after allegedly posting classified material on a social media platform, prosecutors accused teixeira of smashing computers and a gaming console and telling others to delete all messages. the government says teixeira began accessing highly classified materials in february last year, and not all of it has publicly surfaced and has the capacity to cause additional exceptionally grave damage to the national security. the air force temporarily suspended two commanders of teixeira's unit and stripped them of their access to classified systems. further disciplinary action has not been ruled out. and today prosecutors suggested more charges are possible for tei teixeira, who already faces 25 years if convicted. norah. krathd rin, thank you. communities along the upper mississippi river are bracing as floodwaters continue to rise due to heavy rains and spring snow melt. five states including iowa, minnesota, and wisconsin are seeing some of the worst river flooding in two decades.

the doctor. dr. della ga release, a veterinarian with the u.s. fish and wildlife service is leading the effort to bring one of america's most endangered species back from the brink of extinct. >> who is this? >> this is turmeric. he's a little spicy today. >> spicy. >> reporter: spicy because the black-footed mil anesthesia. >> one liquid ferret. >> reporter: we were invited to help were physical exams ahead of breeding season. >> we've also got to check out the goods because -- and they feel pretty good. you know, they don't -- >> this is very important. >> it's a breeding program, right, so can't be shy. >> reporter: it was only a few days ago reproduction wasn't thought possible. the species was believed to be extinct due to habitat loss and disease.

but in 1981, the federal government tracked down the only known colony and started this breeding program with just seven ferrets. that makes turmeric. >> one of the descendants of the few founders, the seven founders. very related to all the other ferrets. >> and very related can be a tricky thing in the genetic pool of life. >> yeah, absolutely. more diversity is better. then you're more prepared for things like clhangli otherwise. >> reporter: since 1991, more than 4,000 genetically similar ferrets have been released back into the wild, where they help restore balance to the ecosystem. but with suchll gene pool, disease could wipe them all out. that's where wildlife biologist robin bortener comes in. >> oh, so you're a matchmaker here? >> yes, i try to be the ferest matchmaker. >> reporter: and there's no bigger catch in this dating pool than elizabeth ann. >> elizabeth ann is a

black-footed ferret that was produced using interspecies somatic cell nuclear transfer cloning. >> reporter: in 2020, she was the first endangered species native to north america to ever be cloned using decades-old dna from a black-footed ferret named willa. >> so we're essentially looking at a carbon copy of a black footed ferret from the '80s. >> yes, correct. >> incredible. >> so in here are the cells of willa that have been frozen since 1988. >> so this is where it all began for elizabeth ann? >> yes. >> reporter: mar lus hawk is the curator of the san diego frozen zoo, the largest bank of living animal cells in the world. by collecting and storing all this dna, the frozen zoo is at the forefront of an emerging field -- de-extinction. there are more than 10,000 samples, everything from skin to feathers.

>> when i was freezing cells from the northern white rhino, there were 50 living. and then now there's 2 left. >> what does this container of vials represent to you? >> the future. the future of these species. >> reporter: barbara durant, the director of reproductive he savn estated 1 million extin mostly because of us. >> have we reached the point where something that was human-caused now can only be cured or corrected by humans? >> yes. >> really? >> if we disappeared, a lot of things would grow back, but some populations are so small or don't even exist except here that they would not be able to regenerate without us. >> reporter: and that next frontier in regeneration may come through cloning. when tissue cells are grown in

the lab and then transferred into a donor egg that's had its nucleus and dna removed, that egg then develops into an embryo which is implanted into a surrogate. the result? a cloned ferret pup lik elizabeth ann. and most recently, kurt, an endangered za volunteer ski horse who we watched practice courtship at the san diego zoo safari park. this de-extinction science got some wondering what about dna from species lost ages ago? >> we go in, and then we can estimate where the dna can be. >> reporter: at colossal biosciences in dallas, texas, this new tech company has raised hundreds of millions of dollars to bring back extinct species like the dodo bird, which died off in the 1600s, and the woolly mammoth, which was wiped out 3,000 years ago. >> i hear mammoth and dodo in

the same sentence. >> yeah. >> and, you know, it's science fiction. >> it is until it's not. >> reporter: ben lamb founded colossal sciences. he says the first cloned woolly mammoth could be born in five years and eventually reintroduced to its native tundra habitat. a dodo chick could take longer because we don't yet know how to clone birds. but -- >> if you're willing to accept something that is similar to a dodo in some physical way but not identical, we'll get there a lot sooner than if you want something that is exactly like a dodo. >> reporter: as paleogeneticist beth shapiro explains, an animal's dna starts to break down in the wild as soon as it dies. so there's no perfectly preserved dodo or woolly mammoth genetic material left. and, sorry, this is where we tell you that dinosaur fossils are too old to contain any usable dna.

but shapiro can still extract pieces of dna from bones she finds in the field. >> we will look at places where the permafrost, the frozen dirt where many of these bones are preserved is melting. >> reporter: the bits of dna are then extracted from those bones, sequenced in a lab, and used as a template for editing dna in the cell pz of the mammoth's close oat living resident, to create a creature approaching the real thing. >> why is de-extinction so exciting that it opens up the bank? >> people are attracted to the impossible or to what they see as impossible. would i like tow have seen $225 million invested into traditional conservation? yes. would i also like to see this money being invested into colossal so these new tools can be developed? absolutely yes. and that's where i see the real value of this technology. we can use these same tools to stop species from becoming like the mammoth. >> reporter: but the science may

take longer than expected. it was recently discovered elizabeth ann is unable to reproduce. >> during the procedure, we discovered that unfortunately her reproductive tract had not developed completely normally. >> reporter: but the work continues because the easiest way to save a species is to protect it before it's gone. >> a room like this, does this help with that battle? >> this is in many cases the only thing that's going to help. once the cells are here, they can be here indefinitely. so it's important that we get the cells now, and then we can work out the techniques for the future. >> that was jonathan vigliotti reporting. the overnight news is back from exti extinction in two minutes.

>> announcer: this is the "cbs overnight news." we begin with some breaking news here in washington. cbs news has confirmed that former vice president mike pence appeared before a grand jury investigating efforts to overturn the 2020 election. pence testified for more than seven hours about the events leading up to the january 6th attack on the u.s. capitol. special counsel jack smith wanted to know about pence's conversations with former president donald trump and trump's alleged role in plans to block congressional certification of president-elect joe biden's election victory. a federal appeals court on wednesday rejected trump's last-minute bid to try and block pence's testimony. cbs's robert costa is going to start us off tonight from outside the federal courthouse here in d.c. good evening, robert. and seven hours, that's a lot of testimony. >> reporter: indeed. good evening, norah.

former vice president mike pence at the center of the storm before and during the capitol attack. and today sources told cbs news he came prepared to tell the truth within certain legal bounds about what really happened behind the scenes in that relentless effort to get him to stop the biden presidency. special counsel jack smith got his star witness today -- former vice president mike pence, whose appearance before the grand jury was one former president donald trump repeatedly tried to block. pence's suv left the d.c. courthouse this evening after his lengthy session with investigators. >> usa! usa! >> reporter: trump, citing executive privilege, wanted to stop pence from sharing details about the days leading up to the january 6th attack. and trump's pressure campaign to overturn the 2020 election. >> will you, for example, be able to testify in your view about the private conversations you have had with president trump? >> people can be confident that we'll obey the law.

we'll comply with the law. >> reporter: trump leaned into pence privately and publicly on january 6th. >> i hope mike is going to do the right thing. i hope so. >> reporter: pence's refusal to block the certification of the election infuriated trump. now with pence moving closer to entering the race for the white house, his testimony today could affect the legal and political fate of his potential rival. >> there may be no better witness about what the president knew and was going to do and tried to do than the vice president himself. >> reporter: sources tell cbs news that pence prepared for this for weeks, talking with his lawyers about the chronology of key players, what they did, the memos they sent him, all to make sure he was ready for the questions from the special counsel. norah. >> robert costa with that breaking news at the courthouse, thank you. tonight we continue our look at crime in america with a focus on illegal guns. there's new data from the cdc that reveals 8 in 10 murders in the u.s. involve a firearm. as we are about to show you,

small changes to these weapons are making guns more deadly and the streets more dangerous. to see for ourselves, we went to the atf lab right here in the nation's capital. >> what kind of gun are we firing? >> it's a glock 17. >> reporter: this type of gun, on its own, is legal. but a simple device can make it more dangerous and illegal. >> explain what a glock switch is. >> so these are actually referred to as machine gun conversion devices. you can see some of these are mass produced metallic made and some of these are additive materials, 3-d printed. and this is what you'll hear referred to as a switch. >> reporter: the conversion devices are small and inexpensive. they cost as little as $20 but can change a handgun to fire 15 rounds in under two seconds. [ sound of gunfire ] >> these are both 3-d printed. >> reporter: these atf techs showed us how on a modified gun, one trigger pull is altered from this -- [ sound of gunfire ] to this -- [ sound of gunfire ]ald spyiul.

>> absolutely. especially out of a handgun, it's very hard to maintain a weapon that small with that amount of fire. >> reporter: commander lashay makal ran the metro police gun recovery unit and now oversees the seventh district. >> in your job, commander, how often are you seeing these now? >> we're seeing them with a degree of regularity. about 50% more than we saw last year. >> and that's because it makes this gun much more dangerous? >> absolutely. it increases the likelihood that we're going to encounter multiple victims when these are used. and also in those singular victim incidents, it increases the likelihood that those incidents will be fatal. >> reporter: the atf has seen a nearly 600% increase nationwide of modified weapons. and just last month, the mpd recovered a 3-d printer making illegal weapon parts. >> i think we understand at the police department that this is a nationwide issue. we understand that we can't arrest our way out of this.

we need assistance. >> reporter: d.c. police chief robert contee, set to join the fbi, says the justice ecosystem needs an overhaul to keep illegal guns from causing more harm. >> there have been more mass shootings in america in 2023 than there have been days. how much do you worry about a mass shooting in d.c.? >> it's something that's on my mind every day, while we're sitting here. you take, you know, one person with one firearm that's capable of shooting, you know, 100 rounds of ammunition very rapidly in a short period of time, you know, that can happen aany time. we see these converter switches that are able to convert semiautomatic firearms into fully automatic firearms. those are things that keep me up at night. the "cbs overnight news" will be right back.

>> announcer: this is the "cbs overnight news." let's turn now to that national security case involving leaked classified documents. a massachusetts air national guardsman accused of posting military secrets online. well, he appeared in court this afternoon. cbs's catherine herridge reports that federal prosecutors want 21-year-old jack teixeira to remain behind bars pending trial. >> reporter: wearing an orange jumpsuit, 21-year-old jack teixeira sat impassively, and his family left the detention hearing without comment. after his dramatic arrest this month, prosecutors allege

investigators found a gun locker in his bedroom at his mom's massachusetts home and weapons including rifles, ak-style weapons, and a bazooka. e nts cuse the whheld a to searchg abo mass kill at a buffalo supermarket, a uvalde, texas, elementary school, among others, and posted disturbing comments saying he wanted to, quote, kill a ton of people. five years ago, it's also alleged teixeira was suspended from high school for talking about molotov cocktails, guns, and making racial threats. >> given his alleged history, how did teixeira pass the background security clearance? >> the air force and the department of defense are also taking a look at security protocols and practices here. i think the short answer to your question is we don't know. >> reporter: teixeira's apparently threatening high school behavior was flagged to local police and nationally blocked him from purchasing weapons. but that changed after teixeira cited his position of trust in

the u.s. government. after allegedly posting classified material on a social media platform, prosecutors computers and a gaming console and telling others to delete all messages. the government says teixeira began accessing highly classified materials in february last year, and not all of it has publicly surfaced and has the capacity to cause additional exceptionally grave damage to the national security. the air force temporarily suspended two commanders of teixeira's unit and stripped them of their access to classified systems. further disciplinary action has not been ruled out. and today prosecutors suggested more charges are possible for teixeira, who already faces 25 years if convicted. norah. >> a lot of new information. catherine, thank you. communities along the upper mississippi river are bracing as floodwaters continue to rise due to heavy rains and spring snow melt. five states including iowa, minnesota, and wisconsin are seeing some of the worst river flooding in two decades.

"that's your version," tacopina responded. carroll: "those are the facts." carroll alleges the attack was violent and left her traumatized. she did not report it to police. in a heated exchange, tacopina noted carroll never screamed at trump during the assault or screamed for help. "i'm not a screamer," carroll testified, adding later in a raised voice, "i'm telling you he raped me whether i screamed or not." tacopina suggested carroll made the allegation publicly just to sell her autobiography, which was released in 2019. carroll denied that and said she came forward after women began sharing their stories during the "me too" movement. trump has repeatedly denied the allegations. in a statement, the communications director for

trump's re-election campaign called the civil trial a fake case and a witch hunt. >> this case is 100% revolving around the credibility of e. jean carroll. these nine jurors must believe her in order to find for her and award damages. >> reporter: e. jean carroll will resume her testimony on monday. now, that's the same day donald trump is expected to leave for a four-day visit to his golf clubs in scotland and ireland. norah. >> elaine quijano at the courthouse, thank you. courthouse, thank you. the "cbs overnight news" dove 0% is different. we left aluminum out and put unbeatable 48 hours freshness and 1 quarter moisturizers... in. dove 0% aluminum deodorant. instantly dry feel and kind on skin.
