christmas as shipments are stuck at sea. what's causing the backlog? the dangerous journey for haitian immigrants heading towards america. >> reporter: for all the people on that boat, this is the only way to the other side. >> o'donnell: and the box brigade: what these do-it- yourselfers are doing to fight covid. this is the "cbs evening news" with norah o'donnell, reporting from the nation's capital. >> o'donnell: good evening, to our viewers in the west and thank you for joining us. we are going to begin with a story of panic and fear that has become all too familiar in thida school. this time in north texas, and it started with a fight, then gunshots. four people were hurt, including one student who was critically wounded and the gunman fled the scene. students and eachers took cover. police descended on the high school in a massive show of force, searching room by room to make sure the threat had passed. and as word spread, anxious parents gathered as close to the school as they could get to wait for news. the students were later evacuated by bus. hours later, the suspect, who is 18 years old, turned himself in, and tonight, he faces multiple charges. cbs' mireya villarreal is going to lead us off tonight from arlington, texas, with new reporting. good evening, mireya. >> reporter: good evening, norah. one of the victims was a teacher. his sister posted on social media this afternoon that the bullet that hit him barely missed his aorta. hasn ribs llapsed lung but he is expected to pull through. chaos at timberview high school after ca of an active shooter. heavily armed swat teams rushed to the scene and entered the building looking for the suspect who had fled. arlington police say 18-year-old timothy simpkins was involved in a fight a fight with another student. at some point during the fight, he drew a weapon and started shooting. >> just based on the information, i know there were more than-- more than two or three shot that were fired. >> reporter: the shooting left four people hurt, three of them hospitalized. one, english teacher calvin pettit, was rushed into surgery. panicked student and staff barricaded doors with their desks and hid inside their classrooms. dale topham was teaching close by. >> so my mindset was if somebody gets to that barricade-- which they won't-- but if they do, if they want to hurt one of these students they're going to have to take me out first. >> reporter: you can see the fear in this conversation between a student and her mother saying, "mom, there's a shooting. please, i'm scared." so far, this year, there have been 21 school shootings, 80 since 2018. last year, during the covid-19 pandemic, when most kids were doing remote learning, there were 10. after a short manhunt, simpkins turned himself in with his attorney this afternoon. the weapon allegedly used in the shooting was found two miles from the school. there is video of that original fight that is circulating on social media and it has been shared with police. but students are saying right now that the kid that is getting beat up in that video is actually the suspect. he is now facing several charges of aggravated assault with a deadly weapon. norah. >> o'donnell: mireya villarreal, thank you. well, in a visit to chicago on thursday, president biden will talk about the impact that covid vaccine mandates are having. with new cases, hospitalizations, and deaths all slowing in recent weeks, the administration is also underscoring the need for rapid, at-home covid tests. we get more on this from cbs' omar villafranca. >> reporter: while covid casesis and hospitalizations decline nationwide, the demand for at- home tests is surging. but today, a company that manufactures some of these test kits, ellume, recalled some kits due to false positives. the kits were widely available to consumers and also provided to the u.s. department of defense. >> every american, no matter their income level or zip code, can access accurate, convenient, and affordable testing. >> reporter: this comes as the white house announced today it's investing an additional $1 billion in at-home test kits, quadrupling the amount currently available on store shelves. the los angeles city council today announced one of the strictest vaccination requirements in the country. as of early november, customers must show proof of full vaccination to participate in many indoor activities. >> i know we're in a different time right now, so it's, like, we have to do what we have to do right now.o >> reporter: kids still make up more than a quarter of new cases. in florida, where the governor attempted to bar school districts from requiring masks, some parents of children with special needs are suing. >> we're at around a 10% community transmission right now. and that's just too high for us. it's too dangeor her0- year-old son, will, who s syndrome, toenschool in pers >> there you go! >> reporter: the lawsuit contends an executive order signed by governor ron desantis in july violated the americans with disabilities act. >> it's been an uphill battle. he is 10 years old. it has been an uphill battle his entire life so this is just the latest battle in the war, i think. >> reporter: we reached out to the school district, but they won't comment on pending litigation. an f.d.a. advisory committee is scheduled to meet october 26 to discuss vaccines for kids between the ages of 5 and 11, which means we may see those shots roll out around halloween or early november. a spokesperson for the american academy of pediatrics says thoso shots could roll out at pharmacies, vaccine clinics and hospitals, which includes pediatric offices. norah. >> o'donnell: certainly before thanksgiving. omar villafranca, thank you. tonight, as america inches closer to a catastrophic default, there is news about a possible deal in the senate, and it can't come soon enough. the treasury department warns it is running out of ways to payntt is running out of ways to pay the the nation's debts in 12 days, and inaction from congress ould be disastrous. cbs' nancy cordes reports. >> reporter: with washington hurtling towards insolvency, republican leader mitch mcconnell offered a surprise concession. he said his party would let democrats raise the debt ceiling short-term for about two months. >> why should we accept any part of a b.s. offer? >> reporter: the new offer came as president biden poured on the pressure. >> it's about paying for what we owe. >> reporter: enlisting major banking c.e.o.s to help sound the alarm. >> we are starting to experience elevated volatility in the markets. >> the cascade effects in the ensuing weeks could go anywhere from a recession to a complete catastrophe for the global economy, and i don't know why anyone would take a chance like that. >> reporter: defaulting could also disrupt social security payments for nearly 50 million seniors and military benefits for two and a half million veterans. price. >> why? >> reporter: lewis franklin served two tours in iraq. >> there's no reason for it, other than it's a giant chess game that the senate and the house play, and we're the ones who pay the price. it sucks. >> reporter: republicans say they don't want default, they're just trying to highlight the democrats' multi-trillion dollar plans for new social programs. >> we'd kind of like to know how much money they intend to spend. and they don't want to say that, because i think when they do, the american people are going to be the first ones to object to it. >> reporter: tonight, democrats appear to be leaning towards accepting this g.o.p. deal and raising the debt ceiling temporarily. if they do, then the nation will be able to pay its bills for now, but we would likely be watching this exact same fight play out a month from now, watc norah. >> o'donnell: nancy cordes at the white house. thank you. facebook c.e.o. mark zuckerberg is hitting back after that scathing testimony from former employee frances haugen tuesday. in a note to staff-- not publicly-- the company founder wrote that haugen painted a false picture, adding it's difficult to read the allegations about how instagram impacts young people. as congress weighs how to regulate the social media giant, cbs' kris van cleave tonight has a look at potential solutions. >> i was comparing it to myself. >> reporter: teens like jada bromberg are at the heart of the debate over facebook. she started using their instagram app at 13. without realizing it was happening, she says the app was contributing to feelings of depression. >> but looking back at it now, i can realize how social media definitely kind of put some of that in my head. >> reporter: while facebook c.e. mark zuckerbergs rese a tmpon teens is being mischaracterized, calls for change are getting louder. >> what i want to see is action in this place. >> reporter: congress is weighing how to regulate social media. whistleblower frances haugen tuesday: >> we can afford nothing less than full transparency. >> we shouldn't have to wait for the whistleblowers to whistle before we understand what is actually happening on these platforms. >> reporter: nate percely runs the stanford cyber policy center and has proposed legislation to runs to require social media platforms to give researchers to give researchers access to how they give researchers access to how they operate. >> one of the interesting things about frances haugen's testimony is that it offered a rare window into the inner workings of facebook and what is actually going on on the platform. and until we get greater transparency from the companies we can't legislate any responsible way. >> reporter: facebook says it supports additional federal oversight. do they really support more regulation? >> i think they do. i think that facebook is at a position right now where they want somebody else to solve their problems. >> reporter: norah, congress is is looking at a host of options, and that includes placing limits on political advertising and marketing directed at kids. in the longer term, there's talk of allowing social media companies to be sued over content their systems amplify. talkabout gulating socialbeen media for years, and they've yet to do it. >> o'donnell: and congress seems to have trouble doing a lot of things lately. all right, kris van cleave, thank you. well, tonight, there are growing concerns we could see empty store shelves this holiday season. a lot of shipments remain stuck at sea because of supply chain issues. so who's to blame? and what's being done to fix it? cbs' carter evans went looking for answers. >> reporter: normally, you have more barbies? >> normally the whole thing is barbies. >> reporter: holidays sales are high stakes for toy stores. you think you're going to sell out this year? >> we're absolutely going to sell out. if you want a train for christmas? >> buy it now. >> reporter: store owner maryam al hammami says almost all of her toys are already out to the floor. she started ordering for the holidays in march. so what happens when the stuff on your shelf here sells out? >> i don't have anything to replace it with. >> reporter: new orders likely won't arrive by christmas. that's because goods made overseas are spending a record amount of time in transit. cargo ships are crowding ports from new york to los angeles, where a quarter million containers are currently floating off the coast, according to l.a. port director jean siroka. these stacks of containers seem to be growing. >> there's no room to put this cargo. our docks are full. only half the truck drivers registered to do business here visit us at least once a week. we need more truckers on the job. >> reporter: trucker george anaya says the port needs to move faster. you had an appointment at 7:00 p.m. to pick up a load. >> yes, i didn't get out of there until about 2:00 a.m. >> reporter: before this year, how many loads a week could you pick up? >> about 20 or so. >> reporter: and how many now? >> about six. >> reporter: the port of l.a. does not operate around thear of the worof the presidt biden has saidd like to see the ports operatin 24 hours. why isn't that happening? >> you've got so many nodes of the supply chain that have to get on the same schedule. if we can get the warehouses to open around the clock, that would be important to us. >> reporter: 40% of al hammami's business depends on holiday shopping. >> it's tough as a consumer, because i also am going to celebrate christmas. and it's tough as a business owner. >> reporter: it's gotten so bad, that some large retailers are going to extremes just to avoid the logjam here in los angeles. companies like walmart have chartered entire ships to deliver goods to less-congested ports. of course, that adds tremendous cost that small businesses just can't afford. norah. >> o'donnell: yeah, hurting small businesses. carter evans, thank you. well, tonight, we're learning re abo that isis suicide bomber behind the deadly attack at the kabul airport. cbs news has confirmed the terrorist had been freed from an afghan prison just days earlier by the taliban. he was among thousands set free as the u.s. withdrew from afghanistan. 13 u.s. service members were killed, and 18 wounded in the attack. more than 7,000 haitian migranti who entered the u.s. in recent weeks have now been expelled. but that is not stopping many who are risking their lives to travel thousands of miles from south america to the u.s. cbs' manuel bojorquez met some of them on the colombia-panama border, where hope and hell collide. >> reporter: the scores of migrants who have set up camp along the caribbean town of necocli are among the estimated 16,000 waiting in colombia to head north. leon nelson fled disaster stricken haiti years ago to settle in south america where jobs have dried up. he can't take his wife and infant daughter back to haiti he says. nothing in haiti, no work. their goal is to reach the u.s. deportation. it's a big fear for you. as they finally get seats on the ferry, we followed along to the other side of this bay, the next step in the trek north. for all the people on that boat, this is the only way to the other side, a two-hour journey across the bay. so the boat's just arrived on the other side. and these are all part of the smuggling operation taking them from this boat to dry land. nelson and his family turned themselves over to a band of smugglers after negotiating passage along the only land route into central america. they are taken on dirt bikes, an hour ride through the countryside. your girl, how is she? okay. she looks a little scared, a little bit. >> si. >> reporter: to a smuggler's camp on the edge of the jungle. this is it. from here on out, it's all by foot, and it's all through the jungle. to reach panama, migrants risk robbery, rape, and death crossing the darien gap, a lawless 60-mile stretch of jungle considered one of the most dangerous in the world. at the camp, this smuggler told us roughly 600 people a day pass through, some dehydrated, hungry, and sick. they'd rather die trying to get to the united states than be deported to haiti. >> si. >> reporter: nelson and his family leave first thing in the morning. you're motivated. it's all heart. >> si. >> reporter: we're still waiting to hear whether they made it out of the jungle. manuel bojorquez, cbs news, necocli, colombia. >> o'donnell: well, still ahead on
