Protesters against the Gaza war staged a sit-in at a congressional office building Tuesday ahead of Israeli Prime Minister Benjamin Netanyahu’s address to Congress, with Capitol Police making multiple arrests.

Organized by Jewish Voice for Peace, protesters wearing identical red T-shirts that read “Not In Our Name” took over the Rotunda of the Cannon Building, chanting “Let Gaza Live!”

After about a half-hour of clapping and chanting, officers from the U.S. Capitol Police issued several warnings, then began arresting protesters — binding their hands with zip ties and leading them away one by one.

“I am the daughter of Holocaust survivors and I know what a Holocaust looks like,” said Jane Hirschmann, a native of Saugerties, New York, who drove down for the protest along with her two daughters — both of whom were arrested. “When we say ‘Never Again,’ we mean never for anybody.”
