Seventeen people, including 14 students, were killed in the shooting, which started a national movement for stricter gun control laws led by March For Our Lives, a group of survivors of the shooting.
“(T) he shot our school was real. Real children died and our community is still suffering today,” wrote the Parkland chapter of the organization in a tweet addressed to Greene. “You should be ashamed of yourself and resign from congress. Conspiracy theorists don’t deserve a seat in the people’s home.”
CNN contacted Greene’s office for comment.
A comment in Greene’s post said: “It’s called a reward to keep your mouth shut, because it was a planned shot with a false flag.”
“Exactly,” wrote Greene in response, according to the MMFA images.
Another commentator referred to the pension as a “(k) ick back for following the evil plan”, to which Greene replied, “My thoughts exactly !! I pay to do what he did and keep my mouth shut.”
Facebook removed comments for violating its policies after the MMFA report was published, according to a Facebook spokesman.
‘My daughter and 16 other people were murdered that day’
Survivors of the shooting and her family condemned Greene and asked her to resign.
“Apologize now or continue to spread these conspiracies and we will be sure to make the next 2 years of your life not just the last in Congress, but also hell.”
Hogg added that defenders “would also accept his resignation in lieu of an apology”
She also criticized the deputy, writing that he “allowed children to be defenseless against an active sniper. When he was supposed to protect them, he was a coward and refused to enter. He allowed 17 people to die.”
Cameron Kasky, another former student, wrote of her statement: “This, in addition to being a stupid and meaningless message, in no way addresses her by calling it a false flag. Now she is throwing gas light. Not the leave. “
Guttenberg said in reply: “You are a fraud you must resign. Be prepared to meet me directly in person to explain your conspiracy theory, and soon.”
Other groups calling for gun control, like Everytown for Gun Safety and Moms Demand Action, also called for Greene’s resignation.
Greene has a history of spreading conspiracy theories
MMFA also reported in another Facebook post by Greene, in which she said that “she has been told that Nancy Pelosi tells Hillary Clinton several times a month that ‘we need another school shooting’ to persuade the public to want strict control of weapons “.
At the time, Greene told CNN that he used media “attacks” as an “badge of honor”, but did not address previous blog posts.
