Earlier Friday, Scott hailed the "historic legislation" that would help ensure that "every student in Florida has the right to learn in a safe environment".
Democratic Rep. Jared Moskowitz, a former Parkland city commissioner, ended the eight hours of debate with an emotional account of seeing the high school after the shooting, attending victims' funerals and working with students and families while the House was forming the legislation.
Meanwhile, the 19-year-old former student accused of opening fire at the school on February 14 made his initial appearance before a judge on 17 attempted murder charges added this week by the grand jury.
The bill - dubbed the Marjory Stoneman Douglas High School Public Safety Act - also extends a three-day waiting period for handgun purchases to include long guns and bans bump stocks, which allow guns to mimic fully automatic fire.
President Donald Trump congratulated Florida lawmakers, saying they "passed a lot of very good legislation last night".
Gun rights activists opposed to new gun control laws have pointed to the acknowledged breakdowns by local and federal law enforcement regarding tips about the perpetrator of the shooting, Nikolas Cruz, including multiple calls that he was a potential school shooter. "Instead of looking to the root cause of this premeditated violence, the gun control provisions in this law wrongly blame millions of Floridians who safely and responsibly exercise their right to self-defense".
"Preventing a responsible 20-year-old from purchasing the best tool for self-defense will not stop a deranged criminal intent on committing a crime", the NRA said. I am glad, however, the plan in this bill is not mandatory which means it will be up to locally elected officials.
Six other states - Wyoming, South Dakota, Tennessee, Georgia, Kansas and Texas - allow public school employees to carry firearms to work, according to the National Conference of State Legislatures.
SB 7026 also prohibits gun ownership by people mental health problems and expands the three-day waiting period that had applied only to handguns to now include long gun purchases.
The bill also creates a new program that would allow some school personnel to be armed. "It's nowhere near what we want, but it's progress and uplifting to see". While Scott would not say if he will sign it, family members of those killed said they have been asked to meet with him.
The measure violates both the U.S. Constitution's Second Amendment, which provides the right to bear arms, and the 14th Amendment, which guarantees all citizens equal protection under the law, the NRA contends.
The state teachers union urged Scott in a letter Thursday to use his line-item power to veto funding for the Guardian program.
"I'm going to take the time and I'm going to read the bill and I'm going to talk to families", Scott said.
Cruz faces 17 murder counts and 17 attempted murder counts in the shooting.
"We support the bill", Fusco said.
