Ohio’s House Bill 99 has gone into effect, which means teachers, principals and school staff are now permitted to carry firearms on campus and in classrooms.

Republican Ohio Gov. Mike DeWine signed the bill into law on June 13, the Washington Examiner reported. It went into effect on Monday.

“Our goal continues to be to help our schools, public schools, parochial schools, private schools, to have the tools they need to help protect our children,” DeWine said after signing the bill, the Examiner reported.

“Working together, we have come a long way to improve school safety in Ohio over the last decade, and we must continue this progress. We have an obligation to do everything we can every single day to try and protect our kids,” DeWine also said in a statement after signing the bill.
