Former President Donald Trump mocked Vice President Kamala Harris‘s laugh during a rally in Asheville, North Carolina, a battleground state, Wednesday afternoon as GOP members continue to urge him to move away from juvenile attacks.

“What happened to her laugh? I haven’t heard that laugh in about a week,” Trump asked the crowd. “That’s why they keep her off the stage. That’s why she’s disappeared. That’s the laugh of a crazy person. They told her don’t laugh. Don’t laugh. Her laugh is career-threatening.”
