Tennessee teachers and staff will be allowed to carry concealed handguns on public school grounds under legislation signed into law by Gov. Bill Lee on Friday.

Lee, a Republican, had announced his support for the proposal just the day before while flanked by top Republican legislative leaders who had helped shepherd the bill through the GOP-dominant General Assembly.

"What’s important is that we give districts tools and the option to use a tool that will keep their children safe," Lee told reporters.

As the idea of arming teachers began to gain support inside the General Assembly, gun control advocates and families began swarming to the Capitol to show their opposition. During the final vote, protesters chanted "Blood on your hands" and many members of the public who oppose the bill harangued Republican lawmakers after the vote, leading House Speaker Cameron Sexton to order the galleries cleared.
