Marjory Stoneman Douglas High School student Cameron Kasky responded to the latest high school shooting in a tweet on Friday, telling his followers to prepare for the National Rifle Association to "boast about getting higher donations."

"At least 8 students have been shot and killed at Santa Fe High School," Kasky, a survivor of the Parkland, Fla., high school shooting, wrote on Twitter. "Prepare to watch the NRA boast about getting higher donations. Prepare to see students rise up and be called ‘civil terrorists’ and crisis actors. Prepare for the right-wing media to attack the survivors."
