elementary school and what happened next. the video was obtained by our austin affiliate kvue and a newspaper. they say they're sharing it to provide transparency to families in mourning and a community demanding answers. >> reporter: tonight, chilling video from the rampage at robb elementary. surveillance footage obtained by kvue and the austin american statesman capturing the moment the gunman crashed his truck at the school, opening fire on witnesses who rushed to help. moments later a teacher frantically calling 9-1-1. outside the school, you can hear the shooter firing at the building. [ sound of gunfire ] >> get in your room! >> at 11:33, a witness capturing the gunman entering the school with a rifle inside he calmly makes his way down the hall.

a little boy rounding the corner as the gunman opens fire as more than a hundred rounds are fired. three minutes later, police arriving. two officers doubling back as they come under fire. 19 minutes after the gunman first opened fire inside, more heavily armed officers arrived, some with shields 36 minutes in, officers are still seen standing in the hallway, guns drawn but still have not confronted the suspect. 48 minutes go by. he fires another four rounds, but still no rescue attempts. at 57 minutes later, more waiting. it's not until 12:50, 77 minutes after the shooter entered the school, 74 minutes after the first police arrive, that a team would finally breach the classroom and kill the gunman. this footage is so distressing the families of those murdered in the school that many of them

say they can't bring themselves to watch. and the mayor of uvalde telling abc news he plans to demand a full investigation into how the video was leaked. >> our thanks to maria. now to capitol hill where the january 6th committee hearing today featured explosive new testimony. here's abc's congressional correspondent rachel scott. >> was time for him to acknowledge that president biden had prevailed in the election. >> reporter: today, the american people heard explosive testimony from some of donald trump's closest advisers, saying they told the former president that he lost the election. >> december 14th was the day that the state certified their votes and sent them to congress. and, in my view, that was the end of the matter. >> was that an important day for you? did that affect sort of your planning or your realization as to whether or not there was going to be an end of this administration?

>> i think so. i think it was my sentiment. >> reporter: the witnesses testified mr. trump was told time and time again there was no path for him to stay in power. but he wouldn't listen. >> i told him i believed at that point that the means for him to pursue litigation was probably closed. >> and do you recall what his response, if any, was? >> he disagreed. >> reporter: the seventh hearing of the house select committee presented in painstaking detail, a president refusing to come to grips with reality, leaving the white house in chaos. >> president trump is a 76-year-old man. he is not an impressionable child. just like everyone else in our country, he is responsible for his own actions and his own choices. >> reporter: instead, trump turned to outsiders who told him exactly what he wanted to hear, like lawyer sidney powell, who

embraced conspiracy theories and suggested seizing voting machines, all without providing any proof of election fraud. >> i would have fired them that night and had them escorted the building. >> at some point you have to put up or shut up. >> reporter: today's star witness, trump white house counsel pat cipollone. >> on a broader scale, it was a bad idea for the country. >> to have the federal government seize voting machines? that's a terrible idea. that's not how we do things in the united states. >> i think donald trump can try and make excuses for bad advice that he was given by people who were not necessarily on the government payroll. it was his decision ultimately. he was the most powerful man in the world, he was president of the united states. the buck stops with him. >> reporter: cipollone was at the white house on december 18th, the day trump's outside advisers and his white house

team almost came to the explosive meeting. >> i opened the door and i walked in, i saw general flynn, i saw sidney powell sitting there. i was not happy to see the people in the oval office. >> cipollone and whoever the other gal was showed nothing but contempt and disdain of the president. >> and they were asking one simple question as a general matter. where is the evidence? >> and she says, well, the judges are corrupt. and i was, like, every one? every single case that you've done in the country you guys lost? every one of them is corrupt, even the ones we appointed? >> reporter: when the meeting broke up well after midnight, trump fired off this tweet, calling his supporters to washington on january 6th, telling them, be there, will be wild. for some in the right-wing fringe, that one tweet was an instant call to action.

the committee arguing that trump summoned an armed mob to washington, d.c., aided by his supporters in the far-right media. >> he is now calling on we the people to take action and to show our numbers. >> if necessary, storming right into the capitol. >> january 6th, there are going to be a million plus armed americans! >> today was supposed to be the day that they presented the evidence linking donald trump to the extremist groups. and it doesn't seem that the direct connection was there. there were a number of indirect connections. >> i lost my job, sold my house. it changed my life. not for the good. >> reporter: this former trump supporter of ohio also testifying that he answered the president's call and stormed the dol capitol. >> when you heard from president trump that the election was stolen, how did that make you feel? >> i was very upset.

that's basically what got me to come down here. >> reporter: he described himself today as a family man, a working man. he says he came to washington on the 6th because trump told h heus ple guilty to disorderly conduct. >> so why did you decide to march to the capitol? >> um, well, basically the president got everybody riled up, told everybody to head on down. so we basically, we just followed what he said. >> reporter: in the front row, watching him testify, another man whose life was changed on that day. this police sergeant. >> sergeant gonnell's team of doctors told him that permanent injuries he has suffered to his left shoulder and right foot now make it impossible for him to continue as a police officer. >> reporter: as lawmakers spoke of his patriotism and sacrifice, sergeant gonnell quietly wiping

away tears. unfortunately i had to learn how to live with my new limitations and disabilities. but instead of being promoted as a lieutenant because i passed a test, now i had to leave the department. >> reporter: how many years have you been with capitol police? >> 16 years. >> reporter: for him, the hearings are a painful reminder of all he lost. >> without january 6th, i would be working and doing my normal things like i've been doing for the past 16 years. there's no doubt in my mind that had the president done something to prevent january 6th, i would have continued my career like i planned. >> reporter: after he testified, he apologized to gonell. what was that moment like? do you accept his apology? >> i did accept the apology. i'm not a person who is vindicative or begrudge somebody for what they did. i know i'm at peace with myself

with the decision and the actions that i did. >> reporter: today's hearing wrapped up with this warning from the committee's co-chair. > after our last hearing, president trump tried to call a witness in our investigation. a witness you have not yet seen in these hearings. that person declined to answer or respond to president trump's call. and instead alerted their lawyer to the call. their lawyer alerted us. and this committee has supplied that information to the department of justice. let me say one more time, we will take any effort to influence witness testimony very seriously. >> our thanks to rachel. up next, meet one of the world's strongest men helping to reshape the conversation about muscles and might. detect this: living with hiv, i learned i can stay undetectable

his incredible feats of strength make him one of the world's strongest men. but his definition of strength may not be what you think. here's abc's gio benitez. ♪ ask yourself this question. what does it mean to be strong? ♪ does it mean being able to pull a monster truck or lifting a car off of the ground? or throwing around gigantic rocks? those are big rocks.

what's the most weight you've ever picked up? >> so, i've deadlifted 971 pounds. >> reporter: 971 pounds, that's roughly the same as picking up five grown adults or four full-sized refrigerators or an entire grand piano. for rob kearney, being strong is oten measured in herculean feats like these. it makes sense. he's one of the strongest people in the world. ♪ now, before i go on, a primer for anyone like me who has no idea what's going on here, this is the world's strongest man competition. it takes place every year. for more than four decades, these giants come from all over the world to settle an age-old question, who is the biggest and strongest of them all? and rob is one of the fiercest competitors. when you were growing up

watching sports, weightlifting, what was strength to you? >> i wasn't a terribly athletic kid growing up. honestly it was in the weight room where i really found myself. ♪ >> reporter: before long, rob had turned pro, duking it out with the world's mightiest. but beyond the muscles and the mohawk, there existed a part of his life that none of his competitors knew. >> i always knew i was different, but i never accepted as to why. it was always just pushed into the back of my mind, and i never wanted to deal with it. it wasn't until college where i actually dated a girl for about a year and a half. and that was really my only relationship throughout my entire life up until that point. but one day i woke up and i kind of had this epiphany and i was, like, i can't do this anymore. here i am thinking i'm living this heteronormative life and

going to have that white picket fence life with a wife and kids. and finally realized that's not what i want. >> and you're doing it in this hypermasculine sport where you don't know if you reveal who you are what's going to happen. >> yeah. once i realized it for myself and i could constantly look in the mirror and say i'm a gay man and be proud of that, i kind of had this mentality that i realized if people didn't like it about me, i didn't need them to accept it, i was finally accepting myself. and that was opening up these doors that i never knew existed. ♪ >> reporter: opening new doors, more like kicking them in. rob soon took the strongman world by storm, even dubbing himself the world's strongest gay, the first openly gay professional strongman in the sport's history. but even rob's mighty strength was no match for cupid's arrow. >> not long after i had ended

that relationship with the girl, i actually met joey. i looked back and it was honestly like a middle school romance to start. >> reporter: so what was going through your mind? did you realize that he was a pro strongman at the time? >> he was like, i don't really know what this is, i didn't even watch it on tv. i was, like-oh, yeah, that sounds like, like you lift weights. he was showing me videos. and i was, like, oh, you lift like giant boulders and deadlift cars? one that's pretty cool and i want to do that. >> reporter: together rob and joey have become arguably the world's strongest couple. they've written a book, and to their surprise, were fully embraced by their strongman community. and today they're giving me a lesson, how to become a strong man 101. >> so this is honestly kind of like a strongman playground. >> reporter: playground is a kind way to put it. still, i wanted to try my hands at the strongest man's

mo event. those famed atlas stones. >> we have ones that are plenty light enough where first time you could throw them around no problem. >> all right, perfect. is this my stone? >> yeah. >> all right. >> and i'll bring mine up as well. [ laughter ] just a little bit different. >> reporter: from here, you hold onto it and then you're just going to look up at the platform, squeeze it into your body, stand up and get it up on the platform. okay. so you make it look easy. >> get your fingers underneath it. squeeze it, bring it up into your lap. going to sit down, reach around the stone. good. and then lift it up onto the platform. all right. [ laughter ] it wasn't as graceful as yours. >> you're ready to do strongman. >> reporter: okay, sure, i may not be leaving behind my news career to lift rocks for a

living just yet, but for rob and joey, all of this is part of a greater goal. each lift and press, an important step in changing the narrative around what it means to be a gay man. >> i think all too often gay men are seen as weak, and they're typically portrayed as, you know, feminine, flamboyant, and that's really it. gay doesn't have to look a certain way. here i am as a gay man with a mohawk with muscles and competing at the highest level of a strongman. it's been a great way to show people that sexuality really has no bearing on things you can achieve. >> reporter: so what does it mean to be strong? maybe being strong isn't measured in pounds of iron and steel but rather in being true to yourself and ipi
