A survivor of the deadly mass shooting at a Florida high school last week has accused CNN of scripting student talking points at a televised town hall event with lawmakers on Wednesday evening.

Students affected by the shooting joined the families of victims to address school safety and gun reform issues at the event, attended by U.S. Senators Marco Rubio and Bill Nelson, Broward County Sheriff Scott Israel , and National Rifle Association spokeswoman Dana Loesch.

Colton Haab, a junior at Marjory Stoneman Douglas High School who survived last weeks’s gun massacre, was reportedly set to attend the event and had written questions he had hoped to ask panelists. But Habb told WPLG-TV that CNN wanted him to ask scripted questions.

“CNN had originally asked me to write a speech and questions and it ended up being all scripted,” Haab told the news station Wednesday night. He reportedly wanted to suggest that veterans act as armed security guards at school.

Haab is a Junior ROTC member, and he had the idea to give students in the Junior ROTC Kevlar sheets to shield them from bullets last Wednesday after Nikolas Cruz opened fire on the high school. Ultimately, the shooter did not enter that room, but had he, the shields may have protected the students from potentially fatal gunshots.

In a statement, CNN vehemently denied Haab’s accusations.

“There is absolutely no truth to this,” read a statement posted to a CNN Twitter account.

“CNN did not provide or script questions for anyone in last night’s town hall, nor have we ever.”

No other students who attended the town hall have accused CNN of scripting the event.
