Deutch, a Florida Democrat who represents the district where the shooting took place, made the comments during the CNN town hall "Stand Up: The Students of Stoneman Douglas Demand Action" on Wednesday night in Sunrise, Florida.
"A lot of people have told this community -- people from all around the world -- that it's too soon," he said. "It's too soon to get together to have this kind of forum. It's too soon to talk about preventing another tragedy like the one that struck our community from happening anywhere again. It's too soon to talk about getting weapons of war out of our communities. It is not too soon. It is too late for the 17 lives that were lost."
Students and families affected by the Parkland shooting were able to ask questions about gun control and measures to prevent more mass shootings.
The town hall came after students and family members from Parkland and from Newtown, Connecticut, where 26 people were killed by a gunman at Sandy Hook Elementary School in 2012, went to the White House for a listening session earlier Wednesday with President Donald Trump and members of his administration.
Trump floated the idea
of arming teachers and school staff, which was met with support from many of the attendees.
"If you had a teacher who was adept with the firearm, they could end the attack very quickly," he said, stating that schools could arm up to 20% of their teachers to stop "maniacs" who may try to attack them.
Deutch was joined by Republican Sen. Marco Rubio and Democratic Sen. Bill Nelson, both of Florida. Trump and Florida Gov. Rick Scott declined to attend.
