ROCKFORD, Ill. (WIFR) -- Students across the U.S. and the Rock River Valley walked out of school Wednesday, March 14, for the biggest demonstration of student activism for tighter gun control measures.

About 100 students at Rockford East High School marched out of class at 10 a.m., one month after the school shooting in Parkland, Florida. The students walked out to let their voices be heard and demand stricter gun control laws from legislators.

"This is not political for these kids; this is about life or death. If you believe in safety for these kids, then you have to support them, whether you're a Republican or Democrat, you support them and their message," said Melissa Champion, an adviser for the student walkout.

Chanting "enough is enough,” and "we want change, keep your money,” the students made their message clear.

"We're hoping that they actually do something and change this stuff because there have been so many of these things happening and all they can do is apologize and not decide to change any of the regulations. I really think that we should do something for once and change that," said Indira Gallegos, a junior at Rockford East.

"I felt it was important for these students who are brave enough to walk out, to challenge the gun violence. I felt as a legislator it was important to let them know that they have someone who stands with them," said Illinois State Representative Litesa Wallace.

Several students shared why changing the laws is so important.

"I thought it was beautiful because a diverse group went out and stood for something that they cared about and decided they wanted to show it," said Sontino Sanchez, a junior at Rockford East.

"All these kids came together and they formed bonds that will be unbreakable and they will change this world," said Champion.

Wallace said, "We as Illinois lawmakers need to go back and make sure we override the Governor's veto and continue to pass the several other gun bills that have been introduced in the House and the Senate."

The students stayed outside for 17 minutes, a minute for each life lost in the Florida school massacre. They took a moment of silence to reflect on the loss of the innocent students killed.

"We hope that our legislatures are listening. We're calling out any of the politicians that have accepted money from the NRA. When is enough, enough?" said Alicia Neubauer, an adviser for the student walkout.
