(CNN) - Protesters disrupted Republican presidential candidate Michele Bachmann's foreign policy speech in Mount Pleasant, South Carolina, on Thursday, causing Bachmann to briefly leave the stage until the disturbance was over.
About a dozen protesters stood up and delivered a coordinated message, in a call-and-response format, which drowned out the Minnesota congresswoman's remarks.
A group calling itself Occupy Charleston claimed credit for the disruption, but in a message on its website said Bachmann was not the target of the action.
"She is a representative of the institutional and legal corruption that has infected our country - a system of corruption that values profit over people and is driven by the financial interests of the few against the many," the message read.
One of the protesters chanted, "We have a message for Ms. Bachmann" and the line was repeated by the group in unison.
The noise level aboard the historic aircraft carrier USS Yorktown increased when Bachmann supporters yelled at the protesters to sit down but they continued, saying, "Blaming people that disagree with you, unpatriotic socialists… this does not help the American people."
The Occupy group chanted "We are the 99 percent" as they disembarked the aircraft carrier.
Bachmann appeared shaken as a police officer escorted her off the stage, but she returned a few minutes to finish her speech.
"Don't you just love the First Amendment? It's great, we have a great country and I want to thank you all for your understanding," she said.
