Hundreds of high school students in Nashville, Tennessee, rallied in favor of tougher gun laws following a deadly mass shooting at The Covenant School.

The shooting that took the lives of three staffers and three students has become a rallying cry for progressives in favor of stricter gun laws.

Many students walked out of their classrooms and held protests, demanding gun reform. Meanwhile, Governor Bill Lee proposed increasing school security measures statewide and considering implementing red flag laws, similar to those enacted in other states, including Florida.

The rally and student walkout were organized by March For Our Lives, a national nonprofit advocating against gun violence that emerged after the Marjory Stoneman Douglas High School shooting.
