Sen. Kamala Harris (D-Calif.) blasted the Trump Administration’s proposal to arm teachers following a national call for gun control legislation led by student-run organizations.

At a Judiciary Committee hearing on gun violence on Wednesday, Harris said she was troubled by President Donald Trump’s plan to have firearms in the classrooms.

“As a career prosecutor, I have worked with many communities where children go to sleep each night hearing gunfire,” Harris said. “What we’re proposing is that those children, remember Sandy Hook, we’re talking about six and seven-year-olds, so children are supposed to go to school and look at the front of their class at their second-grade teacher and she is going to be strapped with a gun. I don’t understand how that makes any sense.”

Today’s judiciary hearing marked the one month anniversary of the Marjory Stoneman Douglas High School shooting, where 17 people lost their lives.

On Wednesday, thousands of students walked out of classrooms across the country to call attention to gun violence and call for stricter gun laws.

Harris also expressed concern over what would happen to children of color if teachers were to be armed.

“I also have a concern when we talk about this, of the impact of having armed teachers as it relates to African American and Hispanic students,” she said. “There’s an overwhelming body of evidence that shows that harsh disciplinary protocols disproportionately impact children of color.”
