the new variant health officials still know so little about. new evidence today suggests, however, the new variant clearly is spreading in the u.s. president biden went to the national institutes of health this afternoon to announce his new plan launching a national campaign for boosters, setting up family vaccination sites, expanding covid testing, making the at home test kits free either reimbursed by insurance or provided by the government for those who do not have insurance. also today the proposed cdc rules for international travel became official and now everyone flying to the united states including american citizens who are fully vaccinated needs proof of a negative covid test taken one day before departure instead of three days. cnn's nick watt starts us off with the more aggressive approach. >> announcing today that all inbound international travelers must test within one day of departure regardless of their vaccination status or nationality. >> reporter: one plank of the president's winter action plan announced this afternoon to fight the coronavirus and its new omicron variant which we now know is here, a second case confirmed this morning in minnesota. mile symptoms, now recovered, vaccinated man recently returned from a large animae convention in new york city. >> potentially now on both coasts and that means we are going to continue to see the number of cases rise. >> reporter: the first confirmed case was yesterday in san francisco, fully vaccinated but unboosted individual recently returned from south africa. also mild symptoms and doing well. >> all close contacts have been contacted and thus far have tested negative. >> reporter: we still don't know for sure if omicron is more transmissible or significantly evades the vaccines. but -- >> there is every reason to believe that kind of increase you get with the boost would be helpful in preventing severe disease of a variant like omicron. >> reporter: right now the delta variant is still dominant worldwide and here in the u.s. here is where we are. averaging a whopping 85,000 plus new infections every day and 911 deaths. >> this winter we'll make free at home tests more available to americans than ever before. >> reporter: more than 80% of counties right now have high or substantial community transmission. >> we'll get to 60 teams ready to deploy in states experiencing a surge of cases over the winter. >> reporter: well over a hundred million eligible americans are still not fully vaccinated let alone boosted. >> we are expanding our national booster campaign to provide booster shots to all eligible adults and expanding our efforts to vaccinate children ages 5 and up. >> reporter: back in january two-thirds of americans felt optimistic about vaccinations. that is now less than half, 31% of us are now angry about the current status of vaccination in this country. this is of course a global problem. the clue is in what we call it, a pandemic. and today president biden also pledged to send more vaccine doses to other countries that need them. meantime, the world health organization is saying it is unfair that the u.s. and other countries have placed restrictions on flights coming out of south africa. they say south africa is basically being penalized for doing the right thing, for identifying this variant and telling us all about it. >> thanks so much. let's discuss. cnn's kaitlan collins at the white house and at dulles international airport with the travel angle and we have the dean of brown university school of public health. kaitlan, the public safety part of this plan, also politics plays a role, communication. this is crisis management 101. get ahead of the issue as we see the new variant emerge. >> yes. this has been the issue for president biden since he took office. the main issue of his presidency he has said. of course the concern here is not just the small subsidies or big measures he is taking when it comes to fighting covid-19. it is also that he is in charge and taking steps to combat the new variant. there is a divide when it comes to democrats and republicans and how the president has been handling this but look at the number when it comes to independents. 39% approve of how he is handling it so far based on the kaiser family foundation poll. 52% disapprove. the number has fallen sharply. i think what that means is the white house is trying to apply the lessons they learned from the delta variant back in june when his numbers were much higher. then we saw the delta variant sweep across the united states and his poll numbers go down. they are trying to show here while we still don't know a lot about the new variant we are taking steps to do what we can while we are trying to evaluate it. >> in july president biden announced independence from the virus on independence day. pete, stricter rules for international travels, part of the new rollout including mandatory testing a day before flying to the u.s. i have two questions. are airlines prepared to require travelers to get a test and a result one day before they leave wherever they are in the world? i don't know if it is possible to get a test and result within one day before travel everywhere in the united states. >> airlines say they're prepared because they've been doing this for months. they were already required to get proof of the negative covid test within three days of departure. now that passenger has to show proof of a negative test within one day of departure. the real onus is not necessarily on airlines but on passengers to find the proper test, find a testing site. we've seen more and more pop up at airports and even internationally here at dulles international airport but the industry is chafing at the travel restrictions and any change because they feel any new uptick in restrictions for those traveling internationally will make the numbers go down. we've seen a strong and robust travel period throughout the thanksgiving travel season. 2.5 million people on the sunday after thanksgiving. they just don't want to lose that really tenuous, thin thread they have on a travel rebound. they think this could get in the way of that. >> much of this seems designed to get ahead of the new omicron variant but researchers still don't know much about it. they don't know how easily it spreads, whether it evades vaccines, and without knowing that do you think these measures may be premature? >> thanks for having me back. i don't think they are premature. we don't know the facts but the little we do know is concerning. we can wait until all the data is in and then we'll be behind the 8 ball. i'd much rather be ahead of the game. if it turns out this is not all that transmissible, that there is not much vaccine evasion we can always pull back. i'd much rather be in that position than playing catch up. >> kaitlan, the president is making the big push for booster shots. he might have an uphill battle convincing many americans that they need one. >> sometimes it comes down to party lines. the president talked about the political divide here today. if you look at the numbers of all adults who is planning on getting a booster you can see the discrepancy and gap when it comes to republicans. 36%. democrats 77%. when you look at the number of republicans already vaccinated, jake, that number is a little bit higher. that is the issue facing president biden as he is dealing with this and part of that is the lagging effort of the confusing messaging around booster shots, something people inside the white house and administration will acknowledge was an issue and just now had cdc change the language to say everyone over 18 should get a booster. before it was may get a booster. they are trying to get the messaging right on boosters so there are a hundred million eligible people who haven't gotten one and can go get one. >> there has been talk although no indication from the biden administration that they want to do it of requiring proof of vaccination not just proof of a negative covid test for international or domestic travel. what do the airlines think about that? >> airlines hate the notion of having this for international travel and domestic travel. one top industry official tells me it would clobber the big numbers they've seen lately. right now it is required for foreign nationals to show proof they are fully vaccinated to the airline before coming into the united states and customs and border patrol officials here at airport have also been required to show proof of a negative coronavirus test. a bit of a one-two punch there. now we are seeing the gap get a little narrowed. it was three days now one day. we'll see if the restrictions stay in place and the biden administration not hinting at anything new just yet and airlines and the industry would like to keep it that way. >> today covid cases in south africa jumped by more than 7,000 in one week. health officials do not yet know if it is omicron, the new variant, causing the spread. do you see any other possible or logical explanation? >> no. i think it likely is. we are seeing it particularly in the state of south africa where omicron is dominant. i am pretty worried this really does show omicron is widespread there and we are seeing hospitalizations rise as well. some concerning features out of south africa. >> thank you to all of you. up next omicron and the vaccine. so many unanswered questions. we'll talk to a top vaccine expert in the country. then, could your next flight run on scraps of food? cnn gets a ride into the future. stay with us. oh yeah, we gotta take off. you downloaded the td ameritrade

booster shots and testing only limiting travel from certain countries. let's bring in rick bright who led the trump administration's vaccine development effort and resigned after a whistle-blower complaint saying his early warnings about the pandemic had been ignored. rick, good to see you again. we should note after the election you briefly joined president biden's covid advisory board. what do you make of the new response plan announced today? is it enough do you think? >> jake, thanks for having me back on. like many plans they're just plans. it is a great start. i think there are great points. it is surprising to see some of those points being rolled out as a new idea two years into a pandemic. i think the most important thing we need to see in america and across the world is action. we need to see leadership and coordination and coordinate action around the world. this omicron variant, jake, is a consequence of not having the world vaccinated soon enough. we'll continue seeing this until we put vaccine equity at the top of our list not just donating a few doses or even a billion doses but putting resources in place around the world to get doses into the arms and not on the tarmac to stop this virus from mutating and coming into new variants and spreading around the world. >> experts have been saying if the united states and other countries didn't do more to immunize the entire world this is what was going to happen and now we are seeing it happening. you are an immunologist and have built your career researching vaccines. from the little we do know about omicron do you think our current vaccines will be able to hold up against it? >> from what i would speculate, jake, as you said, we don't have a lot of data yet. but it is still the sars cov-2 virus and the major protein of the virus, there are a lot of changes and mutations in the spike region which comprises the immunity we make from the vaccines. i would be very surprised if there was no immunity from our current vaccines to this new variant. i would actually be pretty confident we'll have some level of protection or efficacy especially from hospitalized or from deaths. we are on the leading edge so i don't want to be too confident just yet but right now we're not seeing a lot of hospitalized cases or deaths from this omicron being reported anywhere. most cases we are able to see are in milder infections if in a vaccinated person which emphasizes the need for getting vaccinated as quickly as you can. >> indeed. the president of moderna is now trying to clarify comments by the company ceo this week who said he did not think the existing moderna vaccine would be effective against the new variant. here is the clarification. take a listen. >> i think some of the word choice may not have been optimal. it seems likely that the omicron variant is going to make a dent in our vaccine efficacy. in fact in all vaccine efficacy. combination of mutations brought together there are we think going to increase the possibility of immune escape. the one thing we don't know for sure is how big is the dent, the decrease in vaccine efficacy? >> does anyone really know? >> we don't, jake. that is the danger. comments by press relief. comments by ceos from large companies who have a lot to gain in moving the market ahead of a data set. we need to be sure we don't get overly excited about any data on either side right now and should focus on what we can do to protect ourselves and our family from sars cov 2 be it the delta or the omicron variant getting fully vaccinated with the booster dose. i just got mine two weeks ago. wearing your mask. i am in kansas for a family event. i went into walmart to buy some rapid tests. there were only two people in the entire walmart store i saw in kansas with a mask on. that is extremely concerning with the delta variant and more concerning with what we don't yet know about omicron. people, please wear your mask up over your nose and keep your distance and try not to breathe someone else's air right now >> i want to ask you about this controversy involving former president trump and his covid diagnosis from last year. "the guardian" newspaper detailed an excerpt from an upcoming book from mark meadows, trump's former chief of staff and trump loyalist and meadows reportedly rote trump tested positive for covid three days before his debate with joe biden. this week trump called the reporting fake news. meadows now apparently agrees that it is fake news bizarrely enough. >> well, the president is right it is fake news. if you actually read the book, the context of it, that story outlined a false positive. literally had a test. had two other tests after that and showed that he didn't have covid during the debate. >> we should note it was days later that trump acknowledged he had covid. you resigned from your post at the national institutes of health the same week that trump went to walter reed, basically medevacced there with covid. what do you make of this? >> the chaos doesn't surprise me coming from those individuals in the trump administration. jake, i would say if anyone especially the president of the united states knowingly went into and put people at risk, gold star families, other people at the debates, etcetera, at risk knowing that he could potentially be positive for sars cov 2 even with an initial test that is absolutely unconscionable and extremely concerning for any human being let alone the president of the united states to put people at such risk. i don't know if we'll ever know the truthful answer. from what i am hearing it doesn't seem like they were following testing protocols accurately but i wasn't there as you said. i would say unconscionable act of putting people's lives at risk for a leader, world leader such as the president. >> all right. thank you so much. hope you have fun at the family event in kansas. thanks for joining us. up next a cnn exclusive with one of the democratic senators who is key to the biden agenda passing. what is the message senator kyrsten sinema has for democratic party leaders? stay with us.

>> she is one of the most powerful if not mystifying democrats in the u.s. senate especially given the fact that it is a tied chamber right now. but she, while she was part of building that huge infrastructure bill and getting it across the finish line she is not quite ready to say yes to biden's build back better plan. you have met directly with the president perhaps more than any other senator in the democratic party maybe aside from joe manchin. what lessons have you learned? what kind of negotiator is the president? is it hard for you to tell the president, no, i can't do that? >> president biden served in the senate for a long time so he knows how negotiations work. he also during this process called me repeatedly and asked me to continue working with senator rob portman and others in the g 10 to find this bipartisan agreement. and showed a real commitment to wanting this bipartisan achievement, which we have accomplished. i think the big challenge in front of us is for us to all work together in an accountable and transparent way to actually implement this law. >> reporter: schumer has said he wants to vote on build back better the broader social safety net bill before christmas break. are you prepared to vote yes when that comes to the floor? >> i don't set the schedule for the senate floor. i am always prepared to vote. and to vote for what is right for the interests of arizona. i personally believe that the best way to create legislation is to be thoughtful and careful so we're crafting legislation that truly represents the interests we want to achieve and creates a benefit and helps people all across arizona and the country. that is what i'm working on right now. >> it doesn't sound like you are quite a yes yet on the version that just passed the house of representatives. what changes do you want to make? >> folks know i don't negotiate in the press so i am not going to do that with you. >> reporter: i know one thing you made clear very early in the negotiation with the president and your majority leader was that you were not going to support raising the corporate tax rate up a single point. did you feel like at any point they weren't taking your comments seriously given the fact that they were promising for a long time this was going to be part of the bill? >> i don't spend much time thinking about what other people are saying publicly. what i really want to focus on is how to get to a solution and solve a problem that matters to every day folks in arizona. people back home in arizona know that i am committed to ensuring any legislation we pass retains america's competitiveness. so i won't support any legislation that increases burdens on arizonans or american businesses and decreases our ability to compete domestically or globally. i want to be sure if we craft legislation we do it in a lean and efficient way that is fiscally responsible and doesn't impact things like inflation or make our businesses less competitive. >> so you have been criticized from progressives who say you're standing in the way of what we've been campaigning on for years whether that is repealing the 2017 tax cuts, whether that is changing voting rights laws. what do you say to progressives back home who are disappointed in the job you are doing here? >> well, i am serving the exact way i have campaigned on over the last near decade i have served in washington, d.c. when i ran for the united states senate in 2018 i told the folks of arizona what i would do. that i would come to the senate, try to find bipartisan solutions, be an independent voice for arizona, and always put every day people in arizona first. i would say that is exactly what i'm doing. >> one of the ways you negotiate in talking with your colleagues is you are pretty forthcoming on where you stand on something. we talked about the corporate tax rate. why do you think it is that your leadership sometimes over promises? do you think that is a problem for voters and for the democratic party? >> i can only speak for myself but what i can say is this. i would never promise something to the american people that i can't deliver. i think it is not responsible for elected leaders to do that. the concern i have is that, first, it's not very honest. so you should just be honest. that is something my parents taught me when i was very young. it stuck. >> reporter: some of your colleagues, progressives, think you're kind of an enigma. they're not sure where you stand on any one issue while you're in the middle of a negotiation. do you think that is a fair criticism of you? >> i think i am very direct and i am very upfront when i talk to folks about what i believe in, what i can support and what i can't support. so i think there are some people who just don't like what they're hearing and maybe they use other terms to describe it but folks in arizona know that i have always been a straight shooter and always will be. >> would you be willing to vote with democrats to hold up the president's mandates? >> i am not going to tell you those things. what i will do is make sure i vote in the interest of arizonans. folks in arizona know i am a strong supporter of this vac. i encourage all arizonans to get vaccinated so we can return to the lives we love and be able to share those important moments of both joy and sorrow with our family members. >> reporter: jake, she is making it clear she doesn't negotiate in public. she is not going to give specifics about what it is in the build back better plan that passed the house that she doesn't like right this second. those are negotiations happening behind the scenes. she is making that very clear. she is also defending the fact that she says, look. i've always told arizona voters exactly where i stand. they sent me to the senate. i'm doing the job i think they want me to be doing. if they don't like it or some people don't like it, tough. >> did senator sinema share any thoughts about senator joe manchin who is the other moderate democrat maybe conservative democrat currently perceived as holding up president biden's agenda? >> reporter: the two senators often get lumped together because they are both moderates from states across the country, yet they operate so differently. senator sinema doesn't get into details about whether she is having private conversations with senator manchin, whether there is any piece of the build back better plan she is trying to get manchin to support. she did make it clear she is supportive of paid family leave. we know that is a program senator manchin does not want included in the bill but she would not get into details about how or whether she sort of lobbies her fellow members, jake. >> all right. thank you so much. new information about why the parents of the accused michigan school shooter were called to a meeting at the school just hours before their son allegedly went on a rampage. stay with us. voya doesn't just help me get to retirement... ...they're with me all the way through it. voya. be confident to and through retirement. this is your home. this is your family room slash gym. the guest bedroom slash music studio. the daybed slash dog bed. the living room slash yoga shanti slash regional office slash classroom. and this is the basement slash panic room. maybe what your family needs is a vacation home slash vacation home. find yours on the vrbo app. ♪ ♪ well the sun is shining and the grass is green ♪ ♪ i'm way ahead of schedule with my trusty team ♪ ♪ there's heather on the hedges ♪ ♪ and kenny on the koi ♪ ♪ and your truck's been demolished by the peterson boy ♪ ♪ yes -- ♪ wait, what was that?

ethan crumbley's behavior had been so concerning to teachers his parents had been forced to come to the school just hours before the attack. he faces charges of murder and terrorism. prosecutors have indicated they are also considering charging his parents who owned the firearm used in the shooting. the announcement on that could come within the next 24 hours. we'll go live to oxford, michigan. the sheriff is revealing new information about the suspect's prior behavior. >> that's right. we are learning from the oakland county sheriff that the school is saying that the suspected shooter did not have a previous history of displaying any behavioral problems, any disturbing or concerning behavior, but all of that seems to have changed earlier this week. on the day before the shooting and then on the morning of the shooting. not one but two teachers raising some alarm bells deciding they needed to act on what he was saying or doing. listen to what the sheriff had to say. >> on the day prior to the tragedy, a teacher in the classroom where he was a student saw and heard something that she felt was disturbing in terms of his behavior. the day of the shooting a different teacher in different classroom saw some behavior that they felt was concerning and they brought the child down to an office. had a meeting with school officials, called in the parents, and ultimately it was determined that he could go back into class. >> reporter: jake, investigators aren't describing the nature of the behavior at this time. we've heard the prosecutor say there is another piece of evidence that hasn't been shared with the public and is also disturbing in nature. a lot of the question and focus right now of course is on why he was allowed to return to class and whether law enforcement should have been alerted at that time. >> investigators also say they've discovered evidence proving that the shooting was in fact premeditated. >> reporter: this is a 15-year-old charged as an adult with four counts of first-degree murder, very much because they believe this was an attack that he had thought about, premeditated, plotted. they are looking at evidence that includes writing from the suspect. they say they recovered a journal in which he talks about shooting up the school. they say they also recovered two cell phone videos in which he talks about shooting and killing students at oxford high school. investigators are also focusing on the weapon used and say it was a semiautomatic hand gun they believe was purchased by the suspect's father just four days before the attack and this afternoon we're learning that charges against both parents are still being considered and we could hear an announcement from the prosecutor within the next 24 hours. >> thanks so much. let's discuss this with retired fbi profiler candace delong. thanks for joining us. two different teachers raised concerns about the suspected gunman's behavior this week including the day of the shooting. we don't know what that was. obviously kids act out. what do you make of this? do you think the school did enough here? >> well, the fbi along with the secret service did extensive research into this kind of thing, what they call active shooters which would include school shooters. they were able to identify three or four things we see, behaviors we see happening in most of these cases and one of them is especially in school kids, high school kids that close to the time of the shooting they will be exhibiting odd behavior, enough so people will go, what's going on? can be aggressive, aggressive physically, verbally, could be just simply inappropriate. what we do know is on the day of and the day before this attack two different teachers were concerned enough to bring it to the attention of the principal and then finally to bring in the parents. so we don't know. i'm sure we will find out. >> two videos were recovered from the cell phone of the suspected gunman in which he talked about shooting and killing student. what does that indicate to you? >> often times, well, it could be a few different things, often times shooters do this especially teenagers before the event and they may sometimes release it. it can be viewed as attention seeking behavior but the fbi research into this, they have a name for it called leakage. leakage, which is a way the shooter before the attack is somehow or other trying to get a message out, either a threat or a cry for help or something. in this particular case the shooter did not display these on social media. the investigators found them on his phone. >> i guess one of the questions is, how do we prevent these types of things from happening? parents, do they need to play a stronger role in the lives of their kids? if they live with kids do they need to lock up their guns? what are some of your more general suggestions? >> yes and yes to your questions. parents need eseggsly with high schoolers, adolescents, that is a tough time in a kid's life. if things are not going their way, maybe they're being bullied, and i'm not saying this kid was, or having a hard time at school, various disappointments, what one thing we do know research has said is in the year leading up to the shooting often times people had at least three major stressful event. if you have kids at home that seem to be having a problem or you are the least bit concerned and you have a gun in the house, get the gun out of the house. another thing i know a lot of parents are reticent to go in their child's room, kids' room and look around maybe for anything that would be indicative of why is their child being reclusive or maybe violent or not getting along with his siblings, your child's room is your room. you're letting them use it while they live there and you may find something in their room. if you do, do something about it. don't just figure it will go away. no it may not. >> turning to another tragedy, the suspect in last month's waukesha christmas parade massacre just gave an interview in which he said he feels as if he is being treated as a monster and demonized. this is someone who mowed down 60 people killing six. what does that tell you? it is my understanding with the little we know so far there were previous incidents with him being violent with girlfriends. that is not unusual in our society today but this person in particular was frightening to other people. he may be paranoid. that statement i'm being viewed as a monster, treated as a monster, well you did a monstrous thing but he may not see reality as reality is which means he may be psychotic. >> check out her great podcast killer psyche. thanks for joining us. coming up russia and the united states face off in a key

state antony blinken who spoke to a meetreporters after a meet with his russian counterpart. >> reporter: this highly anticipated meeting here in stockholm was serious and sober according to secretary blinken but it did not result in any concrete agreement that would lead to the immediate de-escalation of the crisis nor did secretary blinken lay out explicitly what the serious consequences would be for russia should they decide to invade ukraine. blinken did tell the russians both before the meeting and in it that there would be serious costs from the u.s. and its allies if russia does decide to go ahead with military action. so the goal for now is to keep the diplomatic discussions going in the coming days. blinken said today that there could be a call soon between presidents biden and putin. >> we had candid exchanges on our different perspectives and agreed to report those back to our presidents who may have the opportunity to speak directly in the near future. >> reporter: the two sides will continue to talk. a senior state department official today told reporters there would be intense diplomacy in the coming days with the hope that eventually russia would pull back its forces and agree to a cease-fire in eastern ukraine. for its part russia says it is acting in self-defense and its security is threatened as nato moves eastward toward its border. blinken says it is not clear whether russia has made up its mind to invade ukraine but that it has put in place the capacity to do so and to do so quickly. what the u.s. and nato are seeing right now is very similar to back in 2014 and that of course is when russia did invade ukraine and annexed crimea. >> thank you so much. coming up we'll take you inside the hunt for the omicron variant here in the united states.
