Chicago, Illinois – United States President Joe Biden’s send-off speech at the Democratic National Convention in Chicago was often interrupted by adoring chants of “Thank you, Joe.”

But outside the convention halls on Monday, thousands of protesters held signs accusing Biden of war crimes and referring to him as “Genocide Joe” in response to his support for Israel’s war in Gaza.

To Sabrene Odeh, an “uncommitted” delegate from Washington state, Biden’s words were not enough to allay her concerns about the humanitarian crisis in Gaza.

“What’s going to be enough is an arms embargo [on Israel] and a ceasefire,” Odeh told Al Jazeera after the first night of the convention.

“To be quite honest with you, Biden has given us nothing but empty words for the last 10 months,” she said. “Words are not enough any more from President Biden. We need to see action.”
