Nine protesters were arrested for unlawful entry Thursday morning after staging a sit-in in the office of Sen. Joe Lieberman (ID-Conn.) in the Hart Senate Office Building.

About 20 to 25 protesters from CodePink, Mobilization for Health Care for All and Voters for Peace said they were asking Lieberman to sign an oath stating he would no longer accept money from insurance companies. According to the protesters, Lieberman’s staff offered to meet with them, but they were told the Senator himself was unavailable.

“We wanted to ask Lieberman to stop accepting insurance money and start representing his constituents,— protester Alexa Richardson said.

The nine who were arrested are currently being processed at Capitol Police headquarters.

Those who were not arrested moved to Room 342 in the Dirksen Senate Office Building where Lieberman was chairing a hearing of the Senate Homeland Security and Governmental Affairs Committee on financial crime. A group of four protesters could be seen hovering outside the hearing room.

“We’ve had many run-ins with Lieberman; he knows us very well,— said Medea Benjamin of CodePink.
