March For Our Lives founder Cameron Kasky leaves group, says he regrets trying to 'embarrass' Sen. Marco Rubio after Stoneman Douglas shooting

Cameron Kasky, the Marjory Stoneman Douglas High School senior and one of the founding members of the March For Our Lives movement, has quit the group.

Kasky was one of the most public faces of the group of survivors of the Feb. 14 mass shooting at the Parkland, Fla., high school, where 17 people were killed by former student Nikolas Cruz.

About a month after the massacre, Kasky and several classmates led the March For Our Lives gun control rally in Washington, D.C., which, along with hundreds of sibling events across the country, drew an estimated 1.2 million protesters.

“I’m proud of everything my friends have done, everything they’re doing, and my focus on opening these conversations to people who disagree with me makes me even more invested in just how important the work they’re doing is,” Kasky told the Miami Herald Thursday.

A week after the shooting, Kasky made waves at a CNN town hall when he confronted Sen. Marco Rubio on stage.

“Senator Rubio, it's hard to look at you and not look down a barrel of an AR-15 and not look at Nicholas Cruz, but the point is you're here and there some people who are not,” the high school student said before questioning Rubio about accepting political contributions from the NRA.

Now, Kasky said he regrets his approach.

“I look back on that and I say, you know what, there were people who had just been buried and when you're looking at somebody that you find might in some way have been complicit in this murderer obtaining the weapon it's hard not to say something like that,” he said on Fox News Radio on Wednesday. “But, I went into that wanting less conversation and more to embarrass Rubio and that was my biggest flaw.”

Recently, Kasky has partnered with Tampa Bay Buccaneers wide receiver Mike Evans and professional video game player Shay Kivlen to plan a charity video game to raise money for the families of Eli Clayton and Taylor Robertson, who were killed in the Jacksonville Madden tournament shooting last month.
