Texas school shooting: Lawmakers, others react to latest case of mass gun violence

An 18-year-old gunman killed 15 people Tuesday at an elementary school in Texas, authorities said. The victims included 18 children and one teacher. The gunman was also shot dead.

The shooting in Texas came less than two weeks after a gunman opened fire at a supermarket in Buffalo, New York, killing 10 Black shoppers and workers in what officials have described as a hate crime. Across the country that same weekend, someone opened fire in a California church, critically injuring four people and killing one. 

It was the deadliest shooting at a U.S. grade school since the shocking attack at Sandy Hook Elementary in Newtown, Connecticut, almost a decade ago.

Lawmakers and activists, and others around the country immediately spoke out about the latest scene of violence. The White House proclaimed flags would be flown at half-staff to honor the victims.
