Hundreds of thousands gathered in Washington and in cities around the country Saturday for March For Our Lives, the event organized by the survivors of the shooting at Marjory Stoneman Douglas High School in Parkland, Florida. The aim of the event is to end mass shootings in schools and push gun reform legislation.

The program in Washington will include speeches by Stoneman Douglas students, as well as performances by Lin-Manuel Miranda and Ben Platt, Miley Cyrus, Arianna Grande, and more.
