Live updates: Texas elementary school shooting

David Hogg, an activist and survivor of the Marjory Stoneman Douglas High School shooting, told CNN on Wednesday that “there is no way to process what has happened” at Robb Elementary School.

Hogg was hiding in a closet during the shooting at his high school in Parkland, Florida on Feb. 14, 2018; 17 people were killed.

“The reality is if I’m just talking about this, and Congress is talking about this, after there’s been the equivalent of another Sandy Hook or another Parkland or another Buffalo … we are failing our children,” Hogg told CNN’s John Berman .

Hogg said he spent a few days with victims of the recent mass shooting in Buffalo and says there is still “shock” in that community.

“The only way we’re going to be able to successfully address this is why we’re working together as Americans to create a more perfect union, because right now, our union is incredibly imperfect and deeply broken because we can’t protect our most valuable asset, which is our children, “said Hogg.

The March for Our Lives co-founder told CNN his message for action on gun violence is “first of all vote and second of all, show up at your state legislature every year demanding action on gun violence. Not just around how somebody gets a gun , but why they pick up a gun in the first place. ”

“If we do that, mark my words, we could cut gun violence in half in a decade,” Hogg said.
