PARKLAND, Fla. _ The students of Marjory Stoneman Douglas High School are using their anger and sorrow as motivation to spark change.
Their message: "Never again."
As the teens gathered Sunday at a park not far from the school where 14 classmates and three educators were killed Wednesday, the picnic tables under the gazebo became their makeshift headquarters to continue their campaign against gun violence.
Munching on powdered donuts and pizza at the park, the students led chants of "Action now" and held up poster boards with messages such as "Gun violence is domestic terrorism" and "Enough is enough."
"We are saying as young adults, enough is enough and we are taking that message as far as possible," Emma Gonzalez, 18, a senior at Stoneman Douglas, told thousands at a rally Saturday.
The students are organizing trips to Tallahassee this week and Washington, D.C., on March 24.
"We're trying to flood different websites with our information, we're trying to get people all over the state, the country, worldwide so we can stop this from continuing," said Gonzalez, who is helping to organize the trips to the capitals.
After they attend the funeral of 16-year-old Carmen Schentrup on Tuesday morning, about 100 students will board buses to Tallahassee. While there, they have plans to meet with Democratic state Sen. Lauren Book, Attorney General Pam Bondi and high-ranking legislators.
At a rally demanding gun restrictions in Fort Lauderdale on Saturday, Gonzalez called out President Donald Trump and the NRA in a seething speech that went viral.
"When it comes to this type of stuff, I've always been looking for a platform," Gonzalez said.
There was also a considerable crowd that had gathered throughout the morning and afternoon at the school, people continuing to drop flowers at memorials and offer hugs to teary-eyed students.
It was a busy day for Gonzalez and several other students as they appeared on political talk shows Sunday morning.
On NBC's "Meet the Press" and CNN's "State of the Union," the students talked about the trips they're organizing to push for stricter gun laws, including to Tallahassee to meet with state legislators this week.
The five students responding to the shootings that killed 17 classmates and teachers at the school on Wednesday were Gonzalez, Cameron Kasky, David Hogg, Alex Wind and Jaclyn Corin.
The students have set up social media accounts for a movement they're calling "Never Again." The hashtag for the movement, #NeverAgain, has been going viral.
Using the newly created @NeverAgainMSD Twitter account, survivors have been getting the word out about a demonstration scheduled for March 24 in Washington, D.C., called the March For Our Lives, the details of which are being shared on another Twitter account created by the students in the wake of the shooting, @AMarch4OurLives.
Corin said that after a vigil Thursday night at the city's amphitheater, she started thinking about a trip to Tallahassee, and the next day she and the other four students were working together to get the word out and handle the logistics of the trip.
They've already been in contact with organizers of last year's Women's March to plan the trip to Washington.
"We are doing this for the victims, to not let them die in vain," Corin said.
Gonzalez said they're bringing a message to Trump, Gov. Rick Scott and U.S. Sen. Marco Rubio, although they said their goal should be nonpartisan.
"We are talking directly to them and all other members of the United States government that are being funded by the NRA to tell them now is the time to get on the right side of this," Gonzalez said on "Meet the Press." "We're going to maintain the momentum."
There has already been a call for a national school walkout on April 20, the 19th anniversary of the shootings at Columbine High School in Colorado.
"We're not going to let those 17 bullets we just took take us down," Kasky told Chuck Todd on "Meet the Press." "If anything, we're going to keep running and we're going to lead the rest of the nation behind us."
One of the students had a parting shot for Trump and a recent tweet blaming Democrats for a lack of action.
Trump's tweet Saturday said: "Just like they don't want to solve the DACA problem, why didn't the Democrats pass gun control legislation when they had both the House & Senate during the Obama Administration. Because they didn't want to, and now they just talk!"
"How dare you," Hogg responded.
"You're the president. You're supposed to bring us together, not divide us," he said. "How dare you. Children are dying and their blood is on your hands because of that. Please. Take action."
CNN plans a town hall with Stoneman Douglas students on Wednesday night, with Jake Tapper set to moderate.
