This election cycle, a sprawling network of anti-Israel groups connected to left-wing megadonors has worked overtime to boost Democrats while amassing tens of millions of dollars in war chests, federal records show.

The sizable funding illustrates the scope of progressive-led efforts to back Vice President Kamala Harris and lawmakers who the left-wing activist groups are calling on to accuse Israel of committing “genocide” in Gaza. Following the Hamas-led Oct. 7 attack on the Jewish state, the activists have ramped up likening Israel to an “apartheid” state — hoping to pressure officials to adopt the same position.
