that lane graves died of drowning and traumatic injuries. his family released a statement which reads in part words cannot describe the shock and the grief our family is experiencing. we are devastated. now this is as the search for the gator involved in the attack continues. at least seven have been pulled from the lake, but so far peter no confirmation they have found the right one. back to you. >> thank you. that's going to do it for me for this hour. i'm peter alexander. my friend kate snow picks up our coverage beginning right now. and good afternoon, everyone. i'm kate snow. from the beginning, she has been a key figure in the orlando investigation. we now know before the rampage was even over police were knocking on noor mateen's door telling her to come out with her hands up. that's what a source close to the family is telling nbc news today about the wife of the shooter. part of a new trove of information in a difficult search for the truth. noor mateen has been cooperating

with authorities we're told. according to that source, she's revealing for the first time that she and her husband engaged in texting during the actual shooting. what they said in just a moment. also a new look at the gunman's childhood. were there warning signs as far back as grade school? public records show the gunman and his wife gave their apartment to omar mateen's older sister just two months ago. on the one-year anniversary of the charleston shooting today, the senate has set a date to vote on gun control measures. we'll have complete analysis of the ongoing political dialogue coming up in just a few minutes. we'll check in on charleston one year later, but we begin with the investigation into the orlando mass shooting. pete williams who has been following every development from washington, he joins me now. pete, we're learning a lot more about the wife's involvement. >> right. a couple of things that are

coming into a bit clearer focus, kate. we have heard from federal officials that before the shooting she and her husband bought ammunition, that she was with him when he bought some ammunition. we now believe that was not ammunition that was used in the shooting. what we've been told is that ammunition was purchased at a walmart. she has told the authorities, according to relatives, she was with her husband that night, that she was with their son in the toy section while he bought ammunition in the gun section. what we're told is that the ammunition that was purchased was .38 caliber ammunition. you may recall two guns used in the shooting. a .9 millimeter handgun and the assault rifle which took 223 ammunition. he had in the van a .38 caliber

revol revolver. the ammunition that he purchased when she was with him was not ammunition that was used in the shooting. secondly, we found this record earlier this week. there's more attention to it now. back on april 5th, her husband got a lawyer, went down to the courthouse, and signed what's called a quick claim deed. basically transferring the ownership of his apartment to his sister and her husband, his sister sabrina. that was done april 5th. why it was done i don't think authorities have a good answer to. obvious question, was he thinking he needed to get his affairs in order because he thought he would die in some kind of terror attack or was there a financial reason behind this or something else. we don't know the answer to that question, but those are among the sort of fresh details. >> and that is all very fresh coming in. can i ask about the ammunition that you say was bought at the walmart, but not used in the

attack? >> right. >> leads one to question was there something else coming. are authorities concerned maybe he was planning something else? >> well, it's possible that -- we don't know this for certain. he had a security guard job. he had a license to carry a gun as a security guard and a .38 caliber gun would be a common weapon that would be carried by a security guard. why he would be buying his own ammunition for a company provided weapon, i don't know. maybe he was doing target practice or something. i don't know. in any event, it's not ammunition that was used in the attack. >> and just quickly, we said we would tell people about these text messages were exchanged. what do we know about that? >> it now appears that he was communicating in all sorts of ways with all sorts of people during this pause. the bulk of the shooting police

told us happened when he burst into the nightclub at 2:00 a.m. the police attacked and forced him into a restroom inside the nightclub when there was a pause in the most serious shooting. in that pause, he talked to the 911 operator three times. he called a local television producer. he sent messages on facebook. he exchanged very brief text messages with his wife. the way it's been explained to us is that she texted him first and said, where are you. he said -- these are words to the effect of do you see what's happening. are you watching the news? she says, no. he says i love you. that's it. very short. >> pete williams keeping an eye on all of this for us. thank you so much. folks in charleston, south

carolin carolina, know the grief and the pain orlando is feeling today. one year ago today a white gunman killed nine people in the mother emanuel ame church. ♪ amazing grace how sweet the sound ♪ ♪ that saved a wretch like me >> clemente pinckney found that grace, susie jackson found that grace. >> ron mott is in charleston, south carolina, where the

victims are being remembered. you look back at that tape and another emotional day too. >> reporter: absolutely. that was a powerful moment at that service last year for those victims by president obama. he of course was in orlando yesterday to meet with all new families who are dealing with the pain these families have dealt with. while the headlines may shift from town to town, city to city, as we see these one after another, these mass killings, the pain remains. that's the message that they wanted to send around the country today, that there is still pain in this community. it's going to linger for a while. governor nikki haley was one of the speakers today. >> they did exactly what every one of us would do when someone different comes up to us. they pulled up a chair and they prayed with him. >> reporter: there's going to be another service today, another unity service. then after that service is over

they're basically going to hang out, having a mixer to try to continue the dialogue between people of all races. they want to make sure the lasting legacy of this tragedy here in charleston is whatever walls that were up on the day this took place have been knocked down, if not knocked down completely. the senate will vote on four gun control measures on monday following a 15-hour filibuster by democrats. hillary clinton tweeted this. one year ago we lost nine lives in charleston. 49 in orlando on sunday. 26 in newtown. too many others. this has to stop. we need to change. luke russert joins us from capitol hill. we have measures from democrats, measures from republicans. what can we expect? >> we're going to see four important gun votes taken. we'll start off with the democrats. they're going to put it forward

to chris murphy who led a 15-hour filibuster on the senate floor a few days ago. he wants to strengthen and close the gun show loophole, as well as strengthen checks on guns sold over the internet. that is expected to go down because the nra says licensed sellers at gun shows, they have to do checks. you're hurting private sellers to just make a buck on the side. the same thing applies with the nra's logic toward internet gun sales. the other thing the democrats are going to put forward is this idea of no fly, no buy. if you're on the terrorist watch list, you should not be able to purchase a gun. this is something that came up after the san bernardino terrorist massacre at the end of 2015. this was also voted down, but there is some commonality.

a republican's proposal is if you're on the terrorist watch list, you should not be able to purchase a firearm, but there are plenty of people on that list that shouldn't be on there and their rights are being infringed upon. give the doj 24 hours to prove their case, similar to what you do with an intelligence court. both sides agree there's a problem. you're going to see an amendment put forward by chuck grassley that puts more money into background checks and mental health, but he has an element if you've been on the terror watch list for the last five years, even if you have been taken off of it, you should have a gun sale flag. the killer from orlando would have been flagged this time around. i don't think background checks are going to go anywhere because the nra feels very strongly about that and they have

powerful allies here in congress. there is in theory a way for the terrorist watch list bill to become law if both sides are willing to give a little bit. maybe it's a three-day review for doj, maybe it's five days, maybe it's 50 days. democrats say the three days is too difficult. it's going to be interesting to see what these numbers are come next week, especially if those endangered republicans move away from where they voted in december. >> donald trump has even said that he favors some kind of way to restrict people on the watch list from getting weapons. what about the house? if any of this passes in the senate, it still has to go through the house of representative representative representativess. >> if there were to be a bipartisan compromise that would

come together on this no fly, no buy bill through the senate, unless it got really strongly support in the 70s, 80s and 90s, it would go over to the house and languish. that's why getting the support of the nra or we won't lobby against it is so important. that's probably they were going to work on in the next few weeks. >> thanks so much, luke. up next, we turn to politics. but first we need a laugh on a friday afternoon. jimmy fallon had a little fun last night breaking down a big point of contention between hillary clinton and donald trump. >> trump and hillary are really starting to go at it. today trump took a swipe at hillary and said he's not sure if she understands the difference between a wall and a fence. yeah, it's getting nasty. hillary is like, yes, i do. a wall is something you want to build.

a fence is the only thing keeping me from moving into the white house today. ents. a deluge of digital records. x-rays, mris. all on account...of penelope. but with the help of at&t, and a network that scales up and down on-demand, this hospital can be ready. giving them the agility to be flexible & reliable. because one knows & like at&t. ♪jake reese, "day to feel alive"♪ ♪jake reese, "day to feel alive"♪ ♪jake reese, "day to feel alive"♪

think back about three months. it was a little colder and all we could talk about was a contested republican convention. it seems like ages since trump was able to secure the number of delegates to clinch the nomination. today his campaign is down playing a rejuvenate d force of anti-trump forces. jacob, this afternoon reports that some of these anti-trump forces are looking for a way to prevent him from getting the nomination in cleveland. what's the campaign saying?

>> reporter: here we go again. a campaign strategist says they're not taking it too seriously. one adviser says the campaign believes they have enough delegates on the rules committee to make sure nothing crazy gets through, but the delegates we're talking to said they have a last-ditch effort. these are people who are reluctant in the first place, but now they say it's a matter of conscious that they have to come in and they have to find a way to make a change in the rules so that if somebody, because of a matter of conscious, feels like they cannot vote for trump, they should be unbound. they have in 25 to 28 states different representatives going around trying to coordinate this. they have a few dozen delegates on board so far. they would need a majority of delegates on the rules committee

to get any sort of vote there. it would have been to be ratified in the convention. it's a big long shot. we saw this sort of language from paul ryan where he was giving the permission to vote their conscious. we heard similar language from mitt romney. if you're not going to run, why are you coming out and talking about trump this way? he said it was a matter of conscious. whatever percentage or chance there is that any of this could actually happen, these are for those who are efforting these different efforts, for lack of a better word, a matter of conscious. it is just one more effort like that. i'll just end on this. this person who is organizing the effort says they have no clue what they would do if trump weren't nominated. >> jacob rascon down in texas. jacob, thanks. donald trump pretty sure to talk about one of his most

common campaign promises tonight, a temporary ban on muslims entering the u.s., but is that even constitutional, i say, as i sit down with ari melber who has had a chance to speak with one of the top attorneys in this country. you got an exclusive interview. >> a lot of people have waited on this. i was able to sit down with the u.s. solicitor general who knows what goes on in the minds of those justices. he's argued all the major cases of the obama era before him and i asked him about this muslim ban. >> and you mention immigration. when people look and say, oh, well, you've got a nominee proposing a religious ban for immigration. legally, constitutionally, would that power exist? >> i'd be surprised. i'd be surprised to think that it would. >> you think a supreme court would likely strike down that kind of -- >> you don't want to speculate on a case that doesn't exist and probably will never exist, but i

can't imagine the court would find a religious test like that appropriate. >> you use the word religious test because that itself is banned in the constitution? >> in that context, yes. >> he represents the president. >> the u.s. >> what does he say about the work he's had to do? >> he's had so many big cases, defending obamacare twice, defending marriage equality. he's really seen it all. these arguments are long and they can get complicated. to keep it simple, i tried to press him to give me one word answers on a bunch of these issues during his tenure. take a look. >> citizens united. >> unfortunate. >> bush v. gore. >> no comment. >> president obama. >> heroic. >> chief justice roberts. >> fair. >> justice scalia. >> brilliant. >> senator ted cruz. >> don't know senator ted cruz, so i'm not going to come up with

one word. >> never heard of him? >> not going to come up with a one word on him, sorry. >> your name. >> blessed. >> marriage equality. >> about time. >> so interesting. i love that he said fair about thomas roberts and brilliant -- i'm sorry. thomas roberts is our friend here. and he said brilliant about scalia. he is often on the other side. >> i said who asked the hardest questions. he said justice scalia was the hardest to back and forth parry with. bernie sanders moving on. well, sort of. he's staying in the race, but shifting his focus to donald trump now, telling his supporters he vows to work with hillary clinton to defeat the gop's presumptive nominee come november.

the major political task that together we face in the next five months is to make certain that donald trump is defeated and defeated badly, and i personally intend to begin my role in that process in a very short period of time. >> bernie sanders zeroing in on his general election target, donald trump. he did not drop out of the race, but in a video message watched live by thousands last night, senator sanders hinted that democratic party unity is around the corner. >> it is no secret that secretary clinton and i have strong disagreements on some very, very important issues. it is also true that our views our quite close on others. i look forward in the coming weeks to continue discussion between the two campaigns to make certain that your voices are heard and that the democratic party passes the most

progressive platform in its history and that democrats actually fight for that agenda. >> on the other side of the aisle, republican unity becoming a bit more elusive. more gop officials backing away from their presumptive nominee with permission from paul ryan. >> do you think that members in the house republican conference follow your conscious? >> absolutely. the last thing i would do is tell anybody to do something that's contrary to their conscious. of course, i wouldn't do that. believe me, chuck, i get this. this is a very strange situation. this is a very unique nominee, but i feel as a responsibility institutionally as the speaker of the house i would not be leading some chasm between the

party. >> rick tyler is with me now. rick, you heard the words there from paul ryan. the last thing i would do is tell anybody to do something contrary to their conscious. today we hear from a colorado delegate to the republican convention using that same term, saying he wants a conscious clause at the republican convention whereby delegates could choose not to vote for trump, even if they were not bound to trump. it's not an accident we're hearing so many people say conscious. >> first of all, the idea that we're having a discussion about voting your conscious at the republican nomination convention shows you how problematic the trump nomination is and has become and probably will continue to be. the problem with this idea though is that you can't beat something with nothing. you can't just say everybody vote their conscious and not

have a specific alternative which the delegates will rally behind. that's going to result in nothing because most of the delegates there, by virtue of winning the nomination, will be for donald trump. unless there's an alternative people can look at and say this is who i would choose over donald trump, it is just not going to work. >> hillary clinton spending $17 million in eight states. donald trump spending zero in those state. he has a big fundraiser next week in new york city. what are the finance folks saying? are they confident trump can get the money he needs to really run a strong election campaign? >> look, i brought this up about three or four months ago on this network. if donald trump is going to self-fund, i didn't believe he had the liquid cash to do it. who is going to pay for all this? i do believe donors will show up

at his fundraising events, but it remains to be seen if they'll write the checks. >> does he need that or can he just do it with free media? >> no, that party is over. if you look at media coverage in the last two weeks, donald trump is not calling into the morning shows this morning. he's not getting the type of reception he was getting on cable news and network news. they would take him and then he would get out his message. thanks for calling in. that ship has sailed. there has to be an alternative for him beyond earned media. he has to raise money. he has to raise money for the republican party for not just his race, but the senate race and the house races we need to protect all the way down to the state legislatures. >> the former president george w. bush is going to be out

campaigning down ballot. is there a great concern for party leaders that the down ballot races are going to have a lot of trouble? >> oh, it's huge concern and a particular one. you're going to have very close and contested races at the top of the ticket. a down ballot is predicated on who turns out on election day in presidential years. s -- it remains to be seen if people are going to turn out for hillary clinton, for donald trump. >> i've got to ask you on a friday afternoon one question about the vice president's strategy. everybody is talking about who would be the best choice for donald trump. is there anybody out there who's going to love getting that phone call, i want you to be my vp? >> getting vp is hard to resist.

historically, it hasn't made a whole lot of difference. it is usually a couple day news cycle. i thought the idea on doubling down on who you are makes sense. bill clinton picked al gore. people criticized that, but it worked well. i always thought newt gingrich would be smart because he would bring military intelligence and foreign affairs experience. >> but he's not an outsider. >> no, newt has migrated to being an insider, but he's always been an outsider. he overthrew a sitting speaker of the house. he rallied the republicans to win the republican majority he knows how to get things done in the congress. he got a lot of policy initiatives passed while bill clinton was president. there's a lot he could add to a trump presidency were that to pass. we have a very special

carrying out air strikes that have been targeting moderate rebel groups. some of them backed by the united states. while the united states has been focused primarily on the fight against isis, assad's forces have been launching a very aggressive campaign. and these people at the state department think that the u.s., specifically president obama, has walked away from the mission of assad must go and instead is focused on isis must go. well, assad, i guess, can stay for now as the lesser of two evils. people at state department feel that is basically a bargain with the devil. >> a memo signed by diplomats is known as a cable. the state department spokesman john kirby responded. he said, quote, we are aware of a dissent channel cable written by a group of state department employees regarding the situation in syria. we are reviewing the cable now. how much influence do these

dissent cables have in the first place? >> reporter: well, probably not very much, which is why the people who wrote this decided to leak it quite broadly to the media. this story appeared in several major newspapers this morning. newspapers that also have a great deal of influence in washington, "the new york times," washingt"washington po,l street journal." people can write opposing views, but if they thought it was going to have much of an impact, i don't think they would have taken the lengths to have leaked it, which is obviously a step that the state department wouldn't have wanted. which is why they opened this dissent channel in the first place so people wouldn't feel they would have to leak it. >> is there discussion going on within the administration about any change in policy?

>> reporter: i think the discussion right now has been focused on today after this leak, after these 51 people took a step to oppose the policy that they are to inform and to implement. it is a courageous move one could say. in the newspapers and on cable television, there's been a lot of discussion. whether this will change policy, however, seems unlikely at this stage. if you listen to the state department briefing today, there was a lot of dancing around the issue. we're not going to talk about changing policy. it's too early to say that. we appreciate all kinds of debate. i'm sure they don't appreciate these kind of leaks, but they gave the standard line of how the more dissenting voices are showing what a great democracy there is. obviously no organization wants to see leaks. no organization believes that having things leak out internally is good for the process.

>> richard engel in istanbul, turkey tonight. a crushing blow today for russia's olympic hopefuls. the world governing body for world track and field has banned the russian team from all international rio. >> although good progress has been made, the iaaf council was unanimous that rousseff had not met the accreditations and the russians could not return to international competition without undermining the confidence of their competitors and the public. rousseff has not been reinstated to membership of the iaaf. >> that being the governing body of track and field. what do these decisions mean? >> reporter: well, it means that after months of lobbying by

russia, including by president putin, they've failed to prove they can present clean athletes to the olympics. back in 2012, the russian track and field team won 18 medals. those, i guess, medals are now up for grabs, if you like. it means something pretty profound for world athletics, world track and field. because in the end for them to admit they can't let a team like russia compete in rio because they cannot trust them on doping is pretty embarrassing. >> for individual athletes, you can imagine the people whose dreams are going to be crushed by this decision. if there's an athlete out there, is there recourse for an athlete who says i'm clean, i want to compete? >> reporter: the athletic officials left some space for that. they say individuals who have been training outside of russia

may be able to compete, including one who was a whistle-blower. that will annoy russia even further. there's a meeting of the international olympic committee next week. they may decide to overturn this decision, although that would be pretty stunning. they may let other russian individuals compete. >> thanks so much. coming up, after a 2-year-old was dragged to his death by an alligator, a direct response from disney news this hour. alligator warning signs will now be posted. there's more to it than that. we'll break down two important medical stories coming up. an investigation into kids getting prescriptions for powerful mind-altering drugs and zika fears. three babies were born here in the u.s. with defects caused by zika. the economy is growing, with creative new business incentives, the lowest taxes in decades, and new infrastructure for a new generation

and more signs warning people about the potential dangers after the death of 2-year-old lane graves. all disney beaches remain closed this afternoon. the company conducting a full review of their protocols. we have been covering this story since it happened. when we're talking about fencing, i heard you say that last hour, so many of us have been to this lagoon right outside the park. what are we talking about? what kind of a fence and where? >> reporter: the fencing right now is being set up along the water where this attack occurred. we want to give you a first look of it. it is a 4x4 post drilled into the sand. then they're using rope to create a fence. in the past few minutes, they just began adding those new signs, which reportedly say beware there are alligators and snakes in the area. this comes disney's announcement they're going to review their

policies and procedures following this attack. for people in florida, it's a known fact, but for people visiting from all over the world they may not be aware of the danger. in fact, across the state of florida, alligator trappers are sent out to remove what are describes as nuisance gators. last year they removed more than 7500 of those gators. meanwhile the family of that little boy who was killed, 2-year-old lane graves, they have released a statement that says, words cannot describe the shock and grief our family is experiencing. we are devastated. kate? >> all right. thanks so much. after the break, an urgent caution for parents whose children may be taking prescription drugs. trolling for a gig with braindrone? can't blame you. it's a drone you control with your brain, which controls your thbs, which control this joystick. no, i'm actually over at the ge booth. we're creating the operating system for industry. it's called predix. it's gonna change the way the world works.

millions of kids take psychiatric drugs often for things as common as adhd, but

how much do doctors really know about them. for a report airing tonight on "dateline on assignment," we investigated off label prescriptions for children. that's when a drug is prescribed by a doctor to treat some other condition. we zeroed in other condition. we zeroed in on atypical psy psychotics. when he was 14, a doctor prescribed an anti-psychotic called sarah quell, off label, and andrew died from a rare side effect. >> you are a pharma guy, helping cell pharmaceuticals and increase access to pharmaceuticals and your own son dies of -- >> side effects. >> it's the ultimate irony. >> it's part of what i agonize over when i thought, how could this have happened to me? >> steven started digging and discovered something.

his son was one of hundreds of thousands of kids taking drugs that, it turns out, doctors may not know much about. that anti-psychotic, seroquel, it was not approved at that time for kids, only for adults. his doctor had prescribed it off label. >> about 1 in every 80 or 85 kids are receiving an anti-psychotic sometime during the course of the year. >> columbia university professor dr. mark olafson is a leading researcher on anti-psychotics and has documented how often kids get them for unapproved uses. >> is it safe? >> well, there are some safety concerns with these medications. many of them result in weight gain, they can increase cholesterol. and there are longer term things that are hard to study. we know less about the effects of these drugs on the developing brain. >> joining me now, dr. natalie

azar. nice to see you. >> and you, kate. >> i've done a lot of research on this, but let's talk about off label for kids. because sometimes off-label can be really helpful and the doctors are trying to do something that helps? >> no, no, right. we do use off label drugs a lot, we have to, because it takes a long time for drugs to get approved by the fda, but in this case, a few points need to hit home. and that is that you never treat children as little grown-ups, right? so it's very difficult to take a drug that's used in adult and just extrapolate and use in children, i'm not suggesting that anybody is doing that, per se. but if you really look at the review of this topic, very few medications that are off label, have been directly compared head to head with on-label use in terms of efficacy, safety, tollerability, all these questions that know haven't been answered for many of these drugs in children. >> one of the things i was most

surprised by, the fda in all this, you would think they're regulating everything that's happening. not really. they approve a drug and put it out there, but they don't have control over doctors and who is prescribing it to whom. >> no. again, if you look at it on the positive angle, most of us who treat patients with complicated diseases, we borrow drugs from other diseases that we know. let's say the mechanisms of the two diseases are very similar. >> right. >> and when drugs are used off label, we usually have phase two, phase three trial data that looks promising for a particular drug. it's nususually not a, oh, let' try this scenario. >> in your field? >> in my field. the stakes are always higher with children, especially with using medicines that request have psycho tropic effects on the brain. it's not the same as in adults. >> and we have news today about

zika, three cases of babies being born with birth defects linked to zika virus. it scares the heck out of people. what do we do? >> these are all cases that have been brought in or imported from ab aabroad. there have been positive blood sample screenings in puerto rico. people should be aware there's no federal mandate to screen u.s. blood banks in terms of donations. the only place that's doing it right now is in houston. encouragely, that i tested 9,000 samples since the outbreak began, and not one has tested positi positive. they're asking for travel history and they're not letting them donate if they have traveled. >> you can see my full report on nbc tonight, 10:00 eastern, 9:00 central, and we'll be right back.

a new feature coming to iphones, olivia stern joins us on controversy surrounding this new feature. we're talking about tagging automatically. how does it work and what's the controversy? >> apple just announced an update to their photo software. what it's going to do is similar to what google and facebook do. going through your photos and recognizing your friends and that is raising some legal concerns. the issue, look, they found our pictures. the issue here is that the way facial recognition software works, it builds a face print, and a lot of people say that's similar to a fingerprint. so right now, google and facebook are already being sued for this facial recognition software. the suits claim by building these face prints, you're violating the illinois biometric information privacy act that says, before you give over

fingerprints, eye scans, you need to give people more notice and get more consent. they're saying you're getting this personal information without getting consent and that's raising concern. >> as a public person, this scares me. when i'm out with my kids in public, i don't want everybody to be taking a picture and identifying me. >> right. it's important for consumers to know this exists and regardless of what happens with the suit, you need to start asking questions about the way your biometric data is stored. apple will say these face prints will be on your phone, it will be kept locally. google and facebook, theirs are stored in a cloud. apple will say theirs is more secure. but it's worth asking all these questions about the way your biomet rick data is concerned. >> appreciate it. breaking news, nbc news has confirmed surveillance video

from inside the pulse nightclub, this was taken on the night of the shooting and this video has been recovered and much of the massacre was reportedly captured on video. it will not be released, but we know that the video does exist. it could help authorities answer some of the lingering questions in that investigation. more on that in the next hour. that's going to do it for me this hour. i'll see you back here on "nbc nightly news," 6:30 p.m. eastern time on sunday night, and now, time for the road warriors. >> the major political tasks that together we face in the next five months is to make certain that donald trump is the defeated and defeated badly. >> and i said, that's only because of me, it is. it's only because of me. it's only because of me. it's only because of me. >> and the last thing i would do is tell anybody to do something that's contrary to their conscience. >> not one of donald trump's
