good morning. breaking overnight. mass casualty shooting. [ shots fired ] >> a horrific scene inside a popular gay nightclub in orlando when a gunman walks in and opens fire. approximately 20 people are dead, dozens more managed. >> i took my bandanna off and tied it and put it in the hole to make sure whoever tied and and put it in the hole whoever was coming to help us could help him. >> the shooting becoming a hostage situation. s.w.a.t. teams storming in to save at least 30 hostages and killed gunmen. this morning the violence being investigated as an act of domestic terrorism. >> absolutely, we are investigating this from all parties perspectives as an act of terrorism. >> this morning the horror and

full scope of the shooting still unfolding. to a scene of mass violence here is the latest. orlando police say approximately 20 people are dead and 42 are injured after a gunman walked into a popular gay nightclub called pulse. some running from the scene and others held hostage inside. the gunman has not yet been identified, but we do know he is dead, killed by police. investigators again, describing a hostage situation and that's when they moved in. authorities say the gunman was armed with an assault-style rifle, a handgun and some sort of device on his person. the fbi saying this will be investigated as a domestic act of terror. we have this in orlando with nbc's sarah dallof. >> reporter: good morning. a tragic scene in downtown orlando where authorities say the shooter entered the nightclub and exchanged gun fire with a uniformed orlando police

officer who was working in the club off-duty. the shooter retreated back inside the club and that is when he took hostages. >> we were being contacted by people in the bathroom, nearby, at least 15 people that were in a separate area and our biggest concern was future loss of life. we wanted to save those people so we did an entry and exchanged gun fire with the suspect again after some explosive devices were used as well as our bear cat was used to get through the wall. >> reporter: the suspect was shot and killed. an orlando police officer also shot. however, officials say that his kevlar helmet did save his life. as this was all unfolding people in the nightclub who were able to escape were helping others and helping treat the wounded.

>> we were across the street and you could still hear the boom, boom. it had to have been more than one person or two it was just too con tin wows. it was as if you were in a gun range and all you hear is just boom, bang, bang, and it was just -- i can't even describe it. it was -- i am, but it was really difficult to see in real life a horrible situation. >> did people realize what was going on? >> no. i don't think people really knew what was going on until they saw people on the ground bleeding and heard people screaming because you don't know. when you're in a bar like that, you really think there are music and there are three different places and playing three different music and there are sounds on the patio, inside the main area and another area where they were dancing, the go-gos. and three different types of music playing at the same time so you don't know what's what.

>> reporter: 42 people were taken to area hospitals to be treated and this morning we are seeing survivors loaded on to city busses and taken to the police station to give statements. meanwhile, officials say they do not believe there is any credible threat to the city of orlando this morning, but a lot of shock and a lot of sadness here, willie, back to you. >> sarah, you are listening to the eyewitness account and pulse nightclub posting around 2:00 in the morning and local time in orlando on its facebook page, everyone, get out of pulse and keep running. what else did you hear? you've been on the ground for several hours from people streaming out of the club, many of them running for their lives. some contacted police and loved ones trapped inside bathrooms waiting for this to pass. >> reporter: and that is the most difficult part for people right now, the waiting. i met with one young man who had fled the nightclub, but he'd been separated from his friend

during his escape. he had been calling her repeatedly and not able to reach him and willie, he kept saying you don't understand, you don't understand, the bodies, the bodies. so people are trying to process what they've seen. they're trying to track down their friends and loved ones inside the nightclub who they haven't been able to get a hold of. just a horrifying situation all around. >> we'll let you get back to some of your reporting and by the way, you're looking at a live helicopter shot overhead. approximately 20 people are dead. they don't have that number exact yet, but as much as they were willing to say, publicly, approximately 20 dead and 42 more victims transported to area hospitals. this happened at 2:00 in the morning when a man walked into the club with an assault-style rifle and a handgun when he was engaged by a police officer who was working security at the time and that exchange of gun fire turned into a three-hour hostage situation at 5:00 local time

orlando police said the decision was made to send in the s.w.a.t. team and to engage the shooter at which time he was shot and killed. let's go to jim cavanaugh, an nbc law enforcement expert. jim, good morning. we heard in this press conference the sheriff saying this was being treated as an act of domestic terror, but then we have the fbi saying we look at this as terror in some form, but they're not willing to go that far yet. as you listen to them speak about this crime, what did you hear? >> it looks like the motive might be domestic terrorist related, in other words, hate and targeting of a minority, the lgbt community. maybe this was latin night, the latin community because this is an unusual target for an internationally-inspired actor late at night. we did have the bataclan in paris, willie, but that was an unusual situation there. this is not the typical target of internationally-inspired

terrorists. when they're saying it's terrorism and turning it over to the fbi as the lead, they have some indicators that this was targeted for this particular club and he came with the assault rifle, as you described. that's why we have so much carnage inside there because the velocity out of those rifles is awful and so you have 42 wounded and maybe 20 people killed. if it wasn't for orlando p.d. who bocked them up and keeping them static until s.w.a.t. could get to him and with the explosive entry and the bear cat, it could have been even worse. we could have had lots, lots worse killing in here. >> this was a coordinated effort between state and local police that started at 2:00 in the morning in orlando, jim. what would have been the protocol there. it turned into a hostage situation and over the course of three hours they decided to at 5:00 in the morning to send in the s.w.a.t. team. what was the decision to send in s.w.a.t.

it's the on scene tactical commander, in this case it was s.w.a.t. and they'll make the decision reading the escalation and de-escalation of the event and whether they can stay negotiating or they've got to make a move, and the chief said they have to make a move to rescue people, 15 or 30 that were in a bathroom and they used explosive entry. they used a bear cat armored vehicle and they punched in there and engaged the subject when he came out in the hallway and s.w.a.t. officers are well trained, great shots and they were able to take him out, but he wounded one of the orlando p.d. officers and hit his helmet and maybe hit his eye slightly and they were able to stop the killing to make the entry at that time. >> we don't know the exact layout of the nightclub, jim, but you look at that space. 320 people in a relatively tight space, a shootout in there would have had huge ramifications and has this morning and the decision to engage him, pretty

quick, i would imagine. >> it's hard to get to the killer before he pulls his trigger first. it's hard to get there before he does that, but orlando p.d. had an officer in there working an extra job and he heard gunshots and by then he might have unloaded a magazine into the crowd and then there was a gun battle and then more shots. so, yeah, it's an awful, awful case and tre will be a lot of heartache in orlando tonight. >> the suspect walked in, quote, prepared and well organized. we're getting new tape, jim. i want you to listen along with me of the sounds of gun fire early this morning in orlando. let's listen. [ gun fire ] >> jim, we don't know exactly what time or at what stage of the operation that was, but obviously, automatic gun fire there. what did you hear? >> that's a gun battle because you can hear the guns -- the

rounds going each way. so that's the police engaging the suspect at some point in the event. rounds going each way. >> so, jim, as we look at this now in the bigger picture where will the investigation go? again, domestic terrorism is how it's being investigate according to thor sheriff's office. the fbi saying there's no suggestion at this moment of a further threat to the city of orlando or to anyone else, but they will be looking at this as an act of terrorism first. how do they proceed with this investigation as we sit here this morning? >> very large forensic footprint. they'll go really slow through that scene, probably today, maybe a couple of days a very aggressive white collar investigation going on right now by the detectives and agents. basic 101, you will get the guy's wallet and cell phone and see who he is and why he's there and then you will get to his car at the scene and make sure he doesn't have bombs and explosives and you'll get to his house and apartment and see what's there.

you'll get on his computers and why did he do this and he'll have it written down and his motives will be there and they'll be clear and they're going to uncover that and then, of course, the thing -- is there anybody else planning it with him, helped him, encouraged him, facilitated with him or is planning yet another attack. >> that's an important point. police saying at this point, eyewitnesses gave no account of a second gunman. that's according to eyewitness account. it was just the one suspect. jim cavanaugh, stick around, i'm sure we'll be back to you. >> a recap, so far, approximately according to police 20 people dead at least 42 others injured. the gunman killed by police after taking dozens of hostages in a three-hour standoff. police were able to save, they say, as many as 30 hostages. we'll have much good sunday morning to you. starting off mild in most parts of the bay area.

we're back on a sunday morning following the breaking news out of orlando. orlando police saying approximately 20 people killed. they don't have a definite number, that's their terminology, approximately 20 killed. 42 more taken to local hospitals after a gunman opened fire inside pulse nightclub there in orlando. let's go back to orlando police chief john mina talking about a

hostage situation that developed beginning at 2:00 in the morning lasting until 5:00 a.m. eastern time there in orlando when a s.w.a.t. team went in to engage the people. >> we were being contacted by people in the bathroom, nearby, at least 15 people in a separate area, and our biggest concern was future loss of life. we wanted to save those people so we did an entry and exchanged gunfire with the suspect again after some explosive devices were used as well as our bearcat was used to get through the wall. >> let's bring in nbc analyst former fbi profiler, clint van zandt. he's on the phone with us. clint, good morning again. let's talk about what we heard in that press conference from local police, the sheriff's office, federal authorities as well about the decision to go in with the s.w.a.t. team. again, a hostage situation that developed when a uniformed orlando police officer engaged the shooter who was armed and well prepared according to police. he had an assault-style rifle and a handgun but the hostage

situation lasted three hours. as you've dealt with these situations before, clint, talk with me about the decision to send in s.w.a.t. >> as you know, willie, part of my background is as an fbi hostage negotiator and i've been involved in these decisions before, whether to go tactical, send in s.w.a.t. obviously the first thing that law enforcement would rather do would be to get a hostage negotiator and talk the shooter out, get him or whatever we have to lay down their weapons and surrender. if at the same time you're doing or attempting to do negotiations and yet you're getting information from inside that there are shots still being fired, people still being injured, then law enforcement is moving toward that tactical resolution. but we don't have s.w.a.t. teams on the scene all the time, even though i'm sure there were a number of patrol officers ready to go in. s.w.a.t., that's their job, their full-time job. so a decision was made to get s.w.a.t. on the scene, let them see what they have to deal with.

the on-scene commander made a decision between himself or herself, the s.w.a.t. team, the negotiators, now is the critical time to do it. the best way, willie, is for a negotiator to be talking to the subject when you go through. as you've heard from the police, they used a bearcat, an armored vehicle, to burst through the wall. part of the reason you go through the wall is because there is probably concern that the subject may have put a booby tr trap, on explosive device on the door and they didn't want to get law enforcement officers killed going through to get the hostages. so they go through the wall and use tactical diversion devices, called flash bangs, to make very loud noise, smoke, a flash, to get the subject to look the other way and then law enforcement engages him. we're told at least nine tactical officers entered, engaged the subject in a shootout. at that time he went down.

but of course by that time we're also told that 20 had been killed, 42 had been wounded over this approximately four-hour time period. >> and, clint, i would think this location presents some unique challenges to law enforcement. you have a nightclub that was crowded with police say about 320 people. some of those had escaped during this hostage situation and before it. dark, perhaps. a lot of nooks and crannies in a place like that. what were the specific challenges you'd think as an fbi investigator here? >> well, you've hit on a number of them. number one, there's a high likelihood that the lights had been turned off inside. number two, we're told that there are multiple various size rooms, so it's not like you're going into a big auditorium and it's wide open. when the tactical team breached the wall and went in, they had to not only consider but probably by briefing know how many different little rooms there were, and then they had to individually go in each of those

rooms. and, willie, if you can imagine those conditions. it's dark, now it's perhaps smoky because of the diversionary devices that have gone off. some of the doors are locked because hostages are wounded or simply hiding. the subject may have been in a main room, he may have been in a side room and officers had to go through every door and in every room with the full understanding they were going to engage someone with an assault rifle and a pistol. so it was a terrible situation for the people inside to go through, and obviously a very tough situation for law enforcement. they did what they had to do. but we saw this terrible loss of life and a number of wounded. one more time, we see these shootings across the united states where someone goes in heavily armed. in this situation, willie, with that type of weaponry and likely ammunition, we're told this individual who's likely been identified by the fbi already is not from the local area, so that

suggests some type of preplanning, pretargeting that went on to carry this out. >> yeah, and again the police saying that this guy was prepared and well organized when he entered that nightclub. as the investigation goes forward here, clint, let's talk about how it's been classified so far. the sheriff's office in that press conference saying it's being treated as a domestic terror incident. the fbi saying there's no suggestion of a further threat to orlando or anywhere else. certainly they always have to consider some form of terrorism. what did you hear in the language that law enforcement used in that press conference? >> i think the language was very guarded. we hear domestic terrorism. well, whenever you have this many people killed and wounded, it rings terrorism to all of us. there's no way to get away from that preliminary definition. then the question becomes was it an act of domestic terrorism that was simply centered on that

bar because someone had a problem with it? was it an act of foreign terrorism where individuals have come in and were prepared and because of the -- because it was a gay bar, for example, they made a decision they were going to attack and make some type of statement against america or against that type of establishment. we just don't know. what we do know is that there are a number of individuals in the united states who don't like other people's lifestyle, and this could very well be just some angry person for whatever his or her reason that carried this out. but that's the challenge for law enforcement. if the fbi thinks they know who this guy is, whos sho the shoote believe male, is, they'll quickly run him down through his cell phones, through his e-mails, through his automobile. today is the day that if we find this guy's car and determine there's no explosive devices or anything else in it, there's

chips in the car that can tell us where that car has been. so technologically the fbi and the other law enforcement agencies are going to have a lot of information to work with. the challenge right now is to gather that very quickly and find out if there was anybody else involved either in the shooting or who supported the shooter. >> clint van zandt, stick with us. we'll talk with you much more throughout the morning. 20 people dead approximately according to orlando police, 42 more transported to three area hospitals. a terrible night in orlando. we'll be keeping you updated on all the details when music: "pretty woman" with roy orbison ♪ of course you go all out for date night... ♪ ...even if you're just staying in. ♪ walgreens has all the beauty products you need for whatever makes you feel beautiful. walgreens. at the corner of happy and healthy.

♪ we're back on a sunday morning. it's june 12, 2016, following a breaking story overnight. a mass shooting at a popular gay nightclub in orlando, florida. president obama has been briefed about the shooting, directi that the federal government provide any assistance necessary to pursue the investigation and to support the community there in orlando. we are also waiting an updated news conference from orlando police. in the meantime, here's what we know so far. [ gun fire ] >> that's gun fire at approximately 5:15 a.m. east coast time which was the end, we believe, was shootout between a gunman and police s.w.a.t. team, federal and local officials on

the scene. orlando police say approximately 20 people have been killed by the gunman. another 42 taken to local hospitals. the gunman killed by police after the s.w.a.t. team stormed the nightclub. it all started around 2:00 this morning and that's when police first heard shots fired. a uniformed orlando police officer was working security and said a man walked in with that assault-style rifle and gun with him. a scene of terror began to unfold both inside and outside the club and then after a three-hour hostage situation around 5:00 eastern time that's when the police moved in. by 6:00 a.m. the police tweeted the gunman had been killed. a chilling facebook post when the shooting started on the page for pulse nightclub. it reads simply, everyone get out of pulse and keep running. let's turn now to pete williams. he's been looking at all of this for us. what more can you tell us? >> a couple of things for you, willie. first of all, authorities are

working very hard to try to figure out who this person is and what the motivation is. they believe they have an identity. what we are told by several local and federal officials is that the name that they're investigating is omar mateen, the last name is spelled m-a-t-e-e-n, born 1976 in new york, and had an addresslucie, . they believe he was living in florida and they're looking very closely if he had been radicalized of islamic propagan propaganda, isis propaganda, nothing definitive. they can't say for sure if this is a purely domestic matter whether this person was radicalized entirely by local influences or international influence. that is a very important question, but one they're not prepared to answer because they just don't know the answer. right now there are three

focuses of the investigation. one is at the nightclub itself where the forensic investigation to try to reconstruct what happened will be going on for many days. that will take a long time. that club is going to be closed for a long time while they try to figure out what happened. secondly is to try to interview the victims who are inside and who are being treated at hospitals of people who managed to get out to get a better picture from them of what happened because the eyewitness information will be so important and the third part and the most aggressive part for the federal authorities at this point is figuring out who this person is and reconstruct a time line leading up to the attack, who were the influences and who was this person in touch with. looking at the social media, the emails and the phone calls and anyone he may have been meeting with and trying to put his life together in the many days leading up to this and try to figure out what the influences are. all of those are very active at this point. >> omar mateen is the name pete williams is giving us, born in

1986 in new york, isis propaganda that can make us think of san bernardino-inspired attacks. do we know any more specifics about by whom he may have been radicalized? >> well, i would draw a big distinction with san bernardino for a couple of reasons. one is remember the people that carried out the san bernardino attacks were radicalized well before that event. >> right. >> the woman involved in that was radicalized before she even came to the u.s. what this -- if this person is born in new york, we were told he was a u.s. citizen so that would explain that, but was this a case of two models to look at when we look at international terrorism or this kind of isis extremism. one is people send here to carry out attacks. it doesn't appear to be that. the second thing is people radicalized by isis influences and isis has been desperately doing this for almost two years now, this relentless social

media propaganda to carry out attacks. was it that? was it something different? >> no clear answers to whether this was merely a target where a lot of people gathered or if it was targeted because it was a gay nightclub. all of that to be determined. >> you described this as an isolated incident. quoting some of your law enforcement sources e is that still the conclusion that this was a man operating alone? >> yes. it's an important point for many reasons and one is if you look at some recent attacks overseas, there have been more than one location. this doesn't seem to be the case here. no indication that anyone else was involved at this point or that other attacks were planned or that someone was trying to carry something out elsewhere. no connection to the shooting death of the singer a couple of days ago, they say. so this does appear to be a one off as far as they can tell. >> pete williams, thank you so much, we'll be talking to you again, shortly, i'm sure. let's bring in gabe gutierrez,

he's on the scene in orlando where this took place just a few hours ago. gabe, good morning. >> reporter: good morning. this is still a very active investigation. police are keeping media and bystanders several blocks away from the nightclub. as you mentioned, 20 people are dead and at least 42 wounded and rushed to local hospitals and investigators are treating this as an act of terror, they say. as you mentioned the shots rang out around 2:00 a.m. and witnesses described a chaotic scene. one witness said he had to climb over bodies to escape and more than a dozen others trapped in a bathroom as they ducked for cover. friends and loved ones of those inside who came to the scene and were at the perimeter including one mother who says that she didn't know what had happened to her son and she spoke to us. let's take a listen. >> my son was in the nightclub with his boyfriend and other

friends, and i know that his boyfriend has been shot multiple times and is in the emergency room, but i don't know where my son is. no one can tell me where my son is. >> reporter: obviously, a very emotional scene here, and that confusion played out for several hours around 5:00 a.m. local time and that's when authorities made the decision to use an armored vehicle to plow into the nightclub and use an explosive device in order to distract the gunman. that gunman was killed in a gun fight and as pete was mentioned he was found with an assault-type style rifle, a handgun and another type of unspecified device. the investigation now continues for a motive. willie? >> agonizing for that mother and so many other people waiting outside that nightclub for answers as police say there were approximately 20 dead and many more scenes like the one from that mom playing out in orlando.

let's turn to jim miklaszewski at the white house this morning. what is the president saying about this. >> reporter: in a white house statement issued minutes ago by press secretary josh ernest, the white house was briefed by lisa monaco. she's the assistant to the president for counter terrorism and homeland security about this tragic shooting according to ernest and in it it says our thoughts and prayers are with the families and loved ones of the victims. now the president has asked that he receive regular updates on the investigation into this, and he has ordered all federal agencies that should be involved to provide whatever kind of support in the investigation or the aftermath to assist the community after this tragic shooting and during this tragic time. now according to officials we talked to, so far it appears that there is no immediate change in the president's schedule and no immediate plans for any kind of formal briefings

out of the white house, but as this develops we would expect to receive further staples. >> homeland security joining in the fbi looking into all of this. jim miklaszewski at the white house, thanks very much. we'll have much more on the shooting in orlando. again, approximately 20 people killed in a popular nightclub pulse. the shooting began at 2:00 in the morning when a man walked in and he was engaged by a uniform police officered working security, but for three hours a hostage standoff ensued and 42 people transported to local hospital and some of them put into the back of police pickup trucks because there were so many of them. "sunday today" will be back after these messages. bill's family went to lowe's to find him the

snack patrol! it's snack justice. we're back on a sunday morning with continuing coverage breaking news out of orlando. police again saying approximately 20 people killed and another 42 taken to area hospitals. that number of 20 is the caveat approximately coming from the police because they just don't know yet, they say. the gunman identified by several

law enforcement sources is omar mateen, he is dead, killed by police when a s.w.a.t. team swarmed the nightclub in orlando. jim cavanaugh is an nbc law enforcement expert. good morning. pete williams reporting to us that law enforcement looking into the distinct possible they this man, omar mateen, born in new york, with an address of port st. lucie, florida, had been radicalized by isis propaganda. what do you say when you put these pieces together. >> you have to see if he was inspired by this attack. we've known isis have thrown gay men off of buildings and been awful to gay citizens and that's in their dna and domestic terrorism and they've attacked the lgbt community and you can have an individualized bigoted

motive. this is a u.s. citizen from new york, so they're looking at those threads in there. was that what the guy was reading? was he really inspired to do it? we also have the model of the bataclan theater so if he's an internationally-inspired person did he just go after this nightclub because it's a big nightclub like the isis guys went after the bataclan because it was a big nightclub in paris. so is this a big nightclub in his world in central florida? so that's what they've got to put together, willie, the white collar side and they have to dig out through that, the computer and the cell phone and where he's been, who he's talked to and now his name is out and the agents and police are getting out to associates, friends and family to get this guy. >> take us to through the investigation, since 2:00 in the morning jumping ahead to 5:15 when the decision was made to storm the pulse nightclub and take out this guy, what is law enforcement doing in term of the investigation and finding out

who he is and what he's connected to? >> right. it ramped up from the first orlando officer engaging him and pushing him to a static situation and s.w.a.t. comes in, and onscene command and negotiators talked with him and they squeezed him down and they decide they have to make a tactical entry, explosive entry, bear cat, flash bangs and they engaged him in a gun battle which you played earlier and then it's static and it ramps down and the investigation ramps up. forensics, white collar, behind the scenes and you know, looks for terrorism links. domestic terrorism links or internationally inspired links or a self-proclaimed link. some other reason that it may look like terrorism inspired, willie, at the moment and it comes down to be that he's an individualized person and he dreams this up himself. so we don't really have the

answer. that's what the agents are struggling with. they'll try to come up with it because we all want to know and it makes us safer if we do know because we can always counter killers if we know how they think and where they come from and why they think things and it doesn't help victims, sadly, today, we have 63 casualties in this eventual because a guy got into a club with a rifle and obviously reloaded it a few times, probably some 30-round magazines or larger and just poured bullets into the crowd and fighting with the s.w.a.t. team. >> jim, i'm looking at the overheadshots and thinking how challenging this must have been for law enforcement and the s.w.a.t. team and you have big rooms and small rooms. it's dark in there, clearly, at 2:00 in the morning and this began until 5:00 a.m. and as you look at it, what kind of challenge would that be for the people who wanted to go in and get the guy?

>> it always is a challenge for s.w.a.t. which is worse or a giant mall. >> they had the orlando officer who engaged him and those other two patrol officers, those were critical because once they got it once they got it static, they could tell the s.w.a.t. commander, he is in the back room in the back section. he's holding people back there. so they have it isolated down. they'll quickly get the inner perimeter. that's the magic of s.w.a.t. they'll get the inner perimeter. they'll keep it tight and get him on the phone and they'll start squeezing him down until his world -- he won't be able to move and eventually, you know, they'll win. they'll win the gun battle, which they did today. so the patrol officers -- the officer working the extra duty, real heroes because they were able to get him isolated not only in the building but maybe in a part of the building. that really helps the s.w.a.t. command when they get there. >> you're talking about the

uniformed orlando police officer who was working security about 2:00 in the morning when this suspect who we know now is omar mateen, a united states citizen walked up with an assault style rifle, hand gun and some type of device as police described it and just started shooting. he was engaged by the uniformed police officer who called for backup. thank you. we'll be right back after your local weather and this short break. good morning here on this sunday waking up to sunshine. we are expecting to see the sunshine stick around all day long. as we move through the day we are going to see warm temperatures. not as hot, though. 70 in san francisco today. low to mid-80s as we head through the day for our inland valleys. we do have a chance for midweek cooling and maybe some showers as we head to thursday. we'll talk about that in about 15 minutes. our bright, bold ocean spray craisins® dried cranberries

what. and it was -- >> christopher hanson describing the chaos inside the club. he went on to say he saw a victim lying face-down shot in the back. took a bandana off his head and plugged the gunshot wound to hopefully save the person's life. that's what was happening inside the pulse nightclub just a few the pulse nightclub just a few hours ago as approximately 20 i will change you. change your goals to get you home earlier every day. sometimes i will give you superpowers. but sometimes, i'll make you feel like the weakest man in the world. i will test your patience to make your heart softer... ... and your limits to make you tougher. but i promise dad, it will be the greatest journey of your life. ♪ tthe whitenessmy wasn't there as much, my teeth didn't look as healthy as others.
