Five animal rights protesters jumped over barricades and rushed the podium at a Bernie Sanders rally in East Oakland, California, on Monday night, prompting the Vermont senator's Secret Service detail to intervene.
One of the protesters appeared to be hit by one of the security member's baton, while another was carried out of the venue by his arms and legs.
For his part, Sanders did not seem rattled.
"We don't get intimidated easily," he said, after the protesters had been removed.
Sanders’ campaign spokesperson, Michael Briggs, said he thought security handled the episode “professionally,” although a media spokesperson for the group organizing the protest said one of its members was “assaulted.”
Zach Groff of the grassroots group Direct Action Everywhere told ABC News that they have been targeting Sanders because of his message about caring for the most vulnerable.
