At Wednesday's rally, they reiterated longstanding calls for Democratic leaders to do more to end the war in Gaza. They questioned how many more Palestinian civilians have to die before U.S. leaders impose an arms embargo on Israel and demand a ceasefire.

"We supply these weapons, so if you really wanted a ceasefire, just stop sending the weapons," Democratic U.S. Rep. Ilhan Omar of Minnesota told a group of a few dozen supporters and members of the media. "It's that simple."

She said the movement is committed to helping the Democratic Party defeat Donald Trump, but they believe that will require a change of policy on Gaza.

The tone of the rally alternated between somber and exasperated. Speakers included doctors who've traveled to Gaza to treat injured Palestinians. They recounted witnessing horrific living conditions, rampant disease and hunger, children losing parents and parents losing children.
