“We’ve got to start figuring out ways to put some pressure points,” said Pocan, a former chair of the Congressional Progressive Caucus. “And one of those is deciding whether or not the assistance that we give—if it continues to go there with no strings attached.” The current chair of the CPC, Jayapal, was just as emphatic. “Our main leverage is around the aid that we give, and our diplomatic relations,” Jayapal said. She added that greater support for conditioning U.S. aid to Israel would represent a massive shift in the party. And though she doesn’t yet see widespread movement to that policy, she does see some. Jayapal was one of eight Democrats on Thursday who signed a letter to Biden calling for an indefinite hold on a $735 million arms sale to Israel. “We have a special obligation to scrutinize the actions of our close ally Israel, given our provision of weaponry and other military and diplomatic support to the Israeli government,” these Democrats wrote in their letter to Biden, calling the sale “antithetical to any efforts to try and de-escalate violence.”
