Were see them gathering getting ready to go right there in they are not alone. Students all across florida staging walkouts in solidarity and abcs dan harris is in tallahassee with the teens getting ready for their rally. Good morning dan. Reporter michael good morning. Coming to you from a civic center where the kids spent the night on cots eating breakfast behind me right now as you might be able to see. Sooners going to walk over to the State Capitol where they have a long series of meetings with everybody from the speaker of the house to the attorney to the governor. When you talk to their kids their passion, pain idealism its all palpable but it is already running head first into hard legislative realities here in this gunfriendly state. 100 young people carrying sleeping bags and pillows as they boarded buses on an extraordinary lobbying mission. Just days after surviving one of americas worst School Shootings. The first busload of parkland students have arrived and theyre being greeted by a very large, enthusiastic and sympathetic crowd of local high School Students. Were fighting for our friends we lost and for the future of kids were going to have. Reporter while on the road from parkland to tallahassee these young activists received some tough news. The motion is not adopted. Reporter florida legislators voted against even considering a ban on semiautomatic rifles some parkland students were in the gallery for the vote reacting with tears. The next step on someone with an Assault Rifle here in florida is going to be on them. Reporter as you know lawmakers voted against even considering a ban on semiautomatic rifles. What is your reaction to that. It was a big punch in the gut because the itll be a week tomorrow since this happened and already theres another roadblock in front of us. This is something i think applies to everyone around the country. We dont were not focusing on the students. Las vegas, this has been an issue long present in our country. Has it been tough on you psychologically to go from surviving one of the worst School Shootings in American History to diving into what is really a tough political fight where youre taking some criticism. It is a way of grieving i guess and im doing it for the two friends i lost because i know this is what they would have wanted. We were the ones who were locked in closets for hours not knowing if we were going to be okay like maybe were not necessarily activists on the politics side but we know theism packs it can have on anyones life. Were still waiting to wake up. I know for me this is the way that were grieving. How confident are you really that your school will be the last shooting. We have an energy thats far from being over. Were going to keep fighting. We have the whole world backing us and supporting us. Reporter these kids are well aware, though that they do have detractors among pro gun activists who call them tools of the liberal left but on the ground they received an enormous outpouring of support. For example, when they arrived here at the civic center and went to their cots to go to bed they found goody bags filled with snacks and homemade cards and notes from local teachers and students. Michael. And, dan, its possible that florida might step in on a state level if congress doesnt step up but has change on a state level worked in Something Like this in the past . Reporter so this is tricky and a little bit controversial any time you talk about gun control legislation but it appears from the numbers that states with tougher gun laws do have lower levels of gun violence, for example, in connecticut after sandy hook they passed some tough, new laws and gun violence did go down. Critics say, though that may be because the overall crime rate went down. Dan, i guess the sad commentary but these students weve seen all over the last week now getting smeared online. Reporter yeah so these kids are well aware of the trolling that has been directed toward them. And some darker corners of the internet there are charges that these kids are actually actors are 0 quote unquote crisis actors. These kids deny that. Theyre not super defensive about it and think its absurd and even their senator marco rubio came forward to say its flatly faust. Overall when the kids look at their social media feeds which they do quite frequently they see an outpouring of support which gladdens them. President trump is now signaling his support for some modest new measures strengthening background checks a First Step Towards stopping those bump stocks. Jon karl joins us now and the president is going to hear directly from some of those affected by gun violence today.

Meanwhile, Sarah Sanders is now walking back the president s tweet that suggested the fbi failed to stop the Florida Shooter because, quote, they are spending too much time trying to prove russian collusion with the Trump Campaign. The president doesnt really think that the fbi failed to stop the parkland shooter because it was too involved with the russia investigation, does he . I think he was speaking not necessarily that that is the cause, i think we all have to be aware that the cause of this is that of a deranged individual. Did he mistweet when he said that. Hes pretty direct. He says this is not acceptable. They are spending too much time to i think hes making the point we would like our fbi agencies to not be focused on something that is clearly a hoax in terms of investigating the Trump Campaign and its. Reporter President Trump has often boasted about being the most pronra president ever and although he is looking at new gun restriction, those mentioned in the piece, hes also george looking at proposals that would mean more guns in schools includeing arming more stevers. That have been endorsed by the nra.
