life. the michigan school district where four students were shot and killed are now requesting an independent investigation. >> we want to know if there was any kind of warning or threat. that did not happen. the omicron variant rise in cases and deaths. >> we need to mobilize together to do the things we know work. >> reporter: representative ilhan omar says she's certain that republican lauren boebert will face punishment for her remarks. >> this kind of behavior cannot be condoned. >> i'm phil mattingly in washington. pamela brown has the day off. you are in the cnn newsroom. tonight a nation honors long-time senator and gop presidential nominee bob dole who died this morning at the age of 98. his american journey took him from the plains of kansas to world war ii europe to capitol hill where he became one of the most powerful politicians of the 20th century. in a statement, president biden remembered dole as, quote, an american statesman like few in our history. a war hero and among the greatest of the greatest generation, and to me he was also a friend whom i could look to for trusted guidance or humorous line at just the right moment to settle frayed nerves. i will miss my friend. president george w. bush said, quote, i will always remember to salute him at the capitol. cnn's wolf blitzer looks back at that life and legacy of bob dole. >> bob dole was the kind of politician you'll have a hard time finding in washington these days. much of the country only saw the cartoon image hatchet man. >> senator bob dole has earned his reputation as a hatchet man tonight. pundits who didn't know better labeled him mean-spirited but the man wasn't defined by grouchiness or gridlock. in the senate where he spent the bulk of his political life, dole became a master at forging compromise, working with democrats to cobble together bills that left the country better off. a food stamp bill with george mcgovern, the americans with disabilities act with tom harken. >> some may find it odd that congress was my life. but that's not so. with all due respect to congress, america was my life. >> reporter: he was also the driving force behind the magnificent world war ii memorial. >> i became the official greeter. i tried to greet every group. i can't explain the emotion and what it means to these 95-year-old veterans who get a chance to touch and feel the world war ii memorial. it's part of the best thing that's happened to them in years and they're going to remember it the rest of their lives. >> reporter: dole was one of those young americans who went off to war . on a hillside in italy, a bomb severely injured his spine. he spent the rest of his life in a wheelchair. >> i would look next to me and there was somebody whose leg was shot off. i didn't feel so sorry for myself. >> reporter: voters in his home state of kansas sent dole to washington for five terms where he thrived, becoming a republican leader in the senate. he was president gerald ford's running mate in 1976 and ran for president in 1980 and 1988, finally winning the republican nomination in 1996. >> william jefferson clinton has a job for four more years. >> it didn't work out. >> it was a lot more fun winning. it hurts to lose an election, but stay involved and keep fighting the good fight. >> a 45-year political career was over. dole moved on with grace. after the bitter 2016 primaries, dole was the only former republican presidential nominee to attend the convention that nominated donald trump. he poignantly sa saluted the casket of fellow republican but frequent rival george bush. to the end dole kept the trademark humor so familiar to those who knew him, and so surprising to those who did not. >> we always tried to have a little fun. in my view, if it's not any fun, it's not worth doing. you look at your life on reflection, and i think success and failure are not opposites, i it's just part of your life. >> wolf mention the the world war ii memorial. there were no shortage of weekends in washington, d.c. when you could go to that memorial and see former senator bob dole there to meet with honor flight participants or world war ii veterans who came to visit. he didn't tell them his stories, he was just there to listen. he was a great guy who cared about the country. the flags are half staff at the white house right now on the order of president biden and that's where president biden just wrapped up a speech at the kennedy honors ceremony. he recognized others like bette midler. george, what did you hear tonight? >> reporter: there's been a whole range of emotions at the white house all day long, especially as it began with the death of bob dole, who was so close to the president, and we moved to the kennedy center honors event, the reception here at the white house, and this is returning to a tradition that got broken up or interrupted due to the fact that president trump did not hold the reception during his years. in the last year, of course, the situation was interrupted due to covid. so all of that changes today as we return to this reception here at the white house. as you said, a number of well-known entertainers including bette midler, lauren michaels, probably the funniest event in the white house at this briefing, simply because president biden is one of those individuals that "saturday night live," produced by lauren michaels, has not quite yet been able to truly capture with one character. they tried it again and again and again. the president weighed in on that in this reception. listen. >> he's trying out seven guys to play me. as we say in our father, bless me, father. if you can't laugh at yourself, you're in real trouble, and you make me laugh at myself a lot. >> do you want me to play you? >> steve, i'm afraid you understand me too well. >> steve martin there, if you didn't already know, who also played on "saturday night live" a bunch of times offering to play the president. we'll see what happens in the future on that. meanwhile, as you said, phil, this is going tib very big week for president biden, another very big week. it's going to begin on monday with a speech from the president discussing his build back better plan and how it is targeted in order to help seniors pay their bills for prescription drugs. but probably the hallmark of the entire week is going to be on tuesday when the president gets on that secure telephone call with russian president vladimir putin. number one, the top item to be discussed, of course, is the thousands and thousands of russian troops massing on the ukraine border. it's not clear to u.s. intelligence what the purpose of that is, whether, for example, mr. putin is thinking about invading ukraine once again or if this is some kind of a bluff. so they're going to try to get to the bottom of that. bottom line, of course, on ukraine is if putin invades sometime next year, then this administration is suggesting they will move forward with some severe economic sanctions. phil, back to you. >> joe, a lot of concern inside the white house behind the scenes the last couple weeks when it comes to what the russian president is going for right now. we'll get a sense of that on tuesday. a very high stakes call. joe johns, holding it down on the white house lawn. thank you, sir. going to a shooting rampage at a michigan high school that left four students dead, another student charged with their murders. the man authorities believe might have helped ethan crumbley's parents for hours has dodged them. he said he was unaware that they were wanted. after learning of their arrest, he now contacted the police. as of now, sikora has not been charged with a crime. he has requested an independent third party investigation. i think one of the biggest questions since the parents were actually detained is what is going on with the school right now? what do we know about this potential litigation? >> reporter: we know the superintendent is calling for that in a letter coming out on saturday. since the day of the shooting, there's been a lot of questions about how the school handled ethan crumbley. we now know that on monday when ethan crumbley was discovered looking at ammunition on his cell phone, he told a school counselor that he had just gone to a shooting range with his mother recently and shooting was a family hobby. we know the school tried to contact his mother by phone and failed. tried to contact both of his parents by e-mail and did not hear back. we know on tuesday after a second counselor notified them concerning ethan's concerning drawings, ethan told the counselor the drawings depicted a handgun, blood on a body, images of ammunition. he said it portrayed a video game and he wanted to make video games for a career. police asked specific questions of ethan crumb ley. based on his answers, they said he wasn't a risk based on his calm answers. it was determined that ethan could go back to class because he didn't have any prior disciplinary infractions in his record. because of that, he was allowed to go back to class, but a key point in all of this is this superintendent writes that ethan crumbley's parents did not tell the district about the firearm or the fact they had just bought a firearm for their son. one of the confusing things is whether they asked his parents if he had access to a gun. phil? >> great reporting the last several days. athena johnson, thank you. critics are trying to emphasize the critical importance of masking and vaccinations and boosters. >> the next six months really depend on how we mobilize together to do the things that we know work. we know from a vaccine standpoint that the more mutations a single variant has the more immunity you really need to have in order to combat that variant, which is right now we're really pushing to get more people vaccinated and more people boosted to really boost that immunity in every single individual. >> as people in many parts of the world gather for the holidays, international travelers again face severe restrictions and mandatory quarantines as governments try to keep omicron from spreading. many of these new rules are aimed at arrivals from southern africa where omicron was detected. many people say this unfairly tracks african travelers. anyone else must have a test 24 hours before departing. nadia is following all the latest, but the bottom line to some degree is there is still a lot we just don't know about this variant, is that right? >> reporter: yeah, phil, and you heard that. you mentioned the media blitz, you heard health experts get out there talking about these interviews, what we know and what we don't know about omicron. fortunately at this point we just don't have the data to back up how transmissible it is, how deadly it is, not unlike what we know about the delta variant. that's why they said they have to do all these measures. then acenacted what people call the travel ban in south africa, a criticism of many, including one u.n. official calling this travel apartheid. now the obama administration starting tomorrow, their new policy rolls out where all travelers have to prove a covid-19 test the day before they travel. they have to get vaccinated as well to get into the u.s. that begins tomorrow. but there is still a big question about the vaccine, right? does the formula we have now, moderna, pfizer, j&j, does that formula work to protect us against the new variant? that's a question that dr. fauci answered today. take listen. >> with delta, when you get a level of antibody and general immune protection high enough, it spills over to protect against other variants. so we're getting quite good protection against delta when you're vaccinated, and particularly when you get boo boostered. that's the reason why we're saying even with a new variant like omicron, if you get boosted, you'll get your level way up, and we feel certain there will be some degree, and maybe a considerable degree, of protection against the omicron variant. >> so you heard dr. anthony fauci saying the vaccine, the booster is still your best shot against this variant and others. phil, we also heard from pfizer biontech. they said they can work on modifying their vaccine formula, but it will take some time. phil? >> no question about that. some positive news. more than 2 million americans getting vaccinated or getting boosters. it seems to be a trend over the course of the last couple days. some effect there for that variant. thau nadia, thank you for that reporting. i'll speak to a father that says social media drove his o daughter to take her own life. also ahead, bringing back new rules for asylum seekers. and calling out bigotry. >> which tells you their confer congress condones this and that's why it's dangerous. it's true jen. really?! this nourishing prebiotic oat formula moisturizes to help prevent dry skin. one day?

>> molly was an extraordinary daughter, and even though four years has passed, i still think of her every day and a tear comes to my eye quite often. there was no sign of any mental ill health in molly before her death, and we couldn't work out what possibly triggered it. then we looked into what she had been looking into online and saw the harmful content she had been exposed to on various platforms, including instagram. it was almost as if a missing piece of a jigsaw was put in place because it was so horrifying and shocking seeing that content. it must have been very hard for molly. and the platform's algorithms fed her more and more harmful content every day. having had a glimpse of what molly was exposed torq, i think now understand why she was pushed to do what she did. >> it was reported that in the last six months of her life, molly was using instagram more than 120 times a day. you later learned she had viewed a lot of distressing materials. you just mentioned about depression and suicide. you kind of alluded to this, but do you have any idea how much your daughter was using instagram so much and, more importantly, how toxic it was? >> i know the molly i saw and liked, i had to limit how much as well as the legal team which is working with us on molly's inquest which is still open, and for that matter, the police that were involved with the case as well. it's harmful, distressing material, sometimes quite shocking, but sometimes subtly shocking with benign messages. but if you are fed these messages by algorithm hundreds of times a day, you have to take an awful locat of care making se you don't spend too much time looking at that level of content. >> i've been aware of molly and the work you've done in the wake of her death. at the time, this was very high profile, particularly in the u.k., and instagram promised to make changes. the company released a statement that said, the company does not promote content that involves death or homicide. that was four years ago. are you aware of anything instagram has done to make it safer, in your view? >> they did come to the u.k. when molly's story broke here. i made the ann-- they made the announcement that said they would remove the graphic harms. all of those changes are welcomed, but you have to say why are they making changes reactively. they should be proactive. they have the data, they have the research, as facebook papers have shown. they have the resources, they have the data, they have the resources. they should be ahead of the curve rather than reacting. it's time governments around the world and legislation that's already been introduced, like the age-appropriate design code here in the u.k. and the calls from governments around the world for a safer online environment be heeded because that's what our young people who go online emerge. >> instagram put a pause on their instagram kids a couple months ago. they put out a message a couple weeks ago where they said they're proud of the progress instagram has made in making it safe for kids. they're trying to empower parents to implement parental controls. do you think parental controls, which is not a silver bullet here, would be a good solution? >> i think it should be looked into, but more important, will the world take stock of where we are? it could be used for so much good, but in the moment it's being spoiled because there is too much harmful content. so what we need to do is collectively look at the data we have -- actually, to be honest, that data is made mostly by the tech platforms -- that is the proper academic research that needs to be done so we better have an impact on their mental health. it comes from thousands of young people who will be affected. molly's story certainly inspires people to take action. thank you for being here. >> thank you, phil. ex white house chief of staff mark meadows is finally going to testify. what questions will he answer?

he will be sitting on the committee for the january 6 committee. he was there before, during and after the january 6 attack on the capitol. i want to bring in congressman pete aguilar of california. congressman, thank you for being here. do you ever a expense what mark meadows means when he says he wants to cooperate. it seems a bit ambiguous at this point in time. >> what we know is mr. meadows has been edge gauged with the select committee through his attorney, and it is a two-part test in order to be compliant with the work we are doing in protecting democracy here. one is providing documents, which he has started to do, and the other is sitting down for testimony and talking with us. so he has provided the first piece and continues to provide documents, and next we will sit down with him this week and engage. so we'll assess his level of cooperation only after that interview is done. >> the select committee chair, bennie thompson, will likely focus on excerpts that will be used in his deposition? >> i think the goal here is to ask questions and get to the truth, shoiz level of coope -- so his level of cooperation will be important since he's written about some of these items. i don't know, i haven't read the book, but we can ask about some of those pieces he has put into print. >> one of the things -- you guys have had a very different posture than, say, the very first impeachment investigation in terms of your willingness to be aggressive when it comes to contempt right off the bat. yet steve bannon was now formally charged with contempt of congress, and the committee plans to charge him for that still. why do you think that is? >> for every uncooperative individual, we've had many, many others who have been cooperative. over 250 witness interviews that we've taken. so there are a few outlyers, clearly. but we still have maintained a robust amount of information that we've been able to gather. so that's going to continue to be the posture that we take. and if individuals aren't willing to comply, clearly like we've shown with mr. bannon, there are some consequences they could face. >> and it's your sense, and the posture is totally different from past investigative committees, but have you guys been forceful enough and tried to compel individuals? are there other steps you can take at this point? >> i won't get into the investigative steps we are taking, but i think it does speak volumes that the amount of information we've been able to gather, 25,000 documents, they continue to pour in that is helpful in our effort of both questioning future individuals as well as laying the groundwork to build this report that will talk about how we need to protect democracy and what happened on january 5th and january 6th. so those are important components of it, and there are some outlyers, but clearly we are taking a focus of gathering the truth and thompson and vice president chene harris have takt up. >> before i let you go, you're a member of democratic leadership. there is plenty going on in your chamber right now, including this past week congresswoman ilhan omar dealing with republican lauren boebert. she said she asked the congress to take action for her comments. >> i have had a conversation with the speaker and i'm quite confident she will take decisive action next week. as you know, when i first got to congress i was worried i wasn't going to be allowed to be sworn in because there was a ban on the hijab. she promised me she would take care of it. she fulfilled that promise. she made another promise to me, that she would take care of this. >> just so everybody is clear and there is no kambiguity here she said omar is a suicide bomber. what action do you think should have been taken by those comments? >> i think the republican leadership should police their own ranks, and in years past they would have done just that. but not anymore. i think that's the bigger issue we see today, is the public leader continues to allow his members to go off and be racist, or in this case, islamophobic as well, and there is no consequence to that. and i think that's the broader issue that we're seeing under the dome in the capitol. but we will have that conversation this week, and within the democratic family, we'll come to a decision and we will implement that. but i think it's more important that we protect our members and that we do everything we can to ensure that this is a place where people feel comfortable. clearly that's not the case. the republican leadership lays a significant amount of blame for the current position that we're in. >> a broader issue that seems to be a weekly issue at this point, depending on where you are with that conference. congressman pete aguilar, thank you so much for your time. >> thank you. biden administration health officials out in full force today, reassuring the country that the u.s. has the tools it needs to take on covid variants delta and omicron. dr. leana wen is here to share her opinions. toothpaste is going to be pronamel repair. ok everyone, our mission is to provide complete, balanced nutrition for strength and energy. whoo hoo! ensure, with 27 vitamins and minerals, now introducing ensure complete! with 30 grams of protein. ♪ ♪ cases of anxiety in young adults are rising as experts warn of the effects on well-being caused by the pandemic. ♪ ♪ ♪ ♪ ♪ ♪ ♪ ♪ [uplifting music playing] ♪ i had a dream that someday ♪ ♪ i would just fly, fly away ♪ [ joe ] my teeth were a mess. i had a lot of pain. as far as my physical health, my body was telling me you got to do something. and so i came to clearchoice. your mouth is the gateway to your body. joe's treatment plan was replacing the teeth with dental implants from clearchoice. [ joe ] clearchoice has changed my life for the better. it's given me my health back. there's an amazing life out there if you do something for your health now. . more now on the emerging threat of the omicron variant. how serious is it? so far that answer seems unclear. senior medical analyst and baltimore health commissioner dr. leana wen joins me to answer your questions. she's also the author of "lifelines." doctor, we see a lot of reports that say omicron is only causing mild illness, but dr. fauci says more studies are needed. as a layman here only looking at those anecdotal reports, because they all seem to be -- positive may not be the right word, but they seem to all be better news than people thought six days ago. am i drawing conclusions? >> i think it's too early to tell but we are seeing that omicron is very contagious, that it seems to be outpacing other variants there. that's very concerning. on the other hand, it seems like most people who were getting hospitalized or getting severely ill are people who are unvaccinated. on vaccinated individuals, omicron does not seem to be causing severe disease, however, we need more studies to tell more sure and also immune escape. do the vaccines and therapies we have protect us well against omicron? they probably protect us somewhat and also giving a booster on top of it will give us those antibodies to protect us even more. >> my amount of patience for those answers is definitely showing even though it's been about a week. the doctor at the institute of health says omicron certainly won't be the last variant we see. we're still only at 60% vaccinated here in the u.s. over countries are far less protected. is it just a given at this point that we'll be dealing with this virus for years, maybe even longer? >> i do think that covid-19 is going to be here with us for the foreseeable future, but what we have to do is to turn this from an existential daily threat that we ever to consider in every aspect of our lives into something we can live with. i believe we are already very close to that point. we need to get more people vaccinated, of course, we also should have oral therapies, oral treatments that can reduce the likelihood of severe illness but also testing is going to be key. imagine if we can get to the point where students are tested before going to class, workers are tested before going into crowded conference rooms, people are getting tested before they get together for any holiday parties or events, that's how we're really going to begin to live with covid. >> i want to dig in a little bit more on something you said in the first answer. experts believe vaccines will likely continue to protect against severe disease, at least based on what they've seen so far, but the mutated variant, as you noted, seems highly infectious at this point. what are the dangers of that dynamic? >> if you have something that is a lot more contagious, even if it doesn't cause more severe disease, if the severity is exactly the same, you'll get a lot more people infected, and as a result, just based on proportions, you will get a lot more people who will become severely ill and that could still overwhelm our health care systems. on the other hand, what we hope for, the best case system, if you get a new variant that really does not cause a disease at all, that would be the best scenario. but i don't think we're at point where we can say this is the case for omicron at all. >> it would be nice to catch a break at some point. dr. leana wen, we appreciate your expertise as always. thank you so much for your time. >> thank you, phil. a trump era policy making a come back in the biden administration. the result a court is having with the so-called immigration rule, coming up next. c arthriti. some patients even felt less fatigued. serious allergic reactions may occur. tremfya® may increase your risk of infections and lower your ability to fight them. tell your doctor if you have an infection or symptoms or if you had a vaccine or plan to. emerge tremfyant® with tremfya®... ask you doctor about tremfya® today. ♪ ♪ there are beautiful ideas that remain in the dark. but with our new multi-cloud experience, you have the flexibility you need to unveil them to the world. ♪ why hide your skin if dupixent has your moderate to severe eczema or atopic dermatitis under control?

>> he continues to stand by those comments and statements and the secretary of homeland security put out a memorandum saying we want to end this program in. >> in a memo, secretary mayorkas says they are planning to end the program, saying it fails to add the fair process and humanitarian protections under the law but he can't cancel the program until the courts let him. it's unclear when that will happen and in the mean time as we've seen throughout the year, be it honduras or southern mexico, the border, migrants keep coming, although now coming to the u.s. just got that much harder. matt rivers, cnn, mexico city. ♪ so light 'em up, up, up light 'em up, up, up ♪ ♪ light 'em up, up, up ♪ ♪ i'm on fire ♪ ♪ oh-oh-oh-oh-oh, oh-oh-oh-oohohh ♪ ♪ in the dark, dark ♪ new cheetos boneless wings. exclusively at applebee's. people everywhere living with type 2 diabetes are waking up to what's possible... ...with rybelsus®.
