Turning Point USA founder and president Charlie Kirk defended the use of the "lock her up" chat at the group's recent High School Leadership Summit in Washington, D.C.

“I support them chanting that because they’re frustrated and they should be frustrated,” Kirk told The Hill in an interview Wednesday.

At this week's summit for young conservatives, attendees chanted the phrase when speakers would mention Clinton.

Kirk said students were using the chant to fight a “culture war.”

“What is the philosophical point behind lock her up? Equal justice for all,” Kirk said. “But equal justice for all does not sound like a good chant, right?”

Sessions laughed at one point and acknowledged the chant.

“Lock her up,” he repeated into the microphone. "I heard that a long time over the last campaign."

On Thursday, he said he wished he had reminded students that people are "presumed innocent" until found guilty.
