Groups will come together to call for change today in Washington, D.C.,  and in Florida, just a week since 17 students were killed at a high school in Parkland, Florida.      

President Trump says school safety is a top priority for his administration.

"We will be working very, very hard on that horrible, horrible issue that took place last week in Florida,” says Trump. “We're working very hard. We're going to come up with solutions. It's been many, many years, and there have been no solutions, we're going to come up with solutions"

It’s being called a "listening session" today at the White House.

People from the Parkland, Florida community will be there, as well as people impacted from past mass shootings at schools, including Newtown and Columbine High School.

According to the White House, students, parents and teachers will be able to talk with the president about school safety and other issues.

There will also be a town hall in Florida.

Several students from Marjory Stoneman Douglas High School, and both of Florida's U.S. senators, will be there.

Organizers also invited President Trump, who won't be able to attend because of the listening session in Washington, D.C.

Florida Gov. Rick Scott was also invited, but he says he won't be there because he's working on legislative solutions in Florida's capital.

A legislative session Tuesday night at Florida’s capital began with a prayer for the victims of last week's mass shooting, and ended with the state house rejecting a ban on many semi-automatic guns and large capacity magazines.

Many students took buses from Parkland to Tallahassee and were left stunned.

One had a strong message for lawmakers.

"The next death of someone with an assault rifle here in Florida is going to be on them,” says Sheryl Acquarola. “It's going to be on them and it's going to be their fault that those people are dead and that those people aren't going to go home to their family and that there's going to be an empty space in people's lives and it's going to be their fault because they could've done something."

President Trump directed attorney general Jeff Sessions to propose regulations that would ban "bump stocks" and other devices that modify legal weapons and turn them into machine guns.
