Turning Point USA founder Charlie Kirk leaves a legacy that was honored and commemorated by thousands at the Kennedy Center on Sunday, many of whom plan to continue his work.

The vigil was packed from row to row with attendees seeking to honor Kirk four days after he was shot and killed on a college campus in Utah. Attendees like Zane Pipkin, wearing a shirt embroidered with “1776” and 13 stars, called Kirk’s murder “horrible,” and said it “could’ve been anyone” who chooses to stand for their beliefs.
