A student who survived last week's horrific shooting at the Marjory Stoneman Douglas High School hammered Trump supporter Jack Kingston for saying that young people promoting stronger gun laws were being manipulated by liberal billionaire George Soros.

In response to former Republican Jack Kingston's claim that he and his fellow students who are organizing anti-gun rallies were being used as pawns by Soros, Marjory Stoneman Douglas High School student Brandon Abzug didn't mince words.

"I think it's very despicable that he would have the audacity to say that," he said. "Young people across this country and the world should feel they have the power to make things right, and especially in the wake of a tragedy, we show who we truly are. To say that just because we're young, we can't make a difference, is not right. He should apologize."

Fellow Stoneman Douglas shooting survivor Delaney Tarr similarly said that she hears from adults that teenagers pushing for tougher gun laws simply don't know what they're talking about -- but she said young activists have to brush it aside and concentrate on changing the system.

"With any movement, there comes this amount of hating and trolling and people saying, 'You're just a little kid, you don't know what you're talking about,' or 'You're a puppet,'" she said. "Ultimately we have to move past all that. The amount of support we're getting is so overwhelming compared to everything else."
