Sen. Lindsey Graham (R-S.C.) said last week that former service members should be tapped to help secure schools.

“We have hundreds of thousands of well-trained former military members who could bring a lot to the table in terms of school security,” he said Friday in a Twitter thread. “ROTC instructors with firearms training should be allowed to possess weapons to enhance school security.”

He continued to say he “will be working to create a certification process that allows former military members to go through school security training and become available to school districts throughout the country,” Graham tweeted.
