of the bridge collapse. tonight, the state of emergency here in baltimore after a cargo ship hit a major bridge and caused a catastrophic collapse. the dramatic video of that massive container ship ramming into a pillar on the francis scott key bridge. in a matter of seconds, the bridge collapsing in a mass of twisted metal. moments before the collision, the ship issuing a mayday. authorities stopping traffic with just seconds to spare. tonight, my conversations with the mayor and governor, and witnesses who captured some of the stunning images. what do you think of when you look at the video now? >> still in shock, definitely. in disbelief. >> and now, that urgent search. a construction crew filling potholes in the bridge now missing. two found alive, but six unaccounted for. the all-out effort by

sea and by air. and the questions, why did the ship lose control? and how could it happen in one of the country's biggest ports? our full coverage ahead. also tonight, the high-stakes battle at the supreme court over the abortion pill. the major case that could restrict access, including through the mail. what the justices signaled today. the new details and what was found in the federal raids on the homes of sean "diddy" combs, and his attorney firing back tonight. >> announcer: this is "nbc nightly news" with lester holt, reporting tonight from baltimore. >> good evening, everyone, from baltimore. it was described as a cathedral of american infrastructure. tonight, the francis scott key bridge is a mangled ruin. daylight revealing the twisted wreckage. pinning the ship below. two people were rescued, but six missing road workers are now feared dead, according to their construction company

just before impact gave officials just enough time to stop . officials say a mayday call from the ship just before impact gave officials just enough time to stop traffic and prevent more cars and people from falling into the water. thousands of people traverse this bridge every day, and though president biden is vowing to rebuild, it could take months after a disaster no one saw coming. >> at this point, we do not believe that we're going to find any of these individuals still alive. we are going to suspend the active search and rescue efforts. >> reporter: what remains of that structure now piles of twisted metal on top of a container ship, after a nightmare unfolded early this morning. >> the whole bridge just fell down. >> reporter: a camera was recording around 1:30 a.m. you can see cars crossing the bridge as a ship called the "dali," with smoke pouring out of it, gets dangerously close to one of the bridge's pillars and then hits it, sending the massive bridge tumbling into the water.

>> be advised the entire bridge, the entire key bridge is in the harbor. >> reporter: officials say an eight-person construction crew was on the bridge fixing potholes. you can see lights blinking from their parked vehicles before the roadway crumbled. rescuers found two survivors. authorities say six people are missing. the construction company told nbc news they are presumed dead. >> yo, what the [ bleep ]! >> reporter: toby gutermuth had just gotten off work and captured this stunning video. >> i saw what i thought was cargo falling off the front of the ship, causing some splashing. so i started recording. >> reporter: what do you think of when you look at the video now? >> still in shock, definitely. in disbelief. >> can't believe that happened, you know. >> reporter: toby and his friend christian miller telling me they narrowly escaped the disaster. you had gone across that bridge? >> oh, yeah, we had gone across the bridge. >> reporter: within? >> within 30 minutes, roughly. >> reporter: of the accident. >> yep. >> and were ready to

leave and go back across the bridge any minute. >> reporter: what did it sound like, when the ship made impact? >> you could hear scraping, metal debris, debris hitting the water. >> reporter: and tonight, we're learning about remarkable efforts that likely saved lives. video shows the last two cars crossing the bridge about 30 seconds before the bridge fell. the ship had sent a mayday signal before the collision, allowing authorities to stop any other vehicles from going across. >> i need one of you guys on the south side, one of you guys on the north side, hold all traffic on the key bridge. there is a ship approaching that just lost their steering. so, until they get that under control, we got to stop all traffic. >> reporter: how is it that traffic was stopped in time, civilian traffic across the bridge? >> that is heroic work of some of our state law enforcement

officers. they undoubtedly saved lives with their actions. >> reporter: authorities say the ship had lost power and propulsion. you can see the lights go off and on multiple times before it hit the bridge. shipping company synergy marine group says the crew did not suffer injuries, and it's cooperating with the investigation. president biden vowing the bridge will be rebuilt. >> it's my intention that the federal government will pay for the entire cost of reconstructing that bridge. >> reporter: while the governor telling me he's met with the families of the missing. >> it was heartbreaking. when you're working on a bridge, you don't think that's a dangerous place to work. >> reporter: what gives you hope? >> the thing that continues to give me hope is a commitment we made, that we are a place where we say, we leave no one behind, and we made that commitment to the families, and we're going to continue searching. >> we're getting a look at the scale of the disaster from the air. tom llamas joins me. you spent time over this today. it's a really huge area. >> it is, lester, good evening. we flew right over the disaster zone. there is a massive circular perimeter filled with all types of ships. but what you sense and what you see immediately when you fly over this disaster is that the port of baltimore is not opening up any time

soon. tonight, the view from the air over this disaster devastating. chunks of bridge and strips of steel sandwiched across the front of the "dali" cargo ship. crushed containers marking the point where the structure buckled. the rest of the francis scott key bridge under water. late this afternoon, we took off over the crash site. as we fly over this disaster, you can actually see how the bridge collapsed. the cargo vessel crashing into those concrete pilings, and they essentially cracked, sending the bridge, all that steel into the cargo vessel and then into the river. the water is 47 degrees, and the bridge was 185 feet, nearly 20 stories above the river. the tides and the currents mean the wreckage could be unstable, yet another challenge for rescue workers. from up here, you also get a sense of how big this ship is. it's about 950 feet

long. to put that into perspective, it's about the size of the empire state building. when you look at the deck, nearly every inch of it is covered by containers stacked ten high. >> when i got the phone call, i thought it was fake. >> reporter: just hours before the collapse, longshoreman shawn jackson was loading cargo onto the ship. did you notice anything strange yesterday with the ship or the crew or anything like that when you were loading it? >> no, i did not. just a regular day. i would never thought in a million years that would happen. >> reporter: how dark is it out here at 1:30 in the morning? >> it's dark. i mean, even in daytime, you really can't see through water, because it's murky, you know? so at nighttime, it's even worse. >> at 0600 hours tomorrow, we are hoping to put divers in the water and begin a more detailed search to do our very best to recover those six missing people. >> reporter: and tonight, we're learning more about that missing construction crew that was on the bridge. contractor jesus campos worked with the missing men. he says they're from mexico, guatemala, el

salvador, and honduras. they came to baltimore for a better life and have families waiting at home. he says, "they were good people, people who came here to work." tonight, he is praying for a miracle. tom llamas, nbc news, baltimore. we turn now to the investigation, which will be led by the ntsb. the agency will be looking at why the ship apparently lost power, as we're already seeing major impacts on shipping. here is tom costello. >> reporter: it was pitch-black as the "dali" left port headed out to sea, traveling at 8 knots, just over 9 miles per hour. it took just four minutes from the first signs of trouble to the moment the ship crashed into the bridge. at 1:24 a.m., the lights suddenly went out on the ship's deck. they came back on a minute later, as dark smoke started billowing from the stack. at 1:26 a.m., the "dali" appeared to turn, but at the same moment, the lights went out again. two minutes later, at

1:28 a.m., the ship collided with the bridge. the super structure quickly crumbling into the river below. >> we searched the best we could this sunken vessel. >> reporter: among the questions for investigators, did the bridge have sufficient barriers to protect its support structures? >> once the bridge is impacted directly in one of its piers, key bridge or another bridge, that's going to be the end. >> reporter: under u.s. law, ships entering and leaving u.s. ports must use a local pilot to help navigate the waterways. >> they have all the knowledge of the waterways. they memorize the charts. they can literally draw the chart from scratch on a piece of paper. >> reporter: early this morning, a local pilot was on the ship. >> there is nothing worse on the bridge of a ship when everything goes quiet. >> reporter: already tonight, ships that can't get in are backed up outside baltimore harbor. now 24 ntsb investigators are on the scene. they will recover the ship's data recorders, examine the ship's safety and maintenance records.

>> any sort of maintenance that was done to a vessel. >> reporter: an online database shows the ship has had 27 inspections since 2015, with two deficiencies found. last year, a problem with propulsion, and 2016, the ship hit the port in antwerp, damaging its hull. because the ship is flagged to singapore, a team from that country is also responding. built in 1977, the francis scott key bridge was constructed to handle heavy traffic. experts say removing the wreckage from the water, then rebuilding the bridge, could take years. >> and tom, we understand the fbi is also involved in the investigation? >> reporter: the fbi says there's no indication of terrorism. the fire department says no indication of pollution in the water at this point, but we're going see a major impact on the supply chain. cars and products from europe and abroad not able to get in, and carnival cruise lines just announced they

will move their operations for now out of baltimore down to norfolk for the foreseeable future. lester? >> all right. tom costello, thanks. meanwhile, in washington, arguments at the supreme court today on the issue of abortion and the effort to limit access to abortion pills, the most common method of abortions in this country. here is laura jarrett. >> reporter: hundreds rallied outside the supreme court today as inside, the justices threw cold water on an effort to roll back access to the most commonly used abortion pill in the country, mifepristone. on the market for more than two decades, the pill now increasingly used. but a group of doctors and advocates against abortion rights successfully sued last year to make the pill harder to obtain, the first time a court ever invalidated an fda-approved drug. >> the fda violated federal law in its duty to keep women safe. women are now left to receive these drugs in the mail or in their dorm room without ever having been checked by a doctor for life-threatening

conditions. that's reckless. >> reporter: today, the justices appeared highly dubious. doctors who never prescribed mifepristone and can't be forced to under federal law have the legal standing to sue. >> i don't think you have it for either one of those doctors. >> reporter: the legal fight over mifepristone now focused on the ways the fda made the drug more widely available, including allowing pills to ship by mail, women to use it later into their pregnancy, and other health care providers to prescribe it, changes that if not upheld would limit access to the pill, particularly in red states where in-person abortion procedures are now largely cut off. the biden administration and drug manufacturer urging the justices that second-guessing the fda here could jeopardize approval of any drug on the market. >> we won't go back! >> reporter: back outside -- >> i came out here today because i want to see the abortion industrial complex be dismantled.

>> reporter: melanie salazar came from san francisco. >> i have hope that one day we can live in a united states that is abortion-free in all 50 states. >> reporter: others, like alyssa greenwood, a mom of two who came to court the day roe was overturned, back today with her now 2-year-old. >> i want her to look back as an adult and say we stood up on the right side of this. for all i know, i get pregnant and i don't want to be, or i get pregnant and i can't carry it to term and it's a danger, and i have to be alive for my kids who are here. >> reporter: the court is expected to issue its decision by june. lester? >> all right, laura jarrett, thank you. president biden and vice president harris making a rare joint appearance in the campaign trail today in battleground north carolina. their message highlighting a debate over whether states should expand access to medicaid. our gabe gutierrez is there. >> reporter: darcy will was recovering from a car accident. she says the $700 a month for health

insurance she was paying was unsustainable. how terrifying is it to not have insurance? >> i -- i didn't know what i was going to do. >> reporter: but in december, she was among the 600,000 people in north carolina newly eligible for medicaid, after the state expanded the program as part of obamacare. now adults ages 19 through 64 who earn a little more than the federal poverty line are also covered. >> there are no words to describe the relief, because i was -- i have multiple sclerosis. >> reporter: in a rare joint appearance on the campaign trail, today, president biden and vice president harris visited this critical swing state, making a push for rural voters over health care. >> that's why the affordable care act is so important. >> reporter: democrats have argued by not expanding medicaid, the state was leaving more than half a billion federal dollars on the table each month. >> access to health care in rural communities is going to be more stable. it also means we're going to have a

healthier workforce. >> reporter: but ten other states are still holding out, among them, florida. >> there is a significant cost. >> reporter: republicans in florida argue expanding medicaid is fiscally irresponsible and takes resources away from more vulnerable populations. >> we don't want a group of able-bodied working aged adults coming in and impacting health care for those kids and also people with disabilities. >> reporter: but as the 2024 campaign ramps up, democrats see health care as a winning issue. also on the trail today, independent presidential candidate robert f. kennedy jr. announced his running mate, silicon valley attorney nicole shanahan. lester? >> gabe gutierrez, thanks. in 60 seconds, the bombshell raids on sean "diddy" combs' properties. we'll have new details of what was found inside, plus how his attorneys are firing back tonight. flare-ups that could permanently damage my lungs. with breztri, things changed for me.
