a month ago, we announced requirements that foreign travelers must be vaccinated if entering the united states. this week i announced an additional action to strengthen international travel rules to give us more time to stop the spread and study the new variant. it used to be that international travel, flying to the -- a traveler flying to the united states had to test negatively three days before their departure from that country. well, i'm announcing today that all inbound international travelers must test within one day of departure regardless of their vaccination status or nationality. this testing timetable provides an added degree of protection as scientists continue to study the omicron variant. and we are extending the requirement, both internationally and domestically, to wear masks for travel on aircraft, trains, public transportation, through the winter months. i'll close with this. again, the actions i'm announcing are ones that all americans can rally behind and should unite us in the fight against covid-19. and they come from a position of strength. we are better positioned than we were a year ago to fight covid-19. since day one of my administration, we've been doing everything we can to beat this virus. and that's what we have to keep doing. that's how we keep our country and our businesses and our schools open. even with the pandemic, we have generated record job creation. 5.6 million new jobs since january 20th, more than any president in american history. we're on the track to the fastest economic growth in four decades. in four decades. we've moved forward in the fate of covid-19 and the delta variant. and we'll move forward in the face of the omicron variant as well. and we'll do it by keeping the faith and doing it together as the united states of america. let me close again by saying god bless our doctors, our scientists, and all of you here at nih for what you're doing for the country and quite frankly, for the world. you're the best. you're the very, very best. my god bless you all. thank you for your patience in listening to me. thank you. [ applause ] >> good to be with you. i'm katy tur. as we come on the air, we have just heard from president biden at the national institutes of health, laying out his administration's new plans to combat a winter surge of the coronavirus. it comes as health officials report the second confirmed case of the omicron variant, this time a man in minnesota. officials say the man traveled to new york to attend a convention about ten days ago, then later tested positive back in minnesota and has already recovered. that's the good news. new york city's mayor said today people should assume there is already community spread and the state's governor, seen right here, urged people who attended an anime conference at the javits center in manhattan to get tested. that should surprise no one. we are also expecting to see many cases all over the place. the question remains how well will the vaccines hold up. the president's winter plan includes a more urgent plan to convince people to get the booster shots and easier access to tests. it does not, let me repeat, not include any new shutdowns or lockdowns, despite a disinformation campaign by people who want you to believe the opposite. the president himself has said if you are fully vaccinated, boosted, and wearing a mask indoors, there are no needs for lockdowns. there is also an important change you should know about, although it's not a restriction. starting next week, all travelers coming into the united states regardless of nationality or vaccination status will need to provide proof of a negative covid test within one day of boarding their flights, something a lot of other countries have already been doing. joining me now is nbc news correspondent heidi przybyla outside the national institutes of health in maryland, nbc correspondent jacob ward in san francisco, nbc correspondent antonia hylton in new york, and professor of infectious diseases dr. william scheckter. everybody, welcome. heidi, the focus is on getting vaccines and boosters. frankly the administration and health officials have been all over the place on whether you should get a booster. they're now all getting on the same page. is that message, though, going to get to folks, given where it started? >> katy, administration officials i've talked to say they now are doing everything they possible can, given gop opposition to mandates. but public health experts say they are concerned that it is not going to be enough, given what the rest of the western world is doing in year two of a pandemic when we have vaccines that are readily available. katy, if you look across the pond, much of the european union is making it virtually impossible for people to have normal lives, get on a plane, go to restaurants, unless you are vaccinated, using qr codes, so-called green passports. i talked to a global health expert who operates in 90 countries, and how she breaks down our approach versus other countries'. >> so unfortunately, my personal opinion, the u.s. is lagging behind. we have an administration that has not given the same consistent messages throughout the year and a half, two years. and we don't see enough action. we don't see a digitalization of vaccine i.d.s. we seem this in other countries, in the uk, in france, in belgium. from my perspective the u.s. is really lagging behind, and we see the results. >> and just today, katy, we're seeing germany talk about a potential nationwide vaccine mandate by february of 2022. you compare that to what's happening on the hill with republicans threatening a shutdown over vaccine mandates with death threats to the michigan governor over mask mandates. and you question, what are the other mandate levers that exist for this administration, which is also fighting these vaccine mandates in court earlier today. jeff zients, the national covid director at the white house, said that nothing is off the table. the big question now is whether there will also be a mandate for domestic travel, katy, now that we're seeing these mandates come into effect for testing for international travel. >> it is incredible lengths this country will go to politicize an issue, even one of public health. dr. schaffner, there is some news coming out of south africa about the omicron variant. it says there is a three-fold increase in reinfection if you've had covid, so reinfection even if you have the antibodies. one, does that surprise you, and two, what does it mean for the vaccines? >> katy, it doesn't surprise me a great deal, because let's focus on the severity of illness. in south africa, they're keeping these folks out of the hospital. these are relatively minor illnesses. we can deal with that, that's not so bad. actually it reinforces the fact that these vaccines are pretty good. the cases -- two swallows don't make a summer, but the cases we've seen in the united states, neither of those omicron cases have required hospitalization. looks as though the vaccine's working pretty well. remember, the vaccines are designed to keep us out of the hospital, to prevent severe disease. we can deal with minor illnesses 'til the cows come home, that's not a problem. >> that's a really good point. jake, the first case of omicron was detected in san francisco. we got news of it yesterday. what are health officials there saying today? and i'm curious, this person traveled back from south africa. any news on whether the people that were on the plane with this person have been contact traced? have they been tested? >> katy, you know, this is obviously a very scary development on the face of it, but here in san francisco there is the sense that there was some -- you know, not good news, but at least this bad news was handled extremely well. this person, whoever they were, this san francisco resident who traveled back from south africa, came here, detected that they were getting sick on november 25th and actually reached out to local health authorities and said, i have been in south africa, i know there's the omicron variant there. that's how their sample ended up here where they could do the gene sequencing and in less than five hours had the answer, they knew it was the omicron variant. all that person's close contacts including the passengers on the plane have been tested and tested negative, another good sign here. i spoke to dr. charles chu who runs the lab who did the gene sequencing here, has been working on zoonotic diseases for decades. he spoke about what happens next, now that they have the sample in their lab. >> what the identification of omicron has done for us, now that we have access to the sample, we're able to culture the virus, we're able to grow the virus in culture. by doing so, this is the first step for answering some of the critical questions that everyone has about omicron. is it more transmissible, what is the transmissibility relative to delta, is it perhaps more virulent or more severe, does it cause more severe disease, and also, does it impact the potential effectiveness of vaccines, does it affect the -- does it affect immune invasion or increased immune invasion from antibodies after being vaccinated or infected before? >> katy, in addition to his eagerness to get that sample studied so we can sort out some of what's going to happen with omicron here, he also made the very good point, we have to make it again and again, that the reason we have these variants is that people are not getting vaccinated. it's inside unvaccinated people that the virus has the chance to mutate, to develop these new variants. so he says, with a we've learned here is there's a good infrastructure here, this patient did the right thing, we've followed the playbook, but everybody has to get vaccinated before we're done with these variants. >> vaccines are readily available and there are whole populations around the world who are literally dying for a vaccine and don't have access to it. so it's a real big issue, not just for folks that are refusing to take it, but also access and our responsibility to get vaccines all around the globe. antonia, these new rules or this new rule to get tested 24 hours ahead of time goes into effect next week. it's a rule that a lot of other countries have had. if you were traveling internationally, chances are i did have to get a test before you went there. what are you hearing from folks who are just coming back here or traveling here today? >> well, in terms of on the ground right here, it is running the whole spectrum. i spoke to a woman earlier today who said, i'm vaccinated, i haven't seen some of my family in two years, i'm not canceling any of my winter plans, and i'm still getting on the plane. then i spoke to another woman on her way to bangladesh today who said, you know, i could see her fear palpably. she said she was afraid of getting on the flight, it was going to be many hours long, sitting next to people who she didn't know their health status, she's worried about health resources available to her while she's there. she says the last time instead of bangladesh it was very hard to find a good quality, quick-turn covid test that she would guarantee would get results back in the time window. she's worried she could find herself in a situation where she's not able to get back. i've spoken to industry experts in the travel and leisure space. they think this 24-hour window could have an impact on the industry more broadly. international travel is struggling to make the kind of comeback our domestic travel has been able to make over the last several months. listen to my conversation with one of the experts. >> international travel has already been struggling. we're not at 50% of what we were pre-pandemic for international travel. i think this will cause people to rethink some of those trips. any time you make it more complicated and more onerous, people are like, oh, man, i don't want to deal with this. hopefully we learn in a couple of weeks that this variant is not as bad as we feared and we can return to some sense of normally. at the points that we're not telling people to cancel trips. >> he also mentioned that, you know, it's possible that there are people who are going to see the threat that this new variant poses and other folks pulling back from their travel and actually see that as their moment to book a trip, to take advantage of deals at resorts around the world. so while we see some people pull back, others will try to take advantage of this. the reason we're seeing people react so differently is because we're still in this place where we don't know a lot about this variant and there's much that we need to have confirmed about the dangerousness and severity of the disease and its transmissibility in the coming weeks, katy. >> we should know sooner than later, a matter of days. everyone, thank you very much for joining us today. still ahead, the teen arrested in the michigan school shooting now faces charges ranging from murder to terrorism and authorities say his parents could also be charged. the prosecutor in this case will join me in just a moment. also ahead, though, the daughter of jane roe, her mother was at the center of the national debate over abortion rights. we're going to get her reaction to the current challenge to that landmark ruling. it is really interesting. later, a day in the life of a mom who was denied paid leave because her baby was born through a surrogate. . when you have an irregular heartbeat, it's more. it's dignity. the freedom to go where you want, knowing your doctor can watch over your heart. ♪♪ why hide your skin if dupixent has your moderate-to-severe eczema, or atopic dermatitis under control?

>> reporter: katy, plan "a" for democrats is to enshrine those federal protections into law through an act of congress. the house has passed that bill, it's gone over to the senate, but the senate is highly unlikely to pass it. it doesn't have a path to 60 votes to clear the filibuster nor do they have the votes to eliminate the filibuster. plan "b" is to take it to voters and democrats have a real advantage on this, a clear majority of the country supports the roe v. wade abortion rights protections. that includes majorities of college educated voters, suburban voters, and huge majorities of women, and where democrats' advantage lies is that conservatives have traditionally been more energized about roe v. wade. these protections have exist for about half a century now and many proponents of abortion rights have been complacent. democrats believe this will wake them up and motivate them to go to the polls. the house democratic campaign arm shared with me the prospect that if republicans take control, those same republicans could use that power to outlaw abortion rights at the state level or in congress which they might have the power to do depending on what the supreme court does. one republican senator, susan collins, made some news yesterday when her office told me that she supports codifying the protections of roe v. wade into law. let's post on the screen what exactly her office said. they say she is supportive of the right to an abortion and believes that protections in roe and casey should be passed into law. she's had some conversations with colleagues about this. now, it's notable that collins supports a narrower version of the women's health protection act. she wants some exemptions for abortion rights providers. collins' critics say this is a cynical political move to give herself coverage after she voted for kavanaugh and gorsuch who could vote to abolish the roe protections. >> i believe she said she didn't believe kavanaugh would be in support of overturning roe v. wade. we'll see what happens. but an interesting statement from senator collins' office, obviously you would need a lot more republican votes to get it past the senate. sahil, thank you so much. abortion was made a constitutional right in 1973 in roe v. wade, as i'm sure you know, but you might know not know who the woman at the center of that case was. jane roe was a 22-year-old pregnant unmarried woman who was struggling with her sexuality and alcoholism when she sought to have an abortion in texas. she could not have one and filed suit. as the case wound its way through the courts, she had the baby and she immediately gave it up for adoption. it was her third child. her two other daughters were also put up for adoption and they were all unaware of each other for years. only one of the daughters would have a relationship with their mother, norma. her eldest, melissa mills, who was dropped the by her grandparents. i spoke with mills earlier about her mother's place at the center of roe v. wade and what she thinks about whether abortion should be legal. melissa mills, thank you so much for joining me today. it is such a complicated issue, and your family and you are at the heart of this complicated issue. i just want to know, as you were listening to the arguments yesterday at the supreme court, what did you think? >> yeah, they're arguing -- there's so many complicated issues they're arguing about. i'm not a lawyer, i don't know how it's going to go, but i do see with the viability and all the complications of pregnancy, it's going to take away women's rights that we've had for over 50 years. and i feel like, for what my mother fought for all her life. so it's disturbing for my kids. it's disturbing for me as a parent, as a mother. as a health care worker. all those things. it's just real disturbing, that we're going to step back. >> i think some people out there might look at you and think to themselves, you were given up for adoption, you went to your grandparents, you knew your mother, your sister was given up for adoption, your baby sister was given up for adoption, she was baby roe, the baby surrounding this argument. >> yes, ma'am. >> given your relationship with it, some people might expect you to be pro-life, to be against abortion rights. why are you not? >> no, ma'am, because not everyone is meant to be a mother. my mother was one of those people. she knew it from the beginning. i mean, who am i to say that somebody is supposed to be a mother. it's the same thing, they're telling us we're going to control your body. i mean, you don't tell somebody they have to do something. and she knew from the beginning she wasn't -- she didn't want that role. and she always felt more like a sister to me, not my mother. we had a lot of fun together. but no, i wouldn't -- i would never impose on someone to make them do something they didn't want to do if they didn't feel that was the right, you know, way for them to go. >> part of the oral argument yesterday was about parenthood and part of the argument in casey was that parents, you shouldn't force somebody to be a parent. just as amy coney barrett tried to push back on that by saying, we're not forcing anyone, overturning roe wouldn't be forcing anybody to be a parent. i'm just going to play what she said. >> both roe and casey emphasize the burdens of parenting. and insofar as you and many of your amici focus on the ways in which forced parenting, forced motherhood would hinder women's access to the workplace and to equal opportunities, it's also focused on the consequences of parenting and the obligations of motherhood that flow from pregnancy. why don't the safe haven laws take care of that problem? it doesn't seem to me to follow that pregnancy and then parenthood are all part of the same burden. >> she says mothers can give up their babies for adoption pretty much immediately and they don't need to be parents. what do you make that have argument? >> well, that woman still has to remember that she had a child and that she couldn't take care of it and then she wonders the rest of her life. it's the double sword, either way you go. either way, it's not good. but you also put a lot more burden on the woman having to carry that child full term and in giving that baby up, and that's hard. that's hard on your body, your psyche, and everything else, the rest of your life. so either way you go, it's not a good situation. and that woman should have a choice on how she wants to live her life. i don't think that should be anybody else's decision but the woman who has that decision to make. >> the debate is so heated, and part of the reason why josh prager, who wrote the book about you and your family, said he wanted to write about the issues facing both sides for a better understanding. how do you wish the national conversation would go? what do you wish people -- how do you wish people would talk to each other about this? >> i wish they could see it for what it is. women have come so far in society, and we've made it to the part where we are almost -- we're there, we're -- we're trying to be equal. equal pay, equal rights. the same thing, we want everything. we want the stars. we want everything. and we shouldn't be held back by -- i don't like to say a mistake, but something that could hold our lives back and not let us move forward the way we want to move forward. i don't want to say the opposite sex doesn't have -- they can move forward easier, but in a lot of ways they can. so that shouldn't be anyone telling a woman what they can and cannot do to move forward in life. >> let me ask you that, because you mentioned men. when it comes to this decision, this issue, men don't play a factor, men aren't being held responsible for having sex. >> no, there's no man mentioned about any of the transgressions that have been. it's always the women. and the women have to pay for everything, i feel like, in the long run. they're the ones held accountable, not the man. >> the woman is being punished for the sex, not the man. >> yes. yes, ma'am. that's the way it seems. >> melissa, thank you so much for joining us, and thank you for lending your thoughts on this extremely complicated issue. i appreciate it. >> yes, ma'am. >> happy holidays. and with washington just hours away from a shutdown, house democrats say they have reached a deal to keep the government open. but there are some republicans who are already threatening to scuttle it. you won't believe the reason why. and coming up, a mom who was denied paid leave because her baby was born through a surrogate. - [narrator] every three minutes, a child is born with a cleft condition. without surgery, some will die. those who do survive face extreme challenges. operation smile works to heal children born with cleft conditions. we need you. there are still millions in dire need of healing. go to operationsmile.org today and become a monthly supporter, or call.

house democrats had reached a deal to prevent a shutdown on midnight friday, another short term measure to keep the government funded at least until february. but now a group of senate republicans led by utah's mike lee is threatening to let the lights go off unless there's a vote on adding language to the bill that would block president biden's vaccine mandate. >> i just want a vote on one amendment. i want the members of this body to go on record on whether they support funding in this bill president biden's vaccine mandate. we're providing every opportunity to avoid a shutdown. and all we ask for is a simple up or down vote. >> this morning, house speaker nancy pelosi seemed to be losing her patience. >> how do they explain to the public that they're shutting down government because they don't want people to get vaccinated? why don't you go ask them? this is so silly. >> nbc news capitol hill correspondent ali vitali and punchbowl news founder john bresnahan. ali, this is a group of republicans led by senator mike lee. >> this is a small group of senate republicans, katy, yes, because republican leadership and most of the other senate republicans we talked to say there's not the political appetite or upside for them to go into a shutdown over this measure. look no further than what senate minority leader mitch mcconnell said this morning. >> yeah, we're not going to shut the government down. that makes no sense for everyone, almost no one on either side thinks that's a good idea. >> nevertheless, katy, common sense doesn't necessarily always prevail here with these things. even though the majority of senate republicans say they don't want to do this, all it really takes is one or in this case three to gum up the process. what could effectively happen here is that if these several conservative republicans don't get what they want on vaccine mandate amendments, they could basically make this a slower process than it needs to be to avert that friday at midnight shutdown deadline. the basic order and regular order of the senate takes several days to go through this process. if every senator agreed that they wanted to speed this up, they could, but that doesn't look like the reality right now. so what could happen is that a government shutdown could be a casualty of just senate procedure going along through its regular timetable. what that means is we could see a shutdown over the weekend that ends early next week if this timetable holds. >> this is not just the lights in congress go off. i mean, we use that as a euphemism, john, but there's a lot of regular people who are affected by this, who won't get their paychecks, a lot of people in service to the federal government and in service to this meigs including military members who do not get paid if it does not get funded. i just don't understand the point of adding vaccine mandates to this. politically speaking, who benefits from this? >> there is a lot of opposition in red states to vaccine mandates. you have all these gop governors suing on this issue. there's -- of course there has been a lot of vaccine hesitancy and antivaccine positioning by republican lawmakers both on the hill and out, you know -- back in individual states. so i mean, politically, you know, there's, what, 30% of americans who are not vaccinated. they're still researching it or they're trying to figure out what they want to do. look, among republicans, what president biden is trying to do, this osha mandate is very unpopular. but the other point is here, the courts -- this has already hit federal courts. the federal courts have already, you know, blocked this rule from taking place, this is an osha rule. and they've blocked it from taking place right now until it's been litigated out. whether or not the president has the authority to do it. there is a question whether or not he's exceeding his authority by trying to force this rule through. so, you know, what's the point of having the amendment vote when the courts are already taking a look at this issue? that's what even a number of republicans raised to us, is, you know, the courts are already working on this. plus there's one other little wrinkle here. there's going to be another vote potentially next week on a different bill. why not wait for that bill and instead of shutting down the government, have your vote over there, you can knock down the rule that way. this is kind of a pointless stunt right now. >> and a federal appeals court has already blocked it so it's not even working right now. ali vitali, john bresnahan, sorry it's so short today, thank you for coming on. next, the fight for paid family leave. we're bringing you the personal stories of parents struggling without it. today we meet natalie welling, a west virginia mother of four. natalie is a respiratory therapist. her job does not provide paid leave. since her baby was born through a surrogate, she was not eligible for disability either. so natalie took six weeks of unpaid leave. here is a day in the life of west virginia mother natalie welling. >> so it's 10:00 in the morning, and i am having my coffee. i've not slept, lennox hasn't slept. i just got him laid down for a nap. i'm going to try to fit in my household chores, laundry that's piling up with cloth diapers and being a family of six. and i'm really missing my husband today.

>> reporter: katy, there will actually be a press conference in about an hour or so where we'll hear from the county sheriff not on the investigation, but instead an unfortunate consequence of this school shooting that you're seeing in this area, and that's the idea of copy cat threats going around the school districts here. more than 33 schools and districts in this area are closed today because of those threats. you hear officials calling it a tidal wave of threats coming in. we'll expect to hear from the sheriff, from all their elected leaders about how they're addressing those threats and presumably we might get some information on the investigation if they do take questions on that. meanwhile, the investigation does continue. and you mentioned, it focuses on that journal that they found. it focuses on the video that was recorded, they say, in the hours before the school shooting started, the next before, when they say the 15-year-old suspect, a sophomore at the school, recorded videos talking about wanting to kill other students in his school. the shooting resulted in the deaths of four students there. and three others are still in the hospital right now. at last check at least one person, according to authorities, is in critical condition at this point. so that's the latest right now. we'll keep an eye on that press conference later this afternoon to see if they do address any updates in this investigation, katy. >> shaq brewster in michigan, shaq, thank you so much. lear with me is michigan prosecutor karen mcdonald. thank you for being here. i'm just wondering, as you look into this case, if there was a way to see this coming. the kid had a meeting with his parents and the school just hours before he went allegedly on this rampage. was there no indication? >> it's difficult for me to comment on what somebody else knew. i can tell you that we are reviewing potential charges against mom and dad. and, you know, based on all of the evidence that we have so far, i can only say that i think that this was absolutely preventible. >> why would you want to charge mom and dad? >> well, if you knowingly have -- if you own a weapon or possess a weapon and you knowingly allow someone to have free access to it, who you have reason to believe might use it to injure somebody, that is willful. it's gross negligence. and there are lots of criminal consequences for that. you have to -- owning a gun is a right, but you have to have responsibility with it too. and if it's not safely stored, if it's not secured, that's not responsible gun ownership. and it can oftentimes result in a criminal charge, just as you wouldn't leave a gun on a table and let a 3-year-old grab it. >> i certainly wouldn't do that. did the parents give this as a present to ethan? the instagram post where he's holding the gun, he says here's my new gun, it's a sig sauer. do we know if it was a present to him directly or was it something bought for the family and just not locked up? >> i think the post that you just talked about that's public, certainly indicates that he viewed it as his. we know that dad purchased it. and then the other evidence that exists, i can't comment on right at this moment. >> are the parents cooperating? >> we have not interacted with the parents. and, you know, it really isn't a matter of cooperating or not. it's whether or not somebody chooses to talk to police officials. and they have a right not to talk and they have a right to talk. so i don't comment on whether they've made statements or not. >> explain the terrorism charge here. it's a new one. >> it is. i didn't really appreciate that, nor did it really matter. as we sat over this and looked at this evidence and viewed these tapes and watched the horror that took place, you know, we have our first-degree murder charges. we have assault with intent to murder. and those reflect what happened to these kids that were murdered and injured. but there was not a charge that reflected the victimization of thousands of students in that community, kids who can't eat, who can't sleep, who are so afraid that they can't even imagine stepping foot back into that classroom. and, you know, school is a safe place. that's what we've taught our kids, school is a safe place. as a parent, when you drop your parent off to school, that's just one place you don't have to worry about them, that's what we think. and that should be the case. and so this has really caused harm and terrorized an entire student body. if you view the images, it's clear as day. and they're very difficult to watch. and so i believe that's an appropriate charge. >> i will just add, the suspect, according to the sheriff, exhibited concerning behavior just before the shooting, so concerning that two teachers reported it, yet it didn't make it to the policy. prosecutor karen mcdonald of michigan, thank you so much for coming on and explaining these charges, and the severity that the parents could be facing as well. we appreciate your time. >> thank you. and coming up, jacob soboroff has a rare look at operations at one of the country's largest railroads and how its workers are navigating supply chain problems. ♪ limu emu... & doug ♪ ♪ superpowers from a spider bite?

>> not as fast as possible. >> kristen south told us there aren't enough truck drivers to get cargo out fast enough. >> almost 50% will hit chicago on its journey at some point. >> reporter: that's not always how it happened here. the factories closed as manufactured moved overseas. now what's produced there ends up here. >> so, this place wouldn't even exist were it not for the contraction of domestic manufacturing and the move to international trade. >> you're exactly right. >> reporter: 40% of goods traveling long distances in the u.s. move by rail. and the department of transportation expects total freight demand to grow by 20% by 2030. which is why union pacific is banking on autonomous technology, including this crane. >> this is it, huh? >> this is it. this is going to be 100% humanless operation. >> can you see how tight i'm grabbing the railings now. wow. so, the trains come in here. >> correct. it's going to move around all day long. >> reporter: and the only humans to work on the crane won't be anywhere near it. >> you're telling me the potential solution to the supply chain crisis could look a lot like playing a video game. >> maybe not the full solution, but it'll be a lot more efficient. >> reporter: just as the factories wednesday overseas and the comply chains lengthens, the trains here have their own consequences. >> they want to automate. they want to get you guys in and out sfas possible. >> you want to hear the bad side about that?
