A survivor of the deadly shooting at Marjory Stoneman Douglas High School criticized Sen. Marco RubioMarco Antonio RubioSenate GOP campaign arm outraises Democratic counterpart in September House passes bills to secure telecommunications infrastructure Senators call for answers from US firm over reported use of forced Uyghur labor in China MORE (R-Fla.) on Twitter early Friday, suggesting he is "easy to buy" for accepting donations from the National Rifle Association (NRA).

“We should change the names of AR-15s to ‘Marco Rubio’ because they are so easy to buy,” Stoneman Douglas junior Sarah Chadwick tweeted Friday. 

Rubio has been criticized by survivors of the shooting for accepting donations from the NRA. On Wednesday at a CNN town hall with survivors of the shooting, junior Cameron Kasky asked Rubio if he would commit to no longer accepting donations from the gun group.

“Senator Rubio, can you tell me right now that you will not accept a single donation from the NRA in the future?” Kasky asked.

Rubio didn’t directly answer, telling Kasky that “people buy into my agenda” and saying he supports both the Second Amendment and “the right of you and everyone here to be able to go to school and be safe.”

The Florida senator was repeatedly confronted during the town hall event, with the father of one girl killed during the shooting  calling Rubio’s comments “pathetically weak.”

But Rubio was also praised for attending the event, and said he would support increasing the age limit for gun purchases and regulating the sale of high-capacity magazines.

Rubio has an "A-plus" rating from the NRA and has received $3,303,355 in donations from the organization over the course of his political career.
