"Starting the night of the attack, Kasky and a handful of his classmates took to social media, demanding stricter gun control laws and the right to be able to go to school without the fear of being killed. As they typed and posted, the hashtag #NeverAgain went viral. "I found myself frantically Facebook posting. It was what I knew how to do," he says. "The next morning I was getting all these calls from reporters." The same thing happened to his friends. As well as doing broadcast interviews, Kasky wrote online comment pieces and - a week after the attack - he took part in a televised town-hall event. Standing in front of a large crowd of his peers and neighbours, he confronted Republican Florida Senator Marco Rubio over the money he had received from the National Rifle Association. "Senator Rubio can you tell me right now that you would not accept a single NRA donation in the future?" he demanded. The room exploded into chants and cheers. Kasky looked stunned and overwhelmed. He had just put one of the nation's most prominent politicians on the spot, live on national television. As momentum gathered behind the young campaigners, Kasky co-founded the group March For Our Lives and set about organising a demonstration in the nation's capital. Six weeks after the attack, on 24 March 2018, hundreds of thousands of people gathered in Washington DC for the March For Our Lives protest. The Parkland students demanded a ban on assault weapons and high-capacity magazines, and stricter background checks for those wishing to buy guns."
