An animal rights protester grabbed a microphone from Sen. Kamala Harris at MoveOn’s Big Ideas Forum in San Francisco Saturday afternoon.
About 10 minutes into her speech, the man, dressed in black and wearing a press badge, jumped on the stage.
Harris appeared puzzled but remained calm as the protester grabbed the mic from her hand.
The protester has been identified as a 24-year-old animal rights activist named Aidan Cook, according to BBC.com.
“We were protesting just a few minutes ago asking for your attention to a much bigger idea …” the man said, as moderator Karine Jean-Pierre tried to intervene, according to CNN.com.
Security jumped onto the stage as the senator calmly walked away from the protester.
As the man resisted leaving the stage, Harris’ husband, Douglas Emhoff, jumped in and tried to wrestle the microphone from the protester.
Harris later continued with the forum.
