there it is. "violence@nbcge.com." >> allison should know. >> what is internet anyway? what, do you write to it like mail? >> no. a lot of people use it and communicate. i guess they can communicate with nbc writers and producers. allison, can you explain what internet is? hello and welcome to all you watching here in the united states, canada, and all around the world. i'm kim brunhuber. on "cnn newsroom," ukrainians raise their voices in unison as world leaders turn to diplomacy to end a standoff with later russia. we have reports from moscow and ukraine. police in canada move in on protesters to clear the blockade on north america's busiest international crossing. we look at whether it's working. and we're just hours away

from kickoff to super bowl lvi with law enforcement bracing for massive crowds . more countries around the world are urging their citizens to leave ukraine as the threat of a russian invasion seems to grow by the hour. the u.s. is among nations drawing down embassy staff in kyiv. the u.s. says poland will allow americans to cross over from ukraine without advance approval. dozens of governments are tell their citizens to get out. others have issued travel advisories not to enter ukraine. the ukrainian government says it's an overreaction, creating a sense of panic that only benefits moscow. >> we are on these borders. it's our borders, it's our territory. we have different information. and now the best friend for

enemies, that is panic in our country. and all this information that tells only for panic doesn't help us. >> cnn's sam kylie is live in eastern ukraine. we'll have reporting from nic robertson in moscow later this hour. arlette saenz at the white house and saturday's call between presidents biden and putin. >> reporter: the white house says there was no major breakthrough in that one-hour call between president biden and russian president vladimir putin. a senior administration warned there is still a distinct possibility russia moves forward with an invasion of ukraine. the president spoke with putin while spending the weekend at the presidential retreat at camp david. and the white house in a statement reading out the call said, the president warned of severe and swift costs that russia would face if it moves forward with an invasion of

ukraine. the white house also said president biden reiterated a further russian invasion of ukraine would produce widespread human suffering and diminish russia's standing. president biden was clear with president putin that while the united states remains prepared to engage in diplomacy in full coordination with our allies and partners we are equally prepared for other scenarios. the u.s. has crafted sanctions with its allies to implement should putin move forward with an invasion of ukraine and the u.s. has also reiterated its commitment to offer defense support to ukraine so the country would have means to defend itself in the event of an invasion. now the u.s. at this moment says that they do not believe president putin has made that final decision to invade ukraine, but they also note that what they are seeing on the ground in the area does not tend to show de-escalation, which is what the u.s. is seeking in this

moment. the u.s. over the course the weekend has drawn down its embassy presence, evacuating most nonemergency personnel from the embassy in kyiv. they are also warning americans to depart the country immediately, saying it is pastime for americans to get out of ukraine. the u.s. is warning that they will not be conducted an american military mission to evacuate american citizens if an invasion occurs. going forward, president biden and his team plan to remain in contact with russia in the coming days as the threat of an invasion looms. but officials are warning that they also believe while they are conducting, while they are trying to stay in contact with russia, it is still very possible that putin moves forward with an attack. >> for more on the situation on the ground in ukraine, we're joined by cnn's sam kiley in the city of harkiv near the russian

border. what's been the reaction to the flurry of diplomacy that doesn't seem to have borne fruit so far? >> reporter: not borne any fruit, as you were saying in your introduction there has been a flurry of international organizations. above all, foreign nations withdrawing or downsizing their size of their embassies in kyiv, moving their embassies from kyiv to laviv in the far west close to the polish border. in the case of the united states and britain also announcing that they're both going to be withdrawing the training teams that have been working alongside the ukrainian armed forces to try to bring them up to nato standards, also to teach them how to use the recently supplied javelin and shoulder-launched anti-armor weapons. there's 160 americans from the national guard being withdrawn, about 100 britons being withdrawn over this weekend.

and that is to make sure that there are no nato boot footprints on the ground should the russians invade, because of course that would greatly complicate matters in terms of how nato were to react. but here on the ground just 30 miles from the russian border, kim, we know from satellite imagery, from reports from the united states, and indeed from press releases from the russian armed forces, that there is a massive force gathering just across the border to the north here some 40 or 50 miles in land beyond the border, potentially threatening to overrun this city of 1.5 million people, which is sid 75% russian-speaking. there may have been an assumption in the kremlin they might receive positive reception having russian tongue. having been here talking to people on the ground, there is no love lost for the ambitions of the kremlin. there is a great deal of sense

of brotherhood and cultural affinity to fellow russian speakers on the other side of the border, but there is a resolute attitude here that the ukrainians will fight. how long they could fight in the face of a russian blitzkrieg, effectively, is very much in doubt with the number of international military analysts suggesting kyiv, the capital, could fall within a few days. in the case of kharkiv, little effort in efforts being made to protect the city. the assumption and the hope has to be diplomacy, hope against hope, diplomacy will somehow win through. >> sam, we've seen demonstrations of solidarity in kyiv. is there any sense that they could grow? >> reporter: there have been demonstrations of solidarity. a week before the one in kyiv, i attended one here in kharkiv. the demonstrations are important here because they did and they

were intended to bring together particularly those russian-speaking elements, but also elements of the far-right right through to people from the far-left and cultural-left, if you like. often in the past there have been clashes between those different groups here in kharkiv, but the demonstrations are all intended to try and send a signal. i have to say they're relatively small in size, as are the numbers of people i've seen training with citizens, militias, home guard units, reservists that have not yet been called up. that may indicate also that the government here is continuing to try to downplay this idea that an invasion is imminent. as the president says here, if the panic serves only the interests of ukraine's enemies, and by that in this context, he means in the kremlin. >> sam, looking at the bigger picture here, we heard american officials talking about what the

consequences of an invasion would be. not just on ukraine, obviously, but how it would have implications for other regions as well. walk us through what those might be. >> reporter: if you had a russian invasion, an unprovoked invasion that is an invasion caused by a desire to prevent, technically speaking, publicly the motivation would be to try to prevent nato getting a foothold here in ukraine. now ukraine can't join nato while it hastert that is disputed. so that means the illegal seizure of the crimean peninsula would prevent, ultimately, until that issue was resolved, ukraine joining nato. but what that would also mean is a russian invasion here would bring the front line, if you like, of russian influence right up against the borders with poland, the baltics, very close to the baltic states, romania. it would fulfill, to some extent, the kremlin's stated ambition, to return the european

security architecture to pre-1997 when so many formerly eastern bloc countries joined the european union, joined nato, and became part of that western democratic bloc. and it's that western democratic bloc i think that ultimately is the existential threat seen by vladimir putin and ultimately covertly, in a sense, his motivation for invading ukraine. it would also mean that the international rules-based order is ripped up by at least a former superpower, a nuclear power, would demonstrate that it is possible without a great deal of severe military consequence to invade a neighbor in an unprovoked, nondefensive action. something that would be catastrophic in terms of the signals it would send, the basis upon which certainly since the cold war but even during the cold war, international relations have been conducted. it would mean that china would take a look at what was going on

and think, well, maybe we'll go into taiwan. other countries with territorial disputes and claims on territories elsewhere might feel emboldened to send their tanks across those separation lines. it would be ultimately catastrophic. >> yeah, so much at stake as you say. appreciate the reporting, sam kiley in ukraine. you're looking at scenes from early saturday morning in windsor, canada, as police began to clear a blockade at the ambassador bridge on the u.s./canada border. what began as a handful of truckers protesting vaccine mandates has become a broader movement of canadians unhappy with current restrictions. >> ending all mandates. you know, it's been two years of this stuff. evidently it's not working. we all need to get back to normal. >> our freedom's at stake and they're treating us like something we're not, basically.

trying to do our part. we understand the economy's come to a halt. >> several border blockades across canada have taken a toll on the economies of both countries. prime minister justin trudeau and other officials are discussing additional measures to break up the protests. cnn's lucy ckavanaugh has more from wind door. >> reporter: you can see the ambassador bridge behind me that critical, vital link between the u.s. and canada. the bridge remains closed but the crowd is significantly thinner since the early hours on saturday. that's when we saw a heavier police presence. they sort of pushed back the protest line a little bit. a lot of protesters leaving on their own. there's a lot fewer trucks and cars blocking that area. in terms of the crowd, it's been a lot of families, a lot of people milling about. you hear the occasional honks like you're hearing right now. shouts of "freedom." there's been young kids and families, some religious minority groups, walking back

and forth with protest signs. a lot of frustration towards the vaccine mandates, but also towards the government of canada. so a lot of different people joining these protests, but again, the steam at least here in windsor seeming to thin out. that's in part due to the harsher restrictions that have been imposed. things like up to $100,000 fines, penalties for protesters, a potential year in prison. that may have had an impact in getting some folks to go home. but for now, the stale nmate remains. l l lucy kavanagh, windsor, canada. those protests are inspiring similar action in france where police used tear gas to break up demonstrations. the so-called freedom convoy descended on paris and blocked traffic at various locations. over 7,000 police were deployed in advance of the convoy's

arrival. in the u.s., republican senator rand paul says he's all for trucker blockades similar to the protests in canada, and he hopes they clog up major u.s. cities and disrupt the super bowl. >> i'm all for it. civil disobedience is a time-honored tradition in our country, from slavery to civil rights to you name it. peaceful protest, clog things up. make people think about the mandates. >> opponents say it would harm the economy even more. congresswoman debbie dingell represents michigan, which has already been greatly impacted by the protests. here's what she told cnn. >> i don't believe that people have the right to block a major economic trade route between two countries that is impacting workers in very realtime. i think we really need to look at who is encouraging these protests. it's not the truckers, it's

the -- independent truckers, canadian truckers have said they're not supporting this. >> law enforcement officials across the u.s. and near the site of the super bowl in california are already on high alert. they've been warned by bhs a convoy of truckers could pop up at any moment. still ahead, we'll go to beijing where all eyes are on the doping scandal, overshadowing a much-loved olympic sport. details on the hearing that will determine the if the 15-year-old russian athlete can compete. americans are being pulled in two directions on covid mask mandates. how more states are charting their own pandemic course, leaving the cdc guidelines behind. detergent alone, can't. - i think wewe should explore a few solutions?

to the beijing where the olympic fate of a 15-year-old russian athlete is still up in the air at the winter games. the hearing just a few hours from now set to determine whether figure skater kamila valiyeva will be allowed to

continue to compete. she was crucial in the russian olympic committee's gold medal win in monday's team event. that medal ceremony has been put on hold until the controversy is resolved. officials say a decision should be made by monday afternoon. "world sport's" patrick snell live from atlanta, cnn's steven jung in beijing. on the doping controversy we're in a waiting pattern. bring us up to speed on what's been happening in the meantime on this story. >> reporter: kim, the latest we have learned is valiyeva has been named on the draw for that tuesday figure skating event, that she is scheduled to appear next. that's why all eyes are on this virtual hearing taking place in about four hours by the court of arbitration for sport. and that decision by them monday afternoon obviously going to be ahead of that tuesday event. that decision is really going to determine whether or not she will go ahead to attend it. the international olympic committee, in the meantime, has

still not been saying much about this because of this ongoing process and legal ramifications. a complicating factor here is that positive test sample was collected on december 25th, before the olympics. that's why the ioc actually does not have jurisdiction over this. now the russians, of course, the russian sports authorities, including its sports minister and the head of its figure skating federation, they have been throwing growing support behind valiyeva with the sports minister saying he's been talking to her in the past few days and he has no doubts over the honesty of her and also the strength and the energy and the optimism he has heard from her voice has further convinced him of her innocence. the russians, of course, have been saying she's been testing negative both before and after that collection date, including here in china since she arrived here. that's why, again, they are -- they have lifted that temporary ban placed on her.

and another thing they've been saying is the circumstances surrounding the test results, saying how unusually long it took the lab in sweden to analyze the samples. all of this undoubtedly will be raised during the hearing. that's why a lot of people e eagerly await that decision, including here in a very snowy beijing. >> absolutely. we'll stay on top of that story. thank you so much. let's go to patrick snell. steven raised it, snow, right? it had a huge impact on many of the events today. >> yeah, you're right, kim. steven just mentioning it. really one of the big stories of the day so far on this sunday is that adverse weather giving us these headlines and the ongoing impact it's been having on the scheduling over there. the chinese capital, beijing, look at this, coated in real snow for the very first time during these games as they try and shovel it away there. heavy snow also seen in and around the genting snow park where the women's free ski slope

style qualifiers were supposed to take place sunday morning. the poor weather forcing that to be rescheduled to monday morning. the big name there to watch out for, eileen guve, the chinese-born american competitor who's already won gold. the men's qualification will take place tuesday. the men's finals we understand will be concluding on wednesday. you can see the knock-on effect that's kicking in already. the international ski federation saying the decision made due to the heavy snow and the poor visibility. we can tell you that heavy snowfall also delaying the second run of the men's giant slalom. delay of at least 75 minutes there as plows and personnel were working to clear snow off the course. in fact, i can tell you now within the last few minutes, in fact, that the swiss competitor, the swiss great, the favorite going into this, marco odermatt,

has sealed victory. he was the favorite, and he gets the job done within the last few minutes, sealing victory in the men's giant slalom on sunday. >> patrick, this is an interesting story. an american bobsledding star trying to win gold at a brand-new olympic event. take us through that story. >> yeah, this is one we've been following very closely indeed. fair to say i think a very challenging start indeed to these winter games for the american bobsledder, elana meyers taylor. the californian was supposed to help carry the u.s. flag at the opening ceremony, but what happened? testing positive for covid-19. and this just two days after arriving in china. the 37-year-old, who won two silvers and a bronze at a previous olympics, able to compete, though, after being released from isolation. and earlier, taylor going in the women's-only monobob event. this is making its olympic debut. and she's in fourth place right now, i can tell you after the

first two runs. we got runs three and four on monday there in beijing. but there is so much more to her story. it's a really powerful one. elaina was one of the few athletes who was allowed to bring her child to the games. 2-year-old nico, born deaf in both ears, was diagnosed with down syndrome. she says raising nico is much better than any medal she can win. >> being nico's mom is the biggest achievement of my life. he is such a ray of sunshine, a ball of joy. i can't imagine life without him, and i can't believe i competed this long without him. because he just brings so much more passion to my sport, believe it or not. because i know that every day i go out there, i want to show him that it's possible to go after your dreams, it's possible to go after your goals. more so now than ever, i'm doing this for a greater purpose. >> elana's words very, very powerful indeed. with that, i'll send it right

back to you. >> what a great story, patrick snell, thanks so much. french and u.s. leaders again try to talk russia out of invading ukraine after investing in a massive military buildup. is the kremlin even listening? we'll have reaction from moscow after the break. no problem, the sleep number 360 smart bed is temperaturure balancing so you both sleep just r righ. and it senses yoyour movements and automatically adjusts to keep p you both effortlessly comfortable. so, you can really promise bebetter sleep? yeyes! you'll know exactly how well you slept, night after night. we take care of the science. all you have to do is sleep. don't miss our weekend special. save 50% on the sleep number 360 limited edition smart bed. plus, 0% interest for 24 months and free premium delivery when you add a base. ends monday. migraine attacks? qulipta™ can help prevent migraine attacks. it can't prevent triggers, like your next period or stress. you can't prevent what's going on outside, that's why qulipta™ hel. qulipta™ is a pill. gets right to work to prevent migraine attacks and keeps them away over time.

watching here in the united states, canada, and around the world. i'm kim brunhuber. this is "cnn newsroom." threat of a russian invasion in ukraine has been building for months but the u.s. and its allies fear it could happen very soon as diplomacy stalls. many countries have advised

their citizens to leave ukraine and the u.s. is one of a number of nations drawing down its embassy staff in kyiv. cnn's nic robertson is in moscow with the latest appeals to the kremlin to de-escalate. >> reporter: from any of these three big phone calls today, president biden, president putin. president pute ton, president macron. sergey lavrov, the russian foreign minister, and secretary of state antony blinken. hard to see any real advancement. the kremlin's readout from the phone call from president biden, that it was coming from a position of hysteria about this supposed russian invasion of ukraine. the russians pushing back as well to what secretary of state antony blinken said on that particular issue, saying that this is really sort of a propaganda position, that this is allowing the ukrainians the opportunity to try to start a war in ukraine, start it with the pro-russian, russian-backed

separatists in the east of the country. so in all these diplomatic phone calls talking past each other, it seems to be the case, and the kremlin in all of these calls as well making the point that they haven't had their core issues addressed. those core issues being denying ukraine to be able to have membership of nato, and nato to go back to its 1997 lines and membership positions. so the kremlin just staying in their current position. i think one takeaway certainly from the phone call with president macron and the phone call that secretary of state antony blinken had as well, both trying to sort of get russia to commit to a track of diplomacy. but by saying to get to that track, de-escalate the forces around ukraine. show that you're committed to moving forward with diplomacy. that's the way to go. really trying to just test and see if russia does actually have an intention to try to talk this through or are they really just building up their forces as a

threat, and then as the u.s. assesses, they say putin hasn't made a decision, but as the u.s. assesses, increasingly looking likely the possibility of a russian invasion. very hard to make a determinant, president putin not conceding any ground or developing a new position at all. nic robertson, cnn, moscow. have a look at this. colorful lights, floats, dancers parade the streets of southern france. they're loudly celebrating the return of the nice carnival. the carnival canceled last year due to covid, opened friday, roaring the theme "king of the animals." relaxation of some health restrictions in france, organizers of the event hope to see 5,000 people and welcome 7,000 standing spectators. attendees are mandated to wear face masks and carry proof of vaccination according to local news reports. the carnival is open for 15

days, closing february 27th. new scrutiny of federal u.s. covid guidance as more states move forward with lifting mask mandates. new infections are declining across the country as the omicron wave subsides. that crop drop has led to states relaxing measures towards a new normal. this even though the centers for disease control and prevention hasn't changed its guidelines. the agency recommends all americans wear a mask in areas of high or substantial transmission, which is the vast majority of counties nationwide. cnn's polo sandoval has the latest. >> reporter: from coast to coast, governors are rolling back their mask mandate according to a cnn analysis. only these six states, as well as puerto rico and washington, d.c., still have such a requirement in place. however, california, illinois, and oregon already announcing plans to lift that requirement in the coming weeks. that leaves only hawaii, new mexico, washington state, puerto

rico, and d.c. with no announcement on when they'll end their mask mandate. then there's masking up in the classroom. school systems in these eight states have either moved toward ending mask requirements or expected to do so by the end of march. however, local governments and school districts are still free to keep making masks a must even after state requirements are lifted. >> this is really a decision for elected officials, and they've made the decision to remove this. which is their right. what i would like to see is to make it easier for individuals to protect themselves. so what does that mean? that means basically making high-quality in facts like n95 masks as widely available as toilet paper and soap and water are in every facility. >> reporter: governors in states scaling back have pointed to an improvement in covid metrics when making their decision. that includes lower infection rates and covid hospitalization numbers that are dropping. some doctors worry the centers for disease control and prevention could be falling behind. >> right now we've got the state

saying one thing, the cdc saying they're looking at this again. that's just not enough. >> reporter: dr. ali raja, massachusetts general hospital, urging the cdc to issue revised masking guidance to help improve confidence in that agency. >> my patients every day say, i'm hearing this from the federal health agencies, i'm hearing this from the local town health agencies, i don't know what to do. and the confusion between what we're hearing on the federal level and what states around the country are doing is just damaging to the trust and the psyche that the population has in our health officials. >> reporter: also losing the masks, amazon. this week the company announced fully vaccinated warehouse workers can go maskless in states that have eased off indoor mask wearing. the new policy does not apply to the unvaccinated or those working in the few states where masking indoors remains in place, for now. polo sandoval, cnn, new york. >> joining us is dr. karan,

stanford's department of infectious diseases and graphic medicine. as we've seen, local and state covid restrictions are being dismantled while the cdc is saying it's still too soon. the fact that we're seeing such a disconnect between local authorities and federal health authorities, does that indicate all of this is more about politics than good health policy? >> i do think a lot of this is being dictated by politics to this point. if you look at the public health response, one of the most important things is to have a unified response. we can't have 50 separate responses, different communications, different messaging. the biggest problem is the incidence is very high. hundreds of thousands of new cases. when you pull back on restrictions at a time like this, really not restrictions but protections for people, you run the risk of having another large surge. >> many jurisdictions have already announced sort of ahead

of time, by this date we're going to drop mask mandates, so on. a week, ten days, whatever it is. when you're looking when to end these restrictions or protections, as you just say, you've argued we should use data, not dates. explain what you mean, what you think the benchmarks should be. >> absolutely. i worked in a state health response for over eight months in massachusetts during our first surges in 2020. when the epidemic is well controlled i would say our test positivity rate is below 2%, closer to 1%. in california, for instance that number was closer to 8% this week. and that's just far too high. we're dealing with a more transmissible variant now. i think a lot of people are kind of discounting the potential harms that are associated with infection alone. it's been now over a year and we're starting to get some of the results back showing that long covid is a problem.

as well issues once you've gotten infected and you've recovered. i realize this is going to be a problem. >> yeah, and then there's also the fact that studies are showing that booster protection wanes after some four months. how does that factor into this decision as well? >> absolutely. we've always said that it can't be a vaccine-only strategy, it has to be vaccines-plus. testing, better ventilation, better masks, protective measures to slow down spread. when you are only relying on vaccines or heavily relying on vaccines, people will get confused with the messaging, particularly because some folks, especially those who are anti-vaccination, say i thought the vaccines worked, looks like they're not working. rather than understanding that the science of the virus and of the complex immune system is one that is constantly shifting, and we have to adjust our public health strategies accordingly. >> so one of the debates in that

public health strategy is around vaccine mandates, other countries as well, whether to expand the definition to include the booster or the third shot. in fact, some experts are arguing either you should say that you have to have that three-dose vaccine series to be fully vaccinated or you just scrap the vaccine mandate altogether. what do you think about that? >> i think it's tough to make absolute calls on these things because if you've been infected, for instance, and you've been vaccinated with two doses, we know that people that have had that combination also have a robust immune response as well. so i do think that we need to sort of think about the complexities associated with mandates. with that said, i do think that the more people that are vaccinated, and especially people that are going to be working with others who are immunocompromised, such as in the health care sector, there i think vaccine mandates make a lot of sense. obviously there will be exceptions. we need to continue to work with people who may have questions or concerns regarding the vaccines. but what we do know is that

vaccines do reduce transmission. they definitely do reduce severe disease and death. this is important. as we sort of move forward, building up trust in vaccines is an ongoing challenge in public health. >> so finally, for the last 30 seconds we have here, i know you're for keeping many of the protections in place. but right now, are there a few of them that you think could be dropped safely? >> one thing i'll say is clinically, as i took care of patients the last two years, we've realized a lot of our patients who are very sick and in inflammatory phase, many who are near the end of life, may not be transmitting the virus as much as those who are much earlier in the course. so for those patients, you know, if we can get the testing done for them to show they have very low to no viral load, then families should be able to visit these patients and relatives of theirs. if there's any concern, those family members can wear n95 masks. i do think it's very important

that we allow family members to get closer to their loved ones, especially when they're near the end of life. >> so many families have been haunted by the fact that they haven't been able to have that last chance to say good-bye. so that definitely makes sense. dr. karan, thank you so much for your perspective. still ahead, some say nicaragua's government is putting higher education in the crosshairs. we'll explain after the break.

if i go to sleep right now, i can get more.... four hours. that's not good. what is time? time. time is just a construct. construct. construction. there is a crack. oh god are you kidding me?! oh god... hi, aren't you tired of this? -yes! good days start with good nights.

seems like a good time to find out about both. why are you talking like that? is this an ad? are we in an ad?

in nug raug wa, president ortega's government is taking aim at higher education, shutting down several colleges and universities. the government says schools broke the law. critics say it's the latest example that shows ortega tightening his grip on power. cnn's rafael romo reports. >> reporter: political rivals

and opposition activists were targeted first. protesting students were next. soon not even those who at one point were political allies and comrades in arms were safe. and now the government of nicaraguan president ortega is cracking down on colleges and universities. >> it is the succeed time the nicaraguan government has prevented me from finishing my university studies. they tried to expel me in 2013. now they're closing the university where i went to study. >> reporter: he says he had to flee the country because he was without options for higher education after he was expelled for participating in the 2018 anti-government protests. earlier this month the rubber stamp national assembly effectively shut down at least 12 colleges and universities. authorities say the government will soon reopen them, but the institution will now be under the control of government officials. the national assembly passed a law allowing the state to take over at least six of the

universities. a anynicaraguan government repo accuses them of not filing financial reports as required by law, as well as changing administrators without notifying authorities. a quality higher education is our main commitment, as well as stability and lowering tuition, this education government official said on a state tv channel. >> anythinicaragua is a country occupied by its own police forces. >> reporter: critics like ernesto medina, a former president of nicaraguan's american university, say this is another example of repressive regime trying to silence any remnants of dissent. >> no public demonstrations are allowed. the independent press has been almost completely silenced. many journalists are in jail or forced to go in exile. >> reporter: rivera, the former

student, says he's not the only one who felt it was time to leave nicaragua, because he was afraid he would end up in jail or worse for participating in protests. >> no less than 50 students are in my situation because they are activists and human right defenders who disagreed with the violence of the government against civil population in nicaragua. >> caller: ortega, who's ruled nicaragua since 2007, was re-elected to a fifth term in november in an election called a parody by the government of canada and a pantomime by u.s. president joe biden. last year, ahead of the election, dozens of opposition leaders, including seven would-be presidential card candidates, were detained by his forces, clearing the way for ortega's victory. >> and we'll be right back. ysolr kills 9999.9% of bacteria detergent alone, can't.

as tens of thousands of fans gathered at sofi stadium for the big game, security is a top priority. cnn looks at the multiple agencies tasked with protecting the biggest game in sports. >> reporter: this is a dream come true for so many fans here in l.a. and also for the many businesses around the area, especially the ones that have had a very hard time during the pandemic. but it is not going to be easy for law enforcement because we're talking about almost 100,000 people that are expected here for the super bowl. and the federal government has been working with local law enforcement agencies for about a year now to make sure that things run smoothly. we're expecting hundreds and possibly thousands of men and women in law enforcement to both on the ground and in the air, one of the things they'll be looking at is traffic patterns. especially because we know there is that possibility of these trucker protests here in los angeles. the government also saying that this is, of course, a target for

terrorism. but they say that at the moment, there are no credible threats. they feel like they have everything under control for this super bowl weekend. now on a much, much lighter note, this could be a regard-breaking weekend when it comes to the weather. so many may not be prepared for those high temperatures. the highest temperature ever recorded during a super bowl game, 84 degrees. and that was almost 50 years ago, a game also played here in los angeles. we're expecting high temperatures as well for super bowl day. no matter who wins or loses, we expect l.a. to break that record in terms of the heat. camilla bernal, cnn, los angeles. as camilla mentioned, heat could be a big factor in the game. los angeles is currently under heat advisory. game-day temperatures will be in the mid-80s. let's bring in meteorologist tyler mauldin. are people going to be suffering there? >> yeah, it's feeling more hike

springtime in southern california. we have 20 million people under this heat advisory, which will last through the 6:00 p.m. local time this evening. that's from los angeles, riverside, all the way through oceanside, san diego. we've been breaking records the last several days. on saturday, some of us topped out at 90 degrees in southern california, beating previous daily records that have been around, some nearly 50 years. as mentioned, the hottest super bowl on record, 84 degrees. we could possibly tie or break that. we're certainly, we're confident we're going to have a top five warmest super bowl later on this afternoon, this evening. because by the time we get to kickoff, temperatures will be in the low 80s. this is going to be a top five event for us on this super bowl sunday. mind you, though, it is winter. so when we expand the view here, you can see frigid air spilling down out of canada into the midwest, where we have windchill warnings in effect this morning.

some of us will be waking up to temperatures minus 35 windchills. around minus 35, minus 40. and then from i would say north carolina, the virginias, into new england, we could see a winter storm bring some snowfall to the region on sunday. we have winter weather advisories from the virginias into new jersey. this includes washington, d.c. and eventually boston will be included in that later on this afternoon. >> better a hot super bowl than a snow bowl, i guess. tyler mauldin, thanks so much. a dolphin at one florida aquarium is making a splash with this super bowl prediction, tapping the salesman bengals to win. nick, a rescued bottle nose dolphin, chose between two signs on his aquarium window. it could be a good sign for bengals fans since nick has gotten 7 of his last 9 predictions correct.

the huge roar of a crowd, it's something you might see at a football game or rock concert, not a golf course. here's why they went so crazy. pga tour golfer sam ryder teeing up in front of a massive crowd at the phoenix open saturday. the ball bounced onto the green, right into the hole. ryder can't believe it, he's jumping up and down. the thousands of fans watched, the stands going crazy, throwing beer cans into the air, cups onto the course. it's a moment ryder won't soon forget. i'm kyle brunhuber. i'll be back in just a moment with more "cnn newsroom." please do stay with us.
