help law enforcement move closer to a capture, but the fbi says it still needs the public's help. tonight, the fbi releasing new security footage of the capitol hill pipe bomb suspect, preceded by a caption saying "help us identify this individual." from 7:40 p.m. on january 5th on south capitol street, the suspect wearing a gray hoodie and mask is seen walking down a sidewalk. the suspect stops, puts a sack down on the sidewalk and appears to be looking down by something. at one point a dog walker walks right past the suspect. another k4ri7 at 7:52, the suspect stops near the corner of canal street and south capitol street. the suspect leans forward and seems to be tending to something. the suspect gets up, sits down, later gets up again. a third clip at 8:14 p.m., the suspect is filmed walking down the alley between the republican national committee building and the capitol hill club. in a fourth clip also labeled at 8:14 p.m. the suspect is seen walking past the entrance to the capitol hill club on first street and briefly stretches an arm. the fbi has said the two bombs found near democratic and republican party headquarters were placed between 7:30 and 8:30 eastern time on january 5th. >> these pipe bombs were viable devices that could have dn detonated resulting in serious injury or death. >> reporter: previous surveillance video obtained by "the washington post" captured the suspect moments before they placed the bomb near republican party headquarters. >> those bomgs were probably intended to distract the police from the capitol to someplace else. there were probably a significant number of participants in this that knew what they were doing, preplanned it, brought with them the equipment they needed to do what they were attempting to do. >> reporter: the fbi also identified the suspect's shoes as nike air max speed turf shoes in yellow, black and gray. with enhanced photos of the shoes along with pictures of the bombs, a law enforcement official says the bombs were rigged to egg timers and filled with an explosive powder. the fbi is asking the public for help by reporting any tips. >> you may noticed this pure purchase the galvanized pipe. he may have had multiple kitchen timers as well, an interest in explosives, making black powder or research these topics. >> reporter: tonight the fbi along with the bureau of alcohol, tobacco, firearms and explosives is offering a reward of up to $100,000 for information leading to identification of the pipe bombers. they've said in recent weeks this individual could still be a threat. >> he certainly could. brian, thank you very much. let's bring in senior justice correspondent evan perez, chief correspondent jim sciutto and phil mudd. what can we learn from the video despite the fact we can't see the suspect's face? >> think of the tens of hundreds of thousands of people who will see this. think about the person who saw the shoes. the person might have discarded the shoes at this point. what if they saw the shoes a month ago. think of somebody who had a friend that talked about being there, and they look at this video and say this is my friend. i've had people email me to my email account, look at how the person walks. my friend walks like that. so forget about and take aside the question of whether we can see the individual's face. clothes, how they walk, whether they've said something to a friend at a party in the last month, there's a lot of stuff you can learn and there are thousands of people watching, wolf. >> is it remarkable, phil, that the fbi is still asking the public for tips more than two months after these bombs were planted right near capitol hill? are cases like this actually solved with the help of the american public? >> oh, heck yes. i can see from a public perspective you can say with an event of this significance, why haven't you solved this? remember, there are 800-plus people who went on to the capitol on that day. this individual was the day before. maybe he or she didn't tell anybody. remember one thing, wolf. when you look at the top ten list from the fbi, people who are the most prominent subjects, and presumably people who are operationally careful, people who are prominent in terms of the crimes they've committed and who don't want to talk about it, roughly 30-plus percent of those people are identified by the public. that s somebody calls in, and it's not the fbi who solves it. somebody calls in and says i saw that guy on the top ten list, i know that person. the public information that solves these crimes is really significant, wolf. they'll solve this eventually. >> jim, i know you've been working your sources and getting new information. do you think this video finally could lead to the breakthrough that authorities have been waiting for? >> speaking of folks both in intel and law enforcement, they make a couple points. one, it's possible these videos are entirely new. that would be unusual given the fbi's resources, that it's equally plausible that their leads have run cold at this point, right? and that the fbi finds it necessary to reach out to the public for help more aggressively here by sharing all it has and says, listen, help us find this person. the other point that officials have made to me is that the profile of bombers like this is such that, if they attempt to strike once, they may try to strike again, that if they're on the loose, they may feel emboldened and look for the next opportunity. that speaks to the urgency of going to the public now, show all your cards and say we need to find this person now to make sure that they don't attempt to strike again. >> evan, the fbi also released a very close-up picture of the timing device on one of the bombs. what does that tell you about the theory that these bombs could have been used potentially as a distraction during the actual riots that occurred on january 6th? >> wolf, i think i have more questions now about that theory. that is a theory we've heard from the fbi, from prosecutors, that the belief -- also some of the testimony we heard on capitol hill in the last couple weeks, that this was a diversion nair tactic oochs, perhaps set to go off and draw police away from the capitol in time for the insurrection. if you look at the timing device, it shows it's a simple kitchen timer, appears to be about an hour. if these two devices were placed there between 7:30 and 8:30 p.m. the night before, i think you can reasonably see that this would have gone off the night before, not on january 6th. so then that raises new questions, right? again, the fbi and prosecutors have not made any assumptions about who the bomber is. were they connected to the six? this is an operating theory. this is not a sophisticated thing. this person was using home made black powder. it draws, perhaps a different picture of what we were thinking about. if this device had gone off the night before, not on the morning of, and had not been found the morning of, perhaps the security picture at the capitol would have been far different tr what we found on that day. >> that's a good point. phil, the suspect clearly still at large two months after the attack on the u.s. capitol. are you concerned the fbi might never be able to find this guy? >> no. i think there are two concerns. one is public and one is from my own life. the public concern would be, it's been a while, as you suggest, wolf, we'll never find them. as someone who watched the fbi threat briefings from the former fbi director for years, i remember the former director i worked with, mueller, for years asking about one guy, one guy, whitey bulger. he first went on the top ten list in 1999. he was arrested 12 years later. so let me be clear here. the difference between the public concern that this person hasn't been picked up in a couple months and the chance that the fbi -- the fbi in my experience is like a dog with a bone. the chance that the fbi will never find this person, they'll find this person. the one reason -- and let me finish by saying this. evan's points are so significant. this person knows they're being hunted. the reason they need to be hunted faster is they know they'll be picked up eventually. the fbi will find them, wolf. they'll get him. >> i suspect someone who knows this individual knows those shoes, those nakike shoes that this guy was wearing. we'll watch that closely in the fbi seeking information document that you see right there. you see the shoes are high highlighted because they're very, very specific shoes. jim, are officials worried that the suspect potentially could pose a threat as long as this person is on the loose? >> absolutely, fits the profile of the kind of person who would go through the trouble of planting bombs like this, that they would look for another opportunity to do so. might feel emboldened, that they've been able to evade capture for a couple months. it speaks more broadly, wolf, to why you have folks when they look at capitol security in the wake of january 6th, making the kind of recommendations we're seeing, more u.s. capitol police officers, retractible barriers around the capitol, but also, crucially, intelligence. that intelligence gathering being something they want to beef unfortunate specifically for threats to the capitol, but also to threats to members of congress in their home district. intelligence, that's what we're looking at here. they want to be able to do that better in the future in the events of this. >> jim sciutto, evan perez, phil mudd, thanks very much. we'll stay on top of this story. we'll also break down the benefits tucked inside the covid relief bill and the potential long-term costs with the number three house democrat, congressman james clyburn is standing by. we'll discuss. we're going live to london where there are new details emerging, details on the queen breaking her silence about the meghan and harry interview. we kept going. working with our customers to enable the kind of technology that can guide an astronaut back to safety. and help make a hospital come to you, instead of you going to it. so when it comes to your business, you know ♪ ♪ (kids talking) we'll stop at nothing. pnc bank believes that if an app so when it comes to your business, you know can help you track your pizza... come on cody, where are you buddy?

[ tires screech ] well, that came out of nowhere. we're following last-minute maneuvers on capitol hill. the house has just authorized a full floor vote tomorrow. let's go to our chief white house correspondent kaitlan collins. this is truly a significant moment for president biden. >> reporter: it is, wolf. we're told he's eager to fine this bill. he's not there yet. they have to get through one more vote expected to happen tomorrow where he can put pen to paper and get this signed. we're expected him to sell this bill, pitch it to the american voters and talk to them about what's inside of it. that also comes as he's dealing with another challenge on the u.s. southern border, where he sent a delegation of senior officials over the weekend. you're seeing record numbers of children being held in detention facilities. typically they're supposed to be processed out of those pretty quickly. right now this is a major challenge facing the biden administration. they're not ready to call it a crisis yet. with his stimulus plan on the brink of success, president biden is now waiting to make it official. >> hey, buddy, how are you? >> reporter: the president visited a washington, d.c. hardware store today as he prepares for a final vote on his $1.9 trillion coronavirus relief package. >> i'm so excited. i just can't hide it. the rules committee just finished its work. >> reporter: though some progressives have complained the sweeping bill doesn't go far enough, it gained the endorsement of one of the most prominent members. >> this is the most significant legislation for working people that has been passed in decades. this bill is enormously significant. >> reporter: the white house says eligible americans can expect to receive stimulus checks this month, but in a change, biden's name won't appear on them like trump insisted. >> he did not want his name to appear on the checks. >> he didn't think that was a priority or necessary step. his focus was on getting them out as quickly as possible. >> reporter: when biden does sign his name on the relief bill, it will be a defining moment of his presidency. the bill also includes an enhanced child tax credit, increased child care subsidies, extended unemployment benefits and broader eligibility for subsidies under the affordable care act. sources say biden will tout the bill when he addresses the nation in primetime thursday night. meanwhile, his campaign promise of a more humane response to migrant surges on the southern border is now being tested. >> we're not trying to close our borders. we're trying to create an effective, moral, humane system. it's going to take some time to do that. >> reporter: thousands of migrant children are backed up in border patrol facilities amid a surge that exceeded the peak of the crisis in 2019 when facilities were overcrowded and migrants were forced to sleep on floors. >> we're still digging our way out of a dismantled, immoral and ineffective immigration policy that was being implemented by the last administration. >> reporter: the number of migrant children in custody along the border has tripped in the last two weeks, but republicans say the administration hasn't explained how they'll handle it. >> i saw the white house press secretary, jen psaki say she was heartbroken by what's happening at the border. being heartbroken isn't a policy. so we expect to see action, and the american people expect to see action. >> reporter: based on what that senior delegation that traveled to the border over the weekend is telling president biden, we're told that briefing hasn't actually happened yet. they're expected to tell him what it is that they saw. another question that's been raised to the white house, wolf, is whether or not cameras can actually go inside some of these facilities. remember, at the height of the crisis in 2019, that's how we saw so much of what was happening to these migrant children, of course, under the separation policy, the incredibly severe one by the trump administration. so today the white house press secretary did say they would allow cameras in, but we we're still waiting for a time frame of when exactly that's going to happen. >> so heartbreaking to see, these 13, 14, 15-year-old kids separated on the border from their moms and dads. kaitlan, thank you very much. let's discuss this and more with the third ranking democratic in the house of representative, congressman james clyburn. thank you for joining us. the white house says this covid relief bill is one of the most progressive pieces of legislation in american history. do you agree with that? >> thank you very much for having me, wolf. yes, i do. the fact of the matter is, you have to go back to maybe 2009 or maybe 2010 when we passed the affordable care act. that to me was a big deal, i thought, maybe the biggest i'd ever been a part of. this one i think is even bigger than that was. now, it will not have the longstanding circumstances that that had, but we just rescued the lives and livelihoods of a lot of people. when you're dealing with the affordable care act, that was, let's say, one corner of a person's world. in this instance, we're talking about bringing back livelihoods, getting people back to work. and there are some things in this bill that are not getting talked about. "the washington post" this morning has a very interesting headline saying this bill does more for black farmers than anything since maybe civil rights act of 1964. that's a big deal. and there is a lot in this for black farmers. 1898 schools. a lot of people are not familiar with what that means. those are the land grant colleges in the form of slave states, big-time underfunded in recent years. this bill really does a lot for rural hospitals. >> it's got almost $2 trillion in there, congressman. it's going to help tens of millions of americans once those checks start going out, including foyer r their kids. what's your message to republicans. i doubt any republicans will vote for it in the house. what's your message to republicans like minority whip steve scalise who says this bill is simply too big and will leave the next generation of americans with, quote, mountains of debt? >> i would say to mr. scalise, the mountain of debt that we ought to be worried about is that $2 trillion tax cut that he and his republican friends gave to the upper two or 3%, maybe 10% of the american people. the fact of the matter is, that $2 trillion did nothing for the people whose lives we now have to rescue. he is the reason in large measure for what we're going through today. so i would say to him that over 60% of republicans out here, 71% of independents all support this legislation. just because we can't get the partisans on capitol hill to vote for it, doesn't mean we aren't doing it for republicans out in hither lands. that's what joe biden said from the get-go, he was going to be as much of a president for those who voted against him as he is for those who voted for him. >> that's what the recent public opinion polls show, that there's a lot of support out there for this, even though there's not going to be any republicans in the house, there weren't any in the senate, who would vote vote it. i want to get your reaction to the high-quality video that the fbi put out showing the pipe bombing suspect who has been on the loose since january. what does this say to you about the scope of the continuing, on going threat to members of congress and to congress itself, to capitol hill? >> i think the threat is still there. i don't think that we are going to be curtailed in our work by it. there is a threat almost in anything you do anymore, but i have noticed a resolve among my congressional friends up here to get the people's work done. we are going to take necessary precautions. nancy pelosi has done a great job making sure the security issues are dealt with. i think we're going to be in a very good place. when people get in a much better mood here, and i think they will very soon, i think they will be able to work together a little better going forward than we have in the recent past. >> that would be good if that happens. congressman clyburn, as usual, thanks so much for joining us. >> thanks for having me. just ahead, the race to increase the supply of covid-19 vaccines here in the united states, and new increases expected this week. will it help you get your shot? and now that the queen has weighed in on the harry and meghan interview, how will the royal family handle allegations of racism? actually it's for botd existing customers. i feel silly. but i do want the fastest 5g network. oh i want the fastest 5g network. are we actually doing this again? it's not complicated. only at&t gives everyone the same great deal. like the samsung galaxy s21 5g for free when you trade in. four, five, turn, kick. we got chased by these wild coyotes! they were following her becau
