Hundreds of Pro-Palestine demonstrators interrupted California Democrats’ convention on Saturday in Sacramento to call for a cease-fire in Gaza, eventually forcing the cancellation of evening events.

“Due to circumstances beyond our control, and for the safety and security of our delegates and convention participants, we are canceling tonight’s caucus meetings, hospitality suites, and VoteFest taking place at the convention center,” Shery Yang, the communications director for the California Democrats told KCRA 3 in a statement. “More information for tomorrow’s General Session will be shared this evening.”

The cancelation was the culmination of a day of protests inside and outside the SAFE Credit Union Convention Center, where Democrats were meeting to vote on a U.S. Senate endorsement and to adopt an official party platform.
