time now for the good stuff. she's a swimming legend known to all as mighty mo. maureen cornfeld and she's celebrating her 100th birthday. she has won 14 world championships, set 28inducted i international swimming hall of fame and nearly swims every day. her secret to long life, just to enjoy it. cnn's coverage continues right now. good morning. i'm erica hill. >> i'm jim sciutto. this morning, we are learning new details about the biden administration's plans to

respond to the omicron variant. top officials are considering strict testing requirements for all travelers entering the u.s. from abroad. a decision on that could come anytime this week. we're going to have everything we know about that plan coming up. also new this morning, chilling video from inside a michigan high school, students running for their lives as a 15-year-old opened fire, killing three students, injuring eight other people. one local official saying in response, however, there are really no -- remarking on the toll it will take shattering the security in that space. we'll hear about some of the warnings the gunman may have left behind. once again, it is utterly disturbing. >> children having to endure that in their school. also in the next hour for the first time in almost three decades, the future of abortion rights in america will be at stake, possibly in danger as the

supreme court hears arguments on the constitutionality of a mississippi state law that bans abortions after the first 15 weeks of pregnancy. a lot of developments we're following this morning. let's begin at the white house with the administration's plans to respond to the omicron variant. and, jeremy, discussion of testing here for international travels, a proposal as well for possible quarantine? where do things stand? >> reporter: there is a number of things under consideration now. the biden administration is considering requiring american citizens and foreign travelers flying to the u.s. to test for coronavirus one day before their trip. currently fully vaccinated travelers only need to test within three days of their trip. so this would shorten that timeline. they are also considering requiring testing upon returning home. a cdc spokesman last night confirmed that they are indeed looking at shortening that testing window, saying in a

statement, a revised order would shorten the timeline for required testing for all international air travelers to one day before departure to the united states. this strengthens already robust protocols in place for international travel, including require s for foreign travelers to be fully vaccinated. we have heard and the cdc director did mention that they were looking at potentially changing rules related to self-quarantine when returning to the united states. but a white house official making very clear that a mandatory quarantine for people returning to the united states or coming to the united states from abroad is not under consideration. that official also making clear that the administration is evaluating a range of options and we are expected to hear what these new strength in testing requirements and other protocols are, when president biden goes to the national institutes of health tomorrow. he's expected to outline his strategy, that will also include a focus on vaccinations, boosters and, of course, testing. jim, erica?

>> jeremy diamond, appreciate it. thank you. also with us this morning to discuss, a cardiologist, professor of molecular medicine at scripps research. great to have you with us this morning. let's pick up where jeremy left off in terms of potential changes here to that testing window for people coming into the united states. what difference would that make in your mind? >> well, good to be with you, erica and jim. it is nice to get this travel story straightened out. it hasn't been right for the whole pandemic. but it is just one piece of a much important multiprong strategy we need to take on. delta is surging again in this country. no less the omicron story. >> dr. topple, i want to ask and i ask with the proviso we know this is early in terms of data coming in on the threat from omicron. we had a south african health official on cnn this morning who said that so far 90% of those hospitalized in south africa

have been unvaccinated and at least among the young people that they have seen contract this variant of the disease, that they had mild symptoms. it is early. israel is talking about similar data. is this a hopeful sign that omicron may be less threatening than some of the worst predictions early on? >> i think so, jim. i think a hospitalization pattern in south africa or particularly the province that is mostly affected doesn't suggest anything different about this variant, compared to the prior variants of concern. and the original strain. so that's encouraging. there are other pieces of encouraging things to think about because, remember, the beta variant that originated was first detected in south africa, that had a lot of immune evading properties. and ultimately couldn't compete with delta anywhere else around the world. so we don't know about omicron, we know it has lots of mutations, of course. but so far, yes, we have seen

around the world some people who are vaccinated and even with the booster who have gotten infected. those individuals so far have had very mild illness. so-so there aren't the panic s that were felt when this consequence was determined by the south african scientists. >> when we look at delta, you know you pointed out delta is still a real concern. it is the dominant variant in this country as of this morning. and you wrote in the guardian, our problem is not omicron, but using the tools we have which are getting better and better over time. are those tools today in the united states being used effectively and being used by enough people? >> they aren't, erica. you mentioned we -- what we need to tighten up at the borders and the airports. but well beyond that, we have relaxed all of our mitigation measures such as masks and even

using higher quality medical grade masks. we haven't been advocating third shots like we should. this is really a three-dose vaccine. and unless someone had j&j or prior covid. we also, of course, are -- have hit a wall in many respects with getting people -- more people vaccinated. with this delta variant, which is the main problem, so hypercontagious, we have to get 90% of people with immunity wall with the delta, by vaccination or recent confirmed prior covid. we're so far away from that. we're 30% point of the american population. so we had problems in getting the mandates through, even for healthcare workers, because of efforts in the courts. and this is just extraordinary because who would have thought mandates would be necessary to protect people from a serious illness no less spreading it to others. so many things we can do. the other thing to mention is,

the pill that will be not the one that was got a recommendation yesterday, the merck pill, the next one to come is extremely potent against all variants that we have seen. and so that's a welcome addition to our armamentarian. >> thank you for helping us digest all of this. we appreciate it. we should note with the omicron variant raising many new questions. anderson cooper and dr. sanjay gupta will come together with dr. fauci tonight live at 9:00. this morning, we're learning new details about the kind of story that has become so familiar in this country, a shooting at a high school in michigan. this one at oxford high school left at least three students dead, can killed, murdered, in their school, eight others injured. authorities say they believe the suspect fired at least 30 shots, now investigators recovered writings that contain some of

his thoughts during the execution of an overnight search warrant. and there is this chilling video. moments from inside one classroom as students sheltered in place as the shooter tried to lie his way into the classroom. have a listen. >> safe to come out. >> safe to come out. >> no. >> we're not willing to take that risk right now. >> the 15-year-old suspect who is now in custody and on suicide watch, there is a lot to learn about him. students also describing, you see some of the moments on this video, describing what it was like for them leading up to their escape in those moments. >> we heard two gunshots and then after that my teacher ran to the room, locked it, we

barricaded, and then we covered the windows and hid. the very first thing is -- in my head was this is actually happening. i'm going to text my family, say i love them, just in case if i were to die. >> how many kids had to go through that moment, or adults. shimon prokupecz live in michigan. they did uncover some writings from the alleged shooter. what do we know about what they found? >> reporter: so the sheriff just revealing that this morning on "new day." saying that they did find writings, while they were executing a search warrant at his home. and basically just describing it as something that contains the alleged shooter's thoughts. they're hoping that it takes them to a path where they can learn the motive. right now authorities are not speculating on motive, not

giving anything as they're still trying to figure that out. the sheriff also revealing a lot of other new details, certainly that they have now evidence that some 30 shots were fired. they recovered 30 rounds, he said. also very chilling he described seeing video that shows the alleged shooter going through the building, describing it as at close range -- at close range, saying that he came out with intent to kill and calling it a cold-hearted murderous spree, essentially. so there is still a lot for authorities to learn. more and more details are starting to come out now as investigators work through the crime scene and obviously after executing the search warrant at the alleged shooter's home. the big question now is charges. the prosecutor's office said they're not ready to file any charges. they're waiting on the sheriff's office to present them with some of the -- their findings and some of their investigation and once that happens, we will likely see charges. the big question is also is this

15-year-old going to be charged as an adult. that's something else the prosecutors are not commenting on yet. that's something that they are working on. there are still victims. victims that remain in the hospital, one of them, a 14-year-old girl who is on life support, the sheriff yesterday describing her as fighting for her life. we have no update on her condition. but for this community there is still a lot to figure out. and there is still a lot that they have to deal with. >> that is -- >> 14-year-old girl on life support. shimon prokupecz, thank you very much. let's speak about circumstances around this with former acting baltimore police commissioner, cnn law enforcement analyst anthony barksdale. it is just familiar, gutting, these are children. one thing that struck me is the bravery and sort of presence of mind of the students we saw in the video that played a short clip of earlier, they're in their room, it appears the gunman is trying to lie his way into the room, claiming to be a

sheriff, and them saying wait a second, one moment where he says, bro, and the kids say, that's a red flag, bro, that doesn't sound look a sheriff would say. when you look at that reaction, did you think the students there saved lives? >> absolutely. jim and erica, those kids, i feel for them. but they're heroes. if we know what the shooter was up to, they put it together, quickly, and they got out of there. they are heroes. it is a tragedy. but it could have been a lot worse if those kids weren't thinking. but it is also horrible that our kids now go to school, and have to deal with this. it is horrible. >> i have to say that was one of my first thoughts of the active shooter trainings that our kids are now going through, that the

staff is now going through, yes, you're right, it paid off. but what a world we live in, where this is now what our kids have to prepare for when they go to school. i want to ask you about what we learned from the sheriff. the sheriff is saying we can't get a motive from the suspect in custody, but there is a path to a lot of supportive information, noting that, you know, he believes the shooter, quote, came out with an intent to kill. the fact that this suspect is alive, even if he's not cooperating, these writings will be key. >> absolutely. that's really important to note the motive. but i think there are also questions that also must be answered, that are just as important. how did this kid get a hold of a nine millimeter, he's got ammo, he's got additional magazines, how did that happen? so i don't just want to stop -- he's 15 years old. what about the adult that

purchased that gun? what about his father? we have got a lot to look at here. but the motive is important, erica. i agree. >> appreciate you joining us this morning. thank you. just ahead, a consequential day at the supreme court justices set to hear arguments on a mississippi abortion law that could effectively strike down roe v. wade. we are taking you there live. crowds gathering as you can see there outside. plus, an excerpt from a new book reveals former president trump hid a positive covid test from the public. just days before a debate with joe biden. now, he's responding. and before meeting with military families. also ahead, russian president vladimir putin is warning nato allies that deploying troops to ukraine would be a red line for him. the nato secretary-general responding with his own warning and he will join me live in minutes. new neutrogena® rapid firming. a triple-lift serum with pure collagen.

next hour, a crucial hearing as the nation's highest court that could shape the future of abortion rights in america. live pictures here outside the supreme court this morning. the justices will hear the arguments. this is for a mississippi case involving the state's ban on most abortions after 15 weeks of pregnancy. >> we should note and make this clear, this case directly threatens roe v. wade, the current law of the land for nearly 50 years, when it comes to making abortion legal in this country. cnn justice correspondent jessica schneider joins us live from the supreme court. jessica, today's hearing has major implications and to be clear not just in mississippi, but nationally, for folks at home who don't follow the court regularly, can you explain how and why roe v. wade is at stake

with this decision? >> reporter: well, it is at stake, jim, because mississippi is arguing that they want roe v. wade overturned. that is why this abortion case here for the supreme court at 10:00 a.m. is the most consequential inin decades ande difference is the 6-3 conservative court here. we heard from justice clarence thomas who argued in the past that roe v. wade should be overturned. this is a mississippi law passed in 2018, as it has been blocked so far by lower courts. but it basically bans all abortions after 15 weeks with limited exceptions for fetal abnormalities and medical emergencies. this is in direct conflict with the supreme court's precedent in roe v. wade. cases have established the constitutional right to an abortion for women and also that states cannot outright ban abortions prior to viability. that's about 23 to 24 weeks. so the big question here is how will the conservative justices

here who have the clear majority, how will they grapple with roe's precedent? if they do overturn roe, this could have an immediate impact. there are a dozen states that have post roe trigger laws, that means if it is overturned, abortion would be banned in those dozen states immediately. the stakes are high, hundreds of protesters out here in front of the court, just about a half hour away from when the arguments begin. guys? >> jessica schneider with the latest there. as the nation's high court prepares to hear that case, as jessica just laid out, the future of roe v. wade hangs in the balance. former vice president mike pence says he thinks it is only a matter of time before it is overturned. take a listen. >> with the supreme court overturns roe v. wade, and i believe with all my heart that day will come, either now or in the near future, it will not come as a surprise to anyone.

it will simply be the culmination of a 50-year journey whose course and destination has been driven by the will of the american people. >> joining us now to discuss, cnn chief legal analyst jeffrey toobin. there are two things here, right, as we look at both roe and the casey decisions. two of the things that the justices mentioned in each of those were precedent, right, looking to precedent in those cases. and also stressing in the opinions as it was written this real need to follow the rule of law, use constitutional measurement, acknowledging that people may have personal experiences or beliefs, but this needed to be about the law. how do those two, do you think, hold up with the court that we see today? >> well, i think you know, putting the -- your finger on the issue of precedent is very important. because the supreme court cares a great deal about precedent and

cares that it be perceived as a body that follows precedent. except when it doesn't. and that's the problem and that's the issue in this case and so many other major cases, which is the supreme court has the ability to change its precedent. sometimes liberals like when precedents are overturned. liberals very much appreciated when the supreme court said that states could not criminalize homosexual sodomy. that overturned very specifically a decision of only about 20 years earlier. conservatives have been trying for almost 50 years to overturn roe v. wade. and as we have all been pointing out, there are now six conservatives on the bench. it is worth remembering just as mike pence, the former vice president said, you know, in one of the 2016 debates with hillary

clinton, then private citizen donald trump said, if i have appointments to the supreme court, it will be automatic, automatically roe v. wade will be overturned. and i think today is the first real chance for that, in the first real possibility. there is some chance the courts -- the court may try to uphold the law limiting abortion rights in mississippi without saying the words that roe v. wade is overturned, looking for some sort of compromise, but mississippi and many of the outside groups have said there is no middle ground here, you either have to overturn roe v. wade or allow abortion rights to continue, and that has been a bedrock principle of the republican party, overturning roe v. wade, at least since the election of ronald reagan in 1980. >> so what we know specifically about this law, the 5th circuit court of appeals, one of the

most conservative, correct me if i'm wrong there, blocked it saying it violated, right, it violated roe and supreme court precedent. is there anything to read into the path that this law has taken in getting to the supreme court? >> you know, i don't really think there is any -- i don't think there is much to read into it to answer your question. i think, you know, this law is in conflict with roe v. wade, as you said, the core principle of roe v. wade is that states have very limited ability to regulate abortion before viability. viability is you point out is somewhere around 22 to 24 weeks. this is a law that bans abortion after 15 weeks. there is no argument that 15 weeks or 16 weeks is viability. the core of roe v. wade and the casey decision from 1992 is that the state has very different

abilities to regulate abortion before and after viability. viability has been the key determinant in abortion law for 50 years. this mississippi law without question bans abortion before viability. and that's a question that the court is going to have to grapple with today and at least three of the conservatives i think are very likely to uphold the law and want to overturn roe v. wade. that's clarence thomas, as you pointed out earlier, neil gorsuch, and samuel alito. the other conservatives, you have chief justice john roberts who is actually said he wants to support the precedent of roe v. wade, at least in some circumstances, and the two people to keep an eye on today are brett kavanaugh and amy coney barrett, because they have not really talked about abortion since they have been appointed to the court and think they're the most important votes to

watch today. >> and we will be watching, jeffrey toobin, appreciate it, thank you. >> okay. coming up next, i'm going to speak to the nato secretary-general about growing concerns russia could mount another invasion, a full scale invasion of ukraine. his warning for vladimir putin. and just moments away from the opening bell on wall street, as you can see there, three green arrows. nice to see. u.s. futures and global markets higher today following yesterday's losses. a volatile week as investors try to learn more about the new omicron variant. much like all of us. fed chief powell, treasury secretary yellen appearing before the house. the omicron variant poses a threat to the global economic recovery. we'll keep an eye on the markets for you.

secretary of state antony blinken after a meeting with top diplomats said this morning that it is unclear yet whether president -- russian president vladimir putin decided to invade ukraine, but said he does have in place the capacity to do so, on short order, should he decide. growing tensions between russia and ukraine. joining me to discuss, nato secretary-general jens stoltenberg. thank you for taking the time

this morning. >> thank you so much for having me. >> so you heard secretary of state blinken's words there that russia has the capacity to not only invade ukraine militarily, but also destabilize it from within. do you believe that russia plans to use that capacity? >> there is no clarity about intentions by the russian buildup. but what we do know is that over the last weeks, russia has increased the number of troops along the borders with ukraine, and this is an unusual concentration of military force. and we also know that russia has demonstrated that the will to use force against ukraine before, because it did that in 2014 when they invaded crimea and annexed part of ukraine. and also see heightened aggressive rhetoric by russia against ukraine. so we need to be prepared for

the worst, even though we hope for the best. >> you have told reporters in recent days that nato must, quote, send a clear signal to russia about its military activity. you have also said that there would be serious political and economic consequences were russia to invade. what are those consequences? what would nato do if russia crosses the border? >> first of all, we call on russia to not use military force against ukraine once again. we call them to be transparent, to de-escalate, and to reduce tensions. if they decide to once again use military force and invade ukraine, there will be a high price to pay for russia. we have wide range of options, economic sanctions, financial sanctions, political restrictions and also after the

last time, nato implemented the biggest enforcement of our collective defense since the cold war with combat groups in eastern part of the islands and baltic countries and also the black sea region and all the options are on the table. >> are you saying a military response to a russian invasion is on the table? >> i think it is important to distinguish between ukraine, ukraine is a partner, we provide support, training, capacity building, equipment, some military hardware, and that's a part of ukraine. then we have nato allies, like, for instance, romania, bulgaria, other -- poland, the baltic countries, we provide security guarantees. we say that if one of those countries are attacked, the whole alliance will respond -- will come and defend them. this is a difference being a

partner, highly valued partner, ukraine we support them, and nato allies, where we provide security guarantees. >> the trouble is each side has different red lines here, because russia is saying their red line is nato military support to ukraine, including both the possibility of troops, advisers and weapons, and russia warned that if nato crosses that red line, it would threaten gps satellite, saying it has the capability and you saw the test, the anti-satellite test a couple of weeks ago, to take down all 32 gps satellites. i wonder, do you fear that a conflict in ukraine could develop into a larger conflict between russia and nato? >> the task is to prevent that from happening and that's first of all, the reason why we call on russia to stop its aggressive actions against ukraine.

every nation has the right to self-defense. that's enshrined in the u.n. charter and ukraine has been under attack for a long time from russia. invading crimea, but also continuing to support the separatists -- armed separatists in eastern ukraine and now aggressive rhetoric, the cyberattacks and the strong concentration of russian forces close to ukraine's borders. so nato support ukraine is 110%, in line with our national obligations. and nato -- and ukraine has the right to self-defense. and our support to ukraine integrity and certainty. >> what other issue here, right, is what ukraine wants, what nato is willing to give, and how russia would react. because you ukrainian officialse been public about their desire

for a closer association with nato. russia is saying, any closer association with nato, they will not tolerate. what is nato willing to do here? will nato assure russia that ukraine will not become a member state? what does nato say to the ukrainians? what is the answer? >> but just the whole idea that russia can decide what ukraine can do is absolutely wrong. that's actually the idea from the past, where we have -- where we have big powers like russia had a sphere of influence whith controlling small neighbors. ukraine is an independent sovereign nation. they have the right to choose their own path, including whether they will be part of an international security alliance like nato. so russia has no veto, no say on

whether ukraine will become a member of nato or not. that's for ukraine to decide. and the allies to decide when ukraine is ready and meet the nato standards. so, again, russia tries to control neighbors. and that's the main problem in this conflict, that russia doesn't respect the integrity of sovereign independent nation. >> so you're saying to be clear that ukraine either association or membership with nato is still a possibility? >> so we have decided and stated in nato that ukraine will become a member of nato, but ukraine will become a member of nato when allies agree that ukraine meet nato standards. that's for the allies to decide, not for russia to decide. and i myself, i'm coming from a small country, norway, bordering nato. i'm very glad that our nato allies never gave russia that

power over norway to -- we decided to join nato many years ago. >> understood. jens stoltenberg, thank you for joining us. we appreciate you joining the show. >> thank you so much for having me. still ahead, former president trump now refuting reports he hid a covid diagnosis before his debate with joe biden. we have a live report with the latest details next. feel stuck with student loan debt? move to sofi and feel what it's like to get your money right. ♪ ♪

former president trump is now responding to a new report that raises serious questions about the timing of his coronavirus diagnosis. his former chief of staff has said in a new book that trump tested positive days before the white house at the time, the administration revealed that fact to the public. >> and now cnn has learned there were whispers in the white house about trump's positive test before his first debate with now president biden. cnn's gabby orr joining us from washington. gabby, you know, it wasn't just this debate. there were a number of other places along the way where the former president was interacting with people. >> that's right, erica. what we know based on this new reporting is that former president donald trump received a positive test for covid-19 on september 26th. three days later he took the debate stage in cleveland for that first presidential debate

against joe biden on september 29th. and in between that positive test that meadows writes about in his new book, and the first presidential debate he held an indoor press conference at the white house, he held an indoor reception for gold star families at the white house, he held a press conference at the rose garden about coronavirus testing updates, and he met with supporters and held a rally in pennsylvania. so if you add all of those events together that the president -- then president donald trump attended between that positive test and the presidential debate, it is potentially hundreds of people that he knowingly put at risk after receiving a positive test for covid-19. now, the former president did just issue a statement minutes ago in which he denies having tested positive for covid-19 before or during the presidential debate. here's what he said. he said, quote, the story of me having covid prior to or during the first debate is fake news. in fact, a test revealed that i

did not have covid prior to that debate. but as you mentioned, there have been whispers inside the trump white house about this test, and according to the guardian's reporting on this excerpt from mark meadows new book, he said to proceed as everything is normal after the president received that positive test. >> proceed as though everything is normal. you know, you think you can't be shocked anymore and then sometimes you are. gabby orr, appreciate it, thank you. >> put other people at risk. put other people at risk. yeah. >> yeah. well, up next, it is the congressional version of mean girls. republican women publicly name calling, calling each other trash, grifter, so where is party leadership in all of this? call the principal.

very public infighting among the house gop. at the center of the exchange, representative nancy mace who criticized lauren boebert for making anti muslim comments about democratic congresswoman ilhan omar and others. in response, congresswoman marjorie taylor greene tweeted in part nancy mace is the trash, her words, in the gop conference. mace, you can back up off of lauren boebert or go hang with your real gal pals, the jihad squad. so mace responded this way saying -- >> make no mistake. marjorie taylor greene is a liar. she's crazy, she's insane. she's bad for the party.

>> well, greene, of course, returned fire tweeted she had spoken with trump about mace, responded saying this is about greene's anti muslim rhetoric. >> what it says to me is if you say something that's bat shit crazy, you're going to raise money. that's the only reason she does that. she's a grifter of the first order and she does that to raise money. >> cnn's melanie zen known nah joining us from capitol hill. nobody said congress was neat and polite, not sure you thought you'd be spending your days this way. how is, if at all, minority leader kevin mccarthy handling this public feud? it was a little quiet in the beginning when it was dealing with boebert and her comments about ilhan omar. where do you stand this morning. >> reporter: kevin mccarthy is working behind the scenes. he knows this is a huge

distraction for republicans. they would rather keep the focus on the biden agenda. the head of the gop arm said we should not be the headline here. let's stay focused on our goals. as manu raju and i reported yesterday, kevin mccarthy hauled in greene and mace for private meetings where he told them to knock it off. after the meeting i caught up with greene who said she would support a primary challenge to mace. and mace said, all i want to say about marjorie taylor greene is bless her effing heart. democrats say this behavior from the extremists in the party like lauren boebert is completely unacceptable. take a listen to what ilhan omar had to say yesterday at a press conference about boebert. >> when a sitting member, a

colleague a member of the jihad squad and falsifies a story to suggest that i will blow up the capitol, it is not just attack on me, but on millions of american muslims across this country. >> reporter: what's unclear at this point is whether democrats will actually try to punish lauren boebert. so far, however, most of them are saying the onus should be on kevin mccarthy. jim, erica. >> we'll see what appetite he has to try to stop it. melanie, thanks very much. right now, hundreds of people are gathered outside the supreme court as justices are set to hear arguments on a case that could aend abortion rights for many parts of the country. we'll take you there live next.
