A Fairfax County school board member is urging federal and state officials to enact stricter gun control measures following one of the country’s deadliest school shootings.

Ryan McElveen, an at-large board member, invited community members in a tweet Tuesday morning to “stand in solidarity with us in memory of all the lives lost to the plague of gun violence and to call on our legislators to act.” He said he plans to put forth a resolution Thursday at a school board meeting calling on lawmakers to better regulate access to firearms.

“When it’s an issue like this, where a school board can only do so much, it’s really incumbent upon us on behalf of the community to be their voice,” McElveen said in an interview. “There will be a big crowd to support the resolution and I am hopeful this will be a galvanizing moment for the community.”

The resolution also calls on legislators to increase mental health support and funding for public health research on issues related to firearms. The Northern Virginia school district has worked to bolster mental health support for students in the last six years, helping students manage stress and promoting health and wellness following a rash of suicides at Langley and Woodson high schools, McElveen said.

The 189,000-student school system, along with other districts in the Washington region, tightened security measures last week after 17 people were killed in a shooting at Marjory Stoneman Douglas High School in Parkland, Fla.
