united states oksana markarova will join us for an update. finally, a growing outcry over a crisis at home. how is it possible that the capital city of a u.s. state in the richest country in the world doesn't have clean running water? we'll get an update from the mayor of jackson, mississippi, chokwe lumumba on his city's struggles. it's all ahead on "face the nation." ♪ good morning. welcome to "face the nation." 21 years ago today americans united in their grief and in their opposition to extremist forces who attacked the country on september 11th. it is a somber sunday morning here in the u.s. and in the united kingdom. we are witnessing a solemn

tribute there with crowds lining the streets to pay their respects to queen elizabeth ii as her coffin makes its way from balmoral castle, where she passed away on thursday, to her official home in edinburgh, scotland. we'll have a report from london to an extraordinary period of change in the united kingdom in just a moment. we want to begin here in the u.s. from ground zero in new york to shanksville, pennsylvania, and here at the pentagon in arlington, virginia, americans remembered the nearly 3,000 lives lost on this day 21 years ago. as has become tradition, moments of silence marked each of the devastations of that morning in 2001. two planes crashed into the world trade center towers, the towers collapsed shortly thereafter. a third plane crashing into the pentagon and a fourth brought down in a field in shanksville, pennsylvania. in a sobering and now familiar ritual, the names of the fallen were read a loud.

president biden laid a wreath at the pentagon and made remarks a short time ago. >> our intelligence, counterintelligence professionals in the building behind me and across the government continue their vigilance against terrorist threats that has evolved and spread to new regions of the world. we'll continue to monitor and disrupt those terrorist activities wherever we find them, wherever they exist, and we'll never hesitate to do what's necessary to defend the american people. >> for aid closer look at the evolving threats to the homeland, we begin with the chairman of the senate intelligence committee, mark warner of virginia. good morning to you, senator. >> good morning, margaret. >> 9/11 introduced to many americans for the very first time this sense of vulnerability at home and it launched the global war on terror. i wonder how vulnerable you think america is now. are we paying enough attention to the middle east and to afghanistan? >> well, margaret, i remember as most americans do where they were on 9/11.

i was in it is middle of a political campaign and suddenly the differences with my opponent seemed very small in comparison. and our country came together. in many ways, we defeated the terrorists because of the resilience of the american public, because of our intelligence community, and we are safer, better prepared. the stunning thing to me is, here we are 20 years later and the attack on the symbol of our democracy is not coming from terrorists but it came from literally insurgents attacking the capitol on january 6th. so, i believe we are stronger. i believe our intelligence community has performed remarkably. i think the threat of terror has diminished, but i still think we have new challenges in terms of nation state challenges, russia and longer term, a technology competition with china. but i do worry about some of the activity in this country where the election deniers, the insurgency that took place on january 6th. that is something i hope we can

see that same kind of unity of spirit. >> as you're pointing out, america came together after 9/11 and we are incredibly divided right now. one thing that is potentially quite explosive is this ongoing investigation by the justice department of the former president and his handling of classified information. you've asked for a briefing from the intelligence community. given how sensitive this is, why should anything be shared with congress given that this is an ongoing investigation? >> because as the chairman of the intelligence committee, and i'm very proud of our committee, we're the last functioning bipartisan committee, i believe, in the whole congress. the vice chairman and i have asked for a briefing of the damages that could have arisen from mishandling of this information. and i believe it's our congressional duty to have that oversight. remember what's at stake here is the fact that if some of these documents involved human intelligence, and that information got out, peoples

will die. if there were penetration of our -- >> we don't know that yet. >> -- signals intelligence, literally years of work could be destroyed. we talk about the enormous advances our intelligence community has made helping our ukrainian friends. that comes about because we share intelligence. if there's intelligence that has been shared with us by allies and that is mishandled, all of that could be in jeopardy. we don't know what's in those documents. >> right. >> but i think it is incumbent, as soon as we get approval -- let me be clear, as soon as we get approval, there is some question because of the special master appointment by the judge in florida, whether they can brief at this point. we need clarification on that from that judge as quickly as possible because it is essential that the intelligence community leadership at least gets a briefing of the damage assessment. >> that damage assessment, it has been paused, as has the classification review, and it will take some time. so, a, i'm assuming in your answer there you're saying, there have been no promises of a briefing to be scheduled, is that right?

>> i believe we will get a briefing as soon as there's clarification whether this can be performed or not. >> but why should this -- >> -- the ruling of the judge in florida. >> why should that happen? i want to get to something you said, this is the last bipartisan committee. you and marco rubio, your partner in this request for a briefing, put forth this letter asking for the damage assessment, but lately your colleague has been making some comments that don't sound quite as bipartisan. he's compared the justice department to corrupt regimes in latin america when it comes to this investigation, he's accused the doj of leaking sensitive details. he says the only reason to leak it is to create a narrative for political purpose. when information gets shared with congress, as you know, the accusation is, it will get leaked. so, a, it looks like you're losing that bipartisanship. b, if you brief congress, isn't it going to leak further and worsen? >> the record of our intelligence committee of

keeping secret, secret, that's why the intelligence community shares information with us. remember, this was the committee bipartisan that did the russian -- >> you know your oversight capability, many would argue, including former heads of counterintelligence, fbi, the line is drawn when it's an active investigation. >> we do not -- i do not want any kind of insight into an active investigation by the justice department. i do want the damage assessment of what would happen to our ability to protect the nation. here we are 21 years after 9/11. if classified secrets, top secret secrets are somehow mishandled, i pointed out earlier, people could die, sources of intelligence could disappear, the willingness of our allies to share intelligence could be undermined. i think we need that assessment to make sure -- >> which you will get, but it's going to take some time. to that point, because it's so sensitive, because the country is so divided, because you already have in many ways a target being put on the back of

law enforcement, isn't it more important to get it right, to be deliberate and not to be fast here? i want the details just as much as you do. >> listen, i do not think we should have as the intelligence committee, you know, a briefing on the ongoing investigation. what our responsibility is to assess whether there's been damage done to our intelligence collection and maintenance of secrets. that is a damage assessment that frankly, the judge in florida has said could continue >> before november? >> listen. once we get clarification from the judge in florida, again, i don't think we can cherry-pick what part of the legal system we like or dislike. i have trust in our legal system. i may not agree with the decision of the judge in florida but i respect our department of justice. i respect the fbi. i think they are trying under extraordinarily difficult circumstances to get it right and we owe them the benefit of the doubt. >> senator, thank you for coming on. i know we're going to continue

to track this and any potential impact to national security. >> thank you, margaret. we turn to retired marine general frank mckenzie, in charge of u.s. central command. last august he led the u.s. withdrawal from afghanistan and we welcome him now. good morning to you, general. >> good morning, margaret. it's good to be here. >> i know you were at the pentagon when it was attacked on 9/11. a we just laid out, that really came full circle as you executed this withdrawal. i wonder how you make peace and make sense of all that was lost? not just the 2,400 service people who lost their lives in that conflict, but those who survived, who continue to deal with loss, and look at an afghanistan that is once again under the control of the taliban. >> well, margaret, over the

21-year arc from the 9/11, and i was in the pentagon, until we came out last august, we prevented a major attack occurring on the united states. the cost was not cheap, as you noted. we lost a lot of brave young americans. our coalition partners lost a lot of their soldiers. and, of course, the afghan people paid a steep price for that. it wasn't a cost-free proposition. we did manage to prevent another major attack from occurring against the united states during that period of time. i'm still processing what it means at the end. it would be presumptuous to say it bothers me more than those who lost a loved one at some time in afghanistan or one of the other theaters where we carried on a battle against this relentless foe. >> i know you have since leaving your position shared that you advised president biden not to draw down to zero, to leave a residual force of 2,500 troops in afghanistan. as commander in chief to keep his own counsel and reject the

advice of his military commanders. if you felt so strongly, why didn't you resign? >> i had the opportunity to give advice to the president. he heard my advice. it was heard thoughtfully. that's all a commander should expect to do under our system. once the president makes a decision, for combatant commander like me, the chain of command is very short. it is secretary of defense and it is the president of the united states. and once a civilian leadership makes a decision, even though i might disagree with that decision, it is my moral responsibility to execute that order, to resign is not in -- is not in the history, it is not something that u.s. officers have typically done. and it sends a very bad signal. it is a political act by an officer who must need and must be and remain apolitical. even if you disagree with the order, as long as the order is legal, you need to follow that order. if we do anything different, it would be very dangerous to the republic. so, while i gave advice, my

advice was not followed, i executed that order as well as we were able to do. i just note the president makes decisions based on many factors. my recommendation in central command or are several factors it the president had to weigh and there were other factors he had to weigh as well, and i'm aware of that. >> do you think given your assessment of the threat, that the united states is paying enough attention now to the middle east and to afghanistan? >> well, i hope that we are. i think that we have very, very limited ability to see into afghanistan right now. i've said i think we've got certainly less than 2% or 3% of the intelligence capability we had before we withdrew. our interest in afghanistan is preventing al qaeda or isis from regenerating and being able to conduct an attack on our homeland or the homelands of our friends and partners. and our ability to do that has certainly been gravely reduced. now, the fact that we took a

strike against zawahiri and that was a very good and proper action, that's good news. i would note this one strike in a year. and i would just come back, i would be careful about drawing conclusions about our ability to operate effectively in afghanistan in a counterterrorism sense based on that single operation. >> you're talking about the cia drone strike that took out the leader of al qaeda, al zawahiri in july. but the administration would point to that and say, look, we can counter the terror threat without a military footprint. so, are we at the right balance right now of keeping the homeland safe? do you agree with their assessment that isis and al qaeda do not presently pose a threat of being able to carry out an attack here? >> when i left -- when i left active duty, it was our assessment that if we left afghanistan, if the afghan

government fell, if the taliban took over, then over a period of time both al qaeda and isis would be able to regenerate. that is still my opinion today. you know, it's going to take a little time for them to do that, but i think what's most concerning about the cia strike you mentioned is the fact that he was living in very good accommodations in downtown kabul. that should give us all pause. and also speak directly to the ill intense of the taliban in negotiating with us as we work with the doha agreement, which was the attempt to find an end to the war in afghanistan. i think it's a manifest example of their inability to keep their word. >> what i hear you saying there is that the trump administration bears responsibility for the deal it brokered with the taliban, the doha agreement? >> so, i think the reason that we left afghanistan and the reason the afghan government fell was that two presidents, president trump and president biden, both had very high objective to leave afghanistan.

you had continuity of purpose across two administrations. the doha agreement, had we held taliban to the conditionality that was a critical part of it, it could have been a useful vehicle for moving forward, but we did not hold the taliban to the conditions they said they would observe. that -- because of that, no agreement's going to be good. >> the biden administration has not released any public version of an after-action report of what went wrong. this was a big black eye. i don't have to tell you that, how this withdrawal happened. do you think this assessment should be made public? and does the fact it is not public now suggest to you that any politics is at play? >> i don't know, margaret. i would tell you that i participated before i left active duty in that after-action review. we did a number of those inside centconn and i was interviewed.

i think it's a good thing to release as much of that review as you can. obviously, there will be sensitive intelligence components to that, but i think you could probably exsize some of those and i think the american people want to know what happened and i think that's a reasonable thing to do. >> we'll continue to press forward for that and thank you for your insights today. retired general frank mckenzie. we'll be back in a moment with more "face the nation." stay with us. y managers.

morning in england as queen elizabeth ii begins her long journey home. this morning we saw her oak coffin covered with the royal standard of scotland beginning its slow six-hour journey from balmoral castle to edinburgh. there were tens of thousands of people lining the road in tribute to the queen. the coffin will rest in the throne room of the hollyroodhouse, the official residence of scotland, and then king charles iii and queen consort, and it moves to st. giles. the new sovereign tour the countries that make up england, including northern ireland, before next monday, on september 19th. there has been much said about the people's sentimental attachment to the monarch. the commonwealth's matriarch. her reign of 70 years, and a living link to world war ii. it's, perhaps, fitting that the

how strong the reaction has been? >> well, could i start, margaret, by also expressing my condolences to the american people on the anniversary of 9/11. as you say, that is what the queen said. she also asked that the british institutions fly the american flag after 9/11 and on the 10th and 20th anniversaries. i think it's very good the mayor and others have put up the british flags. it's very kind of them. we appreciate it very much. yes, i think we were a little bit surprised by quite how many americans have rallied, have come to the embassy to pay their respects, have sent us messages. we were honored by the president coming to the embassy, the vice president and secretary blinken. this is what close allies do. they support each other. nevertheless, it's a very moving thing to see. >> and president biden, other world leaders, have said they will come to the united kingdom for the funeral next monday. i want to take a quick break here and come back because we have a lot to talk about.
