During his broadcast he recalled a conversation he had six years ago with the children and grandchildren of the inventor of the AR-15, Eugene Stoner, who told Tony at the time that Eugene invented the machine "solely as a military grade weapon" and that he would be "horrified and sickened by the attacks".

The teenage suspect also had a handgun and high-capacity magazines, according to investigators. He was killed by law enforcement after his attack.
Ten children who were killed in the attack have been named, including Uziyah Garcia, Alexandria Aniyah Rubio, Amerie Jo Garza, Makenna Lee Elrod, Xavier Javier Lopez, Jose Flores, Navaeh Brown, Annabell Guadalupe Rodriguez, Alithia Ramirez and Ellie Lugo. Eva Mireles and Irma Garcia, both teachers at the school, also died.
Tony shared the message from outside the school where 19 children died
The horrifying attack left the world in mourning and saw many call for stricter gun control laws in the US.
"Firearms are the #1 leading cause of death for American children and teens," shared Amy Schumer.

This is yet another tragic example of how pervasive this public health crisis is in our country. @everytown."
Selena Gomez is from Texas and also penned a heartfelt and sad social media post.
