High school students in Nashville walked out of their classrooms Friday as a way to call for more gun control.
Today marks 19 years since the horrific shooting at Columbine High School in Littleton, Colorado, where 12 students and a teacher were killed. Many participating in Friday's march will also hold 13-seconds of silence for the families of those victims.
Students at MLK Magnet and Hume-Fogg were expected to march in support of the National School Walkout Movement.
At 9:15 a.m., students began walking out of their classrooms and marched to Public Square Park, where a rally got underway.
There, the names of those killed in the Columbine shooting were read aloud.
Tennessee lawmakers Rep. Craig Fitzhugh, Rep. Mike Stewart and Sen. Jeff Yarbro also addressed the crowd.
A town hall in the Cordell Hull Building is planned for 4 p.m.
In the wake of the mass shooting at a Florida high school, many students -- including current Columbine students -- say not enough has been done to help prevent mass shootings.
The movement also encourages young people to push for legislation at the state level if Congress doesn't act. They have five specific things they want lawmakers to accomplish in the next year:
- Background checks for every gun sale
- Waiting periods on gun purchases
- Banning bump stocks
- Requiring safe storage of guns
- Take guns away from domestic abusers.
While there hasn't been major congressional action since the Parkland massacre, some cities and states have toughened gun control.
