Sarah Chadwick, a student at Marjory Stoneman Douglas High School, tweeted at the senator in response to his comment slamming the film’s omission as “total lunacy.”

“Where was this energy from you when 17 people [were] killed at my school?” she tweeted, alongside the senator's comment.

The tweet quickly went viral, garnering more than 3,500 retweets and 19,000 “likes” in six hours.

Rubio tweeted about the film “First Man,” which will be released next month and features Ryan Gosling as the legendary astronaut.

The senator shared a report in which Gosling defends the filmmakers' decision not to include the scene, saying that he doesn’t think Armstrong “viewed himself as an American hero.”

"This is total lunacy," Rubio tweeted. “And a disservice at a time when our people need reminders of what we can achieve when we work together. The American people paid for that mission, on rockets built by Americans, with American technology & carrying American astronauts. It wasn’t a UN mission."

As of Saturday evening, Rubio had not responded to Chadwick on Twitter. The Hill has reached out to his office for comment.

The Florida Republican was a frequent target of criticism from survivors of the Parkland shooting in the months following the attack. Students and other gun control advocates repeatedly called him out for accepting campaign donations from the National Rifle Association.
