we talk with their family and friends. >> i always remember jill's smile. i try never to think about the way she died. >> who are keeping their memories alive. >> tributes to the fallen. the man who salutes his firefighter smile and he finishes a 500-mile plus journey live on "gma" and the firefighters who cycled cross-country to honor first responders who died and to help the survivors who struggle to this day. 9/11, we will never forget, america remembers. this is a special edition of "good morning america." and good morning, america. this morning we remember the victims and honor the heroes of september 11th, 20 years after the attacks that shocked this country and the world. >> i think everybody remembers

eactly where they were when they heard the news about the attacks. i remember rushing to pennsylvania to report on united airlines flight 93, which crashed in a field in shanksville. i was on the air with peter jennings that night. 40 passengers and crew on board that plane and this morning we remember their sacrifice. >> and tributes are being held across the country this morning to honor the lives lost, those on the hijacked planes, those in the buildings and, of course, the first responders who rushed in to help and save lives. we have team coverage from the pentagon to shanksville and right here in lower manhattan. >> newspapers around the country marking this day, many headlines with the words, never forget, we begin with linsey davis near ground zero where security is tight ahead of this year's name reading ceremony. good morning to you, linsey. >> reporter: good morning, to you, eva. snipers just walked by us on several of the surroundings rooftops you can see lots of security, nypd certainly on high alert told there are no credible

threats to today's ceremonies which are exclusively for 9/11 families and will include six moments of silence, twice for when each of the towers were struck twice for when each of the towers collapsed then again for the attack of the pentagon and then that crash in shanksville, pennsylvania. on this day 20 years ago, our nation watched the deadliest terror attack on u.s. soil unfold. >> we just got a report in that there's been some sort of explosion at the world trade center in new york city. >> reporter: today law enforcement across the country on alert. security ramping up in new york city. >> there are no specific and credible threats directed against new york city at this time and the nypd is watching, not daily, not hourly, minute by minute. >> reporter: new york governor kathy hochul calling this weekend vulnerable. >> you will see increased presence. the idea is to let anyone know that you mess with new york,

there will be consequences. >> reporter: it's been two decades since one of the darkest days, hijackers taking over four airplanes two crashing into the twin towers of the world trade center causing them to collapse. another plane crashing into the western side of the pentagon and then flight 93 crashing into a field in shanksville, pennsylvania, after heroic americans fought the hijackers. today at ground zero in lower manhattan, a memorial where those towers once stood. strangers, friends and family members stopping by the reflecting pools to pay their respects. sandy hayes' son-in-law scott o'brien watt a computer trade show on the 106th floor of the north tower. >> he was such a good man. he was a good husband, he was a good husband. he was a great son-in-law. >> reporter: this is sandy's first visit to the memorial. >> you look at all of these people that are here and everybody has a story. >> reporter: 20 years later and

the pain still hasn't eased for matthew asaro. he and three of his siblings became firefighters just like their dad karl who lost his life that day. your recollections from that day? >> the bus home and i was like, my dad is a fireman. he's down there, i was proud but i didn't know how it happened. >> reporter: this time lapse video shows the years of reconstruction it took to rebuild a symbol of freedom, st. nicholas greek orthodox church one turned to rubble in the attack, the only house of worship to be destroyed. >> may their memory be eternal. >> reporter: overnight this light shining from within for the first time, the church now rebuilt in the shadow of one world trade center to serve as a national shrine. this morning, a ceremony at ground zero honoring the nearly

3,000 lives lost. families of the victims will read their names aloud and the tribute in light will shine over manhattan tonight reminding the nation to never forget. on september 11, 2001, many will remember the crisp blue beautiful skies of that day that belied the darkness that was coming later on in the day and the weather today much like that. with the beautiful crisp blue skies once again. sunshine on an otherwise gloomy occasion perhaps a fitting tribute to the light and resilience of this city and its people. dan. >> yeah, i believe the technical term that pilots used for this kind of weather is severe clear and that was -- those were the conditions on september 11th 20 years ago and fittingly once again. thank you for your reporting. we know you'll report all day long.

this morning we also, of course, remember the 184 lives lost at the pentagon. abc's chief global affairs right there with a look back at what happened at the pentagon and the security concerns we are still facing on this day. martha, good morning to you. >> reporter: good morning, dan. they unfurled a flag here just a short time ago on the side of the building that was struck by flight 77, 184 people died, 64 of them were on that airplane. that flag this morning, a reminder of 20 years ago when they unfurled the flag over the side of the building when it had a huge gash in the side of the building. also have to say, dan, one of the things i think about morning is that the people who went back to work immediately, back to work in this building, in fact, some of them never left. they were in operation centers here, they had to keep working and not only were they working to try to keep us safe, but they

were, of course, planning a war that this is is the very first time that we have not had troops in afghanistan since we started commemorating september 11th, the defense secretary will be speaking here, the chairman of the joint chiefs of staff will be speaking here. both of those men consumed in the last 20 years by the war in afghanistan and then the subsequent war in iraq. >> well, given that the war in afghanistan is now over, at least for now, as we sit here two decades after september 11th, how has our country changed in terms of the security and safety concerns that we've been facing for 20 years? >> reporter: well, the risk is still here, of course, dan, both the chairman of the joint chiefs of staff and defense secretary said that it would be about two years probably before al qaeda

could regenerate if they regenerated in afghanistan but that was before the taliban took over afghanistan, which is still a shock to so many people around the globe and especially here at the pentagon but they watched those risks constantly and we have the department of homeland security after 9/11, 240,000 employees and much of the fbi's focus shifted to counterterrorism, dan. >> martha raddatz, thank you so much for your reporting. again, i know you'll contribute to our coverage throughout the day here on abc news. eva, over to you. >> abc's juju chang is in shanksville, pennsylvania, where united flight 93 went down an act of supreme heroism by passengers saving so many lives while sacrificing their own. their families still mourning their loss. good morning to you, juju. >> reporter: good morning to you, eva. you know, it's just over this grassy hill that's made even

more beautiful lies the crash site of 93. it is the final resting place for the brave passengers and crew on board, all 40 of them. their families and the town of shanksville has been united in the past 20 years to keep their memories alive. now, one of the major monuments here is called the tower of voices. it's a 93-foot tower representing, of course, flight 93. inside, 40 wind chimes representing the voices of the 40 passengers inside. you'll recall it was the voices of the passengers themselves making dozens of phone calls midflight that gave us an understanding of the heroism that was unfolding on board. they quickly learned what happened to the other planes at the world trade center and at the pentagon. they hatched a plan and they voted to fight back against the terrorists and to thwart their evil plan. they weren't just fighting for their lives but their country at that point. last night here in shanksville, there was a beautiful candle ceremony. each family placing a lantern with a candle inside in front of the memorial, 40 white marble

slabs, each inscribed in the names of one of their loved ones. we spoke to one family of ceecee lyles, a flight attendant. former police officer turned flight attendant actually and her mom shirley says that these families have been united in making sure these memories stay alive. >> when we started here, i mean, it's -- 20 years is a long process and we have met all of these people and then over and over again we stayed over across the street in a hotel for many, many years, many of us, we've gone through births and deaths and we just know each other very, very closely. so, you know, it's just when we go out there, we just, you know, some of them are really heartbroken and we just go out there and we just -- we come here to love each other because our families went down together

and here we are together, so we just fell in love with each other and it's been like that the whole time. >> reporter: and ceecee's family says as a former police officer she was in the thick of it, they believe, on flight 93 and fighting back. today's events, of course include speeches and performances and hear from vice president kamala harris, president biden and the most solemn ceremony when her family and others walk out on to this field and family members are the only ones allowed to. >> all right, juju, thank you so much. we appreciate it. we do move on to president biden releasing a message to the nation overnight as he prepares to visit each of the memorial sites. focusing on the unity that followed the attacks. >> to me, that's the central

lesson of september 11th is that at our most vulnerable in the push and pull of all that makes us human and the battle for the soul of america, unity is our greatest strength. >> white house correspondent cecilia vega is in lower manhattan with how the president will be honoring all of those who lost their lives, cecilia, good morning. >> reporter: hi, whit. good morning to you. yeah, the president is already here. he arrived in new york last night so waking up here in the city this morning and he, as you said, will attend ceremonies at all three sites starting with this 9/11 memorial behind me. from here juju mentioned he will head to shanksville, that hallowed ground in pennsylvania and he after that will head to the pentagon. he's not going to be speaking at all today. he will be laying wreaths but did hear him that the white house delivered overnight and so importantly really focusing on the victims, of course, their families, but that message of unity that is just so

exceptionally important in these divided times we live in. i want to tell you about the president back then on september 11th, 2001. he was a senator to delaware on an amtrak train hided to washington when his phone rang. it was jill biden who walked him through what she was seeing on tv. horrific images. when he got to washington he says he could see that smoke rising from the pentagon site and how upset he was that the fact that senators and colleagues on capitol hill weren't doing business. they had been ee advantage waited. he wanted to see business as normal to send that business back to the american people to stay calm. he did an interview at that time. he actually spoke to peter jennings on abc to express that sense of normalcy. when he was done president bush picked up the phone and called him. the president was headed to a secure location in the midwest and biden told him, come back, business as usual, of course, whit, all of this during this chaotic two weeks after that

withdrawal from afghanistan. >> absolutely and, cecilia, we often see so many politicians and dignitaries attend these anniversaries. who do we expect to be among them? >> reporter: well, the big question right now is former president trump. he's reportedly coming to new york. it's unclear whether he will visit this memorial site here behind me. you heard juju mention former president obama. he'll be here, first lady michelle obama and then in shanksville, you, of course, have george w. bush and kamala harris. they'll be speaking here. all of these presidencies, dan, impacted by what happened here 20 years ago. >> deeply impacted. cecilia vega, thank you so much. we referenced this a few times but 20 years after 9/11 the taliban has, of course, returned to power in afghanistan and abc's julia macfarlane is in london with the latest on what's happening on the ground there. julia, good morning. >> reporter: dan, good morning. 20 years since the 9/11 attack and just under 20 years since the taliban refused to hand over osama bin laden and his fellow

al qaeda leaders to the u.s. sparking then president bush to launch an invasion into afghanistan. fast forward to today and we have that same group, the taliban now running the country and now western intelligence officials are warning al qaeda could use this opportunity and the vacuum left behind by the withdrawal to regroup. meanwhile, there is still thought to be about 100 americans in the country. this week two chartered jets from qatar airways carried out the first evacuations of u.s. citizens since the completion of withdrawal last month. they carried more than two dozen u.s. citizens and several green card holders out from kabul airport. the state department confirmed a group of u.s. citizens and permanent residents were also evacuated over land. however, the u.s. has now halted all incoming flights of afghan evacuees from the two main bases in qatar and germany due to an outbreak of the measles and one last thing, both "the washington post" and "the new york times"

investigating that u.s. air strike in kabul last month. they are now reporting that they conclude that the united states mistakenly targeted an aid worker, not an isis militant. that strike killing ten people including seven children. eva. >> julia macfarlane for us there in london. now to janai norman with the morning's other headlines. good morning to you, janai. >> you guys, good morning. we begin with the latest on covid-19, 1 in 500 americans has died due to the virus. now millions of american workers face a new reality with president biden's sweeping move requiring companies with 100 workers or more to get vaccinated or get weekly testing showing they're negative. governors in at least 19 states already blasting the new rule for businesses and this morning, there is fresh evidence that the vaccine remains highly effective in preventing severe symptoms even against the delta variant. the cdc now reporting that more than 90% of patients in hospitals are unvaccinated. and britain's prince andrew has

reportedly been served a lawsuit. jeffrey epstein accuser virginia giuffre accusing him of sexual assault when she was 17. her lawyers say he repeatedly 0 o avoided a process server. no word if he actually received the papers. prince andrew has repeatedly denied wrongdoing, whit. >> thanks so much. we move to the weather. rob marciano is in brooklyn with what we're watching across the country, rob, good morning. >> hey, good morning, whit. yesterday, not only a beautiful day here in new york city, very reminiscent of 20 years ago on september 11th but the peak of hurricane season and we did have a hurricane make landfall in mexico, a category 2 storm creating flooding and damaging winds and we've got a lot of activity in the atlantic, we've got 80% there in the gulf of mexico of likely not developing for the u.s. but it will bring heavy rain, watching this closely, looks like the southeast coast of texas will be

under the gun for her rainfall and this is larry making landfall with some surf line pictures there in canada. time now for a look at your local forecast. here you go. beautiful morning in brooklyn as we look over to manhattan and one world trade. the firefighters honors their fallen compatriots lost on 9/11. these were members of the fire velo along with their support

team. these cyclists pedalled from santa monica to new york in 40 days and talking with three members of them on their journey. kevin, jamie and jim. thank you guys so much for being with us. kevin, one of the things we say about first responders, when most people's instincts are to run away from a catastrophe, your instincts are to run toward it. you guys have met 9/11 first responders. tell us about them. >> yeah, that's right. all of us were were were were we affected by the deaths of 20 years ago riding for four charity, all of us know dozens of first responders personally and professionally that worked on that pile 20 years ago and that's why we're riding for them. not just for the first responders, but for the military and those that were affected. and the four charities that

we're riding for are going to give back both to providing care for the illnesses and mental health for those folks. and the way the folks can do that is even though our ride is finished, they will be able to donate for weeks coming up. so please, please, folks that are watching this, go to www.firev www.firevelo.com and help us support the efforts we have done for the 40 days to provide funds for those affected by the horrific attacks of 20 years ago. >> firevelo.com. sounds incredibly important given the stakes here, jamie, we have just a little time left. curious in our remaining seconds. you were only 6 when the towers collapsed and when the country was under attack. what motivated you to make this enormous commitment? >> yes, i was 6 years old when the 9/11 attacks happened and although i don't remember that day very well, i'm a part of the

generation that could be ones to forget, but i'm here to make sure that that doesn't happen and that's a cause that's near and dear to my heart. >> it should be a cause that is near and dear to everybody's hearts. we really appreciate the work and effort that you've put in on this enormous ride across the country. thank you very much to all of you and we will be right back with much more of our coverage of this 20th anniversary. keep it right here. ♪ "good morning america" sponsored by the u.p.s. store.

[stomping stops] welcome back to "gma" on this cath morning as we mark 20 years after the 9/11 terrorist attacks. you're looking live at the 9/11 memorials in shanksville, pennsylvania, at the pentagon and at ground zero here in new york city. there will be events at those sites and others across the country today and the names of those who died will be read in shanksville and at ground zero. on the eve of the 20-year remembrance, michael moore hosted a free screening of his award winning film "fair night, 9/11." >> george orwell once wrote it's not a matter of whether the war is not real or if it is, victory is not possible. the war is not meant to be won.

it is meant to be continuous. >> and joining us now is the oscar winning filmmaker, michael moore. i apologize. "fahrenheit 9/11" is what i meant. what do you think about how the government has gone about getting answers as to what happened and has the government been transparent enough in your view? >> no, i don't think so and i think the families of the victims have been very right to demand that the documents from 9/11 be declassified and last week president biden said that he would start the process of declassifying them. there's a lot we don't know. 15 of the 19 hijackers are from saudi arabia. if 15 of the 19 hijackers had been from north korea i think it would have been okay for us to say north korea has attacked the united states or if they've been from cuba but the fact that 15

of the 19 were from this one country and had trained, there's a lot we don't know and i think when these documents are declassified we're going to be able to get our hands on some truth. >> do you think there was some potential desire to back off on saudi arabia because of oil or connections between individual members of the representative governments? >> well, as i pointed out in my film, yes, a bush family and the saudi royal family had very, very close ties. if you remember, dan, in the day or two after 9/11 when all the planes were grounded, the only planes that were allowed to fly were the ones that picked up members of the bin laden family in the united states and members of the saudi royal family. they were allowed to fly and they allowed to fly and leave the country and as the fbi

person said in "fahrenheit 9/11," you know, any time that there is a murder and in this case a mass murder, we always want to talk to the family, we always want to see what they know. that they wouldn't even let them stay so that the fbi could do their job to ask the questions and if you remember, it was another month before the saudis allowed our fbi and our investigators into saudi arabia to interview the families of the hijackers, to interview -- to try and get to the bottom of this. there was not the cooperation from saudi arabia that we should have had. two nights after 9/11, the saudi ambassador to the united states is having a private dinner with president bush in the white house. these are all things in the 9/11 commission report but there were so many documents that weren't allowed to be seen and i think that we should see what's there and the families want closure to this. it's why they're suing the saudi

government. this has been a long, longtime suit going on here, and their own government should be helping them find out the truth of what happened. >> we have just about a minute left. i want to ask you about afghanistan. you were really one of the loudest voices arguing against the launching of that war, now the war is over, what lessons if any do you think the country has learned? >> i worry that we haven't learned all the right lessons, just the way that people were demanding that president biden stay in afghanistan a few weeks ago, don't leave. we can't leave yet. we need a footprint on the ground. a footprint on the ground? that's not our ground. that's not our country. was it right to go after the mass murderer? absolutely. but once he left, once bin laden was gone and that was very quickly we moved too slow, we didn't get in there. he left right away. we stayed. we stayed for 20 years.

i don't ever want to see us invading another country that doesn't have anything to do with the actual defense of this country, of saving lives and that's not what we did for these 0 years. my heart goes out to the families. i want them to know their sons and daughters did not die in vain. those of us for truth and for peace will always remember them, always remember and have them be our example, our guiding light that we never find ourselves again in a situation like we did in afghanistan and iraq. we're better than that, and we have our own issues, $300 million a day we spent in afghanistan. what could we have done in the united states with that money? this is -- this -- i think we have learned that piece of the lesson and now we need to build our country back so that we -- the real terrorism is the poverty and the hunger in this country, the schools, all the things that we need, our people need, universal health care, all of that stuff, why -- we have to

take care of our own people. >> michael moore, really appreciate your time on this somber day. >> and constitutiondolences to lost someone. >> a check of the weather and turn to rob marciano. hey, rob. >> hey, good morning, again, as mentioned yesterday was eerily similar on 9/11, 20 years ago, cobalt blue sky, low levels of humidity, similar weather in three spots high. lighting of course in downtown new york, 78 degrees, shanksville around 70. a few clouds in d.c., 8 degrees. all right. let's look at the fires that are burning, caldor fire over 50% containment there. we had a fresh fire that burned in utah last night with some lightning strikes, so that's going to be a problem too. a lot of lightning across northern california although helpful rain and dry lightning persisting today and tomorrow and extreme heat building again across the southwest. 99 degrees yesterday in denver. you'll be 96 today.

compensation fund is still available to them. >> unfortunately, we continue to get calls every day that somebody was diagnosed with cancer, that somebody has passed away from a 9/11 illness. >> reporter: phil's brother lou was an nypd detective who responded that day. >> it wasn't until 15 years later that lou was told that he had a 9/11-related cancer. he had cancer of the liver and it was stage 4 because it had metastasized. >> reporter: he died in 2019 but not before testifying for the need for the fund to widen its ability to help. alongside comedian jon stewart this was lou shortly before he died. >> i should not be here with you, but you made me come. i will not stand by and watch as my friends with cancer from 9/11

like me are valued less than anyone else. >> reporter: the 9/11 victims compensation fund was set up just 11 days after the attack. its original goal was to help victims and their families. in january of 2011, a new act was signed, it re-opened the fund extending eligibility criteria and extending the deadline to file a claim until october 2016. now rescue and recovery workers could begin to get medical help. but in 2018 word of potential funding insufficiencies, that's when lu and stewart went to congress. >> your indifference cost these men and women their most valuable commodity, time. it's the one thing they're running out of. >> reporter: finally in july of 2019 the deadline to file a claim was extended until the year 2090. >> we realize there was a need for this sort of help and this sort of aid, if you will.

>> reporter: bridget's father was a firefighter who died in 2017 from cancer his family believes was caused by 9/11. today his three children work tirelessly to make sure those like their dad are covered by the fund. >> i never realized that, you know, the years following that people would still be passing away and more people than were lost now than that day. >> reporter: as it stands today, the victim compensation fund has received claims from every state in the nation, puerto rico, u.s. virgin islands and 31 foreign countries with no doubt more to come as this nation continues to keep its promise to never forget. eva. >> phil lipof for us in brooklyn. coming up on "good morning america," the man who has walked from the pentagon to shanksville to new york, his tunnel to towers tribute to his firefighter brother, a 9/11 hero.
