administration's week-long tour. but the focus today on aide for small businesses. in a few hours president biden takes his message to pennsylvania's delaware county. >> we have not had great vaccine distribution in delaware county and i'm sure he will also those questions for all of the people. >> multiple headlines out for the coronavirus pandemic. moderna saying they started vaccine trials for children. one vaccine is ramping up and another is under the micro scope. they say there is no indication that vaccination has caused blood clots. it comes after 13 european countries stop the use of the vaccine. join me to hear what that means for the global vaccine rollout. carol, good morning what can we expect to hear from the president later this afternoon. >> this is the president's first stop. and administration officials are trying to sell this $1.9 trillion bill. from philadelphia where i am and going to a small business. there is provisions for small businesses and there is some $50 billion in relief that the president wants to highlight. they have minority owned small businesses and that's the focus today. and this is really just part of a broader effort to do several thing rs in terms of the officials that are out across the country. trying to begin up continued support for this bill. it's understanding what is in the bill that benefits the white house. maintaining support as you know this is widely popular across the country, and also getting a little credit for what the president feels is one of his biggest victories so far since he has taken office and not -- also building on the momentum that they feel might give them to whatever battles they fact right now. >> while we have you they are a tack hike, a tax increase. this is something that previewed last week. nay say they're looking at sax increases for the next plan, the next legislative initiatives it is a very large infrastructure bill in congress, and the issue is how do you pay for something like that? they want to do something even bigger. and so the way they're talking about paying for it is potential tax increases. what we heard from the white house is that the president still does not support raising taxes on americans that make less than $400,000 a year but he supported increasing taxes on those that do make more than 400,000 a year. so this is setting up to be not only a fight in the democratic party, but this is something that are not clear why they would get support for something like this. >> carol lee in philadelphia, ahead of president bite's trip here today. now more on that rising number of countries announcing a full or partial pause on astrazeneca's trial. they are temporarily suspending use of that vaccine after reports of blood clots in some of the people that got it. the vaccine is according to a update just out from europe's medicine regulator. as the company defends the safety and they meet with experts today about all of these concerns. kier simmons is in london, and so it dr. tom freeden. keir, we'll start with you. the u.k. is not joining these other countries in suspending, but what steps are they taking as the safety reviews move forward. >> yeah, it is partly a -- a third of the u.k. have been vaccinated, partly with the astrazeneca. there is country that's have paused that astrazeneca rollout. it is a nightmare not in the least because of safety concerns but because of the effect it might have. s a astrazeneca has reported serious blood clots, and it's not even clear. senior scientific advisors are saying this. and there is no link between the blood clots and the vaccine. they suggest it is at a normal rate for the population without any kind of a vaccine. and then you have this escalating third wave of virus. caused by these variants. they're going to lose their easter again. in france around 4,000 people now in intensive care units in france. it's such a serious situation in poland. the worst since november. germany seeing school children increasingly infected. europe is really struggling. it's not wrong to say frankly, jeff, that this is the biggest test for europe this century. >> keir simmons, thank you for your time this morning. what do we know about these cases of blood clots in people that receive astrazeneca's vaccine? and what kind of information will experts will looking at as they try to learn more. >> when there is a concern you have to be completely transparent and say this is what we know, what we don't know, and what we're going to find out. we know a tiny fraction of people that got one vaccine, not in use in the u.s., have had blood clots. they're not that uncommon. so the next question is is that risk increased from the vaccine or is it coincidental. lots of things happen, and the fundamental question is is there increased risk? the next question that countries have to ask is while they investigation that will they continue to use the vaccine? certainly if you have explosive spread of covid, the risk is far greater than a risk of but it is really supreme importance to make sure that you maintain confidence by being completely transparent. so i think that it is important that there be rapid and thorough investigation. what was the timing of the cases? how serious were that, and what is the baseline or the background rate of those conditions? was it elevated? before the vaccine program starts, you can check in realtime is it higher than expected or not. so far i want to emphasize that we have not seen serious adverse events. none of them have been fatal. they have all resolved. lots of people have a sore arm. some people have fever or fatigue, but that is better with the vak seens being used in the u.s. within a day or two and in everybody. >> let's talk about the news out of moderna. they talked about a trial for vaccinating children. that is already in motion. what are experts watching for when it comes to trials in the younger age groups. especially when we talk about infants. are these instances where their parents are signing them up for medical trials? >> it is really encouraging. we're seeing more and more good news on vaccines and vaccinations. more people getting vaccinated. we're up to over 100 million doses given. more than 65 million people have starts vaccination in the u.s. and we're seeing plummeting death rates even where covid is spreading. so you're seeing lots of progress with vaccination. i think the novavax vaccine is likely to be approved in the next month or two. but one of the issues is that we don't yet have a way of assessing the safety and efficacy in children. or the dosage. one of the things they will do is' what dose should be used. fundamentally even though kids tend not to get spherely ill with this infection, there may well be a need to vaccinate some of the kids. there is some evidence they spread more among children and this, always it is often minor, is not always a minor infection. some children have died from the complications from covid from the immune response and from the decide. so it's great that we're looking at the safety and efficacy in more groups including kids. >> is the time table to approve vaccines in children, is that longer than the time table for adults? should we expect these trials to last potentially years? >> interestingly the more uncontrolled spread of covid there is the quicker you get a answer. that is one of the reasons that the vaccines have been able to get approved so quickly. a lot of money was spent to get these to market quickly and you were able to have cases accrue so you can see the difference. but i think if things go well we would be looking at late summer to fall and we might have approvals for younger children. >> thank you for your insights this morning, we appreciate it. fema is now involved in the massive surge of migrant children arriving in the u.s. alone. we will take you to a facility that one official calls the epicenter of overcrowded. wells also hear from a mother whose 4-year-old daughter was held there. and a new bill to make daycare and childcare facilities covid safe. we'll talk to the lawmaker behind the bill, katherine clark. bill, katherine clark. dry smells more amazing than ever. isn't that the dog's towel?

>> yeah, these schools have been open since september and from september to december they have only seen a positivity rate at schools of about 1%. how are they doing it? in a partnership with pediatric infectious disease experts who made checklists for them. six feet or three feet with plexiglass. contact tracing, they have a team of nurses here, about eight nurses, trained by the state health department to test children and take them out when they know they're positive. we have been talking about this a lot, ventilation. this is a pretty new school but even for older schools they show us this filter, it can be retrofitted on to the ventilation systems of old systems. and finally we talked with a pediatric disease expert, jeff, that stressed that this is so important. that schools get the message here as they reopen that this pandemic is not behind us and yes, it hold risks for children that will not be vaccinated until next year. take a listen to what she had to say. >> one thing that i try to tell many people who say oh, well, children just have mild disease and it's not a big deal is that we don't know the long-term effects of covid. even when you have mild symptoms. there are some studies showing abnormalities in children even with mild symptoms and we hope that those go away. but we don't know whether or not there are long-term implications of having covid. >> jeff, so dr. eckhart told me with so many adults getting vaccinated that they want to drop protocols, but now is not the time to do that especially with these new more contagious variants. >> thank you, with me now is assistant speaker of the house. katherine clark who is a democrat from massachusetts. good morning. hidy just reports on the challenges that schools face and you're reintroducing a bill today. explain what your bill does and how it is different from money that was set aside that just passed in the american rescue plan? >> yes, well i'm very excited to be reintroducing this bill because what we know is that child care is vital infrastructure. it is not only good for parents and good for children, but it is good for our economy. and this bill is building on and making permanent the work that we started in the american rescue plan to stabilize the childcare industry. it will make investments in all of the things the last segment talked about. helping upgrade and ache our child care centers and homes safe places for both providers, children, and families. it is also going to offer educational support for our childcare providers. who we know work for very low wages. 96% of providers are women. 40% of those women are women of color. it is kritt kal that we accomplish a pathforward so we can continue to recruit and retain professionals in early education. and finally it will help the student parent by proviing safe, affordable places for children to be while they're parents are in the classroom. this is all key to our recovery and changing the paradigm around childcare from a private decision of families to recognizing the public good that it is. >> your bill was approved as part of a larger package in the house, but it didn't move forward in the senate. is there enough political capitol, do you think, on the hill that is left? >> i absolutely think so. i think that what the pandemic did was change the way that we view childcare. we're now looking at women in particular leaving the workforce primarily because of care issues. two million women have lost their job. we're at a 33 year low of women participating in the workforce. one million of those women are moms. and we know that child care is the vital link for them being able to get back into the workforce. we're hearing from the business communication around the country that they understand the vital link between affordable and accessible child care and making sure their businesses can reopen successfully. this is the time to take these lessons from the pandemic and help our childcare providers provide krit a i recallly education. so that our participants have the help they need to be successful and get back to work. >> while we have you i would also like to ask about security at the u.s. capitol. the washington post is out with exclusive reporting that the army initially pushed to reject the dc government's request for a modest national guard presence. and according to an internal draft memo it says they should not be needed to help police with traffic and crowd management as city officials requested unless more than 100,000 demonstrators were there. what red flags does that raise for you and does it give more urgency to the forming of this 9/11 style bill they have been pushing for. >> absolutely. i have been involved in multiple areaings. we have soon there was a disconnect between the intelligence that we had and the support that was requested but was too late in coming to the capitol. as a result we had a loss of life. we had serious injuries particularly to our capitol police officers. and it could have been so much worse if we did not have capitol police officers acts so behave ri that day. but what we have to look at are the root causes that what is -- you know we know this mob was fuelled by racism and hate. we know there was white spremist groups there, and this is an on-going threat to our security. we have to everything that we can to make sure that we secure the capitol and by doing so that we secure our democracy. that is what was threatened that day. that threat continues to exist. and that means getting to the bottom of all of this. and why wasn't that help coming? why weren't we prepared? and how are we assessing the risk differently because we knew this was fuelled by excite supremacy. all of this i hope will come out in a 9/11 style commission. the speaker has proposed. and we're waiting for the republicans to give a response and to enter into ocean if they want to see changes in how that commission is set up, but we're not waiting to pursue the truth. we're doing that in our committees and we will continue to push to have a nonpartisan commission that can look at all of the different pieces and see how the failure to secure our democracy and our capitol occurred. >> okay, katherine clark, thank you for your team this morning, it's great to see you. >> a thank you. >> as we talk about the capitol insurrection, two men have been arrested accused of assaulting a capitol police officer who died. next up, new details on the charges both men are facing. de charges both men are facing. needles. essential for pine trees, but maybe not for people with certain inflammatory conditions. because there are options. like an “unjection™”. xeljanz. the first and only pill of its kind that treats moderate to severe rheumatoid arthritis, psoriatic arthritis, or moderate to severe ulcerative colitis when other medicines have not helped enough. xeljanz can lower your ability to fight infections. before and during treatment, your doctor should check for infections, like tb and do blood tests. tell your doctor if you've had hepatitis b or c, have flu-like symptoms, or are prone to infections. serious, sometimes fatal infections, cancers including lymphoma, and blood clots have happened. taking a higher than recommended dose of xeljanz for ra may increase risk of death. tears in the stomach or intestines and serious allergic reactions have happened. needles. fine for some things. but for you, there's a pill that may provide symptom relief. ask your doctor about the pill first prescribed for ra more than seven years ago. xeljanz. an “unjection™”. want to make a name for yourself in gaming?

>> i think right now the focus turns from arresting expects to finds out why he died. they need to get evidence from the medical examiner pointing to his specific cause of death and did this alleged assault with this chemical irritant that is based on one of the statements from the person who allegedly sprayed it, where he told his co-conspirator. he said give me that bear expletive. so it is assumed it was bear spray. if they find that i think you will see the charges upgraded here. you mentioned something before that i think is an interesting question and a good point with respect to how they do it. we were able to dig up yesterday the search warrant in this case. and in the search warrant it lays out some of the steps used to identify these two individuals from internet tipsters. we looked at the videos and the images of these two involved in this act, we see that it is a little bit -- the images are not very clear and they relied on internet tips. and one of his former co-workerings led them to this person into there may be a reason why it took awhile. the washington field office continues to put out new imams, people of interest, so i expect more arrests in the coming couple of days and weeks, but this is a very important one because it does involve the assault of a police officer that may have lead to his death, jeff?

is also asking to move the trial out of minnesota. they say the announcement of a $27 million settlement between the city of minneapolis and george floyd's family could taint the process. how long do we expect to hear from the judge and how long of a pause would be granted if he were to grant this motion. >> it's hard to say when we're going to hear from the judge, but what is most important is that nothing is broke p here that can't be fixed. there might have been an advantage for waiting until the end of the trial, but they're announcing it and the world is watching now. the jury has not been empanelled. we have two weeks to finish the jury election and that is an eternity. the judge will think very carefully about what to do next. it makes perfect sense for for them to ask what they're asking for, but i think when all is said and done they will don't it in mipz. >> so the question is, what happens if they have heard about the settlement. >> if they heard about the settlement, it has been the same. can you put aside what you know. that will be one additional concern. they're supposed to be staying away from the media. if they broke those rules that will be a red flag for whether or not they can follow a juror. here is what everyone needs to remember. they set aside three weeks to pick a jury for a reason. the reason that we have so much time to pick this jury is to account for these kinds of things. it is a historic case, there is more than enough time to fix these problems. >> as we talk about this, how do you believe prosecutors need black jurors to convict for you have two black men, a hispanic man and a woman who identifies as multiracial. so what's your take on that mix there? speaking in generalities, of course. >> absolutely, jeff. i know you can't reduce someone to the specifics of the color of their skin. what we've seen in these trials over and over again, when they actually go to court before a jury you need at least two black jurors to have the likelihood of success. at this beginning of this jury selection i thought we needed two. in this case, based on what i've seen during jury selection, i think you need at least one more to have a fighting chance. and that's because of the way the jurors tend to make their choices. one of the hardest things to accept as a young attorney when you start trying your case, juries tend not to sympathize with your client or the person at the center of the trial nearly as much as you would like them to. jurors tend to make their decisions based on their personality safety, based on how they feel, and the advantage you have with black jurors in a case like this is you don't have to orient their point of view. they already have a visceral response to seeing that video, and it makes them fear for their own personal safety if the right outcome is not achieved in the trial. >> civil rights attorney and former prosecutor david henderson. david, we appreciate you. ready for

arriving at airports for the first time in over a year. and they're finding that the experience there is a lot different than what they might remember. nbc's tom costello is covering all of these changes as part of his future of travel series. >> reporter: hey, jeff, good day. the cdc is still advising against air travel right now. that could change in the coming weeks or months. but in the meantime americans are getting vaccinated, states are lifting restrictions, and people are anxious to get out of the house. so we decided to take a look at what's changed if you haven't flown in the last year, what's changed from the moment you arrive at the airport all the way through the trip. before you travel if you're going to a destination that requires a negative covid test you should take

change my seat, and where is my gate? but i guess you're not as susceptible to briby for an upgrade, right? i can't hand you a box of chocolates to get my upgreat. >> no, but they still try. they
