Lawmakers in Tennessee passed a measure Tuesday that would allow school staff to carry concealed handguns on school grounds, sending the bill to the governor a year after a shooter opened fire and killed six people at a Nashville school.

The Tennessee House cleared the legislation in a 68-28 vote. The state Senate, which is also controlled by the GOP, passed the measure earlier this month.

Republican state Rep. Ryan Williams on Tuesday said the bill would bolster school safety.

“I believe that this is a method by which we can do that, because what you’re doing is you’re creating a deterrent,” he said on the House floor.

Under the legislation, faculty and staff members who wish to carry a concealed handgun on school grounds would need to complete a minimum of 40 hours of approved training specific to school policing each year.

Protesters could be heard in the gallery on Tuesday chanting, “Blood on your hands,” during the floor proceedings.

Democratic state Rep. Bo Mitchell pushed back on the measure, referring to last year’s Covenant School shooting in Nashville when three children and three adults were killed.

“This is what we’re going to do. This is our reaction to teachers and children being murdered in a school, our reaction is gonna throw more guns at it. What’s wrong with us?” Mitchell said on the House floor.

State Sen. Paul Bailey, a Republican who sponsored the bill in the upper chamber, did not immediately respond to a request for comment Tuesday.

A spokesperson for Republican Gov. Bill Lee did not immediately respond to a request for comment on whether he planned to sign the measure. He can either sign the bill or allow it to become law without his signature. Lee has not vetoed any legislation as governor.
