In a break with President Joe Biden and Senate Democratic leadership, Sen. Bernie Sanders (I-Vt.) announced Monday evening that he would vote against a supplemental spending bill to provide emergency military aid to Israel and Ukraine.

Sanders, who drew left-wing ire in recent weeks for stopping short of endorsing a permanent cease-fire in the Israel-Hamas war in Gaza, cited his concerns about the scale of Palestinian civilian deaths and displacement.

Sanders repeatedly invoked what he sees as illegal actions taken by Israeli Prime Minister Benjamin Netanyahu, leader of the most right-wing Israeli government in history.

“What the Netanyahu government is doing is immoral,” Sanders said in remarks on the Senate floor. “It is in violation of international law ― and the United States should not be complicit in those actions.”

Sander also clarified that he still supports funding for Israeli defensive technologies ― presumably including the Iron Dome missile defense system that Israel has used to stop rockets fired by Hamas, the Palestinian militant group that governs Gaza.

“I believe it is appropriate for us to support defense systems that will protect Israeli citizens from incoming missile and rocket attacks,” he said. “But I believe that it would be irresponsible for us to provide an additional $10.1 billion in unconditional military aid that will allow the Netanyahu government to continue its current offensive military approach.”
