He became emotional at times during his speech.
The lawmakers said they meant to reconsider a state law that allows 18-year-olds to buy assault rifles in Florida, even though the age for purchasing a handgun is 21.
Potential bipartisanship began to take root during the emotional tours that lawmakers took of the school site in recent days. During the simultaneous demonstrations, organized over social media, students gathered in hallways and campus plazas for 17 minutes of silence, one minute for each of the people killed in last week's shooting at Douglas.
A student from Bethesda-Chevy Chase High School headed to the rally told WUSA9's Mike Valerio that she hopes "we can change something in our society and make schools a safe place again". That group, which started with around 10 students, had grown to about 30 over the next two lunch periods, Brungardt said, with the students continuing to sit in the school's rotunda well into the afternoon. Of particular focus to the students was the availability of guns like the AR-15, which Nikolas Cruz used at their school and which the students would like to see banned.
The walkout included remarks from students, a moment of silence and was created to be 17 minutes long, one minute for each victim in Florida's shooting.
When students return to Marjory Stoneman Douglas High for the first time next Tuesday, they will be greeted by additional counselors and law enforcement.
In Washington, several hundred of young student protesters converged on the US Capitol and then the White House on Wednesday afternoon, carrying signs reading "Hold Hands Not Guns", "Keep guns out of the wrong hands" and "Abolish the NRA". Negron also met separately with a larger group of students earlier Wednesday, she said. But Stravitz said she and her schoolmates were not discouraged because they knew their efforts to bring about gun reform would not be easy. The Parkland victims are important to him, she said.
Thousands of chanting students, including survivors of the Florida school shooting, rallied at the state Capitol on Wednesday, demanding changes to gun laws and threatening to remove Republicans who refuse to address new gun-control measures.
Florida school shooter Nikolas Cruz, 19, had a history of troubling behavior and a person close to him warned the Federal Bureau of Investigation five weeks before the shooting that he was a threat - but no action was taken.
Before that move, dozens of students packed into a meeting room and peppered Negron with questions about why civilians should have continued access to assault rifles.
Progress on the polarizing issue may indeed consist of "baby steps", but thanks to the students of Stoneman Douglas, at least the debate still wages on.
They spent the night at the Leon County Civic Center. He traveled 450 miles to Tallahassee to push for gun control legislation.
Teachers have also said they are anxious to return to the school, Runcie said. City and school officials supported them.
But signaling a possible shift, state Senator Bill Galvan, slated to be the chamber's next president, called for a bill to raise the legal age for purchasing assault rifles from 18 to 21, the same as it is for handguns. "Save it as, 'Crazy Nick,"' Cruz told his new friend.
