>> brennan: today on "face the nation." the students of marjorie stoneman douglas high school march on washington leading more than 200,000 in the largest youth-led protest since vietnam. >> welcome to the revolution. >> brennan: across the nation and around the world, thousands and thousands more came out to voice their support for tougher gun laws. but will washington lawmakers get the message? last week congress enacted some new school safety measures and made modest changes to the background check system for gun purchases. is this all they can get done in an election year? it was another head turning week at the white house. on friday president trump first tweeted out a threat to veto a massive spending package then changed course and signed it

just four hours later. saying he wanted to protect military spending increases. >> i say to congress i will never sign another bill like this again. i'm not going to do it again. >> brennan: the disagreements with national security advisor h.r. mcmaster led to his ouster he'll be replaced by ambassador john bolton. presidential attorney john dowd is also out mr. trump said he'd like to be interviewed by special counsel robert mueller but dowd reportedly didn't want him to. worst week in two years as concerns about a trade war intensified after the president's steel and aluminum tariffs went into affect. $60 billion worth of tariffs on chinese imports. top democrat on the senate intelligent committee mark warner will be here and speak with iowa republican joni ernst about the impact of a trade war on her home state. and the stoneman douglas student

activists who led that rally in washington join us. we'll also have plenty of political analysis, it's all ahead on "face the nation." good morning, captioning sponsored by cbs welcome to "face the nation." i'm margaret brennan. 40 days ago 14 students and three teachers were killed in a shooting rampage at marjorie stoneman douglas high school in parkland, florida. yesterday survivors led a march on washington. cbs news estimates the crowd topped just over 200,000 supporters. they were joined by protesters in more than 800 cities in what was billed as the march for our lives. the goal, action in washington and at the state level for tougher gun control measures. >> our elected officials have seen american after american dropped from a bullet. instead of waking up, they have been hitting the snooze button we're here to shake them awake.

>> brennan: appearances were limited to young leaders and victims of gun violence. 9-year-old yolanda renee king the in spiring speech her grandfather delivered almost 54 years ago. >> i have a dream that enough is enough. [ cheering and applause ] and that this should be a gun free world. >> brennan: in atlanta another hero of the civil rights movement weighed in. >> we're never too young. we're never too old to march. >> brennan: we begin today with virginia senator mark warner he's the top democrat on the intelligence committee he joins us here. senator a lot to talk to you about but want to speak first about this march on washington that we saw. march is over, congress is on break. you did see tucked into that spending bill some tightening of background checks and some

funding for school safety. is this all we're going to see before november? >> i hope not. there was finally some incremental movement but in this era of fake news and disinformation, to see the genuineness of all those young people, i think this time it's going to be different. their demand for sensible gun control, i think we can actually get it done. i hope they will keep that energy alive and moving forward. it was -- i think of the was democracy in action not just in washington but all across the country. >> brennan: you voted against an assault weapons ban in 2013 then in 2014 you voted against cap on high capacity magazines. they're asking now to restrict those things, have you changed your position? >> i think it's time to change our positions and reexamine. i'd always been in favor of universal background checks particularly after sandy hook but it's time for us to have a legitimate debate about restrictionsq

and assault weapons. you get into definitions but the basic notion of these weaponized military weapons need to be off our streets. even the trump administration took some small step on bump stocks. i think it's time and i hope these kids continue to press. >> brennan: what would you recommend to them in terms of where they focus their energy now? >> well, i think the fact that they're going to call for a walk out in april is appropriate. i think the most important thing they can do, register and vote. end of the day, that's the way you change democracy. >> brennan: you have about seven months to go until the congressional elections, you and homeland security have been looking into election meddling they found that russian agents targeted voting systems in 1 states ahead of the 2016 election. how do you stop that from happening seven months from now? >> we are behind and it was

remarkable that it took department of homeland security this much time to identify those 21 states. and the thing that bothers me the most -- >> brennan: publicly disclose them. >> even they took them eight months to even tell the actual states. they had this ridiculous excuse that the top election official would not have appropriate security clearances and what i think is an embarrassment and a bit disgraceful that this president still has not called out election security, has not told his top law enforcement and top intelligence agents to make this a priority. he clearly didn't raise it on his call with vladimir putin where he instead congratulating what john mccain called a dictator and chamois lex. our people, we came up with legislation that said let's make sure there's thatxdñi paper tral after every paper ballot, after every vote, make sure there's

better sharing of information, in the spending bill there is about $386 million to help states get their act together because we're already in primary season. >> brennan: will that make a difference in november? >> it w but even more of a difference if this white house would actually realize this is a national security concern and what the russians did in the 2016 elections in terms of dissention, weaponizing information, has not stopped and many ways has continued unabeted since that time. >> brennan: this week facebook revealed that russian propaganda group created about 500 fake accounts running adsçó around te election spent $100,000 on divisive acts, can you possibly legislate a fix to prevent that kind of thing from happening again? >> first of all facebook unfortunately -- all social media, were really slow to respond. i called this out in december of 2016, at first they kind of blue

me off and others off who were raising these issues. >> brennan: mark zuckerberg a apologizing. >> it's not just the paid ads that's a small piece it's the fake accounts that literally touched close to 145 million americans. that's just with fake accounts. the next wave of technology will be able to have your image with words coming out of your mouth that may not be said or your face put on somebody else's body in terms of next wave of technology. we have to get our arms around this. i think mr. zuckerberg needs to come and testify before congress not just put an advertisement in a newspaper he said he would if he was the right guy. he is the right guy. he can't send a staff. when i'm called upon an issue, it's my name on the door, you wouldn't wouldn't take a staff member on your show representing me. he needs to come, testify before congress and explain how they're going to work with us to both protect privacy through 50 million facebook accounts that

were used by this sketchy firm cambridge ant lit particulara. >> brennan: what you're talking about there is the firm that scraped some of date that people didn't know their personal information was go be to be used or manipulated in the process. steve bannon, former white house strategist also served at one time on the board i believe at cambridge, he says he knew nothing about the facebook mining. is that a credible denial to you? >> i would like to -- love to have that kind of interview with steve bannon. i'm not sure. >> brennan: do you plan to? >> we hope to, yes we do. what we know about -- >> brennan: on the cambridge -- we raised the question of micro targeting as early as march of '17. there's something a little fishy about this firm. we now know that the ceo reached out to julian assange the

wikileaks leader about hacked e-mails. we know this company worked with russian oil company who was looking about election data in america. the big question is, cambridge analytica how much they helped the trump campaign micro target. just helping the trump campaign are were they utilizing some of the russian misinformation and disinformation, there are legitimate questions that need to be answered. why our investigation needs to continue and the mueller investigation needs to continue. >> brennan: senator warner, thank you for your time. >> thank you. >> brennan: we want to turn now to iowa republican senator joni ernst she joins us this morning from omaha, nebraska. senator, good morning. i want to ask you about impact of those tariffs on your home state but first off i want to ask you because you are one top ten recipients of nra funding in the senate, your image was being held up by some of the protesters at the rally here in washington yesterday. i wonder, how you are responding

to these young activists who are calling for gun control? >> well, margaret i want to push back on that because i myself don't receive funding from outside organizations other than what the smaller donations that might come from pacs, many outside organizations will run advertisements without the consent of candidates. they will run advertisements for candidates, against candidates. i have no control over that, my campaign has no control -- >> brennan: you're separating yourself from the nra by saying that? >> no, i am not separating myself from the nra. i would state that there are lot of outside organizations that cannot coordinate with candidates or their campaign, that's against election law. so they will do what they want to do. but i will say that i am a supporter of the constitution. i'm a supporter of our bill of rights. we have many rights that need to be upheld in the united states.

i would say that i have been a second amendment supporter my lifetime. i was a member of the nra long before the nra knew of joni ernst private citizen in iowa. >> brennan: your advice to those young activists? >> i would say, i appreciate the fact that they have the right to peacefully protest. and inform the government of what they believe is the right path forward. i think every citizen has the right to do that. but every citizen as long as they are law abiding also has the right to exercise their second amendment right. what we don't want to do as a nation is start stripping rights away from law abiding citizens. i think that the status quo is not okay. that's where these young demonstrators are speaking out against. we do have to find a way forward, but simply stating we need to get rid of other people's rights is not the right way forward. >> brennan: you have said

that -- in part to the concerns of a trade war, iowa is a major exporter to china. what will these new tariffs the president announced on china and other countries do to your home state? >> well, nobody wins in a trade war, margaret. especially been the chinese officials, media reporting that they will retaliate against american agricultural products namely pork and soybeans. china has purchased 14 billion dollars worth in 2016 of american soybeans. roughly 60% of our soybean crop does go to china. if they start retaliating, we will see significant impact very detrimental impact not just in iowa but across the midwest as well. >> brennan: the white house has not yet detailed exactly what these tariffs on china are going to look like, are they talking to republicans like yourself? >> well, there are talks.

i have spoken on trade issues directly with the president before and i hope that we can continue those conversations, in the future. i know that congress has the u.s. trade representative, they were asking him questions it was concerning that he came back said, yes, it will be painful basically for the american farmer. but that's a small price to pay. i disagree. if we want to close up trade deficits we need to do it in a smart manner, let's allow american agricultural to close that gap, let's open up additional markets not close them off to agricultural goods. >> brennan: you also sit on the armed services committee and late friday the president did announce that he was changing hisok position but still banning essentially transgender people from serving in the military. do you support that? >> well, i support allowing those transgenders that can

serve i believe they should serve. we do want to make sure that they meet physical requirements. we can't wave that. that is true across any demographic within our military. making sure that they are physically fit and they meet the mental standard. but i've asked transgenders myself, if you were willing to lay down your life beside mine i would welcome you into our military. again, there are standards that have to be met i will support the president and the administration on making sure that standards are met. but if there are transgenders that meet those qualifications certainly i would gladly have them serve in our united states military. >> brennan: will you ask the white house to change its position? >> well, i think that the white house has done very studied analysis of how we have the best qualified people coming into the military and so i'm happy to have those discussions with the administration. but again making sure that those

standards are applied fairly across the spectrum of every citizen that wants to join our united states military. >> brennan: senator thank you for joining us this morning. >> thank you, margaret. >> brennan: we'll be back in one minute with five of the students who put together the march for our lives rally yesterday. when this bell rings... ...it starts a chain reaction... ...that's heard throughout the connected business world. at&t network security helps protect business, from the largest financial markets to the smallest transactions, by sensing cyber-attacks in near real time and automatically deploying countermeasures. keeping the world of business connected and protected. that's the power of and. another anti-wrinkle cream in no hurry to make anything happen. neutrogena® rapid wrinkle repair works in just one week. with the fastest retinol formula to visibly reduce wrinkles.

streaming down her face honoring those who were lost. >> since the time that i came out here, it has been six minutes and 20 seconds. the shooter had been shooting and will soon abandoned his rifle, blend in with the students as they escape and walk free for an hour before arrest. fight for your lives before it's someone else's job. >> brennan: today we welcome five of those student activists, jaclyn corin, brian deirsch, delaney tarr and cameron kasky and emma gonzales. what was that like watching yourself on tape? >> that was kind of weird. in the moment, it feltw3ñuz good to finally say it because of course it's really stressful the whole day you're waiting i was the last one. it had been building up, it felt so good to finally say it. >> brennan: cameron, didn't the overarching policy goal here, what are you asking for here in

washington? >> here in washington we're demanding an assault weapons ban, we're demanding prohibition of sales of high capacity magazines and we are demanding universal background checks which is something you'll see from the polls pretty much the entire country is behind yet we've seen nothing of it. >> brennan: you did have a statement from the white house yesterday where the president said he appreciated you all celebrating your first amendment right. pointed that his administration banned bump stock, stop school violence act which authorized grants to increase school safety and some actions to improve background checks records. do all of you consider that progress? >> you know, the school act doesn't mention the word "gun" once. obviously school safety is important but it isn't just schools, people need to understand that it's a public safety issue not a school safety issue. so we need to fight the problems in the core which is guns.

>> you'll notice in all these shootings not just one in schools, in movie theaters, airports, churches, nightclubs, there's no specific mental health issue that you can tie to every single one. only thing you can tie to every single one is weapons that belong in the hands of soldiers, in the hands of citizens who are untrained. >> brennan: do you think more than 200,000 people came out agree with all of the points that you have been asking for here? >> i mean, i do believe that even if there is some difference in opinion on small issues ultimately the fact is that all of these people come to the largest march on washington because it is the largest march on washington they were there because they support the cause, they support safety. they support our lives and protecting our lives that's what matters, if there is some small issue they stand with us. that's what matters. >> i mean, i can say from firsthand as i said we need to arm our teachers, i heard booing from the crowd. i heard they were clearly not behind the message like that

when i turned it around to say this they need to be armed with pens, pencils were paper and money they need to support themselves, you could see the crowd regain support, regain -- there were -- >> brennan: few people that -- confused a lot of people. the crowd was very like minded they all were on the same page that they just didn't want to see all these innocent children die. >> brennan: now, you all are not just rallying here in washington you've been pushing in your home state of florida. but florida did just decide that they're going to allow training of some teachers to be armed. some districts can opt out. do you feel like you lost the argument back at home? >> not at all. as a matter of fact in florida they passed a bill that raised the age to 21, added three day waiting period. these are very small steps in the right direction. but i think you'll notice if all teachers are required to be armed or several teachers per building, many teachers will quit. a teacher said if there was armed teacher in their building trained or not they would be out

of there. arming teachers put kids more in danger and puts the teachers in more danger. >> brennan: were you surprised see action in your home state before you saw it in washington? >> yes. very much so. because rick scott is funded by the nra, yes, our governor. the nra in turn sued the state of florida that's obviously step in the right direction. he's running for senator that might have been a reason why he did it to get the popular vote but -- >> brennan: you're cynical. you're political gaming here. you're student class president, right? >> yeah. >> brennan: when you're looking at this political activism right now are you inspired that you want to become politically involved after you graduate? >> 100%, yeah. >> brennan: run for office yourself some day? >> maybe so. i wasn't politically involved but i've learned so much in matter of month and a half it's intrigued me. >> brennan: we're going to he that a break in few seconds we

don't have much time here then we'll come back and finish the conversation. but quickly, can you raise your hand if you're going to be voting in november, are you eligible to vote? >> my birthday is in october i hit the mark. >> i can't vote in the next election but for one vote i can cast. >> brennan: do you have congressional candidates who have signed on to your agenda? >> we're not endorsing any political figures. >> brennan: are they endorsing your platform. >> we endorse ideas not people. >> absolutely, we love that, we want support but we're not endoorsing any particular candidate. >> brennan: we have to take quick short break but all of you to stay with us all of you at home as well. we'll be right back. i'm not a bigwig.
