captioning sponsored by cbs >> mason: the ground shakes, buildings fall, a powerful earthquake hits central mexico. the death toll is rising as the search goes on for victims. also tonight, potentially catastrophic hurricane maria takes aim at the virginiain islands and puerto rico. >> this is most serious storm in modern history in puerto rico. >> mason: at the u.n., president trump threatens to destroy north korea and its dictator. >> rocket man is on a suicide mission for himself and for his regime. >> mason: and is this the answer to school shootings: teachers carrying guns. >> reporter: do you have the

mindset to actually shoot a shooter, and what if it's one of your students? this is the "cbs evening news." >> mason: good evening. i'm anthony mason. a disaster is unfolding south of the border. a powerful magnitude-7.1 earthquake struck central mexico today, southeast of mexico city. panicked residents poured into the streets as buildings crumbled. many others were trapped in the rubble. they've just begun to count the dead as the frantic search goes on for lives that can be saved. we begin our coverage with addrienne bard in mexico. >> reporter: it began to shake at 1:14, and it felt like it would never stop. this one seemed like the big one. pictures and statues fell off the shelves at our home. we lost all communication via cell phones, landlines, and the

power wentute. elsewhere in the city, we learned of buildings collapsed. people are still trapped in the rubble. the roofs of a shopping center david in. the airport runway is cracked. a government building sits tilted on its side. many, many people are injured and even more still feeling panicked. everywhere you go, there are people on the streets and small piles of rubble. the quake was not as strong as one that hit exactly 32 years ago today killing 10,000 people, but the epicenter was much closer. we still don't know the full extent of the damage. we are getting word, anthony, that there are dozens of children trapped in a school which collapsed. there are rescue workers there, and just ordinary people, neighbors coming out on the street digging. we're just getting the full picture here. we don't know the extent of the damage. but as i walk down mexico's main

avenue tonight, reforma avenue, i can tell you there are thousands of people out on the streets gazing up at cracked buildings. >> mason: addrienne bard in mexico city. thank you, adrian. a news caster in mexico was on the air when the earthquake hit when the studio started shaking. he left quickly in search of a safe place. the station's cameras caught what was happening outside. and back in the studio, heavy lights shook wildly, a good reason not to be under pem thp dr. lucy jones is a renown seismologist who spent years with the u.s. geological survey. dr. jones, this was a smaller quake than the one that hit mexico earlier in the month, but it appears to be doing significantly more damage. >> this earthquake, it's smaller but it's closer to many more people. so where the 8.2 was offshore and at a depth of 40 miles down, this is only 80 miles from mexico city, and about 30 miles down and with a lot of people nearby.

proximity makes a big difference. >> mason: i noticed on twitter that you said that part of the problem here is that mexico city has what you called bad soil, that the soil in mexico amplifies the shaking. what do you mean? >> well, that's right. well, so, mexico city is built on an-- a dry lake bed. so there was a lake thereupon there. it dried out. it left behind these sediments that are very, very loose. and so when the seismic waves come through them, the loose soil slows them down, but they still have all that energy. so they have to get bigger to carry that loose soil. here in downtown los angeles, we have about a factor of five amplification because of soils. and mexico city, it's over a factor of 100 so that they have had huge damage, even from earthquakes that are hundreds of miles away. this one is much closer than the '85 earthquake that did so much damage. >> mason: dr. lucy jones, thank you so much for being with us. >> thank you for having me. >> mason: a potentially

catastrophic hurricane is heading for the u.s. virgin islands and puerto rico. maria is a category 5 with maximum sustained winds of 165 miles an hour. some caribbean islands in its path, including tortola, were ravaged two weeks ago by irma. roofs there were torn off, and at least five killed. now, they're defenseless as maria takes aim. david begnaud is in san juan tonight. >> reporter: just two weeks after hurricane irma sideswiped the islands, the governor walked through the streets today making sure no one was taking any chances. "please, let us help you," ricardo rosello told his family. irma walked out pour here and in 70% of the rest of island including the home of hector pena-gomez. he is bedridin with parkinson's disease. "we're going to do our best to take you to a safe place," the

governor told him. the fear here is fueled by dominica and guaynabo. tortola is bracing for the worst. where to take shelter on an island where almost every building was damaged and the roofs ripped off? storm debris from irma could be turned into potential lethal missiles as maria's winds move in. in puerto rico, food is being rationed. there are lines to buy fuel and to get into shelters. are you going to get out. >> yes gl this woman is headed for shelter after her generator broke upon her daughter cannot sleep in the insufferable heat as a monster hurricane approaches. most places are boarded up tonight as the wind is picking up. you know, the last time a category 5 hurricane made landfall here was 90 years ago. maria is expected to hit tomorrow morning early. anthony. >> mason: eric fisher is chief

meteorologist at our cbs boston station wbz and he has the latest. >> hurricane maria has a very tight core, meaning the winds, the most destructive ones are right around the eye, but that eye bearing down on st. croix, as well as puerto rico, as we head into early on medicine morning, just before daylight, crossing the island as a catastrophic hurricane. after that, it tracks off to the north and west, just to the east of the turks and caicos, and find a spot off the eastern seaboard as we head into the end of the weekend. >> mason: eric, thanks. president trump made his debut before the united nations general assembly today. he told the leaders of the world he will always put america first and said they should put their countries first, too. mr. trump vowed to work with them for peace, but threatened to wipe one nation off the face of the earth. major garrett was there. >> the scourge of our planet today is a small group of rogue regimes will that violate every principle on which the united nations is based. >> reporter: president trump

warned world leaders that iran and north korea must be stopped. he said the u.s. is not afraid to use military force if necessary. >> the united states has great strength and patience. but if it is forced to defend itself or its allies, we will have no choice but to totally destroy north korea. >> reporter: the president then used his newly coined nickname for north korean dictator kim jong-un. >> rocket man is on a suicide mission for himself and for his regime. >> reporter: the president accused iran of financing terrorism in the middle east and repeat calls for the world to unite against islamic extremism. >> we will stop radical islamic terrorism because we cannot allow it to tear up our nation and, indeed, to tear up the entire world. >> reporter: mr. trump also implied he might pull out of the obama-era deal to halt iran's

pursuit of nuclear weapons. a decision to renew the agreement is due next month. >> frankly, that deal is an embarrassment to the united states, and i don't think you've heard the last of it. believe me. >> reporter: closer to home, mr. trump called cuba and venezuela failed socialist states. he said venezuela has descended into chaos after illegitimate elections. >> we are prepared to take further action if the government of venezuela persists on its path to impose authoritarian rule on the venezuelan people. >> reporter: not surprisingly, the president's u.n. speech highlighted divisions in the middle east. israeli prime minister benjamin netanyahu called it the most courageous and bold in 30 years. iran's foreign minister called it hate speech, better suited for medieval times than the 21st century. anthony. >> mason: major garrett, thank you, major. long before the special counsel began investigating russian meddling in the u.s. election and whether anyone in the trump

campaign was involved, paul manafort was the target of an f.b.i. investigation. it included electronic surveillance of the one-time trump campaign chairman. here's jeff pegues. >> reporter: cbs news has learned that the surveillance on paul manafort occurred during last year's presidential campaign. according to a former u.s. official, the intercepts picked up conversations between manafort and russian individuals about the campaign. the intercepts potentially include conversations between manafort and mr. trump. the recordings are now part of special counsel simon simone ros investigation, which appears to be intensely focused on manafort. >> i have answered questions and i've been dismissed. >> reporter: just last week, manafort's spokesman, jason maloni appeared before a grand jury. in july, agents raided manafort's condominium in virginia by reportedly picking the locks to get in while he was

asleep. how would you characterize what you see happening with paul manafort? >> very aggressive. >> stephen swrieden berg say former federal prosecutor. he said investigators may be pressuring manafort to give up information in exchange for leniency. what do prosecutors do to pressure someone to cooperate? >> doing exactly what they're doing now. >> reporter: swawrnts. >> swawrnts, interviewing everybody around him, and then advising him that he's about to be or will be indicted. >> reporter: in a statement, a spokesman for mr. manafort called on the department of justice to "release any intercepts involving him and any non-americans," claiming that "there is nothing there." manafort has been under legal pressure before. in 1989, he was accused of being part a scheme to steer millions of dollars to well-connected republican party operatives through a new jersey housing project. during a congressional hearing, the well-connected lobbyist was pressed to describe what his job entailed. >> you could character this as influence pedaling. >> thank you.

>> reporter: also today, senate intelligence committee leaders abruptly canceled a closed meeting between trump attorney michael cohen and committee investigators, scolding cohen for releasing a public statement in advance. the committee later invited cohen to appear at a public hearing next month. anthony. >> mason: jeff pegues, thanks, jeff. while the u.n. general assembly is in session this week, former new york mayor michael bloomberg is hosting a business forum for c.e.o.s and government leaders. among other things, i asked him today what he thinks about president trump's warning to north korea. >> there's no military option that is attractive where you can win. everything is going to be lose. it's just a question of how much. but the lesson of all of this is that you can't deal with a rogue state like korea by yourself. you have to have great, tight relationships with all-- or lots of other countries, particularly the surrounding countries. and, unfortunately, america is going in the other direction. >> mason: one of the first

things the president said in his speech today, which he often said, is the stock market at a record high. >> it's up today. >> mason: what is that a reflection of? >> i have absolutely no idea. i cannot for the life of me understand why the market keeps going up. our economy has some real challenges it's infrastructure is falling apart, we're destroying jobs with technology, we are keeping the best and the brightest from around the world coming to america to create new jobs and create new businesses. all of those things would give you pause to worry about the future. >> mason: you've said immigration reform is probably the most important issue in the u.s. u.s. how much do you think it's costing us? >> well, i don't know how you put a number on it. what is clear if you look at who starts new businesses, people that are innovate and i have risk takers. when you look at immigrants, you really have to be an innovator and a risk taker to leave everything you know in the old country and go to a new country.

people that come here come here to work. >> mason: if we slow immigration, restrict immigration. >> yes. >> mason: what's the price of that? >> we are hurting ourselves. we are hurting jobs. we have less business, less business formation, less new ideas. >> mason: you're afraid we're falling behind? >> not afraid. we are. you think about china. china used to be "made in china, a joke. cheap stuff. i didn't want to use it." today, "made in china," quality. >> mason: you think they're doing it better than we are? >> in some places yes. i still think there's no reason we have to fall behind unless we stop reaching out to the world, bringing the best and the brightest here, building good trading relationships with everybody. and you can't do it alone. >> mason: have you had any regrets at all that you chose not to run for president? >> no, i think it would have been a great job. i would have loved the challenge. i don't think there's any question about that. but we did the work and we decided in the end an independent cannot win.

>> mason: does that mean you won't run again? >> i joked that i'm going to run for the president of my block association. >> mason: former new york mayor michael bloomberg. coming up next on the cbs evening news, teachers arming themselves to try to stop school shootings. diet and exercise, once-daily toujeo® may help you control your blood sugar. get into a daily groove. ♪ let's groove tonight. ♪ share the spice of life. ♪ baby, slice it right. from the makers of lantus®, ♪ we're gonna groove tonight. toujeo® provides blood sugar-lowering activity for 24 hours and beyond, proven blood sugar control all day and all night, and significant a1c reduction. toujeo® is used to control high blood sugar in adults with diabetes. it contains 3 times as much insulin in 1 milliliter as standard insulin. don't use toujeo® to treat diabetic ketoacidosis, during episodes of low blood sugar or if you're allergic to insulin. get medical help right away

>> mason: a group that keeps track of school shootings in america says there have been 240 since 2013, about one a week, including one last week at a high school near spokane, washington. some teachers believe the answer is to arm themselves. others strongly disagree. nikki battiste has been looking into this. >> drop your gun! >> reporter: this is the point of view of an elementary school principal, firing at a mock gunman during a simulated school shooting. he's one of more than 1,000 educatoreducators from 12 statee this three-day firearms course in rural ohio called "faster

saves lives." >> nicely done. >> reporter: he says hitting these targets is preparation for protecting his students. >> when i walk down the halls, i actually think about where would i go? how would i react? you remember you left something in your van so you're going to go to the van and get it and go back into the school. >> reporter: most here asked us to protect their identity, including this middle school teacher. she keeps her .9-millimeter handgun on her during class. do you have the mindset to actually shoot a shooter? and what if it's one of your students? >> you have to know the important thing is to eliminate the threat and do that at all costs. >> start! >> i'm going to kill you guys. >> reporter: instructors test participants on taking down a gunman and treating wounds. >> somebody is hurt over here! >> reporter: funded by a progun group, the training is free, gun after the sandy hook elementary school. abbeabbey clements' 19 students

survived, and now she is one of a dozen newtown teachers fighting to keep guns out of classrooms. >> never in a million years would i have guessed that one response to what happened in our town would be to arm teachers. it's absurd. god, you can imagine if more-- if children were hurt by you in that situation? how would you live with yourself? >> reporter: in fact, we saw just that scenario play out in this simulated classroom. during this training i saw one person shoot what would have been a more than this scenario. when you see that, does it make you second guess this choice to have guns in schools? >> no. it's an accident we might take one, but we might have saved 30, 40 other kids. >> reporter: who carries a weapon on them in their classrooms or in their schools? for this group, carrying a gun in school is optional. some parents don't know their child's teacher is armed, but

others do. for parents who might support this idea, if you could speak to one, what would you say? >> i would say that i understand that you're afraid. i am afraid, too. we have a problem with gun violence in this country. but more guns is not the answer. >> reporter: the director of the training we visited says all participants must pass the same firearms test required to become a police officer in ohio where they only need 80% accuracy to pass. but teachers in this training are held to 90%. so far, anthony, about 30 educators have failed. >> mason: nikki battiste making her debut on the cbs evening news. welcome, nikki, and thanks. >> reporter: thank you. >> mason: still ahead, toys "r" us borrows cash to make it through the holidays. endless fiber-- it could be wearing on you. tell your doctor what you've tried, and how long you've been at it. linzess works differently from laxatives. linzess treats adults with ibs with constipation or chronic constipation.

eliquis also had significantly less major bleeding than the standard treatment. eliquis had both... ...and that turned around my thinking. don't stop eliquis unless your doctor tells you to. eliquis can cause serious and in rare cases fatal bleeding. don't take eliquis if you have an artificial heart valve or abnormal bleeding. if you had a spinal injection while on eliquis call your doctor right away if you have tingling, numbness, or muscle weakness. while taking eliquis, you may bruise more easily... and it may take longer than usual for bleeding to stop. seek immediate medical care for sudden signs of bleeding, like unusual bruising. eliquis may increase your bleeding risk if you take certain medicines. tell your doctor about all planned medical or dental procedures. eliquis treats dvt and pe blood clots. plus had less major bleeding. both made eliquis right for me. ask your doctor if switching to eliquis is right for you.
