Thousands turn out for March for Our Lives protests across the U.S. and the world, to demand stricter gun laws in the aftermath of the Parkland school shooting that left 17 dead, including 14 students and three teachers.

The students, including 11-year-old Naomi Wadler, Martin Luther King Jr.’s granddaughter Yolanda Renee King, David Hogg and many others are putting politicians on notice that they will be heard at the ballot box. David Hogg and several other teen speakers called out Donald Trump and Sen. Marco Rubio as selling out Americans to the National Rifle Association.
