“Through Turning Point USA, Charlie ignited a fire in the hearts of tens of millions daily. He showed a generation that truth must never be silenced, that courage is contagious, and that freedom must be protected at all costs.”

Kirk has been credited for inspiring and rallying young conservatives to fight (and vote) for personal freedom against what he called dangerous liberal ideas, but he has also outraged millions with his views on abortion, civil rights, gender issues, gay marriage and gun rights.

Turning Point USA: ‘We will not stop until freedom prevails’

Turning Point USA, which was co-founded by Kirk in 2012, is a nonprofit organization that advocates for conservative politics on high school, college, and university campuses.

“Charlie Kirk poured his life into building a movement rooted in faith, freedom, and love of country. He believed America’s future depended on raising up a generation who would never surrender,” Turning Point USA said.

“Now the responsibility is ours. We will honor his legacy by pressing forward — not slowing down, not surrendering. This is not a time to preserve what was built. This is the time to fight harder, grow faster, and unleash the true power of the grassroots machine Charlie created.

“We will make Charlie proud. We will defend America’s future. And we will not stop until freedom prevails.”

On Sept. 18, the conservative youth activist organization announced its board had unanimously elected Erika Kirk as its new CEO and chair of the board.
