President Joe Biden has been dogged for months by pro-Palestinian protesters calling him "Genocide Joe" " but some of the groups behind the demonstrations receive financial backing from philanthropists pushing hard for his reelection. The donors include some of the biggest names in Democratic circles: Gates, Soros, Rockefeller and Pritzker, according to a POLITICO analysis. Two of the main organizers behind protests at Columbia University and on other campuses are Jewish Voice for Peace and IfNotNow. Both are supported by the Tides Foundation, which is seeded by Democratic megadonor George Soros as well as the Bill and Melinda Gates Foundation, and it in turn supports numerous small nonprofits that work for social change. (Gates did not return a request for comment, and Soros declined to comment.)
